Climatronic automatically maintains a com-
fortable temperature. To do so, it automati-
cally regulates the supplied air temperature
and the blower and air distribution levels.
The system also allows for the effect of sun-
light, so there is no need for manual adjust-
ment. It also has a humidity sensor that
helps to automatically demist the wind-
screen.

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
Observe the safety warnings ››› in Starting
petrol en
gines on page 151. CAUTION
● When the engine is c
old, 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 metre
s 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 order t
o start it, you should first try to
start it using the battery of another vehicle. Please observe and follow the notes on the

p
age 52, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
en gine with the v
ehicle stationary. You
should drive off as soon as you start the en-
gine. This helps the engine reach operating
temperature faster and reduces emissions. Switching off the engine

ching 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 swit c
h the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is runnin
g. With the engine switched off,
more strength is needed to brake. As normal brake operation cannot be performed, risk of
accident
s
and serious injury may exist.
● The steering lock can be immediately
blocked onc
e the key is removed from the ig-
nition. The vehicle cannot be steered. Risk of
accident.
● Power-assisted steering does not work
when the engine is off
, and more strength is
needed to turn the wheel.
● If the key is removed from the ignition lock
the steering loc
k could be engaged and vehi-
cle steering would not work. CAUTION
When the engine has been running under a
heavy lo a

Operation
Applying the handbrake
– Pull the handbrake lever up firmly
› ›
›
Fig. 169
.
Releasing the handbrake
– Pull the lever up slightly and press the re-
lease kno
b in the direction of the arrow
››› Fig. 169 and guide the handbrake lever
down fully ››› .
A lw
ay
s pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The h andbr
ake w
arning 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 h andbr
ake 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 wi
ll 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 vehic l
e. Put it in 1st gear as well. In vehi-
cles with an automatic gearbox, place the
gear lever in position P. Parking
The handbrake should always be firmly ap-
plied when the v
ehic
le 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. T urn the s
teering wheel
slightly to engage the steering lock.
– Always take you keys with you when you
leave the
vehicle ››› .
Ad dition
al
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 vehic
le is parked facing uphill, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrake firm
ly and putting it in 1st gear. WARNING
● Take me a
sures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
could ignit
e inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehicl
e 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 coul
d 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. 154
Operation
At speeds of up to approximately 80 km/h
(50 mph), it i
s ab
le to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally
without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down.
Control lamp
A malfunction in the EDL is indicated by the
ABS control lamp ››› page 158. Take the
vehicle to a specialised workshop as soon as
possible. WARNING
● When accel er
ating on a slippery surface,
for example on ice and snow, press the accel-
erator carefully. Despite EDL, the driven
wheels may start to spin. This could impair
the vehicle's stability.
● Always adapt your driving style to suit road
conditions and the tr
affic situation. Do not let
the extra safety afforded by EDL tempt you in- to taking any risks when driving, this can
cause ac
c
idents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the br ake sys
tem, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 190. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
on
ly
inc luded in
vehicles with ESC.
In an emergency, most drivers brake in time,
but not with maximum force. This results in
unnecessarily long braking distances.
This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake. Automatic hazard warning lights activation
The brake lights fl
ash automatically to indi-
cate that the vehicle is braking suddenly or in
an emergency situation. If the emergency
braking continues until the vehicle comes to
a standstill, the hazard warning lights will
then come on and the brake lights will re-
main on permanently from that moment. The
warning lights will automatically switch off
when the vehicle begins to move again or
when the "warning" light button is pressed. WARNING
● The risk of ac
cident is higher if you drive
too fast, if you do not keep your distance from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist system.
● The brake assist system cannot defy the
laws
of physics. Slippery and wet roads are
dangerous even with the brake assist system!
Therefore, it is essential that you adjust your
speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you
into taking any risks when driving. Anti-lock brake system (ABS)
The anti-lock brake (ABS) system prevents
the wheel
s
fr om loc
king during braking and
is an important part of the vehicle's active
safety system.

Operation
Selecting the normal programme
– Put the selector lever into position D.
Sel ectin
g the s por
t programme
– Put the selector lever into position S.
If you sel
ect the normal programme, D, you
will drive in the economy mode, i.e. the pro-
gramme is designed to reduce fuel consump-
tion. The gearbox changes up into a higher
gear as soon as possible and down into a
lower gear as late as possible.
If you select the sport programme, S, you will
drive in a sporty mode, i.e. a programme in
which shifts into high gears are postponed in
order to use the full power of the engine.

