the engine is turned on and off repeatedly in a short period of time. In this case,
refrain from operating the engine. After about 10 seconds, the steering lock motor
will resume functioning.

4-2. Driving procedures
To drive using temporary shift range selection, operate the “-” or “+” pad-
dle shift switch.
When the “-” paddle shift switch is oper ated, the shift range will be down-
shifted to a range that enables engine braking force that is suitable to driv-
ing conditions. When the “+” paddle shift switch is operated, the shift
range will be one gear upper than the gear in use during normal D posi-
tion driving.
Changing the shift range allows restriction of the highest gear, preventing
unnecessary upshifting and enabling th e level of engine braking force to
be selected.
Upshifting
Downshifting
6-speed models:
The selected shift range, from D1 to
D6, will be displayed in the meter.
8-speed models:
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 engine braking forces than a higher shift
range.

Driving
To enter M mode, shift the shift lever to M. Gears can then be selected by
operating the shift lever or paddle shif t switches, allowing you to drive in
the gear of your choosing.
Upshifting
Downshifting
The gear changes once every time the
shift lever or paddle shift switch is
operated.
6-speed models:
The selected gear, from M1 to M6, will
be fixed and displayed in the meter.
8-speed models:
The selected gear, from M1 to M8, will
be fixed and displayed in the meter.
When in the M position, the gear will not change unless the shift lever
or paddle 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 tempera-
ture 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 slippe ry road surface” is displayed on
the multi information display.
●The vehicle speed is low (upshift only).
■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 other than D
■To protect automatic transmission
When the temperature of the transmission fluid or engine oil becomes high, protec-
tion control is performed temporarily. Wh en “Transmission Fluid High Temperature”
is displayed on the multi-information display, have the vehicle inspected by your
Lexus dealer.
■Downshifting restrictions warning buzzer
To help ensure safety and driving perfor mance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driv-
ing in snow mode.
