1323-4. Adjusting the steering wheel and mirrors
From inside (if equipped)
Press the switch to fold the mir-
rors.

outward to improve visibility
around wide trailers.
■ Recommended mirror angle when to wing a trailer (vehicles with extend-
ing mirrors)
Extending the mirrors (if equipped)
Power adjust the upper part of the
mirror until an appropriate view is
obtained. It is recommended that the
outer 2/3 of the upper mirror be filled
with images other than the vehicle
and trailer.
Manually adjust the lower part of the
mirror until an appropriate view of the
towed object is obtained. It is recom-
mended that the outer 2/3 of the lower
mirror be filled with images other than
the trailer.1

Operation of each component
■Mirror operating conditions (power-adjustable type)
The engine switch is in the “ACC” or “ON” position.
■ When the mirrors are fogg ed up (vehicles with outside rear view mirror
defoggers)
Turn on the mirror defoggers to defog the mirrors. ( P. 338, 345)
■ Automatic adjustment of the mirror angle (vehicles with driving position
memory)
A desired mirror face angle can be entered to memory and recalled automa\
ti-
cally by the driving position memory. ( P. 116)
■ Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirr or is set to automatic mode, the out-
side rear view mirrors will activate in conjunction with the anti-glare inside
rear view mirror to reduce reflected light. ( P. 128)
CAUTION
■Important points while driving
Observe the following precautions while driving.
Failure to do so may result in loss of control of the vehicle and cause an
accident, resulting in death or serious injury.
● Do not adjust the mirrors while driving.
● Do not drive with the mirrors folded.
● Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■ When a mirror is moving (power-adjustable type)
To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.
■ When the mirror defoggers are opera ting (vehicles with outside rear
view mirror defoggers)
Do not touch the rear view mirror surfaces, as they can become very hot
and burn you.

1484-1. Before driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine
running. This prevents the vehicle from creeping.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and ac\
cel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty
in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 457
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 181)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

1524-1. Before driving
NOTICE
■When driving the vehicle
● Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is
accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering pump.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 476)
■ When encounterin g flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, transfer (4WD models) differentials, etc.
● Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible), and the function of all joints, bearings, etc.

2344-5. Using the driving support systems
If the vehicle gets stuck in fresh snow or mud, A-TRAC system may
reduce power from the engine to the wheels. You may need to turn
the system off to enable you to rock the vehicle in order to free it.
Stop the vehicle completely,
and press the VSC off switch
for more than 3 seconds.
The “TRACTION CONTROL
OFF” will be shown on the dis-
play.
Press the switch again to turn
the system back on.
■When the “TRAC OFF” indicator light comes on or the message is dis-
played on the multi-information disp lay showing that “TRACTION CON-
TROL OFF” has been disabled even if the VSC off switch has not been
pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC, A-
TRAC and Trailer Sway Control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ Reactivation of the TRAC/VSC/A-T RAC/Trailer Sway Control systems
Even after the TRAC/VSC/A-TRAC/Trailer Sway Control systems have been
turned off, turning the engine switch off and then on again will automatically
reactivate the TRAC/VSC/A-TRAC/Trailer Sway Control systems.
■ Reactivation of the TRAC system linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on
when vehicle speed increases. However, when both TRAC/VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.
