fuel cap DODGE RAM 5500 CHASSIS CAB 2009 4.G Owners Manual

26. Low Fuel LightThis light illuminates when the pointer is between
“E” and 1/8 indication mark (approximately 15%
of tank volume) on the fuel gauge. When the fuel
gauge pointer is on “E” (equivalent to Distance To Empty
[DTE]=0ontheoverhead 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 fuel stations.
Fuel tank volumes are as follows:
•52 gal (197 L) - Standard Rear Tank
•22 gal (83 L) - Optional Mid Ship Tank
27. CRUISE Indicator This indicator lights when the electronic speed
control system is turned on.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the frequency and/or
time in hours and minutes (depending on your radio
model) whenever the ignition switch is in the ON or ACC
position.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
On the RAQ radio the time button alternates the location
of the time and frequency on the display. On the REF only
one of the two, time or frequency, is displayed at a time.
Clock Setting Procedure
1. Press and hold the time button until the hours blink.
2. Adjust the hours by turning the right side Tune/
Audio control.

WARNING! (Continued)
•Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
ADDING FUEL
The fuel tank filler tube has a restricting door about 2 in
(50 mm) inside the opening. If using a portable fuel
container, it should have a flexible nozzle long enough to
force open the restricting door.
CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system. Also, a
poorly-fitted aftermarket cap can cause the MIL
(Malfunction Indicator Light) to illuminate due to
fuel vapors escaping from the system.
•A poorly fitting gas cap may cause the MIL to turn
on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE: When the fuel nozzle “clicks” or shuts off the
fuel tank is full.

WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running. This is in violation of most state and
federal fire regulations and will cause the MIL to
turn on.
NOTE: Tighten the gas cap 1/4 turn until you hear one
click. This is an indication that the cap is properly
tightened.
If the gas cap is not tightened properly, the Malfunction
Indicator Light will come on, Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap (Gas Cap) Message
If the vehicle’s diagnostic system determines that the fuel
filler cap in loose, improperly installed or damaged, a
GASCAP message will be displayed in the instrument
cluster. Tighten the gas cap until a “clicking” sound is
heard. This is an indication that the gas cap is properly
tightened. Press the odometer reset button to turn the
message off. If the problem persists, the message will
appear the next time the vehicle is started. This might
indicate a damaged cap. If the problem is detected twice
in a row, the system will turn on the MIL. Resolving the
problem will turn the MIL off.

Tire Size
The tire size on the Label represents the actual tire size on
your vehicle. Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Vehicles with 5.7L engines are equipped with a sophisti-
cated onboard diagnostic system called OBD II. This
system monitors the performance of the emissions, en-
gine, and automatic transmission control systems. When
these systems are operating properly, your vehicle will
provide excellent performance and fuel economy, as well
as engine emissions well within current government
regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
Loose Fuel Filler Cap Message
If the vehicle’s diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
gASCAP message will be displayed in the instrument
cluster. Tighten the gas cap until a “clicking” sound is
heard. This is an indication that the gas cap is properly
tightened. Press the odometer reset button to turn the
message off. If the problem persists, the message will

Change Engine Oil
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API certified and meet
the requirements of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade)
For trucks with a 5.7L engine operating under a gross
combined weight rating of 14,000 lbs (6,350 kg) or greater,
SAE 5W-30 engine oil is recommended for all operating
temperatures.
For all other trucks with a 5.7L engine operating under a
gross weight rating less than 14,000 lbs (6,350 kg) SAE
5W-20 engine oil is recommended for all operating tem-
peratures. These engine oils improve low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
“Engine Compartment” in this section.
Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
