Efficient handling of the cooling system
Read and observe
and on page 116 first.
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 on if the windows are open.
For the sake of the environment
Pollutant emissions are also lower when fuel is being saved » page 136.
malfunctions
Read and observe
and on page 116 first.
If the cooling system does not operate at outside temperatures higher than
+5 °C, there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 229 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 32.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
Auxiliary heating (auxiliary heating and ventilation)
Introduction
This chapter contains information on the following subjects:
Switching on/off
122
Radio remote control
123Conditions for the functioning of auxiliary heating (auxiliary heating and venti-
lation), hereinafter referred to only as auxiliary heating.
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon
is not lit in the display of
the instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (parking heating)
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heater functions in connection with the air-conditioning system
or Climatronic.
The auxiliary heating also warms up the engine.
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The heater is switched on or off automatically depending on the ambient con-
ditions to give the best possible conditions for the engine running and the in-
terior heating.
The automatic switching on and off of the heater can be turned off by a spe-
cialist garage.WARNING■ The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, do not park the car in places
where the exhaust fumes can come into contact with flammable materials
such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of fire.
121Heating and air conditioning

CAUTION■The running auxiliary heater consumes fuel from the vehicle tank and auto-
matically controls the filling level. If only a low quantity of fuel is present in the
fuel tank, the auxiliary heating switches off.■
The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating switches on the blower B » Fig. 125 on page 119 orC » Fig. 126 on page 119 only if it has achieved a coolant temperature of ap-
prox. 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-
iliary heating, you must maintain the comfort temperature normally selected
by you, leave the fan switched on and leave the air outlet vents in an open po-
sition. It is recommended to put the air flow in the position
or
.
Switching on/off

Read and observe and on page 121 first.
The auxiliary heating can be switched on/off as follows.
Manually switching on Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button illuminates » Fig. 127.
By using the radio remote control » page 123.
Manually switching off Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button goes out » Fig. 127.
By using the radio remote control » page 123.
After switching the system off, the auxiliary heating will continue running a lit- tle while longer in order to burn the remaining fuel in the auxiliary heater.
After switching off the auxiliary heating, the coolant pump still runs for a short
period.
Switching on automatically
The auxiliary heater is switched on according to the Infotainment set-
tings » Infotainment 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 occurs in the following cases.
› The switch-off time set in Infotainment has been achieved
» Operating in-
structions 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

Retraction and economical driving
Introduction
This chapter contains information on the following subjects:
Driving in
136
Tips for economical driving
136
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Driving 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 46.
Avoid full throttle and high speeds
Fuel consumption will be halved if only three-quarters of the possible top
speed of your vehicle is used.
Reducing idling
When the engine is switched off, such as when waiting in a traffic jam, the fuel
economy is already greater after 30 - 40 s than the fuel quantity which is re-
quired 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 204.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 1 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) only turn
on for as long as necessary.
In Infotainment, the display is shown of up to three consumers which are cur-
rently showing the highest degree of fuel consumption » Infotainment operat-
ing instructions , chapter Vehicle settings (CAR button) .136Driving

The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.
WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions of the system
Fig. 156
Engine is automatically switched
off / automatic engine cut off is
not possible
Read and observe on page 158 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
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.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If, after stopping the vehicle, the check icon
» Fig. 156 appears on the dis-
play, then the conditions for automatic engine shutdown are not met.
Running the engine is essential for the following reasons, for example.
› 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).
Information about the current status of the system can be displayed in the In-
fotainment display » operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
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.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.
Operation in vehicles with manual gearbox
Read and observe
on page 158 first.
In compliance with the operating conditions, automatic engine shutdown / au-
tomatic engine start takes place as described.

Trailer operation
Driving speed
For safety reasons, do not drive faster than 80 km/h when hitching a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake.
Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand
area or the red area of the scale, the speed must be reduced immediately.
Stop and switch off the engine if the warning symbol in the instrument clus-
ter » page 41 lights up.
The following information must be observed » page 41,
Coolant
.
The coolant temperature can be reduced by switching on the heating.WARNING■ Always drive particularly carefully with the trailer.■Adapt your speed to the conditions of the road surface and to the traffic
situation.
CAUTION
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Anti-theft alarm system
If the vehicle is locked, the alarm is activated when the electrical connection to
the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 59 .
Conditions for including a trailer in the anti-theft alarm system.
