2014 Seat Leon 5D engine

Air conditioning
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop. Special Characteristics
If the humidity and temperature outside the
vehicle are high,
condensation
can drip off
the ev
aporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air conditioner could mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents

On the dash panel: air vents Air vents
To ensure proper heating, cooling and venti-
lation in the vehicle interior, air vents
››› Fig. 140 1 should remain open.
● Turn the corresponding thumbwheel (de-
tail) in the required direction to open and
close the air vents. When the thumbwheel is in the

position, the corresponding air vent
i

s closed.
● Change the air direction using the ventila-
tion grille lever.
There are other additional, non-adjustable air
vents in the dash panel 2 , in the footwell
and in the rear area of the interior. Note
Food, medicine and other heat or cold sensi-
tive objects should never be placed in front of
the air outlets as they may be damaged or
made unsuitable for use by the air coming
from the air vents. 127

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 re-
main pressed until the engine starts up. Dur-
ing preheating, the warning lamp  remains
lit.
The preheating time depends on the coolant
and exterior temperatures. With the engine at
operating temperature, or at outside temper-
atures above +8°C, the warning lamp  will 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 vehi-
cle, make sure that the ignition is switched
off and the selector lever is in position P.

Operation
WARNING
● Never run the engine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
extreme load conditions until the engine has
reached its normal operating temperature,
otherwise this can damage the engine. For the sake of the environment
Do not warm up the engine by idling it. You
should drive off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it is difficult to turn the ignition key to
the position 1 , turn the steering wheel to
both sides to release the steering lock.
● When starting from cold, the engine may be
a little noisy for the first few seconds until oil
pressure has built up in the hydraulic valve
lifters. This is quite normal, and no cause for
concern.
● If the vehicle battery is disconnected and
reconnected, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up.
● Vehicles with automatic gearbox: after
switching off the ignition, you can only re-
move the ignition key if the selector lever is in position “P” (parking lock). Next, the se-
lector lever is locked.
Switching off the engine with the key
Switching off the engine
– Stop the vehicle.
– Turn the ignition key to position 1 ›››
Fig. 141.
En g
aging the steering wheel lock
In vehicles with automatic gearbox, the igni-
tion key can only be removed when the selec-
tor lever is in position P.
– Remo

ve the key from the ignition in posi-
tion 1
››› Fig. 141
›
›› .
– Turn the steering wheel until you hear it en-
gage.
Possible vehicle theft is prevented with the
steering lock engaged. WARNING
● Never switch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury. ●
Never remove the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
leave the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. 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
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore 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 exposure to solar ra-
diation.
● If the vehicle is stopped and the Start-Stop
system* switches off the engine, the ignition 130

Driving
remains switched on. Make sure that the igni-
tion is switched off before leaving the
vehicle, otherwise the battery could dis-
charge.
Braking and parking
Using the handbrake Fig. 142
Handbrake between the front seats. The handbrake should be applied firmly to
prevent the vehicle from accidentally rolling
away.
Always apply the handbrake when you leave
your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly
››› Fig. 142 . R
el easing the handbrake
– Pull the lever up slightly and press the re-
lease knob in the direction of the arrow
››› Fig. 142 and guide the handbrake lever
down f

ully ››› .
Always pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The handbrake warning lamp  lights up
when the handbrake is applied and the igni-
tion switched on. The warning lamp turns off
when the handbrake is released.
If you drive faster than 6 km/h (4 mph) with
the handbrake on, the following message*
will appear on the instrument panel display: HANDBRAKE ON. You will also hear an audible
warning. WARNING
● Never use the handbrake to stop the vehi-
cle when it is in motion. The braking distance
is considerably longer, because braking is
only applied to the rear wheels. Risk of acci-
dent!
● If the handbrake is only partially released,
this will cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehicle. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
plied when the vehicle is parked.
Always note the following points when park-
ing the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. Turn the steering wheel
slightly to engage the steering lock.
– Never leave a vehicle key in the vehicle.
Additional notes on parking the vehicle on
gradients:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll. ● If the vehicle is parked facing downhill,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill
, turn
the fr ont

