When to Change Engine Oil (Vehicles
Without the Engine Oil Life System)
If any one of these is true for you, use the short trip/city
maintenance schedule:
Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
Most trips include extensive idling, such as frequent
driving in stop-and-go traffic.
You frequently tow a trailer or use a carrier on top
of your vehicle.
The vehicle is used for delivery service, police, taxi,
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and lter
every 3,000 miles (5 000 km) or 3 months — whichever
occurs rst.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and lter every
7,500 miles (12 500 km) or 12 months — whichever
occurs rst. Driving a vehicle with a fully warmed engine
under highway conditions will cause engine oil to
break down slower.
If your vehicle has the Engine Oil Life System, see
Engine Oil Life System on page 5-20for information on
when to change your engine oil.
Engine Oil Life System
When to Change Engine Oil
If your vehicle has the Engine Oil Life System, it 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. An ENGINE OIL CHANGE SOON DIC
message will come on. SeeDIC Warnings and
Messages on page 3-62. 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.

Check Tire Pressure System
The check tire pressure system can alert you to a
large change in the pressure of one tire. The system
will not alert you before you drive that a tire is low or
at. You must begin driving before the system will
work properly.
The CHECK TIRE PRESSURE message will appear on
the Driver Information Center (DIC) or the system
monitor TIRE PRESS light will come on if pressure
difference (low pressure) is detected in one tire.
The check tire pressure system may not alert you if:
More than one tire is low.
The vehicle is moving faster than
65 mph (105 km/h).
The system is not yet calibrated.
The compact spare tire is installed.
The tire treadwear is uneven.
Tire chains are being used.
The vehicle is being driven on a rough or
frozen road.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-42.The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire — but it does not replace normal tire
maintenance. SeeTires on page 5-74.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center (DIC) or the systems
monitor TIRE PRESS light comes on, you should
stop as soon as you can and check all your tires for
damage. If a tire is at, seeIf a Tire Goes Flat on
page 5-92. Also check the tire pressure in all four tires
as soon as you can. SeeInation - Tire Pressure
on page 5-80.
Any time you adjust a tire’s pressure or have one or
more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate
the tires, buy new tires and install or remove the
compact spare.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.
5-83

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 5-86andWheel Replacement
on page 5-89for 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. SeePart A: Scheduled
Maintenance Services on page 6-4, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label.
Reset the check tire pressure system, if equipped. See
Check Tire Pressure System on page 5-83.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-121.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. SeeChanging a Flat
Tire on page 5-93.
