5-5. Using the other interior features

●

The vehicle is on an inclined surface.

●

The vehicle is in a place where the earth’s 

magnetic field is subject to interference 

by artificial magnetic fields (underground 

car park/parking lot, under a steel tower, 

between buildings, roof car park/parking 

lot, near an intersection, near a large 

vehicle, etc.).

●

The vehicle has become magnetized. 

(There is a magnet or metal object near 

the inside rear view mirror.)

●

The 12-volt battery has been discon-

nected.

●

A door is open.

■

Deviation

The direction display deviates from the true direction determined by the earth’s 
magnetic field. The amount of deviation varies depending on the geographic posi-
tion of the vehicle.

If you cross over one of the map boundaries shown in illustration, the compass will deviate.
To obtain higher precision or perfect calibration, refer to “Deviation calibration”.

WARNING

■

While driving the vehicle

Do not adjust the display. Adjust the dis-

play only when the vehicle is stopped.

NOTICE

■

To avoid compass malfunctions

Do not place magnets or any metal 

objects near the inside rear view mirror.

Doing this may cause the compass sen-

sor to malfunction.

■

To ensure normal operation of the 

compass

●

Do not perform a circling calibration 

of the compass in a place where the 

earth’s magnetic field is subject to 

interference by artificial magnetic 

fields.

●

During calibration, do not operate 

electric systems (moon roof, power 

windows, etc.) as they may interfere 

with the calibration.



Working from top to bottom, liber-
ally apply water to the vehicle body, 
wheel wells and underside of the 
vehicle to remove any dirt and dust.



Wash the vehicle body using a 
sponge or soft cloth, such as a 
chamois.



For hard-to-remove marks, use car 
wash soap and rinse thoroughly with 
water.



Wipe away any water.



Wax the vehicle when the water-
proof coating deteriorates.

If water does not bead on a clean surface, 
apply wax when the vehicle body is cool.

■

Self-restoring coat

The vehicle body has a self-restoring coat-

ing that is resistant to small surface 

scratches caused in a car wash etc.

●

The coating lasts for 5 to 8 years from 

when the vehicle is delivered from the 

plant.

●

The restoration time differs depending on 

the depth of the scratch and outside tem-

perature. The restoration time may 

become shorter when the coating is 

warmed by applying warm water.

●

Deep scratches caused by keys, coins, 

etc. cannot be restored.

●

Do not use wax that contain abrasives.

■

Automatic car washes

●

Before washing the vehicle:

• Fold the mirrors

• Turn off the power back door (if 

equipped)

Start washing from the front of the vehicle. 
Extend the mirrors before driving.

●

Brushes used in automatic car washes 

may scratch the vehicle surface, parts 

(wheel, etc.) and harm your vehicle’s 

paint.

●

Rear spoiler may not be washable in 

some automatic car washes. There may 

also be an increased risk of damage to 

vehicle.

■

electronic key is within the effective 

range, the door may lock and unlock 

repeatedly. In that case, follow the follow-

ing correction procedures to wash the 

vehicle:

• Place the key in a position 6 ft. (2 m) or 

more separate from the vehicle while the 

vehicle is being washed. (Take care to 

ensure that the key is not stolen.)

• Set the electronic key to battery-saving 

mode to disable the smart access system 

with push-button start. (



P.128)

●

If the electronic key is inside the vehicle 

and a door handle becomes wet during a 

car wash, a buzzer may sound outside the 

vehicle and “Key Detected in Vehicle” 

may be shown on the multi-information 

display. To turn off the alarm, lock all the 

doors.

Engine oil consumption

A certain amount of engine oil will be con-

sumed while driving. In the following situa-

tions, oil consumption may increase, and 

engine oil may need to be refilled in 

between oil maintenance intervals.

●

When the engine is new, for example 

directly after purchasing the vehicle or 

after replacing the engine 

●

If low quality oil or oil of an inappropriate 

viscosity is used 

●

When driving at high engine speeds or 

with a heavy load, or when driving while 

accelerating or decelerating frequently

●

When leaving the engine idling for a long 

time, or when driving frequently through 

heavy traffic

■

Engine oil level rise

If the vehicle is repeatedly driven without 

the engine warmed up, moisture caused by 

dew condensation inside the engine or fuel 

which did not burn mixes into the engine oil, 

resulting in a rise in engine oil level.
However, this is not a malfunction.
For example, the engine become difficult to 

be warmed up in the following situations.

●

When driving a short distance

●

When driving at a low speed

●

When the outside temperature is low

When checking the engine oil, make sure 

that the engine is warmed up. If the engine 

oil level exceeds the refill upper limit mark, 

contact your Lexus dealer.

