Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 25).Notes on breaking-in
anew vehicle Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1,000miles (1,500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1,000 miles (1,500 km).
R Ideally, for the first 1,000 miles (1,500 km),
drive in program E(for AMG vehicles drive
program C).
R Avoid heavy loads, e.g .driving at full
throttle, during this period.
R Change gearing ood time, before the
tachometer needle is 0001of the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle. R
If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Only select shift ranges 3,2or 1when
driving slowly, e.g. in mountainous terrain.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and
accelerate the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
R Do not drive faster than 85 mph
(140 km/h) for the first 1000 miles
(1500 km).
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
i You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
i Always observe the respective speed
limits. AMG vehicles with self-locking rear
axle differential
Your vehicle is equipped with aself-locking
differential on the rear axle. Change the oil
after a breaking-in period of 2,000 miles
(3,000 km) to improve protection of the rear
axle differential. This oil change prolongs the
service life of the differential. Have the oil
change carried out at a qualified specialist
workshop. Driving

WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct adepressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident. 140
DrivingDriving and parking

!
Always secure the vehicle correctly
against rolling away. Otherwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied.
R the transmission must be in position Pand
the SmartKey must be removed from the
ignition lock.
R on uphill or downhill gradients, the front
wheels must be turned towards the curb. Switching off the engine
Important safety notes G
WARNING
The automatic transmission switches to
neutral position Nwhen you switch off the
engine. The vehicle may roll away. There is a
risk of an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked
vehicle from rolling away by applying the
parking brake.
Vehicles with automatic transmission X
Apply the parking brake firmly.
X Shift the transmission to position P.
Using the SmartKey
X Turn the SmartKey to position 0in the
ignition lock and remove it.
The immobilizer is activated.
i The SmartKey can only be removed if the
transmission is in position P.
Using KEYLESS-GO
X Press the Start/Stop button (Y page 142).
The engine stops and all the indicator
lamps in the instrument cluster go out.
i When the driver's door is closed, this
corresponds to key position 1. When thedriver's door is open, this corresponds to
key position
0:"key removed".
If you try to switch off the engine when the
transmission is not in position P, a message
appears in the multifunctio ndisplay. Asignal
sounds. Parking brake
G
WARNING
If you must brake the vehicle with the parking
brake, the braking distanc eis considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's
equipment. There is a risk 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.
If you brake the vehicle with the parking
brake, the brake lamps will not light up. Parking
159Driving and parking Z

X
Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning .There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Ben
zservice requirements. Details
can be found in the Maintenance Booklet. ECO display
The ECO display gives you information on how
economical your driving style is. The ECO
display assists you in achieving the optimum
driving style in terms of consumption, taking
the actual and selected conditions into
consideration .Your driving style can
significantly influence the vehicle's
consumption. Example: ECO display
The ECO display consists of three bars:
R
Acceleration R
Constant R
Coasting The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%.
Ahigher
percentage indicates a mor eeconomical
driving style.
The ECO display does not indicate the actual
fuel consumption and a fixed percentage
count in the ECO display does not indicate a
fixed consumption figure.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
R load
R tire pressure
R cold start
R choice of route
R electrical consumers switched on Driving tips
