nCruise control can be set when
lThe shift lever is in D or “4”, “5” or “6” range of S has been selected.
lVehicle speed is above 25 mph (40 km/h).
nAccelerating
The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
nAutomatic cruise control cancelation
The cruise control will stop maintaining the vehicle speed in any of the following sit-
uations:
lActual vehicle speed falls more than 10 mph (16 km/h) below the preset vehicle
speed.
At this time, the memorized set speed is not retained.
lActual vehicle speed is below 25 mph (40km/h).
lVSC is activated.
nIf the cruise control indicator light flashes
Press the “ON-OFF” button once to deactivate the system, and then press the but-
ton again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a malfunction in the cruise control system. Have

When driving
nRadar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
nWarning lights and messages for dynamic radar cruise control
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (→P. 5 5 1 )
nApproach warning
In the following instances, there is a possibility that the approach warnings will not
occur:
lWhen the speed of the vehicle ahead matches or exceeds your vehicle speed
lWhen the vehicle ahead is traveling at an extremely slow speed
lImmediately after the cruise control speed was set
lAt the instant the accelerator is applied

When driving
CAUTION
nConditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and an accident may result:
lWhen water or snow thrown up by the surrounding vehicles hinders the function-
ing of the radar sensor
lWhen your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
lWhen the road curves or when the lanes are narrow
lWhen steering wheel operation or your position in the lane is unstable
lWhen the vehicle ahead of you decelerates suddenly
nTo ensure the radar sensor functions correctly
Do not do the following to the sensor or grille as doing so may cause the sensor not
to function correctly and could result in an accident:
lSticking or attaching anything to them
lLeaving them dirty
lDisassembling or subjecting them to strong shocks
lModifying or painting them
lReplacing them with non-genuine parts
nHandling the radar sensor
Observe the following to ensure the cruise control system can function effectively:
lKeep the sensor and front grille clean at all times.
Clean the sensor and front grille with a soft cloth so you do not mark or damage
them.
lDo not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.
lDo not disassemble the sensor.
lDo not attach accessories or stickers to the sensor, grille or surrounding area.
lDo not modify or paint the sensor and grille.

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 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.
