Note■The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux.
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position

Conditions for the system function
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 145 .
The engine is automatically switched off; when the vehicle moves off, the
ignition process will be automatically initiated.
The engine is not automatically switched off.
Reasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, for the following reasons. ▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
When the engine is shut-down automatically and the system detects that the
engine is required such as when the brake pedal is pressed repeatedly then
the system automatically starts the engine.
Infotainment display
Information about the current status of the system can be displayed in the In-
fotainment display » Owner´s Manual Infotainment , chapter CAR - vehicle set-
tings .
Note
■
If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shut-down
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Running-in and economical driving
Introduction
This chapter contains information on the following subjects:
Running-in
132
Tips for economical driving
132
DriveGreen function
133
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Running-in
Driving in the engine
The engine has to be run in during the first 1500 kilometres. During this period,
the driving style decides on the quality of the driving-in process.
During the first 1 000 km we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and to dis-
pense with the trailer.
In the area of 1,000 to 1,500 kilometres the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
Drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner Observe the recommended gear » page 41.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
Reducing idling
If the vehicle is fitted with the START STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 205.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 0.3 l/100 km. At a speed
of 100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Only turn on electrical consumers (e.g. seat, window and mirror heating and
the like) for as long as necessary.
132Driving

CAUTIONInformation for cleaning windows■Do not clean the inside of the windows with sharp-edged objects or corro-
sive and acidic cleaning agents – there is a risk of damaging the heating ele-
ments or window aerial.■
When drying the windows after washing the vehicle, do not use window
leathers that have been used to polish the bodywork. Residues of preserva-
tives in the window leather can dirty the window and reduce visibility.
Headlight glasses
Read and observe
and on page 183 first.
Clean plastic front headlight lenses using clean, warm water and soap.
CAUTION
■The headlights are never to be wiped dry - there is a risk of damaging the
protective lacquer and the headlight glass subsequently developing cracks.■
Do not use sharp objects to clean the glasses - there is a risk of damaging
the protective lacquer and the headlight glasses subsequently developing
cracks.
■
Do not use any aggressive cleaning or chemical solvent products to clean the
headlights – risk of damaging the headlight lenses.
Camera lens
Read and observe
and on page 183 first.
Moisten the lens of the rear view camera first with clean water and then dry
with a dry cloth.
Remove the snow from the lens with a brush and the ice from the lens with
de-icing agents specifically developed for these purposes.
CAUTION
■ Remove snow or ice on the lens with warm or hot water - there is a risk of
damaging the lens.■
Never use cleaners containing abrasive effect to clean the lens.
■
Never use pressurized water or steam jet to clean the lens.
Door closing cylinder
Read and observe
and on page 183 first.
Specific products must be used for de-icing door lock cylinders.
CAUTION
Make sure that as little water as possible gets into the locking cylinder when
washing the vehicle - there is a risk of freezing the lock cylinder!
Cavity protection
Read and observe
and on page 183 first.
All the cavities of your vehicle which are at risk from corrosion are protected
for life by a layer of protective wax applied in the factory.
Wax protection does not require to be inspected or re-treated.
If any small amount of wax flow out of the cavities at high temperatures, these
must be removed with a plastic scraper and the stains cleaned using a petrole-
um cleaner.
WARNINGSafety regulations should be observed when using petroleum cleaner to re-
move wax – risk of fire!
Jack
Read and observe
and on page 183 first.
The jack is maintenance-free.
If necessary, the moving parts of the jack should be lubricated with a suitable
lubricant.
Wheels
Read and observe
and on page 183 first.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular
basis.
185Care and maintenance

Fabric
Clean upholstery cover materials and cloth trims on doors, luggage compart-
ment cover, etc. using specific cleaning agents, e.g., dry foam.
Use a soft sponge, brush, or commercially available microfibre cloth.
Use a cloth and a cleaning agent specifically designed for this purpose to clean the roof trim.
Remove any lumps on the cover fabric and any fabric residue using a brush.
Remove stubborn hair using a “cleaning glove”.
Alcantara ®
Dust and dirt in pores, creases and seams may chafe and damage the surface.
Therefore, they must be removed regularly at short intervals with a cloth or
vacuum cleaner.
Minor changes in colour caused by use are normal.
CAUTION
■ For Alcantara ®
seat covers, do not use any solvents, floor wax, shoe cream,
stain remover, leather cleaners or similar agents.■
Avoid leaving the vehicle in bright sunlight for long periods of time in order
to stop the artificial leather, materials or Alcantara ®
from bleaching. During ex-
tended periods of standing outdoors, protect artificial leather, fabrics or Alcan-
tara ®
by covering.
■
Some clothing materials, e.g. dark denim, do not have sufficient colour fast-
ness. This can cause damage or clearly visible discolouration to seat covers,
even when used correctly. This applies particularly to light-coloured seat cov-
ers. This does not relate to a fault in the seat cover, but rather to poor colour
fastness of the clothing textiles.
Seat covers
Read and observe
and on page 187 first.
Electrically heated seats
Use a specific cleaning agent such as dry foam or similar to clean the covers. »
.
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
Read and observe
and on page 187 first.
Wash dirty seat belts with mild soapy water.
Remove coarse dirt with a soft brush.
WARNING■ The seat belts must not be removed for cleaning.■Never clean the seat belts chemically as chemical cleaning products could
destroy the fabric.■
The seat belts must not be allowed to come into contact with corrosive
liquids (e.g. acids).
■
The seat belts must be fully dried before being rolled up.
