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:
•
Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
•
If the gas cap is not tightened properly, the MIL may
come on. Be sure the gas cap is tightened every
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 “Check Fuel Cap” message will be displayed in the
instrument cluster display
page 69. Tighten the fuel
filler cap until a “clicking” sound is heard. This is an
indication that the fuel filler cap is properly tightened.
If the problem continues, the message will appear the
next time the vehicle is started. See an authorized
dealer as soon as possible.
VEHICLE LOADING
As required by National Highway Traffic Safety Adminis-
tration regulations, your vehicle has a certification label
affixed to the driver's side door or B-pillar.
If seats are removed for carrying cargo, do not exceed
the specified GVWR and GAWR.
VEHICLE CERTIFICATION LABEL
Your vehicle has a Vehicle Certification Label affixed to
the driver’s 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 and rear
•
Vehicle Identification Number (VIN)
•
Type of vehicle
•
Month, Day, and Hour (MDH) of manufacture
The bar code allows a computer scanner to read the
VIN.
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
GROSS AXLE WEIGHT RATING
(GAWR)
The GAWR is the maximum capacity of the front and
rear axles. Distribute the load over the front and rear
axles evenly. Make sure that you do not exceed either
front or rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose con-
trol of the vehicle and have a collision.
TIRE SIZE
The tire size on the Vehicle Certification Label repre-
sents the actual tire size on your vehicle. Replacement
tires must be equal to the load capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire size
listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your vehicle
for all loading conditions up to full Gross Axle Weight
Rating (GAWR).
