2016 JEEP GRAND CHEROKEE trailer

The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (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.).

WARNING!(Continued)
brakes must be applied manually. An audible
chime will sound when the brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow, sleet,
heavy traffic, and complex driving situations (i.e.,
in highway construction zones).
• When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy, snow-
covered, slippery, or have steep uphill or downhill
slopes.
• When towing a trailer up or down steep slopes.
• When circumstances do not allow safe driving at a
constant speed.

memory if:
•The Adaptive Cruise Control (ACC) ON/OFF button
is pushed.
• The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pushed. •
The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.

Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.
ParkSense System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense system operating
properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn ParkSense OFF, the instrument cluster
will display “PARKSENSE OFF” Furthermore, once
you turn ParkSense off, it remains off until you turn it
on again, even if you cycle the ignition. •
When you move the gear selector to the REVERSE
position and ParkSense is turned OFF, the DID will
display “PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
• ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system
OFF if objects such as bicycle carriers, trailer hitches,
etc. are placed within 12 in (30 cm) from the rear
fascia/bumper. Failure to do so can result in the
