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
0230.
Always use this remote positive
terminal.
The vehicle has a remote negative
(−) ground location. It is located on
the driver side of the engine
compartment. See Engine
Compartment Overview 0230.
Always use this remote ground
location, instead of the terminal on
the battery.
These posts are used instead of a
direct connection to the battery.
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. Set the parking brake firmly. Vehicles with an automatic
transmission should be in
P (Park). See Shifting Into Park

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.

If your vehicle has an Oil Life
Indicator, the indicator will show
you when to change the oil and
filter. Under severe conditions
the indicator may come on
before 10 000 km/6,000 mi. The
indicator won't detect dust in the
oil, so if you drive in a dusty
area you may have to change
the oil and filter sooner than
every 10 000 km/6,000 mi.
Note: All vehicles with
rear-wheel drive —change
driveline axle oil every
30 000 km/19,000 mi if vehicle is
used for towing purposes. * Footnote: Under extreme
driving conditions listed above, it
may be necessary to replace
your spark plugs at more
frequent intervals. For further
assistance in determining the
most suitable service
maintenance intervals for your
vehicle, please contact your
authorized GM Dealer.
