restraint supports the back of the head at
about eye level.
Make sure that you do not rotate the head
restraints of the front and rear seats when
adjusting the head restraints. Otherwise, you cannot adjust the height and angle of the
head restraints correctly.
Adjust the head restraint so that it is as close as possible to your head.
GWARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop- erly secured in an appropriately sized child
restraint system or booster seat recommen-
ded for the size and weight of the child. For
additional information, see the "Children in
the vehicle" section.
A child's risk of serious or fatal injuries is sig-
nificantly increased if the child restraints are
not properly secured in the vehicle and/or the child is not properly secured in the child
restraint.
!To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools. The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate- rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
!Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
!When the rear bench seat is folded for-
wards, the front seats cannot be moved to their rearmost position. You could other-
wise damage the seats and the rear bench
seat.
!Make sure that the sun visor is folded up
before adjusting the backrest and head
restraint height. The head restraint and sun visor could otherwise collide when the head
restraint is fully extended.
iIf the front door is open, the seats can be
adjusted for up to 30 minutes after the igni- tion has been switched off.
iThe rear-compartment head restraints
can be removed ( Ypage 84).

Rear seat head restraints
Important safety notes
GWARNING
If head restraints are not installed and adjus-
ted correctly, they cannot provide protection
as intended. There is an increased risk of
injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Observe the following when adjusting the
head restraints: X Do not rotate the head restraints of the
front and rear seats.
Otherwise, you cannot adjust the height
and angle of the head restraints correctly.
X Adjust the head restraint so that it is as
close as possible to your head.

Switching the seat heating on/off
General notes
GWARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to excessively high tempera-
tures may be affected or they may even suffer burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.

General information
The manual drive program is only available on AMG vehicles . In manual drive program M,
you can permanently change gear yourself by
using the steering wheel paddle shifters. The
transmission must be in position D. The gear
currently selected and engaged is shown in
the multifunction display.
Manual drive program Mdiffers from drive
programs Eand Swith regard to spontaneity,
responsiveness and smoothness of gear
changes.
Switching on the manual drive program
X Shift the transmission to position D.
X Press the program selector button repeat-
edly until Mappears in the multifunction
display, see Digital Operator's Manual.
Upshifting
!In manual drive program M, the automatic
transmission does not shift up automati-
cally 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. Always make sure that the
engine speed does not reach the red area of
the tachometer. There is otherwise a risk of
engine damage.
X If relevant gearshift recommendation :
appears in the multifunction display on the instrument cluster, pull on the right-hand
steering wheel paddle shifter (see the Dig-
ital Operator's Manual).

incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.

Driving and pa rking
Z
Do not place your foot under the brake pedal.Keep the area under the brake pedal free from
obstructions.
If you fail to adapt your driving style, cruise
control can neither reduce the risk of acci-
dent nor override the laws of physics. Cruise
control cannot take account of road, weather and traffic conditions. Cruise control is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed and for braking in good time. Adjust your driving style to the traffic conditions. Only engage cruise
control when the current road, weather and
traffic conditions permit it to be done safely.
Drive carefully and maintain a suitable dis-
tance to the vehicle in front.
Do not use cruise control: R in traffic conditions that do not allow you to
drive at a constant speed, e.g. heavy traffic,
on winding roads or off-road
R on slippery road surfaces. Braking or accel-
erating could 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
General notes
Cruise control maintains a constant road
speed for you. On long and steep downhill
gradients, especially if the vehicle is laden,
you must select shift range 1,2 or 3in good
time. 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 overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can store any road speed above 20 mph
(30 km/h).
iCruise control should not be activated
when driving off-road.

SPEEDTRONIC
Important safety notes
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of acci-
dent nor override the laws of physics. SPEED- TRONIC cannot take account of road, weather
and traffic conditions. SPEEDTRONIC is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for
braking in good time and for staying in lane.
Only engage SPEEDTRONIC when the current road, weather and traffic conditions permit it
to be done safely. Drive carefully and main-
tain a suitable distance to the vehicle in front.
General notes
SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. On long andsteep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2 or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. If
you need additional braking, depress the
brake pedal repeatedly rather than continu-
ously.

time and for staying in your lane. Only engage
DISTRONIC PLUS when the current road,
weather and traffic conditions permit it to bedone safely, and adapt your driving style
accordingly. Drive carefully and maintain a
suitable distance to the vehicle in front.
When DISTRONIC PLUS detects a risk of col-
lision with the vehicle in front but is unable to
sufficiently decelerate the vehicle in order to
maintain the set distance from the vehicle in
front, you will be warned visually and acous-
tically. DISTRONIC PLUS cannot prevent a
collision without your intervention. An inter-
mittent warning tone will then sound and the distance warning lamp will light up in the
instrument cluster. Brake immediately in
order to increase the distance from the vehi-
cle in front, or take evasive action, provided it
is safe to do so.
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line. Therefore,
always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognize dangers
in time, cause an accident and injure yourself and others.
In particular, the detection of obstacles can
be impaired if:
R the sensor is dirty or covered
R there is snow or heavy rain
R there is interference by other radar sources
R there is the possibility of strong radar
reflections, for example, in parking
garages.
If DISTRONIC PLUS is activated, the vehicle
brakes automatically in certain situations.
This can happen unexpectedly, especially
when towing or in a car wash. There is a risk of an accident. In these or similar situations,
deactivate DISTRONIC PLUS.
If you want DISTRONIC PLUS to assist you,
the following activation conditions must be
fulfilled ( Ypage 119) and the radar sensor
system must be operational.General notes
DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so
that the set speed is not exceeded.
On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range 1,2 or 3in good
time. 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 overheating and wearing too
quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order
to maintain the preset distance to the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and 120 mph (Canada:
200 km/h). If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it
can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.
