Doing so could reduce driving comfort. Trailer operation When towing a trailer, do not allow engine speed to drop too low on inclines. Select a lower range ("3", "2" or "1") in time, depending on the degree of the incline. This is also valid with cruise control activated. At extreme inclines switch to LOW RANGE mode, see page 209. Note: For detailed information see trailer towing on page 190. If the engine does not brake the vehicle sufficiently while driving on a downgrade, the speed you set on the cruise control may be exceeded. In this case the automatic transmission shifts down (max. to 3rd gear) to maintain the set cruise control speed by using the engine's braking power. As soon as the grade eases, the automatic transmission shifts up again dependent on the selector lever position. Nevertheless, in some cases you may have to step on the brake pedal to slow down. In this case the cruise control is switched off. Use the lever to resume the previously set speed.
