2012 Seat Alhambra ECU

296Checking and refilling levels
● the idling speed is increased so that the alternator provides more elec-
tricity.
● where necessary, the power of the most powerful consumers is reduced
or even completely disconnected.
● On starting the engine, the power supply from the 12-volt sockets 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 does the battery run flat?
● When stationary for a long time without starting the engine, particularly
if the ignition is switched on.
● Use of electrical consumers with the engine switched off.
● If the auxiliary heater is running ⇒ page 165.
WARNING
Incorrectly securing the battery or using the wrong battery can cause
short-circuits, fire and serious injuries.
● Always use only maintenance free batteries that do not run flat alone
and whose properties, specifications and size correspond to the stand-
ard battery. The specifications are indicated on the battery case.
WARNING
A highly explosive mixture of gases is released when the battery is under
charge.
● The batteries should be charged in a well-ventilated room only.
● Never charge a frozen or recently thawed battery. A flat battery can al-
so freeze at temperatures close to 0 °C (+32 °F).
WARNING (Continued)
● Always replace a battery which has frozen.
● Battery cables not correctly connected may cause a short circuit. Re-
connect first the positive cable and then the negative cable.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Never plug accessories supply current, such as solar panels or a battery
charger, to the 12-volt sockets or the cigarette lighter. This could damage
the vehicle's electrical system.
For the sake of the environment
● Dispose of the battery in an environment-friendly manner. Batteries con-
tain toxic substances such as sulphuric acid and lead.
● Battery acid can contaminate the environment. Collect any spilt service
fluids and allow a dispose of them correctly. 

300Wheels and tyres
Wheel rims
The design of wheel bolts is matched to the rims. If different 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 ⇒ page 309.
For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel.
The tyres and rims approved by SEAT are specially matched to the character-
istics of the vehicle and are critical to good road holding and safe handling.
Wheel bolts
Wheel bolts must be tightened to the correct torque ⇒ page 309.
Beadlock wheel rims
Beadlock wheel rims have various components. 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 only be repaired in a Technical Service.
SEAT recommends visiting a Technical Service ⇒ 
.
Wheel rims with bolted trims
Wheel rims may be fitted with interchangeable trim parts which are attach-
ed to the rim using self-locking bolts. Worn trims should only be replaced at
a Technical Service. SEAT recommends visiting a Technical Service ⇒ 
.
WARNING
The use of worn or damaged wheel rims could make driving more danger-
ous and result in serious accidents and damage.
● Only wheel rims which have been approved for use with your vehicle
should be used.
● Inspect wheel rims regularly for damage and replace as required.
WARNING
If the bolted joints of wheel rims with bolted ring trims are not correctly
tightened or loosened, this could result in serious accident.
● Never loosen the bolted joints of wheel rims with bolted ring trims.
● Any work relating to wheel rims with bolted rims should be carried
out at qualified workshop. SEAT recommends visiting a Technical Service.

Replacement of new tyres and wheel rims
New tyres
● When tyres are new, drive with extreme caution for the first 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 tyres of the same type, size
(rolling circumference) and the same tread pattern.
● The tread depth of new tyres may vary, according to the type and make
of tyre and the tread pattern.
Replacing tyres
● Where possible, always replace both wheels on an axle (both wheels on
the front axle or both wheels on the rear axle) ⇒ 
.
● Old tyres should only be replaced by SEAT approved tyres for the vehicle
in question, and in accordance with the maximum permitted size, diameter,
load and speed capacity.
● Never use tyres which are larger than SEAT approved tyres. If the tyres
are too big, they may knock or rub against the chassis or other components,
resulting in damage. 

or

Only use the tool supplied with the vehicle to loosen the wheel bolts.
Loosen the wheel bolts only about one turn before raising the vehicle with
the jack. If the wheel bolt is very tight, you may be able to loosen it by pushing down
on the end of the wheel brace carefully with your foot. Hold on to the car for
support and take care not to slip.
Loosening wheel bolts
●
Fit the wheel brace as far as it will go over the wheel bolt ⇒ fig. 183.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒ 
.
Loosening anti-theft wheel bolts
For wheels with full hubcap, the anti-theft wheel lock must be threaded into
position ⇒ fig. 184 2
or 3 before mounting the hubcap. Otherwise it will
not be possible to mount the full hubcap.
● Take the adapter for anti-theft wheel bolts out of the vehicle tool kit.
● Insert the adapter onto the wheel bolt.
● Fit the wheel brace onto the adapter as far as possible.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒ 
.
Important information about wheel bolts
The wheel rims and bolts have been designed to be fitted to factory op-
tions. If different 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 wrench.
If wheel bolts are rusty and it is difficult to tighten them, the threads should
be replaced and cleaned before checking the torque. 

ing lights.
Always fulfil legal requirements for securing a broken down vehicle. In a
number of countries it is now obligatory, for example, to turn on the hazard
warning lights and use a reflective safety vest ⇒ page 318.
When being towed with the hazard warning lights on, a change in direction
or traffic lane can be indicated as usual using the turn indicator lever. The
hazard lights will be interrupted temporarily.
Checklist

If the vehicle power supply should ever fail (discharged battery, etc.) and
the vehicle has to be pushed or towed, the selector lever must first be
moved to position N using the manual release mechanism. The emergency release mechanism is located underneath the gearbox cover
panel to the right-hand side. To release the gear selector lever mechanism,
a suitable tool is required, for example a screwdriver.
Preparations
●
Apply the parking brake. If the parking brake cannot be activated in the
vehicle must be secured otherwise so that it cannot move.
● Switch the ignition off.
To remove the gearbox cover panel
● Pull the cover up around the dust guard on the gear selector lever
⇒ fig. 197.
● Take the cover off by passing it over the gear selector lever ⇒ 
.
Manual release of selector lever
● Press the release lever ⇒ fig. 198 in the direction of the arrow and hold
it in this position.
● Press the lock button ⇒ fig. 197 1
on the gear selector lever knob and
place the gear selector lever in the N position.
WARNING
Never move the gear selector lever from the position P while the electron-
ic parking brake is deactivated. Otherwise, the vehicle may accidentally
move off on hills or steep slopes causing serious accidents.
CAUTION
If the vehicle is moved on its wheels with the engine stopped and the selec-
tor lever in position N for a prolonged period of time and at high speed, for
example for towing, then the automatic gearbox will be damaged. 
