Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and
has special safety features. If the battery requires replacement, consult a
Technical Service for information 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.
Vehicles fitted with the Start-Stop system are equipped with a special bat-
tery. Therefore, this battery must only be replaced by another with the same
specifications.
Disconnecting the vehicle's battery
If you have to disconnect the battery from the electrical system, please note
the following:
● Switch off the ignition and all electrical devices.
● The vehicle must be unlocked before disconnecting the battery, other-
wise the alarm will be triggered.
● First disconnect the negative cable and then the positive ⇒
Connecting the vehicle's battery
● Before reconnecting the battery, switch off the engine, the ignition and
electrical devices.
● First reconnect the positive cable and then the negative ⇒
Different control lamps may light up after connecting the battery and switch-
ing the ignition 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 ⇒ p age 43. Respect
the maximum service intervals permitted ⇒ B ooklet Maintenance Pro-
gramme.
Automatic device disconnection
The intelligent vehicle electrical system automatically 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 alternator provides more elec-
tricity.
● Where necessary, the power of the most powerful devices is reduced or
even completely disconnected.
● On starting the engine, the power supply from the 12-volt socket and
the cigarette 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 the battery runs flat:
● When stationary for a long time without starting the engine, particularly
.
if the ignition is switched on.
● Use of electrical devices with the engine switched off.
WARNING
.
Incorrectly securing the battery or using the wrong battery can cause
short-circuits, fire and serious injuries.
● Always use only maintenance-free batteries, protected to prevent a
leak, and whose properties, specifications and size correspond to the
battery installed as standard.
