START-STOPsystem
Introduction
This chapter contains information on the following subjects:
Operation
97
Manually deactivating/activating the system
97
The START-STOPsystem (hereinafter referred to as: the system) reduces CO 2emissions and harmful emissions, and saves fuel.
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.
The system function depends on many factors. Some of them are down to the
driver, the others are systemic and can neither be influenced nor identified.
Therefore the system may react differently in situations which seem identi-
cal from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even where this has previously been manually deactivated with the button
).
Note
If the engine has stopped due to the system, the ignition remains on.96Driving
OperationFig. 118
Display
Vehicles with manual transmission
The engine is automatically switched offas soon as the vehicle comes to a halt,
the shift lever is moved into neutral and the clutch pedal is released.
The engine is automatically startedas soon as the clutch pedal is depressed.
Vehicles with automatic transmission
The engine is automatically switched offas soon as the vehicle comes to a
standstill and the brake pedal is operated.
The engine is automatically startedas soon as the brake pedal is released.
Requirements for the system to function correctly
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. 118 .
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.
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶ 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 output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en-
gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
Note
■ If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted 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.

the automatic start process takes place.97Starting-off and Driving
Brakes and Parking
Introduction
This chapter contains information on the following subjects:
Handbrake
98
Parking
99
The wear and tear on the brake pads is dependent on the operating condi-
tions and driving style. In difficult conditions (e.g. urban, sporty driving), the
condition of the brakes should be checked between services by a specialist ga-
rage.
Brake response can be slower if the brakes are covered in moisture or, in win-
ter, have a layer of ice or salt on them . The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can occur if the vehicle
has been parked for a long period and if you do not make much use of the
braking system. The brakes are cleaned by applying the brakes several times
over »
.
Before negotiating a long or steep gradient , reduce speed and shift down a
gear. As a result, the braking effect of the engine will be used, reducing the
load on the brakes. If, nevertheless, there is a need for additional braking, it
should be carried out at intervals.
Emergency braking warning - If it is necessary to brake hard, the system may
cause the brake lights to automatically flash, to alert the traffic behind.
New brake pads must first be ““run in”” because these do not initially have the
best possible braking effect. Drive especially carefully for the first 200 km or
so.
If the brake fluid level is too low, it can cause faults in the braking system ;
the warning light will light up in the instrument cluster » page 32
,
Braking
system . If the warning light does not light up, yet the stopping distance is per-
ceived to be longer than before, the driving style should be adapted in view of
the unknown cause of the problem, and braking kept to a minimum - seek the
help of a specialist garage without delay.
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
When braking in a vehicle with manual transmission, when the vehicle is
in gear and at low revs, the clutch pedal must be depressed. Otherwise, the
functionality of the brake system may be impaired – risk of accident!
■
Do not depress the brake pedal, if there is no requirement to slow down.
This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear - risk of accident!
■
Only brake for the purpose of drying and cleaning the brake discs if the
traffic conditions permit this. Do not place any other road users in jeopardy.
■
Recommendations for new brake pads should be followed.
■
When stopping and parking, the parking brake should always be applied
firmly, otherwise the vehicle could move off - risk of accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
Otherwise, the front brakes could be in danger of overheating – risk of acci-
dent!
Handbrake

button » Fig. 120 .
98Driving
›Move the lever right down while pressing the lock button.
The handbrake warning light
lights up when the handbrake is applied, pro-
vided the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied. The handbrake warning is activated if the vehicle is driven
at a speed of over 5 km/h for more than 3 seconds.WARNINGDisengage the handbrake completely. A handbrake which is only partially
disengaged can result in the rear brakes overheating. This can have a nega-
tive effect on the operation of the brake system – risk of accident!
Parking

WARNING■
The parts of the exhaust system can become very hot. Therefore, never
stop the vehicle in places where the underside of your vehicle could come
into contact with flammable materials (e.g. dry grass, leaves, spilled fuel or
the like). - Risk of fire and serious injury can occur!■
When leaving the vehicle never leave people unattended in the car who
could, for example, lock the vehicle or release the brake - risk of accidents
and injury!

CAUTION■If water gets into the vehicle’s systems (e.g. the air intake system for the en-
gine) it can cause serious damage to the vehicle!■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.
Assist systems
General information
Introduction
WARNING■
The assistance systems serve merely to support the driver and do not re-
lieve the driver of responsibility for the operation of the vehicle.■
The increased safety as well as the increased occupant protection offered
by the assistance systems must not tempt you to take safety risks - there
is a risk of an accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only activate, deactivate and set the assistance systems to keep you fully
in control of the vehicle in every traffic situation - otherwise there is a risk
of an accident!

