9-26 Driving and Operating
N (Neutral):In this position, the
engine does not connect with the
wheels. To restart when the vehicle
is already moving, use N (Neutral)
only. You can also use N (Neutral)
when the vehicle is being towed.
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle. D (Drive):
This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, and you are:
.Going less than 55 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 55 km/h (35 mph) or
more, push the accelerator all
the way down.
The transmission will shift down
to a lower gear and have more
power.
Downshifting the transmission in
slippery road conditions could result
in skidding; see “Skidding”under
Loss of Control on page 9‑5.
Notice: Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. If you are stuck,
do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Manual Mode
Driver Shift Control (DSC)
Notice: 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.

Black plate (28,1)Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
9-28 Driving and Operating
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.
SeeTransmission Messages on
page 5‑42.
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 on page 9‑37.Manual Transmission
If the vehicle has a manual
transmission, the shift lever is
located on the center console
between the front seats.
1 (First): Press the clutch pedal
and shift into 1 (First). Slowly let up
on the clutch pedal while pressing
on the accelerator pedal.
After a complete stop, if it is hard to
shift into 1 (First), let up on the
clutch pedal, then press it back
down and shift into 1 (First). 2 (Second):
Press the clutch pedal
and let up on the accelerator pedal,
then shift into 2 (Second). Then,
slowly let up on the clutch pedal
while accelerating.
3 (Third), 4 (Fourth), 5 (Fifth), and
6 (Sixth): Shift into 3 (Third),
4 (Fourth), 5 (Fifth), and 6 (Sixth) the
same as 2 (Second).
To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral.
Neutral: Use this position when
you start or idle the engine. The
shift lever is in Neutral when it is
centered in the shift pattern, not in
any gear.
R (Reverse): To back up, press
down the clutch pedal, completely
stop the vehicle, and shift into
R (Reverse). Let up on the clutch
pedal slowly while pressing the
accelerator pedal.

Driving and Operating 9-29
{WARNING
If you skip a gear when you
downshift, you could lose control
of the vehicle. You could injure
yourself or others. Do not shift
down more than one gear at a
time when you downshift.
Notice: If you skip more than one
gear when you downshift, or if
you race the engine when you
release the clutch pedal while
downshifting, you could damage
the engine, clutch, driveshaft or
the transmission. Do not skip
gears or race the engine when
downshifting.
Drive Systems
All-Wheel Drive
Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5‑20.

Black plate (30,1)Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
9-30 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake (Electric)
Automatic Transmission
Manual Transmission

Black plate (31,1)Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
Driving and Operating 9-31
The vehicle may have an Electric
Parking Brake (EPB). The switch
for the EPB is on the center console
for vehicles with a manual
transmission, or on the left side of
the instrument panel for vehicles
with an automatic transmission. The
EPB can always be activated, even
if the ignition is off. To prevent
draining the battery, avoid repeated
cycles of the EPB system when the
engine is not running.
The system has a parking brake
status light and a parking brake
warning light. SeeParking Brake
Light on page 5‑19 andService
Electric Parking Brake Light on
page 5‑19. There are also parking
brake related Driver Information
Center (DIC) messages. See Brake
System Messages on page 5‑33. In
case of insufficient electrical power,
the EPB cannot be applied or
released.
Before leaving the vehicle, check
the parking brake status light to
ensure that the parking brake is
applied.EPB Apply
The EPB can be applied any time
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the EPB switch. Once fully applied,
the parking brake status light will be
on. While the brake is being applied,
the status light will flash until it is
fully applied. If the light does not
come on, or remains flashing, you
need to have the vehicle serviced.
Do not drive the vehicle if the
parking brake status light is flashing.
See your dealer. See Parking Brake
Light on page 5‑19.
If the EPB is applied while the
vehicle is in motion, a chime will
sound, and a DIC message will be
displayed. The vehicle will
decelerate as long as the switch is
held in the up position. Releasing
the EPB switch during deceleration
will release the parking brake. If the
switch is held in the up position until
the vehicle comes to a stop, the
EPB will remain applied. If the parking brake status light
flashes continuously, then the EPB
is only partially applied or released,
or there is a problem with the EPB.
A DIC message will be displayed.
If this light flashes continuously,
release the EPB, and attempt to
apply it again. If this light continues
to flash, do not drive the vehicle.
See your dealer.
If the parking brake warning light is
on, the EPB has detected an
internal error, or a fault in another
system, and is operating with
reduced functionality. To apply the
EPB when this light is on, lift up on
the EPB switch and hold it in the up
position. Full application of the
parking brake by the EPB system
may take a longer period of time
than normal when this light is on.
Continue to hold the switch until the
parking brake status light remains
on. If the parking brake warning light
is on, see your dealer.

Black plate (32,1)Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
9-32 Driving and Operating
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB, place the
ignition in the ACC/ACCESSORY or
ON/RUN position, apply and hold
the brake pedal, and push down
momentarily on the EPB switch.
If you attempt to release the EPB
without the brake pedal applied, a
chime will sound, and a DIC
message will be displayed. The
EPB is released when the parking
brake status light is off.If the parking brake warning light is
on, the EPB has detected an error
in another system and is operating
with reduced functionality. To
release the EPB when this light is
on, push down on the EPB switch
and hold it in the down position.
EPB release may take a longer
period of time than normal when this
light is on. Continue to hold the
switch until the parking brake status
light is off. If the light is on, see your
dealer.
Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
The EPB can also be used to
prevent roll back for vehicles with
a manual transmission taking off on
a hill. In a situation where no roll
back is desired, an applied EPB will
allow both feet to be used for the
clutch and accelerator pedals in
preparation for starting the vehicle
moving in the intended direction.
In this situation, perform the normal
clutch and/or accelerator actions
required to begin moving the
vehicle. There is no need to push
the switch to release the EPB.
If parking on a hill, or if the vehicle
is pulling a trailer, see Driving
Characteristics and Towing Tips on
page 9‑70.

when you begin to drive, the brake
system warning light will be on and
a chime will sound warning you that
the parking brake is still on.
If you are towing a trailer and are
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑70.
Brake Assist
This vehicle has a brake assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal
as the driving situation dictates.
The brake assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.

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
dflashes 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
dcomes on and stays on, the
vehicle is safe to drive but the
system is not operational. Driving
should be adjusted accordingly.

9-36 Driving and Operating
StabiliTrak®System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak activates when the
computer senses a difference
between the intended path, and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to help steer
the vehicle in the intended direction.
StabiliTrak is on automatically
whenever the vehicle is started. To
assist with directional control of the
vehicle, the system should always
be left on.
TCS/StabiliTrak Light
When the stability control system
activates,
dflashes on the
instrument cluster. This also occurs
when traction control is activated.
A noise may be heard or vibration
may be felt in the brake pedal. This
is normal. Continue to steer the
vehicle in the intended direction.
If there is a problem detected with
StabiliTrak, a message is displayed
on the Driver Information Center
(DIC). See Ride Control System
Messages on page 5‑40. When one of these messages is
displayed and/or
dcomes on and
stays on, the vehicle is safe to drive
but the system is not operational.
Driving should be adjusted
accordingly.
If
dcomes on and stays on, reset
the system:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
