Replacing bulbs
Important safety notes
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the ignition before replacing bulbs in the lighting system. This will prevent
a short circuit.
RWear gloves and eye protection when chang-
ing a bulb.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube. The bulb
could may explode.
RA bulb could explode if:
-you touch it
-it is hot
-you drop it
-you scratch or score it
RMarks on the glass tube shorten the operating
life of a bulb. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit. Then rub
off the glass tube with a clean, lint-free cloth.
RMake sure that bulbs are protected from
moisture when operating and that they do not
come into contact with liquids. Make sure
that seals are seated correctly and replace
damaged seals.
RCheck the contacts for signs of corrosion and
clean these if required.
ROnly operate bulbs in closed lamps which
have been designed for this purpose.
ROnly use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
RIf the new bulb does not light up, consult a
qualified specialist workshop.
RHave lamps with LED bulbs repaired at a quali- fied specialist workshop only.
RHave the bulbs of the following lamps
replaced at a qualified specialist workshop
only:
-the additional brake lamps
-the license plate lighting
-Front fog lamps
-side marker lamp
Please also observe the notes on the interior
lights (

Breaking-in notes
Important safety notes
In certain driving and driving safety systems, the
sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been
delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
procedure.
New or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force to
the brake pedal.
The first 1000 miles (1500 km)
For the service life and economy of your vehicle
it is crucial that you break in the engine with due
care.
RTherefore, protect the engine for the first
1000 miles (1500 km) by driving at varying
vehicle and engine speeds.
RAvoid overstraining the vehicle and high
engine speeds during this period, e.g. driving
at full throttle. Do not exceed Øof the per-
missible maximum speed for each gear.
RDo not change down a gear manually in order to brake.
RTry to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
iYou should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced.
Driving
Important safety notes
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Warm up the engine quickly. Do not use the
engine's full performance until it has reached
operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
120Driving
Driving and parking

Hill start assist
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. Hill
start assist automatically maintains the brake
pressure for about another second, after you
have taken your foot off the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or a
downhill gradient
Rthe transmission is in position N
Rthe parking brake is applied
RESP®is malfunctioning
Reverse warning device
GWARNING
Other road users may ignore or fail to hear the warning tone of the reverse warning feature.
There is a risk of injury if you fail to ensure that
the area in which you are maneuvering is
clear.
Make sure that there are no persons or
objects in the area in which you are maneu-
vering. It may be necessary to enlist the help
of a second person when maneuvering.
The reverse warning feature is a system
designed to assist you in ensuring the safety of
other road users.
A warning signal sounds to alert other road
users when reverse gear is engaged. The volume
of the warning tone can be reduced for night-
time driving.
XTo reduce the volume of the warning tone:
engage reverse gear twice in quick succes-
sion.
The warning tone is now quieter.
iThe warning tone sounds at a normal vol-
ume by default. The volume of the warning
tone has to be reduced each time you engage
reverse gear if necessary.
ECO start/stop function
General notes
When the ECO start/stop function is opera-
tional, it switches the engine off automatically if
the vehicle is slowed to a stop under certain
conditions.
When pulling away again, it starts the engine
automatically. The ECO start/stop function
thereby helps you to reduce the fuel consump-
tion and emissions of your vehicle.
The stop/start function is automatically activa-
ted each time you start the engine with the key.
In drive program Mthe ECO start/stop function
is automatically deactivated. You can manually
activate the ECO start/stop function if required.
Display (example for vehicles without steering
wheel buttons)
Display (example for vehicles with steering wheel
buttons)
If the display shows èECO symbol :in the
status area or in the footer, the ECO start/stop
function will switch the engine off automatically
when the vehicle comes to a stop.
