2012 DODGE CHALLENGER inflation pressure

•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the “TPM Telltale
Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure. The TPMS consists of the following components:
•Receiver module,
•Four TPM sensors, and
•TPM Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “TPM Telltale Light” will illuminate in the
instrument cluster, a “LOW TIRE” message will be
displayed and a chime will sound when tire pres-
sure is low in one or more of the four active road tires.
Should this occur, you should stop as soon as possible,
check the inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update and the “TPM Telltale Light” and “LOW TIRE”
message will turn off. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
320 STARTING AND OPERATING

Should this occur, you should stop as soon as possible
and inflate all of the tires with a low pressure condition
(those flashing in the EVIC graphic) to the vehicle’s
recommended cold placard pressure inflation value.
Once the system receives the updated tire pressures, the
system will automatically update, the graphic display in
the EVIC will stop flashing, and the “TPM Telltale Light”
will turn off. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

WARNING! (Continued)
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for the proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes

Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.

STARTING AND OPERATING 343

If the tire does not inflate to at least 26 psi (1.8 Bar)
pressure within 15 minutes:
•The tire is too badly damaged. Do not attempt to drive
the vehicle further. Call for assistance.
NOTE: If the tire becomes over-inflated, press the
Deflation Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
If the tire inflates to the recommended pressure or is at
least 26 psi (1.8 Bar) pressure within 15 minutes:
1. Press the Power Button (4) to turn off the TIREFIT kit.
2. Remove the Speed Limit sticker from the top of the
Sealant Bottle (1) and place the sticker on the instrument
panel.
3. Immediately disconnect the Sealant Hose (6) from the
valve stem, reinstall the cap on the fitting at the end of the hose, and place the TIREFIT kit in the vehicle storage
location. Quickly proceed to (D) “Drive Vehicle”.CAUTION!
•The metal end fitting from Power Plug (8) may get
hot after use, so it should be handled carefully.
•Failure to reinstall the cap on the fitting at the end
of the Sealant Hose (6) can result in sealant con-
tacting your skin, clothing, and the vehicle’s inte-
rior. It can also result in sealant contacting internal
TIREFIT kit components which may cause perma-
nent damage to the kit.
(D) Drive Vehicle:
Immediately after injecting sealant and inflating the tire,
drive the vehicle 5 miles (8 km) or 10 minutes to ensure
distribution of the TIREFIT Sealant within the tire. Do not
exceed 55 mph (88 km/h).
362 WHAT TO DO IN EMERGENCIES

WARNING!
TIREFIT is not a permanent flat tire repair. Have the
tire inspected and repaired or replaced after using
TIREFIT. Do not exceed 55 mph (88 km/h) until the
tire is repaired or replaced. Failure to follow this
warning can result in injuries that are serious or fatal
to you, your passengers, and others around you.
(E) After Driving:
Pull over to a safe location. Refer to “Whenever You Stop
to Use TIREFIT” before continuing.
1. Turn the Mode Select Knob (5) to the Air Mode
position.
2. Uncoil the power plug and insert the plug into the
vehicle’s 12 Volt power outlet.3. Uncoil the Air Pump Hose (7) (black in color) and
screw the fitting at the end of hose (7) onto the valve
stem.
4. Check the pressure in the tire by reading the Pressure
Gauge (3).
If tire pressure is less than 19 psi (1.3 Bar)
, the tire is too
badly damaged. Do not attempt to drive the vehicle
further. Call for assistance.
If the tire pressure is 19 psi (1.3 bar) or higher:
1. Press the Power Button (4) to turn on TIREFIT and
inflate the tire to the pressure indicated on the tire and
loading information label on the driver-side door open-
ing.
NOTE: If the tire becomes over-inflated, press the
Deflation Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
