2018 Ram 1500 interior lights

NOTE:
•The charging system is independent from load reduc-
tion. The charging system performs a diagnostic on the
charging system continuously.
• If the Battery Charge Warning Light is on it may indicate
a problem with the charging system. Refer to “Battery
Charge Warning Light” in “Getting To Know Your
Instrument Panel” for further information.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
• Heated Seat/Vented Seats/Heated Wheel
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC Power Inverter System
• Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
• The charging system cannot deliver enough electrical
power to the vehicle system because the electrical loads are larger than the capability of charging system. The
charging system is still functioning properly.
• Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights,
overloaded power outlets +12V, 115V AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping).
• Installing options like additional lights, upfitter electri-
cal accessories, audio systems, alarms and similar de-
vices.
• Unusual driving cycles (short trips separated by long
parking periods).
• The vehicle was parked for an extended period of time
(weeks, months).
• The battery was recently replaced and was not charged
completely.
• The battery was discharged by an electrical load left on
when the vehicle was parked.
• The battery was used for an extended period with the
engine not running to supply radio, lights, chargers,
+12V portable appliances like vacuum cleaners, game
consoles and similar devices.
188 GETTING TO KNOW YOUR INSTRUMENT PANEL

What to do when an electrical load reduction action
message is present (“Battery Saver On” or “Battery Saver
Mode”)
During a trip:
•Reduce power to unnecessary loads if possible:
– Turn off redundant lights (interior or exterior)
– Check what may be plugged in to power outlets +12V, 115V AC, USB ports
– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)
After a trip:
• Check if any aftermarket equipment was installed (ad-
ditional lights, upfitter electrical accessories, audio sys-
tems, alarms) and review specifications if any (load and
Ignition Off Draw currents).
• Evaluate the latest driving cycles (distance, driving time
and parking time).
• The vehicle should have service performed if the mes-
sage is still present during consecutive trips and the
evaluation of the vehicle and driving pattern did not
help to identify the cause.WARNING LIGHTS AND MESSAGES
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or passenger seat belt
is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver ’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraints Systems” in “Safety” for
further information.
— Air Bag Warning Light
This light indicates a fault with the air bag, and will turn on
for four to eight seconds as a bulb check when the ignition
is placed in the ON/RUN or ACC/ON/RUN position.
This light will illuminate with a single chime when a fault
with the air bag has been detected, it will stay on until the
fault is cleared. If the light is either not on during startup,
stays on, or turns on while driving, have the system
inspected at an authorized dealer as soon as possible.

•As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air bag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your clothing,
follow the garment manufacturer ’s instructions for
cleaning.
Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will
not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assem-
blies replaced by an authorized dealer immediately.
Also, have the Occupant Restraint Controller System
serviced as well. NOTE:
•
Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine whether
to have the Enhanced Accident Response System perform
the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.

NOTE:Change Engine Oil at 4,000 miles (6,500 km) or 350
hours of engine run time if the vehicle is operated in a
dusty and off road environment or is operated predomi-
nantly at idle, or only very low engine RPM’s. This type of
vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check tire pressure and look for unusual wear or
damage. Rotate tires 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, power steering (2500/3500 Models
Only) and automatic transmission (six-speed only) and
fill as needed
• Check function of all interior and exterior lightsMaintenance Plan
Required Maintenance
Refer to the Maintenance Plan on the following pages for
required maintenance.
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 automatic transmission fluid if equipped
with dipstick.
• 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.
• Lube the front drive shaft fitting (2500/3500 (4x4)
models only).
