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.

3-6. ABS/TCS/DSC
●When DSC is on and you attempt to free the vehicle when it is stuck, or
drive it out of freshly fallen snow, the TCS (part of the DSC system) will acti-
vate. Depressing the accelerator will not increase engine power and freeing
the vehicle may be difficult. When this happens, turn off the TCS/DSC.
● If the TCS/DSC is off when the engine is turned off, it automatically activates
when the ignition is switched ON.
● Leaving the TCS/DSC on will provide the best traction.
● If the DSC OFF switch is pressed and held for 10 seconds or more, the DSC
OFF switch malfunction detection function operates and the DSC system
activates automatically. The DSC OFF indicator light turns off while the DSC
system is operative.
● Vehicles with Smart City Brake Support (SCBS):
If the Smart City Brake Support (SCBS) operates with the TCS/DSC turned
off, the TCS/DSC becomes operational automatically.

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.

When Driving
If some other method besides the OFF switch was used to cancel
cruising speed (such as applying the brake pedal) and the system is
still activated, the most recent set speed will automatically resume
when the RESUME switch is pressed.
If vehicle speed is below 16 mph (25 km/h), increase the vehicle
speed up to 16 mph (25 km/h) or more and press the RESUME
switch.
To temporarily cancel the system, use one of these methods:
●Slightly depress the brake pedal.
● Manual transaxle: Depress the clutch pedal.
● Press the CANCEL switch.
If the RESUME switch is pressed when the vehicle speed is 16 mph
(25 km/h) or higher, the system reverts to the previously set speed.
● If any of the following conditions occur, the cruise control system is tempo-
rarily canceled.
• The parking brake is applied.
• Manual transaxle: The shift lever is in the neutral position.
• Automatic transaxle: The selector lever is in the P or N position.
● When the cruise control system is temporarily canceled by even one of the
applicable cancel conditions, the speed cannot be re-set.
● Automatic transaxle:
The cruise control cannot be cancelled while driving in manual mode (selec-
tor lever shifted from D to M position) . Therefore, engine braking will not be
applied even if the transaxle is shifted down to a lower gear. If deceleration
is required, lower the set speed or depress the brake pedal.
To deactivate the system, press the OFF switch.

4-1. Climate Control System
Operating Tips
●Operate the climate control system with the engine running.
● To prevent the battery from being discharged, do not leave the fan
control dial on for a long period of time with the ignition switched
ON when the engine is not running.
● Clear all obstructions such as leaves, snow and ice from the hood
and the air inlet in the cowl grille to improve the system efficiency.
● Use the climate control system to defog the windows and dehumid-
ify the air.
● The recirculate mode should be used when driving through tunnels
or while in a traffic jam, or when you would like to shut off outside
air for quick cooling of the interior.
● Use the outside air position for ventilation or windshield defrosting.
● If the vehicle has been parked in direct sunlight during hot weather,
open the windows to let warm air escape, then run the climate con-
trol system.
● Run the air conditioner about 10 minutes at least once a month to
keep internal parts lubricated.
● Have the air conditioner
checked before the weather
gets hot. Lack of refrigerant
may make the air conditioner
less efficient.
The refrigerant specifications
are indicated on a label
attached to the inside of the
engine compartment. Check
the label before refilling the
refrigerant. If the wrong type of
refrigerant is used, it could
result in a serious malfunction
of the air conditioner.
For details, consult your Toyota
dealer.
