Gross Vehicle Mass (GVM)
The maximum laden mass of a motor vehicle which includes passengers, luggage, cargo, any accessories fitted and towball download.

Kerb Mass
The unladen mass of vehicle with full fuel, excludes any accessories fitted and tray body for Cab Chassis vehicles.

Gross Combined Mass (GCM)
The rated maximum laden mass of the vehicle and towed object combined.

Gross Trailer Mass (GTM)
The mass transmitted to the ground by the ‘Axle’ or ‘Axles’ of the trailer when coupled to a drawing vehicle and carrying its maximum load approximately uniformly distributed over the load bearing area.

Aggregate Trailer Mass (ATM)
The total mass of the trailer when carrying the maximum load recommended by the trailer manufacturer. This includes the Towball Download imposed onto towbar tongue.

Payload
Payload (or Carry Capacity) is the GVM minus the Kerb Mass. The Kerb Mass does not include passengers, luggage, cargo, any accessories fitted or any Towball Download (as appropriate). Payload is distributed across both the front and rear axles.

Gross Axle Weight Rating (GAWR)
The Gross Axle Weight Rating or Axle Capacity is the maximum permitted axle weight that can be carried. The axle capacities (in particular the rear) must be considered when a trailer is attached.

Towing Capacity Unbraked
The Unbraked Towing Capacity is the maximum allowable ATM of a trailer which is not fitted with brakes.

Towing Capacity Braked
The Braked Towing Capacity is the maximum allowable ATM of a trailer which is fitted with brakes.

Towball Download
The Towball Download is the amount of mass that is applied downwards on the towball. Towball Download acts on the vehicle and must be considered when ensuring the GVM or axle capacities are not exceeded.

Towing a trailer will place additional loads on your vehicle’s engine, drive train, steering, braking and other systems. The towing of a trailer will exaggerate other conditions such as sway caused by crosswinds, rough road surfaces or passing trucks.

Your driving style and speed must be adjusted according to the circumstances. Before towing a trailer, see your Nissan Dealer for an explanation about the proper use of towing equipment.

Operating precautions

• Avoid towing a trailer during the break-in period.
• Before driving, make sure that the lighting system of the trailer works properly.
• Observe the legal maximum speeds for trailer operation.
• Avoid abrupt starts, accelerations and stops.
• Avoid sharp turns and lane changes.
• Always drive your vehicle at a moderate speed.
• Follow the trailer manufacturer’s instructions.

• Choose proper coupling devices (trailer hitch, safety chain, roof carrier, etc.) for your vehicle and trailer. These devices are available from your Nissan Dealer where you can also obtain more detailed information about trailer towing.
• Never allow the total trailer load (trailer weight plus its cargo weight) to exceed the maximum set for the vehicle and the coupling device. See your Nissan Dealer for more information.
• The trailer must be loaded so that heavy goods are placed over the axle. The maximum allowable vertical load on the trailer hitch must not be exceeded.
• Have your vehicle serviced more often than the intervals specified in a separate maintenance booklet.
• Trailer towing requires more fuel than under normal circumstances because of a considerable increase in traction power and resistance.
• While towing a trailer, check the engine coolant temperature indicator to prevent the vehicle from overheating.

Maximum load limits (for Australia and New Zealand)
Y62 Patrol example only

Maximum trailer loads (including tyres and other loaded equipment):

1. Never allow the total trailer load to exceed:
   • The maximum 750 kg (1,654 lb) for a trailer without brakes‡.
   • The maximum 3,500 kg (7,718 lb) for a trailer with brakes‡.
2. The trailer load must not exceed the following three values even if it does not exceed the maximum permissible trailer loads:
   • Towing capacity displayed on a towbar.
   • Trailer gross mass marked on a coupling body.
   • Gross Combined Mass rating of the towing vehicle.

The maximum trailer load which can be towed by your vehicle depends on the towing equipment fitted to the vehicle. Therefore, it is important to not only have the correct equipment fitted but also to use it correctly. Towing loads greater than the value specified for your vehicle or using towing equipment which is not provided by Nissan could seriously affect the handling and/or performance of your vehicle. Vehicle damage resulting from improper towing procedures is not covered by Nissan warranties. Information on trailer towing and the required equipment should be obtained from your Nissan Dealer.

