g the handbrake Fig. 186
Handbrake between the front seats. 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. 186. Releasing the handbrake
– Pull the lever up slightly and press the re-
lea

se knob in the direction of the arrow
››› Fig. 186 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 display: HANDBRAKE ON. You will also hear an audi-
ble 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 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. 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.
– Never leave a vehicle key in the vehicle.
Additiona
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 vehicle is parked facing uphill
, turn
the front wheels so that they point away from
the kerb.

Operation
Exhaust gas filtration systems Catalytic converter
App
lie
s to vehicles with petrol engine: the
vehicle must only be used with unleaded pet-
rol, otherwise the catalytic converter will be
irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: 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. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h in 4th or 5th gear (auto- matic gearbox: gear S). Maintain the engine
speed at
ap

proximately 2,000 rpm. The rise
in temperature causes the soot on the filter
to burn. On completion of the cleaning the
warning lamp will switch off. If the warning
lamp does not switch off, go immediately to a
specialised workshop to rectify the problem. WARNING
● Bec au

se of the high temperatures which
can occur in the exhaust gas control system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the ar
ea of the exhaust system: Fire
hazard! Driving through flooded roads
To prevent damage to the vehicle when driv-
in
g thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edg
e of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc ., the br

aking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, running gear or electrical
system.
● Whenever driving through water, the Start-
Stop sys
tem* must be switched off
››› page 183. Note
● Check the depth of

the water before enter-
ing the flooded zone.
● Do not stop in the water, drive in reverse, or
stop the en
gine in any situation.
● Note that vehicles travelling in the opposite
direction ma
y splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). 176

Driver assistance systems
The control lamp  swit
c hes off. For vehicles
with a driver information system* the driver
will be informed that ASR is enabled.
Disconnection of the ESC
In some versions of the model, besides the
traction control system (ASR), the electronic
stability programme (ESC) can also be
switched off. ● Press the button  ›››
Fig. 190 for approxi-
mately 1 second to switch off the ASR func-
tion.
● Press the button  ›››
Fig. 190 for approxi-
mately 3 seconds to switch off the Electronic
Stability programme (ESC), including the ASR
function.
● The ASR and ESC function are reconnected
by pr
essing the button  ››› Fig. 190.
● OR: activate or deactivate the ASR or ESC
fu
nction in the Easy Connect system by
means of the button  and the function
b utt
on

s Setup and
E
SC
System .
WARNING
You should switch on the ESC Sport mode on-
ly if the tr

affic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
● With ESC in Sport mode, the stabilising
function w
ill be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could “skid”. ●
If the E SC/ASR i

s deactivated, the vehicle
stabilisation function is not available. Note
If the ASR is disconnected or the ESC’s Sport
mode i s sel

ected, cruise control* will be
switched off. Brakes
New brake pads
F
or 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 cert

ain 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 damp, 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
