3-4. Switches and Controls
Hazard War ning Flasher
The hazard warning lights warn
other drivers that your vehicle is a
traffic hazard and that they must
take extreme caution when near
it.
Depress the hazard warning
flasher and all the turn signals will
flash. The hazard warning indica-
tor lights in the combination meter
flash simultaneously.
●The turn signals do not work when the hazard warning lights are on.
● Check local regulations about the use of hazard warning lights while the
vehicle is being towed to verify that it is not in violation of the law.
The hazard warning lights should always be used when you stop
on or near a roadway in an emergency.

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.

When Driving
Hill Launch Assist (HLA)∗
For vehicles with a manual transaxle, Hill Launch Assist (HLA) oper-
ates on a downward slope when the shift lever is in the reverse (R)
position, and on an upward slope when the shift lever is in a position
other than the reverse (R) position.
For vehicles with an automatic transaxle, Hill Launch Assist (HLA)
operates on a downward slope when the shift lever is in the reverse
(R) position, and on an upward slope when the shift lever is in a for-
ward gear.
●Hill Launch Assist (HLA) does not operate on a gentle slope. In addition, the
gradient of the slope on which the system will operate changes depending
on the vehicle’s load.
● Hill Launch Assist (HLA) does not operate if the parking brake is applied, the
vehicle has not stopped completely, or the clutch pedal is released.
● While Hill Launch Assist (HLA) is operating, the brake pedal may feel stiff
and vibrate, however, this does not indicate a malfunction.
● Hill Launch Assist (HLA) does not operate while the TCS/DSC indicator light
is illuminated.
Refer to Warning/Indicator Lights on P. 156.
● Hill Launch Assist (HLA) does not turn off even if the DSC OFF switch is
pressed to turn off the TCS/DSC.
∗: If equipped
Hill Launch Assist (HLA) is a function which assists the driver in
accelerating from a stop while on a slope. When the driver
releases the brake pedal and depresses the accelerator pedal
while on a slope, the function prevents the vehicle from rolling.
The braking force is maintained automatically after the brake
pedal is released on a steep grade.

3-6. ABS/TCS/DSC
3
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 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 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.

3-6. ABS/TCS/DSC
Dynamic Stability Control (DSC)
DSC operation is possible at speeds greater than 12 mph (20 km/h).
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
The Dynamic Stability Control (DSC) automatically controls
braking and engine torque in conjunction with systems such as
ABS and TCS to help control side slip when driving on slippery
surfaces, or during sudden or evasive maneuvering, enhancing
vehicle safety.
Refer to ABS (→P. 193) and TCS ( →P. 194).
WARNING
■Do not rely on the Dynamic Stability Control as a substitute for safe
driving
The Dynamic Stability Control (DSC) 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.
NOTICE
●The DSC may not operate correctly unless the following are observed:
• Use tires of the correct size specified for your Toyota on all four wheels.
• Use tires of the same manufacturer, brand and tread pattern on all four
wheels.
• Do not mix worn tires.
● The DSC may not operate correctly when tire chains are used or a tempo-
rary spare tire is installed because the tire diameter changes.

When Driving
Power Steering
●Power steering is only operable when the engine is running. If the
engine is off or if the power steering system is inoperable, you can
still steer, but it requires more physical effort.
If the steering feels stiffer than usual during normal driving or the
steering vibrates, consult your Toyota dealer.
● The warning light notifies the driver of system abnormalities and
operation conditions.
In addition, the buzzer may also activate depending on the system
abnormality or operation condition.
Refer to Warning Lights on P. 157.
Refer to Power Steering Warning Buzzer on P. 524.
NOTICE
Never hold the steering wheel to the extreme left or right for more than 5
seconds with the engine running. This could damage the power steering
system.

When Driving
●In the following cases, the laser sensor may inadvertently determine that
there is a vehicle ahead and the Smart City Brake Support (SCBS) system
may operate.
• Objects on the road at the entrance to a curve.
• Vehicles passing in the opposite lane while making a curve.
• Metal objects, bumps, or protruding objects on the road.
• When passing through a toll gate equipped with a bar.
• When passing under a vinyl curtain or flag.
• Plastic objects such as pylons.
• Two-wheeled vehicles, pedestrians, animals or standing trees.
● Manual transaxle:
If the vehicle is stopped by the SCBS operation and the clutch pedal is not
depressed, the engine stops.
● When the system operates, the user is notified by the flashing Smart City
Brake Support (SCBS) indicator light (red).
● The Smart City Brake Support (SCBS) warning light (amber) turns on when
the system has a malfunction.
Refer to Warning Lights on P. 157.

3-12. Tire Pressure Monitoring System
Tire Pressure Monitoring System∗
The system monitors the tire pres-
sures indirectly using the data
sent from the ABS wheel speed
sensors.
To allow the system to operate correctly, the system needs to be ini-
tialized with the specified tire pressure (value on the tire pressure
label). Follow the procedure and perform the initialization.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on P. 157.
∗: If equipped
The Tire Pressure Monitoring System (TPMS) monitors the air
pressure of all four tires. If the air pressure of one or more tires
is too low, the system warns the driver by indicating the tire
pressure monitoring system warning light in the combination
meter and operating a beep sound.
