Úpage 172.
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be driveable and not need towing,
see an authorized dealer for service as soon as possible.
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 vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have 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
Úpage 196.
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
Malfunction 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 not be ready 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.
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 do 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 position, 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 things 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 illu -
minated until you place the ignition in the off posi -
tion 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 ready, 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 previously mentioned test
routine may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system is
ready 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.
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, information
stored in your vehicle systems, including
personal information.

STARTING AND OPERATING123
The EPB switch is located on the instrument panel to the
left of the steering wheel (below the headlamp switch).

Electric Park Brake Switch

To apply the parking brake manually, pull up on the switch
momentarily. You may hear a sound from the back of the
vehicle while the parking brake 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 parking brake, you may notice a small amount of
brake pedal movement. The parking brake can be applied
even when the ignition switch is OFF but the Brake
Warning Light will not illuminate, however, it can only be
released when the ignition is in the ON/RUN position.
NOTE:The EPB Warning Light will illuminate if the EPB switch is
held for longer than 20 seconds in either the released or
applied position. The light will extinguish upon releasing
the switch. If the Auto Park Brake feature is enabled, the parking
brake will automatically engage whenever the
transmission is placed in PARK. If your foot is on the brake
pedal, you may notice a small amount of brake pedal
movement while the parking brake is engaging.
The parking brake will release automatically when the
ignition is ON, the transmission is in DRIVE or REVERSE,
the driver’s seat belt is buckled, and an attempt is made
to drive away.
To release the parking brake manually, the ignition switch
must be in the ON/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 vehicle while
the parking brake disengages. You may also notice a small
amount of movement in the brake pedal. Once the parking
brake 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
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the parking brake 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.
WARNING!

Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
 When exiting the vehicle, always turn the ignition off,
secure the key fob, and lock your vehicle.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
gear selector.
 Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter ‘n Go™ in the
ON/RUN position. A child could operate power
windows, other controls, or move the vehicle.
 Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to a 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.

124STARTING AND OPERATING
If exceptional circumstances should make it necessary to
engage the parking brake while the vehicle is in motion,
maintain upward pressure on the EPB switch for as long as
engagement is desired. The Brake Warning Light will
illuminate, and a continuous chime will sound. The rear
stop lamps will also be illuminated automatically while the
vehicle remains in motion.
To disengage the parking brake while the vehicle is in
motion, release the switch. If the vehicle is brought to a
complete stop using the parking brake, when the vehicle
reaches approximately 3 mph (5 km/h), the parking brake
will remain engaged. In the unlikely event of a malfunction of the EPB system, a
yellow EPB Warning Light will illuminate. This may be
accompanied by the Brake Warning Light flashing. In this
event, urgent service of the EPB system is required. Do not
rely on the parking brake to hold the vehicle stationary.
Auto Park Brake
The EPB can be programmed to be applied automatically
whenever the vehicle is at a standstill and the
transmission is placed in PARK. Auto Park Brake is
enabled and disabled by customer selection through the
customer programmable features section of the Uconnect
Settings
Úpage 211.
Any single Auto Park Brake application can be bypassed by
pushing the EPB switch to the release position while the
transmission is placed in PARK.
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 ON/RUN.
The parking brake will automatically engage if all of the
following conditions are met:
 The vehicle is at a standstill.
 There is no attempt to press the brake pedal or accel -
erator pedal.
 The seat belt is unbuckled.
 The driver’s door is open. SafeHold can be temporarily bypassed by pushing the EPB
switch while the driver’s door is open. Once manually
bypassed, SafeHold will be enabled again once the vehicle
reaches 12 mph (20 km/h) or the ignition is turned to the
OFF position and back to ON again.
Auto Hold — If Equipped
Auto Hold is a comfort feature that allows the driver to
remove their foot from the brake pedal once the vehicle
has come to a stop. The vehicle must be held at a
standstill for a predetermined amount of time by hydraulic
braking. The EPB will then engage and continue to hold
the vehicle at a stop until the driver applies the accelerator
pedal. Auto Hold can be activated or deactivated by
pushing the AUTO HOLD button located on the switch
bank.

AUTO HOLD Switch

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.

