LOAD CARRYING
PRECAUTIONS
Keep your loaded vehicle weightwithin its design rating capability,with or without a trailer. Properlyloading your vehicle providesmaximum return of vehicle designperformance. Before you load yourvehicle, become familiar with thefollowing terms for determiningyour vehicle’s weight rating, withor without a trailer, from thevehicle’s Tire and LoadingInformation label or SafetyCompliance Certification label.
WARNING: Vehicles witha higher center of gravity (utilityand four-wheel drive vehicles)handle differently than vehicleswith a lower center of gravity(passenger cars). Avoid sharpturns, excessive speed andabrupt steering in these vehicles.Failure to drive cautiouslyincreases the risk of losingcontrol of your vehicle, vehiclerollover, personal injury anddeath.
WARNING: Theappropriate loading capacity ofyour vehicle can be limited eitherby volume capacity (how muchspace is available) or by payloadcapacity (how much weight thevehicle should carry). Once youhave reached the maximum
payload of your vehicle, do notadd more cargo, even if there isspace available. Overloading orimproperly loading your vehiclecan contribute to loss of vehiclecontrol and vehicle rollover.
WARNING: Exceeding theSafety Compliance Certificationlabel vehicle weight limits canadversely affect theperformance and handling ofyour vehicle, cause vehicledamage and can result in theloss of control of your vehicle,serious personal injury or death.
WARNING: Do not usereplacement tires with lowerload carrying capacities than the
original tires because they maylower your vehicle's GVWR andGAWR limitations. Replacementtires with a higher limit than theoriginal tires do not increase theGVWR and GAWR limitations.
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Exceeding anyvehicle weight rating canadversely affect theperformance and handling ofyour vehicle, cause vehicledamage and can result in theloss of control of your vehicle,serious personal injury or death.

WARNING: When loadingthe roof racks, we recommendyou evenly distribute the load,as well as maintain a low centerof gravity. Loaded vehicles, withhigher centers of gravity, mayhandle differently than unloadedvehicles. Take extra precautions,such as slower speeds andincreased stopping distance,when driving a heavily loadedvehicle.
The gross combined weight mustnever exceed the Gross CombinedWeight Rating.
USING A SLIDE-IN CAMPER
For information regarding the use ofslide-in campers, consult the TruckCamper Loading document supplied withyour vehicle.
LOCATING THE SAFETY
COMPLIANCE CERTIFICATION
LABELS
Safety Compliance Certification LabelExample:
The Safety Compliance Certification labelis located on the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver seating position.
WHAT IS THE GROSS AXLE
WEIGHT RATING
GAWR (Gross Axle WeightRating)
GAWR is the maximum allowableweight that a single axle (front orrear) can carry. These numbersare on the Safety ComplianceCertification label.
WHAT IS THE GROSS VEHICLE
WEIGHT RATING
GVWR is the maximum allowableweight of the fully loaded vehicle.This includes all options,equipment, passengers and cargo.It appears on the SafetyCompliance Certification label.
WHAT IS THE GROSS
COMBINED WEIGHT RATING
Gross Combined Weight Rating(GCWR) is the maximumallowable weight of the vehicleand the loaded trailer, includingall cargo and passengers, that thevehicle can handle without riskingdamage. (Important: The towingvehicle’s braking system is ratedfor operation at Gross Vehicle
Weight Rating, not at GrossCombined Weight Rating.)
