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

l Use fluids that are appropriate to the prevailing outside temperatures.

• Engine oil.

• Engine coolant.

• Washer fluid.

- Have a service technician inspect the level and specific gravity of battery electrolyte.

- 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.

- Tire inflation pressure falls in winter as the outside temperature falls. Add 2.9 to 4.3 psi (20 to 30 kPa, 0.2 to 0.3 kgf/cm2 or bar) to the standard tire inflation pressure.

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 road conditions.

When parking the vehicle

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 necessary, block the wheels to prevent inadvertent sliding or creeping.

Selecting snow chains

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

Side chain
1. 0.12 in. [3 mm] in diameter.

2. 1.18 in. [30 mm] in length.

3. 0.39 in. [10 mm] in width.

Cross chain
4. 0.16 in. [4 mm] in diameter.

5. 0.98 in. [25 mm] in length.

6. 0.55 in. [14 mm] in width.

Regulations on the use of snow chains

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

- Install the chains on the front tires.

- Retighten the chains after driving 1/4 - 1/2 mile (0.5 - 1.0 km).

Shifting the windshield wiper position

You can shift the wipers to the rest position manually. (In heavy snow or icy condition etc.)
Grip the hook section of the wiper arm firmly when shifting the wiper position.

To rest position

Raise the wiper in line with the windshield.

You can stand the wipers up for the rest position.

*: More than 3.9 in. (10 cm)

To retract position

Lower the wipers by pressing on the upper part of the hook section.

Snow 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 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 in the accompanying instructions.

CAUTION:
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.

Failing 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 snow 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 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 of and obtain replacement 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.
