2009 CHRYSLER 300 C tire size

To Activate
Push and release the ON/OFF button located
on the end of the Electronic Speed Control
lever. The indicator light in the instrument
cluster will illuminate to show that the speed
control system is on. To turn the system off, push and
release the ON/OFF button again. The system and the
indicator light will turn off.
WARNING!
Leaving the Electronic Speed Control system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have an accident. Always
leave the Electronic Speed Control system off when
you are not using it.
To Set At A Desired Speed
When the vehicle reaches the speed desired, push the
lever downward to SET DECEL and release. Remove
your foot from the accelerator pedal and the vehicle will
operate at the selected speed.
NOTE:
•Electronic Speed Control will only function in 3rd, 4th,
or 5th gear when in the Autostickmode (if
equipped).
•The Electronic Speed Control may not engage if a
different size tire is installed on one wheel, such as the
compact spare tire.

21. Electronic Throttle Control (ETC) Light
This light will turn on briefly as a bulb check
when the ignition switch is turned ON. This
light will also turn on while the engine is
running if there is a problem with the Elec-
tronic Throttle Control (ETC) system.
If the light comes on while the engine is running, safely
bring the vehicle to a complete stop as soon as possible,
place the shift lever in PARK, and cycle the ignition key.
The light should turn off. If the light remains lit with the
engine running, your vehicle will usually be drivable.
However, see an authorized dealer for service as soon as
possible.
If the light is flashing when the engine is running,
immediate service is required. In this case, you may
experience reduced performance, an elevated/rough idle
or engine stall, and your vehicle may require towing.Also, have the system checked by an authorized dealer if
the light does not come on during starting.
22. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
218 UNDERSTANDING YOUR INSTRUMENT PANEL

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 opera-
tion or sensor damage may result when using re-
placement 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.
23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essentialelectrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
24. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when
the key is in the ON position before engine start. If the
MIL does not come on when turning the key from LOCK
to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL

CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the rear wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when the roads are
slushy.
334 STARTING AND OPERATING

WARNING!
•The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
(Continued)
WARNING! (Continued)
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user’s safety or
the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
342 STARTING AND OPERATING

NOTE:
•The ESP/TCS Indicator Light and the ESP/BAS Mal-
function Indicator Light will turn on momentarily
each time the ignition switch is turned ON.
•Each time the ignition switch is turned ON, the ESP
system will be on even if it was turned off previously.
•The ESP control system will make buzzing or clicking
sounds when it is active. This is NORMAL; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.

•P (Passenger) - Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European-Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letterPis absent from this tire
size designation. Example: 215/65R15 96H.
•LT (Light Truck) - Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are high-pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
•High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.
