NOTICE

In the event that you drive on a flooded

road and the vehicle is flooded, be sure

to have any authorized Lexus retailer or

Lexus authorized repairer, or any reli-

able repairer check the following:

Brake function

Changes in quantity and quality of

transmission fluid, etc.

Lubricant condition for the bearings

and suspension joints (where possi-

ble), and the function of all joints, bear-

ings, etc.

Components connected to the trac-

tion battery.

If the shift control system is damaged by
flooding, it may not be possible to shift
the shift position to P, or from P to other
positions. In this case, contact any autho-
rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.

When parking the vehicle

Always set the parking brake, and shift

the shift position to P. Failure to do so

may cause the vehicle to move or the

vehicle may accelerate suddenly if the

accelerator pedal is accidentally

depressed.

When involved in a minor accident

Damage to the traction battery or bat-

tery peripheral components could cause

malfunctions. Even if it is a minor acci-

dent, have the vehicle inspected by any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.

Cargo and luggage

Take notice of the following infor-
mation about storage precautions,
cargo capacity and load:

WARNING

Things that must not be carried in the

luggage compartment

The following things may cause a fire if

loaded in the luggage compartment:

Receptacles containing gasoline

Aerosol cans

Storage precautions

Observe the following precautions.

Failure to do so may prevent the pedals

from being depressed properly, may

block the driver’s vision, or may result in

items hitting the driver or passengers,

possibly causing an accident.

Stow cargo and luggage in the lug-

gage compartment whenever possi-

ble.

Do not stack cargo and luggage in the

luggage compartment higher than the

seatbacks.

When you fold down the rear seats,

long items should not be placed

directly behind the front seats.

Never allow anyone to ride in the lug-

gage compartment. It is not designed

for passengers. They should ride in

their seats with their seat belts prop-

erly fastened.

222

5-1. Before driving

WARNING

Do not place cargo or luggage in or on

the following locations.

• At the feet of the driver
• On the front passenger or rear seats

(when stacking items)

• On the luggage cover (if equipped)
• On the instrument panel
• On the dashboard
• In front of the Center Display

Secure all items in the occupant com-

partment.

Load and distribution

Do not overload your vehicle.

Do not apply loads unevenly.

Improper loading may cause deterio-

ration of steering or braking control

which may cause death or serious

injury.

When using a roof luggage carrier

(vehicles with roof rails)

Observe the following precautions:

Place the cargo so that its weight is

distributed evenly between the front

and rear axles.

If loading long or wide cargo, never

exceed the vehicle overall length or

width. (



P.470)

Before driving, make sure the cargo is

securely fastened on the roof luggage

carrier.

Loading cargo on the roof luggage

carrier will make the center of gravity

of the vehicle higher. Avoid high

speeds, sudden starts, sharp turns,

sudden braking or abrupt maneuvers,

otherwise it may result in loss of con-

trol or vehicle rollover due to failure to

operate this vehicle correctly and

result in death or serious injury.

If driving for a long distance, on rough

roads, or at high speeds, stop the vehi-

cle now and then during the trip to

make sure the cargo remains in its

place.

Do not exceed 80 kg (176.3 lb.) cargo

weight on the roof luggage carrier.

NOTICE

When loading cargo (vehicles with

moon roof)

Be careful not to scratch the surface of

the moon roof.

The high beams may not be automatically

changed to the shaded high beams in the

following situations:

• When vehicles ahead suddenly appear

from a curve

• When the vehicle is cut in front of by

another vehicle

• When vehicles ahead are hidden from

sight due to repeated curves, road divid-

ers or roadside trees

• When vehicles ahead appear from the

faraway lane on wide road

• When vehicles ahead have no lights

The high beams may be changed to the

shaded high beams if a vehicle ahead that

is using fog lights without its headlights

turned on is detected.

House lights, street lights, traffic signals,

and illuminated billboards or signs and

other reflective objects may cause the

high beams to change to the shaded high

beams, cause the high beams not to

change to the shaded high beams, or

change the area that is not illuminated.

The following factors may affect the

amount of time taken to turn the high

beam on or off, or the speed by which the

areas not illuminated change:

• The brightness of headlights, fog lights,

and tail lights of vehicles ahead

• The movement and direction of vehicles

ahead

• When a vehicle ahead only has opera-

tional lights on one side

• When a vehicle ahead is a two-wheeled

vehicle

• The condition of the road (gradient,

curve, condition of the road surface etc.)

• The number of passengers and amount of

luggage

The light distribution control of the head-

lights may change unexpectedly.

Bicycles or similar objects may not be

detected.

In the following situations the system may

not be able to correctly detect the sur-

rounding brightness level. This may cause

the low beams to remain on or the high

beams to flash or dazzle pedestrians or

vehicles ahead. In such a case, it is neces-

sary to manually switch between the high

and low beams.

• When driving in inclement weather

(heavy rain, snow, fog, sandstorms, etc.)
