Auxiliary Driving Systems; Blind Spot Monitoring (Bsm) - Jeep GRAND CHEROKEE 2023 Owner's Manual

Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine power to be applied to the wheel that is
not spinning. BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in reduced modes.

AUXILIARY DRIVING SYSTEMS

B S M
LIND POT ONITORING
The BSM system uses two radar sensors, located inside
the rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.) that
enter the blind spot zones from the rear/front/side of the
vehicle.
When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
(BSM)
forward gear.
The BSM detection zone covers approximately one lane in
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the side of the vehicle, near the B-pillar,
and extends approximately 10 ft (3 m) beyond the rear
fascia/bumper of the vehicle.
Rear Detection Zones
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. BSM will alert earlier
on faster approaching vehicles — up to 33 mph (54 km/h)
difference.
NOTE:
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 random false detections
on the trailer, and false chimes when the turn signal is
used page 168.
Ú
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If blockage is detected,
a "Blind Spot Temporarily Unavailable, Sensor Blocked"
message will display in the cluster, both mirror lights will
illuminate, and BSM and RCP alerts will not occur. This is
normal operation.
