■Situations unsuitable for dynamic radar cruise control with full-speed range
Do not use dynamic radar cruise control wi th full-speed range in any of the following
situations.
Doing so may result in inappropriate speed control and could cause an accident result-
ing in death or serious injury.
●Roads where there are pedestrians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as thos e covered with rain, ice or snow
●On steep downhills, or where there are sudden changes between sharp up and down
gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad enough that they may prevent the sensors from
detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the front surface of the radar sensor or camera sen-
sor
●In traffic conditions that require frequent repeated acceleration and deceleration
●When your vehicle is towing a trailer or during emergency towing

Pulling the lever toward you cancels
the speed control.
The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake
pedal does not cancel the setting.)
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
However, when a vehicle ahead is not dete
cted, cruise control does not resume when
the vehicle speed is approximately 25 mph (40 km/h) or less.
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehicle-
to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings may not occur even when the vehicle-to-
vehicle distance is small.
●When the speed of the preceding vehicle matches or exceeds your vehicle
speed
●When the preceding vehicle is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●When depressing the accelerator pedal

■When switching the vehicle height mode
Before lowering the vehicle height, check that there are no people under or around the
vehicle, and check for obstacles.
If you do not do this, body parts may be caught in the vehicle, possibly leading to an
accident.
■Using the high mode
The high 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, resulting in an acci-
dent.
■When jacking up the vehicle or installing tire chains
Turn off the height control and stop the engine, otherwise the vehicle height may
change due to the automatic leveling function and you may catch part of your body in
the vehicle, resultin g in an accident.
■When crossing rivers
Select the high mode and turn off the heig ht control. Drive at 30 km/h (18 mph) or
lower. Otherwise the vehicle height may change due to the automatic leveling function,
resulting in an accident.
■If your vehicle must be towed
Put the vehicle height in the normal mode and turn off the height control, otherwise the
vehicle height may change due to the automatic leveling function and you may catch
part of your body in the vehicle, resulting in an accident.
■If your vehicle becomes stuck in a ditch
Turn off the height control, otherwise the vehicle height may change due to the auto-
matic leveling function, re sulting in an accident.
■When loading cargo on the roof luggage carrier
Do not switch to high mode. Sudden steering could cause the vehicle to lose stability
due to the vehicle’s higher center of gr avity, possibly leading to an accident.

NOTICE
■When parking in areas with limited overhead height
After leaving the vehicle or unloading the luggage, the vehicle height may be slightly
higher than normal. Take care wh
en overhead height is limited.
■To avoid damage to the vehicle
●Normal mode will be switched to automatically even if the vehicle is started off in low
mode. Take care when over head height is limited.
●Do not select the low mode when driving on bumpy roads, as the underbody of the
vehicle may contact the road surface.
●When traveling on bumpy roads or through water, or when towing, turn off easy
access mode.
■Avoid rapid changes to the vehicle height
As the pump may overheat. Leave at a few seconds between selections when changing
the vehicle height mode.

■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load capac-
ity. In addition, make sure that the tires are inflated to the specified tire pressure level.
The Multi Terrain ABS, Active TRAC, VSC and Trailer Sway Control will not function
correctly if different tires are fitted on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modi fying the suspension will affect the driving
assist systems, and may caus e the system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations.
Depending on many factors such as the condit ions of the vehicle, trailer, road surface,
and driving environment, the Trailer Sway Co ntrol system may not be effective. Refer to
your trailer owner’s manual for information on how to tow your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may caus e death or serious injury.
●Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
●Begin releasing the accelerator pedal i mmediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize. ( P. 2 0 1 )
