2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
Transmitter Battery Service
The recommended replacement battery is a 3V lithium
2016 cell. This transmitter requires two batteries.NOTE:Do not touch the battery terminals that are on
the back housing or the printed circuit board.
1. With transmitter buttons facing down, use a flat blade
or dime to pry the two halves of the transmitter apart.
Make sure not to damage the rubber gasket during
removal.
2. Remove and replace the batteries. Be careful not to
disturb the metal terminal near the batteries. Install the
batteries with the positive terminal up, reference the note
9+ SIDE UP9on the inside of the bottom half of the
transmitter case. Avoid touching the new batteries with
your fingers. Skin oils may cause battery deterioration. If
you touch a battery, clean it with rubbing alcohol.
3. To reassemble the transmitter case snap the two halves
together. Make sure there is an even gap between the two
halves. Test transmitter operation.
28 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back should use the lap/shoulder belt in a rear seat.
²Make sure that the child is upright in the seat.
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.
NEW ENGINE BREAK-IN
Your Cummins 24 Valve Turbo Diesel engine does not
require a normal break-in period due to its construction.
Normal operation is allowed, provided the following
recommendations are followed:
NOTE:Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
²Warm up the engine before placing it under load.
²Do not operate the engine at idle for prolonged
periods.
²Use the appropriate transmission gear to prevent
engine lugging.
²Observe vehicle oil pressure and temperature indica-
tors.

²Check the coolant and oil levels frequently.
²Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins Diesel
engine, engine run-in is enhanced by loaded operating
conditions which allow the engine parts to achieve final
finish and fit during the first 6,000 miles (10 000 km).
CAUTION!
²During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your vehicle.
²Limit your speed to 50 mph (80 km/h) during the
first 500 miles (805 km) of towing.
SAFETY TIPS
Transporting Passengers
This vehicle is designed to carry passengers in the cab
only. For safety reasons, NEVER TRANSPORT PASSEN-
GERS IN THE CARGO AREA.
WARNING!
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Lock Your Vehicle
Always remove the keys from the ignition and lock all
doors when leaving the vehicle unattended, even in your
own driveway or garage. Try to park your vehicle in a
well-lighted area and never invite theft by leaving ar-
ticles of value exposed.
Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a poten-
tially toxic gas that by itself is colorless and odorless.
To avoid inhaling these gases, the following precau-
tions should be observed:
²Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
²If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
²The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required.

Safety Checks You Should Make Inside The
Vehicle
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 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see you
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
seatbelt 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.
Lights
Check the operation of all exterior lights. Check turn signal
and high beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 seconds as a bulb check.
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 seat belt remains unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to9Enhanced Driver Seat Belt Re-
minder System (BeltAlertŸ)9in the Occupant Restraints
section for more information.
8. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour.
9. Oil Pressure Gauge
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.NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gagesº indicator will illuminate
and a single chime will sound.
10. Cargo Lamp
The Cargo Lamp light will illuminate when the Cargo
Lamp is activated from the dimmer control switch,
located next to the headlight switch.
11. Door Ajar
The Door Ajar light will illuminate when any
door is opened. When the ignition is ON the
Door Ajar light will stay illuminated until the
open door is closed. When the ignition is OFF
the Door Ajar light will stay illuminated until the open
door is closed or the battery saver feature automatically
turns the light off.

27. Low Fuel Warning Light
Glows when the pointer is between ªEº and 1/8
indication mark (approximately 15% of tank vol-
ume) on the fuel gauge. When the fuel gauge
pointer is on ªEº (equivalent to Distance To Empty [DTE]
= 0 on the overhead console if so equipped) there is
reserve fuel capacity, which corresponds to approxi-
mately 8% of tank volume. This reserve capacity was put
in place to prevent the likelihood of customers running
out of fuel when operating at maximum load conditions
in areas where there aren't many gas stations.
Ram fuel tank volumes are as follows:
²34 gallons - 2500/3500 short box models
²35 gallons - 2500/3500 long box models28. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)
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.
29. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
