154 Driving and operationDriving hintsThe first 600 miles (1000 km)Drive your vehicle at various speeds.Do not use full throttle. Never allow theengine to labour at low revs.Make good use of all gears. Depress theaccelerator pedal a maximum of about 3 /4of the available pedal travel in all gears.Do not drive faster than three quarters ofmaximum speed.Do not brake unnecessarily hard for thefirst 125 miles (200 km).Never coast with engine not runningMany units will not function in this situation(e.g. brake servo unit, electro-hydraulicpower steering). Driving in this manner isa danger to yourself and others.Brake servo unitWhen the engine is not running, the brakeservo unit is no longer effective once thefootbrake has been depressed once ortwice. Braking effect is not reduced, butsignificantly greater force is required forbraking.Electro-hydraulic power-assisted steeringIf the power-assisted steering fails whenbeing towed with the engine switched off,the vehicle can still be steered, butconsiderably more force is required.Driving in mountainous terrain or with acaravan/trailerThe 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.Driving with a roof loadDo not exceed the permissible roof load –see pages 185, 275. For reasons of safety,distribute the load evenly and strap it downfirmly using retaining straps so that itcannot slip. Check the tyre pressure whenthe vehicle is loaded. Do not travel inexcess of 75 mph (120 km/h). Frequentlycheck the attachment and retighten. Notecountry-specific regulations.Switching off the engineWhen you switch off, fans in the enginecompartment may continue running for atime to cool the engine.If the engine temperature is very high, e.g.after driving in mountainous terrain: allowthe engine to idle for approximately twominutes in order to prevent heataccumulation.Vehicles with turbocharged engineAfter running at high engine speeds or highengine loads, operate the engine briefly ata low load or run in neutral for approx.30 seconds before switching off in order toprotect the turbocharger.Save energy – more milesPlease observe the running-in hints on theprevious page and the tips for savingenergy on the following pages.Good, technically correct and economicaldriving ensures maximum durability andperformance for your vehicle.Ofrecido por www.electromanuales.com
