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 or underhood storage compartment
is open.
.The system can be raised or lowered by
the pushbutton, when the vehicle is in
RUN or in accessory 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.
If equipped, 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 prompt the driver if they would
like to “Remember” the location. The driver
can select this function through the steering
wheel controls, see Steering Wheel Controls
0 119.
The driver can also delete stored locations
for the automatic lift.
If the vehicle is raised automatically using
GPS, it will automatically lower once the
vehicle is located about 60 meters (197 feet)
from the programmed location. To disable
this function, turn off the GPS location via
the vehicle Customization Settings. The Front
Lift System will now only operate using the
pushbutton command, and the “Auto Lift
Location Remembered” confirmation
message will not display.

Performance Driving
If equipped, Competitive Driving mode,
Performance Traction Management (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 a race track.
Drivers who prefer to allow the system to
have more control of the engine, brakes,
and suspension are advised to turn on the
normal traction control and StabiliTrak/
Electronic Stability Control (ESC) systems on.
If equipped with E-Ray, there is a
Performance app on the infotainment screen
that shows the vehicle electric and engine
power/torque. See

Limited-Slip Differential
The standard mechanical limited-slip
differential provides 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
Performance Driving 0206 and
Maintenance Schedule 0316.
Stingray, E-Ray, and Z06 Models Only
The Electrical Limited-Slip Differential (eLSD)
located on the rear axle is a hydraulically
actuated clutch system. 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.
.Mode 2 is engaged when both TCS and
StabiliTrak are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak remains on. Vehicle
stability is still the priority, while allowing
for optimized traction out of corners.

220 Driving and Operating
The Collision Alert control is on the steering
wheel. Press
[to set the FCA timing to
Far, Medium, or Near. The first button press
shows the current setting on the DIC.
Additional button presses will change this
setting. The chosen setting will remain until
it is changed and will affect the timing of
both the Collision Alert and the Tailgating
Alert features. The timing of both alerts will
vary based on vehicle speed. The faster the
vehicle speed, the farther away the alert will
occur. Consider traffic and weather
conditions when selecting the alert timing.
The range of selectable alert timings may
not be appropriate for all drivers and driving
conditions.
Following Distance Indicator
The following distance to a moving vehicle
ahead in your path is indicated in following
time in seconds on the Driver Information
Center (DIC). The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is out
of sensor range, dashes will be displayed.
Unnecessary Alerts
FCA may provide unnecessary alerts for
turning vehicles, vehicles in other lanes,
objects that are not vehicles, or shadows.
These alerts are normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not seem to operate
properly, this may correct the issue:
.Clean the outside of the windshield in
front of the rearview mirror.
.Clean the entire front of the vehicle.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
The AEB system may help avoid or reduce
the harm caused by front-end crashes. AEB
also includes Intelligent Brake Assist (IBA).
When the system detects a vehicle ahead in
your path that is traveling in the same
direction that you may be about to crash
into, it can provide a boost to braking or
automatically brake the vehicle. This can
help avoid or lessen the severity of crashes
when driving in a forward gear. Depending
on the situation, the vehicle may automatically brake moderately or hard.
Always wear a seat belt and ensure that all
passengers are properly restrained. This
automatic emergency braking can only occur
if a vehicle is detected. This is shown by the
FCA vehicle ahead indicator being lit. See
Forward Collision Alert (FCA) System
0218.
The system works when driving in a forward
gear between 8 km/h (5 mph) and 135 km/h
(84 mph). It can detect vehicles up to
approximately 60 m (197 ft).
{Warning
AEB is an emergency crash preparation
feature and is not designed to avoid
crashes. Do not rely on AEB to brake the
vehicle. AEB will not brake outside of its
operating speed range and only responds
to detected vehicles.
AEB may not:
.Detect a vehicle ahead on winding or
hilly roads.
.Detect all vehicles, especially vehicles
with a trailer, tractors, muddy
vehicles, etc. (Continued)
