■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 time when the engine is not running.

■If the engine does not start
●Check that the shift lever is securely set in P. The engine may not start if the shift lever is
displaced out of P.
●The engine immobilizer system may not have been deactivated. ( →P. 77)
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
■Steering lock
After turning the engine switch off and opening and closing the doors, the steering wheel
will be locked due to the steering lock functi on. Operating the engine switch again auto-
matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, operation of the motor may be sus-
pended if the engine is turned on and off repeat edly in a short period of time. In this case,
refrain from operating the engine switch. After about 10 seconds, the steering lock
motor will resume functioning. “Steering Lock active” w ill be displayed on the

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 emer gency 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. 4 9 1 )
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause lo ss 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.

not running, the engine switch is not off. Exit the vehicle after turning the engine
switch 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 any authorized Lexus dealer or repair er, or another duly qualified and equipped
professional immediately.

To drive using temporary shift range selection, operate the “-” paddle shift switch.
When the “-” paddle shift switch is operated, the shift range will be downshifted
to a range that enables engine braking force that is suitable to driving conditions.
When the “+” paddle shift switch is operated, the shift range will be one gear
upper than the gear in use during normal D position driving. Changing the shift
range allows restriction of the highest gear, preventing unnecessary upshifting
and enabling the level of engine braking force to be selected.
Upshifting
Downshifting
The selected shift range, from D1 to D8,
will be displayed in the meter.
To return to normal D position driving,
the “+” paddle shift switch must be held
down for a period of time.
■Shift ranges and their functions
A lower shift range will provide greater engi ne braking forces than a higher shift
range.

To enter M mode, shift the shift lever to M. Gears can then be selected by oper-
ating the shift lever or paddle shift switches, allowing you to drive in the gear of
your choice.
Upshifting
Downshifting
The gear changes once every time the
shift lever or paddle shift switch is oper-
ated.
The selected gear, from M1 to M8, will
be fixed and displayed in the meter.
When in the M position, the gear will no t change unless the shift lever or pad-
dle shift switches are operated.
However, even when in the M position, the gears will be automatically
changed in the following situation:
●When vehicle speed drops (downshift only).
●When the automatic transmission fluid or engine coolant temperature is
low.
●When automatic transmission fluid temperature is high.
●When the needle of the tachometer is in the red zone (the range which
exceeds the allowable revs of the engine).
In the following situations, the gear will not shift even if the shift lever or paddle
shift switches are operated.
●“1st Gear not available due to slippery road surface” is displayed on the
multi information display.
●The vehicle speed is low (upshift only).

■Gear Shift Indicator function
●This function automatically operates during M mode.
●By following the Shift-up indicator and shifting up accordingly, it is possible
to achieve improved fuel economy and reduced exhaust emissions.
●The Gear Shift Indicator does not have a similar function for downshifting.
●Depending on the driving conditions, the Gear Shift Indicator may not dis-
play the Shift-up indicator while driving in M mode.
■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to a position other than D
■To protect the automatic transmission
“Transmission Fluid High Temperature” is di splayed on the multi-information display and
a function is adopted that automatically selects a higher shift range when the fluid tem-
perature is high. Have the vehicle inspected by any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
