EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to
improve handling during braking.
Important safety notes Observe the important safety guidelines for
the driving safety system
(Y page 66).G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases
the risk of skidding and an accident.
You should therefore adapt your driving
style to the different handling characteris-
tics. Have the brake system checked at a
qualified specialist workshop.
If EBD is malfunctioning, the $ warning
lamp

(Y page 229) lights up while the engine
is running and the display shows a message:
R on vehicles without steering wheel buttons
(Y page 199)
R on vehicles with steering wheel buttons
(Y page 213)
Other driving systems and driving safety sys-
tems then also fail. ESP
®
(Electronic Stability Program)
General notes ESP
®
monitors driving stability and detects a
tendency of the vehicle to understeer or over-
steer (skidding) in good time. 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 out-
put is also modified to keep the vehicle on the
desired course within physical limits. ESP ®
can
also stabilize the vehicle during braking.
ESP ®
also monitors traction, i.e. power trans-
mission between the tires and the road sur-
face. The integrated traction control supports
you when pulling away or accelerating on wet,
slippery or slick roads. Should the drive
wheels spin, traction control brakes them indi- vidually. In addition, greater drive torque is
transmitted to the wheel or wheels with trac-
tion. If traction on the road surface is not suffi-
cient, even ESP
®
will not allow you to pull
away without difficulty. The type of tires and
total weight of the vehicle as well as the gradi-
ent of the road also play a crucial role. Trac-
tion control remains active if you deactivate
ESP ®
.
If the h warning lamp in the instrument
cluster goes out before beginning the journey,
ESP ®
is automatically active.
The h warning lamp in the instrument clus-
ter flashes when ESP ®
intervenes:
X do not deactivate ESP ®
under any circum-
stances.
X when driving off, apply as little throttle as
possible.
X adapt your speed and driving style to the
prevailing road conditions.
Important safety notes Observe the important safety guidelines for
the driving safety system (
Y page

66). G
WARNING
If ESP ®
is malfunctioning it will not provide
any vehicle stabilization. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP ®
checked at a qualified specialist
workshop.
! Do not run the vehicle on a roller dyna-
mometer (e.g. for performance tests). If you
must operate the vehicle on a roller dyna-
mometer, please consult a qualified special-
ist workshop in advance. You could other-
wise damage the drive train or the brake
system.
If ESP ®
is malfunctioning, the h warning
lamp

(Y page 230) lights up continuously
while the engine is running and the display
shows a message.

ESP
®
is deactivated if the å warning lamp
in the instrument cluster is lit when the engine
is running.
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
Deactivating or activating ESP ®G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
Activate ESP ®
as soon as the situations descri-
bed above no longer apply. Otherwise, ESP ®
assistance for stabilizing the vehicle will
remain significantly reduced, even if the vehi-
cle starts to skid.
If you deactivate ESP ®
:
R the å warning lamp in the instrument
cluster lights up
R the ÷ warning lamp in the instrument
cluster flashes if the wheels are spinning
R ESP ®
assistance for stabilizing the vehicle in
the lower speed range up to approximately
37 mph (60 km/h
) is significantly reduced
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in a cutting action for
better traction on loose surfaces
R traction control is still activated
R ESP ®
still provides support when you brake
Depending on the equipment in the vehicle,
you can activate or deactivate ESP ®
when the
engine is running by using the å button or
by using the on-board computer:
R on vehicles without steering wheel buttons
(Y page 179)
R on vehicles with steering wheel buttons
(Y page 190) å button (equipment-dependent)
X To activate/deactivate: when the engine
is running, press the å button.
The å warning lamp in the instrument
cluster lights up when ESP ®
is deactivated.
Trailer stabilization Observe the important safety guidelines for
the driving safety system (
Y page

