*1: Refer to the separate “Scheduled Maintenance Guide” or “Owner’s ManualSupplement” for the maintenance interval applicable to your vehicle.
*2: Open door warning buzzer:
The open door warning buzzer sounds to alert one or more of the doors is
not fully closed (with the vehicle having reached a speed of 3 mph [5km/h]).
*3: Seat belt warning buzzer:The seat belt warning buzzer sounds to alert the driver and/or front passen-
ger that their seat belts are not fastened. If the driver’s seat belt is not fas-
tened, the buzzer will sound for 6 seconds once the “POWER” switch is
turned to ON mode. If the vehicle reaches a speed of 12 mph (20 km/h), the
buzzer will sound once. If the seat belt is still unfastened after 30 seconds,
the buzzer will sound intermittently for 10 seconds. Then, if the seat belt is
still unfastened, the buzzer will sound in a different tone for 20 more sec-
onds.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors (front door), side impact sensors (front), side
impact sensors (rear), driver’s seat position sensor, driver’s seat belt buckle
switch, front passenger occupant classification system (ECU and sensors),
“AIR BAG ON” indicator light, “AIR BA G OFF” indicator light, front passen-
ger’s seat belt buckle switch, seat belt pretensioner assemblies, airbags,
interconnecting wiring and power sources. ( P. 124)
■ Front passenger occupant classifi cation system (ECU and sensors),
seat belt reminder and warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
occupant classification system (ECU and sensors) may cause the warn-
ing 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 front passenger occupant classifi-
cation system (ECU and sensors) may not detect a passenger, and the
warning light may not operate properly.

■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the “POWER” switch
is turned to ON mode, have it
checked by your Toyota dealer.
■ Customization
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 527) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger when seat belts are not fastened.
CAUTION
■ If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steerin g system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.

Pass the belt through the buckle
and secure the tire firmly. Check
that the belt is securely held by
the buckle.
The belt cannot be fastened
securely if the buckle is facing
the wrong direction.
STEP 4
■The compact spare tire
●The compact spare tire is identifi
ed 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. 506)
■After completing the tire change
The tire pressure warning system must be reset. (P. 393)
■When using the compact spare tire
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.
■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.

CAUTION
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m, 10.5 kgf•m) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifi- cally designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.
• When installing the wheel nuts, be sure to install the wheel nuts
with the tapered end facing inward. ( P. 405)
■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 po ssibility of personal injury during a
collision or sudden braking.
■When stowing the flat tire
●Make sure the rear seatbacks are in their original position.
●Secure it using a tire tie-down belt. Otherwise, the flat tire may fly out
in case of sudden braking or an a ccident, resulting in death or serious
injury.
