CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.

WASHING THE EXTERIOR
Wash your vehicle regularly with cool or lukewarm water and a neutral
Ph shampoo, such as Motorcraft Detail Wash (ZC-3–A), which is available
from your dealer.
•Never use strong household detergents or soap, such as dish washing
or laundry liquid. These products can discolor and spot painted
surfaces.
•Never wash a vehicle that is“hot to the touch”or during exposure to
strong, direct sunlight.
•Always use a clean sponge or car wash mitt with plenty of water for
best results.
•Dry the vehicle with a chamois or soft terry cloth towel in order to
eliminate water spotting.
•It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle’s
paintwork and trim over time.
•Remove any exterior accessories, such as antennas, before entering a
car wash.
•Suntan lotions and insect repellents can damage any painted
surface; if these substances come in contact with your vehicle,
wash off as soon as possible.
WAXING
Applying a polymer paint sealant to your vehicle every six months will
assist in reducing minor scratches and paint damage.
•Wash the vehicle first.
•Do not use waxes that contain abrasives.
•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will“gray”or stain the parts over time.
PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.
