USING STABILITY CONTROL

Electronic Stability Control

The system automatically turns on each
time you switch the ignition on. The
electronic stability control portion of the
system is disabled when the transmission
is in reverse (R) or, on some models, if you
press and hold the electronic stability
control button for more than five seconds
when you apply the brakes and the vehicle
is at a stop. You can switch off the traction
control portion of the system
independently. See Using Traction
Control (page 153).

Note: Do not use the Sport stability control
setting on public roadways.

Some models may also come equipped
with a sport mode which allows the driver
to reduce normal electronic stability
control system intervention and provide a
more spirited driving experience. To enter
sport mode, toggle the stability control
button twice rapidly. The message appears
in the information display that the system
is now in sport mode.

For vehicles equipped with the selectable
drive mode feature, electronic stability
control sport mode is not available. You
can utilize the performance oriented
electronic stability control mode by
selecting track drive mode. In this mode,
electronic stability control intervention is
reduced and tuned specifically for track
use only and is not for use on public roads.
In all of the selectable drive modes, you
can disable traction control and electronic
stability control with the electronic stability
control switch.

Line Lock

(If Equipped)

Line Lock is a feature intended for use at
tracks only and should not be used on
public roadways. Use of this feature will
result in significantly increased rear tire
wear. It is intended to condition the rear
tires to maximize traction prior to track use.
Line Lock maintains brake force at the
front wheels, allowing the rear wheels to
spin with minimal vehicle movement.

This feature is located in the Track Apps
menu. Make selections through the 5-way
information display control and OK button
located on the steering wheel.

Using Line Lock

There are three Line Lock stages:

•

Initiated.

•

Engaged.

•

Off.

Initiating Line Lock

The initiation stage verifies that the vehicle
is ready for Line Lock function, and
confirms driver intent. Follow the prompts
in the information display in to initiate Line
Lock.

The following conditions must be met to
initialize Line Lock:
•

The vehicle is on a level surface.

•

The engine is running.

•

The vehicle is traveling less than
25 mph (40 km/h).

•

Selectable Drive Mode is not in wet
mode (if equipped).

•

There are no electronic stability control
faults.

If you want to cancel Line Lock once it is
initialized, press the left information
display control. Once initiated, Line Lock
is prepared for activation and will remain
initiated up to 25 mph (40 km/h). If vehicle
speed exceeds 25 mph (40 km/h), Line
Lock will be automatically canceled.

Engaging Line Lock

Follow the prompts in the information
display to engage Line Lock after it is
initialized. To engage, firmly apply the
brakes. Then press the OK button. Once
engaged, release the brake pedal. The
front brakes will remain applied and the
rear brakes will release. At this point, the
engagement timer is initiated and shown
on the driver information display.

The following conditions must be met to
engage Line Lock:
•

The vehicle is on a level surface.

•

The engine is running.

•

The vehicle is stopped.

•

The parking brake is not applied.

•

The driver door is closed.

•

The transmission is in a forward gear.

•

Selectable Drive Mode is not in wet
mode (if equipped).

•

There are no electronic stability control
faults.

•

The steering wheel must be in the
straight ahead position.

Releasing Line Lock

While Line Lock is engaged, you can exit
(release) the feature using the OK button.
When you press the OK button, Line Lock
releases immediately and normal vehicle
function will resume. When Line Lock is
engaged, a countdown timer shows the
remaining time before Line Lock is released
automatically. If you exceed the time limit,
or another vehicle condition requires Line
Lock to release, the system will safely
disengage and normal vehicle function will
resume.

Note: If the brake pedal is applied while
Line Lock is engaged, Line Lock
automatically cancels and normal brake
function resumes.

PRINCIPLE OF OPERATION

WARNINGS

To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.

The system may not detect objects
with surfaces that absorb reflection.
Always drive with due care and

attention. Failure to take care may result
in a crash.

Traffic control systems, inclement
weather, air brakes, external motors
and fans may affect the correct

operation of the sensing system.This may
cause reduced performance or false alerts.

The system may not detect small or
moving objects, particularly those
close to the ground.

Note: If your vehicle is equipped with
MyKey™, the sensing system cannot be
turned off when a MyKey™ is present. See
Principle of Operation (page 52).

Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system’s accuracy can be
affected. Do not clean the sensors with
sharp objects.

Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.

Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device
to prevent false alerts.

Note: When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected to prevent the alert.

The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.

The system can be switched off through
the information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information (page 88).

If a fault is present in the system, a warning
message appears in the information
display. See Information Messages
(page 97).

REAR PARKING AID

(If Equipped)

The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than 12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
12 in (30 cm) from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.