When to replace your vehicle’s tires

Tires should be replaced if:

●

The treadwear indicators are showing on 

a tire.

●

You have tire damage such as cuts, splits, 

cracks deep enough to expose the fabric, 

and bulges indicating internal damage.

●

A tire goes flat repeatedly or cannot be 

properly repaired due to the size or loca-

tion of a cut or other damage.

If you are not sure, consult with your Lexus 

dealer.

■

Tire life

Any tire over 6 years old must be checked 

by a qualified technician even if it has sel-

dom or never been used or damage is not 

obvious.

■

Maximum load of tire

Check that the maximum load of the 

replacement tire is greater than 1/2 of the 

Gross Axle Weight Ratings (GAWR) of 

either the front axle or the rear axle, which-

ever is greater.
For the GAWR, see the Certification Label. 

For the maximum load of the tire, see the 

load limit at maximum cold tire inflation 

pressure mentioned on the sidewall of the 

tire. (

Tire types

●

Summer tires

Summer tires are high-speed perfor-

mance tires best suited to highway driv-

ing under dry conditions. Since summer 

tires do not have the same traction per-

formance as snow tires, summer tires are 

inadequate for driving on snow-covered 

or icy roads. For driving on snow-cov-

ered roads or icy roads, the use of snow 

tires is recommended. When installing 

snow tires, be sure to replace all four 

tires.

●

All season tires

All season tires are designed to provide 

better traction in snow and to be ade-

quate for driving in most winter condi-

tions as well as for use year-round. All 

season tires, however, do not have ade-

quate traction performance compared 

with snow tires in heavy or loose snow. 

Also, all season tires fall short in accelera-

tion and handling performance com-

pared with summer tires in highway 

driving.

●

Snow tires

For driving on snow-covered roads or icy 

roads, we recommend using snow tires. If 

you need snow tires, select tires of the 

same size, construction and load capacity 

as the originally installed tires. Since your 

vehicle has radial tires as original equip-

ment, make sure your snow tires also 

have radial construction. Do not install 

studded tires without first checking local 

regulations for possible restrictions. 

Snow tires should be installed on all 

wheels. (

P.267)

■

If the tread on snow tires wears down 

below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is 

lost.

■

Replacing tires

Your vehicle may not be equipped with the 

following tools and jack for replacing a tire. 

In this case, when replacing tires with tires 

that are not run-flat tires, purchase tools 

and jack. Tools and jack can be purchased 

at your Lexus dealer.

Rotate the tires in the order shown.

To equalize tire wear and extend tire life, 
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Do not fail to initialize the tire pressure 
warning system after tire rotation.

■

When rotating the tires

Make sure that the power switch is OFF. If 

the tires are rotated while the power switch 

is in ON, the tire position information will 

not be updated.
If this accidentally occurs, either turn the 

power switch to OFF and then to ON, or 

initialize the tire pressure warning system 

after checking that the tire pressure is prop-

erly adjusted.

When run-flat tires are installed, the 
vehicle can be driven for a maximum of 
100 miles (160 km) at a speed below 
50 mph (80 km/h) after any tire goes 
flat. (However, the vehicle speed may 
not increase to near 50 mph [80 
km/h] depending on weather or driv-
ing conditions.)

A run-flat tire has a 

 mark on 

the sidewall.

Make sure to replace the flat tire before 
the vehicle has been driven for near 100 
miles (160 km). Also, do not use a repaired 
tire.

WARNING

■

When inspecting or replacing tires

Observe the following precautions to 

prevent accidents.

Failure to do so may cause damage to 

parts of the drivetrain as well as danger-

ous handling characteristics, which may 

lead to an accident resulting in death or 

serious injury.

●

Do not mix tires of different makes, 

models or tread patterns.

Also, do not mix tires of remarkably 

different treadwear.

●

Do not use tire sizes other than those 

recommended by Lexus.

●

Do not mix differently constructed 

tires (radial, bias-belted or bias-ply 

tires).

●

Do not mix summer, all season and 

snow tires.

●

Do not use tires that have been used 

on another vehicle.

Do not use tires if you do not know 

how they were used previously.

NOTICE

■

Driving on rough roads

Take particular care when driving on 

roads with loose surfaces or potholes. 

These conditions may cause losses in tire 

inflation pressure, reducing the cushion-

ing ability of the tires. In addition, driving 

on rough roads may cause damage to 

the tires themselves, as well as the vehi-

cle’s wheels and body.

■

Run-flat tires

●

The run-flat tires are for only this vehicle. 

Do not use the tires on other vehicles.

●

Do not mix run-flat tires and normal tires.

●

If non-genuine Lexus wheels are used, it 

may be impossible to sufficiently demon-

strate the performance of run-flat tires.

