“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see Section 3.
“ON”—Engine on and all accessories
on.
This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key. “LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the key
from “ACC” to the “LOCK” position. On
vehicles with an automatic transmission,
the selector lever must be in the “P” posi-
tion before pushing the key.
Once you remove the key, the engine im-
mobilizer system is automatically set. (See
“Engine immobilizer system” in Section
1
−2.)
When starting the engine, the key may
seem stuck at the “LOCK” position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.
Approximately five hours after the engine
is turned off, you may hear sound coming
from underneath the rear deck for several
minutes. This is normal operation and
does not indicate a malfunction. (See
“Leak detection pump”.)
It is not a malfunction if the needles on
all meters and gauges move slightly when
the key is turned to the “ACC”, “ON” or
“START” position.
CAUTION
For manual transmission:
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
ignition could be damaged.

2006 TUNDRA from Oct. ’06 Prod. (OM 34458U)
Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of “P” position when the
brake pedal is depressed (with the ignition
switch in “ON” or “ACC” position and the
selector lever pulled toward you).
(a) Selector lever
The shift position is displayed on the in-
strument cluster.
P:Parking, engine starting and key
removal

(c) Overdrive switch
You can select either fourth gear (with
overdrive off) or fifth gear (with overdrive
on) by pushing this switch.
To turn the overdrive off, push the switch.
The “O/D OFF” indicator light should come
on. To turn the overdrive on again, push
the switch again. The “O/D OFF” indicator
light should go off.
Always drive your vehicle with the over-
drive on for better fuel economy and
quieter driving.
If the engine is turned off when the over-
drive is off and restarted, the overdrive
will automatically be on. Vehicles with cruise control—When the
cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be enabled because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” in this Section.
(d) Normal driving
1. Start the engine as instructed in “How to start the engine” in Section 3. The
transmission must be in “P” or “N”.
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 turn the overdrive on for better
fuel economy and quieter driving. If the
engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive on.
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.
(e) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The “O/D
OFF” indicator light will come on and
the transmission will downshift to third
gear.
Shift into the “3” position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled. Tw o −wheel drive models

cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be enabled because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” in this Section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(f) Using “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “3”, “2” or
“SHIFT L” switch depressed, the vehicle
can move just as if the lever was in “D”.
With the selector lever in “3”, “2”, the
vehicle will start in first gear and automat-
ically shift to second gear.
With the “SHIFT L” switch depressed, the
transmission is engaged in first gear.
NOTICE

Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:

 Do not continue hill climbing or
hard towing for a long time in the
“3”, “2” or “L” position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, “D” position
should be used in hill climbing or
hard towing.(g) 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.
(h) 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.
(i) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and ov-
erdrive when climbing a gentle slope,
the overdrive should be turned off. Be
sure to turn the switch on immediately
afterward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
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.

The shift pattern is as shown above.
In case of driving your vehicle, the buzzer
will sound when you shift the gear into
“R” (reverse).
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving,
because it will cause clutch trouble. Do
not use the clutch to hold the vehicle
when stopped on an uphill grade—use the
parking brake. Recommended shifting speeds
The transmission is fully synchronized and
upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the following
speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
5 to 6 or 6 to 5 80 (50)
Downshift to the appropriate gear if accel-
eration is needed when you are cruising
below the above downshifting speeds.
Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption. 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
gear:
gear km/h (mph)1 45 (28)
2 90 (56)
3 130 (81)
4 165 (112)
NOTICE
Do not downshift if you are going
faster than the maximum allowable
speed for the next lower gear.

Good driving practice
If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use sixth gear.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
NOTICE
Do not use any gears other than
first gear when starting off and
moving forward. Doing so may dam-
age the clutch.
 Make sure the vehicle is completely
stopped before shifting into reverse.
Use the “2WD/4HI” and “4LO” switches
to select the following transfer modes.
1. “2WD” (high speed position, two wheel drive): “2WD/4HI” and “4LO”
switches left out
Use this for normal driving on dry,
hard− surfaced roads. This position
gives greater economy, the quietest
ride and least wear.
2. “4HI” (high speed position, four wheel drive): “2WD/4HI” switch pushed
in
The “4HI” indicator light comes on
when the “4HI” mode is selected.
Use this for normal driving on wet, icy
or snow −covered roads. This position
provides greater traction than two−
wheel drive.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.)

3. “4LO” (low speed position, four
wheel drive): With the “2WD/4HI”
switch pressed in, push the “4LO”
switch
The “4LO” indicator light comes on
when the “4LO” mode is selected.
Use this for maximum power and trac-
tion. Use “4LO” mode for climbing or
descending steep h ills, off−road driving,
and hard pulling in s and, mud or deep
snow.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.)
See “(c) Shifting procedure” for further
instructions. 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 “4HI”
To shift from “2WD” to “4HI”,
reduce
the vehicle speed to less than 100 km/h
(62 mph) and push in the “2WD/4HI”
switch.
If the “4HI” indicator light flashes when
you push in the “2WD/4HI” switch, this
reminds you that the transfer mode is not
securely in “4HI” mode. Drive straight
ahead while accelerating or decelerating.
If the “4HI” indicator light flashes and the
buzzer sounds when you push in the
“2WD/4HI” switch, this reminds you that
the transfer mode is not in “4HI” mode.
Reduce the vehicle speed to less than
100 km/h (62 mph). Push the switch to
turn it off, then once again to turn it back
on.
CAUTION
Never push the “2WD/4HI” switch if
the wheels are slipping. Stop the slip-
ping or spinning before shifting.
