preheating.The indicator lamp
 lights up while the glow plugs are preheating. When
the indicator lamp goes out the engine should be started straight away. When
the engine is warm, or at outside temperatures above +8°C, the indicator
lamp will only light up very briefly.
Note
•
If the glow plug indicator lamp should start flashing while the vehicle is
moving, this indicates a fault in the engine management system. The engine
should be serviced without delay.
•
If the indicator lamp fails to light up when the ignition is switched on, this
can mean that the glow plug system is defective. The engine should be
serviced.
Brake system

The warning lamp flashes when the handbrake is applied, or
if the brake fluid level is too low or if there is a fault in the ABS
system.If the warning lamp
 flashes (and the handbrake is not applied), stop the
vehicle and check the brake fluid level ⇒ ⇒ page 222.
If a failure should occur in the ABS, the ABS warning lamp

 ⇒ . Handbrake applied
The warning lamp
 also lights up when the handbrake is applied. In addi-
tion to this, the handbrake warning ⇒page 76 switches on after driving for 3
seconds at a speed above 5 km/h.
WARNING
•
Before opening the bonnet and checking the brake fluid level, observe
the warning information in ⇒ page 213, “Work in the engine compart-
ment”.
•
If the brake warning lamp does not go out, or if it lights up when
driving, the brake fluid level in the reservoir is too low and this may cause
an increased accident risk. Stop the vehicle and do not drive on. Obtain
technical assistance.
•
If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that the control funct ion of the ABS is out of action. As
a result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent danger of skidding. Drive carefully to the
nearest specialist garage and have the fault rectified.

72CD and radio displayIf the radio is switched on and no Priority 2 faults are indicated by the auto-
check control, the “OK” symbol will go out and the display will show the name
or frequency of the selected radio station and various other information,
depending on the type of radio fitted.
When in CD mode*, the display will show the current track.
These displays appear in addition to the display on the radio itself.
Ambient temperature displayThe ambient temperature is shown in the display when the ignition is
switched on ⇒fig. 49.
At temperatures below +5°C a snowflake symbol appears next to the temper-
ature display. This is to warn the driver to take extra care when there is a risk
of ice on the road. When the vehicle is stationary or travelling at very low
speeds, the temperature displayed may be slightly higher than the actual
ambient temperature as a result of heat coming from the engine.
If the vehicle has an air conditioning and the display is changed over to °F
(degrees Fahrenheit), the ambient temperature display automatically
changes over to °F ⇒ page 157.
WARNING
Do not rely on the ambient temperature display as an ice warning. Please
bear in mind that there may be ice on the roads even at ambient tempera-
tures of +5°C – beware of ice patches.

Yellow symbols are used to indicate a Priority 2 fault (warning).
Yellow symbols are accompanied by
one warning chime. The function indi-
cated should be checked as soon as possible. If several Priority 2 faults are
detected at the same time, the symbols are displayed one after the other for
about 2 seconds at a time.
Fuel level low

When this symbol
 comes on for the first time, there are about 8 to 10 litres
of fuel left in the tank. You should fill up as soon as possible ⇒page 208.
Diesel particulate filter obstructed

If the symbol
 lights up, you may be able to contribute towards automatic
filter cleaning by driving in the right manner. You should drive at a speed of
at least 60 km/h for about 15 minutes in 4th or 5th gear, at an engine speed
of around 2000 rpm. The increase in temperature will burn off any soot in the
filter. When cleaning is successful, the symbol switches off.
If the light on symbol
 does not go off, take the vehicle to a specialist
garage to repair the fault.
For further information on the diesel particulate filter, see ⇒page 183.
WARNING
It is essential that you adjust your sp eed to suit the weather, road, terrain
and traffic conditions. The recommended driving speed must never lead to
the driver disregarding the traffic regulations.Light sensor/ rain sensor faulty

Unlocking and locking
104Anti-theft alarm system*Description
The system triggers an alarm if anyone attempts to break into
the vehicle.The anti-theft alarm helps to prevent the vehicle being broken into or stolen.
If the system senses interference with the vehicle, it triggers an audible and
visible alarm.
How is the system enabled?
The anti-theft alarm system is enabled automatically when the vehicle is
locked with the remote control or by turning the key in the driver's door (if the
door is closed). The system is enabled about 30 seconds after the vehicle is
locked.
How is the system disabled?
The anti-theft alarm is only disabled when the vehicle is unlocked using the
remote control. The vehicle will lock again automatically if none of the doors
is opened within 60 seconds after pressing the remote control button.
If the vehicle is unlocked by turning the key in the driver's door, all the other
doors, the tailgate and the tank flap will remain locked.
If the vehicle has been unlocked with the key in the driver's door, the key must
be inserted in the ignition lock and the ignition switched on within 15
seconds of opening the door in order to disable the alarm. The alarm will be
triggered if the ignition is not switched on within 15 seconds.
When does the system trigger the alarm?
The following parts of the car are monitored when the vehicle is locked:•
Engine compartment (bonnet)
•
Boot
•
Doors
•
Tilt angle (tow-a way protection)
•
Ignition
•
Radio (only with a factory-fitted SEAT radio)
•
Interior ⇒page 105
If any of the named areas are entered, the alarm will be triggered.
How is the alarm disabled?
The alarm can be switched off by unlocking the vehicle using the remote
control, or by switching on the igniti on with the key, thus “disabling” the
alarm system. The alarm will also switch off when it comes to the end of its
cycle.
Indicators
The indicators flash briefly when the vehicle is locked to confirm that the
doors, the engine bonnet and the tailgate are properly closed and locked.
If the indicators do not flash, check the doors, the bonnet and the tailgate to
make sure they are properly closed. The indicators will also flash briefly if one
of the doors or the tailgate or engine bonnet are closed after the alarm system
has been enabled.
LED
When the vehicle is locked, the LED on the top of the driver's door trim will
flash rapidly for about 30 seconds and then continue flashing slowly. This is
to indicate that the anti-theft alarm system (including the interior monitor
and tow-away protection) is operative. If the LED lights up continuously for
about 30 seconds when the vehicle is locked instead of flashing, this means
the alarm system is not working properly.Note
•
To make sure that the alarm is fully operative when leaving the vehicle,
briefly check that all the doors and windows and the sun roof* are closed.

Trailer towing187
Safety First
Operating instructions
Practical tips
Te c h n i c a l D a t a
Where possible, operate the trailer with the maximum permitted
draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your car, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. The two exterior mi rrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 116.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have vehicle serviced between
services.
Notes on towing
Towing a trailer involves additi onal attention by the driver.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced we ight distribution.
Speed
The stability of the car and trailer is reduced with increasing speed. Therefore,
it is advisable not to drive at the maximum permissible speed in an unfavour-
able road, weather or wind conditions. This especially applies when driving
downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying. Never try to stop the “snaking” by increasing speed.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then more severely. This will prevent brake
tapping by the trailer wheels when they lock. Select a low gear in due course
before going down a steep downhill. This enables you to use the engine
braking to slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer load.
They can be purchased and installed at a Dealer.
Reheating
When climbing long hills in hot weather wi th the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning light
 in the instrument cluster should start
flashing, stop the car and let the engine cool down by running it at idling
speed for a few minutes.
