TOWING A TRAILER,
CARAVAN, BOAT etc.
Only use original PEUGEOT tow bars that have been tested andapproved from the design stage ofyour vehicle. The tow bar must be fitted by a
PEUGEOT dealer.
Your 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 1 000 metres, the maximum
towing load must be reduced by 10 %
and so on for every 1 000 metres ofaltitude.Driving advice Distribution of loads:
Distribute the
load in the trailer so that the heaviest items are as close as possible to theaxle and the nose weight approachesthe maximum permitted withoutexceeding it. Cooling: Towing 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. Tyres:
Check the tyre pressures of
the towing vehicle and of the trailer,observing the recommended pres-sures. Braking: Towing increases the brak-
ing distance.Lights: Check the electrical signalling
on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.
