78 GETTING TO KNOW YOUR INSTRUMENT PANEL
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may need
to access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú page 133.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies
the Ma

lfunction Indicator Light (MIL) is
functioning and is not on when the
engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The
OBD II system may n
ot be r
eady if your vehicle was
recently serviced, recently had a depleted battery
or a battery replacement. If the OBD II system
should be determined not ready for the I/M test,
your vehicle may fail the test.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing, while the engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection
port in order to read the VIN, diagnose, or
service your vehicle.
If unauthorized equipment is connected to the
OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
inclu d
ing personal information.

GETTING TO KNOW YOUR INSTRUMENT PANEL 79
Your vehicle has a simple ignition actuated test,
which you can use prior to going to the test station.
To check if your vehicle's OBD II system is ready,
you must do the following:

1. Cycle the ignition switch to the ON position,
but d
o not crank or start the engine.

NOTE:
If you crank or start the engine, you will have to
start
this test over.
2. As soon as you cycle the ignition switch to the ON pos
ition, you will see the Malfunction
Indicator Light (MIL) symbol come on as part of
a normal bulb check. 3. Approximately 15 seconds later, one of two
thing

s will happen:
The MIL will flash for about 10 seconds and
then return to being fully illuminated until
you turn OFF the ignition or start the engine.
This means that your vehicle's OBD II
system is not ready and you should not
proceed to the I/M station.
The MIL will not flash at all and will remain
fully illuminated until you place the ignition
in the off position or start the engine. This
means that your vehicle's OBD II system is
ready and you can proceed to the I/M
station. If your OBD II system is
not rea
dy, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do nothing
more than drive your vehicle as you normally would
in order for your OBD II system to update. A
recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
is re a

dy or not, if the MIL is illuminated during
normal vehicle operation you should have your
vehicle serviced before going to the I/M station.
The I/M station can fail your vehicle because the
MIL is on with the engine running.3

STARTING AND OPERATING 83

Electric Park Brake Switch

To apply the EPB manually, pull up on the switch
momenta
rily. You may hear a sound from the back
of the vehicle while the EPB engages. Once the
parking brake is fully engaged, the Brake Warning
Light in the instrument cluster and an indicator on
the switch will illuminate. If your foot is on the
brake pedal while you apply the EPB, you may
notice a small amount of brake pedal movement.
The EPB can be applied even when the ignition is
in the OFF position however, it can only be released
when the ignition is in the RUN position.
NOTE:
The EPB fault lamp will illuminate if the EPB switch
is he l
d for longer than 60 seconds in either the
released or applied position. The light will extin -
guish upon releasing the switch.
If the Auto Park Brake feature is enabled, the EPB
w ill a

utomatically engage whenever the
transmission is moved into PARK when the ignition switch is in the STOP/OFF position. If your foot is on
the brake pedal, you may notice a small amount of
brake pedal movement while the EPB is engaging.
The EPB will be automatically released if the
drive
r

's seat belt is buckled (only in case of
automatic transmission) and driver's intention to
start (in forward or reverse direction) is recognized
by the system.
To release the EPB manually, the ignition must be
in th e

RUN position. Put your foot on the brake
pedal, then push the EPB switch down
momentarily. You may hear a sound from the back
of the car while the parking brake disengages. You
may also notice a small amount of movement in
the brake pedal. Once the EPB is fully disengaged,
the Brake Warning Light in the instrument cluster
and the LED indicator on the switch will extinguish.
NOTE:
When parking on a hill, it is important to turn the
front w
heels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the EPB before placing the gear selector in PARK,
otherwise the load on the transmission locking
mechanism may make it difficult to move the gear
selector out of PARK. The EPB should always be
applied whenever the driver is not in the vehicle.
WARNING!
When exiting the vehicle, always remove the
key fob from the vehicle and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
d anger

ous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ON or RUN posi -
tion. A child could operate power windows,
other c

ontrols, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave the
transmission in PARK. Failure to do so may
allow the vehicle to roll and cause damage or
injury.

