Cleaning Wheels
Only use a recommended wheel and tire
cleaner to clean the wheels weekly. For
additional information and assistance, we
recommend that you contact an authorized
dealer.
1.
Use a sponge to remove heavy deposits
of dirt and brake dust.
2. Rinse well after cleaning.
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers.
If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before parking your vehicle.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers. Cleaning the Engine Compartment
Use a vacuum cleaner to remove debris from
the screen area below windshield.
Note:
If you are not familiar with the parts
around the engine do not wash the engine
compartment. Avoid frequent engine
washes.
When washing the engine compartment:
• Never wash or rinse the engine while it
is hot or running.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage.
Note: If your vehicle has an engine cover
remove the cover before application of
shampoo and degreaser.
• Spray an approved engine shampoo and
degreaser on all parts that require
cleaning and rinse with water. Cleaning Stripes or Graphics
It is recommended to wash your vehicle by
hand however, pressure washing may be
used under the following conditions:
•
Use a spray with a 40° wide spray angle
pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90° angle to your vehicle's
surface.
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than 179°F (82°C).
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Cleaning Camera Lenses and Sensors
We recommend that you only use lukewarm
or cold water and a soft cloth to clean the
camera lens and sensors.
Note: Do not pressure wash camera lens
and sensors.

PREPARING YOUR VEHICLE FOR
STORAGE
If you plan on storing your vehicle for 30
days or more, the following maintenance
recommendations ensures your vehicle stays
in good operating condition.
Under various conditions, long-term storage
may lead to degraded engine performance
or failure unless you use specific precautions
to preserve your vehicle.
General
•
Store all vehicles in a dry, ventilated
place.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and weather damage.
• Make sure all linkages, cables, levers and
pins under your vehicle are covered with
grease to prevent rust. •
Move vehicles at least 25 ft (7.5 m) every
15 days to lubricate working parts and
prevent corrosion.
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the fuel
pump nozzle.
Engine
• Change the engine oil and filter prior to
storage because used engine oil contains
contaminants which may cause engine
damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift through
all the gears while the engine is running. Body
•
Wash your vehicle thoroughly to remove
dirt, grease, oil, tar or mud from exterior
surfaces, rear-wheel housings and the
underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary when
you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with a
light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
