2009 DODGE DURANGO check engine light

theESP/TCS Indicator Lightbegins to flash during
acceleration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions. The “ESP/TCS
Indicator Light” becomes illuminated when the ESP-Off
button has been pressed or ESP is only partially available
caused by lack of engine management or brake thermal
model.
19. Transmission Temperature Indicator
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage, such as trailer towing. If this
light comes on, stop the vehicle and run the
engine at idle or faster, with the transmission in NEU-
TRAL until the light goes off.20. Electronic Throttle Control (ETC)
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the PARK position. The light
should turn off. If the light remains lit with the engine
running your vehicle will usually be drivable, however,
see an authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.

WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
22. Electronic Stability Program (ESP) / Brake Assist
System (BAS) Warning Lamp
The malfunction lamp for the Electronic Stabil-
ity Program (ESP) is combined with Brake
Assist System (BAS). The yellow ESP/BAS
warning lamp is in the instrument cluster it
comes on when the ignition switch is turned to the ON
position, it should go out with the engine running. If the
ESP/BAS warning lamp comes on continuously with the
engine running, a malfunction has been detected in either
the ESP or the BAS system. If this light remains on after
several ignition cycles, and the vehicle has been driven
several miles at speeds greater than 30 mph (48 km/h),
see an authorized dealer as soon as possible.

NOTE:The ESP control system will make buzzing or
clicking sounds when it is actively operating.
23. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system which monitors
the emissions and engine control system. If the
vehicle is ready for emissions testing, the MIL will come
on when the ignition is first turned on and remain on, as
a bulb check, until the engine is started. If the vehicle is
not ready for emissions testing, the MIL will come on
when the ignition is first turned on and remain on for
15 seconds, then blink for 10 seconds, and remain on until
the vehicle is started. If the MIL does not come on during
starting, see an authorized dealer as soon as possible.
If the MIL comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.Although your vehicle will usually be drivable and not
need towing, see an authorized dealer for service as soon
as possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine 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. See an authorized dealer for
service immediately.
24. Tire Pressure Monitoring Telltale Light
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

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips — Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
TOW/HAUL feature should be selected.
NOTE:Using the TOW/HAUL feature while operating
the vehicle under heavy operating conditions will im-
prove performance and extend transmission life by re-
ducing excessive shifting and heat build up. This action
will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. For transmission
fluid change intervals, refer to “Maintenance Schedule”
in Section 8.NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the TOW/HAUL feature ON when driving in
hilly areas or shift the transmission to DRIVE position 2
on more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can resume cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
370 STARTING AND OPERATING

problem persists, the message will appear the next time
the vehicle is started. This might indicate a damaged cap.
If the problem is detected twice in a row, the system will
turn on the MIL. Resolving the problem will turn the MIL
off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recentlyserviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.

•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased
emissions.
Brake System
Brake Master Cylinder — Fluid Level Check
The fluid level in the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid
to bring level to the full mark on the side of the reservoir
of the brake master cylinder. Be sure to clean the top of
the master cylinder area before removing the cap. With
disc brakes, fluid level can be expected to fall as the brakepads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid level is abnormally
low, check system for leaks.
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
WARNING!
•Use of brake fluid that may have a lower initial
boiling point, or is unidentified as to specifica-
tions may result in sudden brake failure during
hard prolonged braking. You could have an
accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
416 MAINTAINING YOUR VEHICLE

•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
