2013 Seat Leon Sportstourer brake fluid

260Checking and refilling levels
WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicle's functions are “lost” ( ⇒ table
on page 260). These functions will require resetting after the battery is re-
connected.
Deactivate the anti-theft alarm* before you disconnect the battery Other-
wise the alarm will be triggered.

warning lamp goes out again.
If the vehicle is not used for long periods
The vehicle has a system for monitoring the current consumption when the
engine is left unused for long periods of time ⇒ page 226. Some functions,
such as the interior lights, or the remote door opening, may be temporarily
disabled to prevent the battery from running flat. These functions will come
back on as soon as the ignition is switched on and the engine started.
Winter conditions
During the winter, the starting power may be reduced, and if necessary, the
battery should be charged ⇒
