NOTICE
Do not drive the vehicle with the warning light onÐeven for one block.It may ruin the engine.
(e) Malfunction indicator lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible. (f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(g) ºABSº Warning Light
This light warns that there is a problem
somewhere in your anti- lock brake sys-
tem.
If the light comes on while you are driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti- lock brake system is not assisting
brake performance so that the wheels can
lock- up during sudden braking or braking
on slippery road surfaces.Vehicles with rear differential lock sys-
temÐ
The anti- lock brake system does not oper-
ate when the rear differential is locked. It
is normal operation for the ºABSº warning
light to be on at this time.
(h) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, seat belt pretension-
er assembly, inflators, warning light, inter-
connecting 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 ºACCº or
ºONº position or remains on.
The light comes on or flashes while
driving.

(vehicles with automatic transmis-
sion)
This light warns that the transmission
ºParkº mechanism is not engaged. If the
front drive control lever is in the ºNº posi-
tion while the selector lever is in the ºPº
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 ºNº,
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 ºPº. 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 (Canada)
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,

released.
For starting tips, see Part 3.
ºONºÐEngine on and all accessories on.
This is the normal driving position.
ºACCºÐAccessories such as the radio
operate, but the engine is off.
If you leave the key in the ºACCº or
ºLOCKº position and open the driver's
door, a buzzer will remind you to remove
the key.
ºLOCKºÐEngine 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 ºACCº to the ºLOCKº position. On
vehicles with an automatic transmission,
the selector lever must be in the ºPº posi-
tion before pushing the key.
When starting the engine, the key may
seem stuck at the ºLOCKº 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 ºONº
position if the engine is not running.The battery will discharge and the ignition could be damaged.

Vehicles with cruise controlÐWhen the cruise control is being used, eve n if you downshift the transmission by turning off the overdrive
switch, engine braking will not be applied because the cruise cont rol is not cancelled. For ways to decrease the vehicle speed, see
ºCruise controlº in this chapter.

'99 Tacoma (U)

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of ºPº position when the
brake pedal is depressed (with the ignition
switch in ºONº position and the selector
lever pulled toward you).
(a) Normal driving
1. Start the engine as instructed in ºHow to start the engineº in Part 3. The
transmission must be in ºPº or ºNº.
2. With your foot holding down the brake pedal, shift the selector lever to ºDº.
In ºDº position, the automatic transmission
system will select the most suitable gear
for running conditions such as normal
cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch 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 switch 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.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Turn off the overdrive switch. The ºO/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the º2º position when the
vehicle speed drops down to or lower
than 106 km/h (66 mph). The transmis-
sion will downshift to the second gear
and more powerful engine braking will
be obtained.
Shift into the ºLº position when the
vehicle speed drops down to or lower
than 61 km/h (38 mph). The transmis-
sion will downshift to the first gear and
maximum engine braking will be ap-
plied. Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease
the vehicle speed, see ºCruise controlº in
this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
NOTICE
To prevent engine overrevving, do not
downshift if you are going faster thanthe above speed in each position.
(c) Using º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in º2º or ºLº, you
can start the vehicle in motion as with the
lever in ºDº.

'99 Tacoma (U)
84
With the selector lever in º2º, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ºLº, the trans-
mission is engaged in the first gear.
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to keepengine rpm from going into the red zone. The approximate maximum al-
lowable speed for each position isgiven below for your reference:
º2º 124 km/h (77 mph). . . . . . .
ºLº 72 km/h (45 mph) . . . . . . .
Do not continue hill climbing for a
long time in the º2º or ºLº posi-tion. This may cause severe auto-
matic transmission damage from
overheating. To prevent such dam-age, use ºDº position for hill climb-ing or hard towing.
(d) 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
ºRº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever fully to securely apply the parking brake.
3. With the brake pedal pressed down, shift the selector lever to the ºPº posi-
tion.
CAUTION
While the vehicle is moving, never
attempt to move the selector lever
into ºPº position under any circum-
stances. Serious mechanical damage
and loss of vehicle control may re-
sult.
(f) Good driving practice
If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
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
Do not hold the vehicle on an up-
grade with the accelerator pedal. Itcan cause the transmission to over- heat. Always use the brake pedal or
parking brake.

(g) Rocking your vehicle if stuck
CAUTION
If your vehicle becomes stuck in
snow, mud, sand, etc., then you may
attempt to rock the vehicle free by
moving it forward and backward. Do
not attempt this procedure if people
or objects are anywhere near the ve-
hicle. During the rocking operation
the vehicle may suddenly move for-
ward or backward as it becomes un-
stuck, causing injury or damage to
nearby people or objects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-age to the transmission and otherparts.
Do not depress the accelerator ped-
al while shifting the selector lever or before the transmission is com-
pletely shifted to forward or reversegear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck afterrocking the vehicle several times,
consider other ways such as tow-ing.
(h) If you cannot shift the selector le-
ver out of ºPº position
If you cannot shift the selector lever from
the ºPº position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see ºIf
you cannot shift automatic transmission
selector leverº in Part 4.
