Up And Down Arrow Buttons:
Push and release the up and down
arrow buttons to scroll upward and down -
ward through the main menu and submenus
or adjust the illumination on the instrument
panel when the headlights are on.
CHANGE ENGINE OIL — IF EQUIPPED
Your vehicle is equipped with an engine oil
change indicator system. The “Change Engine
Oil” message will display in the instrument
cluster display. The engine oil change indicator
system is duty cycle based, which means the
engine oil change interval may fluctuate,
dependent upon your personal driving style. Unless reset, this message will continue to
display each time you turn the ignition switch to
the ON/RUN position. To turn off the message
temporarily, push and release the
MODE
button . To reset the oil change indicator system
(after performing the scheduled maintenance),
refer to the following procedure.

1. Turn the ignition switch to the ON position (do not start the engine).

2. Fully push the accelerator pedal slowly, three times, within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:
If the indicator message illuminates when you
start the vehicle, the oil change indicator
system did not reset. If necessary, repeat this
procedure.

STARTING AND OPERATING81
TRAILER TOWING WEIGHTS (MAXIMUM
T
RAILER WEIGHT RATINGS)
NOTE:
For trailer towing information (maximum trailer
weight ratings) refer to the following website
addresses:
ramtrucks.com/en/towing_guide/
ramtruck.ca (Canada)
rambodybuilder.com
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.

Weight Distribution
Consider the following items when computing
the weight on the rear axle of the vehicle:The tongue weight of the trailer.
The weight of any other type of cargo or
equipment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options or
dealer-installed options must be considered as
part of the total load on your vehicle. Refer to the Tire And Loading Information placard for the
maximum combined weight of occupants and
cargo for your vehicle Ú
page 245.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the
Scheduled Servicing Úpage 211. When towing
a trailer, never exceed the GAWR or GCWR
ratings.
CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the
rear can cause the trailer to sway severely
side to side which will cause loss of control of
the vehicle and trailer. Failure to load trailers
heavier in front is the cause of many trailer
collisions.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.

Based on engine operation conditions, the oil
change indicator message will illuminate in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, and
extremely hot or cold ambient temperatures will
influence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km)
since last reset. Have the vehicle serviced as
soon as possible, within the next 500 miles
(805 km).
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to the steps described under
Instrument Cluster Display Ú
page 45.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers. Severe Duty All Models

Vehicles that are operated in a dusty and off-road
environment, or predominately at idle or very low
engine RPM are known as Severe Duty vehicles.
It is recommended that you change the engine oil
at 4,000 miles (6,500 km) or 350 hours of
engine run time.

Once A Month Or Before A Long Trip:
Check engine oil level
Check windshield washer fluid level
Check the tire pressures and look for unusual
wear or damage. Rotate at the first sign of
irregular wear, even if it occurs before the oil
indicator system turns on
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
and fill as needed
Check function of all interior and exterior
lights

212SERVICING AND MAINTENANCE
MAINTENANCE PLAN
Refer to the maintenance plan for the required maintenance intervals. More frequent maintenance may be needed in severe conditions, such as dusty
areas and very short trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be required.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
Inspect battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect brake pads, shoes, rotors, drums, hoses and park brake.
Inspect engine cooling system protection and hoses.
Inspect exhaust system.
Inspect engine air cleaner if using in dusty or off-road conditions.
Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty
conditions.

SERVICING AND MAINTENANCE251
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.

Tire Tread

These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an
inch (1.6 mm). When the tread is worn to the
tread wear indicators, the tire should be
replaced.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replace -
ment.
Distance driven.
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is
highly recommended. NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and tear
in existing tires.
Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement Tires

The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph
on “Tread Wear Indicators” in this section. Refer
to the Tire and Loading Information placard or the
Vehicle Certification Label for the size
designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the
original equipment tire sidewall.

See the Tire Sizing Chart example found in the
Tire Safety Information section of this manual
for more information relating to the Load Index
and Speed Symbol of a tire Ú
page 241.
1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can result
in sudden tire failure. You could lose control
and have a collision resulting in serious injury
or death.
