■How to initialize the tire pressure warning systemPark the vehicle in a safe place and turn the engine switch to the
“LOCK” position.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire pressure to the specified cold tire inflation pres-
sure level. ( →P. 469)
Make sure to adjust the tire pressu re to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the engine switch to the “ON” position.
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.
Wait for a few minutes with the eng ine switch in the “ON” position
and then turn the engine switch to the “LOCK” position.
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a

Maintenance and care
■Initializing the tire pressure warning system (vehicles with a tire
pressure warning system)
Initialize the system with the tire infl ation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.
■If you press the tire pressure warning reset switch accidentally (vehi-
cles with a tire pressure warning system)
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When the initialization of the tire pressure warning system has failed
(vehicles with a tire pressure warning system)
Initialization can be completed in a few minutes. However, in the following
cases, the settings ha s not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle in spected by your Toyota dealer.
●When operating the tire pressure wa rning 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 warning light comes on after blinks for 1 minute.

WARNING
■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 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 snow 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.
●Do not tow if your vehicle has a compact spare tire installed.
■When initializing the tire pressure warning system (vehicles with a
tire pressure warning system)
Do not operate 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.

4268-2. Steps to take in an emergency
Tire pressure warning light (except Canada)When the light comes on: Low tire inflation pressure
such as
• Natural causes ( →P. 429)
• Flat tire ( →P. 433)
→ Adjust the tire inflation pressure to the specified
level.
The light will turn off af ter a few minutes. In case
the light does not turn off even if the tire inflation
pressure is adjusted, have the system checked by
your Toyota dealer.
When the light comes on after blinking for 1 minute:
Malfunction in the tire pressure warning system.
( → P. 430)
→ Have the system checked by your Toyota dealer.
Low windshield washer fluid warning light*2
Indicate that the washer fluid level is low.
→ Add washer fluid ( →P. 369)
Maintenance required reminder light (except Canada)
Indicates that maintenance is required according to the
driven distance on the maintenance schedule.
*5
Illuminates for about 3 seconds and then flashes for about
15 seconds approximately 4500 miles (7200 km) after the
reminder light has been reset.
→ If necessary, perform maintenance.
Comes on and remains on if the distance driven exceeds
5000 miles (8000 km) after the reminder light has been
reset. (The indicator will not work properly unless the

4288-2. Steps to take in an emergency
■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors (front), side impact sensors (front door\
), side
impact sensors (rear), driver’s seat belt buckle switch, front passenger occu-
pant classification system (ECU and sensors), “AIR BAG ON” indicator, “AIR
BAG OFF” indicator, front passenger’s seat belt buckle switch, seat belt pre-
tensioners, airbags, interconnecting wiring and power sources. ( →P. 36)
■ Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger de\
tec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■ Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and \
the
warning buzzer may sounds.
■ If the malfunction indicator la mp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
■
When the tire pressure warning light comes on (vehicles with a tire
pressure warning system)
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.

4448-2. Steps to take in an emergency
■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire.
(→ P. 469)
■After completing the tire change (vehicles with a tire pressure warn-
ing system)
The tire pressure warning system must be reset. ( →P. 372)
■When using the compact spare tire (vehicles with a tire pressure
warning system)
As the compact spare tire is not equipped with a tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warning system. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the light
remains on.
■When the compact spare tire is equipped
The vehicle height may become lower when driving with the compact
spare tire compared to when driving with standard tires.
■If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle.
Perform the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the
vehicle.
Fit tire chains to the front tires.
