228 SAFETY
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution
when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
When TSC is functioning, the “ESC Activation/Malfunction
Indicat
or 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.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full br
aking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
m
onitor
ing how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet cond
itions. It will periodically 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 Rain Brake Support is active, there is
no notification to the driver and no driver interaction is
required.
Hill Descent Control (HDC) — If Equipped
HDC is
intended for low speed off road driving while in
4WD Low
Range. HDC maintains vehicle speed while
descending hills during various driving situations. HDC
controls vehicle speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not activate).
2. Enab
led (feature is enabled and ready but activation
condit
ions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle
speed)
.
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.
