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 system.
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
airbag system is operating properly.
The warning light system monitors the air-
bag sensor assembly, inflator, warning
light, interconnecting 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 while driving.

(i) Unengaged ºParkº Warning Light (ve-
hicles with automatic transmission)
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,
see ºAdding washer fluidº in Chapter 7- 3.)
(l) Light Reminder Buzzer This buzzer will sound if the driver 's door
is opened while the ignition switch is
turned to the ºLOCKº position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-
light switch is on.
(m) Key Reminder Buzzer This buzzer reminds you to remove the
key when you open the driver 's door with
the ignition key in the ºACCº or ºLOCKº
position. CHECKING SERVICE REMINDER INDICA-
TORS (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 ºACCº. The SRS airbag warning light should
come on. It goes off after about 6 se-
conds.
3. Turn the ignition key to ºONº, but do not start the engine.
All the service reminder indicators ex-
cept the SRS airbag warning light
should come on. The ºABSº warning
light goes off after a few seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, either the bulb is burned out or the
circuit is in need of repair. Have it
checked by your Toyota dealer as soon as
possible.

ºSTARTºÐStarter motor on. The key

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.

Position for engine braking
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.

'98 Tacoma (U)77
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 control±When 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.
(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.
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.
