Winter driving tips
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Power control unit 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 specified 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.
Accelerate the vehicle slowly, keep a safe distance between you and the vehicle
ahead, and drive at a reduced speed suitable to road conditions.
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.

Driving
●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.
XSide chain
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
XCross chain
0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
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 wh en installing and removing chains:
●Install and remove tire chains in a safe location.
●Install tire chains on the front tires. Do not install tire chains on the rear tires.
●Install 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.

NOTICE
■To prevent paint deterioration and corrosion on the body and components (aluminum
wheels etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated wi
th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place with low
humidity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash (vehicles with rain-sensing windshield wipers)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper blades may be
damaged.
■When cleaning the windshield
Raise the wipers in line with the windshield. ( →P. 2 8 6 )
Failure to do so may result in damage to the wipers and/or the hood.
■When using a high pressure car wash
Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.

Maintenance and care
■Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank.
■Adding fluid
Make sure to check the fluid type and prepare the necessary item.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use
only newly opened brake fluid.
Brake fluid
Fluid typeFMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Clean funnel
WA R N I N G
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage painted surfaces. If
fluid gets on your hands or in your eyes, fl ush the affected area with clean water imme-
diately. If you still experien ce discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent ref illing, there may be a serious problem.
