2011 Ram 1500 light

To switch from the max load inflation pressure (cold) low
pressure warning threshold to the light load inflation
pressure (cold) low pressure warning threshold, begin by
placing the ignition switch in the RUN position. Next,
lower all four road tire pressures to the Light Load
Inflation Pressure values as listed on the SupplementalTire Pressure Information label. The Supplemental Tire
Pressure Information label is located on the rear face of
the driver door opening. Use an accurate tire gauge to
check the tire pressures when lowering all four tire
pressures. The vehicle may need to be driven above
15 mph (24 km/h) to receive this updated pressure
information. After all four tire pressures have been
lowered to the Light Load inflation pressures, press the
tire light load inflation switch. If the tire light load
inflation switch’s amber colored LED turns ON, the
TPMS is using the light load inflation pressure (cold) low
pressure warning thresholds.
If the tire light load inflation switch amber colored LED
flashes on and off for 10 seconds, after all four tire
pressures have been lowered to the Light Load inflation
pressures, the pressure in any one of the four tires may
not be at the light load inflation pressure (cold) values as
indicated for the Light Load condition as defined on the
Supplemental Tire Pressure Information label located on
Example Supplemental Tire Pressure Label

the rear face of the driver door. Using an accurate tire
pressure gauge, re-check the tire pressures for the light
load inflation pressure (cold) value.
WARNING!
It is the driver ’s responsibility to change to the max
load inflation pressure (cold) low pressure warning
threshold condition when not driving in the light
load condition as defined as two occupants (150 lbs
[68 kg] each) plus 200 lbs (91 kg) of cargo. The vehicle
“Light Load Definition” is found in the Supplemen-
tal Tire Pressure Information label located on the rear
face of the driver door. Failure to do so may cause you
to lose control resulting in a collision, causing seri-
ous or fatal injury.
To switch back to the max load inflation pressure (cold)
low pressure warning threshold, press the tire light load
inflation switch. It is not necessary to first fill the tires to the max load inflation pressure (cold) values to switch
the TPMS system to the max load inflation pressure
(cold) low pressure warning threshold. If after pressing
the tire light load inflation switch, and tire pressures are
below the max load inflation pressure (cold) low pressure
warning thresholds, the TPMS low pressure warning
telltale light (located in the instrument cluster) will turn
ON and a chime will sound. The tire pressures are now
required to be inflated to the max load inflation pressure
(cold) values described on the Tire and Loading Informa-
tion label. The Tire and Loading Information label is
located on the drivers side B-pillar. If the tire light load
inflation switch LED turns OFF, the TPMS has been reset
and the TPMS is using the max load inflation pressure
(cold) low pressure warning thresholds.

FUEL REQUIREMENTS
3.7L and 4.7L Engine
These engines are designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high quality unleaded “regular”
gasoline having an octane rating of 87. The use of premium gasoline is not recommended, as it will
not provide any benefit over regular gasoline in these
engines.
5.7L Engine
This engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having
an octane range of 87 to 89. The manufac-
turer recommends the use of 89 octane for
optimum performance. The use of premium gasoline is
not recommended, as it will not provide any benefit over
regular gasoline in these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
5

as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasoline that meets the WWFC speci-
fications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasolines contain oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability for the engine
and fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as Ethanol. Fuels blended with oxygenates
may be used in your vehicle.
CAUTION!
DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and driveability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Pump labels should clearly communicate if a
fuel contains greater than 10% Ethanol.
444 STARTING AND OPERATING

Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% Ethanol
are not the responsibility of the manufacturer and may
not be covered under warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosionTo fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
5
STARTING AND OPERATING 445

of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
or not his/her gasoline contains MMT. It is even more
important to look for gasolines without MMT in Canada,
because MMT can be used at levels higher than those
allowed in the United States. MMT is prohibited in
Federal and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emission control system.
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.(Continued)

ADDING FUEL
The fuel filler cap (gas cap) is located behind the fuel
filler door, on the left side of the vehicle. Open the fuel
door and remove the fuel cap by turning it counter-
clockwise.NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler 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 gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
