■

Automatic cancelation of pre-collision system
When a malfunction occurs due to sensor contaminations, etc. that results in the sensors

being unable to detect obstacles, the pre-collision system will be automatically disabled.

In this case, the system will not activate even if there is a collision possibility.

■

Obstacles not detected
The system cannot detect plastic obstacles such as pylons. There may also be occasions

when the system cannot detect pedestrians, animals, bicycles, motorcycles, trees, or

snowdrifts.

■

Conditions that may trigger the system even if there is no possibility of a collision
In any of the following situations where the frontal area of the radar sensor is interrupted,

the radar sensor may detect possibility of a frontal collision and the system may be acti-

vated.

●

When passing by an oncoming vehicle in a curve or a turn to the right or the left

●

When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,

etc.)

●

When there is a structural object (billboard, low ceiling, fluorescent light, etc.) above

the uphill road ahead

●

When driving on a narrow road or through under a low overhead structure (bridge,

tunnel, fly-under, etc.)

●

When driving on an uneven road surface

●

When there is a metal object, bump, or protrusion on the road surface

●

When vehicle’s front part is raised or lowered depending on loading conditions

●

When the direction of radar sensor is misaligned by strong impact applied on an area

around the radar sensor, etc.

●

When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve

●

When the front of your vehicle is pointing upwards (caused by towing a trailer, during

emergency towing or putting a heavy load in the luggage compartment etc.)

When the system is activated in the situations described above, there is also a possibility

that the seat belts will retract quickly and the brakes may be applied with a force greater

than normal. When the seat belt is locked in the restricted position, stop the vehicle in a

safe place, release the seat belt and refasten it.

■

When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights will turn on or flash, and warning messages will be displayed.

CAUTION

■

Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking care to

observe your surroundings.

Do not use the pre-collision system instead of normal braking operations under any

circumstances. This system will not prevent collisions or lessen damage or injuries in all

cases. Do not overly rely on this system. Failure to do so may cause an accident, result-

ing in death or serious injury.

This system has been designed to help avoid and reduce the impact of collisions. How-

ever, the system operates differently depending on the situation (

P. 375, 376). As a

result, the same level of performance may not be expected in all cases. Also, the pre-

collision brakes may not operate if the driver is depressing the brake pedal or turning

the steering wheel, as the system will determine such conditions as collision avoidance

operations.

■

Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended to assist the

driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There are

limits to the degree of assistance the system can provide, so please keep in mind the

following important points.

●

Assisting the driver in watching the road

The pre-collision system is only able to detect obstacles directly in front of the vehicle,

and only within a limited range. It is not a mechanism that allows careless or inatten-

tive driving, and it is not a system that can assist the driver in low-visibility conditions. It

is still necessary for the driver to pay close attention to the vehicle’s surroundings.

●

Assisting the driver in making correct judgment

When attempting to estimate the possibility of a collision, the only data available to

the pre-collision system is that from obstacles it has detected directly in front of the

vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant and to

determine whether or not there is a possibility of collision in any given situation.

●

Assisting the driver in taking action

The pre-collision system’s braking assist feature is designed to help reduce the sever-

ity of a collision, and so only acts when the system has judged that a collision is

unavoidable. This system is not capable of automatically avoiding a collision or bring-

ing the vehicle to a stop safely without appropriate operations performed by the

driver. For this reason, when encountering a dangerous situation the driver must take

direct and immediate action in order to ensure the safety of all involved.

CAUTION

■

When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.

●

When water or snow thrown up by the surrounding vehicles hinders the functioning

of the sensor

●

When your vehicle is pointing upwards (caused by a heavy load in the luggage com-

partment etc.)

●

Vehicles that cut in suddenly

●

Vehicles with small rear ends (trailers with no load on board etc.)

●

Motorcycles traveling in the same lane

■

Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:

●

Keep the sensor and front grille cover clean at all times.

Clean the sensor and front grille cover with a soft cloth so you do not mark or dam-

age them.

●

Do not subject the sensor or surrounding area to a strong impact.

If the sensor moves even slightly off position, the system may become inaccurate or

malfunction. If the sensor or surrounding area is subject to a strong impact, always

have the area inspected and adjusted by your Lexus dealer.

●

Do not disassemble the sensor.

●

Do not attach accessories or stickers to the sensor, grille cover or surrounding area.

●

Do not modify or paint the sensor and grille cover.

●

If the sensor needs to be replaced, contact your Lexus dealer.

■

Handling the driver monitor sensor (vehicles with driver monitor sensor)
Observe the following to ensure the driver monitor sensor can function effectively.

Failure to do so may result in a malfunction or may prevent the system from correctly

determining the direction the driver is facing, resulting in an unexpected accident.

●

Do not disassemble, damage, lift or pull on the sensor.

●

Do not touch the sensor while driving.

●

Do not wet or spill water on the sensor.

●

Do not drop anything on or allow anything to hit against the sensor. Do not subject the

sensor to an impact.

●

Make sure that there are no scratches, dirt or stickers on the side of the sensor that

faces the driver.

