WARNING
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If ad rive wheel spins due to insufficien tgrip:
R only depress the accelerator peda lasfar as
necessary when pulling away.
R accelerate less when driving.
R adapt yourd riving style to suitr oad and
traffic conditions.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+ Styres), wit hsnow
chain sifnecessary.
4MATIC ensures that all four wheels are per-
manentl ydriven .Together wit hESP®
,it
improves th etraction of your vehicl ewhen-
eve rad rive wheel spins due to insufficient
grip. 184

Important safet
ynotes
Work on the battery, e.g. removin gorinstal-
ling, requires specialist knowledge and the
use of special tools. Therefore, alway shave
work on the batter ycarried out at aqualified
specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can, for example, lead to ashort circuit and
damage your vehicle's electronic system. This
can disrupt driving safety systems such as
ABS (anti-lock brakin gsystem) or ESP ®
(Elec-
tronic Stabilit yProgram).
R If AB Smalfunctions, th ewheels can lock
during braking. This limits th esteerability
of th evehicl ewhen brakin gand th ebraking
distanc emay increase .There is arisk of
accident.
R If ESP ®
malfunctions, the vehicle will not be
stabilised if it starts to skid or awheel starts
to spin. There is arisk of accident.
You should therefore have all work involving
the battery carried out at aqualified specialist
workshop. G
WARNING
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.316

Tyre pressure monitor
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommende dcold tyre pres-
sure suitable for the operating situation
(Y page 331). Note that the correc ttyre pres-
sur efor the curren toperating situation must
first be taught-in to the tyre pressure monitor.
If there is asubstantial loss of pressure, the
warning threshold for the warning message is
aligned to the referencev alues taught-in.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure
(Y page 335). The current pressures are
saved as new referencev alues. This will
ensure that awarning message will only
appearift he tyre pressure drops significantly.
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 331).
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.Int he
event of asudden loss of pressure, bring the
vehicle to ahalt by braking carefully. Avoid
abrupt steering manoeuvres.
If at yre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you if the
pressure drops in one or more of the tyres.
The tyre pressure monitor only functions if
the corresponding sensors are fitted to all
wheels.
Information on tyre pressures is displayed in
the multifunction display. After afew minutes
of driving, the current tyre pressure of each
tyre is shown in the multifunction display.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at afilling station using apressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pressure values indicated by
apressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the tyre
pressures.
The operation of the tyre pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.
Checking tyrep ressureelectronically X
Make sure that the key is in position
2(Y page 141) in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The current tyre pressure for each wheel
will be displayed in the multifunction dis-
play.
If the vehicle was parked for longer than
20 minutes the Tyre pressures will be displayed after
afew minutes of driving message is shown.
After ateach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. If aclear allocation of
the tyre pressure values to the individual
wheels is not possible, the Tyre pressure monitor active message is shown instead
of the tyre pressure display. The tyre pres-
sures are already being monitored.
i If an emergency spare wheel is fitted, the
system may continue to show the tyre pres-
sure of the wheel that has been removed
for afew minutes. If this occurs, note that
the value displayed for the position where
the spare wheel is fitted is not the same as
the current tyre pressure of the emergency
spare wheel. 334

Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects
asignifi-
cant pressure loss on one or more tyres, a
warning message is show ninthe multifunc-
tion display. Awarning tone also sounds and
th et yrep ressure warning lamp light supin
th ei nstrumen tcluster.
Eac htyret hatisa ffected by asignificant loss
of pressure is highlighted in th epressure dis-
play.
X If the Please correc ttyrep ressure message appear
sinthemultifunction dis-
play, check th etyrep ressure on all four
wheels and correct it if necessary.
i If th ewheel positions on th evehicle are
interchanged, th etyrep ressure smay be
displayed for th ewrongpositions for a
short time. This is rectified after afew
minute sofdriving,and th etyrep ressures
are displayed for th ecorrec tpositions.
Restarting th etyrep ressure monitor When you restar
tthe 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 refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new referencev alues after you
have changed th etyrep ressure .However,
you can also define reference values man-
uallyasd escribed here. The tyre pressure
monitor then monitors the new tyre pressure
values.
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 331).
X Make sure that the key is in position 2in
the ignition lock. X
Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The multifunction display shows the cur-
rent tyre pressure for each tyre or the
Tyre pressures will be displayed after a few minutes of driving mes-
sage.
X Press the :button.
The multifunction display shows the Use current pressure values as new ref‐
erence values message.
If you wish to confirm the restart:
X Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have driven for
afew minutes, the
system checksw hether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Radio typea pproval for the tyrep res-
sure monitor In certain countries,
aradio type approval for
the tyre pressure monitor may be required.
