2012 Ram 5500 Chassis Cab climate control

Front Blower Control
There are four blower speeds. Use this
control to regulate the amount of air
forced through the system in any
mode you select. The blower speed
increases as you move the control
clockwise from the OFF position.
NOTE:For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates coolertemperatures. Rotating the knob clockwise, into the red
area, indicates warmer temperatures.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser (located in front of the radiator), for an accumu-
lation of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Mode control allows you to choose
from several patterns of air distribu-
tion. You can select either a primary
mode, as identified by the symbols, or
a blend of two of these modes. The
closer the control is to a particular
mode, the more air distribution you
receive from that mode.

DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire’s manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger car tires must conform to Federal safety
requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may departsignificantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire’s ability to stop on
wet pavement, as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
