Add-On Electrical
Equipment
Notice: Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
first. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle battery, even if the vehicle is
not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-35.
Headlamp Wiring
The headlamp wiring is protected
by fuses in the fuse block.
An electrical overload will cause the
lamps to turn off. If this happens,
have the headlamp wiring checked
right away.