Maximum towball download

The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it carries the coupler/hitch assembly. Knowledge of the trailer towball download is critical as it can have a significant effect on the handling and capacity of the tow vehicle. Refer to your vehicle owner’s manual to view the maximum conventional trailer towball download listed for your vehicle.

Towball download is the amount of downward pressure exerted onto the towball. Keep the towball download around 10% of the total trailer weight. DO NOT exceed the maximum towball download specification. If the towball
download is less or more than 10% of the Gross Trailer Mass, you should rearrange the cargo in the trailer to meet the requirements.

Maximum gross axle weight

The gross axle weight must not exceed the Gross Axle Weight Rating (GAWR).

GAWR (Y62 Patrol example only):

Rear
2,030 kg (4,475 lb)‡

The trailer must be loaded so that heavy goods are placed over the axle.

Tyre pressure

When towing a trailer, ensure that the tow vehicle’s tyre pressures are inflated to the recommended cold tyre specification. You will find these figures in the vehicle owner’s manual and on the tyre placard located in the vehicle. Trailer tyre condition, size, load rating, and tyre pressure must be in accordance with the trailer and tyre manufacturer’s specifications.

Do not tow a trailer when the vehicle is installed with a temporary spare tyre or a compact spare tyre.

Safety chains

Always use a suitable chain between the vehicle and trailer. The chain should be crossed and should be attached to the hitch, not to the vehicle bumper or axle. Be sure to leave enough slack in the chain to permit turning corners.

Trailer brakes

Ensure that trailer brakes are installed as required by local regulations. Also check that all other trailer equipment conforms to local regulations. Always block the wheels on both the vehicle and trailer when parking. Apply the hand brake on the trailer if equipped. Parking on a steep slope is not recommended. If parking on a steep slope is unavoidable, place the shift lever in the “P” (Park) position (for automatic transmission model), or in an appropriate position (for manual transmission model), and turn the front wheels towards the curb.

Vehicle modifications

Any accessories and modifications, genuine or aftermarket, fitted to the vehicle must always be considered when measuring vehicle loads. The extra weight added to the vehicle will consume an equivalent amount of the vehicle’s payload, leaving less payload available for passengers or cargo.

Towball download tables

Historically Nissan has provided Towball Download Tables for some models to be used as a guide for vehicle loading. These tables provided a recommendation for reduction in GVM loading as a guide to ensure GVM, GCM and GAWRs are not exceeded.

These Towball Download Tables are being gradually removed due to misinterpretation. This means it is ultimately up to you, the owner, to measure your vehicle and trailer weight distribution at a weighbridge to ensure GVM, GCM, TBD and axle ratings are not exceeded.

Towing safety

Towing can significantly alter the handling and performance characteristics of your vehicle. Moreover, it puts increased strain on the engine and drivetrain. Therefore, it is always a good idea to approach towing from the standpoint of safety — whether you are purchasing equipment or actually pulling the trailer. Buy or lease only quality equipment. You should follow a more frequent maintenance schedule and check fluid levels, proper tyre pressures, tyre condition, etc., more often when on the road to protect your vehicle.

Loading your trailer

As mentioned earlier, keep the towball download around 10% of the total trailer weight.

Do not carry flammable materials, such as petrol, in your trailer. In the event of an explosion a fire could occur, causing personal injury or death.

Before starting out

Before starting out on a trip, make one last inspection of the tow vehicle and the trailer. Are the tyre pressures correct? Are the safety chains/cables securely in place? Has the cargo been tied down securely? Do all the lights work? Is the coupler properly attached over the hitch ball and secured using a locking pin? Is the breakaway switch hooked up and functioning properly? Are your vehicle’s and electric trailer brakes working properly?

Make a checklist of key items to inspect. Before towing, always check the tow vehicle’s engine oil, transmission oil, and coolant before starting out. Finding a potential problem while in your driveway is better than discovering it far from home.

Tow mode (if equipped)

Tow mode is recommended when towing a heavy trailer or hauling a heavy load, in stop-and-go traffic, rolling terrain, or a busy parking lot. Driving the vehicle in tow mode may affect fuel economy and transmission/engine driving characteristics. See your vehicle owner’s manual for additional information about tow mode.
