(g) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the parts monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or the light remains on.
The light comes on while you are driv-
ing.A warning light turning on briefly during
operation does not indicate a problem.
With rear differential lock: However, it is
a normal operation for the light to be on
with rear differential locked. At this time,
the antilock brake system does not oper-
ate.
(h) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the system of the air-
bag and front seat belt pretensioners
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on.
The light comes on or flashes while
driving.(i) Unengaged “Park” Warning Light
(vehicles with automatic transmis-
sion)
This light warns that the transmission
“Park” mechanism is not engaged. If the
front drive control lever is in the “N” posi-
tion while the selector lever is in the “P”
position, the transmission will disengage
and the wheels will not lock.
CAUTION
To restore the park function, shift the
front drive control lever out of “N”,
or the vehicle can move.

(j) Automatic Transmission Fluid Tem-perature Warning Light
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance.
(k) Low Windshield Washer Fluid Level Warning Light (on some models)
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” in Section 73.)
(l) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver ’s door with
the ignition key in the “ACC” or “LOCK”
position. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield
washer fluid level warning light)
1. Apply the parking brake.
2. Turn the ignition key to “ON”, but do not start the engine.
All the service reminder indicators
should come on. The “ABS” warning
light goes off after a few seconds. The
SRS warning light goes off after about
6 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

“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.Vehicles with manual transmission—
You must push in the key to turn the key
from “ACC” to the “LOCK” position.
Vehicles with automatic transmission—
You must shift the selector lever into the
“P” position before turning the key from
“ACC” to the “LOCK” position.
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.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.

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” position and the lock re-
lease button depressed).

(b) Overdrive switch
You can select either third gear (with
overdrive off) or fourth gear (with over-
drive 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 be on automatically.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.
(c) 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”.
When the front drive control lever is in
“L4” (lowspeed position, fourwheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
“Fourwheel drive system” 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 turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low or
when the front drive control lever is in
“L4” (lowspeed position, fourwheel
drive), the transmission will not shift into
the overdrive gear even with the overdrive
on. (See “Fourwheel drive system” in this
section for information of the front drive
control lever.)
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.
(d) 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.

’03 Tacoma U (L/O 0209)

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.

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 the second gear.
With the selector lever in “L”, the trans-
mission is engaged in first gear.
