CAUTION!
Do not fill a fuel container on a plas-
tic truck bed liner, a rubber truck
bed mat, or any other insulating
material. A static electricity charge
could cause a spark and fire haz-
ard. The proper procedure is to
place an approved fuel container
on the ground away from the truck for filling.
2. To remove the fuel tank cap, turn
the cap slowly counterclockwise,
then pause slightly before remov-
ing it. after removing the cap, hang
it on the cap hanger.
It is not unusual to hear a slight swoosh
when the cap is opened. When installing,
turn the cap clockwise till you hear a click.

If the cap is not tightened securely, the malfunction indicator lamp comes on.
Make sure the cap is tightened securely. The indicator lamp goes off after driving several times. If the indicator lamp does
not go off, contact your Toyota dealer as soon as possible.
CAUTION!
Make sure the cap is tightened se-
curely to prevent fuel spillage in
case of an accident.
Use only a genuine Toyota fuel
tank cap for replacement. It has a
built in check valve to reduce fuel tank vacuum.

60(a) Brake System Warning Light This light has the following functions: Parking brake reminder
If this light is on, make sure the parking
brake is
fully released. The light should go
off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off the
road. Then stop the vehicle carefully.There may be a problem somewhere in
the brake system. Check the fluid level of
the see-through reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is fully
released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping. If you judge that the brakes still work
adequately, drive cautiously to yournearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
It is dangerous to continue driving
normally when the brake fluid level
is low. CAUTION
!
If the brake fluid level is correct...
Have the warning system checked by
your Toyota dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ONº or
STARTº, the reminder light and buzzer
come on if the driver's seat belt is not fas- tened. Unless the driver fastens the belt,
the light stays on and the buzzer stops af-
ter about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging system. The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, ra
dio, ect., and drive directly to the
nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(d) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop forassistance.
The light may occasionally flicker when
the engine is idling or it may come on brief-
ly after a hard stop. There is no cause for concern if it then goes out when the en-
gine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to indi- cate low oil level, and the oil level must be checked using the level dipstick.

61
NOTICE
Do not drive the vehicle with the warning light onÐeven for one
block. It may ruin the engine.
(e) 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.
(f) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See Fuel gaugeº in Chapter 1-5 for in-structions.)
b. The fuel tank cap is not tightened se-
curely. (See Fuel tank capº in Chapter
1-2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electri- cal system.
If it comes on while you are driving in case
b, have your vehicle checked/repaired by
your Toyota dealer as soon as possible. (g) ABSº 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 driving,
have your vehicle checked by your T
oyota
dealer as soon as possible.
The light will come on when the ignition key is turned to the ONº position. After
about 3 seconds, the light will go off. When the ABSº warning light is on (and
the brake system warning light is off), thebrake system operates conventionally but
anti-lock brake system is not assistingbrake performance so that the wheels can
lock-up during sudden braking or braking
on slippery road surfaces.
(h) SRS Airbag Warning Light
This light will come on when the ignition
key is turned to the ACCº or ONº posi- tion. After about 6 seconds, the light will
go off. This means the airbag system is
operating properly.
The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflator, warning light, intercon-
necting 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 igni-
tion key is turned to the ACCº or ONº
position or remains on. The light comes on while driving.
(i) Light Reminder Buzzer
This buzzer will sound if the driver's door is opened while the ignition switch isturned to the LOCKº position with the
headlight
switch on. Removing the key will
not stop the buzzer as long as the head- light switch is on.
(j) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver's door with the ignition key in the ACCº or LOCKº position.

62(k) Unengaged Parkº Warning Light
(vehicles with automatic tranmis- sion)
This light warns that the transmission
Parkº mechanism is not engaged. If the
front drive control lever is in the Nº posi-
tion while the selector lever is in the Pº

The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making itappear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in proper vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level bechecked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec- trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other w ill still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION!
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops - but no more!

CAUTION!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard-much harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti-lock brake system is designed to automatically prevent lock-up of the
wheels during sudden braking or braking on slippery road surfaces. This assists in
providing directional stability and steeringperformance of the vehicle under these circumstances.
The anti-lock brake system becomes op- erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). You may hear a sound in the engine
compartment for a
few seconds when the
engine is started or just after the vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ABSº brake
pedal: When the anti-lock brake system
function is in action, you may feel the brake pedal pulsating and hear a noise.
In this situation, to let the anti-lock brake
system work for you, just hold the brake
pedal down more firmly. Do not pumpthe brake. This will result in reduced
braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle: Braking c apability is dependent on tire
friction with the road surface.
Even though the anti-lock brake sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and loss of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases: Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differencesin surface height.
CAUTION!
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of different
sizes. You may prevent the antilock brake system from operating at full effectiveness.

1. Check
the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust inside and outside rear view mirrors.
4. Lock both doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Manual transmission: Press the
clutch pedal to the floor and shift the
transmission into neutral. Hold theclutch pedal to the floor until the engine
is started. A starter safety device willprevent the starter from operating if
the clutch pedal is not fully depressed.
Automatic transmission: Put the se-
lector lever in Pº. If you need to restart
the engine while the vehicle is moving, put the selector lever in Nº. A starter
safety device will prevent the starter
from operating if the selector lever is in
any drive position.
4. Automatic transmission only: De-
press the brake pedal and hold it to the
floor until driving off.

122Before starting the engine, be sure to fol-
low the instructions in (a) Before crank- ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system in
your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot engine as follows:
1. With your foot off the accelerator ped-
al, crank the engine by turning the key
to STARTº. Release it when the en-
gine starts.
2. After the engine runs for about 10 sec-
onds, you are ready to drive.
If the weather is below freezing, let the en-
gine warm up for a few minutes before driving.
If the engine stalls...
Simply restart it, using the correct proce- dure given in normal starting. If the engine will not startÐ
See If your vehicle will not startº in Part 4.
Do not crank for more than 30
sec-
onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to
start or stalls frequently, have theengine checked immediately.
NOTICE Always slow down in gusty cross- winds. This will allow you much bettercontrol.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid drivingonto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.
When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission in Pº (automatic) or in first or reverse
(manual). If necessary, block thewheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a T oyota dealer for
assistance.
