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 164).

the ignition lock.
The standard display appears in the multi-
function display (Y page 101).

tion steering wheel.
The tyre pressure values stored at the last
restart will continue to be monitored. Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 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.
Interchange the wheels every 5,000 km to
10,000 km depending on the degree of tyre
wear, provided that the vehicle has the same
size front and rear tyres. 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
reactivate the tyre pressure monitor* if nec-
essary. Operation

Service
181Service
ASSYST service interval display
The ASSYST service display informs you when
the next service is due. Whenever a service is
due, this is shown in the multi-function dis-
play:
Service A in ..days
Service A in .. km
Service A due now The symbol and the letter indicate which type
of service is due:
9
Minor service A
½ Major service B
The ASSYST service display does not record
any periods of time during which the battery is disconnected. In order to maintain the
time-dependent service schedule, you should
call up the service due date and make a note
of it before disconnecting the battery. The
alternative is to subtract the battery discon-
nection periods from the service date shown
on the display.
Fading out the service message
The service message disappears automati-
cally after a few seconds. You can also fade
out the service message yourself.

Reset button
X Press reset button 1. Missing the service due date One of the following messages appears in the
multi-function display:
Service A overdue by .. days
Service A overdue by .. km
You will also hear a warning tone.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, resets the
ASSYST service display after the service work
has been carried out.
i If you fail to have the service performed
by the specified date, you may be violating
applicable laws. Your warranty may be inva-
lidated and goodwill settlements may be
refused.

ing wheel. Operation

Jump-starting
251
X
Connect positive terminal clamp 1and
secure the cover.
X Connect negative terminal clamp 3.
X Connect breather hose 4. Make sure that
a cell cap is fitted between battery 2and
breather hose 4.
i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:2
R set the time (Y page 106)
R reset the head restraints on the front
seats (Y page 61)
R reset the side windows ( Ypage 85) Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R Jump-starting may only be performed when
the engine and catalytic converter are cold.
R Do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R Jump-starting may only be performed with
batteries that have the same nominal volt-
age.
R Only use jump leads which are protected
against polarity reversal and which have a
sufficient cross-section and insulated ter-
minal clamps.
i Jump leads which are protected against
polarity reversal and further information
about jump-starting can be obtained from
any Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts. Only use the jump-starting pro-
cedure for the battery in the engine com-
partment. Do not use a rapid-charging device to start
the engine. G
Risk of injury
There is a risk of acid burns when jump-
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. G
Risk of explosion
Gases escaping from the battery during
jump-starting may cause minor explosions.
Avoid creating sparks. Keep naked flames
away from the battery, and do not smoke.
Comply with safety precautions and take
protective measures when handling batter-
ies. You will find these under "Battery" in
the index.
X Make sure that the two vehicles do not
touch.
X Apply the parking brake.
X Move the selector lever to P.
X Switch off all electrical consumers. Practical advice
