Vehicle Care
At least every spring, flush these
materials from the underbody with
plain water. Clean any areas where
mud and debris can collect. Dirt
packed in close areas of the frame
should be loosened before being
flushed. Your dealer or an
underbody car washing system can
do this.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts
such as fuel lines, frame, floor pan,
and exhaust system even though
they have corrosion protection.

Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can fall
upon and attack painted surfaces on
the vehicle. This damage can take
two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Although no defect in the paint job
causes this, we will repair, at no
charge to the owner, the surfaces of
new vehicles damaged by this
fallout condition within 12 months or
20 000 km (12,000 miles) of
purchase, whichever occurs first.
Interior Care
The vehicle's interior will continue to
look its best if it is cleaned often.
Although not always visible, dust
and dirt can accumulate on the
upholstery. Dirt can damage
carpet, fabric, leather, and plastic
surfaces. Regular vacuuming is
recommended to remove particles
from the upholstery. It is important to
keep the upholstery from becoming
and remaining heavily soiled. Soils
should be removed as quickly as
possible. The vehicle's interior may
experience extremes of heat that
could cause stains to set rapidly.
Lighter colored interiors may require
more frequent cleaning. Use care
because newspapers and garments
that transfer color to home
furnishings may also transfer color
to the vehicle's interior.
When cleaning the vehicle's interior,
only use cleaners specifically
designed for the surfaces being
cleaned. Permanent damage may
result from using cleaners on
surfaces for which they were not
intended. Use glass cleaner only on
glass. Remove any accidental
over-spray from other surfaces
immediately. To prevent over-spray,
apply cleaner directly to the
cleaning cloth.
