298 VEHICLE CARE
Insects, road grime, sap, and a
build-up of vehicle wash/wax
treatments may cause wiper streaking.
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 0 305.
Tyres
Use a stiff brush with tyre cleaner to
clean the tyres.
Caution
Using petroleum-based tyre
dressing products on the vehicle
may damage the paint finish and/or
tyres. When applying a tyre
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
Caution (Continued)
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
