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 spin or
skid.
(e) Using “2” and “L” positions
The “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “2” or “L”, you
can start the vehicle in motion as with the
lever in “D”.
With the selector lever in “2”, the vehicle
will start in first gear and automatically
shift to second gear.
With the selector lever in “L”, the trans-
mission is engaged in first gear.

2004 TUNDRA from Sep. ’03 Prod. (OM34426U)
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.
(h) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, the
overdrive should be turned off. Be sure
to turn the switch on immediately after-
ward.
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.
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. And
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)
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:
Tw o
−wheel drive models
gear km/h (mph)
1 45 (28)
2 85 (53)
3 125 (78)
4 165 (112)
Four −wheel drive models
gear km/h (mph)
“H2” or “H4” “L4”
1 45 (28) 15 (9)
2 85 (53) 30 (18)
3 125 (78) 45 (28)
4 165 (103) 70 (43)
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 fifth gear.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
NOTICE
Make sure the vehicle is completely
stopped before shifting into reverse.

Use the front drive control lever to se-
lect the following transfer modes.
“H2” (high speed position, twowheel
drive): Lever at “H2”
Use this for normal driving on dry, hard −
surfaced roads. This position gives greater
economy, the quietest ride and least wear.
“H4” (high speed position, fourwheel
drive): Lever at “H4”
Use this for normal driving on wet, icy or
snow −covered roads. This position pro-
vides greater traction than two− wheel
drive. “N” (neutral position): Lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped.
“L4” (low speed position, fourwheel
drive):
Lever at “L4”
Use this for maximum power and traction.
Use “L4” for climbing or descending steep
hills, off −road driving, and hard pulling in
sand, mud or deep snow.
The “4WD” (four −wheel drive) indicator
light comes on when the “H4”, “N” or “L4”
mode is selected.
See “(c) Shifting procedure (lever type)”
for further instructions.
Advice for driving on slippery roads in
“L4” (low speed position, four wheel
drive) mode
If you shift the front drive control lever to
“L4” and the automatic transmission lever
to “2” when you drive in steep off −road
areas, the output of the brake can be
controlled effectively by the traction con-
trol system, which assists the driver to
control the driving power of 4 wheels. Use the “L” position of the automatic
transmission lever for maximum power
and traction when your wheels get stuck
or when you drive down a steep incline.
In the following cases, the output of the
brake can be controlled by the traction
control system if the engine speed is un-
der 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).

Use the “L” position of the automatic
transmission lever for maximum power
and traction when your wheels get stuck
or when you drive down a steep incline.
In the following cases, the output of the
brake can be controlled by the traction
control system if the engine speed is un-
der 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).

and the automatic transmission lever in
the “L” position or the automatic trans-
mission lever in the “D” or “2” with the
transmission downshifting to the first
gear
The transfer mode in the “4LO” mode
and the automatic transmission lever in
the “R” position
(As for the automatic transmission lever
positions, see “Automatic transmission” in
this Section.) 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 “H2” AND “H4”
To shift from “H2” to “H4”,
reduce the
vehicle speed to less than 80 km/h (50
mph) and move the front drive control
lever. If the indicator light does not come
on when you shift the transfer into “H4”,
drive straight ahead while accelerating or
decelerating, or drive forward or backward
in a short distance. You need not depress
the clutch pedal.
If you have trouble shifting in cold weath-
er, reduce the vehicle speed or stop the
vehicle and reshift.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop the
slipping or spinning before shifting.
To shift from “H4” to “H2”, simply move
the front drive control lever.
This can be done at any speed. You need
not depress the clutch pedal.
If the indicator light does not go off when
you shift the transfer into “H2”, drive
straight ahead while accelerating or decel-
erating, or drive forward or backward in a
short distance.

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.
Ty p e A
Ty p e B
“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 warning
light will come on and will go off after a
few seconds.
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.
The brake actuator temperature increases
during continuous operation of the above
mentioned systems such as on slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
traction control system can no longer op-
erate. In this case, immediately stop your
vehicle at a safe place.

’04 TUNDRA_U (L/O 0309)

2004 TUNDRA from Sep. ’03 Prod. (OM34426U)
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 “VSC TRAC” warning light
will come on and the traction control sys-
tem 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 “VSC TRAC” warning
light goes off.
If the 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 on a slip-
pery 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.

NOTICE
Do not drive with the “AUTO LSD”
switch continuously turned on.
The vehicle stability control system
helps provide integrated control of the
systems such as antilock 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 72.)

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
Pedal type—
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal once again.
Lever type—
To set: Pull out on the lever. For better
holding power, first depress the brake
pedal and hold it while setting the parking
brake.
To release: Press the lock release button
(1), turn the lever (2), then push it in (3).
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.
TURNING THE SYSTEM ON
To operate the cruise control, press the
“ON−OFF” button. This turns the system
on. The indicator light in the instrument
panel shows that you can now set the
vehicle at a desired cruising speed. Anoth-
er press will turn the system completely
off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the “ONOFF” button
off when not using the cruise control.
