and steering system for damaged, loose, or
missing parts or signs of wear. Inspect power
steering lines and hoses for proper hook-up,

constant velocity joints, rubber boots, and axle

with genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside

blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield
Wiper Blade Replacement on page 375and
Windshield and Wiper Blades on page 427for

(e)Make sure the safety belt reminder light and
all your belts, buckles, latch plates, retractors, and

other loose or damaged safety belt system parts.
If you see anything that might keep a safety
belt system from doing its job, have it repaired.

a problem. Have the system inspected and
repaired and the uid level checked. Add uid
if needed.
