Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
9-34 Driving and Operating
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After the driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the two-second
window. It will not activate if the
vehicle is in a drive gear and facing
downhill, or if the vehicle is facing
uphill and in R (Reverse).
Ride Control Systems
Traction Control
System (TCS)
The vehicle has TCS, which limits
wheel spin. This is especially useful
in slippery road conditions. On a
rear-wheel-drive vehicle, the system
operates if it senses that one or
both of the rear wheels are spinning
or beginning to lose traction. On an
all—wheel—drive vehicle, the
system will operate if it senses that
any of the wheels are spinning or
beginning to lose traction. When this
happens, the system brakes the
spinning wheel(s) and/or reduces
engine power to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
TCS is on whenever the vehicle
is started. To limit wheel spin,
especially in slippery road
conditions, the system should
always be left on. But, TCS can be
turned off if needed.
TCS/StabiliTrak Light
d flashes to indicate that the TCS is
active.
If there is a problem detected with
TCS, a message may be displayed
on the Driver Information Center
(DIC). See Ride Control System
Messages on page 5‑40. When
one of these messages is displayed
and
d comes on and stays on, the
vehicle is safe to drive but the
system is not operational. Driving
should be adjusted accordingly.
