Cruise control may be unable tomaintain the

speed is resumed when the gradient evens out.
On long and steep downhill gradients, you should
ch ange down toa lo werge ar in good time. Take
particular no teofthis when driving a laden vehi‐

Do not use cruise control in thefo llowing situa‐

R In traf fic situations whe refrequent speed

on winding roads.
R On slippe ryroads. Accele rating can cause the
