Cadillac XT4 Owner's Manual page 188

StabiliTrak/ESC selectively applies
braking pressure at any one of the
vehicle's brakes to help steer the
vehicle in the direction in which you
are steering.
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. TCS and StabiliTrak/
ESC will automatically turn on when
cruise control is set.
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 If the
Vehicle Is Stuck 0 159 and Turning
the Systems Off and On later in this
section.
The indicator light for both systems is
in the instrument cluster. This
light will:
Flash when TCS is limiting
wheel spin.
Flash when StabiliTrak/ESC is
activated.
Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message may display in the
Driver Information Centre (DIC), and
comes on and stays on to indicate
that the system is inactive and is not
assisting the driver in maintaining
control. The vehicle is safe to drive,
but driving should be adjusted
accordingly.
If comes on and stays on:
1. Stop the vehicle.
DRIVING AND OPERATING
2. Turn the engine off and wait
15 seconds.
3. Start the engine.
Drive the vehicle. If comes on and
stays on, the vehicle may need more
time to diagnose the problem. If the
condition persists, see your dealer.
Turning the Systems Off and On
Caution
Do not repeatedly brake or
accelerate heavily when TCS is off.
The vehicle driveline could be
damaged.
