2007 DODGE RAM 2500 DIESEL brake light

STEERING WHEEL LOCK — IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock. This lock prevents steering the vehicle with-
out the ignition key. If the steering wheel is moved no
more than 1/2 turn in either direction and the key is not
in the ignition switch, the steering wheel will lock.
If You Wish To Manually Lock The Steering
Wheel:
With the engine running, turn the steering wheel upside
down, turn off the engine and remove the key. Turn the
steering wheel slightly in either direction until the lock
engages.
To Release The Steering Wheel Lock:
Insert the key in the ignition switch and start the engine.
If the key is difficult to turn, move the wheel slightly to
the right or left to disengage the lock.
NOTE: If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON positions, and the
brake pedal is depressed.
SENTRY KEY — IF EQUIPPED
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys, which have an embedded
electronic chip (transponder), to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate

WARNING!
•Do not put anything on or around the airbag covers or
attempt to manually open them. You may damage the
airbags and you could be injured because the airbags are
not there to protect you. These protective covers for the
airbag cushions are designed to open only when the airbags
are inflating.
•Do not mount any aftermarket equipment such as trailer
brake controllers, snowplow controllers, auxiliary light
switches, radios, etc. on or behind the knee bolster. Knee
bolsters are designed to work with the air bag and seat belt
to protect you. Mounting any additional equipment on or
behind the knee bolster can cause injury during a crash.
•If your vehicle is equipped with window bags, do not stack
luggage or other cargo up high enough to block the location
of the window bag. The area where the window bag is
located should remain free from any obstructions.
•If your vehicle is equipped with window bags, do not have
any accessory items installed which will alter the roof,
including adding a sunroof to your vehicle. Do not add roof
racks that require permanent attachments (bolts or screws)
for installation on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
NOTE: Do not use a clothing bar mounted to the coat
hooks in this vehicle. A clothing bar will impede the
proper performance of the window bags.
Airbags inflate in moderate to high speed impacts. Along
with the seatbelts, front airbags work with the instrument
panel knee bolsters to provide improved protection for
the driver and front passenger. Window bags also work
with seat belts to improve occupant protection.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions. If your vehicle is so equipped,
the window bag on the crash side of the vehicle is
triggered in moderate to severe side collisions. In certain
types of collisions, both the front and side airbags may be
triggered. But even in collisions where the airbags work,
you need the seat belts to keep you in the right position
for the airbags to protect you properly.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Your vehicle is equipped with plastic headlight lenses
that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed. To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other abrasive materials to clean the lenses.
Daytime Running Lights (Canada Only and Fleet
Vehicles)
The headlights on your vehicle will illuminate when the
engine is started. This provides a constant
Lights ON
condition until the ignition is turned OFF. The lights
illuminate at less than 50% of normal intensity. If the
parking brake is applied the Daytime Running Lights
will turn off.

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.
18. Brake System Warning Light
This light illuminates when the ignition key is turned to
the ON position and remains on for a few seconds. If the
light stays on longer, it may be an indication that the
parking brake has not been released. This light will
illuminate if the brake fluid is low, especially when
braking or accelerating hard. This light will illuminate if
the ABS indicator light has a malfunction. This light will
flash if the engine is running and the parking brake is on. If the light remains on when the parking brake is
released, it indicates a possible brake hydraulic system
malfunction. In this case, the light will remain on until
the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.
19. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual. This
light will come on when the ignition key is turned to the
ON position and may stay on for five seconds. If the ABS
light remains on or comes on during driving, it indicates
184 UNDERSTANDING YOUR INSTRUMENT PANEL

that the anti-lock portion of the brake system is not
functioning and that service is required. See your autho-
rized dealer immediately. The ABS light could also
illuminate during loss of traction and remain illuminated
until the brake pedal is pressed.
20. Cargo Light
The Cargo Lamp light will illuminate when the Cargo
Lamp is activated by pressing the Cargo Light Button on
the headlight switch.
21. Electronic Throttle Control (ETC) This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate 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 for 15 seconds as a bulb check. If the light does not
come on during starting, have the system checked by an
authorized dealer.
22. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required.
23. Front Fog Light Indicator — If Equipped
This light shows when the front fog lights are ON.

250 STARTING AND OPERATING

The Cummins Diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 volt AC electrical
outlet with a grounded, three-wire extension cord.
NOTE: The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your 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 heated intake air system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
Normal Starting Procedure — Engine Manifold
AirTemperature Above 66°F (19°C)
Observe the Instrument Panel Cluster lights when start-
ing the engine.
1. Always apply the parking brake.
2. Shift into PARK for an automatic transmission. Fully
depress and hold the clutch and shift into NEUTRAL for
a manual transmission. Models with manual transmis-
sion are equipped with a clutch interlocking cranking
system. The clutch must be fully depressed to start the
vehicle.
3. Turn the ignition key to the ON position and look at
the instrument panel cluster lamps.
