2011 Seat Leon 5D warning light

40Airbag system
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag. 
Safety notes on the operation of the side airbag system
If airbags are used correctly, they can considerably reduce
the risk of injury in side impact collisions.
WARNING
● If you do not wear a seat belt, if you lean forward, or are not seated
correctly while the vehicle is in motion, you are at a greater risk of injury
if the side airbag system is triggered in an accident.
● In order for the side airbags to provide their maximum protection, the
prescribed sitting position must always be maintained with seat belts
fastened while travelling.
● Occupants of the outer seats must never carry any objects or pets in
the deployment space between them and the airbags, or allow children
or other passengers to travel in this position. It is also important not to
attach any accessories (such as cup holders) to the doors. This would im-
pair the protection offered by the side airbags.
● The built-in coat hooks should be used only for lightweight clothing.
Do not leave any heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks, must not be exerted upon
the backrest bolster because the system may be damaged. In this case,
the side airbags would not be triggered.
WARNING (Continued)
● Under no circumstances should protective covers be fitted over seats
with side airbags unless the covers have been approved for use in your
vehicle. Because the airbag is triggered from the side of the backrest, the
use of non-approved seat covers would obstruct the side airbag, serious-
ly reducing the airbag's effectiveness ⇒ page 208, Accessories, parts re-
placement and modifications.
● Any damage to the original seat upholstery or around the seams of
the side airbag units must be repaired immediately by a specialised
workshop.
● The airbags provide protection for just one accident; replace them
once they have deployed.
● When children assume an incorrect sitting position, they expose
themselves to an increased risk of injury in the event of an accident. This
is particularly the case if the child is travelling on the front passenger
seat and the airbag system is triggered in an accident; this could have
critical consequences including serious injury or death ⇒ page 46,
Child safety.
● Any work on the side airbag system or removal and installation of the
airbag components for other repairs (such as removal of the front seat)
should only be performed by a specialised workshop. Otherwise, faults
may occur during the airbag system operation.
● Do not attempt to modify components of the airbag system in any
way.
● The side and head airbags are managed through sensors located in
the interior of the front doors. To ensure the correct functioning of the
side and head airbags neither the doors nor the door panels should be
modified in any way (e.g. fitting loudspeakers). If the front door is dam-
aged, the airbag system may not work correctly. All work carried out on
the front door must be made in a specialised workshop.

not been expressly approved for use in your vehicle may not be attached
to the side windows ⇒ page 208, Accessories, parts replacement and
modifications.
● The built-in coat hooks should be used only for lightweight clothing.
Do not leave any heavy or sharp-edged objects in the pockets. Please, do
not hang the clothes on coat hangers.
● The airbags provide protection for just one accident; replace them
once they have deployed.
● Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lin-
ing) should only be performed by a specialised workshop. Otherwise,
faults may occur during the airbag system operation.
● Do not attempt to modify components of the airbag system in any
way.
● The side and head airbags are managed through sensors located in
the interior of the front doors. To ensure the correct functioning of the

⇒ fig. 34.
Needle in normal zone B
In normal driving conditions, the needle should be in the middle section of

Needle in warning zone C
The warning lamp* ⇒ fig. 48 2 will light up if the needle is in the warning
zone. The following warning message appears on the instrument panel dis-
play 1)
. Stop the vehicle and switch off the engine. Check the coolant level
⇒ page 224 ⇒ 
.
Even if the coolant level is correct do not continue driving. You should ob-
tain technical assistance.
WARNING
When working in the engine compartment, always observe the safety
warnings ⇒ page 217.
CAUTION
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. 
Rev counter
The rev counter displays the engine speed in revolutions per
minute. The start of the red zone ⇒ fig. 32 4
indicates the maximum engine speed
operating at service temperature. However, it is advisable to change up a in-
to a higher gear, move the selector lever to D or lift your foot off the acceler-
ator before the needle reaches the red zone.
CAUTION
The rev counter needle must never enter the red zone on the scale. Risk of
engine damage.
For the sake of the environment
Changing up into higher gears sooner, following the recommended gear in-
dications ⇒ fig. 38 will help you to reduce fuel consumption, emissions and
also engine noise. 
Speedometer
The speedometer is equipped with a digital odometer and a trip recorder, in
addition to a service intervals display.
During the running-in period, the instructions shown on ⇒ page 189
should be followed. 
Setting the digital clock*
The digital clock is located in the instrument panel display.
– Turn the setting knob ⇒ fig. 32 5

The speed may be altered using the rocker switch B
in steps of 5 km/h
within 5 seconds of the initial memory value.
WARNING
There could be black ice on the road surface even if the “snowflake sym-
bol” is not shown. For this reason you should not rely exclusively on this
display - Risk of accident!
Note
When the vehicle is stationary or travelling at very low speeds, the tempera-
ture displayed may be slightly higher than the actual outside temperature
as a result of the heat radiated from the engine. 
Warning or information message in the display
Faults are shown in the display with warning lamps and
warning/information reports.
The system runs a check on certain components and functions when the ig-
nition is switched on and while the vehicle is moving. Functional faults are
indicated by symbols with warning or information messages in the display.
An acoustic warning is given in certain cases.
Warning symbols
There are red warning symbols (priority 1) and yellow warning symbols (pri-
ority 2)
Information text
In addition to warning messages given on a fault, you will receive informa-
tion in the display on procedures or will be asked to carry out certain tasks.
Note
In the case of screens without warning or information texts, faults are indi-
cated exclusively by the warning lamps. 
Warning reports, Priority 1 (red)
If one of these faults occurs, the warning lamp will flash or light up and will
be accompanied by three audible warnings. This is a danger warning. Stop
the vehicle and switch off the engine. Check the fault and correct it. Obtain
professional assistance if necessary.
If several priority 1 faults are detected at the same time, the symbols will be
displayed one after the other for about 2 seconds at a time and will contin-
ue until the fault is corrected.
No menus will be shown in the display for the duration of a priority 1 warn-
ing message.
Examples of priority 1 warning messages (red)
● Brake system symbol  with the warning message STOP BRAKE FLUID
SERVICE MANUAL or STOP BRAKE FAULT SERVICE MANUAL .
● Coolant symbol  with the warning message STOP SEE COOLANT IN-
STRUCTION MANUAL.
● Engine oil pressure symbol  with the warning message STOP ENGINE
OIL PRESSURE LOW! INSTRUCTION MANUAL . 
Warning reports, Priority 2 (yellow)
If one of these faults occurs, the warning lamp lights up, and is accompa-
nied by one audible warning. The function should be checked as soon as
possible. 
