2008 CHRYSLER 300 C flat tire

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 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.
•After 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:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving 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.
•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 Tire Pressure Moni-
toring Telltale light.

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System — 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:
•Receiver Module
•4 Tire Pressure Monitoring Sensors
•Tire 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

•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block or\4chock\4the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR4. 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
\25
Do not attempt to tow a trailer while using a compact
spare tire.
\25Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires–General Information” in this section for infor-
mation on tire pressures and for proper tire inflation
procedures.
\25Also, check the trailer tires for proper tire inflation
pressures before trailer usage.

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.3. If equipped with steel wheels, do not remove the
wheel cover at this time. If equipped with aluminum
wheels where the center cap covers the lug nuts, use the
lug wrench to pry the center cap off carefully before
raising the vehicle.

398 WHAT TO DO IN EMERGENCIES

WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with the metal edges
and retention teeth.
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.

6. Raise the vehicle just enough to remove the flat tire
and install the spare tire.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
7. Remove the lug nuts, wheel cover (if equipped), and
tire. Remove the cover by hand. Do not pry it off.
8. Mount the spare tire.
NOTE:For vehicles so equipped, do not attempt to
install a center cap or wheel cover on the compact spare.
However, when reinstalling the road tire, follow the
procedure under “Wheel Cover or Center Cap Installa-
tion” in place of the remaining steps in this procedure.9. Install the lug nuts with the cone shaped end of the
nut toward the wheel. Lightly tighten the lug nuts. To
avoid the risk of forcing the vehicle off the jack, do not
tighten the lug nuts fully until the vehicle is lowered to
the ground.
10. Lower the vehicle to the ground by turning the jack
handle counter-clockwise.
11. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. The
correct tightness of each lug nut is 100 ft/lb. (135 N. m).
If in doubt about the correct tightness, have them
checked with a torque wrench by your dealer or at a
service station.
12. Stow the jack, tools, and flat tire. Make sure the base
of the jack faces the rear of the vehicle before tightening
down the fastener.
