2008 DODGE RAM 2500 GAS trailer

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This is a nor-
mal part of the break-in and is not an indication of
difficulty.
CAUTION!
²During the first 500 mi (805 km) your new vehicle
is driven, do not tow a trailer. Doing so may
damage your axles, driveline and vehicle.
²Limit your speed to 50 mph (80 km/h) during the
first 500 mi (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!
²It 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 seri-
ously injured or killed.
²Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts.
²Be sure everyone in your vehicle is in a seat and
using a seat belt properly.

Set the top switch to the left or right for the left or right
mirror, and set it to the center off position to prevent
accidentally moving a mirror when you are finished
adjusting the mirror. To adjust a mirror, select left or right
with the top switch, and press one of the four arrows for
the direction you want the mirror to move.
Electric Rear Window Defroster and Heated
Sideview Mirrors ± If Equipped
The Electric Rear Window Defroster and Heated
Sideview Mirrors are activated by pressing the
heated grid button, located on the Climate Control panel,
with the ignition ON. Turning Off the rear window
defroster or the ignition will deactivate the Electric Rear
Window Defroster and Heated Sideview Mirrors feature.
These features turn off automatically after 15 minutes
have elapsed for the first activation per ignition cycle.
Each subsequent activation of these features per ignition
cycle will shut off automatically after 10 minutes have
elapsed. To reactivate, simply press the button again.
Trailer Towing Mirrors ± If Equipped
These mirrors are designed with an adjustable mirror
head to provide a greater vision range when towing

extra-wide loads. To change position inboard or out-
board, the mirror head should be rotated (flipped out or
in). A small blindspot mirror is integrated onto the main
mirror surface.
NOTE: Fold the trailer towing mirrors rearward prior
to entering an automated car wash.

NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gaugesº indicator will illuminate
and a single chime will sound.
10. Transfer Case Position
This display indicator shows the transfer case position
selection.
For additional information refer to ª4-Wheel Drive Op-
erationº in section 5 of this manual.
11. TOW HAUL
The TOW HAUL button is located at the end of the gear
shift lever. This light will illuminate when the TOW
HAUL OD/OFF button is pushed once.
12. OD/OFF
The OD/OFF button is located at the end of the gear shift
lever. This light will illuminate when the TOW HAUL
OD/OFF button is pushed twice.13. Temperature Gauge
The Temperature Gauge indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is operat-
ing satisfactorily. The gauge needle will likely indicate a
higher temperature when driving in hot weather, up
mountain grades, in heavy traffic, or when towing a
trailer. If the needle rises to the ª245É F (118É C)º mark,
stop the vehicle, shift into NEUTRAL, and increase the
engine idle speed for two to three minutes. If the tem-
perature reading does not return to normal, shut your
engine OFF and allow it to cool. Seek authorized service
immediately. Refer to ªCooling Systemº under ªMain-
taining Your Vehicleº in section 7.

27. 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. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
28. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
29. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.30. Low Fuel Warning Light
When the fuel level drops to 1/16 tank, the fuel
symbol will light and a single chime will sound.
NOTE:If your vehicle is equipped with an overhead
console module (CMTC), it is possible for DTE to display
ªLO FUELº before the low fuel warning light turns on in
the instrument cluster. This could occur because the low
fuel warning is set to a specified fuel tank volume and
DTE is an estimated distance calculation based on vehicle
fuel economy and remaining fuel tank volume.
Vehicle fuel tank volumes are as follows:
²26 gal (98 L) - 1500 short box models
²34 gal (128 L) - 1500/2500/3500 short box models
²35 gal (132 L) - 1500/2500/3500 long box models

Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it's rainy or humid. In most cases
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarettesmoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. For proper coolant type,
refer to ªRecommended Fluids and Genuine Partsº in
Section 7.
When using the air conditioner in extremely heavy traffic
in hot weather, especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
