Driving tips
Maintain a greater distance to the vehicle in
R
front than when driving without a trailer.
Avoid braking abruptly. If possible, brake gen-
R
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
The values given for gradient-climbing capa-
R
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas-
ing altitude.
