Coolant temperature gaugeFig. 4
Coolant temperature gauge
First read and observe the introductory information and safety warn-
ings on page 11.
The coolant temperature gauge » Fig. 4 only operates when the ignition is
switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine has
not yet reached its operating temperature. Avoid high speeds, full throttle and
high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer moves into the mid-range of the scale. At very high ambient temperatures or heavy en-
gine loads, the pointer may move even further to the right.
High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too high. Further information » page 22.
CAUTION
Additional headlights and other attached components in front of the air inlet im-
pair the cooling efficiency of the coolant.
Fuel gaugeFig. 5
Fuel gauge
First read and observe the introductory information and safety warn-
ings on page 11.
The fuel gauge » Fig. 5 only operates if the ignition is switched on.
The fuel tank has a capacity of about 50 litres. If the amount of fuel reaches the reserve area (the pointer reaches the red scale range), the indicator symbol illumi-
nates
to » page 25 .
CAUTION
Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring. This can result in considerable damage to parts of the engine
and the exhaust system.
Note
■ After filling up, it can occur that during dynamic driving (e.g. numerous curves,
braking, driving downhill and climbing a steep hill) the fuel gauge indicates ap-
prox. a fraction less. When stopping or during less dynamic driving, the fuel gauge displays the correct fuel level again. This is not a fault.■
The arrow next to the icon within the fuel gauge displays the installation
location of the fuel filler on the right side of the vehicle.

Switching on/offFig. 111
Button for switching on/off the system directly on the operating
part of the air conditioning/Climatronic
First read and observe the introductory information and safety warn-ings
on page 115.
The auxiliary heating (parking heating) can be switched on/off as follows.
Manually switching on using the button on the operating part of the manual air conditioning/Clima-
tronic. The indicator light in the button illuminates » Fig. 111.
by using the radio remote control » page 116
Manually switching off
using the button on the operating part of the manual air conditioning/Clima-
tronic. The indicator light in the button goes out » Fig. 111.
by using the radio remote control » page 116
After switching the system off, the auxiliary heating will continue running a little
while longer in order to burn the remaining fuel in the auxiliary heater.
After switching off the auxiliary heating, the coolant pump runs for a short period.
Switching on automatically
The auxiliary heater is switched on according to the Infotainment settings » Info-
tainment manual , chapter Vehicle settings .
When automatic switching on is activated, the indicator light in the symbol button lights up for about 10 seconds after the ignition is turned off.
Switching off automatically
Turning off the auxiliary heating (auxiliary heating) occurs in the following cases. › The set switch-off has been achieved
» Operating instructions for Infotainment ,
chapter Vehicle settings .
› The fuel level has reached the reserve area (the warning icon
illuminates).
› The charge state of the vehicle battery has reduced too much

Warning light
Switch on the auxiliary heating
Switch off the auxiliary heating
The transmitter and the battery are housed in the housing of the remote control. The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few hun-
dred metres. Obstacles between the radio remote control and the vehicle, bad
weather conditions and a weaker battery can clearly reduce the range.
To switch the auxiliary heating (aux. heating) on or off, hold the remote control
vertical, with the aerial
A
pointing upwards. The antenna must not be covered
with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio remote control, if the distance between the radio remote control and the vehicle is at
least 2 m.
AB116Using the system
›Place the filler cap onto the fuel filler neck and turn it clockwise until it securely
engages.›
Close the fuel filler flap until it clicks into place.
Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel enginesThe fuel filler tube on vehicles with diesel engines has been fitted with a incor-rect refuelling guard » Fig. 179. This guard means it is only possible to refuel with
the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to and fro with slight pressure to insert it correctly.
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Do not continue filling the fuel tank otherwise the expansion volume is filled up.■
Be careful when filling diesel fuel from the spare canister – danger of contami-
nating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect fu-
elling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, containing a reserve of approx.
7 litres .
Unleaded petrol
First read and observe the introductory information and safety warn-
ings
on page 212.
Your vehicle can only be operated with unleaded petrol in compliance with the
EN 228 1)
standard.
All petrol engines can be operated using petrol that contains at most 10% bioe-
thanol (E10).
Required fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with the octane rating 95 RON. Unleaded petrol with the oc-
tane ratings 91, 92 or 93 RON can also be used, but may result in a slight loss in
performance.
Prescribed fuel – unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON or higher.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if petrol with the octane rating 95 RON is not available »
.
Prescribed fuel – unleaded petrol 98/(95) RON Use unleaded fuel with the octane rating 98 RON or higher. Unleaded petrol
95 RON can also be used but results in a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if unleaded fuel with octane rating 98 RON or 95 RON is not availa-
ble »
.
Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1)
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel addi-
tives are used. This can result in considerable damage to parts of the engine or
the exhaust system.
CAUTION
■ Even filling the tank with leaded petrol that does not meet the standards once
can lead to serious damage to parts of the exhaust system!■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is used by mistake, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We recom-
mend that you have the fuel system cleaned by a specialist garage.
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2
or E5 for unleaded petrol with octane number 95 and 98.
