1) Do not use the rear assist system in the fol-
lowing cases:
– If there is a fault in the dynamic chassis control (DCC).
– If the image displayed is not very clear or reliable (low
visibility or dirty lens).
– If the space behind the vehicle cannot be clearly or
completely recognised.
1) Do not use the rear assist system in the fol-
lowing cases:
– If the vehicle has been overloaded at the rear.
– If the driver is not familiar with the system.
– If the rear lid is open.
– If the position and installation angle of the camera
have been changed, e.g. in a rear-end collision. Have a
specialised workshop check the system.
2) Optical illusions of the camera (examples)
The rear assist camera produces two-dimensional im-
ages. Any cracks in or objects protruding from the
ground or from other vehicles are more difficult to spot
or cannot be seen due to a lack of depth in the image
displayed.
Objects or other vehicles may seem to be closer or fur-
ther away than what they really are:
– On changing from a flat surface to a slope or gradient.
– On changing from a slope or gradient to a flat surface.
– If the vehicle has been overloaded at the rear.
– On approaching protruding objects. These objects
may be outside the angle of vision of the camera when
reversing.

Operation
●
Never c onnect
the trailer's electric system
to the electrical connections of the rear lights
or any other power sources. CAUTION
Do not leave the trailer connected to the vehi-
c le when p

arked; places on its support wheel
or its supports. For example, when changing
the load or a puncture, the vehicle will be
pushed up or down. The force acting on the
tow hitch and the trailer could damage the
vehicle or the trailer. Note
● In the event of

a fault in the vehicle or trail-
er electrical system or in the event of prob-
lems with the anti-theft alarm system, have
the system checked by a specialised work-
shop.
● If the trailer accessories use energy from
the power soc
ket when the engine is stop-
ped, the battery will be discharged.
● For technical reasons, trailers fitted with
rear LED light
s cannot be connected to the
anti-theft alarm system.
● If the vehicle battery is running low, the
electrica
l connection with the trailer is auto-
matically cut.
● With the engine running, the electrical
equipment on the trai
ler will be supplied with
power. Loading the trailer
Trailer weight / drawbar load
The trai
l

er weight is the load that the vehicle
can pull ››› . The drawbar load is the vertical
weight of

the tow hitch on the tow hitch ball
››› page 245.
The figures for trailer weights and drawbar
load weights given on the data plate of the
tow hitch are for values of this model only.
The correct figures for your specific vehicle,
which may be lower than these figures for the
tow hitch, are given in the vehicle documen-
tation. The instructions in the official vehicle
documents take precedence.
For the sake of road safety, SEAT recom-
mends using the maximum allowed drawbar
load. The handling of the combined vehicle
and trailer will be poor if the drawbar load is
too low.
The drawbar load increases the weight on the
rear axle, reducing the vehicle carrying ca-
pacity.
Gross combination weight
This figure refers to the combined weight of
the loaded vehicle and loaded trailer.
Loading the trailer
The combined vehicle and trailer must be
balanced. Use the maximum drawbar load authorised and do not overload the front or
the re
ar of

the trailer:
● Distribute loads in the trailer so that heavy
obj
ects are as near to the axle as possible or
above it.
● Correctly secure the trailer load.
Tyr
e pressure
Inflate the trailer tyres according to the man-
ufacturer's instructions.
Inflate the towing vehicles tyres to the maxi-
mum ››› page 287. WARNING
Exceeding the maximum authorised axle
loa d, dr

awbar load or the gross combination
weight of the towing vehicle and trailer could
cause a serious accident with severe conse-
quences.
● Never exceed the specifications.
● With the actual load on the front and rear
axle
s, the maximum axle load should never
be exceeded. The weight on the front and rear
should never exceed the gross vehicle
weight. WARNING
If the load moves, the stability and safety of
the v ehic

le and trailer combination will be se-
riously affected and this could result in a seri-
ous accident. 242

