Performance Shift Features
when spirited driving is
detected. These features
maintain lower transmission
gears to increase available
engine braking and improve
acceleration response. The
vehicle will exit this feature
and return to normal operation
after a short period when
spirited driving is no longer
detected. The steering
changes to provide more
precise control. If the vehicle
has Magnetic Ride Control, the
suspension changes to
provide better cornering
performance.See
“Mode Selection
Attributes” later in this
section.
Snow/Ice Mode

Launch Control
If equipped, Launch Control is
available within Competitive
Driving Mode and PTM to
allow 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 or any of the PTM
modes are selected. The
traction off light comes on in
the instrument cluster and
the appropriate DIC
message displays.
.The vehicle is not moving.
.The steering wheel is
pointing straight.
Automatic Transmissions
.The brake pedal is 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 reapply the accelerator
to wide open throttle.

Driving and Operating 301
Launch Control will initially
limit engine speed as you
rapidly apply 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
Competitive Driving Mode
or PTM.
Competitive Driving Mode,
PTM, and Launch Control are
systems designed for a closed
course race track and not
intended for public roads. The
systems are not intended to
compensate for lack of driver
experience or familiarity with
the race track.Limited-Slip
Differential
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/
Electronic Stability
Control (ESC).
For vehicles with eLSD, driven
under severe conditions, the
rear axle fluid should be
changed. See Competitive
Driving Mode 0298 and
Maintenance Schedule 0469.
Cruise Control
{
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.
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).
If equipped with a manual
transmission, the cruise
control will remain active when

304 Driving and Operating
The speedometer reading can
be displayed in either English
or metric units. See
Instrument Cluster (Base
Level)0106 or
Instrument Cluster (Uplevel)
0 108. The increment value
used depends on the units
displayed.
Passing Another Vehicle
While Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed.
When you take your foot off
the pedal, the vehicle will slow
down to the previous set
cruise speed.
While pressing the accelerator
pedal or shortly following the
release to override cruise,
briefly applying SET− will
result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will
work on hills depends upon
the vehicle speed, load, and
the steepness of the hills. When going up steep hills, you
might have to step on the
accelerator pedal to maintain
your speed. When going
downhill, the cruise control
system may automatically
brake to slow the vehicle
down. Also, you may have to
brake or shift to a lower gear
to keep your speed down.
If the brake pedal is applied,
cruise control disengages.
Ending Cruise Control
There are five ways to end
cruise control:
.Step lightly on the brake
pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.Press the clutch pedal for
several seconds or shift to
Neutral (manual
transmissions).
.PressJ.
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 (Advanced)
If equipped, Adaptive Cruise
Control (ACC) allows the
cruise control set speed and
following gap to be selected.
Read this entire section
before using this system. The
following gap is the following
time 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. ACC uses
camera and radar sensors.
See Radio Frequency
Statement 0494.
If a vehicle is detected in your
path, ACC can speed up the
vehicle or apply limited,
moderate braking to maintain

damaged, and the 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 for
advice and information
about towing a trailer with
the vehicle.
Driving with a Trailer
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. Read this
section carefully before pulling
a trailer.When towing a trailer:
.Become familiar with, and
follow all state and local laws
that apply to trailer towing.
These requirements vary
from state to state.
.State laws may require the
use of extended side view
mirrors. If your visibility is
limited or restricted while
towing, install extended side
view mirrors on your vehicle,
even if not required.
.Do not tow a trailer during
the first 800 km (500 mi) of
vehicle use to prevent
damage to the engine, axle,
or other parts.
.Perform the first oil change
before heavy towing.
.Do not drive over 800 km/h
(50 mph) and do not make
starts at full throttle during
the first 800 km (500 mi) of
trailer towing.
.Tow in D (Drive). If the
transmission downshifts too
often, a lower gear may be
selected using Manual Mode.
See Manual Mode
(Electronic Shifter)
0281 or
Manual Mode (Mechanical
Shifter) 0280.
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:
.Adaptive Cruise
Control (ACC)
.Super Cruise Control
.Park Assist
.Automatic Parking
Assist (APA)
.Reverse Automatic
Braking (RAB)

Towing with a Stability
Control System
When towing, the stability
control system might be
heard. The system reacts to
vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is
normal when towing heavier
trailers.
Following Distance
Stay at least twice as far
behind the vehicle ahead as
you would when driving
without a trailer. This can help
to avoid heavy braking and
sudden turns.
Passing
More passing distance is
needed when towing a trailer.
The combination of the vehicle
and trailer will not accelerate
as quickly and is much longer
than the vehicle alone. It is
necessary to go much farther
beyond the passed vehiclebefore returning to the lane.
Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the
steering wheel with one hand.
To move the trailer to the left,
move that hand to the left. To
move the trailer to the right,
move that hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Caution
Turn more slowly and make
wider arcs when towing a
trailer to prevent damage to
your vehicle. Making very
sharp turns could cause the
trailer to contact the vehicle.
Make wider turns than normal
when towing, so trailer will not
go over soft shoulders, over
curbs, or strike road signs,
trees, or other objects. Always signal turns well in advance.
Do not steer or brake
suddenly.
Driving on Grades
Reduce speed and shift to a
lower gear before starting
down a long or steep downhill
grade. If the transmission is
not shifted down, the brakes
may overheat and result in
reduced braking efficiency.
Vehicles 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.
When towing at higher
altitudes, engine coolant will
boil at a lower temperature
than at lower 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, preferably on
level ground, with the
