Operation
Stability programme (ESC), including the ASR
function.
●
The ASR and ESC function are reconnected
by pressing the button
›
›› Fig. 146
.
●
OR: activate or deactivate the ASR or ESC
function in the Easy Connect system by
means of the button
and the function
buttons
Setup
and
ESC System
.
WARNING
You should switch on the ESC Sport mode on-
ly if the traffic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
●
With ESC in Sport mode, the stabilising
function will be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could skid.
●
If the ESC/ASR is deactivated, the vehicle
stabilisation function is not available.
Note
If the ASR is disconnected or the ESC’s Sport
mode is selected, cruise control* will be
switched off.
Brakes
New brake pads
For the first 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 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
››› .
Fault in the brake system
If the brake pedal travel should ever increase
suddenly
, this may mean that one of the two
br
ak
e circuits has failed. Drive immediately
to the nearest 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.