Checking and refilling levels
●
Top up w ith AdBlue at
the latest 1,000 km
or 600 miles before it runs out.
● Do not allow the AdBlue to run too low. WARNING
AdBlue is an irritant, corrosive liquid that can
c au se injurie

s if it touches the skin, eyes or
respiratory organs.
● If AdBlue get in contact with eyes and skin,
rinse for at
least 15 minutes with plenty of
water and seek medical help.
● If the AdBlue is swallowed, wash your
mouth with pl
enty of water for at least 15 mi-
nutes. Do not try to provoke vomiting unless
recommended by a Doctor. Seek medical ad-
vice immediately. CAUTION
AdBlue damages surfaces such as painted ve-
hicl e p

arts, plastic, items of clothing and car-
pets. Spilt AdBlue should be removed as
quickly as possible using a damp cloth and

 page 40
Preparations ● Park the vehicle on flat ground so that the
engine oil
reading is correct. ●
Stop the engine and w
ait a few minutes for
the oil to drain back into the sump. When the
engine has cooled down, immediately check
the oil level and top up if necessary.
● Open the bonnet  ›››
page 271.
● The engine oil filler neck can be recognised
by the symbo
l  on the cap ››› Fig. 243 and
the dipstick by its coloured handle.
Checking the engine oil level
● Pull out the dipstick and wipe it on a clean
cloth.
● Rep

lace the dipstick, pushing it in as far as
it wi
ll go. If the dipstick has a mark, when you
reintroduce it this mark should slot into the
corresponding groove located on the upper
end of the tube.
● Remove the oil dipstick again and check
the engine oil
level.
● After reading the oil level, replace the dip-
stick
in the tube completely.
Adding oil after checking the level
Only add engine oil in small quantities and in
steps:
● Unscrew the cap from engine oil filler neck
on the cylinder head ›

›› Fig. 243. If you are
not sure where the cap is, request help from
a specialist. ●
Only r
efill using approved SEAT engine oil
in small quantities (no more than 0.5 l)
››› page 275.
● To avoid adding too much oil, each time
you ad
d a quantity, wait until the oil has flow-
ed into the crankcase so that it can be meas-
ured with the dipstick.
● Check the oil level before adding any more
oil. Do not
top up with too much engine oil
››› .
● When the oil level is at least in the
› ›
›

Fig. 242 B zone, insert the dipstick into
the t ube f
u
lly to avoid engine oil escaping
when the engine is running.
● After topping up the oil, ensure that the
cap is
screwed on to the filler neck correctly. WARNING
Oil could catch fire if it comes into contact
with hot en

gine components. This could lead
to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the
engine oil
filler cap is correctly tightened.
This will avoid engine oil spilling onto hot en-
gine parts when the engine is running. CAUTION
● If the en gine oi

l level is above the area
››› Fig. 242 A do not start the engine. Seek
spec i
alist assistance. Otherwise catalytic
converter and engine damage may occur. 276

Advice

aced damaged or frozen batteries as
soon as possible. A flat battery can also
freeze at temperatures close to 0°C (+32°F).
● For vehicles with the battery in the luggage
compar
tment: Check that the battery gas
ventilation hose is securely attached. CAUTION
● Nev er 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.
● Do not expose the battery to direct sunlight
over a lon
g period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the car is left standing for long periods,
protect
the battery from extreme cold temper-
ature so that it does not “freeze up” and be-
come damaged. Warning lamp

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

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 102. Respect the maximum service
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

WARNING
Incorrectly securing the battery or using the
wron g b
attery can cause short-circuits, fire
and serious injuries.
● Always use only maintenance free batteries
that do not
run flat alone and whose proper-
ties, specifications and size correspond to
the standard battery. The specifications are
indicated on the battery case. WARNING
A highly explosive mixture of gases is re-
le a

