the trailer from swerving and will thus be
unable to reduce the risk of an accident. Trail-
ers with a high centre of gravity can tip over
before ESP ®
can detect this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function.
Activating/deactivating ESP ®ESP
®
is activated automatically when the
engine is running.
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 G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If 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. 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.
i If ESP ®
is deactivated and one or more
wheels start to spin, the dwarning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilise the vehi-
cle. X
To deactivate: press button:.
The d warning lamp in the instrument
cluster lights up. G
Risk of accident
If the d warning lamp in the instrument
cluster is continuously lit when the engine is
running, ESP ®
is deactivated or not available
due to a malfunction. There is an increased
risk of your vehicle skidding in certain situa-
tions.
You should always adapt your driving style to
suit prevailing road and weather conditions.
X To activate: press button :.
The d warning lamp in the instrument
cluster goes out.
Off-road ESP ® An ESP
®
system specifically suited to off-road
terrain is activated automatically if the LOW
RANGE off-road gear (Y page 114) is selec-
ted. It intervenes with a delay if there is over-
steering or understeering, thus improving
traction. EBV (electronic brake force distribu-
tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability when braking. 52

DSR switches off automatically if you drive
faster than 35 km/h. The DSR symbol
appears in the multi-function display with the
Off message. You also hear a warning tone.
Changing the set speed while the vehi-
cle is in motion When DSR is activated, you can change the
set speed to a value between 4 km/h and
18 km/h while the vehicle is in motion. X
To increase or reduce the set speed by
1 km/h increments: briefly press the
cruise control lever to the pressure point,
up : for a higher set speed or down ;for
a lower set speed.
The set value appears in the multi-function

The LOW RANGE off-road gear assists you in
driving off-road and when fording. When LOW
RANGE is engaged, the engine’s performance
characteristics and the gearshifting charac-
teristics of the automatic transmission are
adapted for this purpose. ABS, ESP ®
and
4ETS programs especially adapted to off-road
driving are also activated. You will find infor-
mation about driving off-road in the "Opera-
tion" section (Y page 188). You will find infor-
mation about driving safety systems in con-
junction with LOW RANGE in the "Safety" sec-
tion (Y page 49).
Shift ranges HIGH RANGE
Road position for all nor-
mal driving situations
LOW RANGE
Off-road position for driv-
ing off-road and fording
The gear ratio between the
engine and wheels is only
approximately one third of
that in the HIGH RANGE
road position. The drive
torque is correspondingly
higher as a result.
Do not use LOW RANGE:
R on slippery road surfa-
ces, e.g. in the case of
slush
R on snow or ice-covered
roads
R if you have snow chains
on your vehicle G
Risk of accident
Always wait for the gear change process from
HIGH RANGE to LOW RANGE – and from LOW
RANGE to HIGH RANGE – to complete. Do not
turn off the engine while changing gear and 114

board computer refer to those measured at
sea level. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge
are higher than those shown by the on-
board computer. In this case, do not reduce
the tyre pressures.
i After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the dis-
play message Tyre pressure monitor
active is shown instead of the tyre pres-
sure display. The tyre pressures are already
being monitored.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the speci-
fied values for monitoring.
In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
i You will find the menu overview on
(Y page 99).
If you wish to define the new reference values
manually:
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (Y page 180).
X Make sure that the key is in position 2in
the ignition lock.
X Press the &or* button to select the
Tyre pressure function or wait until the
following message appears: X
Press the reset button on the instrument
cluster (Y page 25).
The multi-function display shows the mes-
sage:
Restart tyre pressure monitor?
Yes Cancel
X Press the Wbutton.
The multi-function display shows the mes-
sage:
Tyre pressure monitor restarted
The tyre pressure monitor has stored the
pressure of the tyres as a new reference
value.
Cancelling the restart X
Press the Xbutton.
Other messages in the multi-function
display If in multi-function display the following mes-
sage appears:
Please correct tyre pressures
X
Check the tyre pressure on all four wheels
and correct it if necessary.
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions. Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After a wheel is changed, have the tightening
torque checked at a specialist workshop that
has the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use a 184

Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 150 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rear wheels you can interchange the wheels
every 5,000 km to 10,000 km depending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*.
! On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
i Vehicles with a tyre pressure monitor*
If the positions of the wheels on the vehicle
are changed, the tyre pressure may be tem-
porarily displayed in the wrong position.
This is rectified after a few minutes of driv-
ing; the tyre pressures are then displayed
in the correct positions. Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 184). Winter tyres
At temperatures below +7 ˚C always use all-
weather tyres or winter tyres and always use
winter tyres in winter road conditions. Only
winter tyres displaying the isnowflake
symbol in addition to the M+S marking pro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and
ESP ®
driving systems to function optimally in
winter, as these tyres have been designed
specifically for driving in snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of your vehicle and
cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent Speedtronic 27
to the maxi-
27 Only available for certain countries. Winter driving

R
Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance.
R Select a shift range appropriate to the gra-
dient.
R Before tackling steep downhill gradients,
select shift range 1.
i The vehicle will not roll backwards when
stopping on an uphill gradient if:
R the automatic transmission is in position
D.
R you have selected the LOW RANGE off-
road gear.
Depress the brake pedal when stopping on
steep uphill gradients. Hill start assist will
aid you when you pull away again
(Y page 90).
Maximum gradient-climbing capability On good road surfaces and with the LOW
RANGE off-road gear selected, the full gradi-
ent-climbing capability is available.
i
If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognises this and brakes the
wheels accordingly. The rear wheel torque
is increased and it is easier to pull away.
Brow of hill When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle’s own impetus to
travel over the brow.
This style of driving prevents: R
the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from travelling too quickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip
and overturn.
R Before tackling steep downhill gradients,
select shift range 1.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R Check that the brakes are working normally
after a long downhill stretch.
i Off-road ABS is activated when the
LOW RANGE off-road gear is selected.
At speeds below 30 km/h, the front wheels
lock cyclically during braking. The digging-
in effect achieved in the process reduces
the stopping distance when driving off-
road. The steerability of the vehicle is con-
siderably reduced when the wheels lock. Driving over obstacles
Observe the following rules when driving over
tree stumps, large stones and other obsta-
cles:
R Select the LOW RANGE off-road gear
(Y page 114).
R Avoid high engine speeds.
R Select shift range 1. Off-road driving

In the event of damage to the transfer
case Have the propeller shafts between the axles
and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the front axle
Have the propeller shaft between the rear
axle and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the rear axle Have the propeller shaft between the front
axle and the transfer case removed.
Have the vehicle towed with the rear axle
raised.
! New bolts must always be used when the
propeller shafts are refitted. The specified
tightening torques must be observed.
i Consult a Mercedes-Benz Service Centre.
In the event of damage to the electrical
system If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to neutral,
you must supply power to the vehicle’s elec-
trical system in the same way as jump-start-
ing (Y page 276).
Have the vehicle transported on a transporter
or trailer. Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
required fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. A circuit overload could other-
wise cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R dashboard fuse box on the front-passenger
side
R fuse box in the engine compartment on the
right-hand side of the vehicle
R fuse box in the luggage compartment on
the right-hand side of the vehicle
Fuse allocation chart The fuse allocation chart is located with the
vehicle tool kit (Y
