196 DRIVING AND OPERATING
Temporary Tap Shift Mode
To enter Temporary Tap Shift Mode:1. With the transmission in D (Drive) and not in Permanent
Tap Shift Mode, the Tap Shift
controls will activate a
Temporary Tap Shift Mode,
allowing the transmission to be
manually shifted.
2. To shift to the lowest available gear, press and hold the left
control.
3. To deactivate, hold the right control briefly. Automatic shifts
return after no manual shifts
have been done for seven to
10 seconds.
While using Tap Shift, the vehicle will
have firmer, quicker shifting. This can
be used for sport driving or when
climbing or descending hills, to stay in
gear longer, or to downshift for more
power or engine braking. The transmission will only allow
shifting into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). If shifting is
prevented for any reason, the M or D
will flash in the instrument cluster.
The transmission will not
automatically shift to the next higher
gear if the engine rpm is too high.
It will only automatically shift to the
next lower gear if the engine rpm is
much too low.Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode. See
Driver Mode Control
0202.
Press MODE to activate AWD. AWD is
active in both AWD and Sport Modes.
The AWD system delivers power to all
four wheels and the system adjusts as
needed to improve traction.

200 DRIVING AND OPERATING
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
R (Reverse). The vehicle must come to
a complete stop on a grade for HSA to
activate.Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC).
These systems help limit wheel spin
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any of
the drive wheels are spinning or
beginning to lose traction. On an
All-Wheel Drive (AWD) vehicle in
AWD or Sport Mode, the system will
operate if it senses that any of the
wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning
wheels and reduces engine power to
limit wheel spin.
StabiliTrak/ESC activates when the
system senses a discrepancy between
the intended path and the direction
the vehicle is actually traveling.StabiliTrak/ESC selectively applies
braking pressure at any one of the
vehicle's brakes to help steer the
vehicle in the direction which you are
steering.
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 0176 and “Turning
the Systems Off and 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 may display in the
Driver Information Center (DIC),
and
dcomes 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. If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on and
stays on, the vehicle may need more
time to diagnose the problem. If the
condition persists, see your dealer.

AWD :AWD Mode provides drive
torque to all four wheels. Select AWD
to improve traction and control on
slippery road surfaces, such as gravel,
sand, wet pavement, snow, and ice For
more information on AWD Mode, see
All-Wheel Drive 0196.
Snow/Ice (FWD Vehicles Only) :
Snow/Ice Mode improves vehicle
acceleration on snow and ice covered
roads. This mode will adjust
acceleration to optimize traction on a
slippery surface. The accelerator pedal
will reduce engine torque at small
pedal inputs.
Off-Road : Use this mode for off-road
recreational driving. When active,
Off-Road Mode modifies accelerator
pedal response, AWD torque, TCS,
ABS and ESC settings. Choosing
Off-Road Mode also engages AWD.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. Cruise control does
not work at speeds below about
40 km/h (25 mph).
If the Traction Control System (TCS)
or StabiliTrak/Electronic Stability
Control (ESC) system begins to limit
wheel spin while using cruise control,
cruise control automatically disengages. See
Traction Control/
Electronic Stability Control 0200. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision Alert
(FCA) System 0226. 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.

moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement0359.
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 ACC is controlling your vehicle
speed when the traction control
system (TCS) or StabiliTrak electronic
stability control system activates, ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control 0200. 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.
{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 0166.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
(Continued)
Warning (Continued)
.Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
5:Press to turn the system on or
off. The indicator turns white on the

if necessary. When braking is active,the
brake lamps will come on. The
automatic braking may feel or sound
different than if the brakes were
applied manually. This is normal.
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.
Vehicles in front of your vehicle
that have a rear aspect that is low,
small, or irregular.
. An empty truck or trailer that has
no cargo in the cargo bed.
. Vehicles with cargo extending
from the back end.
. Non-standard shaped vehicles,
such as vehicle transport, vehicles
with a side car fitted, or horse
carriages.
. Vehicles that are low to the road
surface.
. Objects that are close to the front
of your vehicle.
. Vehicles on which extremely heavy
cargo is loaded in the cargo area
or rear seat.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
.
The sensors are blocked.
. The Traction Control System (TCS)
or StabiliTrak/ESC has activated or
been disabled.
. There is a fault in the system.
. The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC
is temporarily unavailable.

Electric Brake Control Wiring
Provisions
If equipped, (four) blunt-cut wires are
near the driver's feet for an
aftermarket electric trailer brake
controller as part of the trailer wiring
package. The harness contains the
following circuits: Electric Trailer
Brakes Blue
Battery Feed Red/Black or
Red/Blue
Brake Apply
Signal White/Blue
Ground Black
Refer to the aftermarket electric trailer
brake controller owner's manual to
determine wire color coding of the
electric trailer brake controller. The
wire colors on the brake controller
may be different from the vehicle.
It may be necessary to have a technician connect the 12-volt power
to the engine compartment fuse block.
The electric trailer brake controller
should be installed by your dealer or a
qualified service center.
Trailer Lamps
Always check that all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.
Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals should illuminate to
indicate the vehicle is turning,
changing lanes, or stopping. When
towing a trailer, the arrows on the
instrument cluster will illuminate
even if the trailer is not properly
connected or the bulbs are
burned out.
Trailer Sway Control (TSC)
Vehicles with StabiliTrak/Electronic
Stability Control (ESC) have a Trailer
Sway Control (TSC) feature. Trailer
sway is unintended side-to-side
motion of a trailer while towing. If the
vehicle is towing a trailer and the TSC
detects that sway is increasing, the
vehicle brakes are selectively applied
to help reduce excessive trailer sway.
If equipped with the Integrated Trailer
Brake Control (ITBC) system, and the
trailer has an electric brake system,
StabiliTrak/ESC may also apply the
trailer brakes.
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak/ESC warning
light will flash on the instrument
cluster. Reduce vehicle speed by
gradually removing your foot from the
accelerator pedal. If trailer sway
continues, StabiliTrak/ESC can reduce
engine torque to help slow the vehicle.
TSC will not function if StabiliTrak/
ESC is turned off. See
Traction Control/
Electronic Stability Control 0200.