sed when the battery is under charge.
● The batteries should be charged in a well-
ventil
ated room only.
● Never charge a frozen or recently thawed
batter
y. A flat battery can also freeze at tem-
peratures close to 0°C (+32°F).
● Always replace a battery which has frozen.
● Battery cables not correctly connected may
cause a shor
t circuit. Reconnect first the posi-
tive cable and then the negative cable. 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.
● Never plug accessories that supply current,
such a
s solar panels or a battery charger, to
the 12-volt power sockets or the cigarette lighter. This could damage the vehicle's elec-
trica
l

system. For the sake of the environment
● Di spo

se of the battery in an environment-
friendly manner. Batteries contain toxic sub-
stances such as sulphuric acid and lead.
● Battery acid can contaminate the environ-
ment. If it
has leaked use adequate care col-
lecting it (gloves and protective glasses), and
dispose of it correctly. Wheels and tyres
T y
r

es
Introduction The SEAT Alhambra is equipped as standard
with anti-p
u

ncture technology tyres (Conti-
Seal). In the event of a puncture or air leak of
up to 5 mm, the tyre seals the hole with a
protective layer inside the tread.
The inclusion of this technology means that
there is no type of spare wheel included in
the vehicle's equipment.
SEAT recommend that all work on tyres and
wheels is carried out by a specialised work-
shop. These workshops have the necessary
special tools and replacement parts, trained
personnel and facilities for disposing of the
old tyres while respecting the environment.
SEAT recommends taking your car in for tech-
nical service. WARNING
The vehicle cannot be totally controlled or
brak ed if

the tyres (new or used) are worn or
damaged.
● Incorrect use of wheels and tyres could
make driv
ing more dangerous and result in
serious accidents and damage. » 287

only be replaced at a specialised workshop.
SEAT recommends visiting a technical service
››› .
WARNING
The use of worn or damaged wheel rims could
mak e driv

ing more dangerous and result in
serious accidents and damage.
● Only wheel rims which have been approved
for use w
ith your vehicle should be used.
● Inspect wheel rims regularly for damage
and repl
ace as required. WARNING
If the bolted joints of wheel rims with bolted
ring trims ar

e not correctly tightened or loos-
ened, this could result in serious accident.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims.
● Any work relating to wheel rims with bolted
rims shoul
d be carried out at specialised
workshop. SEAT recommends taking your car
in for technical service. Note
A SEAT Service Centre should be consulted to
find out whether wheel s

or tyres of different
sizes to those originally fitted by SEAT can be
fitted, and to find out about the combinations
allowed between the front axle (axle 1) and
the rear axle (axle 2). Replacement of wheel rims and new
ty
r
e

s New tyres
● When tyres are new, drive with extreme
c aution f
or the fir

st 500 km (310 miles), as
all tyres need to be run in. Tyres which have
not been run in do not have such good grip
or ››› braking capacity
››
›
.
● All four wheels must be fitted with radial
ty r
e

s of the same type, size (rolling circumfer-
ence) and the same tread pattern. ●
The trea
d depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Replacing tyres
● Where possible, always replace both
wheels on an ax
le (both wheels on the front
axle or both wheels on the rear axle) ››› .
● Old tyres should only be replaced by SEAT
ap pr
o

ved tyres for the vehicle in question,
and in accordance with the maximum permit-
ted size, diameter, load and speed capacity.
● If replacing tyres, make sure the new ones
have an emer
gency ride system (Conti-
Seal/Run flat). Otherwise, we recommend
carrying a tyre mobility system.
● Never use tyres which are larger than SEAT
appro
ved tyres. If the tyres are too big, they
may knock or rub against the chassis or other
components, resulting in damage. WARNING
New tyres do not give maximum grip and will
not h av

e reached their maximum braking ca-
pacity to start with, and therefore need run-
ning in.
● To prevent accidents and major damage,
extreme c
aution should be taken for the first
500 km (310 miles). 290

