Ready Alert Braking (RAB)
Ready Alert Braking (RAB) may reduce the time required to
reach full braking during emergency braking situations. It
anticipates when an emergency braking situation may occur
by monitoring 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 (RBS) may improve braking perfor-
mance in wet conditions. 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 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 recommendations. 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.
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.
