Instrument cluster
Tachometer
The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature indicator is on
the bottom left-hand side of the instru-
ment cluster.
The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next to the sensor,
not by comparison to external displays
(e.g. bank signs, etc.).When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
Fuel gauge
The fuel gauge is on the left-hand side of
the instrument cluster (
page 28). Once
the fuel level has fallen below the reserve
mark, the yellow segment indicator for the
fuel reserve comes on (page 550).
!
Excessive coolant temperature triggers a
warning in the multifunction display
(
page 588).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C), i.e. in
the red zone of the coolant temperature gauge.
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz Lim-
ited Warranty.
i
During severe operating conditions,
e.g. stop-and-go traffic, the coolant temperature
may rise close to 248°F (120°C), i.e. close to
the red zone of the temperature gauge.
!
Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warran-
ty.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

380 Controls in detailDriving systemsThe driving systems of your vehicle are de-
scribed on the following pages:

Cruise control and DISTRONIC Plus*,
with which the vehicle can maintain a
preset speed.


Distance warning function* (only avail-
able with DISTRONIC Plus*), which
warns of a stationary obstacle or slow-
er moving vehicle that you are closing
on to quickly.


Airmatic (S 550 only) and ABC* adjust
the vehicle suspension characteristics
automatically and control the vehicle
level.


Parktronic* and Park Assist*, which
serve as a parking assistant.


Dynamic Rear View Monitor* is an
electronic and visual parking aid.


Night View Assist* illuminates the road
with infrared light in addition to the nor-
mal headlamps.For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, and ESP
® driv-
ing systems, see “Driving safety systems”
(
page 69).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
The use of cruise control is recommended
for driving at a constant speed for extend-
ed periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Warning!
G
Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal depresses when cruise control engag-
es the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
– your foot could become caught.
Keep in mind that cruise control is a conve-
nience system designed to assist the driver
during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.

Driving systems
DISTRONIC Plus*
When activated, the DISTRONIC Plus adap-
tive cruise control system increases driv-
ing convenience afforded by the cruise
control during travel on expressways and
other major roads.

If the DISTRONIC Plus distance sensor
detects a slower moving vehicle direct-
ly ahead, your vehicle speed will be re-
duced so that you follow that vehicle at
a preset distance.


If there is no vehicle directly ahead of
you, DISTRONIC Plus will function in
the same way as cruise control
(page 380).
DISTRONIC Plus functions within a speed
range of 0 to 124 mph (0 to 200 km/h).
Warning!
G
DISTRONIC Plus is a convenience system.
Its speed adjustment reduction capability is
intended to make cruise control more effec-
tive and usable when traffic speeds vary. It
is not however, intended to, nor does it, re-
place the need for extreme care. The re-
sponsibility for the vehicle speed and the
distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always rests with
the driver.
DISTRONIC Plus cannot take street and traf-
fic conditions into account.
Complex driving situations are not always
fully recognized by DISTRONIC Plus. This
could result in wrong or missing distance
warnings.
Warning!
G
The DISTRONIC Plus adaptive cruise control
is no substitute for active driving involve-
ment. It does not react to pedestrians or sta-
tionary objects, nor does it recognize or
predict the curvature and lane layout or the
movement of vehicles ahead.
DISTRONIC Plus can only apply a maximum
of 40% of the vehicle’s braking power.
DISTRONIC Plus may not detect narrow ve-
hicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle.
High-frequency sources such as toll sta-
tions, speed measuring systems etc. can
cause the DISTRONIC Plus system to tem-
porarily cease functioning properly.

386 Controls in detailDriving systemsWarning!
G
DISTRONIC Plus requires familiarity with its
operational characteristics. We strongly rec-
ommend that you review the following infor-
mation carefully before operating the
system.Warning!
G
DISTRONIC Plus cannot take street and traf-
fic conditions into account. Only use
DISTRONIC Plus if the road, weather and
traffic conditions make it advisable to travel
at a steady speed.Warning!
G
Use of DISTRONIC Plus can be dangerous
on slippery roads. Rapid changes in tire trac-
tion can result in wheel spin and loss of con-
trol.
DISTRONIC Plus does not act upon adverse
sight distance conditions. Do not use
DISTRONIC Plus during conditions of fog
and heavy rain, snow or sleet.Warning!
G
DISTRONIC Plus cannot take weather condi-
tions into account. Switch off
DISTRONIC Plus or do not turn it on if:

roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid.


the sensor is dirty or visibility is
diminished due to snow, rain or fog. The
distance control could be impaired.
Always pay attention to traffic conditions
even while DISTRONIC Plus is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.
Warning!
G
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not DISTRONIC Plus is activated.
Use of DISTRONIC Plus can be dangerous
on winding roads as conditions do not allow
safe driving at a steady speed.
DISTRONIC Plus may not react to stationary
objects in the roadway (e.g. a stopped vehi-
cle in a traffic jam or a disabled vehicle).
DISTRONIC Plus will also not respond to on-
coming vehicles.

switch on DISTRONIC Plus if the vehicle ahead of
you has been detected and is shown on the mul-
tifunction display. If you no longer see the vehi-
cle in front of you on the multifunction display
and if it is no longer detected because it has
changed lanes, for example, DISTRONIC Plus
switches off and you will hear a signal.

If you do not completely lift your foot off the
accelerator pedal, the message“DISTRONIC
PLUS passive” appears on the multifunction dis-
play. The distance to a slower-driving vehicle will
not be set. You will drive at the speed you dictate
by pressing the accelerator pedal.
i
It is helpful to switch on the DISTRONIC Plus
display in the instrument cluster since you can
only switch on DISTRONIC Plus under a speed of
20 mph (30 km/h) when a vehicle has been de-
tected in front of you.
i
You can adjust the set speed using the
DISTRONIC Plus lever and the target distance
using the distance setting switch on the
DISTRONIC Plus lever (
page 396).
i
The distance warning function will still issue
warnings even when DISTRONIC Plus is switched
off if you have activated it on using the instru-
ment cluster control system (

Driving
If no vehicle is driving ahead of you, DIS-
TRONIC Plus functions like cruise control
(
page 380).
When DISTRONIC Plus detects that the ve-
hicle in front of you is driving more slowly,
it brakes the vehicle in order to keep the
distance specified by you.
When DISTRONIC Plus detects that the ve-
hicle in front of you is driving faster, the ve-
hicle accelerates up to the set speed.Stopping
