Starting and Operating
Your Vehicle
Starting the Diesel Engine
Your diesel engine starts differently than a gasoline
engine.
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position — that’s a
safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
(Pickup Models Only)
Move your shift lever to neutral and hold the clutch pedal
to the floor while starting the engine. Your vehicle won’t
start if the clutch pedal is not all the way down — that’s
a safety feature.
Starting Your Engine
1. Turn your ignition key to RUN.
Observe the wait to start light. SeeWait to Start
Light on page 3-7. This light may not come on if
the engine is hot.
2. As soon as the wait to start light goes off,
immediately turn the ignition key to START.
When the engine starts, let go of the key.
Your engine has a fast warm-up glow plug system.
The wait to start light will illuminate for a much
shorter time than most diesel engines, due to the
rapid heating of the glow plug system.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor.
Notice:If the wait to start light stays on after
starting your vehicle, your vehicle may not run
properly. Have your vehicle serviced right away.
3. If the engine does not start after 15 seconds of
cranking, turn the ignition key to LOCK. Wait
one minute for the starter to cool, then try the
same steps again.
If you’re trying to start your engine after you’ve run
out of fuel, follow the steps inRunning Out of Fuel
on page 5-11.

The high idle speed will be temporarily interrupted
and the engine speed will return to normal if any of
the following conditions occur:
•The brake pedal is applied.
•The accelerator pedal is pressed.
•The automatic transmission is shifted out of
PARK (P) or NEUTRAL (N).
•The clutch pedal on the manual transmission is
pressed (pickup models).
•Vehicle speed is detected.
Once these inputs are removed, the engine idle speed
will slowly ramp back up to high idle after the normal
delay, if the conditions for engine coolant temperature
and air intake temperature are still met.
Manual High Idle System
(Van Models Only)
If your vehicle has this
feature, the manual high
idle switch is located
on the instrument panel.
This system can be used to increase your engine idle
speed whenever the following conditions are met:
•The brake pedal is not pressed.
•The vehicle speed is below about 5 mph (8 km/h).
•The transmission is in NEUTRAL (N) or PARK (P).
The manual high idle feature is activated by pressing
the switch on the instrument panel. When the switch is
pressed again, or any of the previous conditions are not
met, manual high idle will be deactivated. The manual
high idle has been preset at the factory. Your dealer may
change the setting to fit your needs.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a computer which monitors operation
of the fuel, timing, and emission control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner environment.The check engine light comes on to indicate when service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may prevent
more serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls may not
work as well, your fuel economy may not be as good,
and your engine may not run as smoothly. This could
lead to costly repairs that may not be covered by
your warranty.
Notice:Modi cations made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modi cations to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. Pickup Models

Towing
Towing a Trailer
When towing at high altitude on steep uphill grades,
consider the following:
Engine coolant will boil at a lower temperature than sea
level. If you turn your engine off immediately after towing
at high altitude on steep uphill grades, your vehicle may
show signs similar to engine overheating.To avoid this, let the engine run while parked (preferably
on level ground) with automatic transmission equipped
vehicles in PARK (P) or manual transmission equipped
vehicles in NEUTRAL with the park brake applied for at
least five minutes before turning the engine off. If you do
get the overheat warning, seeEngine Overheating on
page 5-39.

Diesel Fuel Requirements and
Fuel System
Some states and provinces have restrictions on the
purchase of diesel fuel for light-duty vehicles and require
you to buy permits or pay special taxes. Some of these
restrictions apply only to residents, and others apply
to both residents and visitors. These restrictions can
change. To learn the current restrictions in any state
or province, contact your auto club, the police or other
officials.
Diesel Engine Fuel
Notice:Diesel fuel or fuel additives not
recommended in this manual could damage your
fuel system, fuel-operated heater (FOH) (Van models
only) and engine. Your warranty would not cover
this damage. And:
Diesel fuel that has been mixed with engine oil
or automatic transmission uid could damage
your engine and emission controls.
Aftermarket diesel fuel additives are not tested
by General Motors. Some additives, particularly
those which contain alcohol or water emulsi ers,
may damage your fuel system. If you believe that
unique circumstances call for a fuel additive to
be used, consult your dealer for advice.
If you ever run out of diesel fuel, it can be difficult
to restart your engine. To avoid all this, never let
your tank get empty.
If gasoline is ever accidentally added to the fuel
tank, to avoid severe engine damage, do not run
the engine until the fuel tank can be drained.
If you run out of fuel,Running Out of Fuel on page 5-11
tells you how to restart your engine.

Checking Engine Oil
It is a good idea to check your engine oil level every
time you get fuel.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-18
for the location of the engine oil dipstick.In order to get an accurate reading, the oil must be
warm, at normal operating temperature, and the vehicle
must be on level ground.
1. Turn off the engine and give the oil at least
five minutes to drain back into the oil pan. With a
cool engine, allow 30 minutes. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or a cloth, then push it back in all the way. Remove
it again, keeping the tip down.
When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of the
dipstick, you will need to add at least two quarts/liters of
oil. But you must use the right kind. This section explains
what kind of oil to use. For engine oil crankcase capacity,
seeSpeci cation Charts on page 5-50.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, the engine could be damaged.

Automatic Transmission Fluid
When to Check and Change
(Pickup Models)
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every 25,000 miles
(41 500 km) if the vehicle is mainly driven under one
or more of these conditions:
•In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•In hilly or mountainous terrain.
•When doing frequent trailer towing.
•Uses such as found in taxi, police or
delivery service.
If you do not use your vehicle under any of
these conditions, change the fluid and filter
every 50,000 miles (83 000 km).
SeeScheduled Maintenance on page 6-4.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at the dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice:Too much or too little uid can damage your
transmission. Too much can mean that some of the
uid could come out and fall on hot engine part or
exhaust system parts, starting a re. Too little uid
could cause the transmission to overheat. Be sure
to get an accurate reading if you check your
transmission uid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
•When outside temperatures are above 90°F (32°C).
•At high speed for quite a while.
•In heavy traffic — especially in hot weather.
•While pulling a trailer.
