Driving and Operating 201vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow. TCS and
StabiliTrak/ESC will automatically
turn on when cruise control is set.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See If the Vehicle Is Stuck 0 176

On ” later in this section. The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin.
.
Flash when StabiliTrak/ESC is
activated.
.
Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
d comes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.

Driver Mode Control Driver Mode Control attempts to add
a sportier feel, provide a more
comfortable ride, or assist in
different weather conditions or
terrain. This system simultaneously
changes the software calibration of
various sub-systems. Depending on
the option package, available
features, and mode selected, the
suspension, steering, and
powertrain will change calibrations
to achieve the desired mode
characteristics. If equipped, the vehicle may have
the following modes: All-Wheel
Drive (AWD), Tour, Sport, and/or
Tow/Haul. When not in AWD, the
vehicle is in Front-Wheel Drive
(FWD) which will provide better fuel
economy. All drive modes may
display indicator or mode on
message in the Driver Information
Center (DIC) except FWD.
AWD Mode
AWD Mode is intended for
conditions which demand more
traction. In AWD Mode, the AWD
system delivers power to all four
wheels and the system adjusts as

Mode, the steering and suspension
will change to provide more precise
control and better cornering
performance. Sport Mode is only
available on vehicles equipped with
Real Time Damping. Sport Mode
also changes the StabiliTrak and
AWD settings to allow more
wheel slip.
Tow/Haul Mode If equipped, Tow/Haul Mode can
assist when towing or hauling a
heavy load. It changes transmission
shift patterns, and increases trailer
sway control assistance. See
Driving Characteristics and Towing
Tips 0 234 . Tow/Haul Mode is
available on vehicles with the Trailer
Towing Package. Cruise Control With cruise control the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{ WarningCruise 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.

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 0 221 .
Alerting the Driver
If ACC is engaged, driver action
may be required when ACC cannot
apply sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, a series
of red lights will flash on the
windshield. Either eight beeps will
sound from the front, or both sides
of the Safety Alert Seat will pulse five times. See “ Collision/Detection
Systems ” under Vehicle
Personalization 0 137 .
See Defensive Driving 0 166 .
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster.
The vehicle ahead indicator only
displays when a vehicle is detected

220 Driving and Operating
{ WarningThe Park Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with Park Assist,
always check the area around the
vehicle and check all mirrors
before backing.
The instrument cluster may have a
Park Assist display with bars that
show “ distance to object ” and object
location information for RPA. As the object gets closer, more bars light
up and the bars change color from
yellow to amber to red.
When an object is first detected in
the rear, one beep will be heard
from the rear, or both sides of the
Safety Alert Seat will pulse two
times. When an object is very close,
<0.6 m (2 ft) in the vehicle rear, five
beeps will sound from the rear,
or both sides of the Safety Alert
Seat will pulse five times.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA shows a red
warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming
