2008 DODGE MAGNUM SRT Owners Manual

WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than 35
mph (55 km/h) when you are stuck, and don’t let
anyone near a spinning wheel, no matter what the
speed.
TOWING A DISABLED VEHICLE
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing without the ignition key is
with a flat-bed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
Towing This Vehicle Behind Another Vehicle (Flat
Towing With All Four Wheels On The Ground)
Flat towing of vehicles equipped with an automatic
transmission, is only permitted within the following
limitations
With The Ignition Key
Your vehicle may be towed under the following condi-
tions: The shift lever must be in NEUTRAL, the distance
to be traveled must not exceed 30 mi (48 km), and the
towing speed must not exceed 30 mph (48 km/h).
Exceeding these towing limits may cause a transmission
geartrain failure. If the transmission is not operative or if
the vehicle is to be towed more than 30 mi (48 km), the
vehicle must be transported using a flat-bed truck.

result.
•Do not tow the vehicle from the rear. Damage to
the rear sheet metal and fascia will occur.
•Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
mission may result.If you must use the accessories (wipers, defrosters, etc.)
while being towed, the key must be in the ON position,

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the “MIL” on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
If the “MIL” is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.For states that require an I/M (Inspection and
Maintenance), this check verifies the MIL is func-
tioning and is not on when the engine is running,
and that the OBD II system is ready for testing.
Normally, the OBD system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced or recently had a dead battery or had a battery
replacement. If the OBD II system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
