Driving and Operating
179
If the vehicle is on a steep grade, the brake
pedal must be used to hold the vehicle.
When available regenerative braking power
is limited, the hydraulic brakes may be
applied to make up the difference.
Cruise control will turn off and the brake
lamps may come on when this feature is
activated.
Avoid using Regen on Demand under
slippery road conditions. Use the brake
pedal as the primary braking device.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC). These systems help limit
wheel spin and assist the driver in
maintaining control, especially on slippery
road conditions.
TCS activates if it senses any of the drive
wheels are spinning or beginning to lose
traction. When this happens, TCS applies the
brakes to the spinning wheels and reduces
vehicle power to limit wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to one or more of the
vehicle wheel brakes to assist the driver in
keeping the vehicle on the intended path.
Trailer Sway Control (TSC) is also on
automatically when the vehicle is started.
See
If cruise control is being used and traction
control or StabiliTrak/ESC begins to limit
wheel spin, cruise control will disengage.
Cruise control may be turned back on when
road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
and
“
Turning the
Systems Off and On
”
later in this section.
The indicator light for both systems is in the
instrument cluster. This light:
.
Flashes when TCS is limiting wheel spin
.
Flashes when StabiliTrak/ESC is activated
.
Turns on and stay on when either system
is not working
See
Traction Control System (TCS)/StabiliTrak
.
If either system fails to turn on or to
activate, a message displays in the Driver
Information Center (DIC), and
d
comes on
and stays on to indicate that the system is
inactive and is not assisting the driver in
maintaining control. Adjust driving
accordingly.
