Driving
■When HI mode is selected
The vehicle height will change to N mode when driving at the speeds of 18 mph (30 km/h). 
Even if vehicle speed is then reduced to unde r 18 mph (30 km/h), height will not return to
HI mode.
■When LO mode is selected
The vehicle height will change to N mode when vehicle speed exceeds 7 mph (12 km/h). 
Even if vehicle speed is then reduced to unde r 7 mph (12 km/h), height will not return to
LO  m ode .
■Automatic leveling function
Regardless of the number of occupants and the luggage load, vehicle height in any mode
is always adjusted to a fixed height by the automatic leveling function.
■The rear height control air suspension  will not operate in the following cases:
●The underbody of the vehicle is touching the surface of the road.
●The area around the suspension is covered with ice.
■Even if you hear an operating noise
This does not indicate a problem in the rear height control air suspension.
■Parking and stopping tips
●If you immediately stop the engine after off- road driving, or park the vehicle for a long
time, the vehicle height may gradually lower.  When parking, make sure there is nothing
under the vehicle that may come in contact with the underbody. The vehicle will return
to the 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.
■When lowering the vehicle
In order to prevent the vehicle height from rising as occupants leave the vehicle, lowering
control will occur for a short while after the engine has been stopped.
■The rear height control air suspension failure warning
●If a malfunction occurs in the rear height  control air suspension, N mode is automati-
cally selected. However, the system may no t switch to N mode depending on the loca-
tion of the malfunction.
●The warning message is displayed on the multi-information display, and the rear height
control air suspension cannot be activated until the malfun ction is corrected.
Stop the engine and start it again. If the warning message turns off, the system is operat-
ing correctly. If the warning message contin ues to be displayed, have your vehicle
inspected by your Lexus deal er as soon as possible.

■When the Crawl Control system is operated continuously
This may cause the brake actuator to overheat. In this case, the Crawl Control system will
stop operating, a buzzer will sound, the Crawl 
Control indicator will turn off after flashing
and the “TRAC OFF” will be shown on the mult i-information display. In this case, quickly
stop the vehicle in a safe place and give the  actuator adequate time to cool off. Refrain
from using the system until the message goes  off. (The vehicle can be driven normally
during this time.)
■If the automatic transmission system overheats
The system will cease operation, a buzzer will sound and a warning message will be dis-
played to alert the driver. Stop the vehicle in  a safe place until the warning message turns
off. ( P.  5 2 5 )
■Sounds and vibrations caused by the Crawl Control system
●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 Crawl Control system.
●Either of the following conditions may occu r when the Crawl Control system is operat-
ing. None of these are indicators  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.
■If the slip indicator comes on...
It may indicate a malfun ction in the system. Consult your Lexus dealer.
CAUTION
■When using Crawl Control
Do not rely solely on the Crawl Control. This function does not extend the vehicle’s
performance limitations. Always thoroughly  check the road conditions, and drive
safely.
■These conditions may cause the system not to operate properly
When driving on the following surfaces, the sy stem may not be able to maintain a fixed
low speed, which may re sult in an accident:
●Extremely steep inclines.
●Extremely uneven surfaces.
●Snow-covered roads, or other slippery surfaces.

PCS (Pre-Collision system)
◆Pre-collision seat belts (front seat belts only)
If the system detects that a collision is 
unavoidable, the system will retract the
seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. ( P.  2 9 )
However, when the VSC system is disabled, the system will not operate in the
event of skidding.
◆Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to ho w strongly the brake pedal is depressed.
◆Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning di splay and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collisio n braking can be disabled using the
pre-collision braking off switch.
◆AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion, the AVS optimizes the damping effect ( P.  3 3 5 )
: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-colli-
sion system such as the brakes and seat belts are automatically engaged to
lessen impact as well as vehicle damage.

◆Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision with the
vehicle in front, and the driver is not facing forward, PCS warnings are given in
advance to warn the driver. If the driv er continues to not be facing forward,
and a high possibility of a collision with the vehicle in front is detected, PCS
informs the driver of high possibility of a collision with the vehicle in front by
performing slight braking to provide a physical warning (pre-collision alert
braking).

■Automatic cancelation of pre-collision system
When a malfunction occurs due to sensor cont
aminations, etc. that results in the sensors
being unable to detect  obstacles, the pre-collision syst em will be automatically disabled.
In this case, the system will not activate  even if there is a collision possibility.
■Obstacles not detected
The system cannot detect plastic obstacles su ch as pylons. There may also be occasions
when the system cannot detect pedestrians, animals, bicycles, motorcycles, trees, or
snowdrifts.
■Conditions that may trigger the system even  if there is no possibility of a collision
In any of the following situations where the fr ontal area of the radar sensor is interrupted,
the radar sensor may detect possibility of a fr ontal collision and the system may be acti-
vated.
●When passing by an oncoming vehicle in a  curve or a turn to the right or the left
●When rapidly approaching an obstacle ahead  (e.g. preceding vehicle, toll gate barrier,
etc.)
●When there is a structural ob ject (billboard, low ceiling, fluorescent light, etc.) above
the uphill road ahead
●When driving on a narrow road or through under a low overhead structure (bridge,
tunnel, fly-under, etc.)
●When driving on an uneven road surface
●When there is a metal object, bump, or protrusion on the road surface
●When vehicle’s front part is raised or  lowered depending on loading conditions
●When the direction of radar sensor is misa ligned by strong impact applied on an area
around the radar sensor, etc.
●When there is an obstacle (guard rail, etc.)  by the roadside at the entrance to a curve
●When the front of your vehicle is pointing upwards (caused by towing a trailer, during
emergency towing or putting a heavy load in the luggage compartment etc.)
When the system is activated in the situations  described above, there is also a possibility
that the seat belts will retract  quickly and the brakes may be applied with a force greater
than normal. When the seat belt is locked in  the restricted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■When there is a malfunction in the system,  or if the system is temporarily unusable
Warning lights will turn on or flash, an d warning messages will be displayed.

CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used.
●Use snow tires on all, not just some wheels.
●Do not use LDA (Lane Departure Alert) system. (if equipped)
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle  being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used, or 30
mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, ab rupt steering, sudden braking and shifting operations
that cause sudden engine braking.
●Slow down sufficiently before entering a cu rve to ensure that vehicle control is main-
tained.
●Do not use LDA (Lane Departure Alert) system. (if equipped)
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of the
tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when tire
chains are fitted.

■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power radio
transmitter and receiver. It receives  and also sends out radio frequency (RF)
signals.
In August 1996, the Federal Communications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safe ty standards previously set by the fol-
lowing U.S. and international standards bodies.
●ANSI (American National Stan dards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
●ICNIRP (International Commission on  Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over  120 scientists, engineers, and physi-
cians from universities, and governme nt health agencies and industries
reviewed the available body of research to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards.
