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 209) 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
electrical system, please note the following:
● Switch off the ignition and all electrical
equipment. ●
The vehic le must be unlocked before dis-
connecting the battery, otherwise the alarm
will be triggered.
● First disconnect the negative cable and

control 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

intervals permitted ››› Booklet Maintenance

Vehicles with Keyless Access (››› page 117):
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 intellig
ent 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-
ternat
or provides more electricity.
● where necessary, the power of the most
power
ful devices is reduced or even com-
pletely disconnected.
● On starting the engine, the power supply
from the 12-v
olt 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
star
ting the engine, particularly if the ignition
is switched on.
● Use of electrical devices with the engine
switc
hed off.
● If the auxiliary heater is running
