Competitive Driving
Competitive driving may affect the
vehicle warranty. See the warranty
book before using the vehicle for
competitive driving.
Notice:If you use your vehicle
for competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine. Be
sure to check the oil level often
during competitive driving and
keep the level at or near the
upper mark that shows the proper
operating range on the engine oil
dipstick. For information on how
to add oil, see Engine Oil
on
page 10‑11.
CTS‐V Only: For competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a
dry boiling point greater than 279°C
(534°F). After conversion to the high
performance brake fluid, follow the
brake fluid service recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT‐5 brake fluids.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
(Continued)
WARNING (Continued)
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.

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

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.

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.

unleaded gasoline with an octane
rating of 87 or higher. If 87 octane
fuel is used, do not perform any
aggressive driving maneuvers such
as wide open throttle applications.
You might also hear audible spark
knock during acceleration. Refill the
tank with premium fuel as soon as
possible to avoid damaging the
engine. If heavy knocking is heard
when using gasoline rated at
91octane or higher, the engine
needs service.
Gasoline Specifications
At a minimum, gasoline
should meet ASTM specification D
4814 in the United States or CAN/
CGSB‐3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 9‑49for additional
information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See Malfunction Indicator Lamp
on
page 5‑19. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States or
Canada, the proper fuel might be
hard to find. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused by
use of improper fuel would not be
covered by the vehicle warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.

Fuel Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing the
emission control system to work
properly. In most cases, nothing
should have to be added to the fuel.
However, some gasolines contain
only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean,
or if the vehicle experiences
problems due to dirty injectors or
valves, look for gasoline that is
advertised as TOP TIER Detergent
Gasoline. Look for the TOP TIER
label on the fuel pump to ensure
gasoline meets enhanced
detergency standards developed by
the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change, can
help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
the life of spark plugs and the
performance of the emission control
system could be affected. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.

9-54 Driving and Operating
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, move that hand
to the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won't strike soft shoulders, curbs, road signs, trees
or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes, or stopping.
When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to
be sure the trailer bulbs are still
working.
Driving On Grades
Reduce speed and shift to a
lower gear before starting down a
long or steep downgrade. If the
transmission is not shifted down, thebrakes might have to be used so
much that they would get hot and no
longer work well.
Vehicles with an automatic
transmission can tow in D (Drive)
but M (Manual Mode) is
recommended. Shift the
transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
For vehicles with a manual
transmission, it is better not to use
the highest gear.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run

Black plate (55,1)Cadillac CTS/CTS-V Owner Manual - 2011
Driving and Operating 9-55
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, seeEngine Overheating
on page 10‑24.
Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet for
vehicles with an automatic
transmission, or into gear for
vehicles with a manual transmission. Turn the wheels
into the curb if facing downhill or
into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park) for vehicles with an
automatic transmission or into
gear for vehicles with a manual
transmission.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.Start the engine,
.Shift into a gear, and
.Release the parking brake.
2. Let up on the brake pedal. 3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual's Maintenance Schedule or
Index for more information. Things
that are especially important in
trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system, and
brake system. It is a good idea to
inspect these before and during
the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
