Parking
Important safety notes
G WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is ar isk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
G WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example: R
release the parking brake. R
shift the automatic transmission out of the
parking position P .R
start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is ar isk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
! Always secure the vehicle correctly against
rolling away .O therwise, the vehicle or its driv-
etrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally: R
the electric parking brake must be applied. R
the transmission must be in position ] and
the transmission position display must show
] in the multifunction display. R
the SmartKey must be removed from the igni-
tion lock. R
on uphill or downhill gradients, the front
wheels must be turned towards the curb. Switching off the engine

G WARNING
The automatic transmission switches to neu-
tral position N when you switch off the engine.
The vehicle may roll away .T here is ar isk of an
accident.
After switching off the engine, always switch
to parking position P .P revent the parked vehi-
cle from rolling away by applying the parking
brake.

ECO display The ECO display show sy ou how economical
your driving style is. The ECO display assists you
in achievin gt he mos te conomical driving style

tions .Y our driving style can significantly influ-
enc et he vehicle's consumption.

Coasting

In addition to driving style, the actual consump-
tion is affected by other factors, such as: R
Load R
Tire pressure R
Cold start R
Choice of route R
Active electrical consumers
These factors are not include dint he ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving ah igher valu eint he categories
"Acceleration" and "Constant": R
observe the gearshift recommendations. R
drive the vehicle in drive program C or E
(vehicles with aD YNAMIC SELECT button).
On long journeys at ac onstant speed ,e .g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer area satt he start of aj ourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform am anua lr est

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 and steep gradients, you must
reduce the load on the brakes by shifting to a
lowe rg ear in good time. This allows you to
take advantage of engine braking. For this you
must first activate manua lg earshifting. This helps you to avoid overheating the brakes and
wearing them out excessively.
When you take advantage of engine braking, it
is possible that ad rive wheel wil ln ot rotate for
some time, e.g. on as lippery road surface.
This could cause damage to the drive train.
This type of damage is not covered by the
Mercedes-Benz warranty.
Briefly depressing the accelerator peda lo n
downhill gradients whil et he manua ld rive pro-
gram M is temporaril ya ctivated: the automatic
transmission may switch to the last active auto-
matic drive program E or S .T he automatic trans-
missio nm ay shift to ah ighe rg ear. This can
reduce the engine's braking effect.
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 .D rive
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 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.146
Driving tips

Limited braking performance on salt-
treated roads If you driv eons alted roads ,al ayer of salt resi-
due may for mont he brak ed isc sa nd brake
pads. This can result in as ignificantly longer
braking distance. R
In orde rtop revent any salt build-up, apply the
brakes occasionally while paying attention to
th et ra ffic conditions.R
Carefully depress th eb rak ep edal and the

4MATIC
! Never tow the vehicle with one axle raised.
This may damage the differential. Damage of
this sort is not covered by the Mercedes-Benz
Limited Warranty. All wheels must remain
either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
4MATIC, together with ESP ®
,i mproves the trac-
tion of your vehicle whenever ad rive wheel
spins due to insufficient grip. If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of accident nor override
the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions.
4MATIC 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
your lane.
If ad rive wheel spins due to insufficient grip: R
Only depress the accelerator pedal as far as
necessary when pulling away. R
Accelerate less when driving.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.
DYNAMIC BODY CONTROL
General notes DYNAMI CB ODY CONTROL offers improved
driving comfort and continuously controls the
calibration of the dampers. The
damping characteristics adapt to the current
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 drive program selected
The drive program can be set using the
DYNAMI CS ELECT button ( Y
page 128).
Selecting Comfort mode In the Comfort drive program, the driving char-
acteristic sofy our vehicle are more comforta-
ble. Therefore, select this drive program if you
prefer am ore comfortable driving style. Also
select the Comfort drive program when driving
fast on straight roads, e.g. on straight stretches
of highway. X
