The START-STOPsystem (hereinafter referred to only as system) saves fuel
and reduces harmful emissions and CO 2 discharge.
If the system determine that the engine is not needed when the vehicle stops
(e.g. at the traffic lights), it turns off the engine and starts it again when mov-
ing off.
Operation
Fig. 114
Display
For the system-dependent automatic engine shut-down when stopping to op-
erate, the following conditions must be met.
For vehicles with manual transmission , the shift lever is in the neutral po-
sition and the clutch pedal is not depressed.
For vehicles with automatic transmission the brake pedal is to be de-
pressed.
The driver's door is closed.
104Driving
Downloaded from www.Manualslib.com manuals search engine The driver has fastened the seat belt.
The bonnet is closed.
The driving speed exceeded 4 km/h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function cannot be either influ-
enced or recognised by the driver. Therefore, the system can react differently
in situations which are identical from the driver's view.
The information as to whether the conditions are met for the automatic en-
gine shut-off, are shown in the display » Fig. 114.
The motor is automatically switched off.
The engine is not turned off when you stop (the conditions for the auto-
matic motor shut-down are not met).
Reasons for the engine running
Running the engine can be essential, 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 indoor 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 » operating instructions for Infotainment , chapter CAR -
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 sys-
tem.■
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 shutdown
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.

ted in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.
WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control
of the vehicle – there is a risk of an accident.
Running-in and economical driving
Introduction
This chapter contains information on the following subjects:
Running-in
111
Tips for economical driving
111
DriveGreen function
112The 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 1 500 kilometres. During this peri-
od, 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 not to use
a trailer.
In the range 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.
Change gear in an energy saving and timely manner
Observe the recommended gear » page 39.
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.
111Starting-off and driving
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

112Driving
Downloaded from www.Manualslib.com manuals search engine Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.

The fatigue detection system (hereinafter referred to only as system) recom-
mends the driver taking a break from driving when, because of the driver's
steering behaviour, driver fatigue can be detected.
WARNING■ For the driving ability is always the driver's responsibility. Never drive if
you feel tired.■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Function
Read and observe
on page 125 first.
From the start of the journey, the system evaluates steering behaviour. If,
while driving, there have been changes in the steering behaviours that are
evaluated by the system as indicating possible fatigue, a break recommenda-
tion is issued.
The system evaluates steering behaviour and recommends a break at speeds
of 65 - 200 km/h.
The system detects a break from driving when one of the following condi-
tions is met.
› The vehicle is stopped and the ignition switched off.
› The vehicle is stopped, the seat belt removed and the driver's door opened.
› The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
The system can be activated or deactivated in the Infotainment » Operating
instructions Infotainment , chapter CAR - vehicle settings .
