2010 DODGE CHALLENGER warning light

turn off when the fault condition no longer exists. A
system fault can occur due to any of the following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles with Compact Spare
1. The compact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the pressure in the
compact spare tire.2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound and the “TPM Telltale Light” will turn ON.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on solid.
4. For each subsequent ignition switch cycle, a chime will
sound and the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the “TPM
Telltale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the four
active road tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.

STARTING AND OPERATING 309

Premium 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,
•Four TPM sensors,
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
•TPM Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “TPM 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. In addition, the EVIC will display one or
more low pressure messages (Left Front, Left Rear, Right
Front, Right Rear) for three seconds and a graphic
showing the pressure values of each tire with the low tire
pressure values flashing.
310 STARTING AND OPERATING

Check TPMS Warning
If a system fault is detected, the “TPM 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 aCHECK TPM SYSTEM message for three
seconds and then display dashes (- -) in place of the pressure
value to indicate which sensor is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “TPM Telltale Light” will no longer
flash, and the CHECK TPM SYSTEM message 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:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
312 STARTING AND OPERATING

Vehicles with Compact Spare
1. The compact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the pressure in the
compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the “TPM
Telltale Light” will remain ON and a chime will sound. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on solid. In
addition, the EVIC will display aCHECK TPM SYS-
TEM message for three seconds and then display dashes
(- -) in place of the pressure value. 4. For each subsequent ignition switch cycle, a chime will
sound, the “TPM Telltale Light” will flash on and off for
75 seconds and then remain on solid, and the EVIC will
display a
CHECK TPM SYSTEM message for three
seconds and then display dashes (- -) in place of the
pressure value.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPM Telltale Light” will turn OFF and the graphic in the
EVIC will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes above
15 mph (25 km/h) in order for the TPMS to receive this
information.

CAUTION! (Continued)
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

8. 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.
9. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
10. 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 authorized dealer or at a
service station.
11. 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.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.
Compact Spare Tire
The compact spare tire is for temporary emergency use
with radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
•Keep tire inflated to 60 psi (414 KPa) cold inflation
pressure.
•This tire is designed as an emergency spare only. Do
not exceed 50 mph (80 km/h) speed.
358 WHAT TO DO IN EMERGENCIES

WARNING!
The limited-use spare tires are for emergency use
only. Installation of this limited-use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold tire
inflation pressure listed on either your tire placard or
limited-use spare tire and wheel assembly. Replace
(or repair) the original tire at the first opportunity
and reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
Wheel Cover or Center Cap Installation — If
Equipped
NOTE:Do not attempt to install a center cap or wheel
cover on the compact spare. 1. Mount the road tire on the axle. For vehicles equipped
with wheel covers, perform Steps 2 and 3. For vehicles
equipped with center caps, proceed to Step 4.
2. Install two lug nuts on the mounting studs, which are
on each side of the stud that is in alignment with the
valve stem. 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.

WHAT TO DO IN EMERGENCIES 359

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Master Cylinder – Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the “MAX”
mark on the side of the master cylinder reservoir.Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the brake
pads wear. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
