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 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.
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
“2” or “L” position. This may cause
severe automatic transmission dam-
age from overheating. To prevent
such damage, “D” position should
be used in hill climbing or hard
towing.(f) 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.
(g) 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.
(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)

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.

Pedal type
Lever type
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.
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in “D” before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the “ − SET” direc-
tion and release it. This sets the vehicle
at that speed. If the speed is not satisfac-
tory, tap the lever up for a faster speed,
or tap it down for a slower speed. Each
tap changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot off
the accelerator pedal. If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CAUTION
For manual transmission:
While driving with the cruise control
on, do not shift to neutral without
depressing the clutch pedal, as this
may cause engine racing or overrev-
ving.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the lever in the “CANCEL”
direction and releasing it
b. Depressing the brake pedal
c. Depressing the clutch pedal (manual
transmission)
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.

’03 TUNDRA_U (L/O 0307)

2003 TUNDRA from Jul. ’03 Prod. (OM 34430U)
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “− SET” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “− SET” direction. On vehicles with automatic transmission,
even if you turn off the overdrive switch
with the cruise control on, engine braking
will not be applied because the cruise
control is not cancelled. To decrease the
vehicle speed, reset to a slower speed
with the cruise control lever or depress
the brake pedal. If you use the brake
pedal, cruise control is cancelled.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the “+ RES” direction will re-
store the speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the “ON
−OFF” button
to turn the system off and then press it
again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

To crank the engine without depressing
the clutch pedal, push the switch with
the ignition on.
The switch stays on as long as the igni-
tion is on. And it will automatically turn off
when the ignition is off. An indicator light
will illuminate to indicate the system is
operating.
This switch cancels the clutch start sys-
tem, which is designed to keep the starter
motor from operating if the clutch pedal is
not depressed all the way down.
The switch allows the vehicle to be driven
out of difficult situations by cranking the
engine with the clutch engaged. Never use the switch for normal engine
starting. Be sure to follow the starting
procedure instructed in “How to start the
engine” in Section 3.

the air inside vehicle.
To turn the air source to RECIRCULATED
mode, press the button. The indicator will
come on. To turn the air source to FRESH
mode, press the button again. The indica-
tor will go off.
To prevent fogging up of the windshield,
the air intake mode may change automati-
cally to FRESH depending on the condi-
tion of the air conditioning system.
“A/C” button
To turn on the air conditioning, press the
“A/C” button. The “A/C” button indicator
will come on. To turn the air conditioning
off, press the button again.
