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 s ystem) 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 automat ically 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 mor e, 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.
● If the Low Speed Pre-Collision System operates with the TCS/DSC turned
off, the TCS/DSC becomes operational automatically.

3-8. Drive Selection
Drive Selection (Automatic Transaxle)
●When the sport mode is selected, driving at higher engine speed s 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
• Cruise control 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.
●In the following cases, the drive selection is canceled.
• The ignition is switched OFF.
• Cruise control is set.
● Depending on the driving conditions when sport mode is selected , the vehi-
cle may perform shift-down or slightly accelerate.
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 enhanc ed. 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 a s wet or
snow-covered roads. It may cause tire slipping.

3-9. Power Steering
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 require s more physical effort.
If the steering feels stiffer than usual during normal driving or the
steering vibrates, consul t your Toyota dealer.
• The warning light notifies the driver of system abnormalities and
operation conditions.
In addition, the buzzer may als o activate depending on the syst em
abnormality or operation condition.
Refer to Stop Vehicl e in Safe Place Imme diately on P. 489.
Refer to Power Steering Warning Buzzer on P. 505.
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
●The Low Speed Pre-Collision System will not operate if the driv er is deliber-
ately performing driving operations (accelerator pedal and stee ring wheel).
● The Low Speed Pre-Collision System will operate under the follo wing condi-
tions.
• The engine is running.
• The Low Speed Pre-Collision System warning light (amber) does not illu-
minate.
• The vehicle speed is between about 2 to 18 mph (4 to 30 km/h).
• The Low Speed Pre-Collision System is not turned off.
• The DSC is not malfunctioning.
● The Low Speed Pre-Collision System detects a vehicle ahead by emitting a
near-infrared laser beam and receiving the beam reflected off the reflector
of the vehicle ahead, and then using it for the measurement. Co nsequently,
the Low Speed Pre-Collision System may not operate under the following
conditions:
• Reflection of the laser is poor due to the shape of the vehicl e ahead.
• The vehicle ahead is significantly dirty.
• Under bad weather condition, such as rain, fog and snow.
• The window washer is being used or the windshield wipers are not used when it’s raining.
• The windshield is dirty.
• The steering wheel is turned completely left or right, or the vehicle is
accelerated rapidly and comes close to the vehicle ahead.
• Trucks with low loading platforms and vehicles with an extreme ly low or
high profile.
• Vehicles with certain shapes such as a vehicle carrier.
● Under the following conditions, the Low Speed Pre-Collision Sys tem may
not operate normally.
• Heavy luggage is loaded in the luggage compartment or on the r ear seat.
• If there is the possibility of partial contact with a vehicle ahead.
• When driving on continuously curving roads, and entering and e xiting
exits.
• Elongated luggage or cargo is loaded onto installed roof rails and covers
the laser sensor.
• Exhaust gas from the vehicle in front, sand, snow, and water v apor rising
from manholes and grating, and water splashed into the air.
• When towing a malfunctioning vehicle.
• When driving with tires having significantly different wear.

3-10. Active Safety System
●In the following cases, the laser sensor may inadvertently dete rmine that
there is a vehicle ahead and the Low Speed Pre-Collision System may oper-
ate.
• 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 Low Speed Pre-Collision System operation
and the clutch pedal is not depressed, the engine stops.
● The Low Speed Pre-Collision System warning light (amber) turns on when
the system has a malfunction.
Refer to Warning Lights on P. 173.

3-11. Cruise Control
If the cruise control system temporarily canceled (such as applying
the brake pedal) and the system i s still activated, the most recent set
speed will automatically resume when the RES/ switch is pressed .
If vehicle speed is below 16 mph (25 km/h), increase the vehicl e
speed up to 16 mph (25 km/h) or m ore and press the RES/ switch.
To temporarily cancel the syst em, use one of these methods:
• Slightly depress the brake pedal.
• Manual transaxle: Depress the clutch pedal.
• Press the OFF/CAN switch.
If the RES/ switch is pressed w hen the vehicle speed is 16 mph (25
km/h) or higher, the system rev erts to the previously set speed .
●If any of the following conditions occur, the cruise control sy stem is tempo-
rarily canceled.
• The parking brake is applied.
• Manual transaxle: The shift lever is in the neutral position.
• Automatic transaxle: The select or 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 brak ing 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.

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 perio d of time with the ignition switched
ON when the engine is not running.
• Clear all obstructions such as l eaves, snow and ice from the hood
and the air inlet in t he cowl grille to imp rove the system efficiency.
• Use the climate control system to defog the windows and dehumi d-
ify the air.
• The recirculate mode should be used when driving through tunne ls
or while in a traffic jam, or when you would like to shut off o utside
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 checke d before the weather gets hot. Lack
of refrigerant may make the ai r 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.
