REFUELING IN EMERGENCY
The vehicle is equipped with a refueling funnel
Ú page 311 for a Cap-Less Fuel System. If
refueling is necessary, while using an approved
gas can, please insert the refueling funnel into the
filler neck opening.

Refueling Funnel

WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery. The
resulting electrical spark could cause the battery
to explode and could result in personal injury.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle
engine.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.

SERVICING AND MAINTENANCE353
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.

Blade Fuses

compartment, take care not to directly hit the
fuse box, and the windshield wiper motor with
water.
CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the power
distribution center and possibly result in an
electrical system failure.
