Jeep Grand Cherokee 2013 Operating Information Manual page 51

A quantity of non-toxic gas is generated to
inflate the side curtain air bag. The inflating side
curtain air bag pushes the outside edge of the
headliner out of the way and covers the window.
The air bag inflates in about 30 milliseconds
(about one-quarter of the time that it takes to
blink your eyes) with enough force to injure you
if you are not belted and seated properly, or if
items are positioned in the area where the side
curtain air bag inflates. This especially applies
to children. The side curtain air bag is only
about 3-1/2 in (9 cm) thick when it is inflated.
Because air bag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an air bag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC air bags may deploy on both
sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag
deployment, if the communication network re-
mains intact, and the power remains intact,
depending on the nature of the event the ORC
will determine whether to have the Enhanced
Accident Response System perform the follow-
ing functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has
power or until the ignition key is turned off.
• Turn on the interior lights, which remain on as
long as the battery has power or until the
ignition key is removed.
• Unlock the doors automatically.
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from IGN ON to
IGN OFF.
If A Deployment Occurs
The Advanced Front Air Bags are designed to
deflate immediately after deployment.
NOTE:
In a rollover the pretensioners and/or SAB
and SABIC - if equipped air bags may deploy
on both sides of the vehicle.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
• The nylon air bag material may sometimes
cause abrasions and/or skin reddening to the
driver and front passenger as the air bags
deploy and unfold. The abrasions are similar
to friction rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chemi-
cals. They are not permanent and normally
heal quickly. However, if you haven't healed
significantly within a few days, or if you have
any blistering, see your doctor immediately.
