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
petro l
engines on page 148. 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
en gine w ith the
vehicle 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

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
nning. With the engine switched off,
more strength is needed to brake. As normal brake operation cannot be performed, risk of
acc

● The steering lock can be immediately
block
ed once 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 steerin

Releasing the handbrake
– Pull the lever up slightly and press the re-
lea
se knob in the direction of the arrow
››› Fig. 157 and guide the handbrake lever
down fully ››› .
A lw
a
ys pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The h andbr
ak
e 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 u se the h
andbrake 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 w
ill 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 v ehic
le. 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
ehicle 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 steering wheel
slightly to engage the steering lock.
– Always take you keys with you when you
leav
e the vehicle ››› .
Ad dition
a
l 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 downhil
l,
turn the front wheels so that they point to-
wards the kerb . ●
If the v
ehicle is parked facing uphill, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
handbrak
e firmly and putting it in 1st gear. WARNING
● Tak e me
asures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
coul
d ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehic
le 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 cou
ld set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever.
● Depending on weather conditions, it may
become extr
emely hot or cold inside the vehi-
cle. This can be fatal. 151

Driving
At speeds of up to approximately 80 km/h
(50 mph), it i
s
able 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 155. Take the
vehicle to a specialised workshop as soon as
possible. WARNING
● When acc el
erating 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 traffic situation. Do not let
the extra safety afforded by EDL tempt you in- to taking any risks when driving, this can
cau
se ac
cidents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the br ake sy
stem, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 187. 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
flash 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
accident 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
law
s 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 locking during braking and
is an important part of the vehicle's active

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,
pres
s 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 automatically changes

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. »1)

Driving
Starting the vehicle up hills
– Apply the handbrake.
– With a selected gear, accelerate slowly and
at the s
ame 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
and change into 3rd gear using Tiptronic*
››› in Selector lever positions on page 160.
Y our
v
ehicle has an automatic interlock
which prevents the selector lever from being
put into a position for driving forwards or in
reverse from positions P or N if the brake
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 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. Kick-down feature
This feature allows maximum acceleration.
If
y
ou press the accelerator down thoroughly,
the gearbox 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-

ulate 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
