Engine Oil Life System
When to Change Engine Oil
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 OIL SOON message will come
on. SeeDIC Warnings and Messages on page 3-69.
Change your oil as soon as possible within the next
600 miles (1 000 km). 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 service
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.How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle use.
Anytime your oil is changed, reset the system so it
can calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE OIL SOON message appearing on the
DIC, reset the system.
To reset the oil life system, after the oil has been
changed, use the following procedure:
1. Press the options button on the DIC until ENGINE
OIL MONITOR appears on the DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the engine oil
monitor system has been reset.
If the vehicle is equipped with the trip computer
DIC, when the gage button is pressed and the OIL
LIFE REMAINING mode appears, it should read
100 percent OIL LIFE REMAINING.
3. Turn the key to OFF.

Checking Coolant
The coolant recovery tank is located in the engine
compartment toward the rear of the engine on
the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location.
The vehicle must be on a level surface when checking
the coolant level.
When the engine is cold,
the coolant level should be
at the COLD mark or a
little higher.
When the engine is warm, the level should be up to the
HOT mark or a little higher.
Adding Coolant
This symbol, along with
the LOW COOLANT
LEVEL warning message
comes on in the Driver
Information Center
(DIC) when coolant needs
to be added to the
coolant recovery tank.
SeeDIC Controls and Displays (Base Level DIC) on
page 3-49orDIC Controls and Displays (Uplevel
DIC with Trip Computer) on page 3-57for more
information.
If more coolant is needed, add the proper DEX-COOL
®
coolant mixture at the coolant recovery tank, but be
careful not to spill it.
If the coolant recovery tank is completely empty, add
coolant to the radiator. SeeEngine Overheating
on page 5-27.

The tire ination monitor system will not alert you if the
pressure in more than one tire is low, if the system
is not properly calibrated, or if the vehicle is moving
faster than 70 mph (110 km/h).
When the CHECK TIRE PRESSURE warning message
comes on, stop as soon as possible and check all
the tires for damage. If a tire is at, seeIf a Tire Goes
Flat on page 5-73. Also, check the tire pressure in
all four tires as soon as possible. SeeInation - Tire
Pressure on page 5-64.
The CHECK TIRE PRESSURE warning message will
also be displayed, while the ignition is on, until the
system is reset. To reset the system, see “Tire Ination
Monitor System” under the options mode inDIC
Controls and Displays (Base Level DIC) on page 3-49
orDIC Controls and Displays (Uplevel DIC with Trip
Computer) on page 3-57.
Do not reset the tire ination monitor system without
rst correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If the
system is reset when the tire pressures are incorrect,
the system will not work properly and may not respond
when a tire is low.The tire ination monitor system will need to be reset
any time a tire’s pressure is adjusted, the tires are
rotated, or one or more tires is repaired or replaced. The
system will also need to be reset when new tires are
purchased for the vehicle and when the battery
has been disconnected.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-68andWheel Replacement
on page 5-71for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4for scheduled rotation intervals.
