CAUTION
■Conditions 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 a fatal or serious accident may
result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the radar sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do 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 any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.
●Do not replace them with non-genuine parts.

CAUTION
■The electronically modulated air suspension must be turned off when
The electronically modulated air suspension must be turned off in the following situ-
ations as vehicle height may change due to the automatic leveling function, and, you
may catch part of your body in the vehicle and cause an accident, resulting in death
or serious injury.
●Any of the wheels is stuck in a ditch.
●It is necessary to jack up the vehicle.
●It is necessary to tow the vehicle with part of it lifted.
●When connecting/disconnecting a trailer
For safety, stop the engine if necessary.
■“HI” mode
●“HI” mode should only be used when driving on rough roads, for example when
driving off-road. Because the vehicle's center of gravity will become higher when
in the mode, the vehicle may become unstable when turning abruptly and cause
an accident, resulting in death or serious injury.
●Do not select “HI” mode when loading cargo on the roof luggage carrier.
Because the vehicle's center of gravity will become higher when in the mode, the
vehicle may become unstable when turning abruptly, and cause an accident,
resulting in death or serious injury.

■Flicker effect
When the camera is used under fluorescent light, sodium lights, or 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 result 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 images 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.
●Always check the vehicle surrounding area, because the guide lines are ancillary
lines.
●The guide lines are ancillary lines and do not change even if the steering wheel is
turned.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
●Do not use the system if the back door is open.

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
■TRC (Traction Control)
Helps to maintain drive power and prevent any of the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control
→P. 2 7 8
■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, 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.
■VSC+ (Vehicle Stability Control +) (if equipped)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance

When the VSC/TRC systems are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the VSC/TRC sys-
tems are operating.
■VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRC, 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-Crash Safety system) (if equipped)
→P. 2 8 0
■Emergency brake signal
In order to reduce the risk of a rear-end collision, when the brakes are
applied suddenly the stop lights will automatically flash to alert the vehicle
behind

Disabling the TRC/VSC systems
If the vehicle gets stuck in fresh snow or mud, the TRC/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 TRC system only
To turn the TRC 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 TRC and VSC systems
To turn the TRC and VSC systems
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.

■When the message is displayed on the multi-information display showing that
TRC has been disabled even if the VSC off switch has not been pressed
TRC and hill-start assist control cannot be operated. Contact your any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
■Sounds and vibrations caused by the ABS, VSC, TRC and brake assist
●A sound may be heard from the engine 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 TRC/VSC systems
Turning off the engine after turning off the TRC/VSC systems will automatically
reactivate them.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when vehicle
speed increases. However, when both TRC 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 input 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.
