In addition to driving style, the actual consump-

These factors are not include dint he ECO dis-

An economical driving style specially requires
driving at moderate engine speeds.

In urba nt raffic and stop-start traffic, drive pro-

On long journeys at ac onstant speed ,e .g. on the

Braking
Important safety notes
G WARNING
If you shift down on as lippery road surface in
an attempt to increase the engine's braking
effect, the drive wheel sc ould lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on as lippery road surface.
Downhill gradients
! On long, steep gradients, you must reduce
the load on the brakes. To use engine braking,
shift to al owe rg ear in good time. This helps you to avoid overheating the brakes and wear-
ing them out excessively.
When making use of the engine braking
effect, it is possible that ad rive wheel may not
turn for some time, e.g. in the case of sud-
denly changing or slippery road surface con-
ditions. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Change into al owe rg ear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
This also applies if you have activated cruise
control or Distance Pilo tD ISTRONIC.
Heavy and light loads
G WARNING
If you rest you rf oot on the brake peda lw hile
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail .T here is a
risk of an accident.
Never use the brake peda lasaf ootrest. Never
depres st he brake peda la nd the accelerator
peda latt he same time.
! Depressing the brake peda lc onstantly
results in excessive and premature wea rt o
the brake pads.
If the brakes have been subjected to ah eavy
load ,don ot stop the vehicle immediately ,b ut
drive on for as hort while. This allows the airflow
to cool the brakes more quickly.
Wet roads If you have driven for al ong time in heavy rain
withou tb raking, there may be ad elayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You then have to depres st he brake peda lm ore
firmly .M aintai nag reater distance from the
vehicle in front.
After driving on aw et road or having the vehicle
washed, brake firmly whil ep aying attention to
the traffic conditions. This wil lw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.136

road speed above 20 mph (30 km/h).
Important safety notes If you fail to adap ty our driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front ,f or vehicle speed, for braking in
good time and for staying in lane.
Do not use cruise control: R
in road and traffic conditions which do not
allow you to maintain ac onstant speed e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could 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 ac hange of drivers, advise the new

The damping characteristic sa dapt to the cur-
rent operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the selected drive program ( Y

Selecting the Comfort or Economy drive
programs In the Comfort and Economy drive programs,
the driving characteristic sofy our vehicle are
more comfortable. Select one of these drive
programs if you favor am ore comfortable driv-

driving fast on straight roads, e.g. on straight
stretches of highway.
In urban traffic and stop-start traffic, drive pro-
gram C is recommended. X
Press DYNAMIC SELECT button C repeat-
edly until the Comfort or Economy drive pro-
gram is selected.
Selecting Sport mode The firmer setting of the suspension tunin gi n

Parking Guidance
Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. As uitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You can also still use Active Parking
Assist PARKTRONIC ( Y

Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-

for safe maneuvering, parking and exiting a
parking space. Make sure that there are no per-
sons, animals or object sint he maneuvering
area when you are maneuvering or parking.
G WARNING
If object sa re located above or below the
detection range, Active Parking Assist may
steer too early. This could cause ac ollision. There is ar isk of an accident.
Do not use Active Parking Assist in these
types of situation.
! If they cannot be avoided, drive over obsta-

angle. Otherwise, you may damage the
wheels or tires.
If Active Parking Assist PARKTRONIC is deacti-
vated, Parking Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
