If engine runs hot
For troubleshooting information, refer to the engine operator's manual.
If fuses burn out
Burned-out or ªblown-outº fuses or circuit breaker tripping (if equipped)
usually indicate an electrical short circuit, although a fuse may
occasionally fail from vibration. Insert a second fuse or reset the breaker
(if equipped). If this fuse immediately burns out or the breaker (if
equipped) trips and you cannot locate the fuse, return your vehicle to
your dealer for a circuit check.
If lamp bulbs burn out
Repeated lamp burn-out usually indicates a loose connection, either at
the lamp socket, the system ground or a malfunctioning voltage
regulator. If examination does not indicate the cause of the trouble,
return your vehicle to your dealer for inspection.
If headlamps flash on and off
If headlamps flash on and off at regular intervals, the system circuit
breaker (if equipped) is operating, indicating a short circuit or overload.
Take your vehicle to your dealer for a circuit check.
CLEANING AND CARING FOR YOUR VEHICLE
Refer to the Customer Assistance chapter for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
