1997 PONTIAC BONNEVILLE service interval

When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even
when they’re underinflated.
Be sure to put
the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,080 to 8,000 miles
(10 000 to 13 000 h). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires’’
and
“Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
unifQm
wear .- - for .. dl tires ., on . h .. vehicle. . The first rotation
is the most important. See “Scheduled
Maintenance Services” in the Index 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 inflation pressures
as shown on the Tire-Loading
Information label.
Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in
the Index.

Maintenance Schedule
1 Short Trip/City Definition I
Follow the Short Trip/City Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 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).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule
if you operate your vehicle under any of these
conditions is that these conditions cause engine
oil to break down sooner.

-f- The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion
of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides
and underbody contact points and linkage.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection” in Part
C of this schedule.
++ If you drive in a highly corrosive environment,
your brake calipers may require additional
inspection and service, at every other tire rotation.
See “Caliper/Knuckle Maintenance Inspection”
