Engine Cooling System
Messages
A/C Off Due to High
Engine Temp
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
To avoid added strain on a hot
engine, the air conditioning
compressor automatically turns off.
When the coolant temperature
returns to normal, the air
conditioning compressor turns
back on. You can continue to
drive the vehicle.
If this message continues to appear,
have the system repaired by your
dealer/retailer as soon as possible
to avoid damage to the engine.
Coolant Level Low Add
Coolant
This message will display if the
coolant is low, seeEngine Coolant
on page 9‑16.
Engine Overheated —Idle
Engine
This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down.
Engine Overheated —Stop
Engine
This message displays and a
continuous chime sounds if the
engine cooling system reaches
unsafe temperatures for operation.
Stop and turn off the vehicle as
soon as it is safe to do so to avoid
severe damage. This message
clears when the engine has cooled
to a safe operating temperature.
High Coolant Temperature
This message displays if the coolant
temperature is hot, see Engine
Overheating on page 9‑20.
Engine Oil Messages
Change Engine Oil Soon
This message displays when the
engine oil needs to be changed.
When you change the engine oil, be
sure to reset the Oil Life System.
See Engine Oil Life System
on
page 9‑12and Driver Information
Center (DIC)on page 4‑25for
information on how to reset the
system. See Engine Oil
on
page 9‑10and Scheduled
Maintenanceon page 10‑2for
more information.
Engine Oil Hot, Idle Engine
This message displays when the
engine oil temperature is too hot.
Stop and allow the vehicle to idle
until it cools down.
Driving and Operating 8-61
Driving On Grades
Reduce speed and shift to a lower
gear before starting down a long
or steep downgrade. If the
transmission is not shifted down,
the brakes might have to be used
so much that they would get hot and
no longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
will boil at a lower temperature than
at normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle may show
signs similar to engine overheating.To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 9‑20.
Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do
not shift into P (Park) yet. Turn
the wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Vehicle Care 9-11
What Kind of Engine Oil to Use
Look for three things:
.GM6094M
Use only an oil that meets GM
Standard GM6094M.
.SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use other
viscosity oils such as
SAE 20W-50.
.American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been certified by the American
Petroleum Institute (API).
Notice: Use only engine oil
identified as meeting GM
Standard GM6094M and showing
the American Petroleum Institute
Certified For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty. Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below
−29°C
(−20°F), 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
specification, GM6094M.
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the starburst
symbol that meet GM standards
are all that is needed for good
performance and engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
9-12 Vehicle Care
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. 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 Engine Oil
Soon” message comes on.
See Engine Oil Messages
on
page 4‑31. Change the oil as soon as possible within the next 1 000 km
(600 miles). 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 filter 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 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the vehicle has Driver Information
Center (DIC) buttons:
1. Turn the ignition to ON/RUN, with the engine off.
2. Press the DIC menu button until “Remaining Oil Life” displays.
3. Press and hold the set/clear button until “100%”is displayed.
4. Turn the key to LOCK/OFF.
The system is reset when the
“Change Engine Oil Soon” message
goes off.
Vehicle Care 9-17
What to Use
{WARNING
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
fire 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
−37°C (−34°F), outside
temperature.
.Gives boiling protection up to
129°C (265°F), 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.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
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 COLD FILL line, 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 Cooling System
on
page 9‑15for more information.
The coolant surge tank is located in
the engine compartment on the
driver side of the vehicle. See
Engine Compartment Overview
on
page 9‑6for more information on
location.
