DRIVING HINTS
Driving precautions
▷ With petrol engines, 4500 rpm and 160 km/h,
100 mph.
Vehicle equipment
▷ With diesel engines, 3500 rpm and 150 km/h,
93 mph.
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment which is not installed in your vehicle, for ex‐
ample on account of the optional equipment se‐
lected or the country variant. This also applies to
safety-relevant functions and systems. Please
comply with the relevant laws and regulations
when using the corresponding functions and
systems.
Generally avoid kick-down and driving under full
load.
From 2000 km, 1200 miles onwards
Engine and road speeds can be gradually in‐
creased.
Tyres
Due to the manufacturing process, new tyres do
not achieve their full road grip immediately.
Running in
Drive moderately for the first 300 km, 200 miles.
General
Moving parts need to adjust to each other.
Brake system
Brake discs and pads only achieve their full ef‐
fectiveness after approximately 500 km,
300 miles. Drive moderately during this running-
in period.
The following notes will help to maximise the ve‐
hicle's lifetime and efficiency.
Do not use Launch Control when running in.
Safety note
Clutch
The clutch only begins to function optimally at
approximately 500 km, 300 miles. Engage the
clutch gently during this running-in period.
WARNING
New parts and components can cause safety
and Driver Assistance Systems to respond with
a delay. There is a risk of accident. After new
parts have been installed or if the vehicle is
new, drive moderately and intervene in good
time if necessary. Please comply with running-
in procedures for the corresponding parts and
components.
After fitting new parts
The same running-in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Engine, gearbox and differential
Up to 2000 km, 1200 miles

Exhaust gas particle filter
General driving information
Principle
Closing the boot lid
Safety note
The exhaust gas particle filter collects soot parti‐
cles. The soot particles are burned at high tem‐
peratures to clean the exhaust gas particle filter
as necessary.
WARNING
General
When open, the boot lid protrudes above the
vehicle, and in the event of an accident, braking
or evasive manoeuvres, it can endanger vehicle
occupants and other road users, or damage the
vehicle. There is also a danger of exhaust
fumes entering the interior of the vehicle. There
is a danger of injury or damage to property. Do
not drive with the boot lid open.
The cleaning process takes a few minutes, dur‐
ing which the following may occur:
▷ The engine may temporarily run a little
roughly.
▷ A slightly higher engine speed may be re‐
quired to achieve the usual power output.
▷ There may be a small amount of smoke from
the exhaust, even after stopping the engine.
Driving with the boot lid open
If there is no alternative to driving with the tail‐
gate open:
▷ Noise, for example caused by the radiator fan
running, may be heard, even some minutes
after stopping the engine.
▷ Close all the windows and the Glass Roof.
▷ Adjust the blower to a high setting.
▷ Maintain a moderate speed.
It is normal for the radiator fan to keep running
for several minutes, even after short trips.
Petrol engine: Cleaning the exhaust
gas particle filter while driving
Various driver profiles ensure that the exhaust
gas particle filter is self-cleaning. If, in addition to
the self-cleaning function, the exhaust gas parti‐
cle filter needs to be actively cleaned while driv‐
ing, a Check Control message is displayed.
Hot exhaust system
WARNING
During vehicle operation, high temperatures
may occur under the vehicle body, for example
due to the exhaust system. If flammable materi‐
als, for example leaves or grass, come into con‐
tact with hot parts of the exhaust system, these
materials can catch fire. There is a danger of in‐
jury or damage to property. Never remove the
heat shields fitted here or apply underseal to
them. Make sure that when driving, idling or
parking, no flammable materials can come into
contact with hot vehicle parts. Do not touch the
hot exhaust system.
Proceed as follows the next time you drive out‐
side of built-up areas for around 30 minutes:
▷ Deactivate cruise Control systems.
▷ Take your foot off the accelerator repeatedly
and allow the vehicle to roll in overrun mode,
see page 239.
▷ If possible, drive at alternating speeds.

