Important safety notes
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle has been delivered or after repairs. Full sys-
tem effectiveness is not reached until the end
of this teach-in process.
Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres of driving. Compensate for the
reduced braking effect by applying greater
force to the brake pedal. The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with excellent performance for the remainder of
the engine's life.
R Drive at varying road speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When changing gears manually, change up
in good time, before the rev counter needle reaches
Ôof the way to the red area of the
rev counter.
R Do not shift down a gear manually in order
to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick- down).
R All vehicles (except Mercedes-AMG
vehicles): drive the vehicle mainly in drive
program Efor the first 1500 km.
Additional notes on running in Mercedes-
AMG vehicles:
R Do not drive at speeds above 140 km/ hfor
the first 1,500 km.
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Drive the vehicle mainly in drive program C
for the first 1,500 km.
After 1,500 km, you may gradually accelerate the vehicle to full road and engine speeds.
You should also observe these notes on run-
ning-in if the engine or parts of the drive train
on your vehicle have been replaced.
Always observe the maximum permissible
speed. Driving

WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another. 160

Shifting gears
If you pull on the left or right-hand steering
wheel gearshift paddle, the automatic trans-
mission switches to manual drive program M
for a limited amount of time. Depending on which gearshift paddle is pulled, the auto-
matic transmission immediately shifts into
the next gear up or down, if permitted.
X To shift up: pull the right-hand steering
wheel gearshift paddle (Y page 174).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed on the cur-
rently engaged gear is reached and you
continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage.
Mercedes-AMG vehicles: the automatic
transmission will not shift up to the next
gear when the engine speed is very low.
X To shift down: pull on the left-hand steer-
ing wheel gearshift paddle (Y page 174).
The automatic transmission shifts down to
the next gear.
If the engine exceeds the maximum engine speed when shifting down, the automatic
transmission protects against engine dam- age by not shifting down.
Automatic downshifting occurs when
coasting.
Gearshift recommendation The gearshift recommendations assist you in
adopting an economical driving style. The rec- ommended gear is shown in the multifunction
display.

Upshifting !
In manual gearshift program
M, the auto-
matic transmission does not shift up auto-
matically even when the engine limiting
speed for the current gear is reached.
When the engine limiting speed is reached, the fuel supply is cut to prevent the engine
from overrevving. You must make sure that the engine speed does not reach the red
area of the rev counter. Otherwise, there is
a risk of engine damage. :

of an accident.
Do not switch off the ignition while driving. ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Con-
sumption can be significantly influenced by
your driving style.
The ECO display consists of three bars:
R Accel.
Accel.
R Constant Constant
R Coasting
Coasting
The percentage count is the mean value of the three bar values. The three bars and the mean
value begin at the value of 50%. A higher per-
centage count indicates a more economical
driving style.
The ECO display does not indicate the actual fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption.
In addition to driving style, the consumption is
affected by many other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers These factors are not included in the ECO dis-
play.
The evaluation of your driving style takes the following three categories into consideration:
R Accel.
Accel. (evaluation of all acceleration pro-
cesses)
- the bar fills up: moderate acceleration,
especially at higher speeds
- the bar empties: sporty acceleration
R Constant Constant (assessment of driving behav-
iour at all times)
- the bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- the bar empties: fluctuations in speed
R Coasting Coasting (assessment of all deceleration
processes)
- the bar fills up: anticipatory driving, keep-
ing your distance and early release of the
accelerator. The vehicle can coast with-
out use of the brakes.
- the bar empties: frequent braking
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
Accel. Accel. andConstant
Constant,
R observe the gearshift recommendation
R drive the vehicle in drive program E
On long journeys at a constant speed, e.g. on the motorway, only the bar for Constant
Constantwill
change.
The ECO display summarises the driving char-
acteristics from the start of the journey to its completion. Therefore, there are dynamic
changes in the bars at the start of a journey.
During a prolonged driving time, these
changes are smaller. For more dynamic
changes, perform a manual reset.

Brakes
Important safety notes G
WARNING
If you shift down on a slippery 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 a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. Take particular note of this when driving a laden vehicle.
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do not park the vehicle immediately. Drive on for
a short while. This allows the airflow to cool
the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective- ness. To do this, brake more firmly from a
higher speed while paying attention to the
traffic conditions. This improves the grip of
the brakes.
Wet road surfaces If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first time. This may also occur after a car wash orafter driving through deep water.
You will have to depress the brake pedal more
firmly. Maintain a greater distance to the vehi-
cle in front.
After driving on a wet road or having the vehi- cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm upthe brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads, a layer of
salt may form on the brake discs and pads.
This can increase the braking distance con-
siderably.
R In order to prevent any salt build-up, apply
the brakes occasionally while paying atten-
tion to the traffic conditions.
R Carefully depress the brake pedal at the
end of the journey and when starting the
next journey.
R Maintain a much greater distance to the
vehicle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres of driving. Compensate for the
reduced braking effect by applying greater
force to the brake pedal. 186

Cruise control
General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. 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 over-
heating and wearing too quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a
steady speed for a prolonged period. You can store any road speed above 30 km/h.
Important safety notes If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control is
only an aid. You are responsible for the dis-
tance to the vehicle in front, for 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 a constant speed, e.g.
in heavy traffic or on winding roads
R on smooth or slippery roads. Braking or
accelerating 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
