2015 JEEP GRAND CHEROKEE warning light

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
width on both sides of the vehicle (12 ft or 3.8 m). The
zone length starts at the outside rear view mirror and
extends approximately 10 ft (3 m) beyond the rear
bumper of the vehicle. The BSM system monitors the
detection zones on both sides of the vehicle when the
vehicle speed reaches approximately 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 de-
tection 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.
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.
Sensor Location
136 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to
see if an alert is necessary. The BSM system will issue an
alert during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from either
side of the vehicle.

Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection zone with a relative
speed of less than 30 mph (48 km/h).
Overtaking Traffic
If you pass another vehicle slowly (with a relative speed
less than 10 mph (16 km/h) and the vehicle remains in
the blind spot for approximately 1.5 seconds, the warning
light will be illuminated. If the difference in speed
between the two vehicles is greater than 10 mph
(16 km/h), the warning light will not illuminate.

CAUTION!
To prevent possible damage, do not slam the hood to
close it. Use a firm downward push at the front center
of the hood to ensure that both latches engage.
WARNING!
Be sure the hood is fully latched before driving your
vehicle. If the hood is not fully latched, it could open
when the vehicle is in motion and block your vision.
Failure to follow this warning could result in serious
injury or death.
LIGHTS
Headlight Switch
The headlight switch is located on the left side of the
instrument panel, next to the steering wheel. The head-
light switch controls the operation of the headlights,
parking lights, instrument panel lights, cargo lights and
fog lights (if equipped).

WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
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 and a forward facing camera 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.

•The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the DID and a chime will sound
while ACC continues to apply its maximum braking
capacity.NOTE:The “Brake!” Screen in the DID is a warning for
the driver to take action and does not necessarily mean
that the Forward Collision Warning system is applying
the brakes autonomously.

WARNING!
In the normal Cruise Control mode, the system will
not react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound
even if you are too close to the vehicle ahead since
neither the presence of the vehicle ahead nor the
vehicle-to vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and
the vehicle ahead. Always be aware which mode is
selected.
To Set A Desired Speed
Turn the Normal (Fixed Speed) Electronic
Speed Control ON. When the vehicle has
reached the desired speed, press the SET (+) or
SET (-) button and release. Release the accel-
erator and the vehicle will operate at the selected speed.
Once a speed has been set a message (CRUISE CON-
TROL SET TO MPH/KM) will appear indicating what
speed was set. This light will turn on when the electronic
speed control is SET.
To Vary The Speed Setting
To Increase Speed
When the Normal (Fixed Speed) Electronic Speed Con-
trol is set, you can increase speed by pressing the SET+
button.
The speed increment shown is dependant on the speed of
U.S. (mph) or Metric (km/h) units:
U.S. Speed (mph)
•Pressing the SET+button once will result ina1mph
increase in set speed. Each subsequent tap of the
button results in an increase of 1 mph.
