2016 Ram 1500 Intake

1. Tachometer
•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter
•When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay
within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
NOTE:The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.3. 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 from an authorized
dealer.
4. Speedometer
•Indicates vehicle speed.
5. Fuel Gauge
•The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
6. Driver Information Display (DID)
•
When the appropriate conditions exist, this display
shows the Driver Information Display (DID) messages.
Refer to “Driver Information Display” in “Understand-
ing Your Instrument Panel” for further information.

Recirculation Control
Push the Recirculation Control button to
choose between outside air intake or recircula-
tion of the air inside the vehicle. A LED will
illuminate when you are in Recirculation
mode. Only use the Recirculation mode to temporarily
block out any outside odors, smoke, or dust, and to cool
the interior rapidly upon initial start-up in very hot or
humid weather.
NOTE:
•If the RECIRCULATION button is pushed when the
system is in Defrost mode, the Recirculation LED
indicator will flash three times and then turn off to
indicate Recirculation mode is not allowed.•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.
•The A/C can be deselected manually without disturb-
ing the mode control selection by pushing the A/C
button.
Air Outlets
The airflow from each of the instrument panel outlets can
be adjusted for direction, and turned on or off to control
airflow.
NOTE:For maximum airflow to the rear, the center
instrument panel outlets can be directed toward the rear
seat passengers.

Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.

WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle, which may result in
severe injury. Always back carefully straight down a
hill in REVERSE. Never back down a hill in NEU-
TRAL using only the vehicle brakes. Never drive
diagonally across a hill, always drive straight up or
down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only
be attempted when necessary, in a safe responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly andavoid damage to the environment. You should know
your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. You want
to use first gear in 4L (Low Range) and proceed very
slowly with a constant slow speed (3-5 mph [5–8 km/h]
maximum) and light throttle. Keep the vehicle moving;
do not try to accelerate through the crossing. After
crossing any water higher than the bottom of the axle
differentials, you should inspect all of the vehicle fluids
for signs of water ingestion.
