Shift into the “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.

2UZ− FE engine
“2WD” or “4HI” mode is selected 36 km/h (22 mph)
“4LO” mode is selected 14 km/h (8 mph) 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.
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 over −rev 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
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” (high speed four −wheel
drive) 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.)
Four −wheel drive system—
(a) Front drive control

2005 TUNDRA from Aug. ’04 Prod. (OM34427U)
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 key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer. The brake actuator temperature increases
during the traction control system, vehicle
stability control system or “AUTO LSD”
system operating. If the brake actuator
temperature becomes too high while any
of the systems is operating, a buzzer will
start to sound intermittently to indicate
that the traction control system can no
longer 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.

“VSC TRAC” warning light
This light warns 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 igni-
tion key is turned to “ON”, the light will
come on and will go off after a few sec-
onds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to “ON”.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
If the “VSC TRAC” warning light and slip
indicator light comes on while driving, the
traction control system does not work.
However, as the brakes operate normally
when applied, it is no problem to continue
your driving. In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
The “AUTO LSD” system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system is used only when wheel
spinning occurs in a ditch or rough
surface.
This system is effective in case one of
the rear wheels is spinning.

NOTICE
Do not use the “AUTO LSD” system
in conditions other than the above. A
much greater steering effort and more
careful cornering control will be re-
quired.
To activate the system, push the “AUTO
LSD” switch with the vehicle stopped.
The “AUTO LSD” is activated under the
following condition. At this time, the
“AUTO LSD” indicator light will come
on.
The driving mode is set in the two −
wheel drive mode (in the four −wheel
drive mode, the system does not
work.)
Driving at a speed under 100 km/h (62
mph)
To cancel the system, push the “AUTO
LSD” switch once again. If the engine is turned off while the
“AUTO LSD” indicator light is on and then
restarted, the indicator light will turn off
automatically.

The vehicle stability control system
helps provide integrated control of the
systems such as anti −lock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control activates
when the vehicle speed is more than 15
km/h (9 mph).
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 sys-
tem is in the self −check mode, but does
not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks and an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” in
Section 7 −2.)Without tachometer
