Problems with the auxiliary heating
Problem Possible causes/consequences and
0004 Solutions
The indicator lamp on
the remote control
flashes red rapidly. The remote control battery is discharged. Data transmission is not
possible.
X
Replace the remote control battery (Y page 126).The indicator lamp on
the remote control
flashes red and green in
rapid succession. There is no connection between the remote control and the
receiver in the vehicle.
X
Change your position in relation to the vehicle, e.g. hold the
remote control higher or to the side.
X Move closer.
If you cannot establish aconnection and the auxiliary heating is
switched on, it can then only be deactivated using the 0020button
(Y page 119). The indicator lamp on
the remote control
flashes red and green in
rapid succession. Several remote controls are being used at the same time.
X
Switch on the remote control again after a short while
(Y page 121). The indicator lamp on
the remote control
flashes red and green in
rapid succession. The remote control is not synchronized.
X
Synchronize the remote control (Y page 122).The indicator lamp on
the remote control
slowly flashes red and
green alternately. The remote control is being synchronized.
X
Wait until the remote control synchronization process is
complete (Y page 122). The remote control for
the auxiliary heating
cannot be switched on. The remote control battery is discharged.
X
Replace the remote control battery (Y page 126).The auxiliary heating
does not switch on. The outside temperature is above 39
‡(4† ). The auxiliary heating
switches off automatically. The auxiliary heating
switches off
automatically and/or
cannot be switched on. The fuel tan
kis less than 0002full. The auxiliary heating switches off
automatically.
X Refuel at the nearest gas station.

Problem Possible causes/consequences and
0004 Solutions
The auxiliary heating
switches off
automatically and/or
cannot be switched on. The low-voltage protection system integrated in the control unit
switches off the auxiliary heating because the on-board voltage is
less than 10 V.
X Have the alternator and battery checked. The auxiliary heating
switches off
automatically and/or
cannot be switched on. The fuse is blown.
X
Replace the fuse; see the "Fuse allocation" supplement.
X Have the cause of the blown fuse determined at a qualified
specialist workshop. The auxiliary heating
switches off
automatically and/or
cannot be switched on. A malfunction has occurred.
X
Switch the ignition on and off twice.
If the auxiliary heating still cannot be switched on, the heating
device is faulty.
X Have the auxiliary heating checked at a qualified specialist
workshop. The auxiliary heating is
overheated. The coolant level is too low.
X
Check the coolant level and add more coolant if necessary
(Y page 244). Operating the cargo compartment air
vents
If your vehicle is equipped with a roof
ventilator, you can ventilate and extract air
from the cargo compartment. X
Turn the key to position 2in the ignition
lock.
X To activate and extract air: press the
upper section of the 0009switch.
The roof ventilator removes used air from
the cargo compartment.
X To activate and ventilate: press the lower
section of the 0010switch.

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described
functions. This also applies to systems and
functions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Breaking-in notes
The first 1,000 miles (1,500 km)
New or replaced brake pads and brake disks
only reach their optimum braking effec tafter
100 miles (a few hundred kilometers). Until
then, compensate for this by applying greater
force to the brake pedal.
For the service life and economy of your
vehicle it is crucial that you brea kinthe
engine with due care.
R Therefore, protect the engine for the first
1,000 miles (1,500 km) by driving at
varying vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g.
driving at full throttle. Do not exceed 0001of
the maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance
(kickdown).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and
accelerate the vehicle up to full speed.
i You 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
G
WARNING
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.Y ou will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident .Release
the parking brake fully before driving off. Battery isolating switch
Important safety notes !
Make sure that the key is in position 0in
the ignition lock and wait at least
20 seconds before disconnecting or
connecting the battery isolating switch.
You could otherwise damage electrical
system components.
You can use the battery isolating switch to
disconnect the power supply to all your
vehicle's consumers. This will prevent
uncontrolled battery discharge caused by off-
load curren tconsumption.
If your vehicle is equipped with an auxiliary
battery in the engine compartment, you will
need to disconnect both batteries. Only then
is the electrical system fully disconnected
from the power supply. 132

Visual check of the vehicle exterior X
In particular, check the following
components on the vehicle, and on the
trailer as necessary:
R
license plates, vehicle lighting, turn
signals, brake lamps and wiper blades for
dirt and damage
R tires and wheels for firm seating, correct
tire pressure and general condition
R trailer tow hitch for play and security
i The trailer coupling is one of the most
importan tvehicle parts with regard to road
safety. The separate instructions issued by
the manufacturer pertaining to operation,
care and maintenance should be observed.
X Rectify any noticeable defects before
commencing the journey.
Checks in the vehicle Emergency equipment/first-aid kit
X
Check the equipment to make sure that it
is accessible, complete and ready for use.
The first aid and breakdown assistance
equipment is in the fron tdoor stowage
compartments and behind the driver's seat.

WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the
operating and road safety of the vehicle.
There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
When using floormats or carpets, make sure
that they are properly secured so that they do
not slip or obstruct the pedals. Only use non-
slip floormats. G
WARNING
Unsuitable footwear can hinder correc tusage
of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
X Secure the load as per the loading
guidelines (Y page 232).
X Make sure that the floormats and carpets
are properly secured so that they cannot
slip and obstruct the pedals.
X Close all doors. Starting the engine

gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
! Do not depress the accelerator pedal
when starting the engine.
