build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
• After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESP. This
system includes Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System (BAS), Hill
Start Assist (HSA), Electronic Roll Mitigation (ERM), and
Electronic Stability Program (ESP). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Two additional electronic brake control system options
are Hill Descent Control (HDC) and Trailer Sway Control
(TSC). Your vehicle may be equipped with one or both of
these options.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up to
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.
