Notes on breaking-in a new vehicle
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the happier you will be with its
performance in the future.
R Drive at varying vehicle speeds and engine
speeds for the first 1000 miles (1500 km)
for this reason.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, at the latest
when the tachometer needle is 2
/ 3 of the
way to the red area in the tachometer
display.
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, 2 or 1 when
driving slowly, e.g. in mountainous terrain.
R Ideally, drive program E (on AMG vehicles:
drive program C) should be selected for
driving the first 1000 miles (1500 km).
After 1000 miles (1500 km) you may
gradually bring the vehicle up to full road and
engine speeds.
Additional breaking-in notes for AMG
vehicles:
R For the first 1000 miles (1500 km), do not
exceed a speed of 85 mph (140 km/h).
R Only allow the engine to briefly reach a
maximum engine speed of 4500 rpm.
R Shift gears in good time.
i Also observe these breaking-in notes
when the vehicle's engine or axle gear have
been replaced.
i Always observe the respective limit
speeds.
Driving
Important safety notes
GWarning
Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
GWarning
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.
GWarning
It is dangerous to shift AUTOTRONIC out of
parking position P or neutral position N if the
engine speed is higher than idle speed. If your
foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle
and hit someone or something. Only shift into

Starting procedure with the SmartKey
XTurn the SmartKey to position 3 in the
ignition lock (Y page 267) and release it as
soon as the engine is running.
Using KEYLESS-GO to start the engine
GWarning!
As long as the SmartKey is in your vehicle, the
vehicle can be started. Therefore, never leave
children unattended in the vehicle, as they
could otherwise accidentally start the engine.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Do
not leave children unattended in the vehicle,
or with access to an unlocked vehicle. A
child's unsupervised access to a vehicle could
result in an accident and/or serious personal
injury.
i The Start/Stop button can be used to
start the vehicle without inserting the
SmartKey in the ignition lock. The
SmartKey must be in the vehicle.
XThe Start/Stop button must be inserted in
the ignition lock.

Pulling away
Automatic transmission
GWarning
It is dangerous to shift AUTOTRONIC out of
parking position P or neutral position N if the
engine speed is higher than idle speed. If your
foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and
when your right foot is firmly on the brake
pedal.
i It is only possible to shift the transmission
from position P to the desired position if
you depress the brake pedal. Only then is
the parking lock released. If you do not
depress the brake pedal, you can move the
DIRECT SELECT selector lever but the
parking lock remains engaged.
XDepress the brake pedal and keep it
depressed.XShift the transmission to position D or R.XWait until the gear change is completed
before pulling away.XRelease the brake pedal.XCarefully depress the accelerator pedal.

pulled away. The locking knobs in the doors
drop down.
Driving269Driving and parkingZ

You can open the doors from the inside at
any time.
You can also deactivate the automatic
locking feature .
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll.
GWarning
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your
vehicle and it could roll away.
XTake your foot off the brake pedal.
iOnce you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
XPull away.
Hill start assist will not function if:
Ryou are pulling away on a level road or a
downhill gradient.

Rthe vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
Rincreased sensitivity, which improves
driving stability on slippery road surfaces,
for example
Rthe automatic transmission shifting up
sooner, which results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
In drive program S, the automatic
transmission shifts up later.
