Checking brake fluid level
The brake fluid Level must be between the MIN
and MAX marks on the reservoir ¢ page 222,
Fig. 211.
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
¢page 11.
In right-hand drive vehicles the brake fluid reser
voir is on the other side of the engine compart
ment.

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.

the sealed original container in a safe place
out of the reach of children.
- Heavy use of the brakes may cause a vapour
Lock if the brake fluid is left in the system
for too Long. This would seriously affect the
efficiency of the brakes and the safety of the
car -risk of accident!

CAUTION
Brake fluid must not be allowed to come into
contact with the vehicle's body, otherwise it
will attack the paintwork.
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
¢ .&.. in General notes on airbag system on
page 209.
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 vehi cle 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 ¢ page 106. Certain convenience fea
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
