warning Ram 2500 2016 Diesel Supplement

•Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as
possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that the engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
• Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to cool
an overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the
system is hot or under pressure.
• Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check
with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based

•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned in front of the radiator
and the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air
rapidly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through
another hose to the intake manifold of the engine. This
cooling process enables more efficient burning of fuel
resulting in fewer emissions. To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and
radiator clean and free of debris. Periodically check the
hoses leading to and from the charge air cooler for cracks
or loose clamps resulting in loss of pressure and reduced
engine performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the “Brake System Warning Light” indicates
system failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
144 MAINTAINING YOUR VEHICLE

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.
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 accident.
• 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 an accident.

MAINTAINING YOUR VEHICLE 145

WARNING!
•You can be badly injured working on or around a
motor vehicle. Do only service work for which you
have the knowledge and the right equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
• Failure to properly inspect and maintain your ve-
hicle could result in a component malfunction and
effect vehicle handling and performance. This
could cause an accident.
Additional Maintenance — B6 To B20 Biodiesel
NOTE:
• Under no circumstances should oil change intervals
exceed 8,000 miles (12 875 km) or six months, which-
ever comes first when using Biodiesel blends greater
than 5% (B5).
• The owner is required to monitor mileage for B6-B20
biodiesel, the automatic oil change indicator system
does not reflect the use of biofuels.

MAINTENANCE SCHEDULE 159

•Fuel meets minimum requirement
• Water In Fuel Indicator Light is not illuminated
• Wait To Start Light is not illuminated
WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled.
• Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
Remote Start Abort Message
The following messages will display in the EVIC/DID if
the vehicle fails to remote start or exits remote start
prematurely:
• Remote Start Aborted - Door Ajar
• Remote Start Aborted - Hood Ajar
• Remote Start Aborted - Fuel Low
• Remote Start Aborted - System Fault
The EVIC/DID message stays active until the ignition is
turned to the ON/RUN position.
To Enter Remote Start Mode
Push and release the REMOTE START button
on the RKE transmitter twice, within five sec-
onds. The parking lights will flash and the horn

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 171

NOTE:In order to ensure proper operation, the Elec-
tronic Speed Control System has been designed to shut
down if multiple Speed Control functions are operated at
the same time. If this occurs, the Electronic Speed Control
System can be reactivated by pushing the Electronic
Speed Control ON/OFF button and resetting the desired
vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster will illuminate. To turn the system
off, push the ON/OFF button a second time. The Cruise
Indicator Light will turn off. The system should be
turned off when not in use.
WARNING!
Leaving the Electronic Speed Control system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have an accident. Always
leave the system OFF when you are not using it.
To Set A Desired Speed
Turn the Electronic Speed Control ON. When the vehicle
has reached the desired speed, push the SET (-) button
and release. Release the accelerator and the vehicle will
operate at the selected speed.
NOTE: The vehicle should be traveling at a steady speed
and on level ground before pushing the SET (-) button.

To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE:The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
