Ram Trucks 2012 С/V - User Guide - Manual (Page 85)

• Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue each time the vehicle is
restarted as long as the malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle, to ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
NOTE: Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the outside
temperature is 32°F (0°C), then the cold tire inflation pressure should be increased by
3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this outside
temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels.
TPMS pressures and warning have been established for the tire size equipped
on your vehicle. Undesirable system operation or sensor damage may result
when using replacement equipment that is not of the same size, type, and/or
style. Aftermarket wheels can cause sensor damage. Do not use tire sealant
from a can, or balance beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on or flashes continuously while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for service.
• We recommend that you do not operate the vehicle or engine damage will occur.
Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned
by steam or boiling coolant. You may want to call an authorized service center
for service if your vehicle overheats.
