DRIVING AND OPERATING 189
Leaving the Vehicle with the
Engine Running
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle can
move suddenly. You or others could
be injured. To be sure the vehicle
will not move, even when you are
on fairly level ground, always set
the parking brake and move the
shift lever to P (Park). SeeShifting
Into Park 0188.
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking brake
set. After shifting into P (Park), try to
move the shift lever without first
pushing the button on the shift lever.
If you can, the shift lever was not
fully locked into P (Park).
Torque Lock
Torque lock is when the weight of the
vehicle puts too much force on the
parking pawl in the transmission. This
happens when parking on a hill and
shifting the transmission into P (Park)
is not done properly and then it is
difficult to shift out of P (Park). To
prevent torque lock, set the parking
brake and then shift into P (Park). To
find out how, see "Shifting Into Park"
listed previously.
If torque lock does occur, the vehicle
may need to be pushed uphill by
another vehicle to relieve the parking
pawl pressure, so you can shift out of
P (Park).
Shifting out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to
prevent movement of the shift lever
out of P (Park), unless the ignition is
in ON/RUN/START and the brake
pedal is applied. The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See
Jump Starting 0292.
To shift out of P (Park):
1. Apply the brake pedal.
2. Turn the ignition to ON/RUN/ START.
3. Release the parking brake. See Parking Brake (Manual) 0195 or
Parking Brake (Electric) 0196.
4. Press the shift lever button.
5. Move the shift lever.
If unable to shift out of P (Park): 1. Fully release the shift lever button.

(Continued)
Caution (Continued)
do not spin the tires. When
stopping on a hill, use the brakes to
hold the vehicle in place.
While in Sport Mode, the vehicle
monitors driving behavior, and
automatically enables Performance
Shift Features when spirited driving is
detected. These features maintain
lower transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will
exit these features and return to
normal operation after a short period
when no spirited driving is detected.
See Driver Mode Control 0199.
Manual Mode
Driver Shift Control (DSC)
Caution
Driving with the engine at a high
rpm without upshifting while using
Driver Shift Control (DSC), could
damage the vehicle. Always upshift
when necessary while using DSC.
Vehicles with DSC may either use the
shift lever or the tap shift controls on
the back of the steering wheel (if
equipped) to manually shift the
automatic transmission.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -
2017 - crc - 6/16/16
194 DRIVING AND OPERATING
To use DSC using the shift lever:1. Move the shift lever to the left from D (Drive) to M (Manual
Mode). The transmission will be
in Manual Mode and will hold
the current gear.
2. Move the shift lever forward to upshift or rearward to downshift.
3. To cancel DSC, move the shift lever back to D (Drive).
Tap Shift
If equipped, the tap shift controls are
on the back of the steering wheel. To use DSC using the tap shift
controls:
1. Move the shift lever to the left from D (Drive) to M (Manual
Mode). The transmission will be
in Manual Mode and will hold
the current gear.
2. Pull the control toward you to shift. Pull the left control to
(−) downshift, and the right
control to (+) upshift.
3. To cancel DSC, move the shift lever back to D (Drive).
Tap Shift Mode can also be used
temporarily while driving in D (Drive).
Pull either the (+) upshift or
(−) downshift control.
To cancel Tap Shift Mode, hold
the (+) upshift control for two seconds.
If no action is taken, the vehicle
returns to automatic shifting after a
brief period of driving at a steady
speed, or when the vehicle comes to
a stop.
While using the DSC feature, the
vehicle will have firmer, quicker
shifting. This can be used for sport driving, climbing or descending hills,
staying in gear longer, downshifting
for more power, or engine braking.
The transmission will only allow
shifting into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). The transmission
will not automatically shift to the next
lower or higher gear if the engine rpm
is too high or too low.
If shifting is prevented for any reason,
a DIC message will appear. See
Transmission Messages
0136.
When accelerating the vehicle from a
stop in snowy and icy conditions, it is
suggested to shift into second gear.
A higher gear allows the vehicle to
gain more traction on slippery
surfaces. See Driver Mode
Control 0199.

sound warning you that the parking
brake is still on.
Parking Brake (Electric)
If equipped with an Electric Parking
Brake (EPB), the switch is on the left
side of the instrument panel. The EPB
can always be activated, even if the
ignition is off. To prevent draining the
battery, avoid repeated cycles of the
EPB when the engine is not running.
The system has a red parking brake
status light and an amber parking
brake warning light. See Parking Brake
Light 0116 and Service Electric Parking
Brake Light 0117. There are also
parking brake-related Driver
Information Center (DIC) messages. See
Brake System Messages 0128. In
case of insufficient electrical power,
the EPB cannot be applied or released.
Before leaving the vehicle, check the
red parking brake status light to
ensure that the parking brake is
applied.

To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Lift up the EPB switch momentarily.
The red parking brake status light will
flash and then stay on once the EPB is
fully applied. If the red parking brake
status light flashes continuously, then
the EPB is only partially applied or
there is a problem with the EPB.
A DIC message will display. Release
the EPB and try to apply it again.
If the light does not come one,
or keeps flashing, have the vehicle
serviced. Do not drive the vehicle if
the red parking brake status light is

198 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 sufficient enough to activate
HSA. 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
for a maximum of two seconds 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/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that 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 engine
power to limit wheel spin.
StabiliTrak activates when the vehicle
senses a difference between the
intended path and the direction the
vehicle is actually traveling.
StabiliTrak selectively applies braking
pressure to any one of the vehicle
wheel brakes to assist the driver in
keeping the vehicle on the
intended path. If cruise control is being used and
traction control or StabiliTrak 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
If the
Vehicle Is Stuck 0180 and “Turning
the Systems Off and On ”later in this
section.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -

DRIVING AND OPERATING 199
The indicator light for both systems is
in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak 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 displays in the
Driver Information Center (DIC), and
dcomes 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
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
4. Drive the vehicle. If
dcomes 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
Thegbutton for TCS and StabiliTrak
is on the center console (ATS) or the
steering wheel (ATS-V).
