2019 Ram 2500 fuel consumption

186 GETTING TO KNOW YOUR INSTRUMENT PANEL
— Low Fuel Warning Light
When the fuel level reaches approximately 3.2 gal (12 L) this
light will turn on, and remain on until fuel is added.
A single warning chime will sound with Low Fuel Warning.
— Low Coolant Level Warning Light
This telltale will turn on to indicate the vehicle coolant level
is low.
— Tire Pressure Monitoring System (TPMS) Warning
Light
The warning light switches on and a message is displayed to
indicate that the tire pressure is lower than the recom -
mended value and/or that slow pressure loss is occurring. In
these cases, optimal tire duration and fuel consumption may
not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom
-
mended by the vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or
tire inflation pressure label, you should determine the proper
tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi -
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure.CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

542 SERVICING AND MAINTENANCE
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the driver's
side B-Pillar or rear edge of the driver's side door.
At least once a month:
• Check and adjust tire pressure with a good qualitypocket-type pressure gauge. Do not make a visual judge -
ment when determining proper inflation. Tires may look
properly inflated even when they are under-inflated. • Inspect tires for signs of tire wear or visible damage.
Inflation pressures specified on the placard are always “cold
tire inflation pressure”. Cold tire inflation pressure is
defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of three hours. The cold
tire inflation pressure must not exceed the maximum infla
-
tion pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range of
outdoor temperatures, as tire pressures vary with tempera -
ture changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in the
Winter. CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.
