If any washer does not work or the
warning message appears on the
multi-information display, the
washer tank may be empty. Add
washer fluid.
Washer fluid
CAUTION
■When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid contains
alcohol and may catch fire if spilled on the engine etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces.
■Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the washer fluid bottle.

Check the air cleaner filter as follows:
Remove the V-bank cover ( P. 541)
Release the clips.
Lift the cover and take out the air
cleaner filter.
Inspect the outer surface of the filter,
and replace the filter if it is extremely
dirty. If the filter is only moderately
dusty, use compressed air to blow dust
out of the filter.
Clean or replace the both left and
right side filters at the same time.
Fully engage the claws and then
secure the upper cover of the air
cleaner case using the latches.

CAUTION
■To prevent inhaling dust
Wear a respirator when using compressed air to clean the air cleaner filter.
NOTICE
■To prevent damaging the engine
Do not drive with the air cleaner filter removed. Doing so causes excessive engine
wear.

Check if the treadwear indicators are showing on the tires. Also check the
tires for uneven wear, such as excessive wear on one side of the tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.

Replace or rotate tires in accord ance with maintenance schedules and
treadwear.

Maintenance and care

Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Lexus recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles) for
2WD models or 5000 km (3000
miles) for AWD models.
Vehicle with the tire pressure warning
system: Do not fail to initialize the tire
pressure warning system after tire
rotation.

Your vehicle is equipped with a tire pressure warning system that uses tire
pressure warning valves and transmitters to detect low tire inflation pres-
sure before serious problems arise.
●If the tire pressure drops below a predetermined level, the driver is
warned by a screen display and a warning light. ( P. 609, 614)
◆Installing tire pressure wa rning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes registered by your Lexus
dealer. ( P. 560)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following
circumstances:
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing
traveling speed. ( P. 660, 662)
●When changing the tire size.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
Tire pressure warning system (if equipped)
●The tire pressure detected by the tire pressure
warning system can be displayed on the multi-
information display. ( P. 133)

■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 660, 662)
Make sure to adjust the tire pressure to the specified cold tire inflation pres-
sure level. The tire pressure warning system will operate based on this pressure
level.
Turn the engine switch to IGNITION ON mode.
Press and hold the tire pres-
sure warning reset switch until
the tire pressure warning light
blinks slowly 3 times.
Wait for a few minutes with the engine switch in IGNITION ON
mode and then turn the engine switch off.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels (vehicles with the tire pressure warning system)
If the ID code of the tire pressure warning valve and transmitter is not registered, the
tire pressure warning system will not work properly. After driving for about 10 min-
utes, the tire pressure warning light blinks for 1 minute and stays on to indicate a sys-
tem malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has sel-
dom or never been used or damage is not obvious.
■Routine tire inflation pressure checks (vehicles with the tire pressure warning sys-
tem)
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■When rotating the tires (vehicles with the tire pressure warning system)
Make sure that the engine switch is off. If the tires are rotated while the engine switch
is in IGNITION ON mode, the tire position information will not be updated.
If this accidentally occurs, either turn the engine switch to off and then to IGNITION
ON mode, or initialize the system after checking that the tire pressure is properly
adjusted.
