OPERATING TIPS
Refer to the chart at the end of this section for suggested
control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling system is
functioning properly and the proper amount, type, and
concentration of coolant is used. Use of the Air
Recirculation mode during Winter months is not
recommended, because it may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control system
when the vehicle is being stored for an extended period of
time, see
Úpage 387.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower speed.
Do not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions, such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the air distribution box, they could plug the water
drains. In Winter months, make sure the air intake is clear
of ice, slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and pollen
from the air. Contact an authorized dealer to service your
cabin air filter, and to have it replaced when needed.

122STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the
recommended viscosity and quality grades
Úpage 396.
NOTE:A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter -
preted as a problem. Please check your oil level with the
engine oil indicator often during the break-in period. Add
oil as required.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers simple
operation, and some additional features that make the
parking brake more convenient and useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the
vehicle, make sure that the parking brake is applied. Also,
be certain to leave the transmission in PARK.
You can engage the parking brake in two ways:
 Manually, by applying the parking brake switch.
 Automatically, by enabling the Auto Park Brake feature
in the Customer Programmable Features section of the
Uconnect settings.
The parking brake 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 slight sound from the back
of the vehicle while the parking brake engages. Once the
park brake is fully engaged, the BRAKE telltale 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
telltale 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 into 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 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 parking brake switch down
momentarily. You may hear a slight whirring sound from
the back of the vehicle while the parking brake
disengages.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

142STARTING AND OPERATING
To Activate The Autostop Mode, The Following Must Occur:

1. The system must be in STOP/START READY state. A
STOP/START READY message is displayed in the
instrument cluster within the Stop/Start section

Ú
page 98.

2. The vehicle must be decelerating and likely coming to a complete stop.
3. The transmission gear selector must be in DRIVE and the brake pedal pressed.
The engine will shut down, the tachometer will move to the
zero position and the Stop/Start telltale will illuminate
indicating you are in an Autostop. While in an Autostop,
the Climate Controls system may automatically adjust
airflow to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT 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 Autostop:
 Driver’s seat belt is not buckled
 Driver’s door is not closed
 The vehicle is on a steep grade
 Cabin heating or cooling is in process and an accept -
able cabin temperature has not been achieved 
HVAC is set to full defrost mode at a high blower speed
 Engine has not reached normal operating temperature
 Engine or exhaust temperature is too high
 The battery is charging
 The transmission is not in DRIVE
 Hood is open
 Transfer case is in 4WD LOW
 TOW/HAUL mode is selected
 Accelerator pedal input
 Excessive 12 Volt loads
 Brake application is adequate to obtain and maintain
a stop
It may be possible to operate the vehicle several
consecutive times in extreme conditions and not meet all
criteria to enable an Autostop state.TO START THE ENGINE WHILE IN
A
UTOSTOP MODE
While in DRIVE, the engine will start when the brake pedal
is released or the accelerator pedal is pressed and the
transmission will automatically reengage upon engine
restart. Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode
The engine will start automatically when:

The transmission selector is moved from DRIVE to
REVERSE, NEUTRAL, or PARK
 To maintain cabin temperature near the HVAC settings
 HVAC is set to full defrost mode
 12 Volt demand requires engine restart
 Stop/Start OFF switch is pushed
 Transfer case is in 4WD LOW
 The emissions system override is present
 A Stop/Start system error is present
Conditions That Force An Automatic Shift To Park While In
Autostop Mode
The engine will not start automatically and the
transmission will be placed in PARK if:
 The driver door is open and brake pedal released
 The driver door is open and the driver seat belt is
unbuckled
 The engine hood has been opened
 A Stop/Start system error is present
The engine may then be restarted by moving the
transmission shift selector out of PARK (e.g., to DRIVE) or,
in some cases, only by a key start. The instrument cluster
will display a “SHIFT OUT OF PARK” message, or a
“STOP/START KEY START REQUIRED” message, to
indicate which action is required
