260 Vehicle Care
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 jump start positive (+) terminal
is under a trim cover. You should
always use this remote positive (+)
terminal.
The jump start negative (–) ground
post is on the driver side shock
tower.
These locations are used instead of
a direct connection to the battery.
1. Jump Start Positive (+) Terminal
2. Jump Start Negative (–) Grounding Post
1. Check the other vehicle. It must have a 12-volt battery
with a negative ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting. 2. Position the two vehicles so
that they are not touching.
3. To avoid the possibility of the vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking
brake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
4. Turn the ignition off and switch off all lights and accessories in
both vehicles, except the
hazard warning flashers if
needed.
