68Instruments and warning/control lamps
Coolant temperature gauge
For vehicles with no coolant temperature gauge, a control lamp appears for
high coolant temperatures  ⇒ page 257. Take into account the ⇒ .
The coolant temperature gauge 2
⇒ Fig. 38 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Engine cold
If only the diodes in the lower part of the scale light up, this indicates that
the engine has not yet reached operating temperature. Avoid high revs and
heavy acceleration and do not make the engine work hard.
Normal temperature
If in normal operations, the diodes light up until the central zone, it means
that the engine has reached operating temperature. At high outside temper-
atures and when making the engine work hard, the diodes may continue
lighting up and reach the upper zone. This is no cause for concern, provided
the control lamp  does not light up on the instrument panel digital dis-
play.
Heat range
When the diodes light up in the upper area of the display and the control
lamp appears  on the instrument panel display, the coolant temperature
is excessive ⇒ page 257.
CAUTION
● To ensure a long useful life for the engine, avoid high revs, driving at
high speed and making the engine work hard for approx. the first 15 mi-
nutes when the engine is cold. The phase until the engine is warm also de-
pends on the outside temperature. If necessary, use the engine oil tempera-
ture* as a guide ⇒ page 77
● Additional lights and other accessories in front of the air inlet reduce the
cooling effect of the coolant. At high outside temperatures and high engine
loads, there is a risk of the engine overheating.
● The front spoiler also ensures proper distribution of the cooling air when
the vehicle is moving. If the spoiler is damaged this can reduce the cooling
effect, which could cause the engine to overheat. Seek specialist assis-
tance. 

Air conditioning
Instructions for use of the air conditioner
The interior cooling system only works when the engine is running and fan
is switched on.
The air conditioner operates most effectively with the windows and the pan-
oramic sliding sunroof closed. However, if the vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows and the panoramic sliding sunroof briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the temperature and the air hu-
midity in the vehicle interior drop. Hence, when the outside air humidity is
high, the windows do not mist over and comfort for the vehicle occupants is
improved:
With manual air conditioning
● Switch off air recirculation.
● Set the fan to the required setting.
● Turn the temperature control to the centre position.
● Open and direct all the air outlets in the dash panel.
● Turn the air distribution control to the required position.
● Press the button 
to switch on the cooling system. The button will
light up.
With Climatronic
● Press button 
.
● Set the temperature to +22 °C (+72 °F).
● Open and direct all the air outlets in the dash panel.
Climatronic: change the temperature unit on the screen of the radio or on
the factory-fitted navigation system
Changing the temperature display from Celsius to Fahrenheit on radio or on
the factory-fitted navigation system is done using the menu on the instru-
ment panel ⇒ page 73. The cooling system cannot be activated
If the air conditioning system cannot be switched on, this may be caused by
the following:
●
The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than approximately +3 °C (+38 °F).
● The air conditioner compressor has been temporarily switched off be-
cause the engine coolant temperature is too high.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
Special Characteristics
If the humidity and temperature outside the vehicle are high, condensation
can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak!
Note
After starting the engine, any residual humidity in the air conditioner could
mist over the windscreen. Switch on the defrost function as soon as possi-
ble to clear the windscreen of condensation. 

–Turn the ignition key to position 1
to switch off the ignition.
Preheating is produced in Diesel vehicles  when the ignition is
switched on.
Starting up the engine
– Manual gearbox: Press the clutch pedal all the way down and
move the gearbox lever into neutral.
– Automatic gearbox : Press the brake pedal and move the selec-
tor lever to position P or N.
– Turn the ignition key to position 3
. The key returns to position
2 automatically. Do not press the accelerator.
Diesel engines can take a few seconds longer than usual to start
on cold days. Therefore the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must remain pressed until the en-
gine starts up. During preheating, the warning lamp  remains lit.
The preheating time depends on the coolant and exterior tempera-
tures. When the engine is at operating temperature or at outside
temperatures above +8 °C (46 °F) the warning lamp  will only
light up for about one second. This means that the engine starts
immediately.
If the engine does not immediately start up, interrupt the starting process
and try again after 30 seconds. To start the engine again, return the key to
position 1
.
Start-Stop System*
If the vehicle is stopped and the Start-Stop system* switches off the engine,
the ignition remains switched on.
Automatic gearbox: Before leaving the vehicle, make sure that the ignition
is switched off and the selector lever is in position P. Driver messages on the instrument panel display
Press the clutch This message appears on vehicles with a manual gearbox if the driver tries
to start the engine without having the clutch pedal pressed. The engine will
only start if you press the clutch pedal.
Press the brake
This message appears on vehicles with an automatic gearbox if the driver
tries to start the engine without having the brake pedal pressed.
Select N or P
This message appears if you try to start or stop the engine when the selec-
tor lever of the automatic gearbox is not in position P or N. The engine can
only start or stop in these positions.
Engage position P; the vehicle can move; doors can only close in position P. For safety reasons, this driver message appears and an audible warning
sounds if the selector lever of the automatic gearbox is not in position P af-
ter you switch off the ignition. Otherwise the vehicle could move.
Gear change: selector lever in the drive position!
This driver message is displayed and a buzzer is sounded when the selector
lever is not in the position P when the driver door is opened. Put the selec-
tor lever in position P; otherwise the vehicle can roll away.
Ignition is switched onThis driver message is displayed and a buzzer is sounded when the driver
door is opened with the ignition switched on. 

CAUTION
If the engine has been running under high load for a long time, there is a
risk of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason, you
should idle the engine for approx. 2 minutes before you switch it off.
Note
● After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched off. It is also possible that the fan
turns itself on once more if the coolant temperature increases due to the
heat accumulated in the engine compartment or due to its prolonged expo-
sure to solar radiation.
● If the vehicle is stopped and the Start-Stop system* switches off the en-
gine, the ignition remains switched on. Make sure that the ignition is
switched off before leaving the vehicle, otherwise the battery could dis-
charge. 
Kick-down
The kick-down feature allows maximum acceleration to be
reached. If the eco*
⇒ page 212 mode has been selected in SEAT Drive Mode*, and
the accelerator is pressed beyond a hard point, the engine power is auto-
matically controlled to give your vehicle maximum acceleration.
WARNING
Please note that if the road surface is slippery or wet, the kick-down fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.
 Handbrake
Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 119 Handbrake be-
tween the front seats
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ Fig. 119.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ Fig. 119 and guide the handbrake lever

Trailer
Note
● Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the ve-
hicle is used frequently for towing a trailer.
● Find out whether special regulations apply to towing a trailer in your
country. 
Ball coupling of towing bracket*
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and caus-
ing injury.
Note
● By law, the ball coupling must be removed if a trailer is not being towed
if it obscures the number plate. 
Driving tips
Driving with a trailer always requires extra care. 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 weight distribution. Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed
in an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slight-
est sign of
snaking. Never try to stop the “snaking” by increasing speed.
Always brake in due course. If the trailer has an overrun brake, apply the
brakes gently at first and then, firmly. This will prevent the jerking that can
be caused by locking of trailer wheels. Select a low gear in due course be-
fore going down a steep downhill. This enables you to use the engine brak-
ing to slow down the vehicle.
Reheating
At very high temperatures and during prolonged slopes, driving in a low
gear and high engine speed, always monitor the coolant temperature gauge
⇒ page 69.
Electronic Stability Control*
The ESC* system helps to stabilise the trailer in case of skidding or rocking. 
