Engine management* This warning lamp monitors the engine man-
agement system for petrol engines.
The warning lamp (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Stop the vehi-
cle and seek technical assistance.
Glow plug system/Engine fault* The warning lamp lights up to show that the
glow plugs are preheating the diesel engine.
The control lamp
lights up
If the control lamp lights up when the en-
gine is started it means that the glow plugs
are preheating. When the warning lamp goes
off, the engine should be started straight
away.

Note
When towing the vehicle with the engine
stopped or due to a fault in the power steer-
ing, this will not operate. The vehicle can still
be steered, but it will require greater force to
turn the steering wheel. Emission control system*
Control lamp
flashes:
When ther e i
s misfiring that can damage the
catalytic converter. Reduce speed and drive
carefully to the nearest specialised workshop
to have the engine checked.
The control lamp lights up:
If a fault has developed during driving which
has reduced the quality of the exhaust gas
(e.g. lambda probe fault). Reduce speed and
drive carefully to the nearest specialised
workshop to have the engine checked.
Level*/Temperature of the coolant There is a fault if:
● The warning symbol does not go out again
after a few seconds.
● The warning lamp lights up or flashes while
the vehicle is moving, and three acoustic
warning signals ›
›
› are emitted.This means that either the coolant level is too
low or the coolant temperature is too high.
Coolant temperature too high
If the warning lamp comes on,
stop the vehi-
cle, turn off the engine and wait for it to cool
down. Check the coolant level.
If the c
oolant level is correct, the overheating
may be caused by a malfunction of the radia-
tor fan. Check the radiator fan fuse and have
it replaced if necessary ››› page 195.
If the control lamp lights up again after driv-
ing on for a short distance, stop the vehicle
and switch the engine off
. Contact a Techni-
cal Service or a specialised workshop.
Coolant level too low
If the warning lamp comes on , stop the vehi-
cle, turn off the engine and wait for it to cool
down
. First check the coolant level. If the lev-
el of the coolant is below the “MIN” mark,
top up with coolant liquid ››› .
WARNING
● If your vehicle is immobilised for technical
reasons, move it to a safe distance from traf-
fic. Turn the engine off, turn the hazard lights
on and place the warning triangle.
● Never open the bonnet if you can see or
hear steam or coolant escaping from the en-
gine compartment. Risk of scalding. Wait un- til you can no longer see or hear escaping
steam or coolant.
●
The engine compartment is a dangerous
area. Before carrying out any work in the en-
gine compartment, switch off the engine and
allow it to cool down. Always note the corre-
sponding warnings ››› page 166. Alternator
This warning lamp signals a fault in the alter-
nator.
The warning lamp lights up when the igni-
tion is switched on. It should go out when the
engine has started running.
If the warning lamp
lights up while driv-
ing, the alternator is no longer charging the
battery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment
that is not absolutely necessary because this
will drain the battery.
Turn signals Depending on which turn signal is operating,
either the left
or right turn signal lamp
flashes. Both control lamps will flash at the
same time when the hazard warning lights
are switched on. »

Operation
Coolant system
When the air conditioning is switched on, the
temperature and the air humidity go down.
This way, if the outside humidity is extreme,
the air conditioning prevents the misting of
the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this
may be due to the following reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● The air conditioning system compressor
has been temporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning checked by a specialised work-
shop.
Air recirculation Air recirculation mode on
›››
Fig. 129 (a
lamp lights up on the button) prevents strong
odours or contaminated air from the outside air from entering in the vehicle, for example
when passing through a tunnel or in a traffic
jam.
When the outside temperature is low, air re-
circulation mode improves heating perform-
ance by heating air from the interior instead
of cold air from the outside.
When the outside temperature is high, air re-
circulation mode improves cooling perform-
ance by cooling air from the interior instead
of warm air from outside.
For safety reasons, the air recirculation
should not be switched on
when the air dis-
tribution control is set to the windscreen set-
ting . WARNING
In air recirculation mode, no cold air from the
outside enters the vehicle interior. If the air
conditioner is switched off, the windows can
quickly mist over. Therefore, never leave the
air recirculation mode switched on for a long
time (risk of accident). Note
● When engaging reverse gear, the air recir-
culation is connected automatically to pre-
vent the entrance of exhaust gases in the ve-
hicle on travelling backwards. The control
lamp on the button does not light up.
● If the temperature control is turned to the
coldest setting (blue point) and the A/C but- ton is on, the “Air recirculation” function is
automatically activated in order to cool the
vehicle faster using less energy, and its func-
tion control lamp will light up.
● If the function is not deactivated by press-
ing the button, it will deactivate after approx-
imately 20 minutes. Economic use of the air conditioning
When the air conditioning is switched on, the
compressor consumes engine power and has
influence on fuel consumption. Consider the
following points in order to have the system
operating in the minimum possible time.
● If the vehicle interior has overheated due to
an excessive solar radiation, it is best to
open the windows or doors to allow the hot
air to escape.
● While in motion, the air conditioning
should not be switched on if the windows or
the sunroof* are open.

