2003 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS heater

Note:If the engine does not start within five seconds on the first try,
turn the key to 3 (OFF), wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -23° C (-10° F) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to the Scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
