Information messages
126
The START STOP system (hereinafter referred to as the system) reduces CO 2
emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
or is at a standstill (e.g. at the traffic lights), it turns off the engine and starts it
again when moving 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.124Driving

OperationFig. 145
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.
Conditions for the system function
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. 145 .
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.
Reasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, 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 interior 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 » Owner´s Manual Infotainment , chapter CAR - vehicle set-
tings .
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.
■
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.

Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information on braking
126
Handbrake
127
Parking
128WARNING■ Greater physical effort for braking is required when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle might then move off – risk of accident!
■
Observe the recommendations on the new brake pads » page 132.
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 126 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
126Driving

Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times »
.
Corrosion
Corrosion on the brake discs and dirt on the bake pads 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 »
.
Long or steep slopes
Before travelling a long distance with a steep gradient, reduce speed and shift
into the next lowest gear. As a result, the braking effect of the engine will be
used, reducing the load on the brakes. Any additional braking should be com-
pleted intermittently, not continuously.
Emergency brake display
If the brakes are applied in full and the vehicle systems evaluate the situation
as dangerous for the traffic following behind, the brake light flashes automati-
cally.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af-
ter accelerating or driving off again.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately, as you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 32,
Brake sys-
tem .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
WARNINGOnly apply the brakes 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.

D/S - mode for driving forward (Normal program) / mode for driving
forward (Sport program)
The system switches from one mode to the other by moving the selector lever
into the spring-loaded position
» Fig. 149 .
In mode D or S, the forward gears are shifted automatically depending on the
engine load, the operation of the accelerator pedal, the vehicle speed, and the
selected driving mode .
In mode S , the forward gears are shifted automatically up and down at high-
er engine speeds than in mode D.
If the Sport driving mode is selected with the engine running » page 157, Se-
lection of the driving mode (Driving Mode Selection) , the transmission is auto-
matically set in the S mode.
E – Economical driving mode
If the driving mode Eco or Individual (engine - Eco) » page 157 is selected and
the selection lever is in the setting D/S, the transmission is automatically set
to mode E. This mode cannot be selected with the selector lever.
In mode E , the forward gears are shifted automatically up and down at lower
engine speeds than in mode D.
