Rear window defroster
Rear window defroster switch
The rear window defroster consumes a lot of
power. You should therefore switch it off as
soon as the window is clear. The rear window
defroster otherwise switches off automati-
cally after 12 minutes.
X Start the engine.
X To switch on/off: press the0071switch.
The indicator lamp in the 0071button
comes on when the rear window defroster
is switched on.
If the indicator lamp in the 0071rear window
defroster button flashes, the on-board volt-
age is too low. The rear window defroster has
switched off prematurely or cannot be acti-
vated.
X Switch off any consumers that are not
required, e.g. reading lamps or interior
lighting.
If enough on-board voltage is available again
within 30 seconds, the rear window defroster
automatically switches on again. It otherwise
remains switched off. Switching air-recirculation mode on/
off
Important safety notes When you switch on air-recirculation mode,
the windows could fog up more quickly, in
particular at low outside temperatures. Only switch on air-recirculation mode for a short
time.
You can deactivate the intake of fresh air if
unpleasant odors enter the vehicle from out-
side. The air inside the vehicle will only be
circulated.
Heating/air-conditioning system
Air-recirculation mode switches off automat-
ically after about 10to 30 minutes, depending
on the outside temperature.
X Switch on climate control (Y page 116).
X To switch on/off: press the008Aswitch.
If the indicator lamp in the 008Abutton

G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck
in snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating run-
ning, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure an
adequate supply of fresh air, open a window
on the side of the vehicle that is not facing
into the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system. Flammable material such
as leaves, grass or twigs may ignite if they
come into contact with hot parts of the
exhaust system. There is a risk of fire.
When the auxiliary heating is switched on,
make sure that no flammable material can
come into contact with hot vehicle compo-
nents.
! Turn on the auxiliary heating at least once
a month for approximately 10 minutes. The
auxiliary heating could otherwise be dam-
aged.
! Make sure that the flow of hot air is not
blocked. The auxiliary heating will other-
wise overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary
warm-air heater. Adjustment and operation of
the:
R hot-water auxiliary heater is done via the
on-board computer and with the auxiliary
heating button in the control panel
(Y page 124) or with the remote control
(Y page 125).
R auxiliary warm-air heater is done via the
timer above the overhead control panel
(Y page 127).
The auxiliary heating works independently of
the engine and supplements the climate 122
Operating the auxiliary heating systemClimate control

Observe the following when towing a trailer:
R Practice 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 charac-
teristics.
R Before driving, check:
-that the trailer tow hitch and ball cou-
pling 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
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer has electronically controlled
brakes, pull the vehicle/trailer combina-
tion away carefully. Brake manually using
the brake controller and check that the
brakes are working.
R Secure the load on the trailer according to
the applicable specifications and current
standards on securing loads
(Y page 244).
R When driving with a trailer, check at regular
intervals that the load is secured and that
the brakes and lights are working.
R Bear in mind that the handling will be less
stable when towing a trailer than when driv-
ing without one. Avoid sudden steering
movements.
R The 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.
R If possible, do not brake suddenly, but
rather moderately at first so that the trailer can activate its brakes. Then increase the
force on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears when driving on
inclines, restrict the shift range. Select shift
range 4,3,2or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
R When 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
installed, the trailer brakes.
R If the coolant temperature increases dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can also be dissipated by
switching the airflow and the temperature
of the heater/air conditioning to the maxi-
mum level. Open the windows if necessary.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination you need an additional dis-
tance before you can return to your original
lane. Uncoupling a trailer
G
WARNING
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 rebound-
ing of the overrun brake. Towing a trailer

lent of 1 bar.
Load index
In addition to the load bearing index, a load
index can be stamped onto the sidewall of the
tire. It specifies the load-bearing capacity of
the tire more precisely.
Curb weight
The weight of a vehicle with standard equip-
ment including the maximum filling capacity
of fuel, oil, and coolant. It also includes the
air-conditioning system and optional equip-
ment if these are installed on the vehicle, but
does not include passengers or luggage.
Maximum tire load
The maximum tire load in kilograms or
pounds is the maximum weight for which a
tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two.
PSI (Pounds per square inch)
Standard unit of measurement for tire pres-
sure.
Aspect ratio
Relationship between tire height and width in
percent.
Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's sur-
face. Tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
Tire pressure should only be corrected when
the tires are cold. Cold tire pressure
The tires are cold:
R
if the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
R if the vehicle has not been driven further
than 1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact
with the road.
Tire bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.

Fuel consumption depends on:
R the vehicle version
R the style of driving
R the operating conditions
R the type or quality of the fuel used
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in city traffic
R during short journeys
R on mountainous terrain
R when towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (Y page 22).
The following components of the different
vehicle versions influence fuel consumption:
R tire sizes, tire tread, tire pressure, tire con-
dition
R body
R transmission ratios for the drive assem-
blies
R additional equipment (e.g. air-conditioning
system, auxiliary heating system).
For these reasons, the actual consumption
figures for your vehicle may deviate from the
consumption figures determined according
to EU Directive 80/1268/EEC.
Data concerning fuel consumption are
recorded in the on-board computer; use the
steering wheel buttons to call up the Trip
computer menu (Ypage 197). Diesel Exhaust Fluid (DEF) General notes
!
Only use DEF in accordance with
ISO 22241. The exhaust gas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other reduc-
ing agents will invalidate the New Vehicle
Limited Warranty.
! If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
High ambient temperatures
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape. Ammonia vapors have a pungent
odor and are particularly irritating for your
skin, respiratory organs and eyes. This may
result in burning eyes, nose and throat, as
well as coughing and watering eyes. Do not
inhale ammonia vapors.
If DEF heats up, e.g. in direct sunlight, in the
DEF supply reservoir for some time to over
122 ‡ (50 †), ammonia vapor will develop.
Low ambient temperatures
DEF freezes at a temperature of approx-
imately 12 ‡(00F811 †). The vehicle is equipped
with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed
at temperatures under 12 ‡ (00F811 †).
Additives and tap water
! Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise,
the exhaust gas aftertreatment may be
damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi-
tives or tap water will invalidate the New
Vehicle Limited Warranty. 324

If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion inhibi-
tor/antifreeze additive. The water used as
part of the coolant mixture must fulfill certain
requirements; these are usually fulfilled by
drinking water. If the water quality is not suf-
ficient, you must treat the water.

Washer fluid
Important safety notes G
WARNING
Windshield washer concentrate is highly flam-
mable. If it comes into contact with hot engine
components or the exhaust system it could
ignite. There is a risk of fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps.
Observe also the safety notes in the "Service
products and capacities" section.
Mixing ratio Add windshield washer concentrate to the
washer fluid all year round. Adapt the mixing
ratio to the ambient temperature.
At temperatures above freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Summerwash to prevent
smearing.
At temperatures below freezing:
X Fill up the washer fluid reservoir with a mix-
ture of water and windshield washer con-
centrate, e.g. Winterwash if there is a dan-
ger of frost.
This prevents washer fluid from freezing on
the windshield. 330
