2008 DODGE RAM 3500 GAS air condition

If your Remote Keyless Entry Transmitter (RKE) fails to
operate from a normal distance, check for these two
conditions:
1. Weak batteries in transmitter. The expected life of the
batteries is from one to two years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.Transmitter Battery Service
NOTE:Perchlorate Material ± special handling may apply,
see www.dtsc.ca.gov/hazardouswaste/perchlorate
The recommended replacement battery is CR2032.

24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Passenger Airbag On/Off Switch ± (2500/3500
Regular Cab Vehicles Only)
The passenger front airbag is to be turned off only if the
passenger:
²is an infant (less than one-year old) who must ride in
the front seat because there is no rear seat, because the
rear seat is too small for a rear-facing infant restraint orbecause the infant has a medical condition which
makes it necessary for the driver to be able to see the
infant;
²is a child, age 1 to 12 who must ride in the front seat
because there is no rear seat, because there is no rear
seat position available, or because the child has a
medical condition which makes it necessary for the
driver to be able to see the child;
²has a medical condition which makes passenger airbag
inflation (deployment) a greater risk for the passenger
than the risk of hitting the dashboard (instrument
panel) or windshield in a crash.
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 mi (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.
Avoid wide-open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high-quality, energy-conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Safety Checks You Should Make Inside The
Vehicle
Heater Defroster Ducts
Inspect the heater defroster ducts for proper operation.
Check for proper airflow through all defroster ducts. If
there are any questions regarding the operation of your
heater defroster ducts, have the system checked by an
authorized dealer.
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.) or if the front airbags have deployed. If there is any
question regarding belt or retractor condition, replace the
belt.
Airbag Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers or comes
on while driving, have the system checked by an autho-
rized dealer. If there is a problem with the airbag light,
the seat belt light will flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.

CAUTION!
Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Indicator Light
The indicator lights and remains lit for six to eight
seconds when the ignition is first turned ON. If the light
stays on, flickers or comes on while driving, have the
airbag system checked by an authorized dealer.
6. High Beam Indicator
This indicator shows that headlights are on high
beam.
7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulbcheck. During the bulb check, if the driver's seat belt is
unbuckled, a chime will sound. After the bulb check or
when driving, if the driver's seat belt remains unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to9Enhanced Driver Seat Belt Re-
minder System (BeltAlertt)9in the Occupant Restraints
section for more information.(See page 46 for more
information.)
8. Speedometer
The Speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/kph).
9. Oil Pressure Gauge Ð Premium Cluster Only
The pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading, under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized dealer.

CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
19. 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.
20. 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
