Driving
WARNING
■If you hear a squealing or scrap- ing noise (brake pad wear indica-
tors)
Have the brake pads checked and replaced by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Front brakes only: Moderate levels of brake pad and disc wear allow
enhanced front braking power. As a result, the discs may wear more quickly than conventional brake discs.
Therefore, when replacing the brake pads, Toyota recommends that you also have the thickness of the discs
measured. It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those of the brake
discs are exceeded.
■When the vehicle is stopped
●Do not race the engine. If the vehicle is in any gear other than N, the vehicle may accelerate
suddenly and unexpectedly, caus- ing an accident.
●If the vehicle is stopped on an incline, in order to prevent acci-dents caused by the vehicle rolling
forward or backward, always depress the brake pedal and securely apply the parking brake as
needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust system to over-
heat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink
cans in the vehicle when it is in the sun.Doing so may result in the follow-
ing:
• Gas may leak from a cigarette
lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus-
ing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a place such as the glove box or on the floor, it may be lit accidentally
when luggage is loaded or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place containers such as air fresh-
eners on the instrument panel or dashboard. Adhesive discs or con-tainers may act as lenses, causing
a fire in the vehicle.
●Do not leave a door or window
open if the curved glass is coated with a metallized film such as a sil-ver-colored one. Reflected sunlight
may cause the glass to act as a lens, causing a fire.
●Always apply the parking brake, stop the engine and lock the vehi-cle.
Do not leave the vehicle unat- tended while the engine is running.

■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there
for an extended period of time. Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to
avoid damaging the wheels, under- side of the vehicle, etc.
●Make sure to idle the engine imme-diately after high-load driving. Stop the engine only after the turbo-
charger has cooled down. Failure to do so may cause damage to the turbocharger.

■When encountering flooded
roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so
may cause the following serious dam- age to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle becomes flooded or stuck in mud or
sand, be sure to have any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer check
the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine,
transmission, transfer, differential, etc.
●Lubricant condition for the propel-ler shaft, bearings and suspension joints (where possible), and the
function of all joints, bearings, etc.

wiper interval.
■Raindrop sensor
●The raindrop sensor judges the
amount of raindrops. An optical sensor is adopted. It may not operate properly when sunlight
from the rising or setting of the sun intermittently strikes the windshield, or if bugs etc. are present on the wind-
shield.
●If the wiper is turned to AUTO mode
while the engine switch is in ON, the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sen-sor is 85°C (185°F) or higher, or -15°C
(5°F) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than AUTO mode.
■If no windshield washer fluid sprays
