246 SAFETY
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions Ú page 189.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM)
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.
Rear Detection Zones
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 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. 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 (greater
then 15 mph) 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 random false detections on the
trailer, and false chimes when the turn signal
is used Ú page 207.
The BSM system may experience dropouts
(blinking on and off) of the side mirror
Warning Indicator lamps when a motorcycle
or any small object remains at the side of the
vehicle for extended periods of time (more
than a couple of seconds).
The area on the rear fascia/bumper 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/bumper where
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer
sway.
