electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.
Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
The vehicle has a battery cover
which must be removed to gain
access to the battery for jump
starting.
1. Clips
2. Pivot Points
To remove the battery cover: 1. Release the two rear clips (1).
2. Lift the battery cover up toward the front of the vehicle to
release it from the pivot
points (2) and remove.
3. Reverse Steps 1 and 2 to reinstall the battery cover.
The vehicle has a remote
positive (+) terminal under a trim
cover. It is under the battery cover
on the driver side of the engine
compartment. See Engine
Compartment Overview 0231. You
should always use this remote
positive terminal.
The jump start negative grounding
point for the discharged battery is
the engine block or an engine
mounting bolt. Connect to a spot as
far away from the discharged
battery as possible.
1. Check the other vehicle. It must have a 12-volt battery
with a negative ground system.

Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{Warning
