Diesel engines can take a few seconds longer
than usual to start on cold days. Therefore
the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must re-
main pressed until the engine starts up. Dur-
ing preheating, the warning lamp  remains
lit.
The preheating time depends on the coolant
and exterior temperatures. With the engine at operating temperature, or at outside temper-
ature

s above +8°C, the warning lamp  will
light up for about one second. This means
that the engine starts immediately.
If the engine does not immediately start up,
interrupt the starting process and try again
after 30 seconds. To start the engine again,
return the key to position ››› Fig. 191 1 .

Handbrake between the front seats.184

Driving
The handbrake should be applied firmly to
pr ev
ent
the vehicle from accidentally rolling
away.
Always apply the handbrake when you leave
your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly
›››
Fig. 196.
Releasing the handbrake
– Pull the lever up slightly and press the re-
lea

se knob in the direction of the arrow
››› Fig. 196 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.
If you drive faster than 6 km/h (4 mph) with
the handbrake on, the following message*
will appear on the instrument panel: HAND-
BRAKE ON. You will also hear an audible
warning. 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
ap

plied 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 vehic

le. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
p
lied 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.
– Never leave a vehicle key in the vehicle. Additional notes on parking the vehicle on
gradient

s:
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 vehicle 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. » 185

Operation
●
Dependin g on w
eather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Brakes
New brake pads
For the fir
s

t 400 km (250 miles), new brake
pads have not yet reached their maximum
braking capacity, and need to be “run in”
first. However, you can compensate for the
slightly reduced braking effect by applying
more pressure on the brake pedal. Avoid
overloading the brakes while running them
in.
Wear
The rate of wear on the brake pads depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is
a particular problem in urban traffic and
short stretches, or with very sporty driving.
Depending on the speed, the braking force
and the environmental conditions (for exam-
ple, the temperature, air humidity, etc.)
noises may be produced on braking.
Wet roads or road salt
In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac- tion could be delayed if the discs and pads
are d
amp

, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
At high speed and with the windscreen wip-
ers activated, the brake pads will briefly
touch the brake discs. This takes place, al-
though unnoticeable to the driver, at regular
intervals to improve the response time of the
brakes when they are wet.
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. The layer of salt that accumulates on the
discs and pads can be removed by gently ap-
plying the brakes a few times.
Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if
rust has formed on the disks, it is advisable
to clean off the pads and disks by braking
firmly a few times at a moderately high speed
››› .
F au
lt

in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two brake circuits has failed. Drive immediately
to the near

est specialised workshop and
have the fault repaired. Drive there slowly
and remember that you will have to apply
more pressure on the brake pedal and allow
for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● App ly

the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the en
gine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. 186

Operation
at a higher speed than the inner wheel. In
thi s
w
ay, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected.
Multi-collision Brake
In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the vehicle, as long as the accident has not dam-
aged the ESC, the br
ake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, EDL, el ectr

onic self-
locking differential or selective torque control
systems cannot exceed the limits imposed by
the laws of physics. Always bear this in mind,
especially on wet or slippery roads. If you no-
tice the systems cutting in, you should re-
duce your speed immediately to suit the road
and traffic conditions. Do not be encouraged
to take risks by the presence of more safety
systems. If you do, an accident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDL, electronic
self-locking and selective torque control sys-
tems cannot prevent accidents: risk of acci-
dents! ●
Ac c

elerate with caution on slippery surfa-
ces (for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i

ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can mak
e noises when they intervene.
● If the warning lamp  lights up
, or  alter-
natively, there could be a fault ››› page 119. Switching on/off the ESC and ASR
