Charging the battery
The vehicle batt
ery should be charged by a
specialised workshop only, as batteries using
special technology have been installed and
they must be charged in a controlled environ-
ment

. SEAT recommends taking your
car in for technical service
.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features. If the battery must be re-
placed, consult a technical service for infor-
mation on electromagnetic compatibility, the
size and maintenance, performance and
safety requirements of the new battery in
your vehicle before you purchase one. SEAT
recommends you have the battery replaced
by a technical service.
Use only maintenance-free genuine batteries
conforming to TL 825 06 and VW 7 50 73
Standards. These standards must be dated
April 2008 or later.
Start-Stop systems (
›››
page 259) are equip-
ped with a special battery. Therefore, it must
only be replaced with a battery of the same
specifications.
Disconnecting the vehicle's battery
If you must disconnect the battery from the
el
ectrical system, please note the following:
●
Switch off the ignition and all electrical
equipment.
●
The vehicle must be unlocked before dis-
connecting the battery, otherwise the alarm

Diff

ent contr
ol lamps may light up after
connecting the battery and switching the ig-
nition on. They will be turned off after a short
trip at a speed of between 15-20 km/h
(10-12 mph). If the warning indicators remain
lit, please visit a specialised workshop to
have the vehicle checked.
If the battery has been disconnected for a
long time, it is possible that the next service
date is not displayed or calculated correctly

page 104. Respect the maximum service
intervals permitted

Vehicles with Keyless Access
(
›››
page 119): if, after connecting the battery,
the ignition cannot be switched on, lock and
unlock the vehicle from outside. Then try to
switch on the ignition again. If the ignition
does not work, seek professional assistance.
Automatically disconnecting devices
The intelligent vehicle electrical system auto-
matically implements a range of measures to
prevent the battery from discharging when
high demands are made on it:
●
the idling speed is increased so that the al-
ternator provides more electricity.
●
where necessary, the power of the most
powerful devices is reduced or even com-
pletely disconnected.
●
On starting the engine, the power supply
from the 12-volt power sockets and the ciga-
rette lighter may be interrupted for a short
time.
The on-board management program cannot
always prevent the battery from running flat.
For example, if the ignition is left on for a long
period with the engine off or if the side lights
or parking lights are left on while the vehicle is
stationary.
Why does the battery run flat?
●
When stationary for a long time without
starting the engine, particularly if the ignition
is switched on.
