228 Roof Racks, Caravan and Trailer TowingIf necessary, the gears can also be selectedmanually.The cooling fan is electrically operated. Itscooling power is therefore independent ofthe engine speed.Since a considerable amount of heat isgenerated at high engine speeds and lessat slower speeds, do not shift down whenclimbing hills whilst the vehicle is still copingwith the gradient in the higher gear.Diesel engine: On rising gradients of 10% ormore, do not drive faster than 20 mph(30 km/h) in 1st gear or 30 mph (50 km/h)in 2nd gear; with automatictransmission 3, do not exceed 25 mph(40 km/h) in position 1.Picture no: 17730j.tifStarting on inclinesFor vehicles with manual transmission, themost favourable engine speed whenstarting off on an incline is between 2500and 3000 rpm for petrol engines andbetween 2000 and 2200 rpm for dieselengines. Hold engine speed constant,engage clutch gradually (let slip), releasehand brake and open throttle. If possible,the engine speed should not drop duringthis procedure.For vehicles with automatic transmission 3or Easytronic 3 in automatic mode it issufficient to apply full throttle.Before starting off under extremeconditions (high combination weight,mountainous terrain with steep inclines),switch off all unnecessary electrical loads(e.g. heated rear window, air conditioningsystem 3, heated seats 3).Ofrecido por www.electromanuales.com
