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
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, 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.130Driving

OperationFig. 164
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 motor is automatically started as soon as the accelerator pedal is de-
pressed or, if the Auto Hold function is deactivated, when 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. 164 .
The engine is switched off automatically; when moving off, the ignition
process will be initiated automatically.
The engine is not switched off automatically.
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 (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.
■
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

Electric parking brake
133
Parking
134WARNING■ Greater physical effort is required for braking 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 could then start to move –
risk of accident!
■
Observe the recommendations on the new brake pads » page 139, New
brake pads .
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 132 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. 
132Driving

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 to be 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 33,
 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.

WARNING■ The emergency brake is to be used only in an emergency when the vehi-
cle cannot be stopped with the brake pedal.■
When stopping and parking, the parking brake should always be on, oth-
erwise the vehicle could move off - there is the risk of an accident!
■
Do not place any objects in the recessed grip for the finger of the parking
brake key. The object could get into the space below the key and prevent
the operation of the parking brake!
Note
■ If the vehicle battery is discharged, it is not possible to release the parking
brake. First connect the vehicle first to a power source, such as the battery of

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 171, 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 171 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.
136Driving

Note■It may be beneficial, for example, when travelling downhill, to use manual
shifting of gears. Shifting to a lower gear reduces the load on the brakes and
hence the wear of the brakes » page 132.■
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached.
■
If a lower gear is selected, the gearbox does not shift down until there is no
risk of the engine over revving.

The 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 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 must firstly be “run in”, as they do not offer optimal grip at first.
Therefore, 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.
Therefore, 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 42.
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.
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 217.
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
Only turn on electrical consumers (e.g. seat, window and mirror heating and
the like) 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 » Owner´s Manual In-
fotainment , chapter CAR - Vehicle settings .
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 on if the windows are open.139Starting-off and Driving

If the functioning of the blinds is impaired and the vehicle reaches a speed of
about 150 km/h, the following message appears in the display of the instru-
ment cluster.Error: radiator shutter. Function restricted.RADIATOR SHUTTER RESTRICT_
After displaying the above message, the speed of the vehicle is automatically
limited to about 170 km/h.
If this message appears in the winter, the cause may be ice or snow caught up
in the blinds. After the ice or snow has thawed, the blinds are functional again.
If the impairment not due to ice or snow, then assistance from a specialist
should be sought.

This section of the manual contains important information on preventing dam-
age to the vehicle while driving.
Driving Tips
Only drive on such roads and in such terrain, which match the vehicle parame-
ters » page 246 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.
WARNING■ Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the vehicle can get damaged.■
Any objects that get trapped under the vehicle floor must be removed as
soon as possible. These objects can damage the fuel lines, the brake system,
seals and other parts of the vehicle.
■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.
Driving through water
Fig. 173
Maximum permissible water lev-
el when driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads).
›
Therefore determine the depth of the water before driving through bodies of
water.
The water level must not reach above the web of the lower beam » Fig. 173.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle which can
cause water to penetrate into the air induction system of the engine or into
other parts of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ Should water penetrate into the intake system of the engine, there is a
threat of serious damage being incurred by the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmission can be severely damaged. 