Selector lever positions
The selected gear is displayed on the side of
the selector lever and on the instrument pan-
el display. The currently selected gear for the
automatic gearbox will also be shown on the
display. Tiptronic gear indicator
If the automatic
gearbox is shifted manually,
the selected gears are shown on the screen.
P - parking lock
When the selector lever is in this position,
the driven wheels are locked mechanically.
Position P on the lever must only be selected
if the vehicle is stationary.
To move selector lever from position P, the
locking button on the selector lever handle
must be pressed and the brake pedal de-
pressed at the same time while the ignition is
switched on.
To put the selector lever in position P, simply
press the lock button down and, if necessary,
depress the brake pedal down.
R - Reverse gear
The reverse gear is engaged in this position.
Reverse gear must be engaged only when the
vehicle is stationary and the engine is idling.
To move the selector lever to position R,
press the lock button down and, at the same
time, press the brake pedal down, with the
ignition switched on.
With the selector lever in position R and the
ignition switched on the following occurs:
● Reverse lights light up. ●
The air conditioner automatic ally changes
the air recirculation mode.
● The wiper starts if the windscreen washer is
on.
● The parking distance warning system*
switche
s on.
N - Neutral (idling)
If this position is selected, the gearbox is in
neutral. Power is not transmitted to the
wheels and the engine does not have a brak-
ing function.
Never use the N position to drive down a long
hill. There is no engine braking and the
brakes are subjected to excessive stain.
You could damage the automatic gearbox if
you drive down hills with the gearbox lever in
position N and the engine switched off.
D - Drive (forward)
In this position the gearbox automatically
changes to a lower or higher gear, according
to the engine's requirements, the driving
style and speed. The braking effect of the en-
gine when driving downhill is very limited
when the selector is in this position. The in-
strument panel display shows the selected
gear as well as the selector lever in position
D.
When travelling at speeds lower than 5 km/h
(3 mph) or when the vehicle is stationary,

pedal is not depressed.
The ignition key cannot be removed unless
the selector lever is in position P.
Control lamp “Pressing brake pedal”
When the warning lamp next to the selector
lever lights up, press the brake pedal. This is
necessary when the automatic gearbox selec-
tor lever is moved out of positions P or N. A
text message or instructions to perform nec-
essary operations may appear on the instru-
ment panel. CAUTION
● If y ou s
top 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 ru
nning, or with the selector lever
in position N, a lack of lubrication in the auto-
matic gearbox will damage it. Kick-down feature
This feature allows maximum acceleration. If you press the accelerator down thoroughly,
the g
e
arbo x
automatically changes down, de-
pending on speed and engine speed, into a
lower gear to take full advantage of give the
vehicle maximum acceleration.
The gearbox does not change gear until the
engine reaches the maximum determined en-
gine speed for the gear. WARNING
You could lose control of the vehicle if you ac-
celer at
e on slippery road surfaces. Risk of se-
rious injury.
● Be particularly careful when using the kick-
down feat
ures on slippery road surfaces. With
a fast acceleration, the vehicle could lose
traction and skid.
● You should use the kick-down feature only
when traffic and we
ather conditions allow it
to be used safely. Gearbox malfunctions

Operation
Catalytic converter To maintain the useful life of the catalytic
conv
er
ter
– Use only unleaded petrol with petrol en-
gines, as l
ead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too much en
gine oil ››› page 206, Top-
ping up engine oil.
– Never tow the vehicle to start it, use jump
lea d
s if necessary ›››
page 52.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 100. If this hap-
pens, unburnt fuel can enter the exhaust sys-
tem and escape into the environment. The
catalytic converter can also be damaged by
overheating. CAUTION
Never run the fuel tank completely dry be-
cause the irr e
gularity 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
workin g per
fectly, 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. 173
Vehicle data sticker on back cover of

e Programme. Your vehicle is fitted with a DPF (Diesel Partic-
u
l
at e Fi
lter) if the vehicle data sticker (back
cover of the “Maintenance Programme”) lists
the code PR 7GG ››› Fig. 173.
The diesel 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
obstruct
ed 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
below.
Accumulation of soot in the diesel engine
particulate filter*
If the control lamp lights up you should
help the filter clean itself by driving in the ap-
propriate manner.
To do this, drive about 15 minutes in fourth
or fifth gear (automatic gearbox: S gear
range) at a minimum speed of 60 km/h
(37 mph), with the engine running at approxi-
mately 2,000 rpm. In this way, the soot build
up in the filter is burned. When cleaning is
successful, the control lamp turns off.
If the lamp does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
Always drive according to the road weather
conditions, the t err
ain and traffic. Driving rec-
ommendations should never lead to illegal
manoeuvres in surrounding traffic. 170
