Maintenance and care
■Tire inflation pressure check interval
You should check tire pressure every two weeks, or at least once a
month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect ti
re inflation pressure ma y result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent re filling, have it checked by your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be mi sleading. In addition, tire infla-
tion pressures that are even just a few pounds off can degrade ride
and handling.
●Do not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

614 5-2. Steps to take in an emergency
*2: Driver’s seat belt reminder:The driver’s seat belt reminder sounds to alert the driver that his or her seat
belt is not fastened. Once the engine switch is turned to the ON or START
position, the buzzer sounds for 6 seconds. If the vehicle has reached a
speed of at least 12 mph (20 km/h), the buzzer sounds intermittently for 10
seconds. Then, if the seat belt is still unfastened, the buzzer will sound in a
different tone for 20 more seconds.
*3: Front passenger’s seat belt reminder:
The front passenger’s seat belt reminder sounds to alert the right front pas-
senger that his or her seat belt is not fastened. The buzzer sounds intermit-
tently for 10 seconds after the vehicle has reached a speed of at least 12
mph (20 km/h). Then, if the seat belt is still unfastened, the buzzer will sound
in a different tone for 20 more seconds.
