if equipped. SeeHead-Up Display
(HUD) 0110.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) gear, when
available, will allow the vehicle to
gain more traction.
The Manual Paddle Shift system
can be deactivated by pulling the
D (Drive) switch on the center
console.
With the transmission in D (Drive),
pull the right + paddle or the left
− paddle to place the transmission
in Temporary Manual Paddle
Shift mode.
To exit Temporary Manual Paddle
Shift mode do one of the following:
. Hold the + paddle for more than
one second.
. Drive at a steady speed without
manual shifts or aggressive
cornering for more than
six seconds.
. Bring the vehicle to a stop. While the Manual Paddle Shift
feature is active, the transmission
will automatically downshift through
the gears as the vehicle slows. The
transmission will select 1 (First) gear
as the vehicle stops. From a stop,
the vehicle will start from and hold
1 (First) gear unless Manual Paddle
Shifts are used to shift into a
different gear, or D (Drive) is
selected.
To cause the transmission to
downshift to the lowest gear
possible for the vehicle speed, in
Manual Paddle Shift or Temporary
Manual Paddle Shift mode:
.
Pull and briefly hold the
−paddle. If the paddle continues
to be held as the vehicle slows,
downshifts will continue as
vehicle speed allows.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
vehicle speed is too fast or too slow,
nor will it allow a start from any gear
other than 1 (First) gear.
When in Manual Paddle Shift mode,
if upshifting does not occur when
needed, vehicle speed will be limited to protect the engine. When
in Temporary Manual Paddle Shift
mode, the transmission will
automatically upshift if the
accelerator pedal is pressed all the
way to the floor.
Manual Paddle Shift can be used
with cruise control. See
Cruise
Control 0196.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
To prevent damage to the
powertrain, Manual Paddle
downshifts to a lower gear cannot
be done above certain speeds.

Double Paddle Declutch allows the
vehicle to temporarily disconnect
the engine from the wheels
–similar
to N (Neutral). This feature is
activated by pulling and holding
both the + paddle and −paddle at
the same time while the vehicle is in
R (Reverse), D (Drive), or M
(Manual Mode). The vehicle will
remain in this condition until both
the + paddle and −paddle are
released.
The R, D, or M indicator on the
center shift console will flash red to
indicate that the vehicle is in Double
Paddle Declutch. In addition, the
current gear state indicator in the
DIC may dim to gray to indicate that
the vehicle is in Double Paddle
Declutch.
To exit Double Paddle Declutch,
release both the + paddle and −
paddle. The engine will reconnect to
the wheels and the shift indicator
will stop flashing. There are two
Double Paddle Declutch exit styles:

178 Driving and Operating
Rapid Exit :This is intended for
use at a closed course race track
and not on public roads. Engine
power is reapplied to the wheels
quickly to support spirited driving.
The rate of launch is dependent on
how much the accelerator pedal is
pressed when the paddles are
released: The further the accelerator
pedal is pressed, the greater the
rate of launch. Tire spin may occur
with the accelerator pedal pressed
and the Traction Control System
(TCS) turned off.
This launch occurs when both of
these conditions are met:
. Vehicle speed is below
10 km/h (6 mph).
. Both the + paddle and −paddle
are released at the same time.
With the accelerator fully pressed
and the engine at the rev limiter,
peak performance only occurs if the
paddles are released within a short
period of time after reaching the rev
limit (i.e., a few seconds). Standard Exit :
Engine power is
reapplied to the wheels gently to
support normal vehicle operation on
public roads.
This occurs when paddles are
released under any of the these
conditions:
. Vehicle speed is above
10 km/h (6 mph).
. The vehicle is in R (Reverse).
. The + paddle and −paddle are
not released at the same time.
If the vehicle was in Temporary
Manual Paddle Shift mode before
entering Double Paddle Declutch,
the vehicle will return to D (Drive)
with automatic shifting upon exiting
Double Paddle Declutch.
{Warning
When exiting Double Paddle
Declutch, the vehicle may move
rapidly. You could lose control
and cause a crash with nearby
people or objects. Be ready to (Continued)
Warning (Continued)
release the accelerator pedal or
apply the brakes immediately if
the vehicle moves too quickly. Do
not use the Double Paddle
Declutch when people or objects
are near.

Brakes
Electric Brake Boost
Vehicles equipped with electric
brake boost have hydraulic brake
circuits that are electronically
controlled when the brake pedal is
applied during normal operation.
The system performs routine tests
and turns off within a few minutes
after the vehicle is shutdown. Noise
may be heard during this time. If the
brake pedal is pressed during the
tests or when the electric brake
boost system is off, a noticeable
change in pedal force and travel
may be felt. This is normal.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while
braking hard.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 105.
ABS does not change the time
needed to get a foot on the brake
pedal and does not always
decrease stopping distance. If you
get too close to the vehicle ahead,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room ahead to stop,
even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly.
Hearing and feeling ABS operate is
normal.
Braking in Emergencies
ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking.
Electric Parking Brake
If equipped, the Electric Parking
Brake (EPB) can always be
activated, even if the ignition is off.
To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.

182 Driving and Operating
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak/
Electronic Stability Control (ESC)
system. These systems help limit
wheel spin and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, TCS applies
the brakes to the spinning wheel
and reduces engine power (by
closing the throttle and managing
engine spark) to limit wheel spin.
StabiliTrak/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control 0196.
If the driver disables TCS, cruise
control will disengage. Cruise
control will also be disabled if
Performance Traction Management
(PTM) is selected, or if StabiliTrak is
turned off.
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 0159
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
. Flash when ABS is active
. 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
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.

Mode Description
uWeather :Weather Mode is used
for slippery surfaces to help control
wheel speed. This can compromise
the acceleration on dry asphalt.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see If the
Vehicle Is Stuck 0159. See “Driver
Mode Attributes,” later in this
section.
sTour : Use for normal city and
highway driving to provide a
smooth, soft ride. This setting
provides a balanced setting
between comfort and handling. This
is the standard mode. See “Driver
Mode Attributes,” later in this
section.
rSport : Use where road
conditions or personal preference
demand a more controlled
response. Used for spirited driving.
In this mode, the vehicle monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected. These features maintain lower
transmission gears to increase
available engine braking and
improve acceleration response. The
vehicle will exit this feature and
return to normal operation after a
short period when no spirited driving
is detected. See
“Driver Mode
Attributes,” later in this section.
tTrack :Track Mode is used for
closed race tracks. Use when
maximum vehicle handling is
desired.
When in Track Mode, the dual
clutch transmission and steering will
function similar to Sport Mode. The
accelerator pedal is adjusted to give
maximum control during the highest
level of spirited driving. See “Driver
Mode Attributes,” later in this
section.
qMy Mode : My Mode is used to
personalize everyday driving. This
mode is designed to allow the driver
to configure vehicle sub-systems to
their own preference for city or
normal driving.
