Switching the rear window heater on/off
When the heater is switched on, a lamp lights up inside the button.
The heating only works when the engine is running.
The heater automatically switches off after approximately 7 minutes.
For the sake of the environment
The heating should be switched off as soon as the window is de-iced or free
from mist. The reduced current consumption will have a favourable effect on
fuel economy.
Note
■ If the on-board voltage drops, the heater switches off automatically, in order
to provide sufficient electrical energy for the engine control » page 147, Auto-
matic load deactivation .■
If the light is flashing inside the button the heater is off due to low battery.

lights in the switch.WARNINGIf, as an occupant, you have a subdued pain and/or temperature sensitivity,
e.g. through medication, paralysis or because of chronic illness (e.g. diabe-
tes), we recommend you do not use seat heating on the driver or front pas-
senger seat. This can lead to burns on the back, the posterior and the legs
which are difficult to heal. If the seat heating is used, we recommend to
make regular breaks in your journey when driving long distances, so that
the body can recuperate from the stress of the journey. Please consult your
doctor, who can evaluate your specific condition.
CAUTION
■ Do not kneel on the seats or otherwise apply concentrated pressure to them.■The seat heating in the following cases will not turn on - there is a risk of
damaging the seat covers and seat heating. ■The seats are not occupied by people.
■ Items are fastened or stored items on the seats, such as a child seat, a bag
and the like.
■ Additional seat covers or protective covers are fixed to the seats.■

larged by folding the rear seats forward, ensure the safety of the passen-
gers transported on the other rear seats » page 11, Correct seated position
for the passengers in the rear seats .
■
If the rear seat next to the folded forward seat is occupied, ensure maxi-
mum safety, e.g. by placing the goods to be transported in such a way that
the seat is prevented from folding back in case of a rear collision.
■
Do not drive with the luggage compartment lid open or unlatched, other-
wise exhaust gases may get into the interior of the vehicle – risk of poison-
ing!
■
Do not exceed the permissible axle loads and permissible gross weight of
the vehicle – risk of accident!
■
Do not transport people in the boot!
CAUTION
■ Please ensure that the heating elements for the rear window heater are not
damaged as a result of abrasive objects.■
Tyre pressure must be adjusted to the load » page 149.

Seats without seat heating
Thoroughly vacuum the seat covers with a vacuum cleaner before cleaning.
Clean the seat covers with a damp cloth or cleaning products specially de-
signed for this purpose.
Indented points arising on the fabrics by everyday use, can be removed by
brushing against the direction of hair with a damp brush.
Always clean all parts of the covers, so that there are no visible edges. Then
allow the seat to dry completely.
CAUTION
■ Do not clean the covers of electrically heated seats either with water or with
other liquids - there is a risk of damaging the seat heating system.■
Regularly remove dust from the seat covers using a vacuum cleaner.
■
Electrically heated seats must not be dried after cleaning by switching on the
heater.
■
Do not sit on wet seats - risk of seat deformation.
■
Always clean the seats “from seam to seam”.
Safety belts

Inspecting and replenishing
Fuel
Introduction
This chapter contains information on the following subjects:
Refuelling
135
Lead-free petrol
135
Diesel fuel
136
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap » Fig. 116 on page 135 .
CAUTION
■
Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage!
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.
134General Maintenance
WARNING■When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical consumers and disconnect the negative
terminal
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger
must not be connected directly to the negative terminal of the vehicle battery,
but only to the engine earth » page 163, Jump-starting using the battery from
another vehicle .
Replacing
Read and observe
and on page 145 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.
Disconnecting and reconnecting
Read and observe
and on page 145 first.
Disconnecting
›
Switch off the ignition.
›First, disconnect the negative terminal
first, then the positive terminal
of the battery.
Connecting›
First, connect the positive
first, then the negative
battery terminal.
After disconnecting and re-connecting the vehicle battery, the following func-
tions or devices are partially or completely inoperative.
Function / deviceOperating measureRadio or navigation systemEnter code number » User radio
manual or » navigation system
user manualTime settings» page 33
CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 145 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the battery is put under high levels of strain. This manifests it-
self by the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and
rear window heaters have their power limited or are shut off completely in
the event of an emergency.
