Battery
Important safety notes
Work on the battery, e.g. removing or installing,
requires specialist knowledge and the use of
special tools. Therefore, always have work on the battery carried out at a qualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
Further information can be found under "ABS"
(
Ypage 64) and under "ESP®" (Ypage 65).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The flammable gas mix is produced when the
battery is charged or when the vehicle is jump-
started.
Always make sure that neither you nor the bat-
tery are electro statically charged. Electrostatic
charging results, for example, from:
Rwearing synthetic clothing
Rfriction between clothing and the seat
Rdragging or pushing the battery across carpet
flooring or any other synthetic materials
Rrubbing the battery with cloths or towels.

Maintenance and care

Maximum tire pressures
:Maximum permitted tire pressure (example)
Never exceed the maximum permissible tire
inflation pressure. When adjusting the tire pres-
sures always observe the recommended tire
pressure for your vehicle (
Ypage 280).
iThe actual values for tires are specific to
each vehicle and may deviate from the values
in the illustration.
Tire valve (snap-in valve)
Important safety notes
GWARNING
Tire valve that are not approved for your vehi-
cle by the distributor named on the inside
cover page may result in a loss of tire pres-
sure. This may affect road safety. There is a
risk of an accident.
Only use tire valve that are approved for your
vehicle by the distributor named on the inside
cover page. Always make sure you have the
correct tire valve type for the tires on your
vehicle.
!Do not screw additional weights (check
valves, etc.) onto the tire valves. The elec-
tronic components could thus be damaged.
iFor safety reasons, Mercedes-Benz recom-
mends that you only use tire valves that have been tested for use on your vehicle.
Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceed as follows:
XRemove the valve cap of the tire you wish to
check.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with the
recommended value on the loading informa-
tion table or the tire pressure table
(
Ypage 280).
XIf the tire pressure is too low, increase it to the
recommended value.
XIf the tire pressure is too high, release air by
pressing down the metal pin in the valve. Use
the tip of a pen, for example. Then, check the
tire pressure again using the tire pressure
gauge.
XScrew the valve cap onto the valve.
XRepeat the steps for the other tires.
Tire pressure monitor
General notes
In vehicles with a tire pressure monitor system,
the vehicle's wheels have sensors installed
which monitor the tire pressure in all four tires.
The tire pressure monitor warns you if the pres- sure drops in one or more of the tires. The tire
pressure monitor only functions if the corre-
sponding sensors are installed on all wheels.
Tire pressure display (only on vehicles with steer-
ing wheel buttons)
On vehicles with steering wheel buttons, the
current pressure of the individual tires can be
shown in the display using the Service
menu.

nificantly too low. The tire pressure monitor is
not malfunctioning.
RUSA only: if thehwarning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.
The display also shows a message:

USA only: if the tire pressure monitor is mal-
functioning, it may be more than ten minutes
before the malfunction is shown. The htire
pressure warning lamp flashes for 60 seconds
and then remains lit. When the malfunction has
been rectified, the htire pressure warning
lamp goes out after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a pressure gage are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere with the operati
on of the tire pres-
sure monitor.
Checking the tire pressure electroni-
cally on vehicles with steering wheel
buttons
You can only check the tire pressure electroni-
cally on vehicles with steering wheel buttons.

few minutes of driving; the tire pressures are
then displayed for the correct positions.
Restarting the tire pressure monitor
General notes
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp goes out. The monitor uses the
currently set tire pressures as the reference val-
ues for monitoring. In most cases, the tire pres-
sure monitor will automatically detect the new
reference values after you have changed the tire
pressures. However, you can also define refer-
ence values manually as described here. The tire
pressure monitor then monitors the new tire
pressure values.
