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) i
Observe the "Important safety notes" sec-
tion (Y page 76).
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 G
WARNING
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.
Vehicles without 4MATIC: observe the notes
on ESP ®
(Y page 437) when towing the vehi-
cle with a raised rear axle.
ESP ®
is only deactivated if the åwarning
lamp is lit continuously.
If the ÷ warning lamp lights up continu-
ously, ESP ®
is not available due to a malfunc-
tion.
Observe the information on warning lamps
(Y page 360) and display messages which
may be shown in the instrument cluster
(Y page 317). 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:
X Do not deactivate ESP ®
under any circum-
stances.
X Only depress the accelerator pedal as far as
necessary when pulling away.
X Adapt 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. ESP ®
remains in its previously selected sta-
tus. Example: if ESP®
was deactivated before
the engine was switched off, ESP ®
remains
deactivated when the engine is switched on
again.
Deactivating/activating ESP ® Important safety notes
i Observe the "Important safety notes" sec-
tion (Y page 76).
You can select between the following states
of ESP ®
:
R ESP ®

Pedestrian and animal recognition
General notes
Pedestrian or animal recognition may be
impaired or inoperative if:
R pedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
R the silhouette of the pedestrian or of the
animal in the Night View Assist Plus display
is incomplete or interrupted, e.g. by pow-
erful light reflections
R pedestrians or animals do not contrast with
the surroundings
R the camera system no longer recognizes
pedestrians as persons due to special
clothing or other objects
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying
R animals are not recognized by the system,
e.g. because of their size or shape
The pedestrian and animal recognition is
deactivated at temperatures above 90 ‡ (32 †). The spotlight function and automatic
delayed switch-off are then no longer active.
Pedestrian recognition :

? Pedestrian recognized
Night View Assist Plus can recognize pedes-
trians using typical characteristics, e.g. the body contours and posture of a person stand-
ing upright.
Pedestrian recognition is then switched on
automatically if:
R Night View Assist Plus is activated.
R you are driving faster than approximately
6 mph (10 km/h).
R it is dark.
If pedestrian recognition is active, readiness
symbol ;appears. Persons who are detec-
ted are highlighted by framing =. If the
pedestrian recognition system has brought a pedestrian to your attention, look through the
windshield to evaluate the situation. The
actual distance to objects and pedestrians
cannot be gaged accurately by looking at a
screen.
Animal recognition
Animals can be recognized in the following
situations:
R darkness
R outside built-up areas
R below an outside temperature of 90 ‡
(32 †)
Night View Assist Plus can recognize larger
animals such as deer, cows or horses using
typical characteristics.
The system does not detect:
R smaller animals, e.g. dogs and cats
R animals whose silhouette is not clearly rec-
ognizable.
When detected, animals are marked with
small color frame corners. In contrast to
pedestrian recognition, there is no separate
readiness symbol in the multifunction dis-
play. Driving systems

X All occupants must get out of the vehicle.
Make sure that they are not endangered as they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier. X
Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door. 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
(Y page 459).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressure loss warning message
appears in the multifunction display:
R Observe the instructions in the display
messages (Y page 348).
R Check the tire for damage.
R If driving on, observe the following notes.
The maximum driving distance is approx-
imately 50 miles (80 km) when the vehicle is
partially laden and approximately 18 miles
(30 km) when the vehicle is fully laden.
In addition to the vehicle load, the driving dis- tance possible depends upon:
R Speed
R Road condition
R Outside temperature
The driving distance possible in run-flat mode may be reduced by extreme driving condi-
tions/maneuvers, or it can be increased
through a moderate style of driving. Flat tire
423Roadside Assistance

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).
i When replacing one or all tires, make sure
that you use only tires:
R of the size specified for the vehicle and
R marked "MOExtended"
If a tire has gone flat and cannot be
replaced with a MOExtended tire, a stand-
ard tire may be used as a temporary meas- ure. Make sure that you use the proper size
and type (summer or winter tire).
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally 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 quali- fied specialist workshop.
Important safety notes G
WARNING
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:
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 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. TIREFIT kit
Important safety notes TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tem-
peratures down to Ò4 ‡ (Ò20 †). G
WARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis- tance, as it is unable to seal the tire properly:
R there are cuts or punctures in the tire larger
than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tire pressures or
on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop. G
WARNING
The tire sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tire sealant away
from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
R Rinse off the tire sealant from your skin
immediately with water.
R If the tire sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately. 424

Information on driving
If the vehicle is heavily loaded, check the tire pressures and correct them if necessary.
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. 442

reached. If this is the case, the tire is so worn
that it must be replaced. Selecting, mounting and replacing
tires
R Only 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
(Y page 423).
R Only mount tires of the correct size onto
the wheels.
R Break in new tires at moderate speeds for
the first 60 miles (100 km). They only reach
their full performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace 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 loss
warning system or with an active tire pressure monitor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tires with
a flat tire (Y page 423).
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally 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 quali-
fied specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 465). 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. G
WARNING
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
G
WARNING
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

The specifications on the sample Tire and
Loading Information placard and tire pres-
sure tables are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure 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.
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
(Y page 453).
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. Example: tire pressure table for all tires permitted
for this vehicle by the factory
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions. Example: tire pressure table with tire dimensions
If a tire size precedes a tire pressure, the tirepressure information following is only valid
for that tire size. The load conditions "partially
laden" and "fully laden" are defined in the
table for different numbers of occupants and
amounts of luggage. The actual number of
seats may differ. 446
Tire pressureWheels and tires

Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18 . The rim diameter is part of the tire size
and can be found on the tire sidewall
(Y page 459).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset to the higher values:
R if you want to drive with an increased load
and/or
R if you want to drive at higher road speeds
i The tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build up of heat and
a sudden loss of pressure.
For more information, contact a qualified spe- cialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident. R Check the tire for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop. G
WARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also result in tire pressure loss. There is a
risk of an accident. Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitor, the tire
pressure can be checked in the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend- ent on the driving speed and the load.
Therefore, you should only correct tire pres-
sures when the tires are cold.
The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡ (10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into account when check-
ing the pressure of warm tires. Only correct
the tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result- ing value will be higher than if the tires were
cold. This is normal. Do not reduce the tire
pressure to the value specified for cold tires.
The tire pressure would otherwise be too low.
Observe the recommended tire pressures for
cold tires:
