Vehicle Care 281
Interior Care
To prevent dirt particle abrasions, regularly
clean the vehicle's interior. Before using
cleaners, read and follow all safety
instructions on the label. While cleaning the
interior, open the doors and windows to get
proper ventilation. Newspapers or dark
garments can transfer color to the vehicle’s
interior.
Caution
Immediately remove cleaners, hand
lotions, sunscreen, and insect repellent
from all interior surfaces or permanent
damage may result.
Caution
Use cleaners specifically designed for the
surfaces being cleaned to prevent
permanent damage to the vehicle. Apply
all cleaners directly to a cleaning cloth.
Do not spray cleaners on any switches or
controls.
When using liquid soap cleaners, follow the
directions on the specific cleaner or soap
solution for dilution instructions.
Caution
To prevent damage:
.Never use a razor or any other sharp
object to remove soil from any interior
surface
.Never use a brush with stiff bristles.
.Never rub any surface aggressively or
with too much pressure.
.Do not get any exposed electrical
components wet.
.Do not use laundry detergents or
dishwashing soaps with degreasers. Do
not use solutions that contain strong
or caustic soap.
.Do not heavily saturate the upholstery
when cleaning.
.Do not use solvents or cleaners
containing solvents.
.Do not use disinfecting wipes that are
scented or contain bleach. Do not use
wipes or cleaners that show a color
transfer to the wipe or change the
appearance of the interior surface
when used.
(Continued)
Caution (Continued)
.Do not use scented or gel-type hand
sanitizers. If hand sanitizer comes in
contact with interior surfaces of the
vehicle, blot immediately and clean
with a soft cloth dampened with a
mild soap and water solution.
Interior Glass
To clean, use a microfiber cloth fabric
dampened with water. Wipe droplets left
behind with a clean dry cloth. If necessary,
use a commercial glass cleaner after
cleaning with plain water.
Caution
To prevent scratching, never use abrasive
cleaners on automotive glass. Abrasive
cleaners or aggressive cleaning may
damage the rear window defogger.
Cleaning the windshield with water during
the first three to six months of ownership
will reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover gently, so
that the speaker will not be damaged. Clean
spots with water and mild soap.

maintenance needs vary. There may need to
be more frequent checks and services. The
Additional Required Services - Normal are for
vehicles that:
.Carry passengers and cargo within
recommended limits on the Tire and
Loading Information label. SeeVehicle
Load Limits 0159.
.Are driven on reasonable road surfaces
within legal driving limits.

Recommended Fuel 0202.
Refer to the information in the Maintenance
Schedule Additional Required Services -
Normal chart.
The Additional Required Services - Severe are
for vehicles that are:
.Mainly driven in heavy city traffic in hot
weather.
.Mainly driven in hilly or mountainous
terrain.
.Frequently towing a trailer.
.Used for high speed or competitive
driving.
.Used for taxi, police, or delivery service. Refer to the information in the Maintenance
Schedule Additional Required Services -
Severe chart.
{Warning
Performing maintenance work can be
dangerous and can cause serious injury.
Perform maintenance work only if the
required information, proper tools, and
equipment are available. If they are not,
see your dealer to have a trained
technician do the work. See
Doing Your
Own Service Work 0215.
Maintenance Schedule
Tire Rotation and Required Services
Every 12 000 km (7,500 mi)
Tires are rotated to achieve a more uniform
wear for all tires. The first rotation is the
most important.
Anytime unusual wear is noticed, rotate the
tires as soon as possible, check for proper
tire inflation pressure, and check for
damaged tires or wheels. If the unusual
wear continues after the rotation, check the wheel alignment. See
When It Is Time for
New Tires 0260 and
Wheel Replacement 0263.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 288.
.Lubricate body components. See Exterior
Care 0277.
Additional Required Services —Normal
Service
Every 12 000 km (7,500 mi)
.Check engine oil level and oil
life percentage. If needed, change engine
oil and filter, and reset oil life system. Or
when the CHANGE ENGINE OIL SOON
message displays, have the engine oil and
filter changed within the next 1 000 km
(600 mi). If driven under the best
conditions, the engine oil life system may
not indicate the need for vehicle service
for up to a year. The engine oil and filter
must be changed at least once a year and
the oil life system must be reset. Your
trained dealer technician can perform this
work. If the engine oil life system is reset
accidentally, service the vehicle within
5 000 km (3,000 mi) since the last service.

Service and Maintenance 287
Reset the oil life system when the oil is
changed. SeeEngine Oil Life System
0 223.
.When the REPLACE AT NEXT OIL CHANGE
message displays, the engine air filter
should be replaced at the next engine oil
change. When the REPLACE ENGINE AIR
FILTER SOON message displays, the
engine air filter should be replaced at the
earliest convenience. Reset the engine air
filter life system after the engine air filter
is replaced. See Engine Air Filter Life
System 0224.
Every 36 000 km (22,500 mi)
.Passenger compartment air filter
replacement (or every 24 months,
whichever occurs first). More frequent
replacement may be needed if the vehicle
is driven in areas with heavy traffic, poor
air quality, areas with high dust levels or
are sensitive to environmental allergens.
Filter replacement may also be needed if
you notice reduced airflow, windows
fogging up, or odors. Your local GM
Service location can help you determine
when it is the right time to replace your
filter. Every 96 000 km (60,000 mi)
.Replace spark plugs. Inspect spark plug
wires and/or boots.

.Change rear axle fluid, if equipped with
AWD. Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced.
.Drain and fill engine cooling system. Or
every six years, whichever comes first.
See Cooling System 0226.
.1.2L L3 LIH Engine —Replace the timing
belt, timing belt tensioner, and oil pump.
