engine DODGE DURANGO 2011 3.G Service Manual

Summer Operation
NOTE:In some cases during high temperature trailer
tow operation the Air Conditioning system performance
may be reduced. This is to help protect the engine from
overheating during the high load condition.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other
obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the key fob in
the ignition switch. A child could operate power
windows, other controls, or move the vehicle.
Automatic Transmission
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Using Fob With Integrated Key (Tip Start)
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
336 STARTING AND OPERATING

Do notpress the accelerator. Use the Fob with Integrated
Key to briefly turn the ignition switch to the START
position and release it as soon as the starter engages. The
starter motor will continue to run, and it will disengage
automatically when the engine is running. If the engine
fails to start, the starter will disengage automatically in
10 seconds. If this occurs, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Keyless Enter-N-Go – If Equipped
This feature allows the driver to oper-
ate the ignition switch with the push

START/STOP button is installed and
the Remote Keyless Entry (RKE) trans-
mitter is in the passenger compart-
ment.

position (OFF position for Keyless Enter-N-Go).
Normal Starting
Using The ENGINE START/STOP Button
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
To start the engine, the transmission must be in PARK or
NEUTRAL. Press and hold the brake pedal while press-
ing the ENGINE START/STOP button once. The system
takes over and attempts to start the vehicle. If the vehicle
fails to start, the starter will disengage automatically after

the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the shift lever is not in PARK, the ENGINE START/
STOP button must be held for two seconds and vehicle
speed must be above 5 mph (8 km/h) before the engine
will shut off. The ignition switch position will remain in
the ACC position until the shift lever is in PARK and the
button is pressed twice to the OFF position. If the shift
lever is not in PARK and the ENGINE START/STOP
button is pressed once, the EVIC (if equipped) will
display a “Vehicle Not In Park” message and the engine
will remain running. Never leave a vehicle out of the
PARK position, or it could roll.
338 STARTING AND OPERATING

NOTE:If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after
30 minutes of inactivity and the ignition will switch to the
OFF position.
Keyless Enter-N-Go Functions – With Driver ’s Foot
OFF The Brake Pedal (In PARK Or NEUTRAL
Position)

STARTING AND OPERATING 339

If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission 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 improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.
