When Driving
For parking in snow, refer to Winter Driving (→P. 131) regarding parking
brake use.
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
When the disc brake pads
become worn, the built-in wear
indicators contact the disc plates.
This causes a screeching noise to
warn that the pads should be
replaced.
When you hear this noise, consult your Toyota dealer as soon as pos-
sible.
NOTICE
Driving with the parking brake on will cause excessive wear of the brake
parts.

WARNING
■ Do not drive with worn disc pads
Driving with worn disc pads is dangerous. The brakes could fail and cause a
serious accident. As soon as you hear a screeching noise consult your
Toyota dealer.

3-5. Brake
During emergency braking situations when it is necessary to depress
the brake pedal with greater force, the brake assist system provides
braking assistance, thus enhancing braking performance.
When the brake pedal is depressed hard or depressed more quickly,
the brakes apply more firmly.
● When the brake pedal is depressed hard or depressed more quickly, the
pedal will feel softer but the brakes will apply more firmly. This is a normal
effect of the brake assist operation and does not indicate a malfunction.
● When the brake pedal is depressed hard or depressed more quickly, a
motor/pump operation noise may be heard. This is a normal effect of the
brake assist and does not indicate a malfunction.
● The brake assist equipment does not supersede the functionality of the
vehicle’s main braking system.

When Driving
Antilock Brake System (ABS)
The driver will feel a slight vibration in the brake pedal and may hear a
chattering noise from the brake system. This is normal ABS system
operation. Continue to depress the brake pedal without pumping the
brakes.
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
● Braking distances may be longer on loose surfaces (snow or gravel, for
example) which usually have a hard foundation. A vehicle with a normal
braking system may require less distance to stop under these conditions
because the tires will build up a wedge of surface layer when the wheels
skid.
● The sound of the ABS operating may be heard when starting the engine or
immediately after starting the vehicle, however, it does not indicate a mal-
function.
The ABS control unit continuously monitors the speed of each
wheel. If one wheel is about to lock up, the ABS responds by
automatically releasing and reapplying that wheel’s brake.
WARNING
■ Do not rely on ABS as a substitute for safe driving
The ABS cannot compensate for unsafe and reckless driving, excessive
speed, tailgating (following another vehicle too closely), driving on ic\
e and
snow, and hydroplaning (reduced tire friction and road contact because of
water on the road surface). You can still have an accident.

Traction Control System (TCS)
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
To turn off the TCS, press the DSC OFF switch ( →P. 197).
The Traction Control System (TCS) enhances traction and safety
by controlling engine torque and braking. When the TCS detects
driving wheel slippage, it lowers engine torque and operates the
brakes to prevent loss of traction.
This means that on a slick surface, the engine adjusts automati-
cally to provide optimum power to the drive wheels, limiting
wheel spin and loss of traction.
WARNING
■ Do not rely on the Traction Control System (TCS) as a substitute for
safe driving
The Traction Control System (TCS) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
■ Use snow tires or tire chains and drive at reduced speeds when roads
are covered with ice and/or snow
Driving without proper traction devices on snow and/or ice-covered roads is
dangerous. The Traction Control System (TCS) alone cannot provide ade-
quate traction and you could still have an accident.

When Driving
Smart City Brake Support (SCBS)∗
∗: If equipped
The Smart City Brake Support (SCBS) system is designed to
reduce damage in the event of a collision by operating the brake
control (SCBS brake) when the system’s laser sensor detects a
vehicle ahead and determines that a collision with a vehicle
ahead is unavoidable. It may also be possible to avoid a colli-
sion if the relative speed between your vehicle and a vehicle
ahead is less than about 12 mph (20 km/h).
In addition, when the driver depresses the brake pedal while the
system is in the operation range at about 2 to 18 mph (4 to
30 km/h), the brakes are applied firmly and quickly to assist.

Brake/Clutch Fluid
The brakes and clutch draw fluid from the same reservoir.
Inspect the fluid level in the reser-
voir regularly. It should be kept
between the MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and
clutch linings. If it is excessively
low, have the brak e/clutch system
inspected by your Toyota dealer.
Inspecting Brake/Clutch Fluid Level
WARNING
■ If the brake/clutch fluid level is low, have the brakes inspected
A low brake/clutch fluid level is dangerous.
A low level could indicate brake lining wear or a brake system leak which
could cause the brakes to fail and lead to an accident.

■Washing
●Toyota is not responsible for scratches caused by automatic car washes or
improper washing.
● Scratches are more noticeable on vehicles with darker paint finishes.
■ 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, releasing 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 distance or the
vehicle pulling to one side when braking could result in a serious accident.
Light braking will indicate whether the brakes have been affected.
NOTICE
●Do not spray water in the engine compartment. Otherwise, it could result in
engine-starting problems or damage to electrical parts.
● When washing and waxing the vehicle, be careful not to apply excessive
force to any single area of the vehicle roof. Otherwise, you could dent the
vehicle.
● 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 and deter-
gents may discolor or deteriorate the paint.

4685-4. Appearance Care
YARIS iA_OM_OM99N89z_(U)
Road chemicals and salt used for ice and snow removal and solvents
used for dust control may collect on the underbody. If not removed,
they will speed up rusti ng and deterioration of such underbody parts
as fuel lines, frame, floor pan, a nd 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 winter. Try also to do this every month.
Pay special attention to these areas because they easily hide mud
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 tr apped there will cause
rusting.
A protective coating is provided over the aluminum wheels. Special
care is needed to protect this coating.
