CAUTION
■If a safety system warnin
g light does not come on
Should a safety system light such as th e ABS/Multi Terrain ABS and the SRS warning
light not come on when you start the engine, this could mean that these systems are not
available to help protect you in an accide nt, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.

GX460_OM_OM60Q84U_(U)4-1. Before driving
●Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Apply the parking brake firmly, and put the transmission in P.
Avoid parking on a slope, but if unavoidable, do so only after performing the
following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and trailer’s
wheels.
When the wheel blocks are in place, release the brakes slowly until the
blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
●When restarting afte r parking on a slope:
With the transmission in P, start the en gine. Be sure to keep the brake pedal
pressed.
Shift into 3, 2, L, or R (if reversing).

CAUTION
■Before using dynamic
radar cruise control
Do not overly rely on vehicle- to-vehicle distance control.
Be aware of the set speed. If automatic de celeration/acceleration is not appropriate,
adjust the vehicle speed, as well as the distance between your vehicle and vehicles
ahead by applying the brakes etc.
■Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure following distance
The dynamic radar cruise control is only in tended to help the driver in determining
the following distance between the driver ’s own vehicle and a designated vehicle
traveling ahead. It is not a mechanism that allows careless or inattentive driving, and it
is not a system that can assist the driver in low-visibility conditions . It is still necessary
for driver to pay close attention to the vehicle’s surroundings.
●Assisting the driver to judg e proper following distance
The dynamic radar cruise control determines whether the following distance
between the driver’s own vehicle and a designated vehicle traveling ahead is appro-
priate or not. It is not capab le of making any other type of judgement. Therefore, it is
absolutely necessary for the driver to remain vigilant and to determine whether or not
there is a possibility of danger in any given situation.
●Assisting the driver to operate the vehicle
The dynamic radar crui se control has no capability to prevent or avoid a collision with
a vehicle traveling ahead. Therefore, if there is ever any danger, the driver must take
immediate and direct control of the vehicle and act appropriately in order to ensure
the safety of all involved.

●The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-
tion to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi
als that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility th at the obstacle will come within the sensor’s detection
areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sens or may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of the air conditioning system.
■If a message is displayed on the multi-information display
 P. 528
■Certification for the intuitive parking assist (Canada only)
This ISM device complies with Canadian ICES-001.
■Customization
Settings (e.g. buzzer sounds volume) can be changed.

Driving assist systems
◆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
◆Multi Terrain ABS (Anti-lock Brake System) (vehicles with a Multi-terrain
Select 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)
The Multi Terrain ABS operates in synchr onization with the Multi-terrain Select
◆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
◆TRAC (Traction Control) for H4 position
Helps to maintain drive power and prevent the drive wheels from spinning when start-
ing the vehicle or accelera ting on slippery roads
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.

■Sounds and vibrations caused by the AB
S/Multi Terrain ABS, brake assist, TRAC/
Active TRAC, VSC/Trailer Sway Control and hill-start assist control systems
●A sound may be heard from the engine compartment when the engine is started or just
after the vehicle begins to move. This soun d 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 operating.
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 afte r the vehicle comes to a stop.
• The brake pedal may pulsate slightly afte r the ABS/Multi Terrain ABS is activated.
• The brake pedal may move down slightly after the ABS/Multi Terrain ABS is acti-
vated.
■Reactivation of the TRAC or Active TR AC/VSC/Trailer Sway Control systems after
turning off the engine
Turning off the engine after turning off the TRAC or Active TRAC/VSC/Trailer Sway
Control systems will automatically re-enabled them.
■Reactivation of the TRAC or Active TRAC system linked to vehicle speed
When only the TRAC or Active TRAC system is turned off, the TRAC or Active TRAC
system will turn on when vehi cle speed increases. However, when both TRAC or Active
TRAC and VSC/Trailer Sway Control systems ar e turned off, the systems will not turn on
even when vehicle speed increases.
■When the brake system operates continuously
The brake actuator may overheat . In this case, the TRAC or Active TRAC and hill-start
assist control systems will stop operating, a buzzer will sound and the “TRAC OFF” will
be shown on the multi-information display. Refrain from using the system until the mes-
sage goes off. (There is no proble m with continuing normal driving.)
■If the slip indicator comes on...
It may indicate a malfunction in the TRAC /Active TRAC, VSC/Trailer Sway Control or
hill-start assist control system. Consult your Lexus dealer.
■KDSS
Some difference of vehicle height between left and right side can appear. This does not
indicate a malfunction in the KDSS system. For more information, contact your Lexus
dealer.
