318 Vehicle Care
Replace the wiper blades if they are
worn or damaged. Damage can be
caused by extreme dusty
conditions, sand, salt, heat, sun,
snow, and ice.
Weatherstrips
Apply Dielectric silicone grease on
weatherstrips to make them last
longer, seal better, and not stick or
squeak. Lubricate weatherstrips at
least once a year. Hot, dry climates
may require more frequent
application. Black marks from
rubber material on painted surfaces
can be removed by rubbing with a
clean cloth. See Recommended
Fluids and Lubricants 0 328.
Tyres
Use a stiff brush with tyre cleaner to
clean the tyres.

dressing, always wipe off any
overspray from all painted
surfaces on the vehicle.
Wheels and Trim - Aluminium
or Chrome
Use a soft, clean cloth with mild
soap and water to clean the wheels.
After rinsing thoroughly with clean
water, dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and other chrome
trim may be damaged if the
vehicle is not washed after driving
on roads that have been sprayed
with magnesium, calcium,
or sodium chloride. These
chlorides are used on roads for
conditions such as ice and dust.
Always wash the chrome with
soap and water after exposure.
Caution
To avoid surface damage, do not
use strong soaps, chemicals,
abrasive polishes, cleaners,
brushes, or cleaners that contain
acid on aluminium or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminium or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tyre cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Brake System
Visually inspect brake lines and
hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and discs
for surface condition. Inspect drum
brake linings/shoes for wear or
cracks. Inspect other brake parts,
including drums, wheel cylinders,
callipers, parking brake, master
