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

388

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 tire 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.

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 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.

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 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.

■

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.

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.

WARNING

■

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.

392

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.

WARNING

■

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.
