Carry out the necessary preparations and inspections before driving the vehicle in winter. Always drive the vehicle in a manner appropriate to the prevailing weather conditions.

Pre-winter preparations

Use fluids that are appropriate to the prevailing outside temperatures.

• Engine oil.

• Engine/power control unit coolant.

• Washer fluid.

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.

Before driving the vehicle

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 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.

Remove any ice that has accumulated on the vehicle chassis.

Periodically check for and remove any excess ice or snow that may have accumulated in the wheel well or on the brakes.

When driving the vehicle

Accelerate the vehicle slowly and drive at a reduced speed suitable to the road conditions.

When parking the vehicle

Park the vehicle and move the shift lever to P and block the wheel under the vehicle without setting the parking brake. The parking brake may freeze up, preventing it from being released. If necessary, block the wheels to prevent inadvertent sliding or creeping.

Selecting tire chains

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

Side chain:
1. 0.12 in. (3 mm) in diameter.

2. 0.98 in. (25 mm) in length.

3. 0.43 in. (10.8 mm) in width.

Cross chain:
4. 0.15 in. (3.9 mm) in diameter.

5. 1.00 in. (25.3 mm) in length.

6. 0.54 in. (13.8 mm) in width.

Regulations on the use of tire chains

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

Install the tire chains on front 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 size specified for your vehicle.

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.

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

Avoid driving on bumpy road surfaces or over potholes.

Avoid sudden turns and braking, as use of chains may adversely affect vehicle handling.

Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.

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.
