CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■ While towing
●When towing using a rope, avoid sudden starts, etc. which place exces-
sive stress on the towing hook and rope.
The towing hook or rope may become damaged, broken debris may hit
people and cause serious damage.
● Do not turn the engine switch off (vehicles without a smart key system) or
the “POWER” switch off (vehicles with a smart key system).
There is a possibility that the steering wheel is locked and can not be oper-
ated.
■ Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing.
Be sure to transport the vehicle with the
front wheels raised or with all four
wheels raised off the ground. If the
vehicle is towed with the front wheels
contacting the ground, the drivetrain
and related parts may be damaged or
electricity generated by the operation of
the motor may cause a fire to occur

5-2. Steps to take in an emergency
*: Driver's and front passen
ger's seat belt buzzer:
The driver's and front passenger's seat belt buzzer sounds to alert the driver
and front passenger that his or her seat belt is not fastened. Once the engine
switch is turned to the “ON” or “START” position (vehicles without a smart
key system) or the “POWER” switch is turned to ON mode (vehicles with a
smart key system), the buzzer sounds for 6 seconds. If the vehicle reaches a
speed of 12 mph (20 km/h), the buzzer sounds once. If the seat belt is still
unfastened after 30 seconds, the buzzer will sound intermittently for 10 sec-
onds. Then, if the seat belt is still unfastened, the buzzer will sound in a dif-
ferent tone for 20 more seconds.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors, driver's seat belt buckle switch, front passen-
ger occupant classification system (ECU and sensors), “AIR BAG ON” indi-
cator light, “AIR BAG OFF” indicator light, front passenger's seat belt buckle
switch, seat belt pretensioner assemblies, airbags, interconnecting wiring
and power sources. ( P. 438)
■ Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection 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 passen-
ger, and the warning light may not operate properly.
■ Electric power steering system wa rning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power st eering system warning light may come on
and the warning buzzer may sound.

■
If the tire pressure warning light comes on
Be sure to observe the following precautions. 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.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If a tire is flat, change it with th e spare tire and have the flat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.
