Changing bulbs
Gener a
l

notes Read the additional information carefully

 page 63
Changing bulbs requires a certain degree of
practical skill.
If you choose to change the engine compart-
ment lamps yourself, remember that it is a
dangerous area ››› in Safety notes for work
in the en gine c
omp

artment on page 273.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder. Depending on how equipped the vehicle is,
there are diff

erent sets of headlights and tail
lights:
● Halogen headlights.
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar bulb light
● LED rear light*
Ful
l-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the vehicle and the bulbs cannot
be replaced. In case of headlight failure, go
to an authorised workshop to have it re-
placed. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm, there is a risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. 106

Operation
If the engine does not start immediately,
sw it
c
h the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ››› page 104, Fuses. WARNING
● Never s t

art or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is
running.
● Never use “cold start sprays”, they could
explode or c
ause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metr
es to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in or
der to start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the
›››  page 71, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
engine w ith the

vehicle stationary. Start off
immediately, driving gently. This helps the
engine reach operating temperature faster
and reduces emissions. Starting diesel engines
The engine can only be started using a genu-
ine S
EA

T key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depre s

s the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to position ›››

Fig. 175
2 . The warning lamp
 wi
l l light for en-
gine pre-heating.
– When the lamp turns off, turn the ignition
key t

o position 3 to start the engine. Do
not pr
e
ss the accelerator.
– Release the ignition key as soon as the en-
gine star

ts. The starter motor should not
turn at the same time.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern. If there are problems starting the engine, see
the
›››

Glow plug system for diesel engines
To avoid unnecessary discharging of the bat-
tery, do not use any other major electrical
equipment while the glow plugs are pre-heat-
ing.
Start the engine as soon as the glow plug
warning lamp goes out.
Starting a diesel engine after the fuel tank
has run dry
If the fuel tank has been completely run dry,
it may take longer than normal (up to one mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first. WARNING
Observe the safety warnings ›››
in Starting
petro l
engines on page 174. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metr
es to start the engine. Un-
burnt fuel could enter the particulate filter
and damage it. 174

Driving
Take the vehicle to a specialised workshop
and h av
e the f
ault repaired without delay.
 Gearbox: System fault! You
can continue driving in D until
switching off the engine
Stop the vehicle in a safe place well away
from moving traffic. Seek specialist assis-
tance.  Gearbox: too hot. Adapt your
driving accordingly
Continue driving at moderate speeds. When
the warning lamp switches off, you can con-
tinue driving in a normal manner.  Gearbox: press the brake and
engage a gear again.
If the fault was caused by a gearbox with a
high temperature, this driver message will be
displayed when the gearbox has cooled
again.
Gear-change indicator
Selecting the optim
al gearWhile driving, and depending on vehicle
equipment, the in
s
trument

panel display may
show a recommendation with the gear num-
ber that would be advisable to save fuel. In vehicles with an
automatic gear
box, the
selector lever must be in the tiptronic posi-
tion ››› page 190.
No recommendation will appear if the opti-
mal gear is already engaged. The current
gear will be displayed.
DisplayMeaning 
The optimal gear is selected.
  
Changing to a higher gear is recom-
mended.
  

Information regarding the “cleanliness” of
the die
sel
p

articulate filter
The exhaust system manager detects that the
diesel particulate filter is nearly saturated
and contributes to self-cleaning by recom-
mending the optimal gear. For this reason, it
might be necessary to drive for a short time
at a high rpm. WARNING
The gear change indicator is only an auxiliary
fu nction and in no c

ase should be a substi-
tute for careful driving.
● The responsibility of choosing the correct
gear dependin
g on the situation (e.g. over-
taking, driving up or down a slope or towing a
trailer) lies with the driver. For the sake of the environment
Selecting the correct gear can help to save
fuel . Note
The recommended gear indication turns off
when the clut c

h pedal is pressed in vehicles
with manual gearbox or when the selector
lever is removed from the tiptronic position in
vehicles with an automatic gearbox. Steering
Intr oduction The power steering is not hydraulic but elec-
tr
omec
h

anical. The advantage of this steer-
ing is that it foes not need flexible hydraulic
pipes, hydraulic oil, pump, filter or other
parts. The electromechanical system saves
fuel. Whereas a hydraulic system needs con-
tinuous oil pressure, electromechanical
steering only needs power when it is used.
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running. »
