and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.

In your vehicle, you will find a sticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.

Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the tyre pres-
sure table on the fuel filler flap for values.
X
To increase the tyre pressure: switch on
the tyre inflation compressor.
X
To reduce the tyre pressure: press pressure
release button
E
on the hose.

When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.
X
Screw the valve cap onto the tyre valve of the
sealed tyre.

Pull the tyre sealant bottle out of the tyre
inflation compressor.
The filler hose stays on the tyre sealant bottle.

12 V battery - important safety notes
PLUG-IN HYBRID vehicles are equipped with a
12 V battery and a high-voltage battery. The fol-
lowing notes refer to the 12 V battery. Notes on
the high-voltage battery can be obtained in the
"High-voltage battery – important safety notes"
section (
Y
page 394).
Work on the battery, e.g. removing or fitting,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop.
G
WARNING
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:
R
when braking
R
in the event of abrupt steering manoeuvres
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. Always
have work on the battery carried out at a
qualified specialist workshop.

Y
page 70) and

WARNING
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.
