■Rear view monitor system camera
■ Smear effect
The rear view monitor system camera is
located on the tailgate as shown in the
illustration.
In the following cases, it may become dif-
ficult to see the images on the screen,
even when the system is functioning cor-
rectly.
●The vehicle is in a dark area, such
as at night.
● The temperature near the lens is
extremely high or low.
● Water droplets are on the camera
lens or humidity is high, such as
when it rains.
● Foreign matter, such as snow or
mud, adheres to the camera lens.
● The sun or headlights are shining
directly into the camera lens.
● A bright object such as a white wall
is reflected in the mirror surface
over the monitor.
● When the camera has scratches or
dirt on it.
If a bright light, such as sunlight
reflected off the vehicle body, is picked
up by the camera, a smear effect* char-
acteristic to the camera may occur.
*: Smear effect A phenomenon that
occurs when a bright light is picked
up by the camera; when transmitted
by the camera, the light source
appears to have a vertical streak
above and below it.

■Flicker effect
When the camera is used under fluorescent lights, sodium lights, mercury
lights etc., the lights and the illuminated areas may appear to flicker.
CAUTION
■When using the rear view monito r system, observe the following pre-
cautions to avoid an accident that coul d result in death or serious inju-
ries
● Never depend solely on the rear view monitor system when reversing.
● Always check visually and with the mirrors to confirm your intended path is
clear.
● Always check the vehicle surroundi ng area, because the guide lines are
estimates of distance and location.
● The guide lines are assistant lines and do not change even if the steering
wheel is turned.
● Depicted distances between objects and flat surfaces differ from actual
distances.
● Do not use the system if the tailgate open.
■ Conditions which may affect the rear view monitor system
● If the back of the vehicle has been hit, the camera’s position and mounting
angle may have changed. Have the vehicle inspected by your Toyota
dealer.
● Rapid temperature changes, such as when hot water is poured on the
vehicle in cold weather, may cause the system to function abnormally.
● If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If extremely dirty, wash with a mild
cleanser and rinse.
● The displayed image may be darker and moving images may be slightly
distorted when the system is cold.
■ Caution while driving in reverse
Do not change modes while the vehicle is moving.

NOTICE
●As the camera has a water proof construction, do not detach, disassemble
or modify it. This may cause incorrect operation.
● If the camera lens becomes dirty, it cannot transmit a clear image. If water
droplets, snow, or mud adhere to the lens, rinse with water and wipe with a
soft cloth. If the lens is extremely dirty, wash it with a mild cleanser and
rinse.
● 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.

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.
*2*1

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.

238 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. 238)

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.
