STARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.

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 an authorized dealer) is recommended.
Extended Park Starting

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. Place the ignition to the START mode and release it when the engine starts.
3. If the engine fails to start within 10 seconds, place the ignition in the OFF mode, wait five seconds to allow the
starter to cool, then repeat the Extended Park Starting

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 ’s
side 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 an 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.

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 park
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. The
parking brake should always be applied whenever the
driver is not in the vehicle.

switch for as long as engagement is desired. The BRAKE
telltale light will illuminate, and a continuous chime will
sound. The rear stop lamps will also be illuminated auto-
matically while the vehicle remains in motion.
To disengage the park 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.

SafeHold can be temporarily bypassed by pushing the
Electric Park Brake Switch while the driver 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.
Brake Service Mode
We recommend having your brakes serviced by your
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Service Mode during brake ser-
vice.
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 electric park brake system, this can
only be done after retracting the Electric Park Brake
actuator. Fortunately, actuator retraction can be done easily
by entering the Brake Service 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.Service Mode has requirements that must be met in order
to be activated:
•
The vehicle must be at a standstill.
• The park brake must be unapplied.
• The transmission must be in PARK or NEUTRAL.
While in service mode, the Electric Park Brake fault lamp
will flash continuously while the ignition is ON.
When brake service work is complete, the following steps
must be followed to reset the park brake system to normal
operation:
• Ensure the vehicle is at a standstill.
• Press the brake pedal with moderate force.
• Apply the Electric Park Brake Switch.