wheels so that they point away from
the kerb

The essentials

Operation
● Secure the vehicle as usual by applying the
handbrake firmly and putting it in 1st gear. WARNING
● Take measures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
could ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehicle when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They could set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever.
● Depending on weather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Manual gearbox
Changing gears Read the additional information carefully
›››  page 24
In some countries the clutch pedal must be
fully pressed down for the engine to start. Selecting reverse gear
● Engage reverse gear only when the vehicle
is stopped.
Changing down gears
While driving, changing down a gear must al-
ways be done gradually, i.e. to the gear di-
rectly below and when the engine speed is
not too high ››› . Changing down while by-
passing one or various gears at high speeds
or at high engine speeds can damage the
clutch and the gearbox, even if the clutch
pedal remains depressed ››› .
WARNING
When the engine is running, the vehicle will
start to move as soon as a gear is engaged
and the clutch released. This is also the case
with the electro-mechanical parking brake
switched on.
● Never engage reverse gear when the vehi-
cle is moving. WARNING
If the gear is changed down inappropriately
by selecting a gear that is too low, you may
lose control of the vehicle, causing an acci-
dent and serious injuries. CAUTION
When travelling at high speeds or at high en-
gine speeds, selecting a gear that is too low can cause considerable damage to the clutch
and the gearbox. This can also occur if the
clutch pedal is pressed and held and it does
not engage.
CAUTION
To prevent damage and avoid premature
wear, please observe the following:
● Do not rest your hand on the gear lever
while driving. The pressure applied by your
hand is transmitted to the gearbox selector
forks.
● Always ensure that the vehicle is complete-
ly stopped before engaging the reverse gear.
● Always press the clutch to the floor when
changing gears.
● Never hold the vehicle “on the clutch” on
hills with the engine on. Automatic gearbox/DSG
automatic gearbox*
Introduction Your vehicle is equipped with an electronical-
ly controlled manual gearbox. Torque be-
tween the engine and the gearbox is trans-
mitted via two independent clutches. They re-
place the torque converter found on conven-
tional automatic gearboxes and allow for
132

smooth, uninterrupted acceleration of the
vehicle.
The tiptronic
system allows the driver to
c
hange gears manually if desired

The selector lever position engaged is high-
lighted on the display in the instrument clus-
ter. With the selector lever in the manual
gearbox positions G, D, E and S, the engaged
gear is also indicated on the display.
P – Parking lock
When the selector lever is in this position,
the driven wheels are locked mechanically.
The parking lock must be engaged only when
the vehicle is stationary

› .
The interlock button (the button on the selec-
tor lever handle) must be pressed in and si-
mu lt

aneously the brake pedal must be de-
pressed before moving the selector lever ei-
ther in or out of position P. R – Reverse gear
Reverse gear must be engaged only when the
vehicle is
stationary
and the engine is idling
››› .
To move the selector lever to position R, the
interlock button must be pressed in and at
the s ame time the br

ake pedal must be de-
pressed. The reverse lights come on when
the selector lever is in the R position with the
ignition on.
N – Neutral (idling)
With the selector lever in this position, the
gear is in neutral.
D/S – Permanent drive (forward) position
The selector lever in the D/S position enables
the gears to be controlled in normal mode (D)
or Sport (S). To select Sport mode (S), move
the selector lever backwards. Moving the lev-
er again will select normal mode (D). The se-
lected driving mode is shown on the instru-
ment panel display.
In
normal mode (D), the gearbox automatical-
ly selects the best gear ratio. This depends
on the engine load, the road speed and the
dynamic gear control programme (DCP).
Sport mode (S) must be selected for a sporty
driving style. This setting makes use of the
engine's maximum power output. When ac-
celerating the gear shifts will be noticeable. The brake pedal must be pressed when mov-
ing the selector lever from D/S to N if the ve-
hicle is stationary or at speeds below 5 km/h
(3 mph)
››› .
Under certain circumstances (e.g. when driv-
ing in mountains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 135 , in order to
manually select g
ear
ratios to suit the driving conditions. WARNING
● Take care not to accidentally press the ac-
celerator pedal when the vehicle is stopped.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident.
● Never move the selector lever to R or P
when driving. Failure to follow this instruc-
tion could result in an accident.
● With selector lever in any position (except
P) the vehicle must always be held with the
foot brake when the engine is running. This is
because an automatic gearbox still transmits
power even at idling speed, and the vehicle
tends to “creep”). The accelerator pedal must
on no account be pressed inadvertently when
a gear is engaged with the vehicle stationary.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident. » 133

