TOWING A TRAILER,
CARAVAN, BOAT etc.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage of
your vehicle. The tow bar must be
fitted by a PEUGEOT dealer. Y our vehicle is primarily designed for
transporting people and luggage but
it may also be used for towing a trailer. Driving with a trailer subjects the towing vehicle to more significantstress and its driver must be particu-larly careful. Air density decreases with altitude, thus reducing engine performance.Above 1000 metres, the maximumtowing load must be reduced by 10%and so on for every 1000 metres ofaltitude. Driving advice Distribution of loads:Distribute the load in the trailer so that the heaviest items are as closeas possible to the axle and the noseweight approaches the maximumpermitted without exceeding it. Cooling: T
owing a trailer on a slope increases
the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependenton the engine speed.
On the contrary, use a high gear to lower the engine speed, and reduceyour speed. The maximum towing load on a long slope depends on the gradient andthe outside temperature. In all cases, pay attention to the coolant temperature. If the warning light comes on, stop
the vehicle and switch off the engineas soon as possible. T
yres:
Check the tyre pressures of the tow-
ing vehicle and of the trailer, observ-ing the recommended pressures. Braking: T owing increases the braking dis-
tance. Lights: Check the electrical signalling on the
trailer. Side wind: T ake into acount the increased sen-
sitivity to side wind.