●

Do not place any objects in front of the side of the sensor that faces the driver or

cover the sensor.

■

Determining the direction the driver is facing (vehicles with driver monitor sensor)
The direction the driver is facing may not be determined correctly if the following con-

ditions exist:

●

There is an object between the driver monitor sensor and the driver’s face, such as

when the sensor is blocked.

●

A part of the driver’s face is covered.

●

The sensor or the driver’s face is exposed to intense light such as sunlight.

●

The driving posture is improper.

NOTICE

■

Precautions for cleaning the driver monitor sensor (vehicles with driver monitor sen-

sor)

●

Gently wipe the sensor with a soft cloth to prevent damage.

●

Wipe any excess dirt with a cloth dampened with neutral detergent, all liquids having

been wrung out of the cloth. After that, wipe again with a dry cloth.

●

Do not use benzene, thinner, glass cleaners, wax, etc.

Winter driving tips

●

Use fluids that are appropriate to the prevailing outside temperatures.

• Engine oil
• Engine coolant
• Washer fluid

●

Have a service technician inspect the condition of the battery.

●

Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear 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 imme-
diately 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 accumulated 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.

Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.

Pre-winter preparations

Before driving the vehicle

382

4-6. Driving tips

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 move the shift lever 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 leading to an accident.

●

If the vehicle is parked without setting the parking brake, confirm that the shift
lever cannot be moved out of P

: The shift lever will be locked if it is attempted to be shifted from P to any other position

without depressing the brake pedal. If the shift lever can be shifted from P, there may
be a problem with the shift lock system. Have the vehicle inspected by your Lexus
dealer immediately.

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

Side chain
(0.20 in. [5 mm] in diameter)
Cross chain
(0.25 in. [6.3 mm] in diameter)

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

●

Install tire chains on the rear tires. Do not install tire chains on the front tires.

●

Install tire chains on rear tires as tightly as possible. Retighten chains after driving 1/4 -

1/2 mile (0.5 - 1.0 km).

●

Install tire chains following the instructions provided with the tire chains.

CAUTION

■

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 serious injury.

●

Use tires of the specified size.

●

Maintain the recommended level of air pressure.

●

Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires

being used.

●

Use snow tires on all, not just some wheels.

●

Do not use LDA (Lane Departure Alert) system. (if equipped)

■

Driving with tire chains
Observe the following precautions to reduce the risk of accidents.

Failing 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 30

mph (50 km/h), whichever is lower.

●

Avoid driving on bumpy road surfaces or over potholes.

●

Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations

that cause sudden engine braking.

●

Slow down sufficiently before entering a curve to ensure that vehicle control is main-

tained.

●

Do not use LDA (Lane Departure Alert) system. (if equipped)

NOTICE

■

Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire

retailers.
This is because the removal and attachment of snow tires affects the operation of the

tire pressure warning valves and transmitters.

■

Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when tire

chains are fitted.

Off-road precautions

●

Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. And, utility vehicles have a significantly 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 passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.

This vehicle belongs to the utility vehicle class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity to
make it capable of performing in a wide variety of off-road applications.

CAUTION

■

Off-road vehicle precautions
Always observe the following precautions to minimize the risk of death, serious 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 maneuvers, if at all possible.

Failure to operate this vehicle correctly may result in loss of control or vehicle rollover

causing death or serious injury.

●

Loading cargo on the roof luggage carrier will make the center 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 correctly.

●

Always slow down in gusty crosswinds. Because of its profile and higher center of

gravity, your vehicle is more sensitive 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.

386

4-6. Driving tips

When driving your vehicle off-road, please observe the following precautions to
ensure your driving enjoyment and to help prevent the closure of areas to off-
road vehicles:

●

Drive your vehicle only in areas where off-road vehicles are permitted 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 techniques
should be changed or travel delayed to prevent damage to roads.

CAUTION

■

Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury

or damage to your vehicle:

●

Drive carefully when off the road. Do not take unnecessary risks by driving in danger-

ous 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 effectiveness immediately after driving in sand, mud,

water or snow.

●

After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no

grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody.

Clear off any such matter from the underbody. If the vehicle is used with these materi-

als trapped or adhering to the underbody, a breakdown or fire could occur.

●

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 vehi-

cle’s suspension and chassis.

NOTICE

■

To prevent the water damage
Take all necessary safety measures to ensure that water damage to the engine or other

components does not occur.

●

Water entering the engine air intake will cause severe engine damage.

●

Water entering the automatic transmission will cause deterioration in shift quality,

locking up of your transmission accompanied by vibration, and ultimately damage.

●

Water can wash the grease from wheel bearings, causing rusting and premature fail-

ure, and may also enter the differentials, transmission and transfer 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 in brake drums and around brake discs may

affect braking efficiency and may damage brake system components.

●

Always perform a maintenance inspection after each day of off-road driving that has

taken you through rough terrain, sand, mud, or water. For scheduled maintenance

information, refer to the “Warranty and Services Guide”, “Owner’s Manual Supple-

ment” or “Scheduled Maintenance”.
