When towing (usually 1800kg) I always use Auto mode - it makes a huge difference well pulling away - when the nose weight of the trailer can make the front wheels less useful.
2 weeks ago I was towing a twin axle trailer full of stuff for the new house - I estimated around 1700kg worth + the car was pretty full. Anyway on the way up the hill we had to slow because of a cyclist - I dropped into first and stalled. The road was wet as it was still raining.
I tried a gentle-ish start in AUTO - the car stalled again - and the clutch let off a whiff.
I switched to permie 4*4 - tried the same gentle start - again the car stalled despite trying to dip and blip - and the clutch smelled some more.
Final attempt - dialed in 3500rpm - side stepped the clutch - kept the throttle down - and let the X-Trail 4 wheel spin itself away. It managed it. The rest of the journey up to the house I kept the car in 2nd gear - except for the 2nd hairpin (1st gear - the right hander see the map) - and by the time the trailer had been reversed onto the drive the coolant was around 75% on the dial and the clutch was smelling pretty strong.
The car has recoved since and still feels as it did beforehand. :mrgreen: :mrgreen:
The road if from Fly (440m) to Amden (900m) - about 1-in-10 all the way up.
