3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
4. Open the bonnets and locate the
positive (+) and negative (-)
terminal locations or the remote
positive (+) and remote
negative (-) terminals of the
other vehicle. Then locate the
remote positive (+) location on
your vehicle. See Engine
Compartment Overview on
page 10 5 for locations of the
terminals.
Your vehicle has a remote
negative (-) ground location, as
shown in the illustration. It is on
the left side of the engine
compartment. See Engine
Compartment Overview on
page 10 5. You should always
use this remote ground location,
instead of the terminal on the
battery.
Notice: If you connect a negative
cable to the Engine Control
Module (ECM), ECM mounting
bracket or any cables that attach
to the ECM bracket, you may
damage the ECM. Always attach
the negative cable to your
vehicle's remote negative ground
location, instead of the ECM, ECM
bracket or any cables attached to
the ECM bracket.
WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underbonnet electric fan.
