Front Lift System
A two-position lift actuator (one per
damper) with 35 mm (1.5 in) of
stroke will hydraulically raise the
front of the vehicle to provide
approximately 50 mm (2 in) of increased clearance in
approximately three seconds (height
and time will vary by vehicle). The
Front Lift System will allow you to lift
the front of the vehicle to enter a
driveway, driving over curbs, speed
bumps or onto ramps or a trailer.
To use the Front Lift System, press
the button on the center console to
raise or lower the vehicle. This
feature can be operated at speeds
up to 38 km/h (24 mph) when the
engine is running. The system
functions based on the vehicle’
s
state or operating mode: .
The system will not raise up
when the doors are open.
. The system can be raised or
lowered by the pushbutton,
when the vehicle is in RUN or in
ACC mode.
. If the vehicle is in the raised
position and is driven at speeds
above 38 km/h (24 mph), it will
automatically lower.
. If the vehicle is turned off, it will
automatically lower.
. If a vehicle door is opened
during lowering, the movement
will pause for 15 seconds then
continue to lower, but at a
slower rate.
The front height can be raised
automatically using GPS navigation
in the vehicle. The vehicle will
automatically lift in up to 1,000
programmable locations. Once the
button is pushed, a notification will
appear on the Driver Information
Center (DIC) and ask the driver if
they would like to “Remember”the
location. The driver can select this
function through the steering wheel

“Lift System Unavailable” if the
following occur:
. Any doors are ajar.
. The hood is open. .
The vehicle is moving over
38 km/h (24 mph).
. Too many lift requests within a
short period.
The Front Lift System should not be
used to service the vehicle. Do not
place anything or body parts under
the vehicle while lifted. See
Recommended Fluids and
Lubricants 0295.
Competitive Driving Mode
If equipped, Competitive Driving
Mode, PTM, and Launch Control are
systems designed to allow
increased performance while
accelerating and/or cornering. This
is accomplished by regulating and
optimizing the engine, brakes, and
suspension performance. These
modes are for use at a closed
course race track and are not
intended for use on public roads.
They will not compensate for driver
inexperience or lack of familiarity
with the race track. Drivers who
prefer to allow the system to have
more control of the engine, brakes, and suspension are advised to turn
the normal traction control and
StabiliTrak/ESC systems on.
Competitive Driving Mode
Competitive Driving Mode allows full
engine power while StabiliTrak/ESC
helps maintain directional control of
the vehicle by selective brake
application. In this mode, the TCS is
off and Launch Control is available.
Adjust your driving style to account
for the available engine power. See
“Launch Control”
later in this
section.

Performance Traction
Management (PTM) (if
equipped)
PTM integrates the TCS,
StabiliTrak/ESC, and Magnetic Ride
Control systems to provide
improved and consistent
performance when cornering. The
amount of available engine power is based on the mode selected, track
conditions, driver skill, and the
radius of each corner.
This light is on when the vehicle is
in the PTM Mode. To select this
optional handling mode, the vehicle
mode must be in Track. Then
quickly press

Launch Control (Sport and
Track Mode Only)
A Launch Control feature is
available, within Competitive Driving
Mode or PTM, on all vehicles to
allow the driver to achieve high
levels of vehicle acceleration in a
straight line. Launch Control is a
form of TCS that manages tire spin,
and transmissions clutch, 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 or any
of the PTM Modes are selected
(if equipped).
. The vehicle is not moving. .
The wheels and steering wheel
are pointing straight.
Launching the Vehicle
. Ensure the vehicle is in
Competitive Driving Mode or any
of the PTM modes.
. The brake pedal must be firmly
pressed to the floor, equivalent
to a panic brake event.
. While maintaining the brake
pedal, 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’ s to stabilize.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage tire slip and transmissions

clutch. 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 use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.
Caution
The new vehicle break-in period
should be completed before using
the launch control feature,
otherwise performance will be
limited and damage may occur to
the powertrain/engine. SeeNew
Vehicle Break-In 0163.
Limited-Slip Differential
(without Z51)
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. See
Competitive Driving
Mode 0192 and
Maintenance Schedule 0286.
Limited-Slip Differential
(with Z51)
The Electronic Limited-Slip
Differential (eLSD) is a hydraulically
actuated clutch system inside the
transaxle. It can infinitely vary the
clutch engagement between 0 and
2250 N*m (1659 lb-ft) of breakaway
torque between the rear wheels.
When necessary it responds from
open to full engagement in fractions
of a second. Smaller clutch
adjustments happen even faster.
The eLSD:
.
Uses the vehicle sensors and
driver inputs to determine the
optimum amount of clutch
engagement for the conditions. .
Improves traction while
cornering by changing the
engagement to achieve a
balance between directional
control and acceleration.
. Provides optimal engagement
for high-speed control and
stability without affecting precise
steering and turn-in.
. Improves vehicle stability during
spirited driving and evasive
maneuvers. It is fully integrated
with the Active Handling and
Performance Traction
Management (PTM) systems (if
equipped).
There are unique calibrations based
on the Traction Control System
(TCS) setting. eLSD modes change
automatically when the traction
control button is pressed. No unique
input from the driver is required.
. Mode 1 is the standard mode
when the vehicle is started.
It provides a touring calibration
with an emphasis on vehicle
stability. Mode 1 is also used in
PTM Wet mode.
