2014 JEEP GRAND CHEROKEE Diesel Supplement Manual

•Engine Will Not Start Service DEF System See Dealer
— This message will display when the fault detected is
not serviced after the Engine will not restart Service DEF
System See Dealer message is displayed on the next
subsequent restart. Your engine will not start unless you
vehicle is serviced by your authorized dealer. The mes-
sage will be accompanied by a single chime. Your
Malfunction Indicator Light will be continuously illumi-
nated. If the message appears and you can not start the
engine, we recommend you have your vehicle towed to
your nearest authorized dealer immediately.
NOTE:
• The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF)
to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service. •
The DEF gauge may also not immediately update after
a refill if the temperature of the DEF fluid is below
12°F (-11°C). The DEF line heater will possibly warm
up the DEF fluid and allow the gauge to update after
a period of run time. Under very cold conditions, it is
possible that the gauge may not reflect the new fill
level for several drives.

34 STARTING AND OPERATING

STARTING PROCEDURES
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 30-second
intervals. Waiting a few minutes between such intervals
will protect the starter from overheating.
WARNING!
•When leaving the vehicle, always make sure the
keyless ignition node is in the OFFmode, remove
the Key Fob from the vehicle and lock the vehicle.
(Continued)
WARNING! (Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children 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 shift
lever.
• 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™ ACC or RUN mode. A child
could operate power windows, other controls, or
move the vehicle.

STARTING AND OPERATING 35

NOTE:Engine start up in very low ambient temperature
could result in evident white smoke. This condition will
disappear as the engine warms up.
CAUTION!
•The engine is allowed to crank as long as 30 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. Refer
to “Maintenance Procedures/Draining Fuel/Water
Separator Filter” in “Maintaining Your Vehicle” for
further information.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Extreme Cold Weather
The engine block heater is a resistance heater installed in
the water jacket of the engine. It requires a 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion 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 cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR® dealer.
36 STARTING AND OPERATING

•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 start-
ing and reduces the amount of white smoke generated
by a warming engine.
Normal Starting Procedure — Keyless
Enter-N-Go™
Observe the instrument panel cluster lights when starting
the engine.
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal
1. Always apply the parking brake.
2. For vehicles equipped with an automatic transmis- sion, place the shift lever into the PARK position. 3. Press and hold the brake pedal while pressing 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 pre-heat process
and the start will commence upon the telltale going out.
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 damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
4. The system will take over and attempt to start the vehicle. If the vehicle fails to start, the starter will
disengage automatically after 30 seconds.

•When leaving the vehicle, always remove the key
fob 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 unattended is dangerous for a

or the shift lever. Do not leave the key fob in or
near the vehicle (or in a location accessible to
