Look for the Equipment Identification Sticker
[i] to identify your vehicle's Axle Ratio. If you are unable to determine your vehicles axle ratio, assume you have the numerically lower ratio and can tow the lesser of these ratings.

While it is not listed in the charts, tongue weight [i] is also an important consideration. The recommended tongue weight is between 10 & 15% of the trailer weight. However, the maximum tongue weight on Class III (The bumper ball) is limited to 500 lbs, and Class IV (The receiver hitch) to 1200 lbs.
This requirement overrides any recommended GTW rating, between 10% and 15% of gross trailer weight (GTW). Additionally, the GAWRs and GVWRs should never be exceeded.
Secure payload to prevent shifting of weight during braking, acceleration, cornering, or bumps, etc. If loads shift during dynamic conditions, load distribution could change resulting in an unsafe condition, or could exceed limits of recommended tongue weight. Incorrect tongue weight could result in increased yaw or vehicle instability. A negative tongue weight could unload the rear suspension of the tow vehicle decreasing vehicle stability. Negative tongue weight could cause the trailer to squat and potentially become disengaged from the tow vehicle resulting in a runaway trailer condition.
Towing capacities may vary. Consult your dealer for full details on the towing capabilities of the vehicle.
