NOTICE
■Handling of the camera
●As the camera has a water proof construction, do not detach, disassemble
or modify it. This may cause incorrect operation.
● Do not subject the camera to a strong impact.
● Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
● When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunction-
ing.
● When replacing the tires, please consult your Toyota dealer. If you replace
the tires, the area displayed on the screen may change.

Four-wheel drive system
: If equipped
Use the front-wheel drive control switch to select the following
transfer modes.
*1: Vehicles with multi-information display
*2: Vehicles without multi-information display
2WD (high speed position, two-wheel drive)
Normal driving.
4H (high speed position, four-wheel drive)
Greater traction than two-wheel drive.
When you experience a loss of power, such as wheel slipping.The 4HI indicator will come on.
4L (low speed position, four-wheel drive)
Driving requiring maximum power and traction such as climbing or
descending steep hills, off-road driving and hard pulling in sand or mud,
etc.The 4LO indicator will come on.

When driving
Shifting between 4H and 4L
■ Shifting from 4H to 4L
Stop the vehicle completely.
Shift the shift lever to N.
Push and turn the front-wheel drive control switch fully clock-
wise.
Maintain this condition until the 4LO indicator comes on.
■Shifting from 4L to 4H
Stop the vehicle completely.
Shift the shift lever to N.
Turn the front-wheel drive control switch fully counterclock-
wise.
Maintain this condition until the 4LO indicator turns off.
■Shifting between 2WD and 4H
Reduce your speed to less than 62 mph (100 km/h) and set the front drive
control switch between 2WD and 4H.
When the ambient temperature is 5.0°F (-15°C) or lower, shifting from 2WD
to 4H cannot be performed with the vehicle speed above 43 mph (70 km/h)\
.
■ If the 4HI indicator blinks
●Shifting from 2WD to 4H
• If the 4HI indicator starts blinking, drive straight ahead, and try slowing
down or accelerating to allow the system to engage.
• If the 4HI indicator continues to blink and the buzzer sounds, stop the vehicle or reduce the vehicle speed to less than 62 mph (100 km/h).
Operate the switch again.
● Shifting from 4H to 2WD
If the 4HI indicator starts blinking, drive straight ahead, and try slowing
down or accelerating, or driving forward or backward for a short distance,
to allow the system to engage.

244 2-4. Using other driving systems
■If the 4LO indicator light blinks
●If the 4LO indicator continues to blink when shifting between 4H and 4L,
stop the vehicle completely, move the shift lever to N and operate the
switch again.
● If the shift lever is moved before the 4LO indicator turns on/off, the trans-
fer mode may not be shifted completely. The transfer mode disengages
both the front and rear driveshafts from the powertrain and allows the
vehicle to move regardless of the shift position. (At this time, the indicator
blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode.
To complete the shifting, stop the vehicle completely, return the shift lever
to N, and confirm that the shift was completed (The indicator turns on/off).
● If the engine coolant temperature is too low, the transfer mode may not
be able to be shifted. When the engine is warmer, operate the switch
again.
If the 4LO indicator light continues to blink even after attempting the above,
there may be a malfunction in the engine, the brake system or the four-
wheel drive system. In this case, you may not be able to shift between 4H
and 4L. Have the vehicle inspected by your Toyota dealer immediately.
■ Shifting to 4L
VSC is automatically turned off.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each
month.
This will assure that the front drive components are lubricated.

CAUTION
■Caution while driving
Never operate the front-wheel drive control switch if the wheels are slipping.
Stop the slipping or spinning before shifting.
■ When the vehicle is parked
If the shift lever is moved before the 4LO indicator turns on/off, the transfer
mode may not be shifted completely. The transfer mode disengages both the
front and rear driveshafts from the power train and allows the vehicle to move
regardless of the shift position. (At this time, the indicator blinks and the
buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P.
You or someone else could be seriously injured. You must complete the
shifting of the transfer mode before placing transmission in P. ( P. 244)

2-4. Using other driving systems
AUTO LSD system
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system should be used only wh en one of the rear wheels spin-
ning occurs in a ditch or rough surface.
■ System operation
The system can be used on 2W D models and in 2WD mode on
4WD models.
The system is activated when dr iving at a speed under 62 mph
(100 km/h).
The AUTO LSD system will be ac tivated with the following two
procedures.
Press the VSC OFF switch
briefly.
At this time, the AUTO LSD
indicator will come on.
To turn off the system, push
the switch again.
Stop the vehicle completely,
and press the VSC OFF
switch for more than 3 sec-
onds.
At this time, the VSC OFF and
AUTO LSD indicators will
come on simultaneously.
To turn off the system, push
the switch again.

When driving
When the AUTO LSD system is operating
Vehicles with multi-information display If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
Vehicles without multi-information display
■ If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The AUTO LSD system will cease operation, and the slip indicator will
change from flashing to being on continuously to alert the driver. Stop the
vehicle in a safe place. (There is no problem with continuing normal driving.)
The system will be automatically restored after a short time.

248 2-4. Using other driving systems
CAUTION
■To avoid an accident
●Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

When driving
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing engine torque when trailer
sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if
VSC is turned off or experiences a malfunction.
■ TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■A-TRAC (Active Traction Control) for 4WD mode on 4WD
models
Maintains drive power and prevents all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

250 2-4. Using other driving systems
When VSC/Trailer Sway Control/TRAC/A-TRAC are operatingVehicles with multi-information display If the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models and 2WD mode on 4WD
models) or all wheels (4WD
mode on 4WD models) spin, the
slip indicator flashes to indicate
that VSC/Trailer Sway Control/
TRAC/A-TRAC have been
engaged.
