{Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If you are
stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
While in Sport Mode, the vehicle
monitors driving behavior, 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 these features
and return to normal operation after a short period when no spirited
driving is detected. See
Driver Mode
Control on page 9-31.

Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5-23. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.

9-28 Driving and Operating
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch for the
EPB is on the instrument panel, to
the left of the steering wheel. The
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.The system has a red parking brake
status light and an amber parking
brake warning light. See
Parking
Brake Light on page 5-22 and
Service Electric Parking Brake Light
on page 5-23. There are also
parking brake-related Driver
Information Center (DIC) messages.
See Brake System Messages on
page 5-36. In case of insufficient
electrical power, the EPB cannot be
applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Lift up the EPB switch momentarily.
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See
Parking Brake
Light on page 5-22.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is

Driving and Operating 9-33
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. The
transmission will use 2 (Second)
gear instead of 1 (First) gear when
accelerating from a stop. The
vehicle will upshift normally when
the vehicle is moving. The
LF3 models will use a different
accelerator pedal map instead of
using 2 (Second) gear from stop.
The accelerator pedal will reduce
engine torque at small pedal inputs.
The transmission will also shift
differently to assist in maintaining
traction.
When selected, the Snow/Ice Mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, seeIf the
Vehicle Is Stuck on page 9-10.
Track Mode (LF3 Only)
Use when maximum vehicle
handling is desired. When selected, the Track Mode
indicator will display in the DIC.
When in Track Mode, the automatic
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. The
MagneRide will be set to the
optimum level for vehicle
responsiveness. Competitive Driving
Mode can be accessed through
this mode.
Competitive Driving Mode
(LF3 Only)
To select this optional handling
mode, press the
Ybutton quickly
two times and the DIC will display
the appropriate message. While in
the Competitive Driving Mode, the
traction off light
iand StabiliTrak
OFF light
gwill come on in the
instrument cluster. TCS does not
limit wheel spin, the Electronic
Limited-Slip Differential (ELSD) allows increased vehicle agility, and
more effort is required to turn the
steering wheel. See
“Limited–Slip
Differential (LF3 Only)” following.
Adjust your driving accordingly.
Press the
Ybutton again, or turn
the ignition to ACC/ACCESSORY
and restart the vehicle, to turn TCS
back on. The traction off light
iand

9-34 Driving and Operating
Limited-Slip Differential
(LF3 Only)
If equipped, the Electronic Limited
Slip Differential (ELSD) is
automatically activated. ELSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With ELSD, the
vehicle has:
.Enhanced high-speed control.
.Improved traction through
corners, allowing more
acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak.
For vehicles with limited slip
differential, driven under severe
conditions, the rear axle fluid should
be changed. See Competitive
Driving Mode (LF3 Only) on
page 9-33 andMaintenance
Schedule on page 11-3.
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 StabiliTrak
®system begins to
limit wheel spin while using cruise
control, the cruise control
automatically disengages. See
Traction Control/Electronic
Stability Control on page 9-30. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System on page 9-52.
When road conditions allow the
cruise control to be safely used,
cruise control can be turned
back on.
If the brakes are applied, the cruise
control disengages.

9-40 Driving and Operating
Reducing Speed While ACC is at a
Set Speed
If ACC is already activated, do one
of the following:
.Use the brake to get to the
desired lower speed. Press
SET–down and release the
accelerator pedal. The vehicle
will now cruise at the lower
speed.
.Press and hold SET– down until
the desired lower speed is
reached, then release it.
.To decrease the vehicle speed in
smaller increments, press SET−
down to the first detent. For
each press, the vehicle goes
about 1 km/h (1 mph) slower.
.To decrease the vehicle speed in
larger increments, press SET−
down to the second detent. For
each press, the vehicle speed
decreases to the next 5 km/h
(5 mph) mark on the
speedometer. The speedometer reading can be
displayed in either English or metric
units. See
Instrument Cluster on
page 5-10. The increment value
used depends on the units
displayed.
Selecting the Follow Distance
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
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,
if equipped. Subsequent presses
cycle the gap button through three
settings: Far, Medium, or Near. 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 on
page 9-52.

Driving and Operating 9-51
APA will instruct the vehicle to stop
once a large enough space is found.
Follow the instructions in the DIC.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering
wheel will briefly vibrate as a
reminder to remove hands from the
steering wheel. Check surroundings
and continue braking or accelerating
as needed, and be prepared to stop
to avoid vehicles, pedestrians,
or objects.
If the vehicle is in R (Reverse), but
does not steer into the expected
space, this may be because the
system is maneuvering the vehicleinto a previously detected space.
The APA system does not need
service.
If the vehicle exceeds 10 km/h
(6 mph), APA is automatically
disengaged and automatic steering
will turn off. A DIC progress arrow
displays the status of the parking
maneuver. Depending on the space
size, additional maneuvers may be
required, and there will be additional
instructions. When changing gears,
allow the automatic steering to
complete before continuing the
parking maneuver. Upon successful
completion of a maneuver, APA will
beep and display a PARKING
COMPLETE message. Place the
vehicle in P (Park).
APA may automatically disengage if:
.The steering wheel is used by
the driver.
.The maximum allowed speed is
exceeded.
.There is a failure with the APA
system.
.Electronic stability control or
antilock brakes are activated.
.A high priority vehicle message
is displayed in the DIC.
.An incoming call is received
through a connected phone.
Disconnect the phone from the
vehicle to prevent APA from
disengaging.
To cancel APA, press the APA
button again.
When the System Does Not Seem
to Work Properly
The APA system may require a
short period of driving along curves
to calibrate.

and/or the Active Emergency
Braking System can help to avoid a
crash or reduce crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a flashing red
alert on the windshield and rapidly
beeps or pulses the Safety Alert
Seat. FCA also lights an amber
visual alert if following another
vehicle much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph). If the
vehicle has Adaptive Cruise Control
(ACC), it can detect vehicles to
distances of approximately 110 m
(360 ft) and operates at all speeds.
SeeAdaptive Cruise Control on
page 9-37.
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. FCA does not warn
of pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9-3.
FCA can be disabled with the FCA
steering wheel control, or if your
vehicle is equipped with Adaptive
Cruise Control (ACC), through
vehicle personalization. See the
“Auto Collision Preparation” portion
of “Collision/Detection Systems”
under Vehicle Personalization on
page 5-47.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle-ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills; or due to poor
visibility. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
