2018 DODGE CHALLENGER fuel cap

3. Speedometer•Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the Keyless Push Button Ignition is in the
ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H,” turn the engine off immediately and call an
authorized dealer for service.
NOTE: The hard telltales will illuminate for a bulb check
when the ignition is first cycled.

— Electric Power Steering Fault Warning Light
This light will turn on when there’s a fault with the EPS
(Electric Power Steering) system. Refer to “Power Steering”
in “Starting And Operating” for further information.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
— Door Open Warning Light
This indicator will illuminate when a door is ajar/open and
not fully closed.
NOTE:If the vehicle is moving, there will also be a single
chime.
— Trunk Open Warning Light
This indicator will illuminate when the trunk is open and
not fully closed.
Yellow Warning Lights
— Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control sys-
tems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the ve-
hicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
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.

This telltale will turn on to indicate a fault in the Forward
Collision Warning System. Contact your local authorized
dealer for service.
Refer to Forward Collision Warning (FCW) inSafety for
further information.
— Loose Fuel Filler Cap Warning Light — If
Equipped
This warning light will illuminate when the fuel filler cap
is loose. Properly close the filler cap to disengage the light.
If the light does not turn off, please see an authorized
dealer.
— Service AWD Warning Light — If Equipped
This telltale will turn on to indicate the All Wheel Drive
(AWD) system is not functioning properly and that service
is required. Contact your authorized dealer.
— Service Adaptive Cruise Control Warning

CAUTION!(Continued)
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to your authorized dealer to have your sensor func-
tion checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure. •
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE: It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.

STARTING AND OPERATING 195

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door on the left
side of the vehicle. Use a finger to pull open the door. If the
gas cap is lost or damaged, be sure the replacement cap is
for use with this vehicle.
NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the “Malfunction Indicator Light” to
turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
• A poorly fitting fuel filler cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the “Mal-
function Indicator Light (MIL)” to turn on.

Fuel Filler Cap
250 STARTING AND OPERATING

CAUTION!(Continued)
•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.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• 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 turn on
if the gas cap is not secured properly. Make sure that the
gas cap is tightened each time the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the instrument
cluster. If this occurs, tighten the fuel filler cap properly
and press the Trip Odometer button to turn off the mes-
sage. 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.
VEHICLE LOADING
The load carrying capacity of your vehicle is shown on the
“Vehicle Certification Label”. This information should be
used for passenger and luggage loading as indicated.
Do not exceed the specified Gross Vehicle Weight Rating
(GVWR) or the Gross Axle Weight Rating (GAWR).
Vehicle Certification Label
Your vehicle has a Vehicle Certification Label affixed to the
drivers side B-Pillar or the rear of the driver ’s door.
The label contains the following information:
•
Name of manufacturer
• Month and year of manufacture
• Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
