248 Service and Maintenance
Maintenance Schedules
To help ensure smooth, safe, and
economical driving, two
maintenance schedules are
provided, depending upon the
conditions in which you usually
drive. These schedules contain both
distance and time intervals, up to
160 000 km (100,000 mi)/
120 months. For most people, the
odometer reading will indicate when
service is needed. However, if you
drive very little, your vehicle should
be serviced at the regular time
intervals shown in the schedule.
After 160 000 km (100,000 mi)/
120 months, continue maintenance
at the same mileage/time intervals.
Additional Maintenance Items for
Severe Operating Conditions
Additional maintenance items for
severe operating conditions should
be performed on vehicles that are
driven under especially demanding
conditions. Additional maintenanceitems should be performed if you
primarily operate your vehicle under
the following conditions:
.
Repeated short trips of less than
8 km (5 mi).
. Repeated short trips of less than
16 km (10 mi) with outside
temperatures remaining below
freezing.
. Operating in hot weather in
stop-and-go “rush hour”traffic.
. Extensive idling and/or low
speed driving for long distances,
such as police, taxi,
or door-to-door delivery use.
. Driving in dusty conditions.
. Driving on rough, muddy, or salt
spread roads.
. Using a car-top carrier.
For vehicles operated in Canada,
both standard and severe
maintenance items should be
performed at every interval.
Standard Maintenance
The following tables show the
standard maintenance schedule.
Depending upon weather and
atmospheric conditions, varying
road surfaces, individual driving
habits, and vehicle usage, additional
or more frequent maintenance may
be required. After 160 000 km
(100,000 mi)/120 months, continue
maintenance at the same mileage/
time interval.

System Maintenance
(1) After 64 000 km (40,000 mi) or
48 months, inspect every 16 000 km
(10,000 mi) or 12 months. Replace
the drive belts if found damaged.
(2) If operating mainly in dusty
conditions, more frequent
maintenance may be required.
(3) Periodic maintenance is not
required.
(4) First replacement interval is
168 000 km (105,000 mi) or
84 months. After first replacement,
replace every 120 000 km
(75,000 mi) or 60 months. (5)
Use only prediluted ACDelco CE
Long Life Antifreeze Coolant (blue)
or equivalent. Mixing any other type
of coolant or using non-distilled
water may reduce the life
expectancy of the factory fill coolant.
See Recommended Fluids and
Lubricants 0257.
(6) Replace spark plug when the
plug gap exceeds 1.4 mm (0.055 in)
even if within specified periodic
replacement mileage.
(7) Periodic maintenance is not
required. However, if valve noise
increased, inspect valve clearance. * Maintenance items and intervals
with * are recommended for reliable
vehicle operation. The owner need
not perform such maintenance in
order to maintain the emission
warranty or manufacturer recall
liability. Other maintenance items
and intervals are required.

Maintenance
Maintenance items with ∞should be
performed more frequently
according to “Maintenance Under
Severe Operating Conditions”.
(1) If towing a trailer, using a
camper or a car-top carrier,
or driving on rough or muddy roads,
inspect CVT fluid deterioration at
your dealer every 96 000 km
(60,000 mi), then change CVT fluid
if necessary. And if the inspection is
not performed, change (not just
inspect) CVT fluid every 96 000 km
(60,000 mi).
(2) Refer to “Tire Rotation” under
“Explanation of Scheduled
Maintenance Items” earlier in this
section.Maintenance Under Severe
Operating Conditions
The maintenance intervals shown
on the preceding pages are for
normal operating conditions. If the
vehicle is mainly operated under
severe driving conditions as shown
below, more frequent maintenance
must be performed on the following
items as shown in the table.
Severe Driving Conditions
. Repeated short trips of less than
8 km (5 mi).
. Repeated short trips of less than
16 km (10 mi) with outside
temperatures remaining below

Additional
Maintenance and Care
Your vehicle is an important
investment and caring for it properly
may help to avoid future costly
repairs. To maintain vehicle
performance, additional
maintenance services may be
required.
It is recommended that your dealer
perform these services —their
trained dealer technicians know
your vehicle best. Your dealer can
also perform a thorough
assessment with a multi-point
inspection to recommend when your
vehicle may need attention.
The following list is intended to
explain the services and conditions
to look for that may indicate
services are required. Battery
The 12-volt battery supplies power
to start the engine and operate any
additional electrical accessories.
.
To avoid break-down or failure to
start the vehicle, maintain a
battery with full cranking power.
. Trained dealer technicians have
the diagnostic equipment to test
the battery and ensure that the
connections and cables are
corrosion-free.
Belts
. Belts may need replacing if they
squeak or show signs of
cracking or splitting.
. Trained dealer technicians have
access to tools and equipment
to inspect the belts and
recommend adjustment or
replacement when necessary.

Service and Maintenance 255
Brakes
Brakes stop the vehicle and are
crucial to safe driving.
.Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping.
. Trained dealer technicians have
access to tools and equipment
to inspect the brakes and
recommend quality parts
engineered for the vehicle.
Fluids
Proper fluid levels and approved
fluids protect the vehicle’s systems
and components. See
Recommended Fluids and
Lubricants 0257 for GM approved
fluids.
. Engine oil and windshield
washer fluid levels should be
checked at every fuel fill.
. Instrument cluster lights may
come on to indicate that fluids
may be low and need to be
filled. Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi-point inspection, your
dealer can inspect the hoses and
advise if replacement is needed.
Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.
Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
. With a multi-point inspection,
your dealer can check the lamps
and note any concerns. Shocks and Struts
Shocks and struts help aid in control
for a smoother ride.
.
Signs of wear may include
steering wheel vibration, bounce/
sway while braking, longer
stopping distance, or uneven
tire wear.
. As part of the multi-point
inspection, trained dealer
technicians can visually inspect
the shocks and struts for signs
of leaking, blown seals,
or damage, and can advise
when service is needed.
Tires
Tires need to be properly inflated,
rotated, and balanced. Maintaining
the tires can save money and fuel,
and can reduce the risk of tire
failure.
. Signs that the tires need to be
replaced include three or more
visible treadwear indicators; cord
or fabric showing through the
