■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON
mode (the engine is not running) for more than an hour with the shift lever in P, the engine
switch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI-
TION ON mode for long periods of ti me when the engine is not running.
■Operation of the engine switch
●When operating the engine switch, one short, firm press is enough. If the switch is
pressed improperly, the engine may not start or the engine switch mode may not
change. It is not necessary to press and hold the switch.
●If attempting to restart the engine immediat ely after turning the engine switch off, the
engine may not start in some cases. After turning the engine off, please wait a few sec-
onds before restarting the engine.

■When starting the engine
Always start the engine while
sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, re sulting in death or serious injury.
■Stopping the engine in an emergency
●If you want to stop the engine in an emergency while driving the vehicle, press and
hold the engine switch for more than 2 seco nds, or press it briefly 3 times or more in
succession. ( P. 5 1 5 )
However, do not touch the engine switch while driving except in an emergency. Turn-
ing the engine off while driving will not cause loss of steering or braking control, but
the power assist to these systems will be lost . This will make it more difficult to steer
and brake, so you should pull over and stop th e vehicle as soon as it is safe to do so.
●If the engine switch is operated while the vehicle is running, a warning message will be
shown on the multi-information display and a buzzer sounds.
●When restarting the engine after it was turn ed off while driving, shift the shift lever to
N and press the engine switch.

the engine switch is not off. When exiting the vehicle, always check that the engine
switch is off.
●Do not stop the engine when the shift lever is in a position other than P. If the engine is
stopped in another shift lever position, the engine switch will not be turned off but
instead be turned to ACCESSORY mode. If the vehicle is left in ACCESSORY
mode, battery discharge may occur.
■When starting the engine

■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 cause
the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the center
differential 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, th e vehicle height will not change.
Once the vehicle has been driven for a short 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 oper ating. 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 engine after off-road driving, the vehicle height may gradu-
ally lower. When parking, make sure ther e 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.
■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. Th is 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 displayed on the mu lti-information display, and the 4-Wheel
AHC cannot be activated until the malfunction 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 continue s to be displayed, have the vehicle checked
at your Lexus dealer as soon as possible.

■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.

■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 occur 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.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on. ( P. 5 2 4 , 5 3 2 )

■When using Crawl Control and Turn Assist function
Do not rely solely on the Crawl Control and Turn Assist function. This function does not
extend the vehicle’s performance limitations. Always thoroughly check the road condi-
tions, 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.
NOTICE
■When using Turn Assist function
The Turn Assist function is a function to assist turning performance when driving off
road. The function may be less effective on paved road surfaces.
