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-
prox
imately +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 c
hecked by a specialised work-
shop. Air recirculation
Air recirculation prevents unpleasant smells,
e.g. when p
a
ssing through a tunnel or in
queuing traffic, from entering the interior.
If the rotary switch C

Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-
hicle is stationary.
Activating the steering lock
● Park the vehicle ›››
page 156.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steerin

●
Turn the steering wheel slightly to release
the lock.
● Inser

Electromechanical steering
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.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, help s
the driver to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. Starting and stopping the en-

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 52, 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 reduc
e
s emissions. Starting diesel engines
The engine can only be started using a genu-
ine S

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.

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 been completely 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

itching the engine off, the radiator
fan may run on for up to 10 minutes. 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 expo-
sure to solar radiation. WARNING
● Never sw it
ch the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is ru

engine damage. For this reason, idle the en-
gine for approximately 2 minutes before
switching it off. Braking and parking
Br ak
in
g capacity and braking distance The efficiency of the brakes depends directly
on the br
ak
e p
ad wear. This wear depends to
a great 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
brak e sy
stem increase the risk of accidents.
● New brake pads must be run in and do not
have the c
orrect 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 r
oads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they w
ill 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 pre
ssure. Continuous braking will cause156

The reverse gear can only be engaged when
the car is stationary. When the engine is run-
ning and before engaging this gear, wait
about 6 seconds with the clutch pressed
down thoroughly in order to protect the gear-
box.
The reverse lights switch on when the reverse
gear is selected and the ignition is on. WARNING
● When the engine i s

● Do not r e
st your hand on the gear lever
while driving. The pressure of your hand
could cause premature wear on the selector
forks in the gearbox. ●
When ch an

depress the clutch fully to avoid unnecessary
wear and damage.
● Do not “slip” the clutch to hold the vehicle

The selector lever lock is released as follows: – Switch the ignition on.
– Press and hold the brake pedal and press
the sel ect
or l
ever lock on the left of the se-
lector lever at the same time ››› Fig. 170.
The warning lamp on the instrument panel
lights up when the brake pedal should be ap-
plied. This is essential when the selector lev-
er is taken from the P or N positions.
Level lock only engages with the vehicle sta-
tionary at a speed of up to 5 km/h (3 mph).
At speeds of over 5 km/h (3 mph) the selec-
tor lever lock is automatically deactivated in
position N.
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
in snow or mud. The selector lever lock en-
gages automatically if the brake pedal is not
depressed and the lever is in position N for
more than about 1second. Selecting gears manually with Tip-

General information about driving in tiptron-
ic mode
When accelerating, the automatic gearbox /
DSG automatic gearbox goes into a higher
gear a little before the engine reaches its
maximum permitted revolutions.
If a lower gear is selected, the automatic
gearbox / DSG automatic gearbox will only
change down when the engine cannot go
over its maximum permitted revolutions.

Stopping briefly – If stopping for a short time, keep the vehi-
cle s
tationary by pressing the foot brake
hard to prevent the vehicle moving back-
wards on a slope or “creeping” forwards,
e.g. at traffic lights. The selector lever does

– Apply the handbrake.
– With a selected gear, accelerate slowly and
at the same time, r
elease the handbrake.
The steeper the slope, the lower the needed
gear. This increases the braking effect of the
engine. For example, when driving down a
very steep slope in third gear. If the engine
brake effect is not enough, the vehicle will
speed up. The automatic gearbox automati-
cally changes up to prevent the engine over-
revving. Use the foot brake to reduce speed
