■Automatic car washes
● Vehicles with a canvas top: Do not use the automatic car washes.
● Fold the mirrors and remove the antenna before washing the vehicle. Start
washing from the front of the vehicle. Make sure to re-install the antenna
and extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
● Rear spoiler may not be washable in some automatic car washes. There
may also be an increased risk of damage to vehicle.
■ High pressure car washes
● Vehicles with a canvas top: Do not use the high pressure car washes.
● Do not allow the nozzles of the car wash to come within close proximity of
the windows.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ Aluminum wheels (if equipped)
● Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical clean-
ers.
Use the same mild detergent and wax as used on the paint.
● Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
● Wash detergent from the wheels immediately after use.
■ Bumpers
Do not scrub with abrasive cleaners.
WARNING
■ When cleaning the windshield
Installation area of front sensor on windshield: P. 191
■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc., to catch fire.
■ Precautions regarding the exhaust pipe
Exhaust gases cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching hot exhaust pipe can cause burns.

that indicate service is needed. Some important clues are:
● Engine misses, stumbling or pinging
● Appreciable loss of power
● Strange engine noises
● A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
● Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
● Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
● Vehicle pulls to one side when driven straight on a level road
● Strange noises related to suspension movement
● Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
