Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.

workshops: (Y page 23). Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop. For an overview, see the instrument panel illus-
tration (Y page 27). Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster auto-
matically controls the brightness of the multi-
function display. In daylight, the displays in the
instrument cluster are not illuminated.
The lighting in the instrument cluster, in the dis- plays and the controls in the vehicle interior can
be adjusted using the brightness control knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(Y page 27).
X Turn the brightness control knob clockwise or
anti-clockwise.
If the light switch is set to the Ã,Tor
L position, the brightness is dependent
upon the brightness of the ambient light. READY indicator
When the drive system is started and the vehicle
is ready to drive, READY indicator :appears in
the multifunction display. This indicates that the vehicle is operational. Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the measured air temperature
and not the road surface temperature.
The outside temperature display is in the multi-
function display (Y page 175).
There is a short delay before a change in outside
temperature appears in the multifunction dis-
play. 172

G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a load:
R never exceed the maximum permissible gross
vehicle weight or the permissible axle loads
for the vehicle (including occupants).
R the luggage compartment is the preferred
place to carry objects.
R position heavy loads as far forwards as pos-
sible and as low down in the load compart-
ment as possible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place.
R always place the load behind unoccupied
seats if possible.
R use the lashing eyelets and the luggage nets
to transport loads and luggage. R
only use lashing eyelets and fastening com-
ponents that are suitable for the weight and
size of the load.
R hook in the safety net when loading.
R the maximum load capacity of the stowage
well under the luggage compartment floor is
25 kg.
R secure the load with sufficiently strong and
wear-resistant lashing material. pad sharp
edges for protection.
! Do not position the load on one part of the
folding luggage compartment floor only. The
maximum load capacity of the folding luggage compartment floor is 100 kg. Spread the
weight evenly to avoid damaging the luggage
compartment floor. Place a solid board under the load if necessary. Please note that the
load on the luggage compartment floor will be increased when the load is lashed down. Stowage areas
Stowage compartments
Important safety notes G
WARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction.
R Always stow objects so that they cannot be
thrown around in such situations.
R Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
R Close the lockable stowage spaces before
starting a journey.
R Stow and secure objects that are heavy,
hard, pointed, sharp-edged, fragile or too
large in the luggage compartment.
Observe the loading guidelines (Y page 224).224

Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 209).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
for the wrong positions for a short time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed for the correct
positions.
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 cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor will automatically detect the new refer-
ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.
X Use the table on the inside of the charge
socket 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 269).

Changing a wheel
Flat tyre
You can find information on what to do in the
event of a flat tyre in the "Breakdown assis-
tance" section (Y page 249). Information on
driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown assis-
tance" (Y page 250). 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 a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Changing a wheel" section (Y page 273).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear 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.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and reac-
tivate the tyre pressure monitor if necessary. Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk 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. Changing a wheel

must be positioned vertically, directly under
the jacking point of the vehicle.
! Position a suitable jack correctly on the
intended jacking points. If you fail to position the jack correctly, the vehicle may be dam-
aged.
The jacking points for the jack are recesses in
the lower door sill. They can only be seen from
underneath. There is one located behind each
of the front wheel arches and in front of the
rear wheel arches.
Position the jack in the jacking points so that
when viewed from the side, the jack is in the
vertical position.
! Position a suitable jack only on the jacking
points intended for this purpose.
Never position the jack on the high-voltage
battery. Do not jack up the vehicle on the
high-voltage battery. There is otherwise a risk of damaging the high-voltage battery.
Also observe the notes in the "Changing a
wheel" section.
Observe the following when raising the vehi- cle:
R to raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not permissible to use it to per- form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake and
positioning wheel chocks. Do not release the parking brake while the vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
R do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height. R
make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the drive system when the vehicle
is raised.
R do not open or close a door or the tailgate
while the vehicle is raised.
R make sure that no persons are present in the
vehicle when the vehicle is raised. X
Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts completely. Jacking points
The jacking points are located just behind the
front wheel arches and just in front of the rear
wheel arches (arrows). Changing a wheel
