periodically to ensure that they
light when braking.

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.

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

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.
Vehicle Care

protect the vehicle’s interior and
exterior, see Interior Care 0384 and
Exterior Care 0380. Wheel Alignment

ensuring that the tires deliver optimal
wear and performance.
.

to be adjusted include pulling,
improper vehicle handling,
or unusual tire wear.
. Your dealer has the required
equipment to ensure proper wheel
alignment.
Windshield

viewing, keep the windshield clean
and clear.

cracks, and chips.

inspect the windshield and
recommend proper replacement if
needed.
