Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may
not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a TPMS that illuminates a
low tire pressure telltale when one or more of
your tires is significantly underinflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the
malfunction indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair
kit and contact an authorized dealer as soon
as possible.

Vehicle Security Warning Light
This warning light will illuminate when
the vehicle security system has
detected an attempt to break into the
vehicle.
Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction
Indicator Light (MIL) is a part of an
Onboard Diagnostic System called
OBD II that monitors engine and
automatic transmission control systems. This
warning light will illuminate when the ignition is in
the ON/RUN position before engine start. After
placing the ignition to the ON/RUN position, if
there is a problem with the Sentry Key System,
the Vehicle Security Light will turn on. This
condition will result in the engine being shut off
after two seconds. If the bulb does not come on
when turning the ignition switch from OFF to ON/
RUN, have the condition checked promptly.
NOTE:
This warning light will illuminate when the
vehicle security system has detected an
attempt to break into the vehicle.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illuminate the
light after engine start. The vehicle should be
serviced if the light stays on through several
typical driving styles. In most situations, the
vehicle will drive normally and will not require
towing. When the engine is running, the MIL may flash
to alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be
serviced by an authorized dealer as soon as
possible if this occurs.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the
tire size equipped on your vehicle.
Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type,
and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized dealer to have your
sensor function checked.
WARNING!
A malfunctioning catalytic converter, as refer
-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over
flammable substances such as dry plants,
wood, cardboard, etc. This could result in
death or serious injury to the driver, occu -
pants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause damage
to the vehicle control system. It also could
affect fuel economy and driveability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur.
Immediate service is required.

Electronic Stability Control (ESC) Warning
Light — If Equipped
The ESC Indicator Light in the
instrument cluster will come on when
the ignition is placed in the ON/RUN
or MAR/ON/RUN position, and when
ESC is activated. It should go out with the
engine running. If the ESC Indicator Light comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
The ESC OFF Indicator Light and the ESC Indi -
cator Light come on momentarily each time

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current
government regulations.
If any of these systems require service, the OBD
II system will turn on the Malfunction Indicator
Light (MIL). It will also store diagnostic codes
and other information to assist your service technician in making repairs. Although your
vehicle will usually be drivable and not need
towing, see an authorized dealer for service as
soon as possible.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (OBD II) and a connection
port to allow access to information related to
the performance of your emissions controls.
Authorized service technicians may need to
access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú
page 86.
CAUTION!
Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle must
be serviced before any emissions tests can
be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an acci -
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.
Automatic Transmission
The gear selector must be in the PARK (P) or
NEUTRAL (N) position before you can start the
engine. Press the brake pedal before shifting to
any driving gear.
NOTE:
You must press the brake pedal before shifting
out of PARK.
Normal Starting
Turn the ignition switch to the AVV (START)
position and release it when the engine starts.
If the engine fails to start within 10 seconds,
turn the ignition switch to the STOP (OFF/LOCK)
position, wait 10 to 15 seconds, then repeat
this procedure.
Cold Weather Operation
To ensure reliable starting at low temperatures,
use of an externally powered electric engine
block heater (available from an authorized
dealer) is recommended.To prevent possible engine damage while
starting at low temperatures, this vehicle will
inhibit engine cranking when the ambient
temperature is less than -31°F (-35° C) and the
oil temperature sensor reading indicates an
engine block heater has not been used. The
message “plug in engine heater” will be
displayed in the instrument cluster when the
ambient temperature is below -25°F (-32° C) at
the time the engine is shut off as a reminder.
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. Place the ignition in the AVV (START) position and release it when the engine
starts.
WARNING!
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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 transmission gear
selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren). A child could operate power
windows, other controls, or move the
vehicle.

21_VM_OM_EN_USC_t.book Page 58

STARTING AND OPERATING59
3. If the engine fails to start within ten
seconds, place the ignition in 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.
If Engine Fails To Start
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme Cold
Weather” procedure, and has not experienced
an extended park condition as identified in
“Extended Park Starting” procedure, it may be
flooded. Push the accelerator pedal all the way
to the floor and hold it there. Crank the engine
for no more than 15 seconds. This should clear
any excess fuel in case the engine is flooded. Leave the ignition key in the MAR (ON/RUN)
position, release the accelerator pedal and
repeat the “Normal Starting” procedure.
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:
CAUTION!
To prevent damage to the starter, do not
crank continuously for more than 10 seconds
at a time. Wait 10 to 15 seconds before trying
again.
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 transmission 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
Úpage 204.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.

60STARTING AND OPERATING

1. Locate the engine block heater cord
(behind the driver’s side headlamp).

2. Undo the hook-and-loop 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 hook-and-loop 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.
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
Ú page 259. NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera
-
tion. This should be considered a normal part of
the break-in and not interpreted as a concern.
Please check your oil level with the engine oil
indicator often during the break in period. Add
oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied. Also, be certain to
leave an automatic transmission in PARK.
The parking brake lever is located in the center
console. To apply the parking brake, pull the
lever up as firmly as possible. To release the
parking brake, pull the lever up slightly, push
the center button, then lower the lever
completely.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

Parking Brake

When the parking brake is applied with the
ignition switch in the ON position, the brake
warning light in the instrument cluster display
will illuminate.
NOTE:
When the parking brake is applied and the
automatic transmission is placed in gear, the
brake warning light will flash. If vehicle speed
is detected, a chime will sound to alert the
driver. Fully release the parking brake before
attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application. 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. For vehicles equipped with an automatic
transmission, apply the parking 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.
WARNING!
When exiting the vehicle, always remove
the key fob from the ignition and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat
-
tended 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 chil -
dren. A child could operate power windows,
other controls, or move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle or it may roll and cause
damage or injury. Also, be certain to leave
an automatic transmission in PARK. Failure
to do so may cause the vehicle to roll and
cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.