Operation
●
While you are selecting a gear and the vehi-
cle is stopped with the engine running, do
not accelerate. Failure to follow this instruc-
tion could result in an accident.
● As a driver you should never leave your ve-
hicle if the engine is running and a gear is en-
gaged. If you have to leave your vehicle while
the engine is running, you must apply the
handbrake and engage the parking lock (P).
● To avoid accidents, apply the handbrake
and put the selector lever in position P before
opening the bonnet and working on the vehi-
cle with the engine running. Please always
observe the important safety warnings
››› page 198, Work in the engine compart-
ment. Note
● If the selector lever is moved accidentally
to N when driving, release the accelerator and
let the engine speed drop to idling before se-
lecting gear range D or S again.
● Should the power supply to the selector
lever be interrupted in position P, the selector
lever will be locked. If this should happen the
manual release can be used ››› page 229. Selector lever lock

Selector lever lock. The selector lever lock prevents gears from
being engaged inadvertently, so that the ve-
hicle is not set in motion unintentionally.
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time
pr e
ss in the interlock button.
Automatic selector lever lock
With the ignition switched on, the selector
lever is locked in the positions P and N. The
brake pedal must be pressed to release the
lever while pressing the release button if the
selector lever is in the position P. As a re-
minder for the driver, with the lever in posi-
tions P or N the following message will be
shown on the display: When stationary, apply footbrake while se-
lecting a gear.
The selector lever lock only works if the vehi-
cle is stationary or driving at speeds up to 5
km/h. At higher speeds the selector lever
lock in the N position is disengaged automat-
ically.
The selector lever lock is not engaged if the
selector lever is moved quickly through posi-
tion N (e.g. when shifting from R to D). This
makes it possible, for instance, to rock the
vehicle “backwards and forwards” if it is
stuck. The selector lever lock engages auto-
matically if the brake pedal is not depressed
and the lever is in position N for more than
about two seconds.
Interlock button
The interlock button on the selector lever
handle prevents the driver from inadvertently
engaging certain gears. Press the button in
to disengage the selector lever lock. The se-
lector lever positions in which the interlock
button has to be pressed are shown in the il-
lustration, highlighted in colour ››› Fig. 143.

Operation
When accelerating, the gearbox automatical-
ly shifts up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
overrevving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.
Driving tips The gearbox changes gear ratios automatical-
ly as the vehicle moves.
The engine can only start with the selector
lever in the position P or N. At low tempera-
tures, below -10°C (50°F), the engine can on-
ly start with the selector lever in the position
P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the
button on the selector lever handle), move
the selector lever to the desired position,
for instance D
› ››
page 133, and release the
interlock button.
– Wait for the gearbox to engage the gear (a
slight movement can be felt). –
Release the brake and press the accelerator
››› .
Stopping briefly – Apply the foot brake to hold the vehicle
briefly when stationary (for instance at traf-
fic lights). Do not press the accelerator.
Stopping/Parking
If the driver door is opened and the selector
lever is not in position P, the vehicle could
move. The driver message will be:  Gear
change: selector lever in the drive position!. Additionally, a buzzer will sound.
– Press and hold the brake pedal ››› .
– Apply the handbrake.
– Move the selector lever to position P.
Holding the car on a hill – Always apply the brake pedal firmly to pre-
v ent

the vehicle from “moving backwards;
if necessary, apply the handbrake” ››› .

Once you have engaged a gear press the
accelerator carefully and disengage the
handbrake.
Moving off uphill in vehicles with Hill start
assistant* – Once you have engaged a gear, release the
footbrake and press the accelerator
››› page 147, Hill driving assistant*.
Driving down hills: in some situations (on
mountain roads or when towing a trailer or
caravan) it can be advantageous to switch
temporarily to the manual gearbox pro-
gramme so that the gear ratios can be selec-
ted manually to suit the driving conditions
››› .
On level ground it is sufficient to move the
selector lever to position P. On slopes, first
engage the parking brake and then put the
selection lever into the P position. This
avoids overloading the locking mechanism
and it will be easier to move the selector lev-
er from position P. WARNING
Observe the safety warnings ››› in Selector
lever positions on page 133.
● Never allow the brake to rub and do not use
the brake pedal too often or for long periods.
