on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag and
knee airbag are allowed to inflate.

on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag and

indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the

light is working. It should go out when
the engine is started. For vehicles with

all accessories, such as the radio and
air conditioner.

the ignition is in Service Mode. See

Caution
If the jumper cables are connected
or removed in the wrong order,
electrical shorting may occur and
damage the vehicle. The repairs
would not be covered by the vehicle
warranty. Always connect and
remove the jumper cables in the
correct order, making sure that the
cables do not touch each other or
other metal.
Jumper Cable Removal

removing the jumper cables, allow it
to idle for several minutes.
Towing the Vehicle

vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash or
hook to suspension components.
Use the proper straps around the
tires to secure the vehicle. Do not
drag a locked wheel/tire while
loading the vehicle. Do not use a
sling type lift to tow the vehicle.
This could damage the vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach angles,
if necessary. A towed vehicle should
have its drive wheels off the ground.
Contact Roadside Service or a
professional towing service if the
disabled vehicle must be towed.
If the vehicle is equipped with a tow
eye, it is located in the trunk next to
the spare tire tools. Only use the tow
eye to pull the vehicle onto a flatbed car carrier from a flat road surface. Do
not use the tow eye to pull the vehicle
from snow, mud, or sand.Caution
Improper use of the tow eye can
cause vehicle damage. Use caution
and low speeds to prevent damage
to the vehicle.
Front Attachment Point
Carefully open the cover in the fascia
by using the small notch that conceals
the tow eye socket.
