Setting temperature– You can set the desired interior temperature after switching on the ignition with the
control dial .
You can set the interior temperature betw
een +18°C (64°F) and +29°C (86 °F). The
interior temperature is regulated automatica
lly within this range. If you select the
temperature below +18°C (64°F), “LO” appears in the display. If you select the temper-ature higher than +29°C (86°F), “HI” appears
in the display. In both limit positions the
Climatronic operates at ma
ximum cooling or heating capacity, respectively. The
temperature is not controlled in this case. Lengthy and uneven distribution
of the air flow out of the vents (in particular at the leg
area) and large differences in temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.Controlling blower There are a total of seven blower stages available.The Climatronic system controls the blower st
ages automatically in
line with the inte-
rior temperature. You can also, however, adap
t the blower stages manually to suit your
particular needs. – Turn the control dial
page 87, fig. 92
to the left (reduce blower speed) or right
(increase blower speed).
If you switch off the blower, th
e Climatronic is switched off.
WARNING
“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident increases.
Do not switch the Climatronic system off for longer than necessary.
Switch the Climatronic system on as soon as the windows mist up.

You should not switch on any major elec
trical components during the heating
period otherwise
the vehicle battery will
be drained unnecessarily.
- start engine Applies to all models: Position
To lock the steering
, with the ignition key withdrawn, turn the steering wheel until the
steering locking pin is heard to
engage. You should always lock the steering as a general
rule if you leave your vehicle. This acts as
a deterrent against possible theft of your
vehicle
.
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot easily be turned into this position, in order to release the steering lock. Position
The engine is started in this position. At th
e same time switched on low beam or main
beam or other electrical components wi
th major power consumption are briefly
switched off. The ignition key moves back into position when one releases the key. The ignition key must be turned back into
position each time before starting the
engine again. The starter repeat lock in th
e ignition lock prevents the starter being
engaged when the engine is r
unning and thus getting damaged.
WARNING
When driving, the ignition key must always be in the position (ignition
switched on) without the engine running. This position is indicated by the warning lights coming on. If this is not the case, it could result in unexpected locking of the steering wh
eel - risk of accident!
Do not withdraw the ignition key from the lock until the vehicle has come to
a stop. The steering lock can engage
immediately - risk of accident!
Always withdraw the ignition key if you are going to leave the vehicle, even
for a short time. This is particularly important if children are left in the vehicle. The children might otherwise start the en
gine or operate electrical equipment
(e.g. power windows) - risk of injury!
Starting the engineGeneral You can only start the engine only using an original ignition key.
Place the gearshift lever into neutral (or
place the selector lever to the position
P or
N in the case of an automatic gearbox) and put on the handbrake firmly before starting the engine.
The clutch pedal should be fully depressed when starting the engine - the starter
then only has to crank the engine.
Let go of the key as soon as the engine starts otherwise there may be damage to
the starter. The engine running noises may louder at first be louder for a short time after starting the cold engine until oil pressure can be
built up in the hydraulic valve clearance
compensation. This is quite normal and is not an operating problem. If the engine does not start ... You can use the battery of anothe
r vehicle as a jump-start aid
page 190.
It is only possible to tow-start vehicles fi
tted with a manual gearbox. The tow-starting
distance must not be more than 50 metres
page 193.
WARNING
Never run the engine in non ventilated
or enclosed areas. The exhaust gases
of the engine contain besides the odorless and colourless carbon monoxide a poisonous gas - hazard! Carbon mono
xide can cause unconsciousness and
death.
Never leave your vehicle unattended with the engine running.Caution
The starter may only be operated (ignitio
n key position ), if the engine is not
running. If the starter is imme
diately operated after switchin
g off the engine, the starter
or the engine can be damaged.

Technical Data
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper
ating temperature - risk of damaging the
engine!
Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away. When driving the engine reaches its operating te
mperature more rapidly and the pollutant
emissions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture for every external air temperature.
Do not operate accelerator before and when starting engine.
Interrupt the attempt at starting after 10
seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.
It is possible that the fuse on the electric
al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
page 195.
If the engine does not start, contact the nearest specialist garage to obtain profes-
sional assistance. It may be necessary, if the engine is
very hot
, to slightly depress the accelerator after
the engine has started.Diesel enginesGlow plug system Diesel engines are equipped with a glow
plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside tempera- ture. The preglow indicator light
comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating period otherwise the vehicle battery will be drained unnecessarily.
You should start the engine immediately after the glow plug warning light
has
gone out.
The glow plug warning light will come on for about one second if the engine is at a
normal operating temperature or if the outside temperature is above +5°C. This means that you can start the engine
right away
.
Interrupt the attempt at starting after 10 seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.
It is possible that the fuse
on the diesel preglow system is defect if the engine still
does not start. Check the fuse and replace it if necessary
page 195.
Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after fuel tank has run dry It may take longer than normal to start the
engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is
because the fuel system must first of all
be filled while the attempting to start the engine.Switching off the engine– The engine can be switched off by turnin
g the ignition key from position into
page 89, fig. 94
.
WARNING
Never switch off the engine before the ve
hicle is stationary - risk of accident!
The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en
gine is switched off.
Because if you do
not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey after the engine has been operated for a lengthy period
at high loads but should be allowed it
to run at idling speed for about 2 minutes.
This prevents any accumulation of heat
when the engine is switched off.

