2015 DODGE CHALLENGER inflation pressure

wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph on
“Tread Wear Indicator.” Refer to the Tire and Loading
Information placard or the Vehicle Certification Label for
the size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the original
equipment tire sidewall. See the Tire Sizing Chart ex-
ample found in the Tire Safety Information section of this
manual for more information relating to the Load Index
and Speed Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.

414 STARTING AND OPERATING

The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (6.5°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation pressure must
not exceed the maximum inflation pressure molded into
the tire sidewall. Refer to “Tires – General Information”
in “Starting and Operating” for information on how to
properly inflate the vehicle’s tires. The tire pressure will
also increase as the vehicle is driven - this is normal and
there should be no adjustment for this increased pres-
sure.
The TPMS 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.
The TPMS 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 warn-
ing (Tire Pressure Monitoring [TPM] Telltale Light) illu-
minates, you must increase the tire pressure to the
recommended cold placard pressure in order for the
“TPM Telltale Light” to turn off. The system will auto-
matically update and the “TPM Telltale Light” will turn
off once the system receives the updated tire pressures.
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.
418 STARTING AND OPERATING

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 “TPM Telltale Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
420 STARTING AND OPERATING

WARNING!(Continued)
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. Max loading as defined on the “Tire and Loading
Information” placard.
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.
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.

STARTING AND OPERATING 443

NOTE:If the Mode Select Knob (5) is on Air Mode and
the pump is operating, air will dispense from the Air
Pump Hose (7) only, not the Sealant Hose (6).
If the sealant (white fluid) does flow through the
Sealant Hose (6):
1. Continue to operate the pump until sealant is no
longer flowing through hose (typically takes 30 - 70
seconds). As the sealant flows through the Sealant
Hose (6), the Pressure Gauge (3) can read as high as 70
psi (4.8 Bar). The Pressure Gauge (3) will decrease
quickly from approximately 70 psi (4.8 Bar) to the
actual tire pressure when the Sealant Bottle (1) is
empty.
2. The pump will start to inject air into the tire immedi-
ately after the Sealant Bottle (1) is empty. Continue to
operate the pump and inflate the tire to the pressure
indicated on the tire pressure label on the driver-side
latch pillar (recommended pressure). Check the tire
pressure by looking at the Pressure Gauge (3).
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 Defla-
tion 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 Tire Service
Kit.
2. Remove the Speed Limit sticker from the top of the
Sealant Bottle (1) and place the sticker on the instru-
ment panel.

WHAT TO DO IN EMERGENCIES 461

(E) After Driving:
Pull over to a safe location. Refer to “Whenever You Stop
to Use Tire Service Kit” before continuing.
1. Push in the Mode Select Knob (5) and turn 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 Tire Service Kit
and inflate the tire to the pressure indicated on the tire
and loading information label on the driver-side door
opening.
NOTE:If the tire becomes over-inflated, press the Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
2. Disconnect the Tire Service Kit from the valve stem,
reinstall the cap on the valve stem and unplug from 12
Volt outlet.
3. Place the Tire Service Kit in its proper storage area in
the vehicle.
4. Have the tire inspected and repaired or replaced at the
earliest opportunity at an authorized dealer or tire
service center.
