■To prevent the clutch from overheating (vehicles with a multi-mode man-
ual transmission)
● Do not use the accelerator pedal or starting assist system to hold the vehicle
on a hill.
● On an uphill incline, observe the following whenever possible:
• Maintain a safe distance from the vehicle ahead and avoid unnecessary
starting off and stopping.
• Avoid using E mode on an uphill slope. This will help to avoid unneces-
sary gear changes.
■ Front passenger detection sensor, seat belt reminder and warning
buzzer
● If luggage is placed on the front passenger seat, the front passenger detec-
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.
■ If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empt y, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer as soon
as possible.
■ 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 sound.
■ When the tire pressure warning light comes on (vehicles with the tire
pressure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 459, 481
If the tire is not punctured:
Check the tire inflation pressure after the tire temperature has lowered suffi-
ciently. Adjust the inflation pressure to the appropriate level and carry out ini-
tialization. ( P. 4 0 6 )
■ The tire pressure warning light may come on due to natural causes
(vehicles with the tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pressure changes caused by temperature.
In this case, adjusting the tire inflation pressure is at the specified level and
carry out initialization. ( P. 406)