23_WS_OM_EN_USC_t.book Page 124

STARTING AND OPERATING125
(Continued)
The following conditions must be met for Auto Hold to
activate:

Driver’s door is closed
 Driver's seat belt is fastened
 Vehicle is at a standstill
 Forward gear is selected
 ACC is not engaged
 EPB is not applied
 ParkSense Active Park Assist System auto parking
maneuver is not activated
Brake Maintenance 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 Maintenance mode during brake
service.
When servicing your rear brakes, it may be necessary 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. Fortunately, actuator
retraction can be done easily by entering the Brake
Maintenance mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you through
the steps necessary to retract the EPB actuator in order to
perform rear brake service. Maintenance mode has requirements that must be met in
order to be activated:

The vehicle must be at a standstill.
 The parking brake must be unapplied.
 The transmission must be in PARK or NEUTRAL.
While in Maintenance mode, the EPB Warning Light will
flash continuously while the ignition is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
 Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB switch.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!
Never use the PARK (P) position as a substitute for
the parking brake. Always apply the parking brake
fully when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
 Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the trans -
mission gear selector out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before exiting the vehicle.
 The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete
stop before shifting to PARK, and verify that the
transmission gear position indicator solidly indicates
PARK without blinking. Ensure that the vehicle is
completely stopped, and the PARK position is prop -
erly indicated, before exiting the vehicle.
 It is dangerous to shift out of PARK or NEUTRAL (N) if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.

128STARTING AND OPERATING
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK (P) if you must exit
the vehicle.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears. When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), use the Electronic
Range Select (ERS) shift control to select a lower gear
Úpage 129. Under these conditions, using a lower gear
will improve performance and extend transmission life by
reducing excessive shifting and heat build-up.
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 is inhibited until the transmission fluid is
warm. Normal operation will resume once the
transmission temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically 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 certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission may
not re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions
may be necessary. In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:In cases where the instrument cluster message indicates
the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired
location (preferably, at an authorized dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if possible.
If not, shift the transmission to NEUTRAL (N).
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.

STARTING AND OPERATING129
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the highest
available gear when the transmission is in DRIVE and ERS
mode is not active. For example, if you set the
transmission gear limit to FOURTH gear, the transmission
will not shift above FOURTH gear (except to prevent engine
overspeed), but will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically,
shifting between all available gears. Tapping the “-” button
(on the steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode, tapping the “-”
or “+” button will change the top available gear.

Electronic Range Select (ERS)

To exit ERS mode, simply push and hold the “+” button
until the gear limit display disappears from the instrument
cluster.
When to Use TOW/HAUL Mode
Select TOW/HAUL mode when driving in conditions such
as: driving in hilly areas, towing a trailer, carrying a heavy
load, etc. This mode will improve performance and reduce
the potential for transmission overheating or failure due to
excessive shifting.

TOW/HAUL Switch

The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default
at engine start-up. If TOW/HAUL mode is desired, the
switch must be pushed each time the engine is started.

NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac I is a single-speed (HI range only) transfer
case, which provides convenient full-time four-wheel drive.
No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.
NOTE:The Quadra-Trac I system is not appropriate for conditions
where 4WD LOW range is recommended Úpage 193.
1 — Shift Up “+”
2 — Shift Down “–”
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.
WARNING!
Do not use the “TOW/HAUL” feature when driving in icy
or slippery conditions. The increased engine braking
can cause the rear wheels to slide, and the vehicle to
swing around with the possible loss of vehicle control,
which may cause an accident possibly resulting in
personal injury or death.

130STARTING AND OPERATING
QUADRA-TRAC II OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD HI mode. The Quadra-Trac II transfer
case provides three positions:
 4WD HI
 N (Neutral)
 4WD LOW
When additional traction is required, the 4WD LOW
position can be used for increased torque at the wheels.
Driving in the 4WD LOW position on dry, hard-surfaced
roads may cause increased tire wear and damage to
driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
SHIFT POSITIONS
For additional information on the appropriate use of each
four-wheel drive system mode position, see the following
information:
4WD HI
This range is the default operating mode for daily use.
N (NEUTRAL)
This range disengages the driveline from the powertrain. It
is used for towing your vehicle behind another vehicle
Úpage 190.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slippery
road surfaces. Do not exceed 25 mph (40 km/h).
SHIFTING PROCEDURES
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL (N), and push and
hold the 4WD LOW button once on the transfer case
switch until the 4WD LOW indicator light begins to flash in
the instrument cluster.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake should
always be applied when the driver is not in the vehicle.
WARNING!
