PRE-SAFE®PLUS does not intervene if the
vehicle is backing up.
When driving, or when parking or exiting a
parking space with assistance from Active
Parking Assist, PRE-SAFE
®PLUS will not
apply the brakes.
Function
PRE-SAFE®PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE
®PLUS takes the following meas-
ures depending on the hazardous situation
detected:
Rif the radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
Rif the radar sensor system detects that a
rear-end collision is imminent:
-the brake pressure is increased if the
driver applies the brakes when the vehi-
cle is stationary.
-the seat belts are pre-tensioned.
The PRE-SAFE
®PLUS braking application is
canceled:
Rif the accelerator pedal is depressed when
a gear is engaged
Rif the risk of a collision passes or is no lon- ger detected
Rif DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting in an accident, the original settings
are restored.
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rvehicles with a memory function: the elec-
trically adjustable steering wheel is raised
Rthe engine is switched off and the fuel sup- ply is cut off
Rvehicles with mbrace: automatic emer-
gency call
Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better pro-
tected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
Rbe sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
Rbe sure to observe the instructions and
safety notes on the "Occupant Classifica-
tion System (OCS)" (
Ypage 51)
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
60Children in the vehicle
Safety

Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause Brake Assist to inter-
vene.
If adaptive Brake Assist is not available due to
a malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
ESP
®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP
®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®assists the driver when
pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
ETS traction control is part of ESP
®. On vehi-
cles with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-
vidually 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. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 67).
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
If the å ESP®OFF warning lamp lights up
continuously, ESP®is deactivated.
If the ÷ ESP
®warning lamp lights up con-
tinuously, ESP®is not available due to a mal-
function.
Observe the information on warning lamps
(
Ypage 296) and display messages which
may be shown in the instrument cluster
(
Ypage 258).
Only use wheels with the recommended tire
sizes. Only then will ESP
®function properly.
Characteristics of ESP®
General information
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP
®is automatically
active.
If ESP
®intervenes, the ÷ESP®warning
lamp flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevail-
ing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts automati-
cally when the driver wants to pull away again.

Position of the steering wheel for driv-
ing
The steering wheel is moved to the last selec-
ted position when:
Rthe driver's door is closed and you insert
the SmartKey into the ignition lock
Ryou close the driver's door when the igni-
tion is switched on
Ryou press the Start/Stop button once on
vehicles with KEYLESS-GO
iThe steering wheel only returns to the last
set position if the driving position is stored
after the seat or steering column has been adjusted (
Ypage 122).
The most recent driving position of the steer-
ing wheel is stored if:
Rthe ignition is switched off
Rthe setting is stored with the memory func-
tion (
Ypage 122).
Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened or the SmartKey is removed from the ignition lock. This makes it easier to exit the
vehicle and rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY fea-
ture is activated in Audio 20/COMAND; see
the separate Audio 20/COMAND operating
instructions.

Important safety notes
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten 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
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel
and at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
Rthat are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
iNote that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit into the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as
a status indicator in the instrument cluster.
When a parking space h
as been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv- er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the
a
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) awayfrom it .
Parking
GWARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.
iWhen PARKTRONIC detects obstacles,
Active Parking Assist brakes automatically

MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking next to the tire size designation, the load-
bearing capacity and the speed index
(
Ypage 389).
MOExtended tires may only be used in con-
junction with an active tire pressure monitor.
If a pressure loss warning message
appears in the multifunction display:
Robserve the instructions in the display mes-
sages (
Ypage 285).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden. When the vehicle is
fully laden it is approximately 19 miles
(30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon:
Rvehicle speed
Rroad condition
Routside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions or maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the multifunction dis-
play.
You must not exceed a maximum speed of
50 mph (80 km/h). When replacing one or all tires, please
observe the following specifications for your
vehicle's tires:
Rsize
Rthe type and
Rthe "MOExtended" mark
If a tire has gone flat and cannot be replaced
with a MOExtended tire, a standard tire may
be used as a temporary measure. Make sure
tha

t you use the proper size and type (sum-
mer or winter tire).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qualified specialist work-
shop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.

There is a risk of accident.
Tires without run-flat characteristics:
Rdo not drive with a flat tire.
Rimmediately replace the flat tire with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tires with run-flat characteristics:
Rpay attention to the information and warn-
ing notices on MOExtended tires (tires with
run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Information on the sizes and types of wheels
and tires for your vehicle can be found under "Wheel/tire combinations" (

Operation
Information on driving
Check the tire pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires
and wheels checked at a qualified specialist
workshop.
374Operation
Wheels and tires

approximatelyáin(1.6 mm )ha sbeen
re ached. If this is the case, the tire is so worn
that it must be replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same
type and make.
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(
Ypage 357).
ROnly mount tires of the correct size onto
the wheels.
RBreak in new tires at moderate speeds for
the first 60 miles (100 km). They only reach
their full performance after this distance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
RReplace the tires after six years at the lat-
est, regardless of wear.
MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires.
MOExtended tires may only be used in con-
junction with an active tire pressure monitor
and only on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tires with
a flat tire (
Ypage 357).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit can be obtained from a qualified specialist work-
shop.
Winter operation
General notes
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
Observe the notes in the "Changing a wheel"
section (
Ypage 395).
Driving with summer tires
At temperatures below 45
‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use win-
ter tires or all-season tires. Both types of tire
are identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking pro-
376Winter operation
Wheels and tires

There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning a long journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here
are examples. Tire pressure specifications
are vehicle-specific and may deviate from the data shown here. The tire pressure specifica-
tions that are valid for your vehicle can be
found on the Tire and Loading Information
placard and tire pressure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Operation with a trailer: the applicable
value for the rear axle is the maximum tire
pressure value stated in the table inside the
fuel filler flap.
Further information on tire pressures can be
obtained at a qualified specialist workshop.
Tire and Loading Information placard
:Recommended tire pressures The Tire and Loading Information placard is
on the B-pillar on the driver's side
(
Ypage 384).
The Tire and Loading Information placard con-
tains the recommended tire pressures for
cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehicle
speed.
Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap. It shows the tire pressure for all
tires permitted at the factory for this vehicle; see illustration (example).
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid
for that tire size; see illustration (example).
