(b) Normal driving
1. Start the engine as instructed in "How
to start the engine" on page 474 in
Section 3. The transmission must be in
"P" or "N".
When the front drive control switch knob
is in "4L" (low−speed position, four−wheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
"Four−wheel drive system" on page 240 in
this Section for information of the front
drive control lever.)
2. With your foot holding down the brake
pedal, shift the selector lever to "D".
When the lever is in the "D" position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
Always use the "D" position for better fuel
economy and quieter driving. If the engine
coolant temperature is low or when the
front drive control switch knob is in "4L"
(low−speed position, four−wheel drive), the
transmission will not shift into the over-
drive gear even in the "D" position. (See
"Four−wheel drive system" on page 240 in
this Section for information of the front
drive control.)
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
AI (Artificial Intelligence) shifting con-
trol—
AI shifting control selects the most
suitable shift range automatically ac-
cording to the driver's operation and
driving condition.
AI shifting control operates automatical-
ly with the selector lever in the "D"
position. When the lever is moved to
the "S" position, this function will be
cancelled.
Shifting control on the slope:
D
On inclines, you can drive smoothly
with reduced shifting quantity. On de-
clines, the vehicle will shift down auto-
matically to obtain optimum
braking and reduce the driver's foot
braking load.

trol:
The most suitable shift range is se-
lected depending on the driver's accel-
erator pedal operation and vehicle con-
dition.
(c) Driving in "S" mode
The shift range position
changed in "S" mode. When the selec-
tor lever is in the "S" position, the
shift range position can be switched
between "5" (fifth range) and "1" (first
range) by turning the "S" mode switch
of the selector lever to the "+" (up) or
"−" (down) direction. By turning the
"S" mode switch to the "+" (up) direc-
tion and holding it for at least 1 sec-
ond, the highest shift range position
can be obtained. However, it cannot be
changed while cruise control is acti-
vated. When the selector
shifted to the "S" position, shift range
position "4" (fourth range) is selected
automatically.
However, if the selector lever is shifted
engine
to the "S" position when AI shifting
control is being performed, the initial
shift range position may be "3" (third
range). This is because the suitable
shift range is selected depending on
the driving condition.
