Checking brake fluid level
The brake fluid level must be between the MIN
and MAX marks on the reservoir c:>
Fig. 215.
If the level goes down noticeably in a short time,
or drops below the MIN mark, there may be a
leak in the brake system. Obtain professional as­
sistance. The brake fluid level is also monitored
via a warning lamp on the infotainment display

In right-hand drive vehicles the brake fluid reser­
voir is on the other side of the engine compart­
ment.
Changing brake fluid
Your vehicle's Service Schedule will tell you the
regular intervals at which the brake fluid is due
for renewal. We recommend that you have the
brake fluid changed by a qualified workshop dur­
ing a service.

Battery
General notes
All work on batteries requires specialist knowl­
edge.
The battery is virtually maintenance-free. It is
checked as part of the Inspection Service.
When an airbag is triggered, the battery will, un­
der certain circumstances, be disconnected from
the on-board power supply for safety reasons

Disconnecting the battery
The battery should always be left connected. If
the battery is disconnected, some of the vehicle's
functions will become inoperative (e.g. electric
windows). These functions will require resetting
after the battery is reconnected. For this reason,
the battery should only be disconnected from the
vehicle's electrical system when absolutely nec­
essary.
If the vehicle is not used for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are
using. This limits the amount of power consumed
and helps to ensure reliable starting even after a
long period

tures, such as interior lighting or electric seat ad­
justment, may not be available. These functions
will be restored when you switch on the ignition
and start the engine. Even though some systems
are deactivated automatically, certain electrical
equipment continues to draw current even when
the ignition is off. If the vehicle is left standing
for several months, this can result in total bat-
tery discharge. If the battery is allowed to dis­
charge completely, an internal chemical reaction
