Maintenance and care
Washer fluid
Add washer fluid in the following
situations.
●Any washer does not work.
● The warning message
appears on the multi-informa-
tion display.
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 or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.
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 washer fluid tank.

Open the glove box, and press
and hold the tire pressure warn-
ing reset switch until the tire
pressure warning light blinks
slowly three times.
The tire pressure warning light
will flash 3 times to indicate that
initialization has started.
Wait for a few minutes with the ON mode, and then turn the
“POWER” switch OFF.
Registering ID codesThe 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 regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.

Maintenance and care
■
When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
● A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute
to indicate a system malfunction.
■ Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
■ If the tread wears down 0.16 in. (4 mm) or more on snow tires
The effectiveness of snow tires is lost.
■ If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.

■When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings has not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by your Toyota dealer.
● When operating the tire pressure warning reset switch, the tire pressure
warning light does not flash 3 times.
● After driving for a certain period of time since the initialization has been
completed, the tire pressure warning light comes on after blinking for 1
minute.
■ Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your rou-
tine of daily vehicle checks.
■ Maximum load of tire
Check that the maximum load of the replaced tire is greater than 1/2 of \
the
Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle,
whichever is greater.
For the maximum load of the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire, and for the Gross
Axle Weight Ratings (GAWR), see the Certification Label. ( P. 313, 409).

Maintenance and care
CAUTION
■
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as
dangerous handling characteristics, which may lead to fatal accidents or
injury.
●Do not mix tires of different makes, models, tread patterns or treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix radial, bias-belted, or bias-ply tires.
● Do not mix summer, all season and winter tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■ When initializing the tire pressure warning system
Do not press the tire pressure warning reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.
