(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 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) or “5” (fifth
range) is selected depending on the ve-
hicle speed.

Turn the “S” mode switch of the selec-
tor to the “−” side to select the “2”
range. The transmission will downshift
to second range when the vehicle
speed drops down to or lower than the
following speed, and more powerful en-
gine braking will be enabled.

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.

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(g) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
shift the selector lever into “S” posi-
tion.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the transmission in “D”. Select an
appropriate shift range in “S” mode.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
(h) If you cannot shift the selector le-
ver out of “P” position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift automatic transmission
selector lever” on page 522 in Section 4.

(i) “TOW/HAUL” switch (on some models)
Use “TOW/HAUL” mode when pulling a
trailer or hauling a heavy load. In this
mode, the driving and engine braking per-
formance is improved in accordance with
towing conditions or increased load.
To turn on: Push “TOW/HAUL” switch
“TOW/HAUL” mode is activated and
“TOW/HAUL” mode indicator light comes
on by pressing “TOW/HAUL” switch.

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
CAUTION
Never operate the front drive control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
To shift from “4H” to “2WD”, reduce the
vehicle speed to less than 100 km/h (62
mph) and turn the front drive control
switch knob fully counterclockwise.
When you operate the front drive control
switch knob from “4H” to “2WD” with the
vehicle speed at 100 km/h (62 mph) or
higher, the “4HI” indicator light continues
to blink and buzzer sounds. When the
switch knob is returned from “2WD” to
“4H”, the indicator light turns off and the
buzzer stops sounding.
If the “4HI” (high speed four −wheel drive)
indicator light continues to blink when you
operate the front drive control switch knob
from the “4H” to the “2WD” position, this
reminds you that the transfer mode is not
securely in “2WD” mode. Drive straight
ahead while accelerating or decelerating,
or drive forward or backward for a short
distance. If there is any malfunction within the
brake system, “4HI” or “4LO” indicator
light blinks and the transfer mode may not
be able to be shifted from “4H” to “2WD”.
If the indicator light continues to blink
even if doing so, contact your Toyota
dealer as soon as possible. There may be
a trouble in the four
−wheel drive system.
CAUTION
Never operate the front drive control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
SHIFTING BETWEEN “4H” AND “4L”
To shift between “4H” and “4L”
1. Bring the vehicle to a complete stop with the brake pedal held down.
2. Shift the automatic transmission selec- tor lever into “N”.
3. To shift from “4H” to “4L”, push and turn the front drive control switch knob
fully clockwise.
To shift from “4L” to “4H”, turn the
front drive control switch knob counter-
clockwise. 4. Maintain this condition until the “4LO”
or “4HI” indicator light comes on.
If the “4LO” indicator light continues to
blink...
If this indicator light continues to blink
when you operate the front drive control
switch knob to the “4H” or “4L” position,
stop the vehicle completely, shift the auto-
matic transmission selector lever securely
into “N” and operate the switch knob
again.
INFORMATION
 If the engine coolant temperature is
too low the transfer mode may not
be able to be shifted. When the en-
gine is warmer operate the switch
knob again.
 If the automatic transmission selec-
tor lever is moved before the indi-
cator comes on, the transfer mode
may not be shifted completely. In
this case, stop the vehicle com-
pletely, return the automatic trans-
mission selector lever to “N” and
operate the switch knob again.

243
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
If there is any malfunction in the brake
system or the engine, “4HI” or “4LO” indi-
cator light blinks and the transfer mode
may not be able to be shifted from “4H”
to “4L”.
If the indicator continues to blink even if
doing so, contact your Toyota dealer as
soon as possible. There may be a trouble
in the four−wheel drive system. The traction control system automatical-
ly helps prevent the spinning of the
rear wheels (twowheel drive models)
or 4 wheels (fourwheel drive models)
when the vehicle is started or acceler-
ated on slippery road surfaces.
When the engine switch is turned to the
“ON” position, the system automatically
turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle at any speed or in maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.

NORMAL DRIVING MODE
Leave the system on during ordinary
driving so that it can operate when
needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in self−check mode,
but does not indicate a malfunction.
When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels (two −wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator light
blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to the “ON” position. If the indicator light
does not come on when the engine switch
is turned on, contact your Toyota dealer. The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.
Traction control system
“AUTO LSD” system
If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no l onger operate. In this
case, immediately stop your vehicle at a
safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At this time, the slip indicator light comes
on and the traction control system tempo-
rarily stops operating in order to protect
the brake actuator. (Although the traction
control system does not operate, it is not
a problem to continue driving.) The sys-
tem is automatically restored after a short
time and the slip indicator light goes off.XS17010a
and only one of the rear wheels be-
gins to spin,which also may the rear
wheels.TRACTION CONTROL OFF MODE
(twowheel drive mode only)
When getting the vehicle out of mud or
snow, etc., and only one of the rear
wheels begins to spin, it may be benefi-
cial to turn off the traction control sys-
tem. This system which also controls
engine performance may interfere with
the process of freeing the rear wheels.

The “VSC OFF” indicator light flashes
and the slip indicator light comes on
The “VSC OFF” indicator light flashes and
the slip indicator light comes on to warn
that there is a problem somewhere in the
following:
Traction control system
Vehicle stability control system
“AUTO LSD” system
When the system is normal and the engi-
ne switch is turned to the “ON” position,
the lights will come on and go off after a
few seconds.
If the “VSC OFF” indicator light flashes
and the slip indicator light comes on dur-
ing driving, the traction control system will
not work. However, because the brakes
operate normally when applied, it is not a
problem to continue driving.
In the following cases, contact your Toyota
dealer:
The “VSC OFF” and slip indicator lights
do not come on after the engine switch
is turned to the “ON” position.
The “VSC OFF” indicator light flashes
and the slip indicator light remains on
after the engine switch is turned to the
“ON” position.
The “VSC OFF” indicator light flashes
and the slip indicator light comes on
during driving.
XS17009
The “AUTO LSD” system aids traction
by using the traction control system to
control engine performance and braking
when only one of the rear wheels be-
gins to spin.
This system should be used only when
wheel spinning occurs in a ditch or
rough surface.
This system is effective when only one of
the rear wheels is spinning.
