Changing bulbs
Important safety notes
GDANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
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.
If your vehicle is equipped with Bi-Xenon bulbs,
you can recognize this by the following: the cone
of light from the Xenon bulbs moves from the
top to the bottom and back again when you start
the engine. For this to be observed, the low-
beam headlamps must be switched on before
starting the engine.
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 vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
RDo not touch the glass tube of new bulbs with your bare hands. Always use a clean, lint-free
cloth or only touch the base of the bulb when
installing.
Even minor contamination can burn into the
glass surface and reduce the service life of the
bulbs.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could explode.
ROnly use bulbs in closed lamps which have
been designed for this purpose.
ROnly use spare bulbs of the same type and
with the prescribed voltage
RProtect the bulbs from moisture when in use.
If the new bulb still does not light up, consult a
qualified specialist workshop.
RHave the LEDs and bulbs of the following
lamps changed at a qualified specialist work-
shop:
-the additional turn signals in the exterior
mirrors
-the high-mounted brake lamp
-LED daytime running lamps (Bi-Xenon
headlamps)
-Bi-Xenon lamps (Bi-Xenon headlamps)
-front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.

Driving and parking
Z

Always park your vehicle safely and according to
legal requirements and secure it against rolling
away.
To ensure that the vehicle is properly secured
against rolling away unintentionally:
Rthe parking brake must be firmly applied
Rthe selector lever must be in positionPand
the key must be removed from the ignition
lock
Ron steep uphill or downhill gradients, the front
wheels must be turned towards the curb
Rthe rear axle must be secured, e.g. with a
wheel chock, on steep uphill or downhill gra-
dients
Use the wheel chock (
Ypage 131) to do so.
If you leave the vehicle parked for more than
three weeks:
Rconnect the batteries to a trickle charger or
Rdisconnect the vehicle's starter battery or
Rswitch off the electrical system using the bat-
tery main switch (Ypage 118) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con-
dition of charge every 3 weeks, since standby
power consumption can drain the battery. If the
battery voltage is lower than 12.2 V,the battery
must be charged. Otherwise, the battery may be damaged by exhaustive discharging.
Be sure to observe the notes on disconnecting
and charging the batte
ries under "Bat-
tery“ (Ypage 228). You can obtain information
about trickle chargers from a qualified specialist
workshop.
Parking brake
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking brake
when the vehicle is stationary.

Driving an d parking

XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action provided it is safe to do
so.
If you want the distance warning function to
assist you, the function must be activated and
operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of 45 mph (70 km/h), the distance
warning function can also react to stationary
obstacles, such as stopped or parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision, the
system will alert you both visually and acousti-
cally.
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt, ice or anything else covering the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
spe eds w
here there is no visible damage to the
front of the vehicle.
Activating/deactivating the distance
warning function
When you switch on the engine, the distance
warning function switches on after a few sec-
onds.
XTo deactivate: press theæbutton

Adaptive Brake Assist
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 54).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rto stationary obstacles
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.

Rear view camera
Important safety notes
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering, parking and pulling away. When
maneuvering, parking and pulling away, make
sure that there are no persons, animals or
objects in the maneuvering area.
The rear view camera is a visual parking aid.
Information on operation can be found in the
separate Audio 15 supplement.
The camera is in the middle of the roof above the
high-mounted brake lamp (
Ypage 237).
You can find information on cleaning the camera
in the "Maintenance and care" section
(
Ypage 237).
Working mode
ADR (working speed governor)
General notes
When activated, ADR automatically increases
the engine speed to a preset speed or a speed
you have set.
iAfter a cold start, the idling speed of the
engine is increased automatically. If the pre-
set working speed is lower than the increased idling speed, the working speed is only
reached once the engine has completed the
warm-up phase.
It is only possible to activate ADR with the
vehicle stationary and the parking brake
applied.
The selector lever of the automatic transmis-
sion must be in position P.

ing to. Information is available from the police
and local authorities.
Observe the following when towing a trailer:
RPractice driving around bends, stopping and
backing up at a place where there is no traffic.This enables you to gain experience and get
used to the new handling characteristics.
RBefore driving, check:
-that the trailer tow hitch and ball coupling
are secure
-that the safety switch for a braked trailer is
functioning properly
-that the safety chains are secure and not
damaged
-that the electrical connections are secure
-that the lights are working
-that the wheels are in good order and the
tire pressure is correct
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer is equipped with an individual
braking system, check before each journey
whether the brakes are functioning correctly.
RIf the trailer has electronically controlled
brakes, pull the vehicle/trailer combination
away carefully. Brake manually using the
brake controller and check that the brakes
are working.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 215).
RWhen driving with a trailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has a decreased
gradient climbing capability and a long er
brak

ing distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the force on the
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines, restrict the shift range. Select shift range
4,3,
2 or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
RWhen driving on a downhill gradient, shift to a
low gear and take advantage of the engine's
braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switching the airflow and the temperature of
the heater/air conditioning to the maximum
level. Open the windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com-
bination you need an additional distance
before you can return to your original lane.
Uncoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
!Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XMake sure the selector lever of the automatic
transmission is in position P.
XApply the parking brake of the vehicle.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away with a wheel chock or similar object.
XRemove the trailer cable and safety chains
and decouple the trailer.
