Driving and Operating 9-9
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Top of hills: Be
alert—something could
be in your lane (stalled car,
accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction. Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑32improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control, if equipped,
on slippery surfaces.

Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Service
on page 13‑7. To get help
and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in the
Index.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (Carbon
Monoxide) gas to get inside. CO
could overcome you and kill you.
You cannot see it or smell it, so
you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you

Black plate (11,1)Cadillac CTS/CTS-V Owner Manual - 2011
Driving and Operating 9-11
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph) as
shown on the speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑89.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels as
little as possible. To prevent transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see
Towing the Vehicle
on
page 10‑117.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory‐installed options.

New Vehicle Break-In
Follow these recommended
guidelines during the first
2 414 km (1,500 miles) of driving
this vehicle. Parts have a break-in
period and performance will be
better in the long run.
For the first 2 414 km (1,500 miles):
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4,000
engine rpm.
.Avoid driving at any one
constant speed, fast or slow.
.Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
.Do not let the engine labor.
Never lug the engine in high
gear at low speeds. With amanual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
.Do not participate in track
events, sport driving schools,
or similar activities during this
break–in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 miles).
.To break in new tires, drive at
moderate speeds and avoid
hard cornering for the first
322 km (200 miles). New tires do
not have maximum traction and
may tend to slip.
.New brake linings also need a
break–in period. Avoid making
hard stops during the first
322 km (200 miles). This is
recommended every time brake
linings are replaced.
Ignition Positions
(Key Access)
The ignition switch can be turned to
four different positions.
To shift out of P (Park), the ignition
switch must be in ON/RUN or ACC/
ACCESSORY and the brake pedal
must be applied.
Notice:
Using a tool to force the
key from its cylinder could cause
damage or break the key. Use the
correct key and turn the key only
with your hand. Make sure the
key is all the way in. If it is and

This is the only position in which the
key can be removed. This position
locks the ignition and shifter on
automatic transmission vehicles,
and the ignition and steering wheel
on manual transmission vehicles.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags. In an emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition to LOCK/OFF.
4. Set the parking brake. See Parking Brake (Manual)

turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service.
B (ACC/ACCESSORY):
This
position lets you use things like the
radio and the windshield wipers
when the engine is off. This position
allows you to turn off the engine.
C (ON/RUN): This position is for
driving. It is the position the ignition
switch returns to after the engine
starts, and the key is released.
To shift the transmission out of
P (Park), the ignition key has to be
in ACC/ACCESSORY or ON/RUN.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not start if the
battery is allowed to drain for an
extended period of time.

the doors and turn the key to ON/
RUN and then back to LOCK/OFF.
Starting the Engine
Place the transmission in the
proper gear.
If the vehicle has the keyless
access system, the keyless access
transmitter must be authenticated in
order for the ignition control knob to
turn. The transmitter can be
authenticated either by putting your
foot on the brake pedal or by
pushing the ignition control knob in.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already

pedal and turn the ignition control
knob to the START position. If the
ignition control knob does not turn,
try pushing the knob in and turning
again. When the engine begins
cranking, let go of the ignition
control knob, it will return to the ON/
RUN position.
If the transmitter is not in the vehicle
or something is interfering with the
transmitter, the Driver Information
Center (DIC) will display
ELECTRONIC KEY NOT
DETECTED. SeeDriver Information
Center (DIC)
on page 5‑27for
more information.
If the battery in the keyless access
transmitter needs replacing, the DIC
displays REPLACE BATTERY IN
REMOTE KEY. The vehicle can
still be driven. See “Battery
Replacement” underRemote
Keyless Entry (RKE) System
Operation (Key Access)
on
page 2‑5or Remote Keyless Entry
(RKE) System Operation (Keyless
Access)
on page 2‑7for more
information. Notice:
Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Manual Transmission
The shift lever should be in neutral
position and the parking brake
engaged. Hold the clutch pedal
down to the floor and start the
engine. The vehicle will not start if
the clutch pedal is not all the
way down.
Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition key to
START. If the vehicle has the
keyless access system, push the
ignition control knob in and
rotate the knob to the START
position. When the engine starts,
let go of the ignition. The idle
speed will go down as your
engine gets warm. Do not race
the engine immediately after
starting it. Operate the engine and transmission gently to allow
the oil to warm up and lubricate
all moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START for many seconds,
cranking will be stopped after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also
prevents cranking if the engine
is already running. Engine
cranking can be stopped by
turning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.

Black plate (21,1)Cadillac CTS/CTS-V Owner Manual - 2011
Driving and Operating 9-21
When first starting the vehicle,
the engine idle speed will be
elevated to allow the catalytic
converter, an emissions control
device, to quickly reach
operating temperature. After
approximately 20 seconds, the
engine will begin to transition to
it's normal, quieter idle speed,
which can vary depending on
the temperature. This is normal
operation.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after 5‐10 seconds, especially in
very cold weather (below 0°F
or−18°C), it could be flooded
with too much gasoline. Try
pushing the accelerator pedal all
the way to the floor and holding it there as you hold the key in
START for up to a maximum of
15 seconds. Wait at least
15 seconds between each try, to
allow the cranking motor to cool
down. When the engine starts,
let go of the key and accelerator.
If the vehicle starts briefly but
then stops again, do the same
thing. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates.
Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Engine Coolant Heater
Vehicles with the engine coolant
heater can use this option
in cold weather conditions at or
below −18°C (0°F) for easier
starting and better fuel economy
during engine warm-up. Plug in the
coolant heater at least four hours
before starting your vehicle. An
internal thermostat in the plug-end
of the cord may exist which will
prevent engine coolant heater
operation at temperatures
above −18°C (0°F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located near the driver side strut
tower.
Remove the plastic cap to
access the plug.

3. Plug it into a normal, grounded110-volt AC outlet.
{WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
If you do not, it could be
damaged.
Contact your dealer for information
on how long to use the heater in
your particular area.
Shifting Into Park
{WARNING
It can be 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. 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, use the steps
that follow. If you are pulling a
trailer, see Driving Characteristics
and Towing Tips on page 9‑52.
Use this procedure to shift into
P (Park):
1. Hold the brake pedal down and set the parking brake.
See Parking Brake (Manual)
on
page 9‑33or Parking Brake
(Electric)on page 9‑34for more
information. 2. Move the shift lever into P (Park)
by holding in the button on the
shift lever and pushing the lever
all the way toward the front of
the vehicle.
3. Turn the ignition to LOCK/OFF.
4. For vehicles with key access, remove the key and take it with
you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
For vehicles with the keyless
access system, take the keyless
access transmitter with you.