Operation
CAUTION
When the engine has been running under a
heavy load for a long period, heat can accu-
mulate in the engine compartment and cause
engine damage. For this reason, idle the en-
gine for approximately 2 minutes before
switching it off. Braking and parking
Braking capacity and braking distance The efficiency of the brakes depends directly
on the
brake pad
wear. This wear depends to
a gr
eat extent on the conditions under which
the vehicle is operated and the way the vehi-
cle is driven. If you often drive in town, drive
short distances or have a sporty driving style,
we recommend that you have the thickness
of your brake pads checked by technical serv-
ices more frequently than recommended in
the Maintenance Programme.
If you drive with wet brakes, for example, af-
ter crossing areas of water, on days of heavy
rainfall or even after washing the car, the ef-
fect of the brakes is reduced as the brake
discs are wet or even frozen (in winter): in
this case, the brakes should be “dried” by
pressing the brake pedal several times. WARNING
Longer braking distances and faults in the
brake system increase the risk of accidents.
● New brake pads must be run in and do not
have the correct friction during the first
200 km. This reduced braking capacity may
be compensated for by pressing on the brake
pedal a little harder, which also applies when
the brake pads have to be changed further
on.
● If brakes are wet or frozen, or if you are
driving on roads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they will overheat. Before driving down
a long steep slope, it is advisable to reduce
speed and change down into a lower gear or
range (depending on the type of transmis-
sion). Thus, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pressure. Continuous braking will cause
the brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switched off. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subjected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. ●
Non-standard or damaged front spoilers
could restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 155, Technical modifica-
tions.
● If a br
ake system circuit fails, the braking
distance will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. Handbrake
Fig. 132
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.
126
Driving
Applying the handbrake
– Pull the handbrake lever up firmly
››› Fig. 132 .
R el
easing the handbrake
– Pull the lever up slightly and press the re-
lease knob in the direction of the arrow
››› Fig. 132 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. 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.
– Always take you keys with you when you
leave 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
.
● 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. Hill driving assistant*

Driving
WARNING
● As a driver, you should never leave your ve-
hicle if the engine is running and a gear range
is engaged. If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and put the selector lever
in position P.
● If the engine is running and if D or R is en-
gaged, you will need to hold the car on the
foot brake. The car will creep forward as the
power transmission is not fully interrupted
even when the engine is idling.
● Never accelerate when moving the selector
lever or you may cause an accident.
● Never move the selector lever to R or P
when driving. Risk of accident!
● Before driving down a long, steep slope, it
is advisable to reduce speed and change into
a lower gear.
● If you stop the vehicle up hill, always hold
the foot brake strongly depressed down to
stop it from rolling back.
● Never allow the brake to rub and do not use
the brake pedal too often or for long periods.
Constant braking will cause the brakes to
overheat and will considerably reduce the
brake effect. This increases the braking dis-
tance and could cause the brake system to
fail.
● Never allow the car to roll down a gradient
with the gear in neutral N, or in selector lever
position D, even if the engine is not running. CAUTION
● If you stop the vehicle up hills, do not at-
tempt to stop it from rolling back by depress-
ing the accelerator when a gear has been se-
lected. Otherwise, the automatic gearbox
may overheat causing damage. Pull the hand-
brake up or fully depress the brake pedal to
prevent the vehicle from rolling away.
● If you allow the vehicle to roll when the en-
gine is not running, or with the selector lever
in position N, a lack of lubrication in the auto-
matic gearbox will damage it. Changing gear in tiptronic mode*

The essentials
Operation
●
Do not apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. These materials could catch
fire when the vehicle is being driven. CAUTION
Never run the fuel tank completely dry be-
cause the irregularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel engine particulate filter*
Fig. 139
Vehicle data sticker on back cover of
the Maintenance Programme. Your vehicle is fitted with a DPF (Diesel partic-
ulate filter) if the vehicle data sticker (back
cover of the “Maintenance Programme)” lists
the PR code 7GG or 7MG
››› Fig. 139 .
The die sel
engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex-
ample, multiple short trips) the filter will be
obstructed by soot and the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you
must perform a cleaning cycle, as indicated
in ››› page 59
. WARNING
● The diesel engine particulate filter may
reach extremely high temperatures; the vehi-
cle should be parked so that the exhaust pipe
does not come into contact with flammable
materials underneath the vehicle. Otherwise
there is a risk of fire. CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-
tent may significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and wear to the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
