information about wheel bolts
The wheel rims and bolts have been de-
signed to be fitted to factory options. If differ-
ent rims are fitted, the correct wheel bolts
with the right length and correctly shaped
bolt heads must be used. This ensures that
wheels are fitted securely and that the brake
system functions correctly.
In some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 140 Nm.
Have the tightening torque of the wheel bolts checked as soon as possible with a reliable
torque wr

ench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
torque.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not fitted correctly they
cou l

d be released while driving leading to
loss of vehicle control and serious damage.
● Only use wheel bolts which correspond to
the wheel rims in que
stion.
● Never use different wheel bolts.
● The bolts and threads should be clean, free
of oil
and grease and easy to thread.
● To loosen and tighten the wheel bolts, al-
way
s use the wheel brace supplied with the
vehicle.
● Loosen the wheel bolts only about one turn
before r
aising the vehicle with the jack.
● Never grease or lubricate wheel bolts or the
wheel hub thre
ads. Although they have been
tightened to the prescribed torque, they
could come loose while driving.
● Never loosen the bolted joints of wheel
rims with bo
lted ring trims. ●
If the wheel bo

lts are not tightened to the
correct torque, they may come loose while
driving, and the bolts and rims may come
out. If the tightening torque is too high, the
wheel bolts and threads can be damaged. Raising the vehicle with the jack

brace ››› Fig. 70, unscrew the slackened
wheel bolts and place them on a clean sur-
face.
● Take off the wheel.
Putting on the s
pare wheel
Check the direction of rotation of the tyre
››› page 50.
● Fit the wheel.
● Screw on the anti-theft locking bolt with
the adapt
er in position ››› Fig. 67 2 or
3 clockwise and tighten gently.
●
Replace the other wheel bolts and tighten
s ligh
tl

y using the hexagonal socket on the
end of the wheel brace.
● Lower the car with the jack.
● Tighten all of the wheel bolts clockwise
›››
. Tighten the bolts in diagonal pairs (not
in a c ir
c
le).
● Put the caps, trim or full hubcap back on
›››
page 46. WARNING
If the wheel bolts are not treated suitably or
not tight ened t

o the correct torque then this
could lead to loss of vehicle control and to a
serious accident.
● All the wheel bolts and hub threads should
be cle
an and free of oil and grease. The wheel bolts should be easily tightened to the cor-
rect
t

orque.
● The hexagonal socket in the wheel brace
should be u
sed for turning wheel bolts only.
Do not use it to loosen or tighten the wheel
bolts. Tyres with directional tread pattern
Tyres with directional tread pattern have
been des
igned t

o operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread ›››
 page 294.
Always observe the indicated direction of ro-
tation in order to guarantee optimum grip
and help avoid aquaplaning, excessive noise
and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation.
Subsequent work ●
On alloy wheels: repl
ace the wheel bolt
caps.

● Check the tyre pressure of the newly moun-
ted tyr
e as soon as possible.
● If the vehicle is fitted with a tyre monitoring
syst
em, this should be “reprogrammed” if
necessary whenever a tyre is changed
›››  page 234.
● Have the tightening torque of the wheel
bolts c
hecked as soon as possible with a tor-
que wrench ››› page 48. Meanwhile, drive
carefully.
Snow chains
Use When using snow chains, applicable local
l
e
gi

slation and maximum permitted speed
limits must be observed.
In winter weather, snow chains not only help
to improve grip but also improve the braking
capacity.
Snow chains must only be mounted on the
front wheels , even on all-wheel drive vehi-
cles, and only with the tyre and rim combina-
tions listed below:

Self-help
The chocks should be placed directly in front
and behind the wheel and on
ly
be used on
firm ground. WARNING
If the folding chocks are assembled or used
incorr ectly

, an accident may occur and seri-
ous injury caused.
● Never use damaged chocks.
● Never use chocks to immobilize the vehicle

Not all Alhambra models have the TMS (Tyre
Mobility System).
If a tyre needs to be changed the tools neces-
sary are available at spare parts dealers:
● Jack,
● box spanner for wheel bolts,
● tool to remove wheel bolt caps
The tyre
s mounted on the vehicle are anti-
puncture. The wheels should only be
changed when switching from summer to
winter tyres or vice-versa. See ›››
page 293 The vehicle only comes with the necessary
tool

s for changing wheels if factory supplied
with winter tyres. If this is not the case, you
need to go to a specialised workshop to get
the wheels changed.
You should only change the wheels yourself if
the vehicle is parked in a safe place, you are
familiar with the procedure and safety stand-
ards and you have all the necessary tools!
Otherwise, you should seek professional as-
sistance. WARNING
Changing a wheel can be dangerous, espe-
ci a

