A computer system controls the engine's idle
speed. When you start your vehicle, the engine's
idle speed normally runs high. These faster
engine speeds will make your vehicle move
slightly faster than its normal idle speed. It
should, however, slow down after a short time.
If it does not, have the idle speed checked.
*
[ST07390(ALL)07/95]
If the engine idle speed does not slow down
automatically, do not allow your vehicle to idle
for more than 10 minutes. Have the vehicle
checked.
*
[ST07400(ALL)05/95]
RWARNING
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the
risk of fire or other damage.

Check Engine Warning Light
*
[LG04550(ALL)05/95]
The Powertrain On-Board Diagnostic II (OBD II)
system consists of the hardware and software
necessary to monitor the operation of the
powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain
control system during normal operation. If an
emission problem is detected, the Check Engine
Warning Light (in the cluster) is turned on.
*
[LG04575(ALL)05/95]
Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
installed. Do not install these devices by tapping
into or running wires close to powertrain control
system wires or components.
[LG04600(ALL)07/95]
The light comes on briefly when you turn the
ignition key to the ON position, but it should
turn off when the engine starts. If the light does
not come on when you turn the ignition to ON
or if it comes on and stays on when you are
driving, have your vehicle serviced as soon as
possible. This indicates a possible problem with
one of the vehicle's emission control systems.
You do not need to have your vehicle towed in.
[LG04650(ALL)08/95]
If the light turns on and off at one (1) second
intervals while you are driving the vehicle, it
means that the engine is misfiring. If this
condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle
serviced at the first opportunity. You do not
need to have your vehicle towed in.
[LG04700(ALL)08/95]
If the light turns on and off on rare occasions
while you are driving, it means that a
malfunction occurred and the condition corrected
itself.

79 [LG04750(ALL)08/95]
An example of a condition which corrects itself
occurs when an engine running out of fuel
begins to misfire. In this case, the Check Engine
Warning Light may turn on and will then set a
Diagnostic Trouble Code indicating that the
engine was misfiring while the last of the fuel
was being consumed. After refueling, the Check
Engine Warning Light will turn off after the
vehicle has completed three consecutive warm
up cycles without a mifire condition occurring.
A warm up cycle consists of engine start from a
cold condition (engine at ambient temperature)
and running until the engine reaches normal
operating temperature.
[LG04825(ALL)07/95]
On the fourth engine start up, the Check Engine
Warning Light will turn off as soon as the
engine begins to crank. It is not necessary to
have the engine serviced.
[LG04875(ALL)07/95]
Under certain conditions, the Check Engine
Warning Light may come on if the fuel cap is
not properly installed. If the Check Engine
Warning Light comes on and you suspect the
fuel cap is not properly installed, pull off the
road as soon as it is safely possible and turn off
the engine. Remove and replace the fuel cap,
making sure it is properly seated.
[LG04900(ALL)07/95]
After completing three consecutive warm-up
cycles and on the fourth engine start-up, the
Check Engine Warning Light should turn off. If
the light does not go off after the fourth engine
restart, have your vehicle serviced by your
dealer or a qualified technician.

The 4WD light will go off after a few seconds
and stay off if all systems are operating
correctly. If a problem is detected, the 4WD
warning light will flash a certain number of
times indicating the location of the problem. The
flashing will continue until the problem is
corrected. Each time the ignition key is turned
on the controller will detect the problem and
flash the signal. The 4WD system remains safe to
operate and the vehicle should be returned for
service.

*
[SV00600(ALL)01/95]
2. We want to make servicing your vehicle as
easy as possible. To help you:
*
[SV00700(ALL)01/95]
q
We highlight do-it-yourself items in yellow in
the engine compartment so that you can find
them easily.
*
[SV00800(ALL)01/95]
q
When possible, we design parts Ð such as
the headlamp bulbs Ð that can be replaced
without tools.
*
[SV00900(ALL)05/94]
q
We give you a Maintenance Schedule that
makes tracking routine service for your
vehicle easy. The maintenance schedule is
located in theMaintenance Schedule and Record
booklet.
*

Checking and Adding Engine Oil
*
[SV13800(ALL)03/95]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.
%*
[SV13900(ALL)03/95]
Checking the engine oil level:
*
[SV14000(ALL)02/95]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[SV14050(ALL)03/95]
2. Set the parking brake, making sure the
gearshift is securely latched in P (Park).
*
[SV14100(ALL)02/95]
3. Open the hood. Protect yourself from engine
heat.
*
[SV14200(ALL)03/95]
4. Locate the engine oil dipstick (highlighted in
yellow) and carefully pull it out of the
engine.
*
[SV14300(ALL)01/95]
5. Wipe the dipstick clean and put it back into
position, making sure it is fully seated.

6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QTº line, add
engine oil as necessary. If the oil level is
beyond the letter ªFº in Full, engine damage
or high oil consumption may occur and
some oil must be removed from the engine.

[SV14600(ALL)01/95]
7. Put the dipstick back in and make sure it is
fully seated.

[SV14700(ALL)03/95]
Adding engine oil
*
[SV14800(ALL)01/95]
It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED
engine oil of the preferred viscosity. Your
vehicle's warranty coverage may not apply if
engine damage is caused by the use of improper
engine oil.
*
[SV15000(ALL)03/95]
Add engine oil through the oil filler cap
highlighted in yellow. To add oil, remove the
filler cap and use a funnel to pour oil into the
opening. Be careful not to overfill the engine.
Recheck the oil level after you finish adding oil.

[SV17500(ALL)02/95]
NOTE: Be sure to read and understand
Precautions When Servicing Your
Vehicleat the beginning of this chapter.
*
[SV17700(ALL)08/95]
Your vehicle's engine coolant protects the engine
from overheating in the summer and from
freezing in the winter. Check the level of the
engine coolant at least once a month, but
preferably each time you stop for fuel. Simply
look at the engine coolant recovery reservoir
located in the engine compartment. To locate
this reservoir, see the diagram of your vehicle's
engine underEngine Compartmentin this chapter.

[SV26460(ALL)03/95]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.

[SV26470(ALL)05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

[SV26500(ALL)02/95]
Tire Rotation
*
[SV26600(ALL)03/95]
Because your vehicle's front and rear tires
perform different jobs, they often wear
differently. To make sure your tires wear evenly
and last longer, rotate them at the mileage
shown in theMaintenance Schedule and Record
booklet which came with your vehicle.
*
[SV26700(ALL)07/92]
Rotate the tires according to the following
diagram. If you notice that the tires wear
unevenly, have them checked. If your light truck
has a temporary spare tire, do not include it in
the tire rotation pattern.
*
[SV26750(ALL)03/90]
In situations where the tires differ from front to
rear (snow/traction), simply rotate using a side
to side pattern.
