2017 DODGE CHALLENGER fuel cap

Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Instrument Cluster Display •When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Understanding
Your Instrument Panel” for further information.
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 “Maintaining Your Ve-
hicle”. 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.

Speed Limit Warning Light — If Equipped
Red TelltaleLight What It Means
Speed Limit Warning Light
If the vehicle speed is greater than or equal to 75 mph (120 km/h), the Speed Warning telltale
will display in the instrument cluster display, and a chime will sound with a pop up warning
message.
Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow Telltale
Light What It Means
Engine Check/Malfunction Indicator 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 systems. The 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 key 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 vehicle 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 im-
mediate loss of power or severe catalytic converter damage. The vehicle should be serviced as
soon as possible if this occurs.

Loose Fuel Filler Cap Indicator Light — If Equipped
Yellow TelltaleLight What It Means
Loose Fuel Filler Cap Indicator Light — If Equipped
This light will illuminate when the fuel filler cap is loose. Properly close the filler cap to disen-
gage the light. If the light does not turn off, please see your authorized dealer.
LaneSense Indicator Light — If Equipped
Yellow Telltale
Light What It Means
LaneSense Indicator Light — If Equipped
The LaneSense system provides the driver with visual and steering torque warnings when the
vehicle starts to drift out of its lane unintentionally without the use of a turn signal.
•
When the LaneSense system senses a lane drift situation, the LaneSense indicator changes
from solid green to solid yellow.
• When the LaneSense system senses the lane has been approached and is in a lane departure
situation, the LaneSense indicator changes from solid white/green to flashing yellow.
Refer to “LaneSense - If Equipped in “Understanding The Features Of Your Vehicle” for further
information.

CAUTION!(Continued)
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 an authorized dealership to have your sensor
function checked.
• After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the TPM 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.

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
• Keep the trunk closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
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.
Fuel Filler Cap
368 STARTING AND OPERATING

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being 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.
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.
• 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
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. Refer to “Onboard Diagnostic
System” in “Maintaining Your Vehicle” for further infor-
mation.
