! Vehicles with 4MATIC: switch off the
ignition when the electric parking brake is
being tested on a brake dynamometer.
Application of the brakes by ESP ®
may
otherwise destroy the brake system.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System)GWarning
Observe "Important safety notes"
( Y page 66).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. On vehicles with 4MATIC, more
drive torque is also transferred to the wheel
or wheels with traction.
Traction control remains active if you
deactivate ESP ®
.
Activating/deactivating ESP ®
GWarning!
The ESP should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP when a spare wheel
is mounted.
GWarning
S 63 AMG: ESP ®
should not be deactivated
during normal driving.
Deactivating the system results in the
following:
R no restriction to the engine torque
R loss of system-supported traction control
"ESP OFF" is designed for driving on closed
tracks when the vehicle's own oversteering
and understeering characteristics are desired
and requires an extremely qualified and
experienced driver who is able to handle
these critical driving situations.
You could lose control of your vehicle and
cause an accident.
Beware of these limits if you deactivate
ESP ®
.
Do not deactivate ESP ®
when the emergency
or spare wheel is mounted.
ESP ®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravelGWarning!
Switch on the ESP immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
When you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ warning lamp in the
instrument cluster flashes. In such situations,
ESP ®
will not stabilize the vehicle.
XTo deactivate: (Y page 375).

cluster lights up.70Driving safety systemsSafety

Seats
Important safety notes
GWarning
In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel and rear view mirror adjustments, as
well as fastening of seat belts, must be done
before setting the vehicle in motion.
GWarning
Do not adjust the driver's seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never travel in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belts
provide the best restraint when the wearer is
in a position that is as upright as possible and
seat belts are properly positioned on the
body.
GWarning
Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
Observe the following points:
R adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level.
R never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.GWarning
The electrically adjustable seats can be
operated at any time. Therefore, 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.
GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see "Children in the vehicle".
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
GWarning
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.

inside of the fuel filler flap of your vehicle, if there is one). If your vehicle has tires which are a
different size to those on the tire and load data label or those specified in the tire pressure table,
if there is one, you should determine the correct tire pressure for these tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitor (TPMS).
An indicator lamp lights up if one or more of your tires are significantly underinflated. Accordingly,
when the low tire pressure indicator lamp lights up, you should stop and check your tires as soon
as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
An excessively low tire pressure also increases fuel consumption, reduces the service life of the
tires and may impair the driving and braking characteristics of the vehicle. Please note that the
TPMS is not a substitute for proper tire maintenance and it is the driver's responsibility to maintain
correct tire pressure, even if underinflation has not reached the level at which the low tire
pressure indicator lamp of the TPMS lights up.
USA only:
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure indicator lamp. When the system detects a malfunction, the indicator lamp will flash
for approximately one minute and then remain illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator
is lit, the system may not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction indicator after replacing one or more tires or wheels
on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.420Warning and indicator lamps in the instrument clusterOn-board computer and displays

Preparing the vehicleGWarning
The wheel and tire size of the emergency
spare wheel/spare wheel may differ to that of
the damaged wheel. When using an
emergency spare wheel/spare wheel the
handling characteristics of the vehicle may
change.
Adapt your style of driving accordingly.
Never operate the vehicle with more than one
emergency spare wheel/spare wheel that
differs in size.
Only use an emergency spare wheel/spare
wheel of a differing size briefly and do not
switch off ESP ®
.
When using an emergency spare wheel, you
must not exceed the maximum speed of
50 mph (80 km/h).
GWarning
Have the different-sized emergency spare
wheel/spare wheel replaced with a new
wheel as soon as possible at a qualified
specialist workshop that has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose. In
particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
i Vehicles without an emergency spare
wheel/spare wheel are not equipped with
a tire-change tool kit at the factory. For
more information on which tools are
required to perform a wheel change on your
vehicle, e.g. wheel chock, alignment bolt,
or lug wrench, consult an authorized
Mercedes-Benz Center.
Flat tire463Roadside assistanceZ

The maximum permissible distance which
can be driven in run-flat mode depends on the
cargo in the vehicle. You can drive 50 miles
(80 km) if the vehicle is partially laden and
18 miles (30 km) if it is fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
50 mph(80 km/h).GWarning!
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. curbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
extent on the loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
cargo, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you drive carefully and
conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tire.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at a
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. The faulty tire
must be replaced in every case.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.
i When replacing one or all tires, make sure
that you only use tires marked
MOExtended and of the specified size for
the vehicle.
Battery
Important safety notes
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
! Have the battery checked regularly at a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
Observe the service intervals in the Service
Booklet or for further information consult a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
Have the battery charge checked more
frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for
a lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz.
Consult an authorized Mercedes-Benz Center
if you wish to leave your vehicle parked up for
a long period of time.
GWarning
Hybrid vehicles: ensure that you read the
"HYBRID" supplement. You may otherwise fail
to recognize dangers.
GWarning

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Important safety notes
Contact an authorized Mercedes-Benz Center
if you require information on tested and
recommended tires and wheels for summer
and winter driving. Advice on purchasing and
caring for tires is also available there.
GWarning
Replace rims or tires with the same
designation, manufacturer and type as shown
on the original part. For further information
contact an authorized Mercedes-Benz Center.
If incorrectly sized rims and tires are
mounted, the wheel brakes or suspension
components can be damaged. Also, the
operating clearance of the wheels and the
tires may no longer be correct.
GWarning
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result
in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or
recommended by Mercedes-Benz, since
previous damage cannot always be
recognized on retreads. The operating safety
of the vehicle cannot be assured when such
tires are used.
GWarning
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle appears
unsafe, have the vehicle towed to the nearest
authorized Mercedes-Benz Center or tire
dealer for repairs.
GWarning
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
might lose control of the vehicle. Continued
driving with a flat tire or driving at high speed
with a flat tire will cause excessive heat build-
up and possibly a fire.
i Further information about tires and
wheels can be obtained from any
authorized Mercedes-Benz Center.
Mode
Notes on driving
R If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary.
R When parking your vehicle, make sure that
the tires do not get deformed by the curb
or other obstacles. If it is necessary to drive
over curbs, speed humps or similar
elevations, try to do so slowly and at an
obtuse angle. Otherwise, the tires –
particularly the sidewalls – can get
damaged.
Notes on regularly inspecting wheels
and tires
GWarning
Regularly check the tires for damage.
Damaged tires can cause tire inflation
