ble up to a maximum speed of 155 mph

yet activated.

A stored speed appears along with the h dis-
play.
%
The segments between the stored speed and
the end of the segment display light up 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.
Change to a lower gear 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 braking effect of the engine.
This relieves the load on the brake system and
prevents 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
