Weights
Towing weights
Weights (in kg)
the weights indicated for a basic vehicle without options: they vary depending on the your vehicle’s equipment. consult
your approved dealer.
maximum permissible all-up weight (mmac)
gross t rain Weight (mtR) Weights are indicated on the vehicle identification plate (refer to
the information on “Vehicle identification plates” in Section 6)
Braked t railer Weight* found by calculating:mtR - mmac
Unbraked t railer Weight* 650
permissible nose weight* 75
permissible load on the roof with the carrying device 80 kg (including the carrying device)
* t owing weight (towing a caravan, boat, etc.)
Towing is prohibited when the MTR - MMAC calculation is equal to zero, or when the MTR is equal to zero (or is not listed) on the
identification plate.
– It is important to comply with the towing weights, governed by local legislation in each country and, in particular, laid down in
the Road Traffic Regulations. Contact your approved dealer about any towing equipment.
– When towing, under no circumstances may the total train weight (vehicle + trailer) be exceeded . However the following is
permitted:
– rear axle MMTA exceeded by no more than 15%,
– maximum MMAC exceeded by no more than 10% or 100 kg (whichever is reached first).
In either case, the maximum speed of the vehicle and trailer must not exceed 60 mph (100 kph) and the tyre pressures must
be increased by 0.2 bar (3 PSI).
– The engine output and climbing capability are reduced with altitude. We recommend that the maximum load be reduced by 10%
at an altitude of 1,000 metres and by an additional 10% for each 1,000 metres thereafter .
Weight transfer
The towing load must not exceed 1,500 kg.
If the Maximum Authorised Mass of the vehicle has not been reached, up to 200 kg can be transferred to the braked trailer, within
the limits of the Gross Train Weight.
