3-5. Brake
During emergency braking situations when it is necessary to depress
the brake pedal with greater forc e, the brake assist system provides
braking assistance, thus enhancing braking performance.
When the brake pedal is depressed hard or depressed more quickl y,
the brakes apply more firmly.
● When the brake pedal is depressed hard or depressed more quickl y, t h e
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 quickl y, a
motor/pump operation noise may be heard. This is a normal effec t 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 syst em
operation. Continue to depress the brake pedal without pumping the
brakes.
The warning light turns on when the system has a malfunction.
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on
P. 493.
● Braking distances may be longer on loose surfaces (snow or grav el, for
example) which usually have a hard foundation. A vehicle with a normal
braking system may require less distance to stop under these co nditions
because the tires will build up a wedge of surface layer when t he 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 in dicate 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 su bstitute for safe driving
The ABS cannot compensate for unsafe and reckless driving, exce ssive
speed, tailgating (following another vehicle too closely), driv ing on ice and
snow, and hydroplaning (reduced tire friction and road contact because of
water on the road surface). You can still have an accident.

3-6. ABS/TCS/DSC
Traction Control System (TCS)
The warning light turns on when the system has a malfunction.
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on
P. 493.
To turn off the TCS, press the DSC OFF switch ( P. 219).
The Traction Control System (TCS) enhances traction and safety
by controlling engine torque and braking. W hen the TCS detects
driving wheel slippage, it lower s engine torque and operates th e
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 Cont rol System (TCS) as a substitute for
safe driving
The Traction Control System (TCS) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following anothe r 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-cove red roads is
dangerous. The Traction Control System (TCS) alone cannot provide ade-
quate traction and you could still have an accident.

3-10. Active Safety System
Low Speed Pre-Collision System
The Low Speed Pre-Collision System is designed to reduce
damage in the event of a colli sion by operating the brake control
(Low Speed Pre-Collision System brake) when the system’s
laser sensor detects a vehicle a head and determines that a colli-
sion with a vehicle ahead is unavo idable. It may also be possible
to avoid a collision if the relat ive 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 th e
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.

Maintenance and Care
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 brake/clutch system
inspected by your Toyota dealer.
Inspecting Brake/Clutch Fluid Level
WARNING
■ If the brake/clutch fluid level is low, have the brakes inspect ed
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 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.

4926-7. Warning/Indicator Lights and Warning Sounds
YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)
■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
Driving with the brake system warning light illuminated is dang erous. It indi-
cates that your brakes may not work at all or that they could c ompletely fail
at any time. If this light remains illuminated, after checking that the parking
brake is fully released, have the brakes inspected immediately.
In addition, the effectiveness of the braking may diminish so y ou may need
to depress the brake pedal more strongly than normal to stop th e vehicle.
■ Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to your Toyota dealer to have the
brakes inspected as soon as possible
Driving when the brake system warning light and ABS warning lig ht are illu-
minated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock mo re quickly in
an emergency stop than under normal circumstances.
NOTICE
■ Charging System Warning Light
Do not continue driving when the charging system warning light is illumi-
nated because the engine could stop unexpectedly.
■ Engine Oil Warning Light
● Do not run the engine if the oil pressure is low. Otherwise, it could result in
extensive engine damage.
● Do not run the engine if the oil level is low. Otherwise, it co uld result in
extensive engine damage.
■ High Engine Coolant Temperature Warning Light
Do not drive the vehicle with the high engine coolant temperatu re warning
light illuminated. Otherwise, it could result in damage to the engine.
