Loose Fuel Filler Cap Message; Vehicle Loading; Certification Label - Jeep WRANGLER 2020 Owner's Manual

264 STARTING AND OPERATING
CAUTION!
Damage to the fuel system or emission

control system could result from using an
improper fuel filler cap. A poorly fitting cap
could let impurities into the fuel system.
Also, a poorly fitting aftermarket cap can
cause the "Malfunction Indicator Light
(MIL)" to illuminate, due to fuel vapors
escaping from the system.
To avoid fuel spillage and overfilling, do not

"top off" the fuel tank after filling.
NOTE:
When the fuel nozzle "clicks" or shuts off, the

fuel tank is full.
Tighten the fuel filler cap about 1/4 turn until

you hear one click. This is an indication that
the cap is properly tightened.
If the fuel filler cap is not tightened properly,

the MIL will come on. Be sure the cap is tight-
ened every time the vehicle is refueled.

Loose Fuel Filler Cap Message

After fuel has been added, the vehicle diagnostic
system can determine if the fuel filler cap is possibly
loose, improperly installed, or damaged. If the
system detects a malfunction, the "gASCAP"
message will display in the odometer display.
Tighten the gas cap until a "clicking" sound is heard.
This is an indication that the gas cap is properly
tightened. Push the odometer reset button to turn
the message off. If the problem persists, the
message will appear the next time the vehicle is
started. This might indicate a damaged cap. If the
problem is detected twice in a row, the system will
turn on the MIL. Resolving the problem will turn the
MIL off.

VEHICLE LOADING

Certification Label

As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side
door or pillar.
This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), Gross Axle Weight Rating (GAWR) front
and rear, and Vehicle Identification Number
(VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month,
Day and Hour of manufacture. The bar code that
appears on the bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear axle
systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not
exceeded.
Payload
The payload of a vehicle is defined as the
allowable load weight a truck can carry,
including the weight of the driver, all
passengers, options and cargo.
