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 “POWER ON” is displayed on the multi-information display, 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 repairer, or another duly qualified
and equipped professional 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 malfunction. Contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional

To drive using temporary shift range selection, operate the “-” or “+” pad-
dle shift switch.
When the “-” paddle shift switch is operated, 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 the level of engine braking force to
be selected.Upshifting
Downshifting
The selected shift range, from D1 to
D6, 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.

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 slippery road surface” is displayed on
the multi information display.
●The vehicle speed is low (upshift only).
