run flat CHRYSLER 300 2014 2.G Owners Manual

Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition is in the START
or ON/RUN position. If the ignition is in the OFF
position or in the ACC position, the air bag system is not
on and the air bags will not inflate.The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Air Bag Warning
Light in the instrument panel for approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Air Bag Warning Light will turn off. If the
ORC detects a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

WARNING!(Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
air bag system service. If your seat, including your
trim cover and cushion, needs to be serviced in any
way (including removal or loosening/tightening of
seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved
seat accessories may be used. If it is necessary to
modify the air bag system for persons with dis-
abilities, contact your authorized dealer.
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free. If any of
the following occurs, have an authorized dealer service
the air bag system immediately.
• The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition is first
cycled to the ON/RUN.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.

STARTING AND OPERATING 363

Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced imme-
diately with another Run Flat tire of identical size and
service description (Load Index and Speed Code).
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (spring,
summer, fall and winter). Traction levels may vary be-
tween different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with summer tires, be
aware these tires are not designed for winter or cold
driving conditions. For more information, contact a au-
thorized dealer. Summer tires do not contain the all
season designation or mountain/snowflake symbol on
the tire sidewall.
Use summer tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
Snow Tires
Some areas of the country require the use of snow tires
during the winter. Snow tires can be identified by a
mountain/snowflake symbol on the tire sidewall.
430 STARTING AND OPERATING

If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of four; failure to do so may adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has limited
driving capabilities and needs to be replaced immedi-
ately. A Run Flat tire is not repairable.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more infor-
mation.

504 WHAT TO DO IN EMERGENCIES

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Manual
Park Release” or “Shift Lever Override” in this section for
instructions on shifting the transmission out of PARK for
towing.CAUTION!
•Do not use sling type equipment when towing.
Damage to the fascia will occur.
• When securing the vehicle to a flatbed truck, do not
attach to the front or rear suspension components.
Damage to your vehicle may result from improper
towing.
• Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
mission may result.
• The ignition switch must be in the ON/RUN posi-
tion, not in the OFF or ACC position.
• If the vehicle being towed requires steering, the
ignition switch must be in the ON/RUN position,
not in the OFF or ACC position.
• The manufacturer does not recommend towing this
vehicle using a tow dolly. Vehicle damage may
occur.

WHAT TO DO IN EMERGENCIES 505

All Wheel Drive (AWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If the transmission and drivetrain are operable, vehicles
equipped with AWD can also be towed with the ignition
in the ON/RUN position, the transmission in NEUTRAL
(not in PARK!), and the rear wheels OFF the ground with
no limitation on speed or distance. Since the ignition
MUST be in the ON/RUN position to tow in this manner,
AWD vehicles must be towed with ALL FOUR wheels
OFF the ground (e.g. on a flatbed truck) if the Key Fob is
unavailable.
CAUTION!
•Towing this vehicle using any other method could
result in extensive damage to the transfer case
and/or transmission.
• Damage from improper towing is not covered un-
der the New Vehicle Limited Warranty.
Rear-Wheel Drive (RWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, this vehicle may be towed (with rear
wheels on the ground) under the following conditions:
• The transmission must be in NEUTRAL.
• The towing speed must not exceed 30 mph (48 km/h).
