2012 RAM CHASSIS CAB turn signal bulb

Daytime Running Lights — If Equipped
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear
except PARK. This provides a constant  Lights ON 
condition until the ignition is turned OFF. The lights
illuminate at less than 50% of normal intensity. If the
parking brake is applied, the Daytime Running Lights
(DRL) will turn OFF. Also, if a turn signal is activated, the
DRL lamp on the same side of the vehicle will turn off for
the duration of the turn signal activation. Once the turn
signal is no longer active, the DRL lamp will illuminate.
Multifunction Lever
The multifunction lever is located on the left side of the
steering column.
Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show
proper operation of the front and rear turn signal lights. NOTE: If either light remains on and does not flash, or
there is a very fast flash rate, check for a defective outside
light bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective. Turn Signal Lever

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The Tachometer indicates engine speed in revolutions per
minute (RPM x 1000).
CAUTION!Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
damage may occur.
2. Turn Signal Indicators
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
• A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on. • Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate.
3. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON/RUN position.
4. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