Your vehicle is equipped with a tire 
pressure warning system that uses tire 
pressure warning valves and transmit-
ters to detect low tire inflation pressure 
before serious problems arise.



If the tire pressure drops below a 
predetermined level, the driver is 
warned by a screen display and a 
warning light. (



P.379, 387)

The illustration used is intended as an 
example, and may differ from the image 
that is actually displayed on the multi-infor-
mation display.



The tire pressure detected by the 
tire pressure warning system can be 
displayed on the multi-information 
display. (



P.89)

■

Routine tire inflation pressure checks

The tire pressure warning system does not 

replace routine tire inflation pressure 

checks. Make sure to check tire inflation 

pressure as part of your routine of daily 

vehicle checks.

■

Tire inflation pressure

●

It may take a few minutes to display the 

tire inflation pressure after the power 

switch is turned to ON. It may also take a 

few minutes to display the tire inflation 

pressure after inflation pressure has been 

adjusted.

●

Tire inflation pressure changes with tem-

perature. The displayed values may also 

be different from the values measured 

using a tire pressure gauge.

■

Situations in which the tire pressure 

warning system may not operate prop-

erly

●

In the following cases, the tire pressure 

warning system may not operate prop-

erly.

• If non-genuine Lexus wheels are used.

• A tire has been replaced with a tire that is 

not an OE (Original Equipment) tire.

• A tire has been replaced with a tire that is 

not of the specified size.

• Tire chains etc. are equipped.

• An auxiliary-supported run-flat tire is 

equipped.

• If a window tint that affects the radio wave 

signals is installed.

• If there is a lot of snow or ice on the vehi-

cle, particularly around the wheels or 

wheel housings.

• If the tire inflation pressure is extremely 

higher than the specified level.

• If wheels without tire pressure warning 

valves and transmitters are used.

• If the ID code on the tire pressure warn-

ing valves and transmitters is not regis-

tered in the tire pressure warning 

computer.

●

Performance may be affected in the fol-

lowing situations.

• Near a TV tower, electric power plant, 

gas station, radio station, large display, 

airport or other facility that generates 

strong radio waves or electrical noise

• When carrying a portable radio, cellular 

phone, cordless phone or other wireless 

communication device

If tire position information is not correctly 
displayed due to the radio wave conditions,

the display may be corrected by driving and 
changing the radio wave conditions.

●

When the vehicle is parked, the time 

taken for the warning to start or go off 

could be extended.

●

When tire inflation pressure declines rap-

idly for example when a tire has burst, the 

warning may not function.

■

Warning performance of the tire pres-

sure warning system

The warning of the tire pressure warning 

system will change in accordance with the 

conditions under which it was initialized. For 

this reason, the system may give a warning 

even if the tire pressure does not reach a 

low enough level, or if the pressure is higher 

than the pressure that was adjusted to when 

the system was initialized.

When replacing tires or wheels, tire 
pressure warning valves and transmit-
ters must also be installed.

When new tire pressure warning valves 
and transmitters are installed, new ID 
codes must be registered in the tire pres-
sure warning computer and the tire pres-
sure warning system must be initialized. 
(



P.345)

■

When replacing the tires and wheels

If the ID code of the tire pressure warning 

valve and transmitter is not registered, the 

tire pressure warning system will not work 

properly. After driving for about 20 min-

utes, the tire pressure warning light blinks 

for 1 minute and stays on to indicate a sys-

tem malfunction.

■

The tire pressure warning system 
must be initialized in the following 
circumstances:



When rotating the tires.



When the tire inflation pressure is 
changed such as when changing tire 
size. (When there are multiple spec-
ified pressures)



After registering the ID codes.

valves and transmitters

NOTICE

■

Repairing or replacing tires, wheels, 

tire pressure warning valves, trans-

mitters and tire valve caps

●

When removing or fitting the wheels, 

tires or the tire pressure warning 

valves and transmitters, contact your 

Lexus dealer as the tire pressure warn-

ing valves and transmitters may be 

damaged if not handled correctly.

●

Make sure to install the tire valve caps. 

If the tire valve caps are not installed, 

water could enter the tire pressure 

warning valves and the tire pressure 

warning valves could be bound.

●

When replacing tire valve caps, do not 

use tire valve caps other than those 

specified. The cap may become stuck.

■

To avoid damage to the tire pressure 

warning valves and transmitters

When a tire is repaired with liquid seal-

ants, the tire pressure warning valve and 

transmitter may not operate properly. If a 

liquid sealant is used, contact your Lexus 

dealer or other qualified service shop as 

soon as possible. After use of liquid seal-

ant, make sure to replace the tire pres-

sure warning valve and transmitter when 

repairing or replacing the tire.
