2008 DODGE CHARGER fuel

NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler cap door
reinforcement.CAUTION!
²Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap).
²A poorly fitting gas cap could let impurities into
the fuel system.
²A poorly fitting gas cap may cause the Malfunc-
tion Indicator Light to turn on.
²To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling. When the fuel
nozzle ªclicksº or shuts off, the fuel tank is full.

324 STARTING AND OPERATING

WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel to the vehicle when the engine is
running.
²A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
²Tighten the gas cap until you hear a ªclickingº sound.
This is an indication that the gas cap is tightened
properly. The Malfunction Indicator Light in the in-
strument cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap is tight-
ened each time the vehicle is refueled.
²When the fuel nozzle ªclicksº or shuts off, the fuel
tank is full.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
ªCheck Gascapº message will display in the Electronic
Vehicle Information Center (EVIC) Ð if equipped. If this
occurs, tighten the fuel filler cap properly and press the
odometer reset 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 Malfunction Indicator Light (MIL).
Refer to ªOnboard Diagnostic Systemº in Section 7 of this
manual for more information.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Towing Tips Ð Automatic Transmission
The ªDº range can be selected when towing. However, if
frequent shifting occurs while in this range, the ª3º range
should be selected.
NOTE:Using the ª3º range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the auto-
matic transamission fluid and filter according to the
interval specified for ªpolice, taxi, fleet, or frequent trailer
towingº in the ªMaintenance Scheduleº in this manual.
Towing Tips Ð Electronic Speed Control (If
Equipped)
þ
Don't use in hilly terrain or with heavy loads.
þWhen using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
þUse speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips Ð Autostickt(If Equipped)
þ
For vehicles equipped with Autostick.tBy using the
Autosticktmodes, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose ª4º if the desired
speed can be maintained. Choose ª3º or ª2º if needed
to maintain the desired speed.

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 dealer or at a
service station.
7. For vehicles equipped with center caps, install the
center cap by hand. Do not use a hammer or excessive
force to install the center cap.
8. Stow the jack, tools, and spare 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.
JUMP-STARTING PROCEDURES
WARNING!
²Take care to avoid the radiator cooling fan whenever the hood is raised.
It can start anytime the ignition switch is on. You can be hurt by the fan.
²Do not attempt to push or tow your vehicle to get it started. Vehicles
equipped with an automatic transmission cannot be started this way.
Unburned fuel could enter the catalytic converter and once the engine
has started, ignite and damage the converter and vehicle. If the vehicle
has a discharged battery, booster cables may be used to obtain a start
from another vehicle. This type of start can be dangerous if done
improperly, so follow this procedure carefully.
²Battery fluid is a corrosive acid solution; do not allow battery fluid to
contact eyes, skin, or clothing. Don't lean over battery when attaching
clamps or allow the clamps to touch each other. If acid splashes in eyes
or on skin, flush contaminated area immediately with large quantities of
water.
²A battery generates hydrogen gas, which is flammable and explosive.
Keep flame or spark away from the vent holes.
²Do not use a booster battery or any other booster source with an output
that exceeds 12 volts.
²The battery in this vehicle has a vent hose that should not be discon-
nected and should only be replaced with a battery of the same type
(vented).

364 MAINTAINING YOUR VEHICLE

ONBOARD DIAGNOSTIC SYSTEM Ð 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 ªMalfunction Indicator Light.º 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 dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emission
control system. It could also affect fuel economy and
driveability. The vehicle must be serviced before any
emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur. Im-
mediate 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
ªCheck Gascapº message will display in the Electronic
Vehicle Information Center (EVIC) Ð if equipped. If this
occurs, tighten the fuel filler cap properly and press the
370 MAINTAINING YOUR VEHICLE

odometer reset 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 Malfunction Indicator Light (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, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Light)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD 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 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.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
