2015 Seat Altea overheating

Operation
●
Due care must be taken to avoid any risk of
fire or explosion.
● When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a
leak. Note
● The values shown in the average fuel con-
sumption and distance to empty indications
on the multifunction display (MFI) 1)
on the in-
strument panel display 2)
are approximate val-
ues only.
● Two different consumption values are given
on the MFI, depending on whether the vehi-
cle is running in gas or petrol mode.
● Please check the fuel level on the fuel level
gauge on the instrument panel ››› page 33.
● If frequent short journeys are made, espe-
cially when the outside temperature is low,
the vehicle will tend to run on petrol more of-
ten than on LPG. Therefore, the petrol tank
may empty before the LPG tank. Engine coolant temperature gauge

Firs
t look at the coolant temperature gauge.
The coolant temperature is too high if the
needle is over the warning area on the dial.
Stop the vehicle, switch the engine off and
wait for it to cool down. Check the coolant
level.
If the coolant level is correct, the overheating
may be caused by a malfunction of the radia-
tor fan. Check the radiator fan fuse and have
it replaced if necessary ››› page 196.
If the control lamp lights up again after driv-
ing on for a short distance, stop the vehicle
and switch the engine off. Contact a Techni-
cal

Service or a specialised workshop.
Coolant level too low

TION MANUAL.
First look at the coolant temperature gauge. If
the needle is in the normal range, top up with
coolant at the earliest opportunity ››› . WARNING
● If your vehicle is immobilised for technical
reasons, move it to a safe distance from traf-
fic. Turn the engine off, turn the hazard lights
on and place the warning triangle.
● Never open the bonnet if you can see or
hear steam or coolant escaping from the en-
gine compartment. Risk of scalding. Wait un-
til you can no longer see or hear escaping
steam or coolant.
● The engine compartment is a dangerous
area. Before carrying out any work in the en-
gine compartment, switch off the engine and
allow it to cool down. Always note the corre-
sponding warnings ››› page 163. Coolant temperature

Operation
●
Do not apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. These materials could catch
fire when the vehicle is being driven. CAUTION
Never run the fuel tank completely dry be-
cause the irregularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel engine particulate filter*
Fig. 130
Vehicle data sticker on back cover of
the Maintenance Programme. Your vehicle is fitted with a DPF (Diesel partic-
ulate filter) if the vehicle data sticker (back
cover of the “Maintenance Programme)” lists
the PR code 7GG or 7MG
››› Fig. 130 .
The die sel
engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex-
ample, multiple short trips) the filter will be
obstructed by soot and  the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you
must perform a cleaning cycle, as indicated
in ››› page 41
. WARNING
● The diesel engine particulate filter may
reach extremely high temperatures; the vehi-
cle should be parked so that the exhaust pipe
does not come into contact with flammable
materials underneath the vehicle. Otherwise
there is a risk of fire. CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-
tent may significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and wear to the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.

Driver assistance systems
The ESC system is always active and cannot
be switched off. The ESC switch only switches
the ASR off.
The ASR can be deactivated when wheel spin
is desirable.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
faces.
● When the vehicle is stuck, to rock it back-
wards and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn. Steering manoeuvre recommendations
This is a complementary safety function in-
cluded in the ESC. This function aids the driv-
er to better stabilize the vehicle in a critical
situation. For example, in case of sudden
braking on a surface with varied adherence,
the vehicle will tend to destabilise its trajec-
tory to the right or to the left. In this case, the
ESC recognises the situation and assists the
driver with a counter steering manoeuvre
from the power steering.
This function simply provides the driver with
a recommended manoeuvre in critical situa-
tions.
The vehicle does not steer itself with this
function, the driver has full control of the ve-
hicle at all times.
WARNING
● Remember that not even the ESC can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To ensure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Electronic differential lock (EDL)*
EDL helps the vehicle to start moving, accel-
erate and climb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels. In case of an EDL fault,
the warning light for ABS lights up
››› page 41 .
At s
peeds of up to approximately 80 km/h
(50 mph), it is able to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally »

Checking and refilling levels
Fig. 141
LPG tank in spare wheel well Before refuelling, turn off the engine and
switch off the ignition and mobile telephone
››› .
Read carefully the instructions on how to use
the LPG pump.
Opening the fuel tank cap
The LPG filler neck is behind the fuel cap,
next to the petrol filler neck.
● The tank flap is located on the rear right-
hand side of the vehicle.
● Open the fuel tank flap.
Refuelling
● Remove the plug from the gas filler mouth
››› Fig. 140 1 .
● Screw the required adapter 2 onto the
LPG gas filler neck. ●
Refuel as indicated in the pump instruc-
tions.
● The fuel tank will be full when the pump
c ompr
essor automatically cuts the supply.
● If you wish to finish refuelling sooner, re-
lease the button on the pump to stop the
flow.
Closing the fuel tank cap
● Unscrew the adapter from the gas filler
neck 2 .
● Screw the cap onto the gas filler neck 1 .
● Close the fuel tank flap. The cover should
be flush with the bodywork. WARNING
Incorrect handling of LPG can cause explo-
sions, fire, serious burns and other injuries.
● LPG is a highly explosive and inflammable
substance.
● Small quantities of LPG may leak out after
refuelling. If LPG comes into contact with the
skin there is a risk of freezing. Note
● The vehicle includes one adapter for the
country in question, the most common one.
We generally recommend that you carry all
the adapters in your vehicle, as some coun-
tries use more than one type of filling sys-
tem. ●
If the outside temperature is very high, the
protection against overheating for the LPG
pump may disconnect automatically.
● If the outside temperature is very high, the
pressure of the LPG tank may be equal to or
greater than that of the gas tank of the LPG
pump. In this case, refuelling will be physi-
cally impossible.
● The filling nozzles of LPG pumps can differ
in the way they are operated. If you do not
know, ask a qualified employee at the petrol
station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system. 161

tyre cannot be sealed with the anti-puncture
kit. Do not continue driving. You should ob-
tain professional assistance ››› .
● Disconnect the air compressor and unscrew
the flexible inflator tube from the tyre valve.
● When the tyre pressure is between 2.5 and
2.0 bars, immediately continue driving with-
out exceeding 80 km/h (50 mph).
● After 10 minutes
, Check the pressure again
›
›› page 189. WARNING
When inflating the wheel, the air compressor
and the inflator tube may become hot.
● Protect hands and skin from hot parts.
● Do not place the hot flexible inflator tube or
hot air compressor on flammable material.
● Allow them to cool before storing the de-
vice.
● If it is not possible to inflate the tyre to at
least 2.0 bars (29 psi / 200 kPa), the tyre is
too badly damaged. The sealant is not in a
good condition to seal the tyre. Do not con-
tinue driving. Seek specialist assistance. CAUTION
Switch off the air compressor after a maxi-
mum of 8 operational minutes to prevent it
from overheating! Before switching on the air compressor again, let it cool for several mi-
nutes.
Check after 10 minutes of driving
Screw the inflator tube
››› Fig. 162 5 again
and check the pressure on the gauge 6 .
1.3 bar (19 psi / 130 kPa) and lower:
● Stop the vehicle! The tyre cannot be sealed
sufficiently with the tyre mobility set.
● You should obtain professional assistance
››› .
1.4 bar (20 psi / 140 kPa) and higher:
● Set the tyre pressure to the correct value
again.
● Carefully resume your journey until you
reach the nearest specialised workshop with-
out exceeding 80 km/h (50 mph).
● Have the damaged tyre replaced. WARNING
Driving with an unsealed tyre is dangerous
and can cause accidents and serious injury.
● Do not continue driving if the tyre pressure
is 1.3 bar (19 psi / 130 kPa) and lower.
● Seek specialist assistance. Jump-starting
