Driving and Operating 185
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 that 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
the driver 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 might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the vehicle
is off.
The system has a red parking brake
status light and an amber parking
brake warning light. SeeElectric
Parking Brake Light 0111 and
Service Electric Parking Brake Light
0 111. There are also parking
brake-related Driver Information
Center (DIC) messages. See Brake
System Messages 0130. 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. Pull the EPB switch momentarily.

stationary. If HSA is holding the
vehicle, a DIC message displays.
HSA will not activate in a forward
drive gear when facing downhill,
or in R (Reverse) when facing uphill.
Extended Hill Start
Assist (EHSA)
Select the duration of the HSA
feature on the center stack
touchscreen by choosing the
submenu for Hill Start Assist or
Extended Hill Start Assist (EHSA).
See“Extended Hill Start Assist"
under “Comfort and Convenience” in
Vehicle Personalization 0138.
When Standard Hold is selected,
the vehicle is held stationary for up
to two seconds after the brake pedal
is released. When Extended Hold is
selected, the vehicle is held
stationary for up to five minutes
after the brake pedal is released. In
either case, override the hold
feature by pressing the accelerator
pedal and attempting to drive away.
If Hill Start Assist is selected in the
Settings menu, it will hold the
vehicle for two seconds unless the
driver door is opened or the driver safety belt is unbuckled after
releasing the brake pedal.
If Extended Hill Start Assist is
selected, it will hold the vehicle for
five minutes unless the driver door
is opened and the driver safety belt
is unbuckled prior to releasing the
brake pedal. When EHSA is
deactivated after five minutes, or if it
is deactivated when the driver
safety belt is unlatched or the driver
door is opened, the Electric Parking
Brake will engage to prevent vehicle
movement.
Regenerative Braking
Some braking energy from the
moving vehicle is turned back into
electrical energy. This energy is
then stored back into the high
voltage battery system, increasing
energy efficiency.
The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The controller interprets the braking
request and uses regenerative
braking, conventional hydraulic
braking, or a combination of both as
necessary.
The brake controller applies the
hydraulic brakes using a pump. The
pump may be heard during some
braking, such as rapid applies. This
is normal.
See
Warning Lights, Gauges, and
Indicators 0100 andDriver
Information Center (DIC) 0128.
If there is a controller problem, the
brake pedal may be harder to push
and the stopping distance may be
longer.

Regen on Demand®
Regen on Demand allows increased
deceleration by pressing and
holding the steering wheel paddle.
It works in D (Drive) and L (Low).
The accelerator pedal must be fully
released for it to work.The brake pedal must be applied at
low speed, because Regen on
Demand will not bring the car to a
full stop.
Cruise control will turn off, and the
brake lights may come on, when
this feature is activated.
The brake controller applies the
hydraulic brakes using a pump. You
may hear the pump during some
braking maneuvers, such as rapid
brake applies or while replacing any
regenerative brake torque as the
vehicle comes to a stop. This is
normal operation.
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and an Electronic
Stability Control system called
StabiliTrak. These systems help
limit wheel slip and assist the driver
in maintaining control, especially on
slippery road conditions.
TCS activates if it senses that any
of the drive wheels are slipping 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 activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any of the
vehicle wheel brakes to help assist
the driver in keeping the vehicle on
the intended path.

When road conditions allow you to
safely use it again, cruise control
can be turned back on.
If the brakes are applied, cruise
control disengages.
5: Press to turn the cruise control
system on and off. A white indicator
comes on in the instrument cluster
when cruise is turned on.
*: Press to disengage cruise
control without erasing the set
speed from memory.
+RES : If there is a set speed in
memory, press briefly to resume that
speed or press and hold to
accelerate. If cruise control is
already active, use to increase
vehicle speed.
−SET : Press briefly to set the
speed and activate cruise control.
If cruise control is already active,
use to decrease vehicle speed.
Setting Cruise Control
If
5is on when not in use, -SET or
+RES could get bumped and go into
cruise when not desired. Keep
5
off when cruise is not being used.
To set a speed:
1. Press
5to turn the cruise
system on.
2. Get up to the desired speed.
3. Press and release -SET. The desired set speed briefly
appears in the instrument
cluster. 4. Remove foot from the
accelerator pedal.
The cruise control indicator on the
instrument cluster turns green after
cruise control has been set to the
desired speed. See Instrument
Cluster 0100.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied or
*is pressed, the
cruise control is disengaged without
erasing the set speed from memory.
Once the vehicle speed reaches
about 40 km/h (25 mph) or more,
briefly press +RES. The vehicle
returns to the previous set speed.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Press and hold +RES on the
steering wheel until the vehicle
accelerates to the desired
speed, then release it.

.To increase the speed in small
increments, briefly press +RES.
For each press, the vehicle goes
about 1 km/h (1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units. See Driver Information Center
(DIC) 0128. The increment value
used depends on the units
displayed.
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Press and hold -SET until the
desired lower speed is reached,
then release it.
. To slow down in small
increments, briefly press -SET.
For each press, the vehicle goes
about 1 km/h (1 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Driver Information Center
(DIC) 0128. The increment value
used depends on the units
displayed. Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previous set cruise speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
pressing -SET will result in cruise
control set to the current vehicle
speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep your
speed down.
If a lower gear is being used while
going downhill, this causes the
vehicle to have improved control of
vehicle speed by using a
combination of engine andregenerative braking depending on
vehicle conditions. At times you
might have to apply the brakes to
keep your speed down. If the brake
pedal is applied, cruise control will
disengage.
Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal;
when cruise control disengages,
the indicator light will not be lit.
. Press
*.
. Shift the electric drive unit to
N (Neutral).
. Press
5to turn the cruise
control system off completely.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
5is pressed
or if the vehicle is turned off.

Automatic Parking
Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears,
and control the brakes and
accelerator. The Driver Information
Center (DIC) and audible beeps
help to guide parking maneuvers.
{Warning
APA does not apply the brakes.
APA may not detect objects in the
parking space, objects that are

Warning (Continued)
soft or narrow, objects high off the
ground such as flatbed trucks,
or objects below ground level
such as large potholes. Always
verify that the parking space is
appropriate for parking a vehicle.
APA does not respond to changes
in the parking space, such as
movement of an adjacent vehicle,
or a person or object entering the
parking space. APA does not
detect or avoid traffic that is
behind or alongside of the
vehicle. Always be prepared to
stop the vehicle during the
parking maneuver.
The system is available when the
vehicle speed is below
30 km/h (18 mph). Press

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 vehicle
into 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:
.
