154STARTING AND OPERATING
PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and
the front fascia/bumper and a detected obstacle when
backing up or moving forward (e.g. during a parking
maneuver). The vehicle brakes may be automatically
applied and released when performing a reverse parking
maneuver if the system detects a possible collision with
an obstacle.
NOTE:
The driver can disable the automatic braking function
by turning ParkSense off via the ParkSense switch. The
driver can also override automatic braking by changing
the gear or by pressing the gas pedal over 90% of its
capacity during the braking event.
 Automatic brakes are not available if the vehicle is in
4WD Low.
 Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
 The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
 The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
 The automatic braking function can be enabled/
disabled from the Customer Programmable Features
section of the Uconnect system. 
ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected
obstacles when backing up in REVERSE gear.
NOTE:
 The system is designed to assist the driver and not to
substitute the driver.
 The driver must stay in full control of the vehicle's
acceleration and braking and is responsible for the
vehicle's movements.
For limitations of this system and recommendations, see
Úpage 159.
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.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of
these gear selector positions, the system will remain
active until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above. The system will
become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h). A display
warning will appear in the instrument cluster display if the
vehicle is in REVERSE and the speed exceeds 7 mph
(11 km/h).
PARKSENSE SENSORS
The four ParkSense sensors located in the rear fascia/
bumper, and the six ParkSense sensors located in the
front fascia/bumper, monitor the area in front and behind
the vehicle that is within the sensors’ field of view. The
front sensors detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from the front fascia/bumper. The rear sensors can detect obstacles
from approximately 12 inches (30 cm) up to 79 inches
(200 cm) from the rear fascia/bumper. These distances
depend on the location, type and orientation of the
obstacle in the horizontal direction.
NOTE:If the vehicle is equipped with ParkSense Active Park
Assist, there will be six ParkSense sensors located in the
rear fascia/bumper.
PARKSENSE DISPLAY
The warning display will turn on indicating the system
status when the vehicle is in REVERSE or when the vehicle
is in DRIVE and an obstacle has been detected.
The system will indicate a detected obstacle by showing a
single arc in the left and/or right front or rear regions
based on the object’s distance and location relative to the
vehicle.
If an object is detected in the left and/or right rear region,
the display will show a single arc in the left and/or right
rear region and the system will produce a tone. As the
vehicle moves closer to the object, the display will show
the single arc moving closer to the vehicle and the tone will
change from a single 1/2 second tone to slow, to fast, to
continuous.

266SAFETY
Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors (if equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions. This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is buckled. The seat
belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle is equipped with a right front passenger
Occupant Classification System (“OCS”) that is designed
to provide Passenger Advanced Front Air Bag output
appropriate to the occupant’s seated weight input, as
determined by the OCS.
Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front air bags
are not expected to reduce the risk of injury in rear, side,
or rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce
substantial vehicle damage — for example, some pole
collisions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC) detects a
collision requiring the front air bags, it signals the inflator
units. A large quantity of non-toxic gas is generated to
inflate the front air bags.
The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate and fold
out of the way as the air bags inflate to their full size. The
front air bags fully inflate in less time than it takes to blink
your eyes. The front air bags then quickly deflate while
helping to restrain the driver and front passenger.WARNING!

Being too close to the steering wheel or instrument
panel during front air bag deployment could cause
serious injury, including death. Air bags need room to
inflate. Sit back, comfortably extending your arms to
reach the steering wheel or instrument panel.
 Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
 Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.
WARNING!
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
 Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
 Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some colli -
sions, air bags won’t deploy at all. Always wear your
seat belts even though you have air bags.

328SERVICING AND MAINTENANCE
(Continued)
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine off and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator/coolant pressure cap
unless checking for engine coolant freeze point or
replacing coolant. Advise your service attendant of this. As
long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant is needed to maintain the
proper level, only OAT coolant that meets the
requirements of the manufacturer Material Standard
MS.90032 should be added to the coolant bottle. Do not
overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilometers
of operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to enter
the radiator. If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.

Do not overfill the coolant expansion bottle.
 Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant needs
to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
 If frequent engine coolant additions are required, the
cooling system should be pressure tested for leaks.
 Maintain engine coolant concentration at a minimum
of 50% OAT coolant (conforming to MS.90032) and
distilled water for proper corrosion protection of your
engine which contains aluminum components.
 Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
 Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
 Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically. For
the proper maintenance intervals
Úpage 310.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
Brake System Warning Light is on. If necessary, add fluid
to bring level within the designated marks on the side of
the reservoir of the brake master cylinder. Be sure to clean
the top of the master cylinder area before removing cap.
With disc brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be checked
when pads are replaced. If the brake fluid is abnormally
low, check the system for leaks.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on the
brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
WARNING!
Use only manufacturer's recommended brake fluid Úpage 377. Using the wrong type of brake fluid can
severely damage your brake system and/or impair its
performance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
