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 park 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 you are towing a trailer and
parking on a hill, seeDriving
Characteristics and Towing Tips on
page 9‑51 for more information.
Brake Assist
(Except CTS-V)
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.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that 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 (AWD) 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.

WARNING (Continued)
.Fuel can spray out if the fuel
cap is opened too quickly.
This spray can happen if the
tank is nearly full, and is
more likely in hot weather.
Open the fuel cap slowly and
wait for any hiss noise to stop
then unscrew the cap all
the way
The cap is behind a locking fuel
door on the passenger side of the
vehicle.
To open the fuel door, push the
rearward center edge in and release
and it will open.
To remove the tethered fuel cap,
turn it slowly counterclockwise.
While refueling, hang the tethered
fuel cap from the hook on the
fuel door.
If the fuel cap is not installed
properly, a message will appear on
the Driver Information Center
display. SeeFuel System Messages
on page 5‑36.
When reinstalling the cap, turn it
clockwise until it clicks once,
otherwise the malfunction indicator
lamp could turn on. See Malfunction
Indicator Lamp on page 5‑19. Be careful not to spill fuel. Do not
top off or overfill the tank and wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑105.
When replacing the fuel cap, turn it
clockwise until it clicks once. Make
sure the cap is fully installed. The
diagnostic system can determine if
the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. See
Malfunction
Indicator Lamp on page 5‑19.
{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.

Driving and Operating 9-53
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your 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 so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster 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 cluster flash for turns
even if the bulbs on the trailer are
burned out. 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 thetransmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils 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 could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10‑21.

9-54 Driving and Operating
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. 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.
.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 the
Maintenance Schedule on
page 11‑3. Things that are
especially important in trailer
operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
on page 10‑21.
Trailer Towing (CTS-V and
Coupe)
The vehicle is neither designed nor
intended to tow a trailer.

4. Install the air cleaner housingcover screws.
5. Install the hose to the air cleaner housing mounting arm. The hose
must be routed correctly.
6. Install the air cleaner outlet duct to the air cleaner housing.
7. Tighten the air cleaner outlet duct screw clamp.
8. Attach the electrical connector to the air box.
9. Reinstall the side cover.
{WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off. Notice:
If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.

{WARNING
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.

Vehicle Care 10-19
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant surge tank.
If no coolant is visible in the surge
tank, add coolant as follows:
1. Remove the coolant surge tankpressure cap when the cooling
system, including the coolant
surge tank pressure cap and
upper radiator hose, is no longer
hot. Turn the pressure cap
slowly counterclockwise about
one-quarter turn and then stop.
If you hear a hiss, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure capslowly and remove it.
3. Fill the coolant surge tank withthe proper mixture, to slightly
above the FROID/FULL COLD
line on the side of the coolant
surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. The upper radiator
hose is the top hose coming out
of the radiator, on the passenger
side of the vehicle. Watch out for
the engine cooling fans.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge tank
until the level reaches the
FROID/FULL COLD line on the
side of the coolant surge tank.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.

10-20 Vehicle Care
Notice:If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Recheck the coolant level in the
bottle next time you use your
vehicle to ensure the system is full
when cold.
Checking Coolant in the
Intercooler System (CTS-V)
The vehicle must be on a level
surface when checking the coolant
level.
The super charged engine
intercooler coolant fill neck is in the
engine compartment on the
passenger side of the vehicle. See
Engine Compartment Overview on
page 10‑5.
On the coolant fill neck, there is a
cold fill region between the two
horizontal lines shown.
Check to see if coolant is visible in
the coolant fill neck. If the coolant is
not visible or below the cold fill region in the fill neck, add a 50/
50 mixture of clean, drinkable water
and DEX-COOL coolant at the
coolant fill bottle, but be sure the
cooling system is cool before this
is done.
Adding Coolant to the
Intercooler System
Coolant (CTS-V)
1. Remove the intercooler system
pressure cap when the
intercooler system hoses are no
longer hot. Turn the pressure
cap slowly counterclockwise about one-quarter of a turn.
If you hear a hiss, wait for that to
stop. This allows any pressure
still left to be vented.
2. Keep turning the pressure cap slowly and remove it.
3. Add the proper DEX-COOL coolant mixture to the fill neck
until the coolant is within the
cold fill region.
With the intercooler system
pressure cap off, start the
engine and let it run for a couple
of minutes. Then turn the engine
off. By this time, the coolant
level inside the fill neck may be
lower. If the level drops where
coolant is no longer within the
cold fill region of the fill neck
with the engine off, add more of
the DEX-COOL coolant mixture
to the fill neck until the level is
again visible in the cold fill
region.
4. Replace the pressure cap tightly.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
