■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.
■When cleaning the windshield
(vehicles with rain-sensing wind- shield wipers)
Set the wiper switch to off. If the wiper
switch is in “AUTO”, the wipers may operate unexpectedly in the following
situations, and may result in hands
being caught or other serious injuries and cause damage to the wiper
blades.
Off
AUTO
●When the upper part of the wind-
shield where the raindrop sensor is located is touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps
into the raindrop sensor
■Precautions regarding the exhaust pipe
Exhaust gasses 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 a hot exhaust pipe can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor
(if equipped)
If the paint of the rear bumper is chipped or scratche d, the system may
malfunction. If this occurs, consult
any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.

and corrosion on the body and components (aluminum wheels,
etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, in sect droppings or bird droppings are present on the
paint surface
• After driving in an area contami-
nated with soot, oily smoke, mine
dust, iron powder or chemical sub- stances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gas- oline are spilled on the paint sur-
face
●If the paint is chipped or scratched,

Maintenance and care
request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con- ditioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monox-
ide 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
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P.85, 88)
If you notice any of these clues, take
your vehicle to any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment or repair.
