Selecting shift ranges in the D position
To drive using temporary shift range selection, operate the “-” shift paddle
switch. The shift range can then be selected by operating the “-” and “+”
shift paddle switches. Changing the shift range allows restriction of the
upper limit of the gears to be used , preventing unnecessary upshifting
and enabling the level of engine braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1 to
6, will be displayed in the meter
cluster.
To return to normal D position
driving, the “+” shift paddle switch
must be held down for a period of
time.
■ Selecting a driving mode
The following patterns can be selected to suit current driving and
operating conditions.
Power mode
For powerful acceleration
and driving in mountainous
regions.
Normal mode
Snow mode
For accelerating and driving
on slippery road surfaces,
such as on snow.
Press “SNOW”
to return to nor-
mal mode.

Changing shift ranges in S modeTo enter S mode, shift the shift lever to the S position. The shift range can
then be selected by operating the “-” and “+” shift paddle switches or the
shift lever. Changing the shift range a llows restriction of the upper limit of
the gears to be used, preventing unnecessary upshifting and enabling the
level of engine braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1 to
6, will be displayed in the meter
cluster.
The initial shift range in S mode is automatically set to 5 or 4 according to
vehicle speed. However, the initial shift range may be set to 3 or 2 if the
AI-SHIFT has operated while the sh ift lever was in the D position.

■When the “-” shift paddle switch is operated in the D position
When the “-” shift paddle switch is operated in the D position, a shift range will be
automatically selected. The highest gear of the first shift range will be one gear
lower than the gear in use during normal D position driving.
■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
●When range 6 is selected and the accelerator pedal is depressed
●If the accelerator pedal is depressed for more than a certain period of time
■To protect automatic transmission
A function is adopted that automatically selects a higher shift range when the fluid
temperature is high.
■Gear position display when driving
The current gear is displayed on the multi-information display. (→P. 1 6 3 )
■Downshifting restrictions warning buzzer
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or shift paddle switch is operated. (The warning buzzer will
sound twice.)
■When driving with the cruise control system or dynamic radar cruise control sys-
tem
Engine braking will not occur during shift range selection in the D position or S
mode, even when downshifting to range 5 or 4. ( →P. 175, 179)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned off after driving in snow mode.