84 STARTING AND OPERATING
If exceptional circumstances should make it
necessary to engage the EPB while the vehicle is in
motion, maintain upward pressure on the EPB
switch for as long as engagement is desired. The
Brake Warning Light could illuminate in case the
hydraulic system is not available. The rear stop
lamps will also be illuminated automatically while
the vehicle remains in motion.
To disengage the EPB while the vehicle is in
motion,

release the switch. If the vehicle is brought
to a complete stop using the EPB, when the vehicle
reaches approximately 1.9 mph (3 km/h) the EPB
will r

emain engaged. In the unlikely event of a malfunction of the EPB
syste
m

, a yellow EPB fault lamp will illuminate. This
may be accompanied by the Brake Warning Light
flashing. In this status, some EPB functionalities
may be deactivated. In this event, urgent service of
the EPB system is required. Do not rely on the EPB
to hold the vehicle stationary.
AUTO PARK BRAKE
The EPB can be programmed to be applied
automatically whenever the vehicle speed is below
1.9 mph (3 km/h) and the automatic transmission
is pla

ced in PARK whenever the ignition is in the
OFF position. Auto Park Brake is enabled and
disabled by customer selection through the
Customer Programmable Features section of the
Uconnect Settings.
Any single Auto Park Brake application can be
bypas s

ed by pushing the EPB switch to the release
position while the transmission is placed in PARK
and the ignition is in the RUN position. In some
cases, if the ignition is cycled from ON/RUN to OFF
and the gear selector is not firmly locked in the
PARK position, EPB applies automatically even if
Auto Park Brake has been previously disabled.
SAFEHOLD
SafeHold is a safety feature of the EPB system that
will engage the parking brake automatically if the
vehicle is left unsecured while the ignition is in the
RUN position. The EPB will automatically engage if all of the
followi
n

g conditions are met:
Vehicle speed is below 1.9 mph (3 km/h).
There is no attempt to press the brake pedal or
accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
The vehicle is not in the PARK position.
SafeHold can be temporarily bypassed by pushing
the E P

B Switch while the driver door is open and
the brake pedal is pressed. Once manually
bypassed, SafeHold will be enabled again once the
vehicle reaches 12 mph (20 km/h) or the ignition
is pla

ced to the OFF position and back to RUN
again.
BRAKE SERVICE MODE
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake Service
Mode during brake service.
When servicing your rear brakes, it may be
neces s

ary for you or your technician to push the
rear piston into the rear caliper bore. With the EPB
system, this can only be done after retracting the
EPB actuator. The actuator retraction can be done
easily by entering the Brake Service Mode. This
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking brake
to slow the vehicle may cause serious damage to
the brake system. Be sure the parking brake is
fully disengaged before driving; failure to do so
can lead to brake failure and a collision.

STARTING AND OPERATING 89
these conditions, using a lower gear will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal
operat i

ng limits, the transmission controller may
modify the transmission shift schedule, reduce
engine torque, and/or expand the range of torque
converter clutch engagement. This is done to
prevent transmission damage due to overheating.
If the transmission becomes extremely hot, the
Trans m

ission Temperature Warning Light may
illuminate and the transmission may operate
differently until the transmission cools down.
During cold temperatures, transmission operation
may be
modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch, and shifts into EIGHTH or NINTH gear, are
inhibited until the transmission fluid is warm.
Normal operation will resume once the
transmission temperature has risen to a suitable
level.
AutoStick
AutoStick is a driver-interactive transmission
f eatu r

e providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall vehicle performance. This system can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing and many other situations.
Operation
When the gear selector is in the AutoStick position
(besi
d

