2008 DODGE RAM 2500 POWER WAGON low oil pressure

INSTRUMENT CLUSTER DESCRIPTION
1. 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.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltage Gauge
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery ischarged. If the pointer moves to either extreme left or
right and remains there during normal driving, the
electrical system should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gagesº indicator will illuminate
and a single chime will sound. The ªCheck Gagesº
indicator may also illuminate prior to the voltage gauge
moving out of normal range. In either case, see you local
authorized Dealer for system service.
3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating.
4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.

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 6 to 8 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 5 to 8 seconds as a bulb check.During the bulb check, if the driver's seat belt is unbuck-
led, 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 continu-
ously. Refer to9Enhanced Driver Seat Belt Reminder
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.(See page 413 for more
information.)

TPMS ªLight Loadº Reset Switch ± If Equipped
The TPMS ºLight Loadº reset switch allows you to
choose between Light Load vehicle conditions and Max
Load vehicle conditions tire pressures and related TPMS
warning levels. The switch is located in the instrument
panel, below the climate control panel. For additional
information refer to ªTire Pressure Monitoring System
(TPMS) Ð If Equippedº in section 5 of this manual.
25. 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 thislight comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
26. 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.
27. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
28. 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

WARNING!
Tires and spare tire should be replaced after six years,
regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You
could lose control and have an accident resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.
342 STARTING AND OPERATING

WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided.
7. Remove wheel blocks. Do not install chrome or alu-
minum wheel center caps on the spare wheel. This may
result in cap damage.
8. Lower the jack to its fully closed position. If the jack
will not lower by turning the dial (thumb wheel) by
hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack, and
tools as previously described.
9. Adjust the tire pressure when possible.NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.Hub Caps
The hub caps must be removed before raising the vehicle
off the ground.
For 2500/3500 single rear wheel (SRW) models, use the
blade on the end of the lug wrench to pry the hub cap off.
Insert the blade end into the pryoff notch and carefully
pop off the hub cap with a back and forth motion.
CAUTION!
Use a back and forth motion to remove the hub cap.
Do not use a twisting motion when removing the hub
cap, damage to the hub cap finish may occur.
WHAT TO DO IN EMERGENCIES 397

²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under ªOdometer/Trip Odometerº under ªIn-
strument Cluster Descriptionº in Section 4 of this
manual.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level whilethe vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
²Check all lights and other electrical items for correct
operation.
