nCustomization
Settings (e.g. buzzer volume) can be changed. (Customizable features →P. 6 2 1 )
CAUTION
nCaution when using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident.
lDo not use the sensor at speeds in excess of 6 mph (10 km/h).
lDo not attach any accessories within the sensor range.
NOTICE
nNotes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
nConditions possibly indicating system malfunctions
If any of the following occurs, the system may be malfunctioning due to a sensor fail-
ure etc. Have the vehicle inspected by your Lexus dealer.
lThe buzzer does not sound when the intuitive parking assist mode is set.
lThe sensor operation display flashes and the buzzer sounds even when no obsta-
cle is detected.
lAn area of the sensors is hit or subjected to a strong impact.

When driving Rear view monitor system (rea r view mirror-attached type)
∗
The rear view monitor system assists the driver by displaying an image of
the area behind the vehicle. The image is displayed in reverse on the
screen. This reversed image is a similar image to the one on the inside rear
view mirror.
The rear view image is displayed
when the shift lever is in the R
position.
If the shift lever is shifted out of
R, the screen is turned off.
∗: If equipped

nThe rear view monitor system can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode and the back door
is fully closed.
nSwitching the screen on/off
nDisplayed area
When the screen is displayed, press the
“AUTO” button on the inside rear view mirror
to switch the screen on/off
Screen on: Green indicator comes on.
Screen off: Orange indicator comes on.
The auto anti-glare inside rear view mirror
will revert to the screen on each time the
“ENGINE START STOP” switch to the
IGNITION ON mode.
The area covered by the camera is limited.
Objects that are close to either corner of
the bumper or under the bumper cannot
be seen on the screen.
The area displayed on the screen may vary
according to vehicle orientation or road
conditions.

When driving
nRear view monitor system camera
nSmear effect
In the following cases, it may become diffi-
cult to see the images on the screen, even
when the system is functioning correctly:
lThe vehicle is in a dark area, such as at
night.
lThe temperature near the lens is
extremely high or low.
lWater droplets are on the camera lens
or humidity is high, such as when it
rains.
lForeign matter, such as snow or mud,
adheres to the camera lens.
lThe sun or headlights are shining
directly into the camera lens.
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.

CAUTION
nWhen using the rear view monitor system, observe the following precautions to
avoid an accident that could result in death or serious injuries:
lNever depend solely on the monitor system when reversing.
lAlways check visually and with the mirrors to confirm your intended path is clear.
lDepicted distances between objects and flat surfaces differ from actual dis-
tances.
nConditions which may affect the rear view monitor system
lIf 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.
lRapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
lIf 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.
lThe displayed image may be darker and moving images may be slightly distorted
when the system is cold.

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.
nABS (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
nBrake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation
nVSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
nTRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
nHill-start assist control
→P. 2 3 8
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
nActive torque control 4WD system (AWD models only)
Automatically switches from front-wheel drive to AWD (All-Wheel Drive)
according to driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the
road surface is slippery due to snow or rain etc.

232
2-4. Using other driving systems
When the VSC/TRAC systems are operating
If the vehicle is in danger of slip-
ping or rolling backward when
starting on an incline, or if any of
the drive wheels spins, the slip indi-
cator light flashes to indicate that
the VSC/TRAC systems are oper-
ating.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
nEnhanced VSC (Enhanced vehicle stability control)
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.
nVDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRAC, VSC,
enhanced VSC, and hill-start assist control systems.
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes and engine output.
nPCS (Pre-Collision System) (if equipped)
→P. 2 4 0
