2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
“1” (First range):
The gear is fixed in first regardless of
vehicle speed and driving conditions.
This range is to be used when maxi-
mum engine braking is necessary.
If you attempt to downshift the transmis-
sion when it is not possible to downshift
due to high vehicle speed, a warning tone
sounds twice.
NOTICE
Do not drive in the “3”, “2” or “1”
range when driving at high speed or
climbing a gentle slope for a long
time. Otherwise the transmission or
engine may overheat causing damage.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speed in each
range:

When the “S” mode indicator light does
not come on even with the selector lever
moved to the “S” position, there may be a
problem somewhere in the system. Have
your vehicle checked/repaired by your
Toyota dealer as soon as possible. In this
case, you can drive in the same condition
as in the “D” position.
(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
When driving in the “D” position—
Shift the selector lever to “S” position.
When driving in the “5” range within
the “S” position—
Move the selector lever down to the
“− ” side to select the “4” range. The
transmission will downshift to fourth
range and engine braking will be en-
abled.
When the cruise control is being used,
engine braking can not be enabled be-
cause the cruise control is not can-
celled. However, engine braking will be
automatically enabled if the vehicle
speed is higher than the set speed of
the cruise control depending on the
driving conditions. For decreasing the vehicle speed, see
“Cruise control” on page 262 in this
Section.
Move the selector lever down to the
“
− ” side to select the “3” range. The
transmission will downshift to third
range when the vehicle speed drops
down to or lower than the following
speed, and stronger engine braking will
be enabled.

(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:
On inclines, you can drive smoothly
with reduced shifting quantity. On de-
clines, the vehicle will shift down auto-
matically to obtain optimum engine
braking and reduce the driver ’s foot
braking load.
Automatic shifting point change con-
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 can be
changed in “S” mode. When the selec-
tor lever is in the “S” position, the
shift range position can be switched
between “6” (sixth range) and “1” (first
range) by shifting the selector lever to
the “+” (up) or “” (down) position. By
shifting the lever to the “+” (up) posi-
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 lever is
shifted to the “S” position, shift range
position “4” (fourth range) or “5” (fifth
range) is selected depending on the ve-
hicle speed.

221
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
“2” (Second range):
First or second gear will be selected
automatically according to the vehicle
speed and driving conditions. This
range is to be used when engine brak-
ing stronger than that of the “3” range
position is necessary.
“1” (First range):
The gear is fixed in first regardless of
vehicle speed and driving conditions.
This range is to be used when maxi-
mum engine braking is necessary.
If you attempt to downshift the transmis-
sion when it is not possible to downshift
due to high vehicle speed, a warning tone
sounds twice. Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
range:

(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
When driving in the “D” position—
Shift the selector lever to the “S”
position.
When driving in the “6” range within
the “S” position—
Move the selector lever down to the
“− ” side to select the “5” range. The
transmission will downshift to fifth
range and engine braking will be en-
abled.
Move the selector lever down to the
“ − ” side to select the “4” range. The
transmission will downshift to fourth
range and stronger engine braking will
be enabled.
When the cruise control is being used,
even if you downshift the transmission,
engine braking will not be enabled be-
cause the cruise control is not can-
celled. However, engine braking will be
automatically enabled if the vehicle
speed is higher than the set speed of
the cruise control depending on the
driving conditions. For ways to decrease the vehicle
speed, see “Cruise control” on page
262 in this Section.
Move selector lever down to the “
−”
side to select the “3” range. The trans-
mission will downshift to third range
when the vehicle speed drops down to
or lower than the following speed, and
more powerful engine braking than that
of the “4” range position will be en-
abled.

CAUTION
Be careful when downshifting on a
slippery surface. The abrupt change
in engine speed could cause the ve-
hicle to skid or spin.
(e) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(f) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.

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:
On inclines, you can drive smoothly
with reduced shifting quantity. On de-
clines, the vehicle will shift down auto-
matically to obtain optimum engine
braking and reduce the driver ’s foot
braking load.
Automatic shifting point change con-
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 can be
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 lever is
shifted to the “S” position, shift range
position “4” (fourth range) is selected
automatically.
However, if the selector lever is shifted
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.
