■Smear effect
■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 wide view front & side monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries.
●Never depend solely on the monitor system.
●Always check visually and with the mirrors to confirm your intended path is clear.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
●Do not use the system if the hood or doors are open.
If a bright light, such as sunlight reflected off
the vehicle body, is picked up by the camera,
a smear effect
* characteristic 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 cam-
era, the light source will appear to have
streaks of light emanating from it. The
streaks will also appear when the light
source is in the masked area.

CAUTION
■Conditions which may affect the wide view front & side monitor system
●If the front of the vehicle or the passenger side outside rear view mirror has been
hit, the camera’s position and mounting angle may have changed. Have the vehi-
cle inspected by your Lexus dealer.
●As the camera has a water proof construction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●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 the camera lens is extremely dirty, wash with a mild
cleanser and rinse.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
transmit a clear image.
●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.
●The displayed image may be darker and moving images may be slightly distorted
when the system is cold.
●Situations unsuitable for wide view front & side monitor
• On icy or slick road surfaces, or in snow.
• When using tire chains or emergency tires.
• On roads that are not flat or straight, such as curves or slopes.
●When washing the vehicle, do not apply intensive bursts of water to the camera
or camera area. Doing so may result in the camera malfunctioning.

■When the four-wheel drive control switch can be operated
●The “ENGINE START STOP” switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator light
●The indicator light blinks while switching between H4 and L4.
●If the low speed four-wheel drive indicator light continues to blink when you
operate the four-wheel drive control switch to the H4 or L4 position, stop the
vehicle completely, shift the shift lever securely into N and then operate the
switch again.
●If the shift lever is moved before the low speed four-wheel drive indicator turns
on/off, the transfer mode may not be shifted completely. The transfer mode dis-
engages both the front and rear drive shafts 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 shift lever is in P. You or someone
else could be seriously injured. You must complete the shifting of the transfer
mode and confirm that the indicator light has turned off (H4) or turned on (L4).
●If the engine coolant temperature is too low, the four-wheel drive control system
may not be able to shift. When the engine is warmer operate the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive
system.

■When the center differential lock/unlock switch can be operated
The “ENGINE START STOP” switch is in IGNITION ON mode.
■The center differential lock indicator light
●The indicator light blinks while locking/unlocking the center differential.
●If the center differential lock indicator light blinks and the buzzer sounds when
the center differential is locked, stop the slipping or spinning and push the
switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive
system.
■Locking/unlocking the center differential
●When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator light will come on.)
●If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse.
●Avoid turning suddenly while the center differential is locked. If you do turn sud-
denly, the difference in turning speeds between the front and rear wheels may
have a similar effect to braking, thus making driving difficult.

DAC (Downhill Assist Control system)∗
∗: If equipped
The DAC helps to prevent excessive speed on steep downhill slopes.
The system will operate when the vehicle is traveling under 15 mph
(25 km/h) and the four-wheel drive control switch is in the L4 position.
■System operation
Shift the “DAC” switch to ON.
The downhill assist control indi-
cator light comes on and the
system will operate.
When the system is in operation,
the slip indicator light will flash,
and the stop lights/high
mounted stop lights will be lit.
■Turning off the system
Shift the “DAC” switch to OFF while the system is in operation. The
downhill assist control indicator will flash as the system gradually
ceases operation, and will turn off when the system is fully off.
Shift the “DAC” switch to ON while the downhill assist control indi-
cator is flashing to start the system again.
