268 Driving and Operating
Warning (Continued)
It is 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.
Do not leave the vehicle
when the engine is running.
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, always
set the parking brake and
move the shift lever to
P (Park). See Shifting Into
Park (Mechanical Shifter)
0267 or
Shifting Into Park (Electronic
Shifter) 0268. If you are
towing a trailer, see Driving
Characteristics and Towing
Tips 0358. If you have to leave the vehicle
with the engine running, be
sure the vehicle is in P (Park)
and the parking brake is set
before you leave it. After you
have moved the shift lever
into P (Park), hold the regular
brake pedal down. Then, see if
you can move the shift lever
away from P (Park) without
first pressing the button.
If you can, it means that the
shift lever was not fully locked
in P (Park).
Torque Lock
Torque lock is when the
weight of the vehicle puts too
much force on the parking
pawl in the transmission. This
happens when parking on a hill
and shifting the transmission
into P (Park) is not done
properly and then it is difficult
to shift out of P (Park). To
prevent torque lock, set the
parking brake and then shift
into P (Park). To find out how,
see
“Shifting Into Park” listed
previously. If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to
relieve the parking pawl
pressure, so you can shift out
of P (Park).
Shifting Into Park
(Electronic Shifter)
To shift into P (Park):
1. Hold the brake pedal down and set the parking brake.
See Electric Parking Brake
0287.
2. Press the button on top of the shift lever to shift into
P (Park). See Automatic
Transmission (Mechanical
Shifter) 0272 or
Automatic Transmission
(Electronic Shifter) 0275.
3. The P indicator on the shift lever will turn red when the
vehicle is in P (Park).
If the vehicle is shifted into
P (Park) on a hill, the
Electric Parking Brake
(EPB) may apply

Trailer Towing (LSY
2.0L L4 Engine)
Caution
Towing a trailer improperly
can damage the vehicle and
result in costly repairs not
covered by the vehicle
warranty. To tow a trailer
correctly, follow the
directions in this section and
see your dealer for
important information about
towing a trailer with the
vehicle.
Never tow a trailer with a
V-Series or V-Series
Blackwing. These models are
not designed or intended to
tow a trailer.
Trailer Weight
{Warning
Never exceed the towing
capacity for your vehicle.
Safe trailering requires
monitoring the weight, speed,
altitude, road grades, outside
temperature, dimensions of
the front of the trailer, and
how frequently the vehicle is
used to tow a trailer.
Before towing a trailer, always
separately weigh:
.the total weight on the
vehicle's tires.
.the trailer.
.the trailer tongue.
{Warning
You and others could be
seriously injured or killed if
the trailer is too heavy or
the trailer brakes are
inadequate for the load. The
vehicle may be damaged,
and the repairs would not be
covered by the vehicle
warranty.
Only tow a trailer if all the
steps in this section have
been followed. Ask your
dealer for advice and
information about towing a
trailer.

364 Driving and Operating
Gross Vehicle Weight
Rating (GVWR)
For information about the
vehicle's maximum load
capacity, see Vehicle Load
Limits0255. When calculating
the GVWR with a trailer
attached, the trailer tongue
weight must be included as
part of the weight the vehicle
is carrying.
Maximum Trailer Weight
The trailer should never weigh
more than 454 kg (1,000 lb).
The maximum allowable
weight of the trailer may be
lower based on the weight of
the passengers and cargo in
your trailer.
The maximum trailer weight
rating 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.
Trailer Load Balance
The correct trailer load
balance must be maintained to
ensure trailer stability.
Incorrect load balance is a
leading cause of trailer sway.
The trailer tongue weight (1)
should be 10–15% of the
loaded trailer weight (2). Some
specific trailer types, such as
boat trailers, fall outside of
this range. Always refer to the
trailer owner’s manual for therecommended trailer tongue
weight for each trailer. Never
exceed the maximum loads for
your vehicle, hitch, and trailer.
After loading the trailer,
separately weigh the trailer
and then the trailer tongue
and calculate the trailer load
balance percentage to see if
the weights and distribution
are appropriate for your
vehicle. If the trailer weight is
too high, it may be possible to
transfer some of the cargo
into your vehicle. If the trailer
tongue weight is too high or
too low, it may be possible to
rearrange some of the cargo
inside of the trailer.
Do not exceed the maximum
allowable tongue weight for
your vehicle. Use the shortest
hitch extension available to
position the hitch ball closer to
your vehicle. This will help
reduce the effect of the trailer
tongue weight on the trailer
hitch and the rear axle.

