6-4. Do-it-yourself maintenance
■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
zWhen rotating front and rear tires
which have different tire inflation
pressures.
zWhen changing the tire size.
zWhen the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
zWhen changing between two
registered wheel sets.
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
1Park the vehicle in a safe place
and turn the engine switch off,
wait for approximately 15 min-
utes or more and perform the
procedure.
2Adjust the tire inflation pressure
to the specified cold tire inflation
pressure level. (→P.357)
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.
3Turn the engine switch to ON.
Initialization cannot be performed while
the vehicle is moving.
4Press / of the meter con-
trol switch to select .
5Press / to select “Vehicle
Settings” and then press and
hold .
6Press / to select “TPWS
setting” and then press .
7Press / to select “Setting
Pressure”. Then press and hold
until the tire pressure warn-
ing light blinks 3 times.
Then a message will be displayed on
the multi-information display. “--” will be
displayed on the multi-information dis-
play for the inflation pressure of each
tire while initialization is being per-
formed.
8Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Even if the vehicle is not driven at
approximately 40 km/h (25 mph) or
more, initialization can be completed by
driving for a long time. However, if ini-

change of wheel set only if a sec-
ond wheel set has been regis-
tered. If no second wheel set has
been registered, the ID cannot
be changed even if “Identifying
Each Wheel & Position” is
selected in the multi-information
display and waiting for 2 min-
utes.
zOnly a change between both
registered wheel set is possible,
mixing between these wheel sets
is not supported.
■How to change between wheel
sets
1Have the vehicle fitted with the
preferred wheel set.
2Press / of the meter con-
trol switch to select .
3Press / to select “Vehicle
Settings” and then press and
hold .
4Press / to select “TPWS
setting” and then press .
5Press / to select “Identi-
fying Each Wheel & Position”.
Then press and hold until
the tire pressure warning light
blinks slowly 3 times. Afterward, turns on after flashing for 1 min-
ute.
After 2 minutes, registration of a second
wheel set is being performed and the
tire pressure warning light will turn off.
6Initialize the tire pressure warn-
ing system. (→P.282)
If the tire inflation pressure settings for
the installed tire changes, initialization
operations are required, but if the same
tire inflation pressure, initialization is
not required.
7Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Registration of a second wheel set is
complete when the tire pressure warn-
ing light turns off and the inflation pres-
sure of each tire is displayed on the
multi-information display.

3Lower the vehicle.
4 Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque: 103 N•m (10.5 kgf•m, 76 ft•lbf)
5 Stow the tire jack and all tools.
■After completing the tire change
The tire pressure warning system must be reset. ( →P.282)
Tire inflation pressure is specified
on the label on the driver’s side
door frame as shown.
Left-hand drive vehicles
Right-hand drive vehicles
WARNING
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their
storage location to reduce the possi- bility of personal injury during a colli-sion or sudden braking.
Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( →P. 3 5 7 )

Maintenance and care
zUse only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
z When rotating, repairing or
changing your tires, check that
the wheel nuts are still tight after
driving 1600 km (1000 miles).
z Be careful not to damage the
aluminum wheels when using
tire chains.
z Use only Toyota genuine balance
weights or equivalent and a plas-
tic or rubber hammer when bal-
ancing your wheels.
1 Turn the engine switch off.
2 Open the glove box. Slide off
the damper.
3 Push in the glove box on the
vehicle’s outer side to discon-
nect the 2 claws. Then pull out
the glove box and disconnect
the lower claws.
NOTICE
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-genuine wheels.

7-2. Steps to take in an emergency
ble.
■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: →P. 3 2 5
If none of the tires are punctured: Turn the engine switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( →P.282)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■Conditions that the tire pressure
warning system may not function properly
→ P. 2 8 0
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place
immediately and contact any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer.
The vehicle will become extremely unstable during braking, and the ABS system may fail, which could cause
an accident resulting in death or seri- ous injury.
■When the electric power steer-ing system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the light comes on
red, the assist to the power steering is lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following pre-
cautions. Failure to do so could cause a loss of vehicle control and result in death or
serious injury.
●Stop your vehicle in a safe place as
soon as possible. Adjust the tire inflation pressure immediately.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
