Important safety notes G
WARNING
When a load is transported on the roof, the
vehicle's centre of gravity rises and the han-
dling changes. If you exceed the maximum
roof load, the handling as well as steering and braking characteristics are severely affected.
There is a risk of an accident.
Always observe the maximum roof load and
adapt your driving style.
! Mercedes-Benz recommends that you
only use roof carriers that have been tested and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehi-
cle. Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Make sure that, depending on the vehicle's equipment, you can raise the sliding sun-
roof fully and open the boot lid or tailgate
fully when the roof carrier is fitted.
! To avoid damaging or scratching the cov-
ers, do not use metallic or hard objects to
open them.
The maximum roof load can be found in the
"Technical Data" section (Y page 407).
The maximum roof load can be found in the
"Technical data" section in the printed Own-
er's Manual.
An incorrectly secured roof carrier or roof
load may become detached from the vehicle.
You must therefore ensure that you observe
the roof carrier manufacturer's installation
instructions.
Attaching the roof carrier X
Open covers :carefully in the direction of
the arrow.

characteristics)
General notes With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres. The affected
tyre must not show any clearly visible dam-
age.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the
tyre wall. You will find this marking next to the
tyre size designation, the load-bearing capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning system or tyre pressure monitoring
system.
If the pressure loss warning message
appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 280).
R check the tyre for damage.
R if driving on, observe the following notes.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis- tance possible depends upon:
R speed
R road condition
R outside temperature
The driving distance possible in run-flat mode may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through a moderate style of driving. Flat tyre

Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump- starting.
Always make sure that neither you nor the
battery is electrostatically charged. Electro-
static charge is created, for example:
R by wearing synthetic fibre clothing
R due to friction between clothing and the
seat
R when you pull or push the battery across
carpet or other synthetic materials
R when you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
