Warning
Follow the manufacturer's advice

cause personal injury or damage.

volatile cleaning solvents, such as
acetone, lacquer thinners, enamel
reducers, nail polish removers; or
such cleaning materials as
laundry soaps, bleaches or
reducing agents, except as noted
in the following fabric cleaning
advice on stain removal.
Never use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose. Open all
vehicle doors for ventilation when
ANY cleaning agents or other
chemicals are used in the interior.
Overexposure to some vapors
may result in a health problem
that is more likely to occur in
small, unventilated spaces.
You and others could be seriously
injured.
Do not apply water directly in order
to clean the cab interior. Failure to
observe this precaution can result in
malfunction or breakdown of
electronic control units and electrical
components, or in rusting of the cab
floor. Do not apply water from a
high-pressure washer nozzle
directly to the electric connectors.
Failure to observe this precaution
can lead to faulty operation of the
electrical system. If an automatic
car or truck-wash is used with
vehicles having dark or metallic
coating, the painted surfaces can be
damaged by the brushes, lose their
luster or be very noticeably
scratched.
Do not direct a large amount of
water at the air inlet openings. Do
not apply water to the engine
compartment or at electrical
components. Failure to observe this
precaution can lead to a poorly
starting and operating engine and
problems in the electrical system.
Ensure that mirrors and the antenna
are retracted before washing the
vehicle.
If an automatic car or truck-wash
must be used, avoid a
high-temperature, high pressure
type machine. Failure to observe
