2008 DODGE MAGNUM flat tire

pressure will also increase as the vehicle is driven - this
is normal and there should be no adjustment for this
increased pressure.
²The TPM System will warn the driver of a low tire
pressure if the tire pressure falls below the low-
pressure warning limit for any reason, including low
temperature effects and natural pressure loss through
the tire.
²The TPM System will continue to warn the driver of
low tire pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above
the recommended cold placard pressure. Once the low
tire pressure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the tire
pressure to the recommended cold placard pressure in
order for the Tire Pressure Monitoring Telltale Light to
turn off. The system will automatically update and the
Tire Pressure Monitoring Telltale Light will turn offonce the system receives the updated tire pressures.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (25 km/h) in order for the TPMS to
receive this information.
þFor example, your vehicle may have a recom-
mended cold (parked for more than 3 hours) placard
pressure of 30 psi (207 kPa). If the ambient tempera-
ture is 68ÉF (20ÉC) and the measured tire pressure is
27 psi (186 kPa), a temperature drop to 20ÉF (-7ÉC)
will decrease the tire pressure to approximately 26
psi (179 kPa). This tire pressure is sufficiently low
enough to turn ON the Tire Pressure Monitoring
Telltale light. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa),
but the Tire Pressure Monitoring Telltale Light will
still be ON. In this situation, the Tire Pressure
Monitoring Telltale Light will turn OFF only after
the tires are inflated to the vehicle's recommended
cold placard pressure value.

CAUTION!
²The 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 us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
²After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's handling and
stopping ability.
²The 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 Tire Pressure Moni-
toring Telltale light.
324 STARTING AND OPERATING

²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System Ð If Equipped
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:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale LightThe matching full size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The
matching full size spare can be used in place of any of the
four road tires. The TPMS will only monitor the pressure
in the full size spare when it is used in place of a road tire.
Otherwise, a spare with a pressure below the low-
pressure limit will not cause the Tire Pressure Monitoring
Telltale Light to illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and a chime
will sound when tire pressure 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 pres-
sures, the system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off. The

Should this occur, you should stop as soon as possible,
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle's recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the Tire Pressure Monitoring Telltale Light will
turn off. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
Check TPMS Warning
If a system fault is detected, the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and then
remain on solid. The system fault will also sound a
chime. In addition, the EVIC will display a9CHECK TPM
SYSTEM9message for 3 seconds and then display dashes
(- -) in place of the pressure value to indicate which
sensor is not being received.If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and the9CHECK TPM SYS-
TEM9message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:

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 Ð Tires
þ
Do not attempt to tow a trailer while using a compact
spare tire.
þProper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
ªTires±General Informationº in this section for infor-
mation on tire pressures and for proper tire inflation
procedures.
þAlso, check the trailer tires for proper tire inflation
pressures before trailer usage.
þCheck for signs of tire wear or visible tire damage
before towing a trailer. Refer to ªTires±General Infor-
mationº in this section for information on tread wear
indicators and for the proper inspection procedure.
þWhen replacing tires, refer to ªTires±General Informa-
tionº in this section for information on replacement
tires and 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 Ð Trailer Brakes
þ
Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
þAn electronically actuated trailer brake controller is
required when towing a trailer with electronically

6. Remove the fastener securing the jack.WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
Jacking and Changing a Tire
1. Block the wheel diagonally
opposite the flat tire. Passengers
should not remain in the vehicle
when the vehicle is being jacked.
2. Remove the spare tire, jack, and lug wrench.

4. Before raising the vehicle, use the lug wrench to
loosen, but not remove, the lug nuts on the wheel with
the flat tire. Turn the lug nuts counter-clockwise one turn
while the wheel is still on the ground.5. Place the jack underneath the lift area that is closest to
the flat tire. Turn the jack screw clockwise to firmly
engage the jack saddle with the lift area of the sill flange.
