Stow all objects securely in the vehicl esothat
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribe dinorder to ensure that there is always
sufficient room for the pedals. Do not use

rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from aqualified
specialist workshop.
Leather is anatural product.
It has natural surface properties, e.g.:
R unevenness in structure
R marks caused by growth and injury
R subtle colour differences
These are characteristics of leather and not
material faults.

ressure loss warning system
General notes While the vehicle is in motion
,the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in atyre. If the speed of rotation of
aw heel changes as aresult of aloss of pressure,
ac orresponding warning message will appear in
the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active

Restart with OK Restart with OK message which appears in
the Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 358).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 356).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
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 .Inthe event of
as udden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you are towing avery heavy or large trailer. R
you are driving with aheavy load (in the vehi-
cle or on the roof).

the respective operating conditions. The rec-
ommended tyre pressures can be found in the

Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all

You can find information on what to do in the
event of aflat tyre in the "Breakdown assis-
tance" section (Y page 337). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown assis-
tance" (Y page 337).
Vehicles with an emergency spare wheel: in
the event of aflat tyre, the emergency spare
wheel is fitted according to the description
under "Fitting awheel" (Y page 362). Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is arisk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions. !
On vehicles fitted with
atyre pressure mon-
itor, electronic componentsa re located in the
wheel.
Tyre-fitting tools should not be applied in the area of the valve, as this could damage the
electronic components.
Only have tyres changed at aqualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructionsa nd safety notes in the
"Fitting awheel" section (Y page 362).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before aclear wear pat-
tern has formed on the tyres. Front tyres typi-
cally 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 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Cleant he contact surfaces of the wheel and the
brake disc thoroughly every time awheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system (Y page 358) or the tyre pressure
monitor (Y page 360). Direction of rotation
Tyres with aspecified direction of rotation have
additional benefits, e.g. if there is arisk of aqua-
planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in acool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Changing
