2010 GMC TERRAIN maintenance

9-88 Vehicle Care
Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean the rubber blades using a lint
free cloth or paper towel soaked
with windshield washer fluid or a
mild detergent. Wash the windshield
thoroughly when cleaning the
blades. Bugs, road grime, sap, and
a buildup of vehicle wash/wax
treatments may cause wiper
streaking. Replace the wiper blades
if they are worn or damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper
removal
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Notice:Using petroleum-based
tire dressing products on the
vehicle may damage the paint
finish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired right away. Bare metal will
corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer/retailer.
Larger areas of finish damage can
be corrected in your dealer's/
retailer's body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts
such as fuel lines, frame, floor pan,
and exhaust system even though
they have corrosion protection.

General Information
Notice: Maintenance intervals,
checks, inspections,
recommended fluids, and
lubricants are necessary to keep
this vehicle in good working
condition. Damage caused by
failure to follow scheduled
maintenance might not be
covered by the vehicle warranty.
As the vehicle owner, you are
responsible for the scheduled
maintenance in this section. We
recommend having your dealer/
retailer perform these services.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality. Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under
Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer/retailer.
The maintenance schedule is for
vehicles that:
.Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See
Vehicle Load Limits
on page 8‑22.
.Are driven on reasonable road
surfaces within legal driving
limits.

10-2 Service and Maintenance
.Are driven off-road in the
recommended manner. See
Off-Road Driving on page 8‑7.

be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer/
retailer to have a qualified

fluids, and lubricants to use are
listed in
Recommended Fluids and
Lubricants
on page 10‑7and
Maintenance Replacement Partson
page 10‑9. We recommend the use
of genuine parts from your dealer/
retailer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). See Tire
Rotation on page 9‑58.
Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter. See
Engine Oilon page 9‑10. An
Emission Control Service.
When the Change Engine Oil
Soon message displays, service
is required for the vehicle as
soon as possible, within the next
1 000 km/600 miles. If driving under
the best conditions, the engine oil
life system might not indicate the
need for vehicle service for more
than a year. The engine oil and filter
must be changed at least once a
year and the oil life system must
be reset. Your dealer/retailer has
trained service technicians who
will perform this work and reset
the system. If the engine oil life

system is reset accidentally,
service the vehicle within
5 000 km/3,000 miles since the
last service. Reset the oil life
system whenever the oil is changed.
SeeEngine Oil Life System
on
page 9‑12.
