2016 Ram 1500 oil level

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.

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, or air conditioning. Such damage is
not covered by the New Vehicle Limited Warranty.
If a flush is needed because of component malfunc-
tion, use only the specified fluid for the flushing
procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.7

With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Use only the manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
(Continued)
WARNING!(Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.

Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. This inspection should be made with the vehicle in
a level position.
For 1500 Model axles, the fluid level should be even with
the bottom of the fill hole (within 1/4 in (6.4 mm) of edge
of hole) for the FDU215 HD front axle and C235FE rear
axle.
For all 2500/3500 Model axles, the fluid level should be
1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on
the 9.25 in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on
10.5 in rear axles. The 11.5 in rear axle level should be 1/4
in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole.
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials
1500 Model rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) MOPAR Limited
Slip Additive be added to the gear lubricant. Refer to
“Fluids, Lubricants, And Genuine Parts” in “Maintaining
7
MAINTAINING YOUR VEHICLE 825

Your Vehicle” for further information. The MOPAR Lim-
ited Slip Additive should be added to the gear lubricant
whenever a fluid change is made to an axle equipped
with a Limited Slip Differential.
2500/3500 Model axlesDO NOT REQUIREany limited
slip oil additive (friction modifiers).
NOTE:When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive), the
Limited Slip Additive should be added before the gear
lubricant is added to insure proper additive fill.
Transfer Case
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in this
section for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid. No chemical flushes should be used

5. Place the shift lever momentarily into each gear posi-
tion (allowing time for the transmission to fully en-
gage in each position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until
seated.
7. Remove the dipstick again and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level.Do not overfill.Use
ONLY the specified fluid (seeFluids, Lubricants, And
Genuine Partsfor fluid specifications). After adding
any quantity of oil through the dipstick tube, wait aminimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at 60-70°F / 16-21°C. Only use the COLD
region of the dipstick as a rough reference when setting
the fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as required,
once the transmission reaches normal operating tempera-
ture.
CAUTION!
If the fluid temperature is below 50 °F (10 °C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid.
