308 Vehicle Care
Caution
Avoid using high-pressure washes closer
than 30 cm (12 in) to the surface of the
vehicle. Use of power washers exceeding
8 274 kPa (1,200 psi) can result in
damage or removal of paint and decals.
If using an automatic car wash, follow the
car wash instructions. The windshield wiper
and rear window wiper, if equipped, must
be off. Remove any accessories that may be
damaged or interfere with the car wash
equipment.
Rinse the vehicle well, before washing and
after, to remove all cleaning agents
completely. If they are allowed to dry on
the surface, they could stain.
Dry the finish with a soft, clean chamois or
an all-cotton towel to avoid surface
scratches and water spotting.
Cleaning Underhood Components
Caution
Do not power wash any component
under the hood that has this
e
symbol.(Continued)
Caution (Continued)
This could cause damage that would not
be covered by the vehicle warranty.
Solvents or aggressive cleaners may harm
underhood components. The usages of these
chemicals should be avoided.
Recommend water only.
A pressure washer may be used, but care
must be utilized. The following criteria must
be followed:
.Water pressure must be kept below
14 000 KPa (2,000 PSI).
.Water temperature must be below 80 °C
(180 °F).
.Spray nozzle with a 40 degree wide angle
spray pattern or wider must be used.
.Nozzle must be kept at least 30 cm (1 ft)
away from all surfaces.
Finish Care
Application of aftermarket clearcoat sealant/
wax materials is not recommended.
If painted surfaces are damaged, see your
dealer to have the damage assessed and
repaired. Foreign materials such as calcium
chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can
damage the vehicle's finish if they remain
on painted surfaces. Wash the vehicle as
soon as possible. If necessary, use
non-abrasive cleaners that are marked safe
for painted surfaces to remove foreign
matter.
Occasional hand waxing or mild polishing
should be done to remove residue from the
paint finish. See your dealer for approved
cleaning products.
Do not apply waxes or polishes to uncoated
plastic, vinyl, rubber, decals, simulated
wood, or flat paint as damage can occur.
Caution
Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
finish may damage it. Use only
non-abrasive waxes and polishes that are
made for a basecoat/clearcoat paint finish
on the vehicle.
To keep the paint finish looking new, keep
the vehicle garaged or covered whenever
possible.

Vehicle Care 313
.For solid soils, remove as much as
possible prior to vacuuming.
To clean: 1. Saturate a clean, lint-free colorfast cloth with water. Microfiber cloth is
recommended to prevent lint transfer to
the fabric or carpet.
2. Remove excess moisture by gently wringing until water does not drip from
the cleaning cloth.
3. Start on the outside edge of the soil and gently rub toward the center. Fold the
cleaning cloth to a clean area frequently
to prevent forcing the soil into the
fabric.
4. Continue gently rubbing the soiled area until there is no longer any color
transfer from the soil to the cleaning
cloth.
5. If the soil is not completely removed, use a mild soap solution followed only
by plain water.
If the soil is not completely removed, it may
be necessary to use a commercial upholstery
cleaner or spot lifter. Test a small hidden
area for colorfastness before using a commercial upholstery cleaner or spot lifter.
If ring formation occurs, clean the entire
fabric or carpet.
After cleaning, use a paper towel to blot
excess moisture.
Cleaning High Gloss Surfaces and Vehicle
Information and Radio Displays
Use a microfiber cloth on high gloss surfaces
or vehicle displays. First, use a soft bristle
brush to remove dirt that can scratch the
surface. Then gently clean by rubbing with a
microfiber cloth. Never use window cleaners
or solvents. Periodically hand wash the
microfiber cloth separately, using mild soap.
Do not use bleach or fabric softener. Rinse
thoroughly and air dry before next use.
Caution
Do not attach a device with a suction cup
to the display. This may cause damage
and would not be covered by the vehicle
warranty.
Instrument Panel, Leather, Vinyl, Other
Plastic Surfaces, Low Gloss Paint
Surfaces, and Natural Open Pore Wood
Surfaces
Use a soft bristle brush to remove dust from
knobs and crevices on the instrument
cluster. Use a soft microfiber cloth
dampened with water to remove dust and
loose dirt. For a more thorough cleaning,
use a soft microfiber cloth dampened with a
mild soap and water solution.
Caution
Soaking or saturating leather, especially
perforated leather, as well as other
interior surfaces, may cause permanent
damage. Wipe excess moisture from
these surfaces after cleaning and allow
them to dry naturally. Never use heat,
steam, or spot removers. Do not use
liquids that contain alcohol or solvents on
leather seats. Do not use cleaners that
contain silicone or wax-based products.
Cleaners containing these solvents can
permanently change the appearance and
feel of leather or soft trim, and are not
recommended.

General Information
Your vehicle is an important investment.
This section describes the required
maintenance for the vehicle. Follow this
schedule to help protect against major repair
expenses resulting from neglect or
inadequate maintenance. It may also help to
maintain the value of the vehicle if it is
sold. It is the responsibility of the owner to
have all required maintenance performed.
Your dealer has trained technicians who can
perform required maintenance using genuine
replacement parts. They have up-to-date
tools and equipment for fast and accurate
diagnostics. Many dealers have extended
evening and Saturday hours, courtesy
transportation, and online scheduling to
assist with service needs.
Your dealer recognizes the importance of
providing competitively priced maintenance
and repair services. With trained technicians,
the dealer is the place for routine
maintenance such as oil changes and tire
rotations and additional maintenance items
like tires, brakes, batteries, and wiper blades.
Caution
Damage caused by improper maintenance
can lead to costly repairs and may not be
covered by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids, and
lubricants are important to keep the
vehicle in good working condition.
Do not have chemical flushes that are not
approved by GM performed on the
vehicle. The use of flushes, solvents,
cleaners, or lubricants that are not
approved by GM could damage the
vehicle, requiring expensive repairs that
are not covered by the vehicle warranty.
The Tire Rotation and Required Services are
the responsibility of the vehicle owner. It is
recommended to have your dealer perform
these services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to keep
the vehicle in good working condition,
improves fuel economy, and reduces vehicle
emissions.

{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 0247.
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 0290 and
Wheel Replacement 0294.
.Perform Multi-Point Vehicle Inspection.
See Multi-Point Vehicle Inspection (MPVI)
0 319.
.Lubricate body components. See Exterior
Care 0307.
Additional Required Services —Normal
Service
Every 12 000 km (7,500 mi)
.Check the engine oil level and oil
life percentage. If needed, change engine
the oil and filter, and reset oil the 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.
