Some mobile devices connect to Wi-
Fi hotspots automatically and use
mobile data capacity in thebackground, even if they are not in
use. This includes automatic
updates, downloads, as well as
programme or app synchronisation
traffic. The data volume purchased

that they roll in the direction of travel.
The rolling direction is indicated by a
symbol (e.g. an arrow) on the
sidewall.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
The vehicle battery is located in the
load compartment under a cover.
There are connecting points for jump
starting in the engine compartment.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.
Do not start with quick charger.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster vehicle battery with the same voltage (12 Volt).
Its capacity (Ah) must not be
much less than that of the
discharged vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
