152 SAFETY
Rain Brake Support (RBS)
Rain Brake Support (RBS) may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure to
remove any water buildup on the front brake
rotors. It functions when the windshield wipers
are in LO or HI speed. When RBS is active, there
is no notification to the driver and no driver
interaction is required.
Trailer Sway Control (TSC)
Trailer Sway Control (TSC) uses sensors in the
vehicle to recognize an excessively swaying
trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become
active automatically once an excessively
swaying trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting And
Operating” for further information.
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” or “Full Off” modes.
Traction Control System (TCS)
The Traction Control System (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 similar 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 torque to be applied to the wheel that is
not spinning. BLD may remain enabled even if
TCS and Electronic Stability Control (ESC) are in
a reduced mode.
AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses
two radar-based sensors, located inside the tail-
lights, 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
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 (R) and enters standby mode when
the vehicle is in PARK (P).
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.
