Rear view monitor system camera
■
Smear effect The rear view monitor system camera is
located on the back door as shown in the
illustration.
In the following cases, it may become diffi-
cult to see the images on the screen, even
when the system is functioning correctly: ●
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. ●
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* 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
camera, the light source appears to have
a vertical streak above and below it.

Flicker effect
When the camera is used under fluoresc ent lights, sodium lights, mercury lights
etc., the lights and the illuminated areas may appear to flicker.
CAUTION■
When using the rear view monitor system, observe the following precautions to
avoid an accident that could resu lt in death or serious injuries:●
Never depend solely on the monitor system when reversing.●
Always check visually and with the mirrors to confirm your intended path is clear.●
Use your own eyes to confirm the vehicle’s surroundings, as the displayed image
may become faint or dark, and moving imag es will be distorted, or not entirely
visible when the outside temperature is low. When backing up, be sure to check
behind and all around the vehicle visually and with the mirrors before proceeding.●
Depicted distances between objects and flat surfaces differ from actual dis-
tances.●
Do not use the system if the back door is open.

NOTICE■
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 Lexus 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 mo ving images may be slightly distorted
when the system is cold.■
Camera precautions ●
As the camera has a water proof constr uction, do not detach, disassemble or
modify it. This may cause incorrect operation.●
Do not subject the camera to a strong impact.●
If the camera lens becomes dirty, it cannot transmit a clear image. If water drop-
lets, snow, or mud adhere to the lens, rinse with water and wipe wi th a soft cloth. If
the lens is extremely dirty, wash it with a mild cleanser and rinse. Do not rub hard.●
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.●
Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
transmit a clear image.●
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 replacing tires, please consult your Lexus dealer. If you replace the tires,
the area displayed on the screen may change.

When driving Driving assist systems To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily 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
■ TRAC (Traction Control) Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
■ Hill-start assist control  P. 2 76
■ EPS (Electric Power Steering) Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■ Active Torque Control 4WD system (AWD models) Automatically switches from front-wheel drive to AWD (All-Wheel Drive)
according to driving conditions, help ing to ensure reliable handling and
stability. Examples of conditions wher e the system will switch to AWD are
when cornering, going uphill, starti ng off or accelerating, and when the
road surface is slippery due to snow or rain etc.

2702-4. Using other driving systems
When the VSC/TRAC systems are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator light flashes
to indicate that the VSC/TRAC
systems are operating. ■ Enhanced VSC (Enhanced vehicle stability control) (if equipped) Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
■ VDIM (Vehicle Dynamics Integra ted Management) (if equipped)Provides integrated control of the ABS, brake assist, TRAC, VSC, hill-start
assist control, and EPS systems.
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes and engine output.
■ PCS (Pre-Collision System) (if equipped)  P. 2 7 8
■ BSM (Blind Spot Monitor) (if equipped)  P. 2 8 6

When driving Disabling TRAC and/or VSC systems
If the vehicle gets stuck in fresh snow or mud, the TRAC/VSC systems
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.
■ Turning off the TRAC system only
To turn the TRAC system off,
quickly press and release the
switch. A message will be shown on the
multi-information display.
Press the switch again to turn the
system back on.
■ Turning off both TRAC and VSC systems
To turn the TRAC and VSC sys-
tems off, press and hold the switch
for 3 seconds or more while the
vehicle is stopped. A message will be shown on the
multi-information display and VSC
off indicator light will come on.
Press the switch again to turn the
systems back on.

2722-4. Using other driving systems
■
When the message is displayed on the multi-information display showing that
TRAC has been disabled even if the VSC off switch has not been pressed
TRAC and hill-start assist control cannot be operated. Contact your Lexus dealer.■
Sounds and vibrations caused by th e ABS, VSC, TRAC and brake assist ●
A sound may be heard from the engi ne compartment 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 operat-
ing. 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.■
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.■
Reactivation of the TRAC /VSC systems
Turning off the engine after turning off the TRAC/VSC systems will automatically
reactivate them.■
Reactivation of the TRAC sy stem linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on when vehi-
cle speed increases. However, when both TRAC and VSC systems are turned off,
the systems will not turn on even when vehicle speed increases.■
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering in put over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.
