To Manually Turn On The Stop/Start System

Push the STOP/START OFF switch (located on the switch

bank). The light on the switch will turn off.

System Malfunction

If there is a malfunction in the STOP/START system, the

system will not shut down the engine. A “SERVICE STOP/

START SYSTEM” message will appear in the instrument

cluster display. Refer to “Instrument Cluster Display“ in

“Getting to Know Your Instrument Panel” for further

information.
If the “SERVICE STOP/START SYSTEM” message appears

STOP/START SYSTEM — MANUAL TRANSMISSION
(IF EQUIPPED)

The Stop/Start function is developed to reduce fuel con-

sumption. The system will stop the engine automatically

during a vehicle stop if the required conditions are met.

Pressing the clutch pedal will automatically restart the

vehicle.
ESS vehicles have been upgraded with a heavy duty

starter, enhanced battery, and other upgraded engine parts,

to handle the additional engine starts. Vehicles equipped

with eTorque contain a heavy duty motor generator and an

additional hybrid electric battery to store energy from

vehicle deceleration for use on engine startup after a stop

as well as providing launch torque assist.

NOTE:

It is recommended that the Start/Stop System be

disabled during off-road use.

Automatic Mode

The Stop/Start feature is enabled after every

normal customer engine start. It will remain in

STOP/START NOT READY until you drive for-

ward with a vehicle speed greater than 5 mph

(8 km/h). At that time, the system will go into STOP/

START READY and if all other conditions are met, can go

into an STOP/START AUTO STOP ACTIVE mode.

To Activate The STOP/START AUTO STOP ACTIVE
Mode, The Following Must Occur:
• The system must be in STOP/START READY state. A

STOP/START READY message will be displayed in the

instrument cluster. Refer to “Instrument Cluster Dis-

play” in “Getting To Know Your Instrument Panel” for

further information.

STARTING AND OPERATING

• Vehicle speed must be less than 2 mph (3 km/h).
• The gear selector must be in the NEUTRAL position and

the clutch pedal must be fully released

The engine will shut down, the tachometer will fall to the
Stop/Start position,

the STOP/START AUTO STOP AC-

TIVE message will appear, and the heater/air conditioning

(HVAC) air flow will be reduced.

Possible Reasons The Engine Does Not Autostop

Prior to engine shut down, the system will check many

safety and comfort conditions to see if they are fulfilled. In

following situations the engine will not stop:
• Driver’s seat belt is not buckled.
• Outside temperature is less than 10°F (–12°C) or greater

than 109°F (43°C).

may be preferable to drive without Speed Control.

WARNING!

PARKSENSE REAR PARK ASSIST — IF EQUIPPED

The ParkSense Rear Park Assist system provides visual and

audible indications of the distance between the rear fascia

and a detected obstacle when backing up, e.g. during a

parking maneuver. Refer to “ParkSense System Usage

Precautions” in this section for limitations of this system

and recommendations.
ParkSense will retain the last system state (enabled or

disabled) from the last ignition cycle when the ignition is

changed to the ON/RUN position.

332

STARTING AND OPERATING

ParkSense can be active only when the gear selector is in

REVERSE. If ParkSense is enabled at this gear selector

position, the system will remain active until the vehicle

speed is increased to approximately 7 mph (11 km/h) or

above. When in REVERSE and above the system’s operat-

ing speed, a warning will appear within the instrument

cluster display indicating the vehicle speed is too fast. The

system will become active again if the vehicle speed is

decreased to speeds less than approximately 6 mph

(9 km/h).

ParkSense Sensors

The four ParkSense sensors, located in the rear fascia/

bumper, monitor the area behind the vehicle that is within

the sensors’ field of view. The sensors can detect obstacles

from approximately 12 inches (30 cm) up to 79 inches (200

cm) from the rear fascia/bumper in the horizontal direc-

tion, depending on the location, type and orientation of the

obstacle.

ParkSense Warning Display

The ParkSense Warning screen will only be displayed if

“Sound and Display” is selected from the Customer -

Programmable Features section of the Uconnect System.

Refer to

⬙Uconnect Settings” in “Multimedia” for further

information.
The ParkSense Warning screen is located within the instru-

ment cluster display. It provides visual warnings to indi-

cate the distance between the rear fascia/bumper and the

detected obstacle. Refer to “Instrument Cluster Display” in

“Getting To Know Your Instrument Panel” for further

information.

STARTING AND OPERATING

333

ParkSense Display

When the vehicle is in REVERSE, the instrument cluster

display will show the park assist ready system status.
The system will indicate a detected obstacle by showing a

single arc in one or more regions based on the obstacle’s

distance and location relative to the vehicle.
If an obstacle is detected in the center rear region, the

display will show a single solid arc in the center rear region

and will produce a one-half second tone. As the vehicle

moves closer to the obstacle, the display will show the

single arc moving closer to the vehicle and the sound tone

will change from slow, to fast, to continuous.

If an obstacle is detected in the left and/or right rear

region, the display will show a single flashing arc in the left

and/or right rear region and will produce a fast sound

tone. As the vehicle moves closer to the obstacle, the

display will show the single arc moving closer to the

vehicle and the tone will change from fast to continuous.

Single 1/2 Second Tone/Solid Arc

Enabling And Disabling ParkSense

ParkSense can be enabled and disabled with the ParkSense

switch, located on the switch panel below the climate

controls.

When the ParkSense switch is pushed to disable the

system, the instrument cluster display will show the

“PARKSENSE OFF” message for approximately five sec-

onds. Refer to “Instrument Cluster Display” in “Getting To

Know Your Instrument Panel” for further information.

