PKSB (Parking Support
Brake)

The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that the possibility of a colli-
sion with a detected object is high, a
warning operates to urge the driver
to take evasive action. If the system
determines that the possibility of a
collision with a detected object is
extremely high, the brakes are
automatically applied to help avoid
the collision or help reduce the
impact of the collision.

WARNING

Cautions regarding the use of the

system

Do not overly rely on the system, as

doing so may lead to an accident. Always

drive while checking the safety of the sur-

roundings of the vehicle. Depending on

the vehicle and road conditions, weather,

etc., the system may not operate. The

detection capabilities of sensors and

radars are limited. Always drive while

checking the safety of the surroundings

of the vehicle.

The driver is solely responsible for safe

driving. Always drive carefully, taking

care to observe your surroundings.

The Parking Support Brake system is

designed to provide support to lessen

the severity of collisions. However, it

may not operate in some situations.

The Parking Support Brake system is

not designed to stop the vehicle com-

pletely. Additionally, even if the system

has stopped the vehicle, it is necessary

to depress the brake pedal immedi-

ately as brake control will be canceled

after approximately 2 seconds.

It is extremely dangerous to check the

system operations by intentionally

driving the vehicle into the direction of

a wall, etc. Never attempt such actions.

When to disable the Parking Support

Brake

In the following situations, disable the

Parking Support Brake as the system

may operate even though there is no

possibility of a collision.

When inspecting the vehicle using a

chassis roller, chassis dynamo or free

roller.

When loading the vehicle onto a boat,

truck or other transport vessel.

If the suspension has been modified or

tires of a size other than specified are

installed.

If the front of the vehicle is raised or

lowered due to the carried load.

When equipment that may obstruct a

sensor is installed, such as a towing

eyelet, bumper protector (an addi-

tional trim strip, etc.), bicycle carrier,

or snow plow.

When using automatic car washing

devices.

If the vehicle cannot be driven in a sta-

ble manner, such as when the vehicle

has been in an accident or is malfunc-

tioning.

When the vehicle is driven in a sporty

manner or off-road.

When the tires are not properly

inflated.

When the tires are very worn.

When tire chains, a compact spare tire

or an emergency tire puncture repair

kit are used.

NOTICE

Using tires with any kind of problem or

modifying the suspension will affect the

driving assist systems, and may cause a

system to malfunction.

Secondary Collision Brake

Do not rely solely upon the Secondary

Collision Brake. This system is designed

to help reduce the possibility of further

damage due to a secondary collision,

however, that effect changes according

to various conditions. Overly relying on

the system may result in death or serious

injury.

Use fluids that are appropriate to
the prevailing outside temperatures.

• Power control unit coolant
• Heater coolant
• Washer fluid



Have a service technician inspect
the condition of the 12-volt battery.



Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the front tires.

Ensure that all tires are the same size and
brand, and that chains match the size of the
tires.

Perform the following according to the
driving conditions:



Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water

Winter driving tips

Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.

Preparation for winter

WARNING

Driving with snow tires

Observe the following precautions to

reduce the risk of accidents.

Failure to do so may result in a loss of

vehicle control and cause death or seri-

ous injury.

Use tires of the specified size.

Maintain the recommended level of air

pressure.

Do not drive at speeds in excess of the

speed limit or the speed limit specified

for the snow tires being used.

Use snow tires on all, not just some

wheels.

Driving with tire chains

Observe the following precautions to

reduce the risk of accidents.

Failure to do so may result in the vehicle

being unable to be driven safely, and may

cause death or serious injury.

Do not drive in excess of the speed

limit specified for the tire chains being

used, or 50 km/h (30 mph), which-

ever is lower.

Avoid driving on bumpy road surfaces

or over potholes.

Avoid sudden acceleration, abrupt

steering, sudden braking and shifting

operations that cause sudden regen-

erative braking.

Slow down sufficiently before entering

a curve to ensure that vehicle control

is maintained.

Do not use LTA (Lane Tracing Assist).

NOTICE

Repairing or replacing snow tires

Request repairs or replacement of snow

tires from any authorized Lexus retailer

or Lexus authorized repairer, or any reli-

able repairer or legitimate tire retailers.

This is because the removal and attach-

ment of snow tires affects the operation

of the tire pressure warning valves and

transmitters.

Before driving the vehicle

immediately to prevent it from
freezing.



To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.



Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.



Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.

Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.



Park the vehicle and shift the shift
position to P without setting the
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the parking
brake, make sure to block the
wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly lead-
ing to an accident.

When the parking brake is in automatic

mode, release the parking brake after shift-
ing the shift position to P. (



P.234)



If the vehicle is left parked with the
brakes damp in cold temperatures,
there is a possibility of the brakes
freezing.

Use the correct tire chain size when
mounting the tire chains. Chain size is
regulated for each tire size.

Side chain:

3 mm (0.12 in.) in diameter

10 mm (0.39 in.) in width

25 mm (0.98 in.) in length

Cross chain:

4 mm (0.16 in.) in diameter

14 mm (0.55 in.) in width

25 mm (0.98 in.) in length

WARNING

When parking the vehicle

When parking the vehicle without apply-

ing the parking brake, make sure to

chock the wheels. If you do not chock the

wheels, the vehicle may move unexpect-

edly, possibly resulting in an accident.

