Driving WARNING ■
Situations unsuitable for dynamic rada r cruise control with full-speed range
Do not use dynamic radar cruise control with 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 pede strians, 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 fron t surface of the radar sensor or camera sen-
sor ●
In traffic conditions that require frequent repeated a cceleration and deceleration●
When your vehicle is towing a trailer or during emergency towing ●
When an approach warning buzzer is heard often

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 detected, 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 ma y 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 crui se control speed was set●
When depressing the accelerator pedalCanceling and resuming the speed control 1

To change the set speed, operate the leve r until the desired set speed is obtained.
Increases the speed
Decreases the speed Fine adjustment: Momentarily move the
lever in the desired direction.
Large adjustment: Hold the lever in the
desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By 1 mph (1.6 km/h)
* 1
or 1 km/h (0.6 mph)
* 2
each time the lever is
operated
Large adjustment: The set speed can be increased or decreased continually until the
lever is released.
* 1
: When the set speed is shown in “MPH”
* 2
: When the set speed is shown in “km/h”
Pulling the lever toward you cancels
the constant speed control. The speed setting is also canceled when
the brakes are applied.
Pushing the lever up resumes the
constant speed control. Resuming is available when the vehicle
speed is more than approximately 25
mph (40 km/h). ■
Cruise control can be set when ●
The shift lever is in the D or range 4 or higher of S has been selected. ●
Range 4 or higher has been selected by using the paddle shift. (vehicles with paddle
shift switches) ●
Vehicle speed is above approximately 25 mph (40 km/h). ■
Accelerating after setting the vehicle speed ●
The vehicle can be accelerated normally. After acceleration, the set speed resumes. ●
Even without canceling the cruise control, th e set speed can be increased by first accel-
erating the vehicle to the desired speed and then pushing the lever down to set the new

Driving ■
Automatic cruise control cancelation
Cruise control will stop main taining the vehicle speed in an y of the following situations:●
Actual vehicle speed falls more than appr oximately 10 mph (16 km/h) below the preset
vehicle speed.
At this time, the memorized set speed is not retained. ●
Actual vehicle speed is below approximately 25 mph (40 km/h).●
VSC is activated. ●
Active TRAC is activated for a period of time. ●
The switching operation continues for 5 seco nds or more after the center differential
lock switch has been operated. ●
When the VSC or Active TR AC system is turned off.■
If “Cruise Control Malfunction Visit Your Dealer” is shown on the multi-information
display
Press the “ON/OFF” button once to deactiv ate the system, and then press the button
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 the vehi-
cle inspected by your Lexus dealer.
WARNING ■
To avoid operating the cruise control by mistake
Switch the cruise control off using th e “ON/OFF” button when not in use.■
Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in loss of control and could cause an accident resulting in death or
serious injury. ●
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 hills
Vehicle speed may exceed the set speed when driving down a steep hill.●

Driving WARNING ■
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 ca ught 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, resulting in an accident. ■
When crossing rivers
Select the high mode and turn off the heig ht control. Drive at 18 mph (30 km/h) 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 vehi cle, 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 lu ggage, 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 overhead 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 throug h 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.
