Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
!If the coolant temperature is very high, e.g.
after driving on hilly roads, leave the engine
running at idle speed for about two minutes
before turning it off.
This allows the coolant temperature to return
to normal.
Vehicles with automatic transmission
XStop the vehicle.
XShift the transmission to position P.
XApply the parking brake.
XTurn the key to position0in the ignition lock
and remove it.
The immobilizer is activated.
If you switch the engine off with the trans-
mission in position Ror D, the automatic
transmission shifts to Nautomatically.
If you then open one of the front doors or
remove the key from the ignition, the auto-
matic transmission automatically shifts to P.
If you shift the automatic transmission to N
before switching off the engine, the automatic
transmission remains in Neven if a front door
is opened.
XSecure the vehicle to prevent it from rolling
away (Ypage 135).
Parking the vehicle for a long period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
XDisconnect the battery (Ypage 261).
or
XConnect the battery to a trickle charger.
Be sure to observe the notes on charging the batteries (
Ypage 264).
You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked for longer than 6
weeks, the vehicle may suffer damage as a
result of lack of use.
XVisit a qualified specialist workshop and seek
advice.
Driving tips
General notes
Important safety notes
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 you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements of the country in
which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while driving a vehicle.
Driving tips137
Driving and parking
Z

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 a separate func-
tional braking system, check before each
journey whether the brakes are functioning
correctly.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 246).
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 longer
braking 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 air conditioning to the
maximum level.
Open t

he 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 that the selector lever of the auto-
matic transmission is in position P.
XEngage the vehicle's parking brake.
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.
168Towing a trailer
Driving and parking

On vehicles with steering wheel buttons, the
light sensor in the instrument cluster automati-
cally controls the brightness of the display light-
ing.
While the lights are on, the brightness is depend-
ent upon the brightness of the ambient light.
You can also adjust the brightness of the instru-
ment lighting and the display lighting
Rby pressing thefand gbuttons on the
instrument cluster on vehicles without steer-
ing wheel buttons (not in the Settings
menu)
Rby turning brightness control knob :on vehi-
cles with steering wheel buttons
Speedometer
If you change the wheel size on your vehicle,
make sure it is assigned to the correct wheel
size category (
Ypage 279). If you change wheel
size category without recoding the control unit,
the speedometer indication will be inaccurate.
The current vehicle speed may then be higher
than the speed displayed in the speedometer.
The speed can also be shown in the display in
the form of a digital speedometer:
ROn vehicles without steering wheel buttons
(Ypage 175)
ROn vehicles with steering wheel buttons
(Ypage 181)
iIn some countries, a warning sounds and/or
the display shows a message when the vehi-
cle reaches the maximum legally permissible speed limit, e.g. at 75 mph (120 km/h).
Tachometer
!
Do not drive in the overrevving range, as this
could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment as
a result of increased emissions.
The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Please bear in mind that the outside tempera-
ture display shows the air temperature meas-
ured and not the road temperature.
The display shows the outside temperature in
the header:
Ron vehicles without steering wheel buttons
(Ypage 173)
Ron vehicles with steering wheel buttons
(Ypage 179)
Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature gauge
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
On vehicles without steering wheel buttons, you
can have the coolant temperature shown in the
display (
Ypage 175).
On vehicles with steering wheel buttons, an ana-
log coolant temperature gage is located in the
tachometer in the instrument cluster
(
Ypage 39).
Under normal operating conditions and with the
specified coolant level, the gauge may rise to
248 ‡ (120 †).
