A stored speed appears under the h display
and is indicated in the speedometer.
System limits
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Increase recuperation in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so, you
will make use of the electric motor's braking
effect to charge the high-voltage battery. This
relieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
Do not use cruise control in the following situa-
tions:
in traffic situations which require frequent
R
changes of speed, e.g. in heavy traffic, on
winding roads
on slippery roads. Accelerating can cause the
R
drive wheels to lose traction and the vehicle
could then skid.
when visibility is poor

& WARNING Risk of accident due to stored
speed
If you call up the stored speed and this is
lower than your current speed, the vehicle
decelerates.
Take into account the traffic situation

before calling up the stored speed.
