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.

3-5. Brake
WARNING
■Do not rely completely on Hill Launch Assist (HLA)
Hill Launch Assist (HLA) is an auxiliary device for accelerating from a stop
on a slope. The system only operates for about two seconds and therefore,
relying only on the system, when accelerating from a stop is dangerous
because the vehicle may move (roll) unexpectedly and cause an accident.
The vehicle could roll depending on the vehicle’s load or if it is towing some-
thing. In addition, for vehicles with a manual transaxle, the vehicle could still
roll depending on how the clutch pedal or the accelerator pedal is operated.
Always confirm the safety around the v ehicle before starting to drive the
vehicle.

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.

3-8. Drive Selection
3
When Driving
Drive Selection (Automatic Transaxle)∗
●When the sport mode is selected, driving at higher engine speeds increases
and it may increase fuel consumption. Toyota recommends that you cancel
the sport mode on normal driving.
● Drive mode cannot be switched in the following conditions:
• ABS/TCS/DSC is operating
• Steering wheel is being operated abruptly
Press the drive selection switch to
the side (forward) to select
the sport mode.
Pull the drive selection switch to
the side (backward) to cancel
the sport mode.
●When the ignition is switched off, the sport mode is canceled.
● Depending on the driving conditions when sport mode is selected, the vehi-
cle may perform shift-down or slightly accelerate.
∗: If equipped
Drive selection is a system to switch the vehicle’s drive mode.
When the sport mode is selected, vehicle’s response against
accelerator operation is enhanced. This provides additional
quick acceleration which may be needed to safely make maneu-
vers such as lane changes, merging onto free ways, or passing
other vehicles.
WARNING
Do not use the sport mode when driving on slippery roads such as wet or
snow-covered roads. It may cause tire slipping.

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.

3-10. Active Safety System
WARNING
■Do not rely on the Smart City Brake Support System (SCBS) as a sub-
stitute for safer driving
The Smart City Brake Support (SCBS) system cannot compensate for
unsafe and reckless driving, excessive speed, tailgating (following another
vehicle too closely), and driving on slippery roads such as wet, snowy, and
icy roads (reduced tire friction and road contact because of water on the
road surface). You can still have an accident.
■ Do not rely completely on the Smart City Brake Support (SCBS) system
●The Smart City Brake Support (SCBS) system is only designed to reduce
damage in the event of a collision. Over reliance on the system leading to
the accelerator pedal or brake pedal being mistakenly operated could
result in an accident.
● The Smart City Brake Support (SCBS) is a system which operates in
response to a vehicle ahead. The system may not be able to detect or
react to two-wheeled vehicles or pedestrians.
● The laser sensor for the Smart Ci ty Brake Support (SCBS) system is
installed near the rearview mirror. To assure the correct operation of the
Smart City Brake Support (SCBS), heed the following cautions.
• Do not apply stickers to the surface of the windshield near the laser sensor (including transparent stickers). Otherwise, the laser sensor
may not be able to detect vehicles ahead which could result in an acci-
dent.
• Do not apply coating agent to the windshield. Otherwise, the laser sen- sor may not be able to detect vehicles or obstructions in front which
could result in an accident.
• Do not disassemble the laser sensor.
• If cracks or damage caused by flying gravel or debris is visible near the laser sensor, stop using the Smart City Brake Support (SCBS)
system immediately and have your vehicle inspected by your Toyota
dealer. If the vehicle continues to be driven with cracks or scratch
marks left on the windshield near the laser sensor, the system may
operate unnecessarily and cause an unexpected accident.
Refer to Stopping The Smart City Brake Support (SCBS) System
Operation on P. 210.
• When replacing the windshield wipers or windshield, consult your Toyota dealer.
● The laser sensor includes a functi on for detecting a soiled windshield and
informing the driver, however, depending on the conditions, it may not
detect plastic shopping bags, ice or snow on the windshield. In such
cases, the system cannot accurately determine a vehicle ahead and may
not be able to operate normally. Always drive carefully and pay attention to
the road ahead.