66). G
WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to pre-
vent the vehicle/trailer combination from
swerving. Trailers with a high center of grav-
ity can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt your driving style to the pre-
vailing road and weather conditions.
ESP ®
trailer stabilization counteracts critical
driving situations in good time and thereby
provides considerable assistance when driving
with a trailer. Trailer stabilization is part of
ESP ®
.
If the sensor system and evaluation logic
detect trailer swinging movements, ESP ®
trailer stabilization firstly brakes individual
vehicle wheels in a targeted manner. It thus
counteracts swinging movements. If the
swinging movements do not stop, the vehicle
is braked until the vehicle/trailer combination
is stabilized. If necessary, the vehicle's engine
output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilize the vehicle/trailer combination only
by braking. ESP ®
trailer stabilization helps you Driving safety systems

Mounting a new wheel
G
WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the
wheel bolts to come loose. As a result, you
could lose a wheel while driving. There is a
risk of accident.
Never oil or grease wheel bolts. In the event
of damage to the threads, contact a quali-
fied specialist workshop immediately. Have
the damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving. G
WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always observe the instructions and safety
notes on "Changing a wheel"
(Y page 297).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz vehicles and the
respective wheel.
! On vehicles equipped with a tire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at a qualified spe-
cialist workshop. X
Clean the wheel and wheel hub contact sur-
faces.
X Slide the new wheel onto the wheel hub and
push it on.
X Screw in the wheel bolts and tighten them
lightly.
Lowering the vehicle G
WARNING
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed tightening torque. There is a risk
of an accident.
Ensure that the wheel bolts or wheel nuts
are tightened to the prescribed tightening
torque.
If you are not sure, do not move the vehicle.
Contact a qualified specialist workshop and
have the tightening torque checked immedi-
ately. :—A

Turn the jack back to its out-of-use position.
X Stow the jack and the rest of the tire-
change tool kit in the vehicle again.
X Wheel with hub cap: position the opening
for the tire valve in the hub cap over the tire
valve.
X Push the edge of the hub cap with both
hands against the wheel until it clicks into
place. Make sure the hub cap retaining
catches engage on the steel wheel.
X If included in the vehicle equipment, secure
the faulty wheel in the spare wheel bracket
(Y page
303). Otherwise, transport the
faulty wheel in the cargo compartment.
X Check the tire pressure of the newly moun-
ted wheel and adjust it if necessary.
Observe the recommended tire pressure
( Y page

282).
Vehicles with the tire pressure monitor sys-
tem: all mounted wheels must be equipped
with functioning sensors.
X Retighten the wheel bolts or wheel nuts to
the specified tightening torque after the
vehicle has been driven for

30 miles
(50 km).
When using a wheel/spare wheel with a new
or newly painted wheel rim, have the wheel
bolts/nuts retightened again after approx-
imately

600 to 3,000 miles (1,000 to
5,000 km). Observe the specified tightening
torque. Wheel and tire combinations
General notes
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tires. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires
if you have no information about their previ-
ous usage.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tires, wheels and accessories which have been approved by
Mercedes-Benz specifically for your vehicle.
These tires have been specially adapted for
use with the driving safety systems, such as
ABS or ESP
®
.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition,
when driving with a load, tire dimension var-
iations could cause the tires to come into
contact with the bodywork and axle compo-
nents. This could result in damage to the
tires or the vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels
or accessories other than those tested and
approved.
Further information on wheels, tires and
approved combinations can be obtained
from a qualified specialist workshop.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tires as a result of driving over obstacles
increases.
You will find a table with the recommended
tire pressures for various vehicle loads on the
inside of your vehicle's fuel filler flap or under
"Tire pressure tables"

(Y page 289). You can
find further information under "Tire pressure"
( Y page 282).
Check tire pressures regularly and only when
the tires are cold.
Notes on the vehicle equipment – always
equip the vehicle:
R with tires of the same size across an axle
(left/right)
R with the same type of tires on all wheels at
a given time (summer tires, winter tires)
i Not all wheel/tire combinations can be
installed at the factory in all countries. Wheel and tire combinations
