Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport mode
indicator will display in the Driver
Information Center (DIC).
When in Sport or Track mode, the
vehicle will shift automatically but
may hold a lower gear longer than it
would in the normal driving mode
based on braking, throttle input, and
vehicle lateral acceleration. See
Automatic Transmission 0191. The
steering will change to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
will change to provide better
cornering performance.
Competitive Driving Mode can be
accessed through this mode.
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. The
transmission will use 2 (Second) gear
instead of 1 (First) gear when accelerating from a stop. The vehicle
will upshift normally when the vehicle
is moving.
For V-Series only, Snow/Ice mode will
use a different accelerator pedal map
to optimize traction on a slippery
surface. The accelerator pedal will
reduce engine torque at small pedal
inputs. The transmission will also
shift differently to assist in
maintaining traction.
When selected, the Snow/Ice mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see

Launch Control (V-Series Only)
A Launch Control feature is available,
within Competitive Driving Mode
(V-Series) or Performance Traction
Management (V-Series), to allow the
driver to achieve high levels of vehicle
acceleration in a straight line. Launch
Control is a form of traction control
that manages tire spin while
launching the vehicle. This feature is
intended for use during closed course
race events where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available when
the following criteria are met:
. Competitive Driving Mode is
selected (V-Series) or any of the
Performance Traction
Management modes are selected
(V-Series). The TCS light comes on
the instrument panel and the
appropriate DIC message displays.
. The vehicle is not moving.
. The steering wheel is pointing
straight. .
The brake pedal must be firmly
pressed to the floor, equivalent to
a panic brake event.
. The accelerator pedal is rapidly
applied to wide open throttle. (If
the vehicle rolls due to wide open
throttle, release the throttle, press
the brake pedal more firmly, and
re-apply the accelerator to wide
open throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth,
quick release of the brake pedal, while
maintaining the fully pressed
accelerator pedal, will manage
wheel slip.
After the vehicle is launched, the
system continues in Performance
Traction Management (V-Series).
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for use on public roads. The
systems are not intended to

compensate for lack of driver
experience or familiarity with the race
track.
Limited-Slip Rear Axle
(Except V-Series)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard axle
most of the time, but when traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. For vehicles with
limited-slip differential, driven under
severe conditions, the rear axle fluid
should be changed. SeeCompetitive
Driving Mode (FE4 Only) 0201 and
Maintenance Schedule 0307.
Limited-Slip Rear Axle
(V-Series Only)
If equipped, the Electronic
Limited-Slip Differential (ELSD) is
automatically activated. ELSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With ELSD,
the vehicle has:
.
Enhanced high-speed control.
. Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak.
For vehicles with ELSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode (FE4 Only) 0201 and
Maintenance Schedule 0307.
Cruise Control
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
If the StabiliTrak
®system begins to
limit wheel spin while using cruise
control, the cruise control
automatically disengages. See Traction
Control/Electronic Stability Control
0 198. If a collision alert occurs when

Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. The following gap is
the following time (or distance)
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak
®electronic stability
control system activates while ACC is engaged, ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0198. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak electronic stability control
system is disabled.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0171.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.

DRIVING AND OPERATING 211
Warning (Continued)
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
. The sensors are blocked.
. The Traction Control System (TCS)
or electronic stability control
system has activated or been
disabled.
. No traffic or other objects are
being detected.
. There is a fault in the system. The ACC active symbol will not be
displayed when ACC is no longer
active.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic before proceeding. In addition,
the left and right sides of the Safety
Alert Seat will pulse three times,
or three beeps will sound. See
”Alert
Type ”and “Go Notifier” in“Collision/
Detection Systems” underVehicle
Personalization 0137.
When the vehicle ahead drives away,
press +RES or the accelerator pedal to
resume ACC. If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically
applies the electric parking brake to hold the vehicle. The electric parking
brake status light will turn on. See
Parking Brake (Manual)
0195 or
Parking Brake (Electric) 0196. To
release the electric parking brake,
press the accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0127.
{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.

VEHICLE CARE 271
All-Season Tires
This vehicle may come with all-season
tires. These tires are designed to
provide good overall performance on
most road surfaces and weather
conditions. Original equipment tires
designed to GM's specific tire
performance criteria have a TPC
specification code molded onto the
sidewall. Original equipment
all-season tires can be identified by
the last two characters of this TPC
code, which will be“MS.”
Consider installing winter tires on the
vehicle if frequent driving on snow or
ice-covered roads is expected.
All-season tires provide adequate
performance for most winter driving
conditions, but they may not offer the
same level of traction or performance
as winter tires on snow or ice-covered
roads. See Winter Tires 0271.
Winter Tires
This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered
roads. Consider installing winter tires on the vehicle if frequent driving on
ice or snow covered roads is expected.
See your dealer for details regarding
winter tire availability and proper tire
selection. Also, see
Buying New
Tires 0280.
With winter tires, there may be
decreased dry road traction, increased
road noise, and shorter tread life.
After changing to winter tires, be alert
for changes in vehicle handling and
braking.
If using winter tires:
. Use tires of the same brand and
tread type on all four wheel
positions.
. Use only radial ply tires of the
same size, load range, and speed
rating as the original equipment
tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Run-Flat Tires
This vehicle, when new, may have had
run-flat tires. There is no spare tire,
no tire changing equipment, and no
place to store a tire in the vehicle.
The vehicle also has a Tire Pressure
Monitor System (TPMS) that indicates
a loss of tire pressure in any of the
tires.
{Warning
If the low tire warning light displays
on the instrument cluster, the
handling capabilities will be
reduced during severe maneuvers.
Driving too fast could cause loss of
control and you or others could be
injured. Do not drive over 90 km/h
(55 mph) when the low tire warning
light is displayed. Drive cautiously
and check the tire pressures as
soon as possible.
Run-flat tires can be driven on with
no air pressure. There is no need to
stop on the side of the road to change
the tire. Continue driving; however, do

performance, ride and handling,
traction control, and tire pressure
monitoring performance. GM's
TPC Spec number is molded onto
the tire's sidewall near the tire
size. If the tires have an all-season
tread design, the TPC Spec
number will be followed by MS for
mud and snow.
GM recommends replacing worn
tires in complete sets of four.
Uniform tread depth on all tires
will help to maintain the
performance of the vehicle.
Braking and handling performance
may be adversely affected if all the
tires are not replaced at the same
time. If proper rotation and
maintenance have been done, all
four tires should wear out at
about the same time. SeeTire
Rotation 0278 for information on
proper tire rotation. However, if it
is necessary to replace only one
axle set of worn tires, place the
new tires on the rear axle.{Warning
Tires could explode during
improper service. Attempting to
mount or dismount a tire could
cause injury or death. Only your
dealer or authorized tire service
center should mount or
dismount the tires.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H, V,
W, Y, and ZR speed rated tires.
Never exceed the winter tire's
maximum speed capability when
using winter tires with a lower
speed rating.
{Warning
Never drive faster than the speed
the tires are rated, regardless of the
legal speed limit. When frequently
driving the vehicle at high speeds
and/or for prolonged periods of (Continued)
Warning (Continued)
time, check with your vehicle/tire
dealer for the proper type of tires to
use for the specific driving and
weather conditions.
{Warning
Mixing tires of different sizes (other
than those originally installed on
the vehicle), brands, or types may
cause loss of control of the vehicle,
resulting in a crash or other vehicle
damage. Use the correct size, brand,
and type of tire on all four wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel rim
flanges to develop cracks after
many miles of driving. A tire
and/or wheel could fail suddenly