Traction control (TCS)
104
Electronic Differential Lock (EDL)

The brake and stabilisation systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 31, Warning lights .
103Assist systems
WARNINGThe general information relating to the use of assistance systems must be
observed » page 103, in section Introduction .
Stability Control (ESC)
Read and observe
on page 104 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehiclestarts to skid) by braking individual wheels to maintain the desired direction.
If there is a TCS intervention, the indicator light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 104 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres-
sure on the brake pedal.
Engine drag torque control (MSR)
Read and observe
on page 104 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
Traction control (TCS)
Read and observe
on page 104 first.
TCS prevents the spinning of the wheels on the drive axle. TCS reduces the
drive power transmitted to the wheels that are spinning. Thus, for example,
driving on road surfaces with low grip is made easier.
If there is a TCS intervention, the warning light flashes in the instrument
cluster.
Electronic Differential Lock (EDL)
Read and observe
on page 104 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes a spinning wheel if required and transfers the drive power force to the
other drive wheel. Driving becomes easier on road surfaces with different trac-
tion under each wheel of the driven axle.
The EDL switches off automatically in order to avoid excessive heat generation
on the brake of the wheel being braked. Once the brakes have cooled down,
there is an automatic re-activation of EDL.
Brake Assist (HBA)
Read and observe
on page 104 first.
HBA increases the braking effect and helps to shorten the braking distance.The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is re-
leased.
Hill Start Assist (HHC)
Read and observe
on page 104 first.
When moving off on a gradient, HHC allows you to move your foot from thebrake pedal to the accelerator pedal without the vehicle rolling downhill.
The vehicle is braked by the system for about 2 seconds after releasing the
brake pedal.
The HHC is active on gradients upwards up 5 % if the driver door is closed. HHC
is always only active on slopes when in forward or reverse start off.

/ Increase speedCLaunch control / reduce speeda)
If no speed is set the current speed is adopted.
Once the controls are activated, the CCS maintains the vehicle at the set
speed; the indicator light
lights up in the instrument cluster.
After the interruption in control, the stored speed can be resumed by pressing
the
B
button.
Controls are automatically interrupted if any of the following occur.
▶ By pressing the brake or clutch pedal.
▶ When one of the brake assist systems (e.g. ESC) intervenes.
▶ Through an airbag deployment.
WARNING■ Always deactivate the cruise control system after use to prevent the sys-
tem being switched on unintentionally.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.
Note
During control, speed can be increased by pressing the accelerator pedal. Re-
leasing the accelerator pedal will cause the speed to drop again to the set
speed.

City Safe Drive (hereinafter referred to as: the system) monitors the traffic sit-
uation ahead of the vehicle. If the system detects a risk of collision with an ob-
stacle ahead of the vehicle, then automatic braking is applied. The risk of a col-
lision is thus reduced and the consequences of an impact are minimized.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 103, in section Introduction .■
The system does not respond to crossing or oncoming objects.
CAUTION
The system can slow down the vehicle to a standstill. If the vehicle continues
to roll forward after stopping, then it should be stopped with the footbrake.

Laser sensor/detection range
Read and observe
and on page 107 first.
By means of a laser sensor » Fig. 128 -
the system registers traffic situations
ahead of the vehicle up to a distance of about 10 metres » Fig. 128 -
.
The system interventions take place when a risk of collision is detected as fol- lows.
▶ The brake system is prepared for an emergency stop.
▶ If the driver fails to respond to a detected danger, an automatic braking ac-
tion is performed.
The system can intervene if the following basic conditions apply. The engine is running.
The system is activated.
The vehicle speed is about 5-30 km/h.
The field of view of the laser sensor is not impaired.
107Assist systems
The system can, for example, be affected in the following situations or not
be available. ▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
▶ Driving around “sharp” bends.
▶ When fully pressing down the accelerator pedal.
▶ When the laser sensor is dirty or obscured.
▶ When the vehicles are very dirty and have a low level of reflection.
If the system is not available or there is a system malfunction, the message
and the warning light appears on the display of the instrument cluster
flashes in a slow sequence.WARNINGDo not cover the windscreen in the area of the laser sensor. This can lead
to impaired function of the sensor - risk of accidents!WARNINGThe laser beam from the laser sensor can cause serious eye injuries. The la-
ser beam is not visible to the human eye.■
Never use optical devices, e.g. a range-finder camera or magnifying glass
to look into the laser sensor.
■
The laser beam can also be active when the system is disabled or is not
available.
CAUTION
■ Remove any snow from the windscreen in the area of the laser sensor using
a hand brush and any ice with a solvent-free de-icing spray.■
If the laser sensor range on the windscreen has scratches, cracks, etc., re-
place the windscreen.
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.■
Automatic braking interventions by the emergency brake function can be ter-
minated by pressing the clutch or the accelerator or by moving the steering
wheel.
