Maintenance and care
■Repair and replacement
It is recommended that genuine Toyota parts be used for repair to ensure
performance of each system. If non-Toyota parts are used in replacement or
if a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
■After changing the engine oil (U.S.A. only)
After the requred maintenace is performed according to the maintenance
schedule, please reset the maintenance data.
To reset the data, follow the procedures described below:
Turn the engine switch OFF with the trip meter A reading shown.
While pressing the trip meter reset button (P. 129), turn the
engine switch to the “ON” position.
Continue to press and hold the button until the trip meter displays
000000.
■Allow inspection and repairs to be performed by a Toyota dealer
●Toyota technicians are well-trained specialists and are kept up to date
with the latest service information. They are well informed about the
operations of all systems on your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly
take care of it.

Maintenance and care
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch
OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (P. 454)
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.
Turn the engine switch to the “ON” position.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
Wait for a few minutes with the engine switch in the “ON” posi-
tion, and then turn the engine switch to the “LOCK” position.

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 of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
■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
registered, the tire pressure warning system will not work properly. After
driving for 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 they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.

Maintenance and care
■When the initialization of the tire pressure warning system has
failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings have 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 pres-
sure warning light does not flash 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for about 20
minutes.
■Routine tire inflation pressure checks
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.
■Maximum load of tire
Check that the maximum load of the replacement 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.
■Low profile tires (models not equipped with 16-inch tires)
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains
* on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.
*: Tire chains cannot be mounted on 18-inch tires.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. (P. 460)

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 han-
dling characteristics, which may lead to an accident resulting in death or
serious injury.
●Do not mix tires of different makes, models or tread patterns. Also, do not
mix tires of remarkably different treadwear.
●
Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●
Do not mix summer, all season and winter tires.
■When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure 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.