Regulations regarding the use of tire
chains vary depending on location and
type of road. Always check local regu-
lations before installing chains.

Tire chain installation

Observe the following precautions when

installing and removing chains:

Install and remove tire chains in a safe

location.

Install tire chains on the front tires only.

Do not install tire chains on the rear tires.

Install tire chains on front tires as tightly

as possible. Retighten chains after driving

0.5 - 1.0 km (1/4 - 1/2 mile).

Install tire chains following the instruc-

tions provided with the tire chains.

To enable the windshield wipers to be
lifted when heavy snow or icy condi-
tions are expected, change the rest
position of the windshield wipers from
the retracted position below the hood
to the service position using the wiper
lever. (



Specific design characteristics give
it a higher center of gravity than
ordinary passenger cars. This vehi-
cle design feature causes this type
of vehicle to be more likely to roll-
over. Utility vehicles have a signifi-
cantly higher rollover rate than
other types of vehicles.



An advantage of the higher ground
clearance is a better view of the
road allowing you to anticipate
problems.



It is not designed for cornering at
the same speeds as ordinary pas-
senger cars any more than low-
slung sports cars designed to per-
form satisfactorily under off-road
conditions. Therefore, sharp turns at
excessive speeds may cause roll-
over.

5-5. Driving tips

Your vehicle is not designed to be
driven off-road. However, in the event
that off-road driving cannot be
avoided, please observe the following
precautions to help avoid the areas

prohibited to vehicles.



Drive your vehicle only in areas
where off-road vehicles are permit-
ted to travel.



Respect private property. Get
owner’s permission before entering
private property.



Do not enter areas that are closed.
Honor gates, barriers and signs that
restrict travel.



Stay on established roads. When
conditions are wet, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.

WARNING

Utility vehicle precautions

Always observe the following precau-

tions to minimize the risk of death or seri-

ous injury or damage to your vehicle:

In a rollover crash, an unbelted person

is significantly more likely to die than a

person wearing a seat belt. Therefore,

the driver and all passengers should

always fasten their seat belts.

Avoid sharp turns or abrupt maneu-

vers, if at all possible.

Failure to operate this vehicle cor-

rectly may result in loss of control or

vehicle rollover causing death or seri-

ous injury.

Loading cargo on the roof luggage

carrier (if equipped) will make the cen-

ter of the vehicle gravity higher. Avoid

high speeds, sudden starts, sharp

turns, sudden braking or abrupt

maneuvers, otherwise it may result in

loss of control or vehicle rollover due

to failure to operate this vehicle cor-

rectly.

Always slow down in gusty crosswinds.

Because of its profile and higher cen-

ter of gravity, your vehicle is more sen-

sitive to side winds than an ordinary

passenger car. Slowing down will

allow you to have better control.

Do not drive horizontally across steep

slopes. Driving straight up or straight

down is preferred. Your vehicle (or

any similar off-road vehicle) can tip

over sideways much more easily than

forward or backward.

Off-road driving

WARNING

Off-road driving precautions

Always observe the following precau-

tions to minimize the risk of death or seri-

ous injury or damage to your vehicle:

Drive carefully when off the road. Do

not take unnecessary risks by driving

in dangerous places.

Do not grip the steering wheel spokes

when driving off-road. A bad bump

could jerk the wheel and injure your

hands. Keep both hands and especially

your thumbs on the outside of the rim.

Always check your brakes for effec-

tiveness immediately after driving in

sand, mud, water or snow.

After driving through tall grass, mud,

rock, sand, water, etc., check that

there is no grass, bush, paper, rags,

stone, sand, etc. adhering or trapped

to the underbody. Clear off any such

matter from the underbody. If the vehi-

cle is used with these materials

trapped or adhering to the underbody,

a breakdown or fire could occur.

WARNING

When driving off-road or in rugged

terrain, do not drive at excessive

speeds, jump, make sharp turns, strike

objects, etc. This may cause loss of

control or vehicle rollover causing

death or serious injury. You are also

risking expensive damage to your

vehicle’s suspension and chassis.

NOTICE

To prevent water damage

Take all necessary safety measures to

ensure that water damage to the traction

battery, EV system or other components

does not occur.

Water entering the motor compart-

ment may cause severe damage to the

EV system.

Water entering the transmission will

cause deterioration in transmission

quality. The vehicle may not be driv-

able.

Water can wash the grease from

wheel bearings, causing rusting and

premature failure, and may also enter

the transmission case, reducing the

gear oil’s lubricating qualities.

When you drive through water

If driving through water, such as when

crossing shallow streams, first check the

depth of the water and the bottom of the

riverbed for firmness. Drive slowly and

avoid deep water.

Inspection after off-road driving

Sand and mud that has accumulated

around brake discs may affect braking

efficiency and may damage brake sys-

tem components.

Always perform a maintenance

inspection after each day of off-road

driving that has taken you through

rough terrain, sand, mud, or water.
