and should not be relied upon as the primary
method by which the driver shifts the vehicle into
PARK.
The conditions under which AutoPark will engage
are outlined on the following pages. If the vehicle is not in PARK and the driver turns off
the engine, the vehicle may AutoPark.
AutoPark will engage when all of these conditions
are met:
Vehicle is equipped with an 8-speed transmis
-
sion
Driver door is ajar or if the driver door is
removed and the driver is not on the seat (seat
pad sensor detects driver missing)

Driver inattention could lead to failure to place
the vehicle in PARK. ALWAYS DO A VISUAL
CHECK that your vehicle is in PARK by verifying
that a solid (not blinking) “P” is indicated in
the instrument cluster display and on the gear
selector. If the "P" indicator is blinking, your
vehicle is not in PARK. As an added precau -
tion, always apply the parking brake when
exiting the vehicle.
AutoPark is a supplemental feature. It is not
designed to replace the need to shift your
vehicle into PARK. It is a back-up system and

and repeat the “Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically and will
decrease as the engine warms up.
STARTING THE ENGINE — DIESEL ENGINE
(IF EQUIPPED)
Before starting your vehicle, adjust your seat, both
inside and outside mirrors, and fasten your seat
belts.
The starter is allowed to crank for up to 25-second
intervals. Waiting two minutes between such
intervals will protect the starter from overheating.
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 auto -
matic 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 Ú page 343.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren 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.

148STARTING AND OPERATING
NOTE:Engine start-up in very low ambient temperature
could result in evident white smoke. This condition
will disappear as the engine warms up.
AUTOMATIC TRANSMISSION
Start the engine with the transmission gear
selector in the PARK (P) position. Apply the brake
before shifting to any driving range.
EXTREME COLD WEATHER
The cartridge block heater clips into the engine
block near the water jacket and transfers heat to
the coolant. It requires a 110–115 Volt AC
electrical outlet with a grounded, three-wire
extension cord. Its use is recommended for
environments that routinely fall below -10°F
(-23°C). It should be used when the vehicle has not
been running overnight or longer periods and
should be plugged in two hours prior to start. Its
use is required for cold starts with temperatures
under -20°F (-28°C).
NOTE:The engine block heater and heater cord are
factory installed options. If your vehicle is not
equipped, engine block heaters and heater cords
are available from an authorized Mopar® dealer.
A 12 Volt heater built into the fuel filter housing
aids in preventing fuel gelling. It is controlled by
a built-in thermostat.
A Diesel Pre-Heat system both improves engine
starting and reduces the amount of white
smoke generated by a warming engine.
NORMAL STARTING
Observe the instrument cluster lights when
starting the engine.
NOTE:Normal starting of either a cold or a warm engine is
obtained without pumping or pressing the accel -
erator pedal.

1. Always apply the parking brake.

2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
NOTE:A delay of the start of up to five seconds is possible
under very cold conditions. The “Wait to Start”
telltale will be illuminated during the preheat
process. When the engine “Wait To Start” telltale
turns off the engine will automatically crank.
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 position. A child could operate power
windows, other controls, or move the vehicle.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up
may cause serious injury or death.
CAUTION!
The engine is allowed to crank as long as
25 seconds. If the engine fails to start during
this period, please wait at least two minutes
for the starter to cool before repeating start
procedure.
If the Water in Fuel Indicator Light remains on,
DO NOT START engine before you drain the
water from the fuel filters to avoid engine
damage Ú page 368.
WARNING!
CAUTION!
If the Water in Fuel Indicator Light remains on,
DO NOT START the engine before you drain the
water from the fuel filters to avoid engine

23_JT_OM_EN_USC_t.book Page 148

STARTING AND OPERATING151
NOTE:Under certain conditions the Stop/Start system
may be temporarily disabled and the engine fan
will run after the engine is turned off to protect the
engine. These conditions are under high load and
high temperature conditions.
COOLING SYSTEM TIPS — AUTOMATIC
T
RANSMISSION
To reduce the potential for engine and
transmission overheating in high ambient
temperature conditions, take the following actions:
City Driving — When stopped, shift the transmis -
sion into NEUTRAL (N) and increase engine idle
speed.
Highway Driving — Reduce your speed.
Up Steep Hills — Select a lower transmission
gear.
Air Conditioning — Turn it off temporarily.
NOTE:If the coolant temperature is too high, the A/C will
automatically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the Low Oil Pressure Warning Light turns on while
driving, stop the vehicle and shut down the engine
as soon as possible. After the vehicle is safely
stopped, restart the engine and monitor the lamp. If the lamp is still illuminated, shut the engine off,
contact an authorized dealer, and do not operate
the vehicle until the cause is corrected. If the lamp
is no longer illuminated, the engine can be
operated, but should be taken to an authorized
dealer as soon as possible for further inspection.
NOTE:Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is
in the engine. The engine oil level must be checked
under the hood.
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Be on the alert for changes in
performance, sounds, and visual evidence that the
engine requires service. Some important clues are:
Engine misfiring or vibrating severely
Sudden loss of power
Unusual engine noises
Fuel, oil or coolant leaks
Sudden change, outside the normal operating
range, in the engine operating temperature
Excessive smoke
Oil pressure drop
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE (IF EQUIPPED)
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
see Ú page 424.
CAUTION!
If oil pressure falls to less than normal readings,
shut the engine off immediately. Failure to do so
could result in immediate and severe engine
damage.

23_JT_OM_EN_USC_t.book Page 151

152STARTING AND OPERATING
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.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE (IF EQUIPPED)
The diesel engine does not require a break-in
period due to its construction. Normal operation is
allowed, providing the following recommendations
are followed:
Warm up the engine before placing it under
load.
Do not operate the engine at idle for prolonged
periods.
Use the appropriate transmission gear to
prevent engine lugging.
Observe vehicle oil pressure and temperature
indicators.
Check the coolant and oil levels frequently.
Vary throttle position at highway speeds when
carrying or towing significant weight.
NOTE:Light duty operation such as light trailer towing or
no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy
and power may be seen at this time.
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 recommended viscosity and quality
grades Úpage 424. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
PARKING BRAKE
Before exiting the vehicle, make sure that the
parking brake is fully applied. Also, be certain to
leave an automatic transmission in PARK, or
manual transmission in REVERSE or FIRST gear.
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.
Parking Brake Lever

When the parking brake is applied with the ignition
switch ON, the Brake Warning Light in the
instrument cluster will illuminate.
NOTE:
When the parking brake is applied and the auto -
matic 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.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.
