wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the rear wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
Magnetic Ride Control™
With this feature on the CTS-V, the Magnetic Ride
Control system adjusts the ride of the vehicle to Touring
or Sport modes. Magnetic Ride Control monitors the
suspension system to determine the proper system
response.
TOUR:Use for normal city and highway driving.
This setting provides a smooth, soft ride.
SPORT:Use where road conditions or personal
preference demand more control. This setting provides
more “feel”, or response to road conditions.
The setting can be changed at any time. Based on road
conditions, steering wheel angle and the vehicle speed,
the system automatically adjusts to provide the best
handling while providing a smooth ride. The Touring and
Sport modes will feel similar on a smooth road. Select a
new setting whenever driving conditions change.
The Driver Information Center (DIC) briey displays
SUSPENSION MODE TOURING or SUSPENSION
MODE SPORT on vehicle startup or when a new mode
is selected.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep the vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes 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. Shift down to let the engine
assist the brakes on a steep downhill slope.
{CAUTION:
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.

Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. Turn off any traction or stability
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, seeTowing Your
Vehicle on page 4-26.
Loading the Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all
occupants, cargo, and all nonfactory-installed
options. Two labels on your vehicle show how much
weight it may properly carry, the Tire and Loading
Information label, and the Certication label.
{CAUTION:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.

Dolly Towing (Rear-Wheel-Drive
Vehicles)
Use the following procedure to dolly tow a
rear-wheel-drive vehicle from the rear:
1. Attach the dolly to the tow vehicle following the
dolly manufacturer’s instructions.
2. Put the rear wheels on the dolly.
3. Firmly set the parking brake. SeeParking Brake on
page 2-42.4. Put the vehicle in P (Park) for an automatic
transmission or in 1 (First) for a manual
transmission.
5. Securely attach the vehicle being towed to
the dolly.
6. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for towing.
7. Turn the ignition to LOCK/OFF.
Dolly Towing (All-Wheel-Drive Vehicles)
Notice:Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle
with any of its wheels on the ground.
All-wheel-drive vehicles can only be towed with all four
wheels on a trailer.
Towing a Trailer (CTS-V)
The CTS-V is neither designed nor intended to tow a
trailer.
4-27

Towing a Trailer (CTS)
{CAUTION:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well — or
even at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer/retailer for advice and information
about towing a trailer with the vehicle.The vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment.
To identify the trailering capacity of the vehicle, read the
information in “Weight of the Trailer” that appears
later in this section.
Trailering is different than just driving the vehicle by itself.
Trailering means changes in handling, acceleration,
braking, durability and fuel economy. Successful, safe
trailering takes correct equipment, and it has to be used
properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of these
are important for your safety and that of your passengers.
So please read this section carefully before pulling a
trailer.
Load-pulling components such as the engine,
transmission, rear axle, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. The trailer also adds considerably to wind
resistance, increasing the pulling requirements.
4-28

Pulling A Trailer
Here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
the rig will be legal, not only where you live but
also where you will be driving. A good source for
this information can be state or provincial police.
Do not tow a trailer at all during the rst 1,000 miles
(1 600 km) the new vehicle is driven. The engine,
axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
Vehicles with automatic transmissions can tow in
D (Drive). 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.
Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h), to
save wear on the vehicle’s parts.Three important considerations have to do with weight:
The weight of the trailer.
The weight of the trailer tongue.
The total weight on the vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (450 kg).
But even that can be too heavy.
It depends on how the rig is used. For example, speed,
altitude, road grades, outside temperature and how
much the vehicle is used to pull a trailer are all
important. It can depend on any special equipment on
the vehicle, and the amount of tongue weight the vehicle
can carry. See “Weight of the Trailer Tongue” later in
this section for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
Ask your dealer/retailer for our trailering information
or advice, or write us at our Customer Assistance
Offices. SeeCustomer Assistance Offices on page 7-6
for more information.
