After the seat backrest has been folded back,
check the position of the head restraint and
set it to the correct position.
X Seat with memory function: swing back the
seat backrest horizontally.
If the seat backrest is not engaged, this will be
shown on the multifunction display on the
instrument cluster. A warning tone also
sounds.
The seat moves automatically to the stored
position.

ment position. G
WARNING
If the backrest is not engaged, it could fold
forwards during a braking manoeuvre or in the event of an accident, for example. The seat
backrest will then push the vehicle occupant
against the seat belt. The seat belt cannot
protect as intended and could result in addi-
tional injury. This poses an increased risk of
injury.

WARNING
If you use the memory function on the driver's side while driving, the adjustments could
cause you to lose control of the vehicle. There
is a risk of an accident.
Only use the memory function on the driver's
side while the vehicle is stationary. G
WARNING
When the memory function adjusts the seat or steering wheel, you and other vehicle occu-
pants – particularly children – could become
trapped. There is a risk of injury.
While the memory function is making adjust-
ments, make sure that no one has any body
parts in the sweep of the seat or steering
wheel. If somebody becomes trapped, imme-
diately release the memory function position
button. The adjustment process is stopped. G
WARNING
If children activate the memory function, they
could become trapped, especially if they are
unattended. There is a risk of injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
The memory function can be used at any time,
e.g. even when the key is not in the ignition lock. Storing settings
Using the memory function, you can store up to three different settings, e.g. for three different
people.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
R driver's side: position of the exterior mirrors
on the driver's and front-passenger sides
R position of the head-up display X
Adjust the seat accordingly (Y page 102).

If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf- fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflectionsis thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic conditions.
In particular, the detection of obstacles can be
impaired in the case of:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or obscured sensors Switching Adaptive Highbeam Assist
Plus on/off X
To switch on: turn the light switch to the

The indicator lamp _on the multifunction
display lights up when it is dark and the light
sensor switches on the dipped-beam head-
lamps.
At speeds above approx. 25 km/h: the head- lamp range is automatically controlled
according to the distance to other road users.
At speeds above approximately 30 km/h:
R if no other road users are detected, the
main-beam headlamps are automatically
switched on
R if other road users are detected, the partial
main-beam headlamps are automatically
switched on
The K indicator lamp on the instrument
cluster also lights up.
At speeds below approx. 25 km/h or when
there is sufficient street lighting:
R the partial main-beam headlamps are
switched off automatically
R the main-beam headlamps are switched off
automatically
The K indicator lamp on the instrument
cluster goes out. The _indicator lamp on
the multifunction display remains lit.
X To switch off:move the combination switch

Running-in notes
Important safety notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective-
ness is not reached until the end of this teach-in process.
Brake pads/linings and discs that either are new or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. The first 1500 km
The more you treat the engine with sufficient
care at the start, the more satisfied you will be
with the engine performance later on.
R You should therefore drive at varying road
speeds and engine speeds for the first
1500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When shifting gears manually, shift up in good
time, before the rev counter needle reaches
Ô of the way to the red area of the rev counter
display.
R Do not shift down a gear manually in order to
brake.
R Vehicles with automatic transmission: try to
avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
Additional notes on running in Mercedes-AMG
vehicles:
R Do not drive at speeds above 140 km/h for
the first 1500 km.
R Allow the engine to reach a maximum engine
speed of 4500 rpm only briefly.
R Drive the vehicle mainly in drive program Cfor
the first 1500 km.
After 1500 km, you can increase the engine
speed gradually and accelerate the vehicle to
full speed.
You should also observe these notes on running- in if the engine or parts of the drive train on your
vehicle have been replaced. Always observe the maximum permissible
speed. Self-locking rear axle differential
(Mercedes-AMG vehicles)
Your vehicle is equipped with a self-locking dif-
ferential on the rear axle.
Change the oil to improve protection of the rear
axle differential:
R after a running-in period of 3000 km
R every 50,000 km or 3 years
These oil changes prolong the service life of the
differential. Have the oil change carried out at a
qualified specialist workshop. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell can impede
pedal travel or block a pedal which is
depressed. This jeopardises safe operation of the vehicle. There is a risk of an accident.
Stow all objects in the vehicle safely, so that
they cannot reach the driver's footwell. Make sure the floormats and carpets are properly
secured so that they cannot slip and obstruct the pedals. Do not lay several floormats or
carpets on top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, 132

the engine running in enclosed spaces with-
out sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