lly on the hard shoulder. Please observe
the following rules to minimise the risk of in-
jury:
● Stop the vehicle safely as soon as possible.
Park at
a safe distance from surrounding traf-
fic to change a wheel.
● When changing a wheel, keep all passen-
gers, and p
articularly children, a safe dis-
tance away from the work area.
● Turn on the hazard warning lights to warn
other roa
d users.
● Ensure the ground on which you park is flat
and solid. If nec
essary, support the jack on a
wide solid base.
● If you are changing a wheel yourself, you
should be f
amiliar with the required proce-
dure. Otherwise, you should seek professio-
nal assistance. ●
Only u

se suitable tools that are not dam-
aged when changing a wheel.
● Always stop the engine, turn on the elec-
tronic p
arking brake and place the gear selec-
tor lever in position P, for an automatic gear-
box, or engage a gear for a manual gearbox to
reduce the risk of the vehicle moving acciden-
tally.
● Have the tightening torque of the wheel
bolts
checked as soon as possible with a reli-
able torque wrench. WARNING
If the wheel trims are not appropriate or not
fitted c orr

ectly, they could cause major acci-
dents or damage.
● Incorrectly mounted wheel trims may come
off whil
e driving and endanger other road
users.
● Damaged trims must never be mounted on
the wheels.
● Alw

ays ensure that the brake ventilation
and coolin
g is not cut off or blocked. This is
also valid if hubcaps are fitted later. If there
is not enough air, you may require signifi-
cantly longer braking distances. CAUTION
Remove and remount wheel trims taking care
to av oid d

amage to the vehicle. 85

Driver assistance systems
● Do not driv
e f
aster than a pedestrian.
● Do not stop in the water, use reverse gear
or switc
h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water.
The Start/Stop system must be deactivated
when driving through flooded areas WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeu
vres. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses c
orrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. Driver assistance systems

g and stability systems
Brake assist systems The brake assist systems ESC, ABS, BAS, ASR
and EDL on
ly

operate when the ignition is
switched on. They contribute significantly to
increasing active safety.
Electronic Stability Control (ESC)
ESC reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions. ESC
detects critical handling situations, such as
understeer, oversteer and wheelspin on the
driven wheels. The system stabilises the ve-
hicle by braking individual wheels or by re-
ducing the engine torque.
The ESC has limits. It is important to realise
that the ESC is also subject to the laws of
physics. ESC will not be able to deal with all
situations with which drivers may be faced.
For example, if the road surface changes sud-
denly then ESC will not be useful in all cases.
If the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC will not
provide assistance in the same way as on dry
ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aqua-
planing”), the ESC will not be able to assist the driver to control the vehicle as the loss of
adher
enc

e with the road surface will prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
When driving with a trailer, ESC does not pro-
vide the same amount of vehicle control as
without a trailer.
Adjust your speed and driving style to road,
traffic and weather conditions. ESC cannot
push the limits of the laws of physics; im-
prove the transmission available or maintain
the vehicle on the road if a lack of driver at-
tention creates an inevitable situation. Other-
wise, ESC assists in maintaining vehicle con-
trol in extreme situations and uses the move-
ments of the steering made by the driver to
maintain the vehicle moving in the desired
direction. If the vehicle is driven at such a
speed that it will leave the road before ESC
can intervene then the system cannot pro-
vide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC. The ESC is always
on. The ESC should only be turned off using
the ASR button ›››
Fig. 204 when traction is
insufficient. Always remember to turn on the
ASR once more when the vehicle has traction
again. »

Operation
Anti-lock system (ABS)
ABS c
an pr
event the wheels from locking dur-
ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even
during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remov
e your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
brakin
g force!
● Maintain vehicle direction when braking
ful
ly.
● When the brake pedal is released or when
the brake f
orce is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
expect the ABS to reduce the braking dis-
tance under any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy and slippery ground.
When driving on loose ground, the all-terrain
configuration of the ABS is automatically
turned on. When ABS is activated, the front
wheels may lock briefly. This shortens the
braking distance in off-road situations as the
wheels are prevented from digging into loose
surfaces. All-terrain ABS only intervenes
when driving in a straight line. When the front wheels are turned, the normal ABS is
activated.
Br

ake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively.
¡Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control when accelerating (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. The ASR makes
some situations easier, for example, when
starting, accelerating or going uphill, even in
unfavourable road conditions.
The ASR can be switched on or off manually
››› page 207.
Electronic differential lock system (EDS)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel and directs the power to the other drive
wheels. T
o prevent the disc brake of the
braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive
loads. The EDL will switch on again automati-
cally when the brake has cooled down.
Electronic drive torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected.

wheel to vibrate and require the driver to take
active control of the steering:
● If the limits inherent to the system are
reac
hed.
● If the maximum rotational torque during
the correctiv

Beadlock wheel rims
Beadlock wheel rims have various compo-
nents. These are joined together by special
bolts using a special procedure. This ensures
good performance, a better seal, improved
safety and wheel run out. Therefore, worn
rims should always be replaced and must on-
ly be repaired in a specialised workshop.

w

ith bolted trims
Wheel rims may be fitted with interchangea-
ble trim parts which are attached to the rim
using self-locking bolts. Worn trims should
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

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

● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
