Downloaded from www.Manualslib.com manuals search engine 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 161.
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
Electrical consumers (e.g. seat heating, air conditioning and the like) should
only be turned on for as long as necessary.
Use the cooling system economically
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be switched on if the windows are open.DriveGreen functionFig. 121

Graphical review summary
The evaluation of the driving economy during the last 3 minutes or 1.5 minutes
(depending on type of Infotainment) is shown like a beam in 5-second incre-
ments. The current status is shown on the left and moves gradually to the
right. The higher the green bars, the more economic the driving style is.
D
Scoring
In the function key, the evaluation of driving efficiency is shown from the start
in the range from 0 to 100 points. The higher the indicated value, the more
economic the driving style is.
When you press the function key, a detailed assessment showing the driving
efficiency during the last 30 minutes is shown.

In case of low oil level, the display of the instrument cluster shows a check
mark
as well as the relevant notification » page 37. Check the oil level using
the dipstick as soon as possible. Add oil accordingly.
CAUTION
■ The oil level must never be above the range A » Fig. 159 - risk of damage to
the motor as well as the exhaust system.■
If for some reason, it is not possible to top up the engine oil under the cur-
rent circumstances,
do not continue driving! Switch off the engine and seek
assistance from a specialist garage.

fications » page 153 .

Coolant
Introduction
This chapter contains information on the following subjects:
Checking the coolant level
155
Replenishing
155
The coolant provides cooling for the motor.
It consists of water and coolant additive with additives that protect the cooling
system against corrosion and prevents furring.
The coolant additive level in the coolant must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec- essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir » Fig. 160 on page 155 .WARNINGThe engine compartment of your car is a hazardous area. While working in
the engine compartment, be sure to observe the following warnings
» page 149 .■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
Consult a doctor immediately if coolant is swallowed.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■ Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
With an empty expansion tank top up coolant. The system could ventilate -
there is a risk of engine damage,
not continue! Switch off the engine and
seek assistance from a specialist garage.
■
The amount of coolant additive in the coolant must never be allowed to fall
below 40 %.
■
Over 60 % coolant additive in the coolant reduces the antifreeze protection
and coolant effectiveness.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.
■
Do not fill the coolant above the mark
A
» Fig. 160 on page 155 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
154General Maintenance
Downloaded from www.Manualslib.com manuals search engine ■Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.

Mark for the lowest permissible coolant level
The coolant level should be kept between the marks

The coolant can be checked and topped up, if the following conditions are sat-
isfied.
The vehicle is standing on a horizontal surface.
The engine is turned off.
The engine is not heated.
The bonnet is open.
Check the status
›
Check the level of coolant at the coolant expansion vessel » Fig. 160.
If the engine is warm, the test result may be inaccurate. The stand can also be
above the mark
A
» Fig. 160 .
In case of low coolant level, the control symbol is displayed in the instrument
cluster as well as the relevant notification
» page 36,
Coolant
in the in-
strument cluster. We still recommend inspecting the coolant level directly at
the reservoir from time to time.
ABLoss of coolant
A loss of coolant is first and foremost an indication of a leak in the cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe
and on page 154 first.
The coolant expansion tank should always contain a small amount of coolant» page 154, in section Introduction .
›
Place a cloth over the cap of the coolant expansion tank and carefully un-
screw the cap.
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
CAUTION
■ Only top up with new coolant.■Do not use an alternative additive if the specified coolant is not available. In
this case, use just water and have the correct mixing ratio of water and cool-
ant additive restored by a specialist garage as soon as possible.
