light MERCEDES-BENZ C-CLASS CABRIOLET 2016 Manual Online

You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. Do not use
cruise control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position
N.
X Try to bring the vehicle under control by using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges. The vehicle could
skid if you fail to adapt your driving style. Always adapt your driving style and drive at a speed to
suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

Further information on driving safety systems
(Y page 66). Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Shift to a lower gear in
good time on long and steep downhill gradients.
Take particular note of this when driving a laden vehicle and when towing a trailer. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steadyspeed for a prolonged period. You can store anyroad speed above 30 km/h. If you have set a
permanent limit speed, you cannot set the
speed any higher than the fixed limit speed
(Y page 171).
Important safety notes Cruise control can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. Cruise control can- not take into account road, weather or traffic
conditions. Cruise control is only an aid. You are
responsible for maintaining a safe distance from the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Do not use cruise control:
R in road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow.
If there is a change of drivers, advise the new
driver of the speed stored.

General notes SPEEDTRONIC is used to set a speed limit for
your vehicle. If the vehicle speed exceeds the
set speed limit, SPEEDTRONIC brakes automat-
ically. Shift to a lower gear in good time on long and steep downhill gradients. Take particular
note of this when driving a laden vehicle and
when towing a trailer. 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.
Important safety notes SPEEDTRONIC can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. SPEEDTRONIC
cannot take into account road, weather or traffic
conditions. SPEEDTRONIC is only an aid. You
are responsible for maintaining a safe distance
from the vehicle in front, for vehicle speed, for
braking in good time and for staying in lane.
If there is a change of drivers, advise the new

You can set a variable or permanent limit speed:
R variable for speed limits, e.g. in built-up areas
R permanent for long-term speed restrictions,

Switching SPEEDTRONIC to passive
If you depress the accelerator pedal beyond the
pressure point (kickdown), SPEEDTRONIC is
switched to passive mode. The multifunction
display shows the SPEEDTRONIC suspended
SPEEDTRONIC suspended
message and you are able to exceed the stored speed. If SPEEDTRONIC is switched to passive
mode, SPEEDTRONIC will not brake automati-
cally until it is activated again.
SPEEDTRONIC is activated again if you:
R drive slower than the stored speed without
kickdown
R set a new speed or
R call up the last speed stored again
The SPEEDTRONIC suspended SPEEDTRONIC suspended message on the
multifunction display then disappears.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable SPEED-
TRONIC by braking.
There are several ways to deactivate variable
SPEEDTRONIC:
X Briefly press the cruise control lever forwards
B.
or X Briefly press the cruise control lever in the
direction of arrow A.
Cruise control or DISTRONIC PLUS is selec-
ted. LIM indicator lamp ;in the cruise con-
trol lever goes out.
Vehicles with manual transmission: variable
SPEEDTRONIC switches off automatically if you shift to too high a gear and as a result the engine
speed drops sharply. A warning tone sounds,
the message on the multifunction display dis-
appears and the segments on the speedometer
go out.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC You can use the on-board computer to limit the
speed permanently to a value between
160 km/h (e.g. when driving on winter tyres)
and 240 km/h(Y page 237).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active even
if variable SPEEDTRONIC is deactivated. You cannot exceed the stored limit speed, even
if you depress the accelerator pedal beyond the pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the vehicle detected in front. Vehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into 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 overheat-
ing and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of collision with the vehicle in front, you will be
warned visually and audibly. Without your inter-
vention, DISTRONIC PLUS cannot prevent a col-
lision. 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 in front,
or take evasive action, provided it is safe to do
so.
DISTRONIC PLUS operates in the speed range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Driving systems

Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of DISTRONIC PLUS to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or late.
R Driving on a different line: DISTRONIC PLUS
may not detect vehicles that are not driving in
the middle of their lane. The distance to the
vehicle in front will be too short.
R Other vehicles changing lane: DISTRONIC
PLUS has not detected the vehicle cutting in
yet. The distance to this vehicle will be too
short.
R Narrow vehicles: DISTRONIC PLUS has not
yet detected the vehicle in front on the edge
of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R Obstacles and stationary vehicles:
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals an
obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
R Crossing vehicles: DISTRONIC PLUS may mis-
takenly detect vehicles that are crossing your
lane. Activating DISTRONIC PLUS at traffic
lights with crossing traffic, for example, could
cause your vehicle to pull away unintention-
ally.
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated. Driving syste

DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot aids you in keeping the vehicle in
the centre of the driving lane by means of mod-
erate steering interventions in a speed range
from 0–200 km/h.
It monitors the area in front of your vehicle by
means of multifunction camera :, at the top of
the windscreen.
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 you are fol-
lowing vehicles in a traffic jam.
At speeds of more than 60 km/h, Steering
Assist focuses on detected lane markings (left
and right), only focusing on the vehicle in front if detected lane markings are not present.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide assis-
tance.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notesDISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. It cannot take into account road, weather or traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay- ing in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If
you are following a vehicle that is driving towards the edge of the carriageway, your vehi-
cle 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 out into the lane are not detected.
An inappropriate steering intervention, e.g. after
you have intentionally driven over a lane mark-
ing, can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not
leave the lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or spray
R 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 no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
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 so small
that the lane markings cannot be detected
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 roadway
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
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
After you have finished changing lanes, Steering
Assist and Stop&Go Pilot are automatically
active again. 178
Driving syste
msDriving and parking

Steering Assist and Stop&Go Pilot cannot pro-
vide assistance in the following situations:
R on very sharp corners
R when a loss of tyre pressure or a defective
tyre has been detected and displayed
Also observe the important safety notes for
DISTRONIC PLUS (Y page 171).
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 on the multifunction display. If you have 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 Assist
