(1) Or every two years, whichever
comes first. More frequent
passenger compartment air filter
replacement may be needed if
driving in areas with heavy traffic,
poor air quality, high dust levels,
or environmental allergens.
Passenger compartment air filter
replacement may also be needed if
there is reduced airflow, window
fogging, or odors. Your GM dealer
can help determine when to replace
the filter.
(2) Visually check all fuel and vapor
lines and hoses for proper
attachment, connection, routing, and
condition.
(3) Or every four years, whichever
comes first. If driving in dusty
conditions, inspect the filter at each
oil change or more often as needed.
See Engine Air Cleaner/Filter 0224.
(4) Or every three years, whichever
comes first. If the vehicle mileage is
near the canister filter replacement
interval, replace the fluid and filter. More frequent fluid and filter
replacement may be needed if the
vehicle is competitively or
aggressively driven. This service
can be complex. See your dealer.
(5)
Check the transmission fluid
life percentage. If the percentage is
less than 10%, replace the fluid and
filter. The initial transmission
canister filter change must be
performed at 12 000 km (7,500 mi),
and every 36 000 km (22,500 mi)
thereafter. This service can be
complex. See your dealer.
(6) Or every five years, whichever
comes first. See Cooling System

comes first. Inspect for fraying,
excessive cracking, or damage;
replace, if needed.

.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 0295 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
rubber; cracks or cuts in the
tread or sidewall; or a bulge or
split in the tire.
. Trained dealer technicians can
inspect and recommend the right
tires. Your dealer can also
provide tire/wheel balancing
services to ensure smooth
vehicle operation at all speeds.
Your dealer sells and services
name brand tires.
