2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
(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.

(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.

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

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.

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—
Turn the “S” mode switch of the selec-
tor lever to the “−” side to select the
“4” range. The transmission will down-
shift to fourth range and engine braking
will be enabled.
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.
Turn the “S” mode switch of the selec-
tor lever to the “
−” side to select the
“3” range. The transmission will down-
shift to third range when the vehicle
speed drops down to or lower than the
following speed, and stronger engine
braking will be enabled.

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal once again.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control is designed to main-
tain a set cruising speed without requir-
ing the driver to operate the accelera-
tor. Cruising speed can be set to any
speed above 40 km/h (25 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Be careful about vehicle speed as
it may increase when driving down-
hill with the cruise control on.

TURNING THE SYSTEM ON AND OFF
To turn the cruise control on, press the
“ON−OFF” button. The “CRUISE” indicator
light on the instrument panel will come on
to indicate that the cruise control is opera-
tional. Pressing the “ON −OFF” button
again turns the system off.
When the system is turned off, cruising
speed must be reset when the cruise con-
trol is turned on again.
When the engine switch is turned off, the
system is also automatically turned off. To
use the cruise control again, press the
“ON −OFF” button again to turn it on.

SETTING THE CRUISING SPEED
5−speed models—The transmission must
be in the “D” position or the shift range
position must be in “4” (fourth range) or
“5” (fifth range) in “S” mode before you
set the cruising speed.
6 −speed models—The transmission must
be in the “D” position or the shift range
position must be in between “4” (fourth
range) and “6” (sixth range) in “S” position
before you set the cruising speed. Bring your vehicle to the desired speed,
push the lever down in the “
−SET” direc-
tion and release it. This sets the vehicle
at that speed. If the speed is not satisfac-
tory, tap the lever up for a faster speed,
or tap it down for a slower speed. Each
tap changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot off
the accelerator pedal.
If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE CRUISE CONTROL
The cruise control may be temporarily
cancelled by the driver or by the system
itself under certain circumstances. Tempo-
rary cancellation allows the set cruising
speed to remain in memory.
The cruise control can be temporarily can-
celled by doing the following:
Pulling the lever in the “CANCEL” di-
rection and releasing it
Depressing the brake pedal
Under certain circumstances, the cruise
control is temporarily cancelled:
