Tow-starting means starting the engine of
the vehicle while another pulls it.
Towing means one vehicle pulling another
that is not roadworthy.
If the vehicle comes with the Keyless Access
system, towing is only allowed with the igni-
tion on!
The vehicle battery drains if the vehicle is
towed with the engine switched off and the
ignition connected. Depending on the battery
charge status, the drop in voltage may be so
large, even after just a few minutes, that no
electrical device in the vehicle may work e.g.
the hazard warning lights. In vehicles with the Keyless Access system, the steering
wheel cou

ld lock up. WARNING
If the vehicle has no electrical power, the
brak e light

s, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. WARNING
The risk of accidents is high when tow-start-
ing, f or e

xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.88

Opening and closing
Note
● Never l e
ave any valuable items in the vehi-
cle unattended. Even a locked vehicle is not a
safe.
● If the diode on the driver door sill lights up
for about 30 sec
onds when the vehicle is
locked, the central locking system or anti-
theft alarm* is not working properly. You
should have the fault repaired at a SEAT Offi-
cial Service or specialised workshop.
● The vehicle interior monitoring of the anti-
theft a
larm* system will only function as in-
tended if the windows and the sunroof* are
closed. Car key

Checking and refilling levels
CAUTION
● Do not mi x
cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
vis
ibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery

cause an e
xplosion! Replace a damaged bat-
tery immediately. CAUTION
● Never di s

connect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components. Charging the battery
Terminals for charging the battery are fitted
in the en
gine comp

artment. –
Note the warnin
gs ››› in Important safety
w arnin
g
s for handling a vehicle battery on
page 270 and ››› .
– Switch off all electrical devices. Remove the
ignition k ey
.
– R

aise the bonnet ›››
page 263.
– Open the battery cover.
– Connect the charger clamps as described
to the po

sitive pole of the battery (+) and
exclusively to an earth on the bodywork
(–).
– Only use a charger which is compatible for
use with 12

V nominal voltage batteries.
The charge must not exceed a voltage of 15
V.
– Now connect the battery charger to the
power soc

ket and switch on.
– After charging the battery: switch off the
batter

y charger and disconnect the power
socket cable.
– Finally disconnect the charger cables from
the batter

y.
– Replace the battery cover correctly.

page 263.
Important: Before you charge the battery
make sure you read the manufacturer's in-
structions for using the battery charger. WARNING
Never charge a battery that has frozen: re-
pl ac

e battery! Failure to do so may lead to an
explosion. Note
Use only the terminals in the engine compart-
ment t o c

harge the battery. Replacing the battery
The new battery should have the same speci-
fic
ation
s

(amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy ›››
page 255.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.
