WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.

X Remove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the

General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically to avoid exceeding the set speed or to
maintain the designated distance from the vehi- cle in front.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden. By doing so, you will make
use of the braking effect of the engine. This
relieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
If Distance Pilot DISTRONIC detects that there is a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately
to increase the distance to the vehicle driving in
front, or take evasive action, provided it is safe
to do so.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational. Driving systems

Tips for driving with Distance Pilot
DISTRONIC General notes
The following contains descriptions of certain
road and traffic conditions in which you must be particularly attentive. In such situations, brake if
necessary. Distance Pilot DISTRONIC will then
be deactivated.
Cornering, entering and exiting a bend The ability of Distance Pilot DISTRONIC to
detect vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles which are not driving in the mid-
dle of their lane Distance Pilot DISTRONIC may not detect vehi-
cles which are not driving in the middle of their
lane. The distance to the vehicle in front will be
too short. Driving syste
ms
167Driving an d parking Z

In a speed range from 0 - 60 km/h, Stop&Go
Pilot focuses on the vehicle in front, taking into
account lane markings, e.g. when following vehi-
cles in a traffic jam.
At speeds of more than 60 km/h, the Steering
Pilot focuses on detected lane markings (left
and right), only focusing on the vehicle in front if detected lane markings are not present at
speeds of up to 130 km/h.
If these conditions are not present, Steering
Pilot and Stop&Go Pilot cannot provide assis-
tance.
Distance Pilot DISTRONIC must be active in
order for the function to be available.
Important safety notes If you fail to adapt your driving style, Distance
Pilot DISTRONIC with Steering Pilot and
Stop&Go Pilot can neither reduce the risk of an
accident nor override the laws of physics. It can-
not take into account road, weather or traffic
conditions. Distance Pilot DISTRONIC with
Steering Pilot and Stop&Go Pilot is only an aid.
You are responsible for the distance to the vehi- cle in front, for vehicle speed, for braking in good
time and for staying in lane.
Distance Pilot DISTRONIC with Steering Pilot
and Stop&Go Pilot does not detect road and
traffic conditions and does not detect all road
users. If you are following a vehicle which is
driving towards the edge of the carriageway,
your vehicle could come into contact with the
kerb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the opposite direction.
Distance Pilot DISTRONIC with Steering Pilot
and Stop&Go Pilot cannot continuously keep
your vehicle in the lane. In some cases, the
steering intervention is not sufficient to bring
the vehicle back to the lane. In such cases, youmust steer the vehicle yourself to ensure that it
does not leave the lane. The support offered by the system may be
impaired if:
R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,fog or spray
R there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no lane markings, or several unclear
lane markings are present, e.g. around con-
struction sites
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the road
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lanes
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
i After you have finished changing lanes,
Steering Pilot and Stop&Go Pilot are auto-
matically active again.
Steering Pilot and Stop&Go Pilot cannot provide
assistance:
R on very sharp corners
R a loss of tyre pressure or a defective tyre has
been detected and displayed
Pay attention also to the important safety notes
on Distance Pilot DISTRONIC (Y page 162).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with a visual warning. A steering wheel symbol
appears in the multifunction display. If you have Driving systems

still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Pilot and

General notes The limiter brakes automatically so that you do
not exceed the set speed. On long and steep
downhill gradients, especially if the vehicle is
laden, you must select a lower gear in good time.
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.
You can set a variable or permanent limit speed:
R variable for maximum permissible speeds,
e.g. in built-up areas
R permanent for long-term speed restrictions,
e.g. when driving with winter tyres fitted
(Y page 172)
i The speed indicated in the speedometer
may differ slightly from the speed stored.
Important safety notes If you fail to adapt your driving style, the limiter
can neither reduce the risk of an accident nor
override the laws of physics. The limiter cannot take into account road, weather or traffic con-
ditions. The limiter is only an aid. You are
