R Byflashing brake lamps
R By activating the hazard warning lights
If th eve hicle is braked sharply from speeds
abo ve50 km/h, the brake lamps flash rapidly.
This pr ovides traf fic tr ave lling behind you with an
eve n more noticeable warning.
If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once
th eve hicle is stationar y.When pulling away

also swit choff the hazard warning lights using

Fu
nction of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed. If
yo u accelerate to overtake ,fo rex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐

ing in lane.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the braking ef fect
of the engine. This relie vesth e load on the brake sy
stem and pr events the brakes from overheat‐

Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the

is operational at speeds of up toappr oximately
35 km/h. When all the conditions are fulfilled,
th ec symbol appears in the multifunction
display and the sy stem automatically sear ches
fo r and measu res parking spaces on bo thsides

The parking space and, if necessar y,the parking
direction can be selected as desired. Parking
Pilot calculates a suitable vehicle path and
assists you in parking and exiting the parking

Pa rking Pilot changes gear, accelerates, brakes
and steers theve hicle.
Pa rking Pilot is only an aid. It is not a substitute
fo ryo ur attention tothe sur roundings. The