than a maximum of 25 cm, 9.8 in.
▷ Drive through water at a walking speed of no
more than 5 km/h, 3 mph.
WARNING
Certain vehicle functions may be affected by in‐
terference from high-frequency radio signals.
Such signals originate from various transmitter
systems, for example from air traffic beacons or
relay stations for mobile telecommunications.
Safety note
NOTE
Driving through excessively deep water too fast
can result in water entering the engine com‐
partment, electrical system or transmission.
There is a risk of material damage. When driv‐
ing through water, do not exceed the maximum
water depth and speed specified above.
We recommend you consult a Service Partner
should you experience any difficulties in this re‐
gard.
Mobile communication in the
vehicle
Safe braking
WARNING
There is a possibility of reciprocal interference
between the vehicle electronics and mobile
radio devices. Radiation is generated when mo‐
bile radio devices are transmitting. There is a
danger of injury or damage to property. If possi‐
ble, only use mobile radio devices, for example
mobile telephones, in the interior if they are
connected directly to an external antenna in or‐
der to eliminate reciprocal interference and to
dissipate the radiation from vehicle's interior.
General
The vehicle is equipped with ABS as standard.
Perform full braking in situations that require it.
The vehicle remains steerable. Any obstacles
can be avoided by performing steering move‐
ments as smoothly as possible.
A pulsing of the brake pedal and hydraulic regu‐
lating sounds indicate that ABS is functioning.
In certain braking situations, the perforated brake
discs can cause functional noise. Functional
noises have no effect on the efficiency and op‐
erational safety of the brakes.
Aquaplaning
On wet or slushy roads, a wedge of water can
form between the tyres and the road.
Objects in the range of movement of
the pedals and in the footwell
This situation, known as aquaplaning, means that
the tyre can actually lose contact completely with
the road surface and the vehicle can neither be
steered, nor the brakes properly applied.
WARNING
Objects in the driver's footwell can restrict the
pedal travel or block a pedal that has been
pressed. There is a risk of accident. Stow items
in the vehicle so that they are secure and can‐
not get into the driver's footwell. Only use floor
mats that are suitable for the vehicle and can
be securely fastened to the floor. Do not use
loose floor mats, and do not place several floor

there is sufficient space for the pedals. Ensure
that floor mats are securely reattached after
having been removed, for example for cleaning.
ing force and steering. There is a risk of acci‐
dent. Do not drive at idle speed or with the en‐
gine switched off.
Corrosion of the brake discs
Wet roads
Corrosion of the brake discs and contamination
of the brake pads increase in the following cir‐
cumstances:
In damp weather, on gritted roads and in heavy
rain, apply the brakes lightly every few kilome‐
tres/miles.
▷ Low mileage.
Ensure that you do not obstruct other road users
when doing so.
▷ Extended periods when the vehicle is not
used.
The heat generated by braking dries the brake
discs and brake pads and protects them against
corrosion.
▷ Infrequent use of the brakes.
▷ Aggressive, acidic or alkaline cleaning agents.
During braking, corroded brake discs may cause
brake judder which usually cannot be eliminated.
This way, brake power is available immediately,
whenever it is needed.
Condensation when vehicle is
parked
When the automatic air conditioning is in opera‐
tion, condensation develops and exits under‐
neath the vehicle.
Downhill gradients
General
When driving on long or steep downhill
stretches, use the gear in which the least braking
is required. Otherwise the brake system can
overheat and the braking effect is reduced.
Driving on a racing track
Engine braking effect can be additionally in‐
creased by manually shifting down, even into first
gear, if applicable.
The higher mechanical and thermal loads in‐
volved in driving on racing tracks lead to in‐
creased wear. This wear is not covered by the
warranty. The vehicle is not conceived for use in
motor sports competitions.
Safety notes
WARNING
Before and after driving on a racing track, have
the vehicle checked at a Service Partner of the
manufacturer or another qualified Service Partner
or a specialist workshop.
Even slight continuous pressure on the brake
pedal can cause overheating, brake pad wear or
even brake system failure. There is a risk of ac‐
cident. Avoid excessive loads on the brake.
WARNING
When idling or with the engine switched off,
safety-relevant functions are restricted or no
longer available, for example the braking effect
of the engine or power assistance for the brak‐
