Driving & Safety
SECTION THREE
to repair or replace the tire . In the case of sudden tire
failure, avoid heavy braking . Hold the steering wheel
firmly and gradually decrease speed . Slowly move to
a safe off-road place which should be a firm level spot .
Turn the ignition off and turn the hazard flashers on .
DEAD CHASSIS BATTERY
A discharged battery will not supply the amount of
amperage necessary to crank and start the engine .
If the engine fails to crank, or cranks slowly due to a
discharged chassis battery, the Battery Boost switch
will allow a temporary connection of the
house battery to the chassis battery to
increase amperage .
Battery Boost Switch:
The Battery Boost switch engages a heavy-
duty solenoid to electrically connect the
house batteries to the engine battery in the
event the engine will not crank or cranks
slowly . The solenoid is designed for short-term high
current intermittent use . Engaging the boost solenoid for
an extended period will damage the solenoid .
Jump Starting Using Battery Boost Switch:
• With ignition key Off, press and hold the Battery
Boost switch for ten seconds . After ten seconds,
continue to hold the switch and attempt to crank
the engine .
• If the engine fails to crank or does not crank fast
enough, discontinue the attempt . Continued
attempts will only diminish any remaining surface
charge in the chassis battery and end future
alternative attempts .
• Next, start the generator . This may require using the
Battery Boost switch for the generator to start from
the engine battery . Once the generator is operating,
the electrical combination of the generator and the
converter will charge the batteries .
• Allow the generator to run approximately hour
before attempting to crank the engine .
• Press the Battery Boost switch and attempt to
crank the engine .
• If the engine fails to crank, or does not crank fast
enough to start the engine, the chassis battery may
be depleted and the motorhome will require a jump
start or connect an external charger to the chassis
battery .
Jump Starting Using an External Source:
When using jumper cables to start the engine, the
cables must connect in a parallel configuration . That
is, positive (+) to positive and negative battery (-) to
negative chassis (-) . Always connect the positive (+)
before connecting the negative (-) . To prevent arcing
WARNING:
DO NOT crawl under the motorhome for any
reason if a wheel has been removed . Any number
of circumstances could cause the motorhome to
suddenly fall, resulting in severe injury or death .
