2015 Seat Leon 5D ABS

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

The battery is located in the engine compart-
ment and is almost maintenance-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 dis- connected, some of the vehicle's functions
are “los

t” (››› table on page 253). These
functions will require resetting after the bat-
tery is reconnected.
Deactivate the anti-theft alarm* before you
disconnect the battery Otherwise the alarm
will be triggered.

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

Tyre monitoring indicator Fig. 240
Instrument panel: warning of loss of
ty r
e pr
essure. The tyre monitor indicator compares wheel
r
ev
o

lutions and, with this information, the
tread of each wheel using the ABS sensors. If
the rolling circumference of one or more
wheels has changed, the tyre monitoring in-
dicator will indicate this on the instrument
panel through a warning lamp and a warning
to the driver ››› Fig. 240. When only one spe-
cific tyre is affected, its position within the
vehicle will be indicated.
 Loss of pressure: Check left
tyre pressure!
Wheel tread change
The wheel tread changes when: ●
Tyr
e pressure is manually changed
● Tyre pressure is insufficient
● Tyre structure is damaged
● The vehicle is unbalanced because of a
load
● The wheel

s on an axle are subject to a
heavier lo
ad (e.g. with a heavy load).
● The vehicle is fitted with snow chains
● The temporary spare wheel is fitted
● The wheel on one axle is changed
There ma
y be a delay in the reaction of the
tyre  monitoring indicator or it may not in-
dicate anything under certain circumstances
(e.g. sporty driving, snow-covered or un-
paved roads, or when driving with snow
chains). Calibrating the tyre monitoring indica-
