11-10 Service and Maintenance
Fluids
Proper fluid levels and approved
fluids protect the vehicle s
systems and components.
See Recommended Fluids and
Lubricants on page 11 12 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.
