Keep in mind that the climbing ability of the vehicle depends on terrain conditions. Be easy on the accelerator and watch for continuous wheel traction when driving in steep terrain. RComply with the warnings (Y page 248) and rules for off-road driving (Y page 248). RDriving on embankments, slopes and other steep inclines should only be done straight up or downhill, i.e. in the line of gravity.
