START-STOPsystem
Introduction
This chapter contains information on the following subjects:
Operation
88
Manually deactivating/activating the system
89The 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, while others are systemic and can neither be influenced nor identified.
For this reason, the system may react differently in situations which seem
identical from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even when it has previously been manually deactivated with the button).
Note
If the engine has stopped due to the system, the ignition remains switched on.
Operation
Fig. 106
Display
Vehicles with manual transmission
The engine is automatically switched off as 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 started as soon as the clutch pedal is depressed.
Vehicles with automatic transmission
The engine is automatically switched off as soon as the vehicle comes to a
halt and the brake pedal is operated.
The engine is automatically started as soon as the brake pedal is released.
88Driving
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 driving speed was higher than 4 km/h after the last stop.
No trailer or other accessory is connected to the trailer socket.
System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 106 .
The engine is switched off automatically; when moving off, the ignition
process will be initiated automatically.
The engine is not switched off automatically.
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.
More information about the current system status can be displayed on the In-
fotainment screen » Owner´s Manual - Infotainment .
If there is a system fault , the following message will appear in the display of
the instrument cluster. Seek help from a specialist garage.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 shut-down
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.
Manually deactivating/activating the system

To deactivate/activate the system, press the
button » Fig. 107 .
When the system is deactivated, the symbol
in the button lights up.
If the system is deactivated, it will be reactivated automatically after the igni-
tion has been switched off and on.
Note
If the system is deactivated when the engine is turned off automatically, then
the automatic start process takes place.
Brakes and parking
Introduction
This chapter contains information on the following subjects:
Handbrake
90
Parking
91
89Starting-off and Driving
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 30,
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!■
The clutch pedal must be actuated when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the functionality of the brake system may be impaired – risk of accident!
WARNING (Continued)■ 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
Fig. 108
Handbrake
Read and observe on page 90 first.
The handbrake secures the vehicle against unwanted movement when stop-
ping and parking.
Apply
›
Pull the handbrake lever firmly upwards.
Releasing
›
Pull the handbrake lever up slightly and at the same time push in the locking
button » Fig. 108 .
›
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.
90Driving
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
Read and observe
on page 90 first.
When stopping and parking, look for a place with a suitable surface » .
Only carry out the activities while parking in the specified order.
›
Bring the vehicle to a stop and depress the brake pedal.
›
Firmly apply the handbrake.
›
On vehicles with automatic transmission , place the selector lever in the P
position.
›
Switch off the engine.
›
For vehicles with manual transmission , select gear 1 or reverse gear R .
›
Release the brake pedal.
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!

The shift pattern
The gearshift pattern for the individual gear positions is shown on the gear
lever » Fig. 109 .
The gearshift indicator should be observed when changing gear » page 38.
Always depress the clutch pedal all the way down. This prevents uneven wear
to the clutch.
Engaging reverse gear
›
Stop the vehicle.
›
The clutch pedal must be fully depressed.
›
Switch the gear lever to N.
›
Push the shift lever downwards fully to the left and then forward into
R » Fig. 109 .
The reversing lights will come on once the reverse gear is engaged, provided
the ignition is on.
WARNINGNever engage reverse gear when driving – risk of accident!
CAUTION
If not in the process of changing gear, do not leave your hand on the gear shift
lever while driving. The pressure from the hand can cause the gear shift mech-
anism to wear excessively.
Pedals
The operation of the pedals must not be hindered under any circumstances!
91Starting-off and Driving
The following instructions must be observed if vehicle damage is to be avoided
when driving through water (e.g. flooded roads).›
Therefore, always determine the depth of the water before driving through
water. The water level must not go above the web of the lower beam
» Fig. 114 .
›
Drive at no more than walking pace, otherwise a wave may form in front of
the vehicle, which could cause the water to enter into the vehicle’s systems
(e.g. the air intake system for the engine).
›
Never stop in the water, do not reverse and do not switch the engine off.
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. A 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 only serve to support the driver and do not re-
lieve the driver of the responsibility for driving the vehicle.■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of 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 enable, disable or set the assistance systems so that you have the
car fully under control in every traffic situation - risk of accident!

96Driving
WARNINGThe general information relating to the use of assistance systems must be
observed » page 96, in section Introduction .
Stability Control (ESC)
Read and observe
on page 97 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehicle
starts to skid) by braking individual wheels to maintain the desired direction.
If there is a TCS intervention, the warning light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 97 first.
ABS prevents the wheels from locking when braking. Thereby, it helps 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 97 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)Fig. 115
Button for the TCS system
Read and observe on page 97 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the
drive power transmitted to the wheels in the case of slipping wheels. Thereby,
for example, driving on road surfaces with low grip is made easier.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
The deactivation/activation of TCS can be carried out, depending on equip-
ment, in one of the following ways. ▶ Infotainment » Owner's Manual - Infotainment .
▶ By pressing the
» Fig. 115 button.
With deactivation , the warning light
lights
up in the instrument cluster and
an appropriate message is displayed in the instrument cluster.
With activation , the warning light
is
extinguished and an appropriate mes-
sage is displayed in the instrument cluster.
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example. ▶ When driving with snow chains.
▶ When driving in deep snow or on a very loose surface.
▶ When “rocking a car free” when it has become stuck.

If, during the control, it is necessary to exceed the speed limit (e.g. to over-
take), the accelerator pedal must be pressed fully.
When exceeding the speed limit (e.g. driving down a hill), an acoustic signal
sounds and the warning light flashes in the instrument cluster.
The regulation is resumed once the speed has fallen below the set limit.