When the gear selector is moved to REVERSE and the

system is disabled, the instrument cluster display will

show the “PARKSENSE OFF” message for as long as the

vehicle is in REVERSE.
The ParkSense switch LED will be on when ParkSense is

disabled or requires service. The ParkSense switch LED

will be off when the system is enabled. If the ParkSense

switch is pushed, and requires service, the ParkSense

switch LED will blink momentarily, and then the LED will

be on.

Service The ParkSense Rear Park Assist System

During vehicle start up, when the ParkSense Rear Park

Assist System has detected a faulted condition, the instru-

ment cluster display will actuate a single chime, once per

ignition cycle, and it will display the “PARKSENSE UN-

AVAILABLE WIPE REAR SENSORS” or the “PARKSENSE

UNAVAILABLE SERVICE REQUIRED” message. Refer to

“Instrument Cluster Display”. When the gear selector is

moved to REVERSE and the system has detected a faulted

condition, the instrument cluster display will show the

⬙PARKSENSE UNAVAILABLE WIPE REAR SENSORS⬙ or

⬙PARKSENSE UNAVAILABLE SERVICE REQUIRED⬙ mes-

sage for as long as the vehicle is in REVERSE. Under this

condition, ParkSense will not operate.

ParkSense Switch

338

STARTING AND OPERATING

If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”

appears in the instrument cluster display, make sure the

outer surface and the underside of the rear fascia/bumper

is clean and clear of snow, ice, mud, dirt or other obstruc-

tion and then cycle the ignition. If the message continues to

appear, see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”

appears in the instrument cluster display, see an autho-

rized dealer.

Cleaning The ParkSense System

Clean the Rear Park Assist sensors with water, car wash

soap and a soft cloth. Do not use rough or hard cloths. In

washing stations, clean sensors quickly keeping the vapor

jet/high pressure washing nozzles at least 4 inches (10 cm)

from the sensors. Do not scratch or poke the sensors.

Otherwise, you could damage the sensors.

ParkSense System Usage Precautions

NOTE:
• Ensure that the rear bumper is free of snow, ice, mud,

dirt and debris to keep the ParkSense system operating

properly.

• Jackhammers, large trucks, and other vibrations could

affect the performance of ParkSense.

• When you turn ParkSense OFF, the instrument cluster

display will read “PARKSENSE OFF” Furthermore, once

you turn ParkSense OFF, it remains off until you turn it

on again, even if you cycle the ignition.

• ParkSense, when on, will reduce the volume of the radio

when it is sounding a tone.

• Clean the ParkSense sensors regularly, taking care not to

scratch or damage them. The sensors must not be

covered with ice, snow, slush, mud, dirt or debris.

Failure to do so can result in the system not working

properly. The ParkSense system might not detect an

obstacle behind the fascia/bumper, or it could provide a

false indication that an obstacle is behind the fascia/

bumper.

STARTING AND OPERATING

339

• Use the ParkSense switch to turn the ParkSense system

OFF if objects such as bicycle carriers, trailer hitches, etc.

are placed within 12 inches (30 cm) from the rear

fascia/bumper. Failure to do so can result in the system

misinterpreting a close object as a sensor problem,

causing the “PARKSENSE UNAVAILABLE SERVICE

REQUIRED” message to be displayed in the instrument

cluster display.

• The operation of the rear sensors is automatically deac-

tivated when the trailer’s electric plug is inserted in the

vehicle’s tow hook socket. The rear sensors are automati-

cally reactivated when the trailer’s cable plug is re-

moved.

WARNING!

• Drivers must be careful when backing up even when

using ParkSense. Always check carefully behind
your vehicle, look behind you, and be sure to check
for pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon-
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.

(Continued)

WARNING! (Continued)

• Before using ParkSense, it is strongly recommended

that the ball mount and hitch ball assembly is discon-
nected from the vehicle when the vehicle is not used
for towing. Failure to do so can result in injury or
damage to vehicles or obstacles because the hitch ball
will be much closer to the obstacle than the rear fascia
when the loudspeaker sounds the continuous tone.
Also, the sensors could detect the ball mount and hitch
ball assembly, depending on its size and shape, giving
a false indication that an obstacle is behind the vehicle.

CAUTION!

• ParkSense is only a parking aid and it is unable to

recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.

• The vehicle must be driven slowly when using

ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.

STARTING AND OPERATING

PARKVIEW REAR BACK UP CAMERA

The ParkView Rear Back Up Camera allows you to see an

on-screen image of the rear surroundings of your vehicle

whenever the gear selector is put into REVERSE. The

image will be displayed in the touchscreen display along

with a caution note to “check entire surroundings” across

the top of the screen. After five seconds this note will

disappear. The ParkView camera is located on the rear of

the vehicle in the center of the spare tire.

NOTE:

The ParkView Rear Back Up Camera has program-

mable modes of operation that may be selected through the

Uconnect System. Refer to “Uconnect Settings” in “Multi-

media” for further information.
When the vehicle is shifted out of REVERSE (with camera

delay turned off), the rear camera mode is exited and the

previous screen appears again. When the vehicle is shifted

out of REVERSE (with camera delay turned on), the camera

image will continue to be displayed for up to ten seconds

after shifting out of REVERSE unless the vehicle speed

exceeds 8 mph (13 km/h), the vehicle is shifted into PARK

or the vehicle’s ignition is cycled to the OFF position.
When enabled, active guide lines are overlaid on the image

to illustrate the width of the vehicle and its projected

backup path based on the steering wheel position. A

dashed center line overlay indicates the center of the

vehicle to assist with parking or aligning to a hitch/

receiver.
When enabled, fixed guide lines are overlaid on the image

to illustrate the width of the vehicle.
