Introduction i
OnAMG vehicles andvehicles with
steering wheel gearshift paddles,y ou
can restrict or derestric tthe shift range
using the steerin gwheel gearshift paddles.
When the automatic transmission is in posi-
tion D,itisp ossible to restrict or derestrict
the shift range (Y page 153).
The shift range selected is shown in the mul-
tifunction display .The automatic transmis-
sion shifts only as far as the selected gear. Shift range: =
To use the engine's braking effect
5
To use the braking effect of the
engine on downhill gradients and
for driving:
R
on steep mountain roads
R in mountainous terrain
R in arduousc onditions 4
To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretches
Restricting the shift range
X
Pull the left-hand steering wheel gearshift
paddle.
The automatic transmission shifts down
one gear and restrictst he shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protectsa gainst engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up,
even if the shift range is restricted. This
prevents the engine from overrevving.

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steerin gand the brake boostin
geffect. You will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. ECO display
ECO display (example)
The ECO display gives you information on how
economical your driving style is. The ECO dis-
play assists you in achieving the optimum
driving style in term
sofconsumption ,taking
the actual and selected conditions into con-
sideration. Your driving style can significantly
influenc ethe vehicle's consumption.
The ECO display consists of three bars:
R Acceleration
R Constant
R Coasting
The percen tvalue is th eaverage value of the
three bars .The three bars and the average
value commence with avalue of 50%. Ahigher
percentage indicates amoree conomical driv-
ing style.
The ECO display provides no information on
the actual fue lconsumption. Afixed percent-
age value of the ECO display does not corre-
spon dtoaf ixed consumption figure in
l/100km.
Apar tfromd rivin gstyle, consumption is
dependent on many factors such as:
R load
R tyre pressure
R cold start
R selected route
R number of consumer sthat are switched on Driving tips

These variable are not included in the ECO

Your driving style is evaluated on the basis of
the following three categories:

tion processes)

On long journeys at constan tspeed, such
as on the motorway, only the "Constant"
category bar changes.
i The ECO display sums up the driving
behaviour from the start to the end of the
journey. As aresult, the bars change
dynamically at the start of the journey. Dur-
ing long journeys ther eare fewer changes.

! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This may lead to fuel
collectin ginthe engin eoil and cause
engin efailure. Therefore, if you frequently
drive short distances, you should tak ea20
minut etriponam otorway or rural road at
least every 500km. Brakes
Important safet ynotes G
WARNING
If you shift down on aslippery road surfac ein
an attempt to increase the engine's braking
effect ,the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engin ebrak-
ing on aslippery road surface.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range

Driving tipsDriving and parking

The wear of individual componentsoft
he
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage lifetime that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information about this from your Mercedes-
Benz Servic eCentre.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometres of driving. Compen-
sate for this by applying greater force to the
brake pedal. Do not forget this, and adapt
your driving and braking accordingly during
this run-in period.
Excessively heavy braking results in corre-
spondingly high brake wear. Observe the
brake system warning lamp in the instrument
cluster and notea ny brake status messages
in the multifunction display .For high-per-
formanc edriving in particular, it is important
to maintain and have the brake system
checked regularly. Driving on wet roads
Aquaplaning If water has accumulated to
acertain depth
on the road surface, there is adanger of aqua-
planing occurring, even if:
R you are driving at low speeds.
R the tyres have adequate tread depth.
For this reason, do not drive in tyre ruts and
brake carefully.
Driving on flooded roads !
Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam- age the engine, the electronics or the trans-
mission.
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permissible still water depth
is 25 cm.
R you should drive no faster than at walking
pace. Winter driving
Important safety notes G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect ,the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
aw indow on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 330).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
