by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn signal
and high beam indicator lights on the instrument panel.

258 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle. If equipped
with Keyless Enter-N-Go, always make sure the
keyless ignition node is in “OFF” mode, remove the
key fob from the vehicle and lock the 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 seriously 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 the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle. Start the engine with the gear selector in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting — Gasoline Engine
NOTE:
Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
Cycle the ignition to the START mode and release when the
engine starts. If the engine fails to start within 10 seconds,
cycle the ignition to the LOCK/OFF mode, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
Tip Start Feature
Cycle the ignition to START mode and release it as the
starter engages. The starter motor will automatically dis-
engage itself once engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, cycle the ignition to the OFF mode,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.

STARTING AND OPERATING 261

Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
Extended Park Starting
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the crank cycle.
2. Cycle the ignition in the START position and release it when the engine starts.
3. If the engine fails to start within 10 seconds, cycle the ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat the
procedure.
CAUTION!
To prevent damage to the starter, do not crank continu-
ously for more than 10 seconds at a time. Wait 10 to 15
seconds before trying again.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.
•If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery or
the battery in another vehicle. This type of start can be
dangerous if done improperly. Refer to “Jump-Starting”
in “In Case Of Emergency” for further information.
262 STARTING AND OPERATING

After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and permits
quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical outlet with
a grounded, three-wire extension cord.
For ambient temperatures below 0°F (-18°C), the engine
block heater is recommended. For ambient temperatures
below -20°F (-29°C), the engine block heater is required.
The engine block heater cord is routed under the hood,
behind to the driver ’s side headlamp. Follow the steps
below to properly use the engine block heater:
1. Locate the engine block heater cord (behind the driver ’sside headlamp).
2. Undo the Velcro strap that secures the heater cord in place.
3. Pull the cord to the front of the vehicle and plug it into a grounded, three-wire extension cord. 4. After the vehicle is running, reattach the cord to the
Velcro strap and properly stow away behind the driver ’s
side headlamp.
NOTE:
• The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer.
• The engine block heater will require 110 Volts AC and 6.5
Amps to activate the heater element.
• The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.

STARTING AND OPERATING 263

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 detri-
mental 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 recom-
mended viscosity and quality grades, refer to “Dealer
Service” in “Servicing And Maintenance”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.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
interpreted as a problem.
PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park Brake
System (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 park brake is applied. Also, be
certain to leave the transmission in PARK.
You can engage the park brake in two ways:
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature
in the customer programmable features section of the
Uconnect settings.
264 STARTING AND OPERATING

AUTOMATIC TRANSMISSION
WARNING!
•It is dangerous to shift out of PARK or NEUTRAL 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 re-
verse. 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.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the key fob. When
the ignition is in the LOCK/OFF (key removal)
position, (or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
(Continued)
WARNING! (Continued)
•When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the vehicle.
• 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.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before leav-
ing the 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 seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.