e the DRIVE position), it can be moved
forward and rearward. This allows the driver to
manually select the transmission gear being used.
Moving the gear selector forward (-) triggers a
downshift, and rearward (+) an upshift. The current
gear is displayed in the instrument cluster.
NOTE:
In AutoStick mode, the transmission will only shift
up or d
own when the driver moves the gear
selector rearward (+) or forward (-), except as
described below:
The transmission will automatically upshift
when necessary to prevent engine overspeed.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST or SECOND gear (depending on model)
when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as
the vehicle is accelerated.
You can start out (from a stop) in FIRST or
SECOND gear. Starting out in SECOND gear can
be helpful in snow or icy conditions. Tap the gear
selector forward or rearward to select the
desired gear after the vehicle is brought to a
stop.
If a requested downshift would cause the
engine to overspeed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Avoid using Cruise Control when AutoStick is
engaged because the transmission will not shift
automatically.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
To disengage AutoStick mode, return the gear
select
or to the DRIVE position. You can shift in or
out of the AutoStick position at any time without
taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

90 STARTING AND OPERATING
TRANSMISSION LIMP HOME MODE
Transmission function is electronically monitored
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in a fixed
gear, or may remain in neutral. The Malfunction
Indicator Light (MIL) may be illuminated. Limp
Home Mode may allow the vehicle to be driven to
an authorized dealer for service without damaging
the transmission.
In the event of a momentary problem, the
trans m

ission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. S hif

t the transmission into PARK, if possible. If
n ot
,
s

hift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engin
e turns off.
4. Wait approximately 30 seconds.
5. Res
tart the engine.
6. S hif

t into the desired gear range. If the
p r
ob l
e

m is no longer detected, the
transmission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recomm e
nd that you visit an authorized dealer at your earliest possible convenience. An authorized
dealer has diagnostic equipment to determine if
the problem could recur. If the transmission
cannot be reset, authorized dealer service is
required.
IGNITION PARK INTERLOCK
(K
EYLESS VEHICLE)
This vehicle is equipped with an Ignition Park
Interlock, which requires the transmission to be in
PARK before the ignition can be turned to the OFF
position. Also, the transmission is locked in PARK
whenever the ignition is in the OFF position.
BRAKE TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK unless the
brakes are applied. To shift the transmission out of
PARK, the ignition must be in the RUN position
(engine running or not) and the brake pedal must
be pressed.
The brake pedal must also be pressed before
pushi n

g the button on the gear selector to shift
from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds.
FOUR-WHEEL DRIVE
Active Drive (4WD) And Active Drive Low (4WD
LOW)
Your vehicle may be equipped with a Power
Transf
er Unit (PTU). This system is automatic with
no driver inputs or additional driving skills
required. Under normal driving conditions, the
front wheels provide most of the traction. If the
front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the
front wheel traction loss, the greater the power
transfer to the rear wheels.
Additionally, on dry pavement under heavy throttle
input

(where one may have no wheel spin), torque
will be sent to the rear in a preemptive effort to
improve vehicle launch and performance
characteristics.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the power
transfer unit.

STARTING AND OPERATING 91
FOUR-WHEEL DRIVE (4WD)

If the “SERVICE STOP/START SYSTEM” message
appea r

s in the instrument cluster display, have the
system checked by an authorized dealer.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control for cruising at a constant preset
speed.
Adaptive Cruise Control (ACC) for maintaining a
set distance between you and the vehicle ahead
using Fixed Speed Cruise Control to automati -
cally adjust the preset speed.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20
mph (32 km/h).
The Cruise Control buttons are located on the right
side of

the steering wheel.

Accelerating For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hi
lls. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.
WARNING!
Leaving the Cruise Control system on when not
in use is dangerous. You could accidentally set
the system or cause it to go faster than you
want. You could lose control and have an
accident. Always leave the system OFF when you
are not using it.
WARNING!
Cruise Control can be dangerous where the

ments until the button is released. The new set
s peed

is reflected in the instrument cluster
display.
NOTE:
When you override and push the SET (+) bu t ton or
SET (-) button, the new set speed will be the current
speed of the vehicle. When ACC Is Active:
When you use the SET
(-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting will show in the instrument cluster display.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.