Note
The radiator fan may continue running fo
r a further 10 minutes or so after the
engine and the ignition have been switched
off. The coolant fan may, however, also
switch on again after some time if the co
olant temperature rises because of an accu-
mulation of heat in the engine or if the engine is warm and the engine compartment is additionally heated
by strong sunlight.
This is why particular care is required
when carrying out any work in the engine
compartment
page 166, “Working in the engine compartment”.
Shifting (manual gearbox)Shift into reverse only when the vehicle is
stationary. Depress the clutch pedal and hold
it fully depressed. Wait a moment before en
gaging reverse gear in order to avoid any
shift noises. The reversing light will come on once reverse gear is engaged, provided the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
One should not lay the hand on the shift lever while driving the vehicle. The pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over a period of time, lead to earl
y wear of the gearshift forks.
Depress the clutch pedal fully when changi
ng gears, in order to avoid unnecessary
wear and damage.HandbrakeApplying the handbrake– Pull the handbrake lever up fully.Releasing the handbrake– Pull the handbrake lever up slightly and

WARNING
If the engine is switched off, neit
her the brake booster nor the electrohy-
draulic power steering operates.
Never let the vehicle roll wi
th the engine switched off.
Caution
If the “START-STOP” system is used at very
high outside temperatures over a longer
period of time, the vehicl
e battery can be damaged.
Note
A change in ambient temperature can affect the temperature inside the battery
with several hours delay. For example, if
the vehicle is standing outside for a long
period of time at a temperature below freezi
ng, or vice versa under
direct sunlight, it
may take several hours until the temperat
ure inside the battery reaches the appro-
priate temperature for the START-STOP system.
In some cases, it is necessary to manually start the engine using the key (for
example, if the driver's seat belt is not fastened or if the driver door is open for a period of more than 30 seconds during the stop
phase). Pay attention to the relevant
messages in the instrument cluster.
If the Climatronic* is switched into the automatic mode, this may in certain circum-
stances prevent the automatic engine shut down.

Automatic gearbox
98Automatic gearboxAutomatic gearbox*Information for driving with the 6-speed automatic gearbox* Your car is equipped with a conv
entional 6-speed automatic gearbox.
The maximum speed is reached in the 5th gear. The 6th gear serves as an economic driving programme, which is intended to redu
ce the fuel consumption. Shifting up and
down through the gears is performed automa
tically. You can also, however, switch the
gearbox over into the
Tiptronic mode
. This mode makes it possible for you to also shift
gears manually
page 102.
Starting-off and Driving– Depress the brake pedal fully and keep it depressed. – Press the Shiftlock button (button in ha
ndle of the selector lever), move the
selector lever into the
desired position, e.g.
D page 99, and then release the
Shiftlock button.
– Wait a moment until the gearbox has shif
ted (a slight engage
ment nudge can be
felt).
– Release the brake pedal and depress the accelerator
.
Stop– The selector lever position
N does not have to be selected when stopping just for
a short time, such as at a cross roads. It
is sufficient to hold
the vehicle stationary
using the foot brake. The engine can, however, be allowed just to idle.
Parking– Depress the brake pedal and hold it depressed. – Apply the handbrake firmly.– Press and Shiftlock button in the selector lever, move the selector lever to
P and
then release the Shiftlock button.
The engine can only be
started
when the selector lever is in position
P or N page 90.
It is sufficient to engage selector lever position
P when parking on a flat surface. When
parking on a slope you should first apply
the handbrake firmly and then move the
selector lever into position
P. This is to ensure that there is no excessive pressure acting
on the lock mechanism and that it is easier to subsequently move the selector lever out of position
P.
If the selector lever position
N is selected by accident while driving it is first necessary
to release pressure on the accelerator pedal and wait for idling speed of the engine to be reached before engaging a driv
e position in the selector lever.
WARNING
Do not depress the accelerator when changing the position of the selector
lever if the car is stationary and the engine is running - risk of accident!
Never move the selector lever into position R or P when driving - risk of an
accident!
When the engine is running and the vehi
cle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (except P and N) since the power transmission is never completely interrupted, also not when the engine is idling - the vehicle creeps.Information for driving with the automatic gearbox DSG* The abbreviation DSG mean
s Direct shift gearbox (Direct shift gearbox).
Two independent clutches are needed for the power transmission between the engine and the gearbox. These replace the torque
converter of the conv
entional automatic
gearbox. Their shifting is matched in such
a way that there are no jerks when shifting
the gear and the power transmission of the engine to the front wheels is not inter- rupted. Shifting up and down through the
gears is performed automatically. You can
also, however, switch the gearbox over into the
Tiptronic mode
. This mode makes it
possible for you to also shift gears manually
page 102.
Starting-off and Driving– Depress the brake pedal fully and keep it depressed.
