When the engine is running and this message appears,
the engine oil level may be too low. There may also
be another problem causing low oil pressure.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches ®re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
Change Engine Oil Message
If this message comes on and stays on after you started
the engine, have the oil changed.

·Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
·Lamps:Are they all working? Are the lenses clean?
·Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all in¯ated
to the recommended pressure?
·Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
·Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as ªhighway
hypnosisº? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of awareness,
or whatever.There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on
the road, the drone of the engine, and the rush of
the wind against the vehicle that can make you sleepy.
Do not let it happen to you! If it does, your vehicle
can leave the road in
less than a second,and you
could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
·Make sure your vehicle is well ventilated,
with a comfortably cool interior.
·Keep your eyes moving. Scan the road ahead
and to the sides. Check your mirrors and your
instruments frequently.
·If you get sleepy, pull off the road into a rest,
service or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

Engine Oil
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
5-13
Page 316 of 462
When to Add Engine Oil
If the oil is at or below the cross-hatched area at the
tip of the dipstick, then you will need to add at least
one quart of oil. But you must use the right kind.
This section explains what kind of oil to use.
For engine oil crankcase capacity, see
Capacities
and Speci®cations on page 5-108.
Notice:Do not add too much oil. If your engine
has so much oil that the oil level gets above
the cross-hatched area that shows the proper
operating range, your engine could be damaged.See
Engine Compartment
Overview on page 5-12
for the location of the
engine oil ®ll cap.
Be sure to add enough oil to put the level somewhere
in the proper operating range in the cross-hatched area.
Push the dipstick all the way back in when you are
through.
What Kind of Engine Oil to Use
Look for two things:
·GM6094M
Your vehicle's engine requires oil meeting GM
Standard GM6094M. You should look for and use
only an oil that meets GM Standard GM6094M.
5-14
Page 318 of 462
Notice:Use only engine oil identi®ed as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certi®ed For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench
žoil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below-20ÉF (-29ÉC), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will provide
easier cold starting and better protection for your
engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol meet GM Standard GM6094M
are all you will need for good performance and engine
protection.
When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and ®lter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE ENGINE OIL message will come on. Change
your oil as soon as possible within the next two times you
stop for fuel. It is possible that, if you are driving under the
best conditions, the oil life system may not indicate that
an oil change is necessary for over a year. However, your
engine oil and ®lter must be changed at least once a year
and at this time the system must be reset. Your dealer
has GM-trained people who will perform this work using
genuine GM parts and reset the system. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.

6. Latch the hooks to secure the panel in place. If the
panel moves easily, check that the tabs are seated
correctly in the slots.
7. Put the duct back on and reinstall the clamps.
{CAUTION:
Operating the engine with the air cleaner/®lter
off can cause you or others to be burned.
The air cleaner not only cleans the air,
it helps to stop ¯ame if the engine back®res.
If it is not there and the engine back®res,
you could be burned. Do not drive with it off,
and be careful working on the engine with
the air cleaner/®lter off.
Notice:If the air cleaner/®lter is off, a back®re can
cause a damaging engine ®re. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/®lter in place when you are driving.
Automatic Transaxle Fluid
When to Check and Change Automatic
Transaxle Fluid
A good time to check your automatic transaxle ¯uid
level is when the engine oil is changed.
Change both the ¯uid and ®lter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:
·In heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) 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 ¯uid and ®lter at
100,000 miles (166 000 km).
See
Scheduled Maintenance on page 6-4for more
information.
5-19
Page 324 of 462
How to Add Fluid Automatic Transaxle
Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle ¯uid to use. SeeRecommended Fluids
and Lubricants on page 6-12.
If the ¯uid level is low, add only enough of the proper
¯uid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough ¯uid at the
dipstick hole to bring it to the proper level.
It does not take much ¯uid, generally less than
one pint (0.5 L). Do not over®ll.
Notice:Use of automatic transaxle ¯uid labeled
other than DEXRONž-III may damage your vehicle,
and the damages may not be covered by your
warranty. Always use DEXRON
ž-III labeled automatic
transaxle ¯uid.
3. After adding ¯uid, recheck the ¯uid level as
described under ªHow to Check Automatic
Transaxle Fluidº.
4. When the correct ¯uid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs ®rst, if you add
only DEX-COOL
žextended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating
on page 5-25.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC)
·Give boiling protection up to 265ÉF (129ÉC)
·Protect against rust and corrosion
·Help keep the proper engine temperature
·Let the warning messages and gages work
as they should
Notice:Using coolant other than DEX-COOLžmay
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs ®rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
ž(silicate-free) coolant in your vehicle.
5-22
Page 327 of 462
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see
Cooling System on page 5-28.
Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the over¯ow tube on the radiator ®ller neck.
The radiator pressure cap is located at the front of the
engine compartment on the passenger's side of the
vehicle. See
Engine Compartment Overview on
page 5-12for more information on location.
Engine Overheating
You will ®nd an engine coolant temperature gage on
your vehicle's instrument panel cluster. SeeEngine
Coolant Temperature Gage on page 3-48. You
also have an engine coolant temperature warning
message on your instrument panel. See
Engine Coolant
Temperature Warning Message on page 3-54.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates ®ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signi®cant loss in power and engine
performance. The temperature gage will indicate
an overheat condition exists. Driving extended
miles (km) and/or towing a trailer in the overheat
protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the oil
life system. See
Engine Oil on page 5-13.

Cooling System
When you decide it is safe to lift the hood, here is what
you will see:
A. Radiator Pressure Cap
B. Electric Engine Cooling Fans
C. Coolant Recovery Tank{CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
If the coolant inside the coolant recovery tank is boiling,
do not do anything else until it cools down. The
vehicle should be parked on a level surface.
The coolant level should be at or above the FULL COLD
mark. If it is not, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
5-28
Page 332 of 462
How to Add Coolant to the Coolant
Recovery Tank
If you have not found a problem yet, but the coolant
level is not at or above the FULL COLD mark, add
a 50/50 mixture of
clean, drinkable waterand
DEX-COOLžengine coolant at the coolant recovery
tank. SeeEngine Coolant on page 5-22for more
information.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
žcoolant.
Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
