Driver Mode Customization
The Engine Sound Management,
steering, and suspension drive modes
can be set to the driver’s preference.
See“Driving Mode ”under Vehicle
Personalization 0140. When in the Track main vehicle mode,
you cannot overwrite the Steering or
Suspension settings. These settings
are designed to interact with the
advanced functions in the Track Mode
and cannot be overwritten.
The selections made in the Driving
Mode menu overwrite the main
vehicle mode selection via the buttons
or switch on the center console. In
order to customize and overwrite,
select one of the three settings by
touching the infotainment display.
When in the customization screen for
each system, select one of the
available options:
•
Auto (Follows the MODE switch)
• Tour
• Sport
• Track (V-Series only) The default will be to follow the
vehicle MODE switch settings, but the
main vehicle mode selection for the
currently selected system can be
overwritten using this menu. The
settings selected in this menu will set
the vehicle behavior in all selected
vehicle modes, and will be retained
over each ignition cycle. They do not
have to be reset each time the vehicle
is started.
Locking Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand, or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change. For
vehicles with limited-slip rear axle, the
rear axle fluid should be changed. See
Maintenance Schedule
0359.

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 pedal. Cruise
control cannot be set below 40 km/h
(25 mph).
If the Traction Control/StabiliTrak/
Electronic Stability Control (ESC)
system begins to limit wheel spin
while using cruise control, the cruise control automatically disengages. See
Traction Control/Electronic Stability
Control
0203. If a collision alert
occurs when cruise control is
activated, cruise control is disengaged.
See Forward Collision Alert (FCA)
System 0244. When road conditions
allow cruise control to be safely used,
it can be turned back on.
Cruise control will disengage if either
TCS or StabiliTrak/ESC is turned off.
If the brakes are applied, cruise
control disengages.
J: Press to turn the system on and
off. A white indicator appears in the
instrument cluster when cruise is
turned on.

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. See
Radio Frequency
Statement 0386. 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
(ESC) system activates while ACC is
engaged, ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0203. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak/ESC is disabled.

212 DRIVING AND OPERATING
{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 0173.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.

Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD. The gap setting will
be maintained until it is changed. Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See
Forward Collision Alert
(FCA) System 0244.