Driving and Operating 365
If a cargo carrier is used in the
trailer hitch receiver, choose a
carrier that positions the load
as close to the vehicle as
possible. Make sure the total
weight, including the carrier, is
no more than half of the
maximum allowable tongue
weight for the vehicle or
227 kg (500 lb), whichever
is less.
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going
by, and rough roads can affect
the trailer and the hitch.
Never attach rental hitches or
other bumper-type hitches.
Only use frame-mounted
hitches that do not attach to
the bumper.Always seal any holes in your
vehicle if the trailer hitch
removed. If not sealed, dirt,
water, and carbon monoxide
(CO) from the exhaust may
enter your vehicle. See Engine
Exhaust
0271.
Consider using mechanical
sway controls with any trailer.
Ask a trailering professional
about sway controls or refer
to the trailer manufacturer's
recommendations and
instructions.
Tires
.Do not tow a trailer while
using a compact spare tire
on the vehicle.
.Tires must be properly
inflated to support loads
while towing a trailer. See
Tires 0413 for instructions
on proper tire inflation.
Safety Chains
Always attach chains between
the vehicle and the trailer, and
attach the chains to the holes
on the trailer hitch platform.
Instructions about safety
chains may be provided by the
hitch manufacturer or by the
trailer manufacturer.
Cross the safety chains under
the tongue of the trailer to
help prevent the tongue from
contacting the road if it
becomes separated from the
hitch. Always leave just
enough slack so the
combination can turn. Never
allow safety chains to drag on
the ground.

366 Driving and Operating
Trailer Brakes
Loaded trailers over 450 kg
(1,000 lb) must be equipped
with brake systems and with
brakes for each axle. Trailer
braking equipment conforming
to Canadian Standards
Association (CSA) requirement
CAN3-D313, or its equivalent,
is recommended.
State or local regulations may
require trailers to have their
own braking system if the
loaded weight of the trailer
exceeds certain minimums
that can vary from state to
state. Read and follow the
instructions for the trailer
brakes so they are installed,
adjusted, and maintained
properly. Never attempt to tap
into your vehicle's hydraulic
brake system. If you do, both
the vehicle anti-lock brakes
and the trailer brakes may not
function, which could result in
a crash.
Trailer Lamps
Always check all trailer lamps
are working at the beginning
of each trip, and periodically
on longer trips.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.

{Warning
The Data Link Connector
(DLC) is used for vehicle
service and Emission
Inspection/Maintenance
testing. See Malfunction
Indicator Lamp (Check
Engine Light)0118. A device
connected to the DLC —
such as an aftermarket fleet
or driver-behavior tracking
device —may interfere with
vehicle systems. This could
affect vehicle operation and
cause a crash. Such devices
may also access information
stored in the vehicle’s
systems.

many ways if the wrong brake
parts are installed or if parts
are improperly installed.
The Brake Fade Warning
Assist system is designed for
use with the factory-installed
brake pads or GM approved
replacement pads. If the brake
pads on the vehicle need to be
replaced, use GM-approved
brake pads. If this is not done,
the brake fade warning
system may not function
properly.
High Performance Brake
Lining Car Wash and
Extended Parking Care
If equipped with high
performance brake
components, binding or
clunking may be noticeable
after extended parking or in
cold weather when the brakes
have been wet, such as when
driving in the rain or after a
car wash. The clunking is
normal for brakes with high
performance brake linings and
does not affect the operationof the brakes. When driving,
normal braking will allow for
the brakes to feel smooth and
the clunking to go away. If the
vehicle is washed before
overnight parking or long term
storage, drive it and apply the
brakes several times to
thoroughly dry the brakes.
Brake Rotor Wear
(V-Series Blackwing With
J57 Carbon Ceramic
Rotors)
The V-Series Blackwing with
J57 has carbon ceramic brake
rotors. The rotors should be
visually inspected whenever
the brake pads are replaced.
Carbon ceramic brake rotors
also need to be weighed
before brake pads are
replaced to confirm that the
rotor mass is greater than the
wear-out mass printed on the
rotor. The rotor can be reused
if the weight of the rotor is
above the mass limit. Carbon
ceramic brake rotors
inspection and weighing
methods can be found in the
service manual.
V-Series Blackwing Brake
Burnish Procedure for
Corrosion Cleanup
Corrosion spotting and
grooving on the brake rotor
surface may appear after the
vehicle sits for an extended
period of time, especially in
high humidity. This corrosion
may result in brake pulsation
and noise. To help restore
optimal braking performance
and reduce noise, complete
the following procedure:
Caution
Performing the brake
burnish procedure on a base
brake system can result in
brake damage.
Perform this procedure only
on dry pavement, in a safe
manner, and in compliance
