Cold Temperature Operation
For Vehicles With the 2.4L L4 Engine
If in an area of extreme cold, where the temperature
falls below−20°F (−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at extremely low
temperatures. Always use an oil that meets the required
specication, GM6094M. See “What Kind of Engine
Oil to Use” for more information.
Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all that is needed for
good performance and engine protection.
Engine oil system ushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has the Engine Oil Life System, a computer
system that indicates 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 is
indicated can vary considerably. For the oil life system
to work properly, the system must be reset every
time the oil is changed.
When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE OIL SOON message comes on. SeeDIC
Warnings and Messages on page 3-37. Change
the oil as soon as possible within the next 600 miles
(1 000 km). It is possible that, if driving under the best
conditions, the oil life system might not indicate that
an oil change is necessary for over a year. However, the
engine oil and lter must be changed at least once a
year and at this time the system must be reset.
Your dealer/retailer has trained service people who will
perform this work using genuine parts and reset the
system. It is also important to check the oil regularly and
keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 3,000 miles (5 000 km) since the last oil
change. Remember to reset the oil life system whenever
the oil is changed.

How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter remove the lter from the
vehicle and lightly shake the lter to release loose
dust and dirt. If the lter remains caked with dirt, a new
lter is required.
To inspect or replace the lter, open the clamps that
hold the cover on and lift off the cover. Be sure to
reinstall the cover tightly.
{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
ames if the engine backres. If it is not there and
the engine backres, 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 backre can
cause a damaging engine re. And, dirt can
easily get into the engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.
Automatic Transmission Fluid
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid
loss. If a leak occurs, take your vehicle to a
dealer/retailer and have it repaired as soon as possible.
Change the uid and lter at the intervals listed in
the Maintenance Schedule. SeeScheduled Maintenance
on page 6-4. Be sure to use the transmission uid
listed inRecommended Fluids and Lubricants on
page 6-12.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission uid listed
inRecommended Fluids and Lubricants on
page 6-12.
5-22

Manual Transmission Fluid
It is not necessary to check the manual transmission
uid level. A transmission uid leak is the only reason for
uid loss. If a leak occurs, take the vehicle to a
dealer/retailer for service. Have it repaired as soon as
possible. You may also have the uid level checked
by your dealer/retailer when the oil is changed.
SeeRecommended Fluids and Lubricants on page 6-12
for the proper uid to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master cylinder
reservoir.
SeeBrakes on page 5-32for more information.
Cooling System
The Cooling System allows the engine to maintain the
correct working temperature.

Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a
problem with engine overheating, seeEngine
Overheating on page 5-29.
What to Use
{CAUTION:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch re and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
Gives freezing protection down to−34°F (−37°C),
outside temperature.
Gives boiling protection up to 265°F (129°C),
engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used, the
engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core,
and other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 6-12for more information.
5-25

Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The coolant surge tank is located in the engine
compartment on the driver’s side of the vehicle. See
Engine Compartment Overview on page 5-12for more
information on location.
Check to see if coolant is visible in the coolant surge
tank. If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down. If
coolant is visible but the coolant level is not at or above
the FULL COLD mark, add a 50/50 mixture of clean,drinkable water and DEX-COOL
®coolant at the coolant
surge tank, but be sure the cooling system is cool
before this is done. See Engine Coolant Engine Coolant
for more information.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
FILL line.
Do not overll the surge tank. Too much coolant can
result in an overow condition when the uid is hot.
How to Add Coolant to the Surge Tank
{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.
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure could
cause the engine to overheat and be severely
damaged.
5-26

3. Fill the coolant surge tank with the proper mixture,
to the COLD FILL line. Wait about ve minutes,
then check to see if the level is below the COLD
FILL line. If the level is below the line, add additional
coolant to bring the level up to the line. Repeat
this procedure until the level remains constant at the
COLD FILL line for at least ve minutes.4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the COLD FILL line, add more of the proper mixture
to the coolant surge tank until the level reaches
the COLD FILL line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
See your dealer/retailer, if necessary.
5-28

Engine Overheating
The vehicle has an indicator to warn of engine
overheating.
There is an engine coolant temperature warning light on
your vehicle’s instrument panel. SeeEngine Coolant
Temperature Warning Light on page 3-28for more
information.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
SeeRoadside Assistance Program on page 7-6.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fan is running. If
the engine is overheating, the fan should be running.
If not, do not continue to run the engine and have
the vehicle serviced.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.
Notice:If the engine catches re because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.
If Steam Is Coming From The Engine
Compartment
{CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away from
the vehicle until it cools down. Wait until there is
no sign of steam or coolant before you open
the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.

regularly, unless there is a suspected leak or an unusual
noise. If there is uid loss, have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering uid:
1. Turn the engine off and let it cool down.
2. Clean the top and cap of the reservoir.
3. Remove the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten.
5. Remove the cap again and check the uid level on
the dipstick.
The level should be between the COLD and HOT
marks. If necessary, add only enough uid to bring the
level up to the COLD mark.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 6-12.
Always use the proper uid.
Notice:Use of the incorrect uid may damage the
vehicle and the damages may not be covered by
