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 basically designed for transporting people and luggage butit 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.The maximum towing load must
be reduced by 10 % for every
1 000 metres of altitude. 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 approach-es the maximum permitted withoutexceeding it. Cooling:
Towing a trailer on a slope
increases the temperature of thecoolant. 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 speed on a long slope depends on the gradientand the outside temperature. For vehicles fitted with a direct injec- tion petrol engine, after towing or dri-ving at high speed for a long periodof time, the fan may operate forapproximately 6 minutes. 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 the trailer,observing the recommended pres-sures. Brakes: Towing increases the braking
distance. Lights: Check the electrical sig-
nalling on the trailer.Side wind: Take into acount the
increased sensitivity to side wind.
