Maintenance and care
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.

■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, as well as
damaging the pump leading to prob- lems of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as nec-
essary.
Refer to the freezing temperatures listed on the label of the washer fluid
bottle.
Tires
Replace or rotate tires in
accordance with maintenance
schedules and treadwear.
Checking tires

■The tire pressure warning sys-
tem must be init ialized in the
following circumstances:
 When rotating front and rear tires
which have different tire inflation
pressures.
 When changing the tire size.
 When the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
When the tire pressure warning
system is initialized , the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system
1 Park the vehicle in a safe place
and turn the engine switch off.
Initialization cannot be performed while
the vehicle is moving.
2 Adjust the tire inflation pressure
to the specified co ld tire inflation
pressure level. ( P.533)
Make sure to adjust the tire pressure to
the specified cold tire inflation pressure level. The tire pressure warning system
will operate based on this pressure
level.
3 Turn the engine switch to ON.
4 Press and hold the tire pressure
warning reset switch until the
tire pressure warning light blinks
slowly 3 times.
5 Wait for a few minutes with the
engine switch in ON and then
turn the engine switch off.
■Initialization procedure
●Make sure to carry out initialization
after adjusting the tire inflation pres- sure.
Also, make sure the tires are cold
before carrying out initialization or tire inflation pressure adjustment.
NOTICE
■To avoid damage to the tire pres-
sure warning valves and trans-
mitters
When a tire is repaired with liquid
sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is used,
contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer as soon as possible. Make sure to replace the tire pressure
warning valve and transmitter when
replacing the tire. ( P.441)

Maintenance and care
●If you have accidentally turned the
engine switch off during initialization, it is not necessary to press the reset
switch again as initialization will
restart automatically when the engine switch is turned to ON the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires are cold, and conduct initialization
again.
■When initialization of the tire pres-
sure warning system has failed
Initialization can be completed in a few
minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to
record tire inflation pressure settings are unsuccessful, have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After driving for a certain period of
time since the initialization has been
completed, the wa rning light comes on after blinking for 1 minute.
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 regis-
ter the ID code. Have the ID code
registered by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
■Registering ID codes
The ID codes of the tire pressure warn- ing valve and transmitters for two sets of
wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels
of both normal tires and snow tires are registered beforehand.
For information about changing ID
codes, ask any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
WA R N I N G
■When initializing the tire pres-
sure warning system
Do not operate the tire pressure warn- ing reset switch without first adjusting
the tire inflation pressure to the speci-
fied 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.

■If the engine has to be turned off while driving
●Power assist for the brakes and
steering wheel will be lost, making the brake pedal harder to depress
and the steering wheel heavier to
turn. Decelerate as much as possi- ble before turning off the engine.
●Vehicles without a smart entry & start system: Never attempt to
remove the key, as doing so will
lock the steering wheel.
