TOYOTA TUNDRA 2007 2.G Owners Manual

2322007 TUNDRA from Jul. ’07 Prod. (OM34463U)
(b) Normal driving1. Start the engine as instructed in “How to start the engine” on page 468 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 239 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 239 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.

2332007 TUNDRA from Jul. ’07 Prod. (OM34463U)
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 “2” (second
range) or “3” (third range). This is be-
cause the suitable shift range is se-
lected depending on the driving condi-
tion.
The “S” mode indicator light and the cur-
rent shift range position are shown on the
instrument cluster.

Shift range positions
“6” (Sixth range):
The most suitable gear is selected au-
tomatically between first and overdrive
(sixth) gears according to the vehicle
speed and driving conditions.
“5” (Fifth range):
The most suitable gear is selected au-
tomatically between first and fifth gears
according to vehicle speed and driving
conditions. This range is suitable for
acceleration such as when you want to
pass a vehicle running ahead of you
during high speed driving.
“4” (Fourth range):
The most suitable gear is selected au-
tomatically between first and fourth
gears according to the vehicle speed
and driving conditions. Slight engine
braking will be obtained on a downhill
road. Smooth running with less shifting
will be obtained on an uphill road.
“3” (Third range):
The most suitable gear is selected au-
tomatically between first and third
gears according to the vehicle speed
and driving conditions. This range is to
be used when stronger engine braking
is necessary.

2342007 TUNDRA from Jul. ’07 Prod. (OM34463U)
“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:

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.

Use the front drive control switch knob
to select the following transfer modes.
“2WD” (high speed position, twowheel
drive): Front drive control switch knob at
“2WD”
Use this for normal driving on dry hard −
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
“4H” (high speed position, fourwheel
drive): Front drive control switch knob at
“4H”
The “4HI” (high speed four −wheel drive)
indicator light comes on when the “4H”
mode is selected.
Use this for greater traction than two−
wheel drive. (When you experience a loss
of power, such as wheel spinning.) This
position provides greater traction than
two −wheel drive.
In this mode, the vehicle stability control
system is off. (See “Vehicle stability
control system” on page 248 in this
Section.)
“4L” (low speed position, fourwheel
drive): Front drive control switch knob at
“4L” The “4LO” (low speed four
−wheel drive)
indicator light comes on when the “4L”
mode is selected.
Use this for maximum power and traction.
Use “4L” position for climbing or descend-
ing steep hills, off −road driving, and hard
pulling in sand, mud or deep snow.
See “(c) Shifting procedure” for further in-
structions.
In this mode, the vehicle stability control
system is off. (See “Vehicle stability
control system” on page 248 in this
Section.)
Fourwheel drive system
(a) Front drive control

2402007 TUNDRA from Jul. ’07 Prod. (OM34463U)
The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in “(c) Shifting procedure”.
You should drive in four−wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated. SHIFTING BETWEEN “2WD” AND “4H”
To shift from “2WD” to “4H”,
reduce the
vehicle speed to less than 100 km/h (62
mph) and turn the front drive control
switch knob fully clockwise.
When the ambient temperature is −15 C
(5.0 F) or lower, shifting can be performed
with the vehicle speed below 70 km/h (43
mph).
If the “4HI” (high speed four −wheel drive)
indicator light continues to blink when you
operate the front drive control switch knob
from the “2WD” to the “4H” position, this
reminds you that the transfer mode is not
securely in “4H” mode. Drive straight
ahead while accelerating or decelerating.
If the “4HI” (high speed four −wheel drive)
indicator light continues to blink and the
buzzer sounds when you operate the front
drive control switch knob from the “2WD”
to the “4H” position, this reminds you that
the transfer mode is not in “4H” mode.
Stop the vehicle or reduce the vehicle
speed to less than 100 km/h (62 mph).
(When the ambient temperature is −15 C
(5.0 F) or lower, it needs to be reduced
to below 70 km/h (43 mph).) Operate the
switch knob again.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 in a short
distance.
(b) A.D.D. (automatic
disconnecting differential) (c) Shifting procedure

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.
