Explanation of General
Maintenance Items
Additional information on the
following items with * is found under
“Vehicle Checks” in the Vehicle
Care section of this manual. Outside the Vehicle
The maintenance items listed here
should be performed from time to
time, unless otherwise specified.
Doors and engine hood* :
Check
that the doors and engine hood
operate properly. Also ensure that
all latches lock securely. Lubricate
hinges, latches, latch pins, rollers,
and links if necessary.
Make sure that the secondary latch
keeps the hood from opening when
the primary latch is released.
When driving in areas using road
salt or other corrosive materials,
check lubrication frequently.
Lamps* : Clean the headllamps on
a regular basis. Make sure that the
headlamps, stoplamps, taillamps,
turn signal lamps, and other lights
are all operating properly and
installed securely. Also check
headlamp aim. Road wheel nuts (lug nuts) :
When checking the tires, make sure
no wheel nuts are missing, and
check for any loose wheel nuts.
Tighten if necessary.
Tire rotation* :
Tires should be
rotated every 8 000 km (5,000 mi).
Tires* : Check the pressure with a
gauge often and always prior to long
distance trips. If necessary, adjust
the pressure in all tires, including
the spare, to the pressure specified.
Check carefully for damage, cuts,
or excessive wear.
Tire Pressure Monitoring System
(TPMS) transmitter components :
Replace the TPMS transmitter
grommet seal, valve core, and cap
when the tires are replaced due to
wear or age.
Wheel alignment and balance : If
the vehicle pulls to either side while
driving on a straight and level road,
or if you detect uneven or abnormal
tire wear, there may be a need for
wheel alignment. If the steering

Windshield wiper and washer* :
Check that the wipers and washer
operate properly and that the wipers
do not streak.
Under the Hood and Vehicle
The maintenance items listed here
should be checked periodically (for
example, each time you check the
engine oil or refuel).
Battery* :Check the fluid level in
each cell. The fluid should be at the
bottom of the filler opening. Vehicles
operated in high temperatures or
under severe conditions require
frequent checks of the battery fluid
level.
Care should be taken to avoid
situations that can lead to potential
battery discharge and potential
no-start conditions such as:
. Installation or extended use of
electronic accessories that
consume battery power when
the engine is not running (phone
chargers, GPS, DVD
players, etc.). .
Vehicle is not driven regularly
and/or only driven short
distances.
In these cases, the battery may
need to be charged to maintain
battery health.
Brake fluid level* : Make sure that
the brake fluid level is between the
MAX and MIN lines on the reservoir.
Engine coolant level* : Check the
coolant level when the engine
is cold.
Engine drive belts : Make sure the
drive belts are not frayed, worn,
cracked, or oily.
Engine oil level* : Check the level
after parking the vehicle on a level
spot and turning off the engine. Wait
more than 15 minutes for the oil to
drain back into the oil pan.
Exhaust system : Make sure there
are no loose supports, cracks,
or holes. If the sound of the exhaust
seems unusual or there is a smell of
exhaust fumes, immediately have
the exhaust system inspected. It is
recommended that you see your dealer for this service. For additional
information, see
Engine Exhaust
0 149.
Fluid leaks : Check under the
vehicle for fuel, oil, water, or other
fluid leaks after the vehicle has
been parked for a while. Water
dripping from the air conditioner
after use is normal. If you notice any
leaks or if fuel fumes are evident,
check for the cause and have it
corrected immediately.
Radiator and hoses : Check the
front of the radiator and clean off
any dirt, insects, leaves, etc., that
may have accumulated. Make sure
the hoses have no cracks,
deformation, rot, or loose
connections.
Underbody : The underbody is
frequently exposed to corrosive
substances such as those used on
icy roads or to control dust. It is very
important to remove these
substances, otherwise rust may
form on the floor pan, frame, fuel
lines, and around the exhaust
system. At the end of winter, the
underbody should be thoroughly

Schedule
Explanation of Scheduled
Maintenance Items
The following descriptions are
provided to give you a better
understanding of the scheduled
maintenance items that should be
regularly checked or replaced. The
maintenance schedule indicates at
which mileage/time intervals each
item requires service.
In addition to scheduled
maintenance, your vehicle requires
that some items be checked during
normal day-to-day operation. For
additional information, refer to
“General Maintenance” in this
section.
Items marked with * are
recommended for reliable vehicle
operation. You are not required to
perform maintenance on these
items in order to maintain the
warranties that come with your
vehicle. Other maintenance items
and intervals are required. When applicable, additional
information can be found under

Chevrolet does not advocate the
use of non-OEM approved
aftermarket flushing systems and
strongly advises against performing
these services on a Chevrolet
product. Many of the aftermarket
flushing systems use non-OEM
approved chemicals or solvents, the
use of which has not been validated
by Chevrolet.

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
