“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

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 the “S”
position.
When driving in the “6” range within
the “S” position— Turn the “S” mode switch of the se-
lector to the “ −” side to select the “5”
range. The transmission will down-
shift to fifth range when the vehicle
speed drops down to or lower than
the following speed, and engine brak-
ing will be enabled. 5.7 L V8 (3UR

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
259 in this Section.
Turn the “S” mode switch of the selec-
tor to the “ −” side to select the “4”
range. The transmission will downshift
to fourth range when the vehicle speed
drops down to or lower than the follow-
ing speed, and stronger engine braking
will be enabled. 5.7 L V8 (3UR

When the cruise control is being
used, even if you downshift the
transmission, engine braking will not
be enabled because the cruise con-
trol is not cancelled. 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.
Turn the “S” mode switch of the selec-
tor 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 follow-
ing speed, and more powerful engine
braking than that of the “4” range posi-
tion will be enabled.

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 up1. 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.
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 516 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. To turn off: Push “TOW/HAUL” switch
once again and the “TOW/HAUL” mode
indicator light goes off.
“TOW/HAUL” mode is canceled by press-
ing “TOW/HAUL” switch again or by turn-
ing the ignition switch to “OFF”.
Even when “TOW/HAUL” mode is used
during normal driving, no damage is
caused to the engine or the transmission.
However, fuel economy is reduced and the
transmission and/or engine driving charac-
teristics may feel unusual.
Toyota recommends using “TOW/HAUL”
mode only when a heavy trailer or a large
heavy load is towed.

2412007 TUNDRA from Jul. ’07 Prod. (OM34463U)
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.
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.

2422007 TUNDRA from Jul. ’07 Prod. (OM34463U)
The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
When the ignition 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 under any speed or 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 the ordi-
nary 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 the 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 ignition switch is turned
to the “ON” position. If the indicator light
does not come on when the ignition 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 the time, the slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
it is no problem to continue driving.) The
system will be automatically restored after
a short time and the slip indicator light
goes off.XS17010a
TRACTION CONTROL OFF MODE
(twowheel drive mode only)
When getting the vehicle out of mud or
newly fallen snow, etc., it may be bene-
ficial to turn off the traction control
system. This system that controls en-
gine performance interferes with the
process of freeing rear wheels.
To turn off: Briefly push the “VSC OFF”
switch.
The “AUTO LSD” and slip indicator lights
will come on.
The vehicle stability control system is al-
ways activated, even if the traction control
system is turned off. To turn on: Briefly push the “VSC OFF”
switch once again.
The “AUTO LSD” and slip indicator lights
will go off.
If the engine is turned off while the
“AUTO LSD” and slip indicator lights are
on and then restarted, the indicator lights
will turn off automatically.
When you push and hold the “VSC OFF”
switch for 3 seconds or more with the
vehicle stopped, turn off the vehicle stabil-
ity control system. See “Vehicle stability
control system” on page 248 in this Sec-
tion.
“AUTO LSD” and slip indicator lights come
on for a few seconds when the ignition
switch is turned to the “ON” position. If
the indicator lights do not come on when
the ignition switch is turned to the “ON”
position, contact your Toyota dealer.
CAUTION
Do not drive with the traction control
system continuously turned off.
