2012 JEEP GRAND CHEROKEE sensor

A quantity of non-toxic gas is generated to inflate the
SABIC. The inflating SABIC pushes the outside edge of
the headliner out of the way and covers the window. The
SABIC 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 SABIC inflates. This especially applies to
children. The SABIC 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, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains 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.

Lift the cover to reveal the mirror. The light will turn on
automatically.
Sun Visor Extension — If Equipped
This feature has a pull out extension on the sun visor for
increased coverage.
BLIND SPOT MONITORING — IF EQUIPPED
The Blind Spot Monitoring (BSM) system uses two radar-
based sensors, located inside the rear bumper fascia, to
detect highway licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.

Rear Detection Zones
112 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear or REVERSE and enters stand by mode
when the vehicle is in PARK.
The BSM detection zone covers approximately one lane
on both sides of the vehicle (11 ft or 3.35 m). The zone
starts at the outside rear view mirror and extends ap-
proximately 20 ft (6 m) to the rear of the vehicle. The BSM
system monitors the detection zones on both sides of the
vehicle when the vehicle speed has reached approxi-
mately 6 mph (10 km/h) or higher and will alert the
driver of vehicles in these areas.NOTE:
•The BSM system does NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones.
•The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually
verify the adjacent lane is clear for both your vehicle
and trailer before making a lane change. If the trailer
or other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in the
BSM warning light remaining illuminated the entire
time the vehicle is in a forward gear.3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 113

The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function
properly. Do not block the area of the rear fascia where
the radar sensors are located with foreign objects (bum-
per stickers, bicycle racks, etc.).The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning light
located in the outside mirrors in addition to sounding an
audible (chime) alert and reducing the radio volume.
Refer to “Modes Of Operation” for further information.

RCP monitors the rear detection zones on both sides of
the vehicle, for objects that are moving toward the side of
the vehicle with a minimum speed of approximately 1 to
2 mph (1 km/h to 3 km/h), to objects moving a maxi-
mum of approximately 10 mph (16 km/h), such as in
parking lot situations.NOTE:
In a parking lot situation, oncoming vehicles can
be obscured by vehicles parked on either side. If the
sensors are blocked by other structures or vehicles, the
system will not be able to alert the driver.
When RCP is on and the vehicle is in REVERSE, the
driver is alerted using both the visual and audible
alarms, including reducing the radio volume.
WARNING!
RCP is not a Back Up Aid system. It is intended to be
used to help a driver detect an oncoming vehicle in a
parking lot situation. Drivers must be careful when
backing up, even when using RCP. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before back-
ing up. Failure to do so can result in serious injury or
death.

ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor designed to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.
WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the vehicle
ahead; and, most importantly, brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.(Continued)

To change the distance setting, press the Distance button
and release. Each time the button is pressed, the distance
setting adjusts between long, medium, and short.If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically to maintain the distance setting, regardless of
the set speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
•The vehicle ahead moves out of your lane or view of
the sensor.
•The vehicle ahead slows to a speed below 15 mph
(24 km/h) and the system automatically disengages
itself.
•The distance setting is changed.
