Dynamic radar cruise control with full-speed range can be set when ●
The shift lever is in D or range 4 or higher of S has been selected.●
Range 4 or higher of D has been selected by using the paddle shift switch (vehicles with
paddle shift switches). ●
Vehicle speed is at or above approximately 30 mph (50 km/h).
However, when a preceding vehicle is detected, the dynamic radar cruise control with
full-speed range can be set even if the vehicle speed is below approximately 30 mph
(50 km/h). ■
Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle. ■
When the vehicle stops while follow-up cruising ●
Pushing the lever up while the vehicle ahead stops will resume follow-up cruising if the
vehicle ahead starts off within approximatel y 3 seconds after the lever is pushed up.●
If the vehicle ahead starts off within 3 seco nds after your vehicle stops, follow-up cruis-
ing will be resumed. ■
Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations: ●
Actual vehicle speed falls below approximately 25 mph (40 km/h) when there are no
vehicles ahead. ●
The preceding vehicle leaves the lane when yo ur vehicle is following at a vehicle speed
at or below approximately 25 mph (40 km/h). Otherwise, the sensor can not properly
detect the vehicle. (“CRUISE NOT AVAILA BLE No Preceding Vehi cles” is displayed
on the multi-information display) ●
VSC is activated. ●
Active TRAC is activated for a period of time. ●
When the VSC or Active TR AC system is turned off.●
When second start mode is set. ●
The sensor cannot detect correctly because it is covered in some way. ●
Pre-collision braking is activated. ●
The parking brake is operated. ●
The vehicle is stopped by system control on a steep incline. ●
The following are detected when the vehicle has been stopped by system control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes ●
The switching operation continues for 5 seco nds or more after the center differential
lock switch has been operated.
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in th e system. Contact your Lexus dealer.

In the following cases the 4-Wheel AHC will not operate●
The brake pedal has been depressed for a few seconds or longer while the vehicle is
stopped. ●
Vehicle height control has not been frequently used. ●
The suspension fluid temperature is lower than -22°F (-30°C). ●
There is ice on the suspension. ●
Driving on bumpy roads which may caus e the suspension to fully elongate.●
If the steering wheel is abrupt ly turned more than 3/4 of a revolution with the center dif-
ferential lock system activated. ■
Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid temperature
drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C). ●
In this case, even if the height select switch is pressed, the vehicle height will not change.
Once the vehicle has been driven for a sh ort time and the suspension fluid has been
warmed to within normal operating limits , the 4-Wheel AHC will begin operating and
the vehicle height will automatically change to the selected mode.●
When the suspension fluid is around -22°F (-30°C), the vehicle height may not be able
to be raised, even if the 4-Wheel AHC is operating. In this case, pull the height select
switch to “  ” then push to “  ” after driving for a short time longer to select the desired
vehicle height. ■
Parking and stopping tips ●
If you immediately stop the en gine after off-road driving, the vehicle height may gradu-
ally lower. When parking, ma ke sure there is nothing un der the vehicle that may come
in contact with the underbody. The vehicle will return to th e set height when the engine
is started. ●
The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started. ■
Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other than P
or N while the vehicle is stopped, you may hear a sound caused by the expansion and
contraction of the propeller shaft. This does not indicate a malfunction. ■
4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC , normal mode is automatically selected.
However, the system may not switch to norm al mode depending on the location of the
malfunction.
The warning message is displa yed on the multi-informatio n display, and the 4-Wheel
AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If the wa rning message turns off, the system is operat-
ing correctly. If the warning me ssage continues to be displayed, have the vehicle checked
at your Lexus dealer as soon as possible.

Driving assist systems ◆ Multi Terrain 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 su rface, or in off-road conditions (such as
rough roads, sand and mud)
◆ Brake assist Generates an increase d 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
◆ Active TRAC (Traction Control) Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippe ry roads, or in off-road conditions
◆ Hill-start assist control Helps to reduce the backward movement of the vehicle when starting on an incline or
slippery slope
◆ AVS (Adaptive Variable Suspension system) By independently controlling the damping force of the shock absorbers for each of
the 4 wheels according to th e road and driving conditions, this system helps riding
comfort with superior steering stabilit y, and helps good vehicle posture. When
SPORT S+ mode is selected by the drivin g mode select switch, the damping force is
suitable for sporty driving. (  P. 290)
◆ VGRS (Variable Gear Ratio Steering) Helps to adjust the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
◆ Trailer Sway Control Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine to rque when trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC turned off
or experiences a malfunction.To help enhance driving safety and perf ormance, the following systems oper-
ate automatically in response to variou s driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too heav-
ily when operating the vehicle.
