■Washing
●Toyota is not responsible for scratches caused by automatic car washes or
improper washing.
● Scratches are more noticeable on vehicles with darker paint fin ishes.
■ Waxing
A spot remover to remove oil, tar, and similar materials will usually also take
off the wax. Rewax these areas even if the rest of the vehicle does not need
it.
WARNING
■Dry off brakes that have become wet by driving slowly, releasin g the
accelerator pedal and lightly applying the brakes several times until
the brake performance returns to normal
Driving with wet brakes is dangerous. Increased stopping distan ce or the
vehicle pulling to one side when braking could result in a seri ous accident.
Light braking will indicate whether the brakes have been affect ed.
NOTICE
●When the wiper lever is in the AUTO position and the ignition is switched
ON, the wipers may move automatically in the following cases:
• If the windshield above the rain sensor is touched or wiped with a cloth.
• If the windshield is struck with a hand or other object from e ither outside
or inside the vehicle.
Keep hands and scrapers clear of the windshield when the wiper lever is
in the AUTO position and the ignition is switched ON as fingers could be
pinched or the wipers and wiper blades damaged when the wipers acti-
vate automatically.
If you are going to clean the windshield, be sure the wipers ar e turned off
completely (when it is most likely that the engine is left runn ing) this is par-
ticularly important when clearing ice and snow.
● Do not spray water in the engine compartment. Otherwise, it cou ld result in
engine-starting problems or damage to electrical parts.
● When washing and waxing the vehicle, be careful not to apply ex cessive
force to any single area of the vehicle roof or the antenna. Otherwise, you
could dent the vehicle or damage the antenna.
● Do not use steel wool, abrasive cleaners, or strong detergents containing
highly alkaline or caustic agents on chrome-plated or anodized aluminum
parts. This may damage the protective coating; also, cleaners a nd deter-
gents may discolor or deteriorate the paint.

4485-4. Appearance Care
YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)
Road chemicals and salt used for ice and snow removal and solvents
used for dust control may collect on the underbody. If not remo ved,
they will speed up rust ing and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust system, even though these
parts may be coated with anti-corrosive material.
Thoroughly flush the underbody and wheel housings with lukewarm or
cold water at the end of each wi nter. Try also to do this every month.
Pay special attention to these areas because they easily hide m ud
and dirt. It will do more harm than good to wet down the road grime
without removing it.
The lower edges of doors, rocker panels, and frame members have
drain holes that should not be clogged. Water trapped there wil l cause
rusting.
A protective coating is provided over the aluminum wheels. Spec ial
care is needed to protect this coating.

Electronic Brake Force Distribution System Warning
If the electronic brake force distribution control unit deter-
mines that some components are operating incorrectly,
the control unit may illuminate the brake system warning
light and the ABS warning light simultaneously. The prob-
lem is likely to be the electronic brake force distribution
system.

malfunction of the alternator or of the charging system.
Drive to the side of the road and park off the right-of-way.
Consult your Toyota dealer.

If the light illuminates or the warning indication is dis-
played while driving:
Drive to the side of the road and park off the right-of-
way on level ground.

■Power Steering Malfunction Indicator Light
●If the indicator light illuminates/flashes, the power steering will not operate
normally. If this happens, the steering wheel can still be operated, however,
the operation may feel heavy compared to normal, or the steering wheel
could vibrate when turning.
● Repeatedly jerking the steering wheel left and right while the vehicle is
stopped or moving extremely slowly will cause the power steerin g system to
go into protective mode which will make the steering feel heavy , but this
does not indicate a problem. If this occurs, park the vehicle safely and wait
several minutes for the system to return to normal.
WARNING
■ Do not drive with the brake system warning light illuminated. C ontact
your Toyota dealer to have the brakes inspected as soon as poss ible
