Driving
CAUTION
■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 resulting 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, resulting 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 seconds, or press it briefly 3 times or more in succes-
sion. ( →P. 511)
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.
NOTICE
■To prevent battery discharge
●Do not leave the engine switch in ACCESSORY or IGNITION ON mode for long
periods of time without the engine running.
●If the indicator on the engine switch is illuminated, 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
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehicle checked
by your Lexus dealer immediately.
■Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

GX 460 _O M_ OM6 0F 6 8U _(U )4-2. Driving procedures
Automatic transmission
While the engine switch is in IGNITION ON mode, move the shift lever
with the brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: Shifting to the D position allows the system
to select a gear suitable for the driving
conditions. Setting the shift lever to the D position is recommended for normal driv-
ing.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible gear ranges, controls engine braking forces, and prevents unnecessary upshifting.

■Dynamic radar cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle dis-
tance control mode has been used. The mode also cannot be switched from constant
speed control to vehicle-to-vehicle distance control mode. Turn the system off by press-
ing the “ON-OFF” button, and turn it on again.
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes. How-
ever, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease
below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following situ-
ations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are operating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
●When second start mode is set.
●Bad weather causes the detection function to become extremely unstable.
●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control driving is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.

■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 under 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 under 7 mph (12 km/h), height will not return to
LO mod e .
■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 mult i-information display, and the rear height
control air suspension 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 continues to be displayed, have your vehicle
inspected by your Lexus dealer as soon as possible.