Wheels and tyres
WARNING
There should be adequate space between the
tyr e
s and the vehicle in accordance with the
vehicle design. If this is not the case, the
tyres may rub against parts of the running
gear, chassis or brake lines, leading to faults
in the brake system or to tread detachment,
and the risk of burst tyres.
● The true tyre dimension should not be
great
er than the dimensions of tyres manu-
factured and approved by SEAT and should
not rub against parts of the vehicle. Note
● Although ty r

es may be shown as being the
same size, the true dimensions of different
types of tyre may vary with respect to the
nominal size, or tread patterns may be differ-
ent.
● If you use tyres that are approved by SEAT,
you can be s
ure that the true tyre dimensions
will be correct for your vehicle. For other tyre
models, the tyre vendor should provide the
manufacturer's certificate with the tyre, indi-
cating that this type of tyre is suitable for
your vehicle. This certificate should always
be carried with the vehicle. Tyre pressure

or

y is shown on a label and is valid
for summer and winter tyres. This label
››› Fig. 252 is either on the driver door strut or
inside the fuel tank flap.
Under-inflation or over-inflation will reduce
the life of the tyres considerably and also im-
pair the car's handling ››› . It is essential to
m aint
ain the c

orrect tyre pressures, especial-
ly if driving at high speeds. Incorrect tyre
pressure causes premature wear and could
cause tyre blow-out. The pressure should therefore be checked at
lea

st once a month and before starting a
journey.
As a general rule, the pressures given are for
cold tyres. When the tyres are hot, the pres-
sures are greater.
Never deflate a hot tyre in order to obtain the
required pressure. This could result in very
low tyre pressures which may lead to sudden
blow-outs.
Checking tyre pressures
Tyre pressures should only be checked when
the vehicle has not been driven for more than
a few kilometres (miles) at low speeds in the
past three hours.
● The tyre pressures should be checked regu-
larly, and on
ly when the tyres are cold. Al-
ways check all the tyres. Tyre pressures
should be checked more often in colder re-
gions, and only when the vehicle has not
been driven recently. Always use a correctly-
operating tyre gauge.
● Adjust tyre pressures to the loads carried in
the vehic
le.
● After checking the pressure, always replace
the valv
e caps, and where applicable, ob-
serve the instructions given for adjusting the
tyre control system ››› page 234. »

● If the tyre pressure is too low, they could
overhe
at, resulting in tread detachment or
even burst tyres.
● When driving at high speeds and/or fully
loaded, the ty
re could suddenly overheat,
burst or be subject to tread detachment, with
the resultant loss of control of the vehicle.
● Tyre pressures which are too high or too
low reduc
e the service life of the tyre, affect-
ing the vehicle's performance.
● Tyre pressures should be checked regularly,
at le
ast once a month and before long jour-

● Tak e c

are not to tilt the manometer when
placing it on the valve. Otherwise, the valve
may be damaged.
● If tyre valves are not protected by caps, or if
the caps
are not screwed on correctly, they
may become damaged. Check that the caps
are identical to the standard caps and have
been correctly tightened. For the sake of the environment
Under-inflated tyres will increase fuel con-

Tyre tread: tread wear indicators Tread depth
C
er
t

ain driving conditions require a deeper
tread, as well as needing the tread to be ap-
proximately the same on the front and rear
tyres. This is particularly important when
driving in winter, in cold temperatures and on
wet roads ››› .The minimum tread depth required by law in
the m
aj
ority

of cases is 1.6 mm (1/16 of an
inch), measured in the tread grooves next to
the tread wear indicators. Observe legal re-
quirements in each country.
Winter tyres lose much of their performance
when their tread has worn to 4 mm
(5/32 inch).
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Wear indicators on the tyre
The original tyres on your vehicle have
1.6 mm (1/16 inch) high ››› Fig. 253 tread
wear indicators running across the tread. A
number of these indicators are equally
spaced around the tyre tread. Certain marks
on the tyre walls (e.g. the letters “TWI” or
other symbols) indicate the position of the
wear indicators.
Tread wear indicators indicate if a tyre is
worn. They must always be replaced before
the tyre tread has worn to the level of the in-
dicator. WARNING
Driving with worn tyres is dangerous, and
ma y

lead to loss of control of the vehicle with
serious consequences. 292
