2008 CHRYSLER 300 SRT fuel cap

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 EVIC.
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 Malfunction Indicator Light (MIL).
(See page 387 for more information.)
7. Tachometer
The red segments indicate the maximum permissible
engine revolutions per minute (RPM x 1000) for each gear
range. Ease up on the accelerator before reaching the red
area.8. Engine Temperature Warning Light
This light will turn on and a single chime will
sound to warn of an overheated engine condition.
When this light turns on, the engine temperature
is critically hot. The vehicle should be turned OFF
immediately and serviced as soon as possible. (See page
371 for more information.)
9. Anti-Lock Brake Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if the BRAKE warning light is not on.

23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should turn on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on, or turns on while
driving, turn off some of the vehicle’s non-essential
electrical devices (i.e., radio) or slightly increase engine
speed (if at idle). If the light remains on, it means that the
charging system is experiencing a problem. See your
local authorized dealer to obtain service immediately.
24. Malfunction Indicator Light (MIL)
This light 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 OFF 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
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
The MIL flashes to alert you to serious conditions that
could lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs. (See page 387 for more
information.)
25. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle, and shut OFF the engine as soon as possible. A
single chime will sound when this light turns on.

•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Keep the trunk/liftgate closed when driving your
vehicle to prevent carbon monoxide and other poison-
ous exhaust gases from entering the vehicle.

Fuel Filler Cap (Gas Cap)
The gas cap is located behind the fuel filler door on the
left side of the vehicle. Push in on the left side (near the
edge) of the fuel filler door to access the fuel filler cap. If
the gas cap is lost or damaged, be sure the replacement
cap is for use with this vehicle.Fuel Filler Door

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

WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
•A 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:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turnon if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
