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.

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

›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!

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.
Operation

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.

Checking and refillingFig. 140
Coolant expansion reservoir
Read and observe and on page 124 first.
Check and refill coolant under the following conditions.The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm the result of the check may
be wrong).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks
A
and
B
» Fig. 140. If the coolant level is below the mark
B
, top up with coolant.
Refilling
The reservoir must always contain a small amount of coolant »
.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 140 .
If the specified coolant is not available, then refilling only with distilled or dem-
ineralised water, and get a specialist garage to correct the water-coolant addi-
tive mix as soon as possible.
CAUTION■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage! Stop driving! Switch off the engine and seek
assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 140 . The coolant could, when
heated, be expelled from the cooling system - risk of damage to the engine
parts.
■
If it is not possible to add coolant,
do not continue driving! Switch off the
engine and seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - risk of damage to the
cooling system and the engine.
■
If non-distilled (non-demineralised) water has been used to top up, the cool-
ant should be replaced by a specialist garage - risk of engine damage.
■
A loss of coolant indicates leaks in the cooling system - risk of engine dam-
age. Top up with coolant and then seek assistance from a specialist garage.
Note
If the coolant level is too low, a warning light lights up in the instrument clus-
ter » page 33 . We still recommend inspecting the coolant level directly at the
reservoir from time to time.
Brake fluid

Under no circumstances attempt to lift other vehicles or loads with it –
there is a risk of injury.■
Always stow the tool safely in the box and make sure that it is attached
with the belt to the spare wheel - otherwise it could cause injury to the oc-
cupants if breaking suddenly or colliding with another vehicle.
CAUTION
Screw the jack back to its starting position prior to putting it back in its box -
risk of damage to the box.
Note
The declaration of conformity is included with the jack or the log folder.
Changing a wheel
Preliminary work
For safety's sake, the following instructions must be observed before
changing a wheel on the road.
›
As far as possible park the vehicle as far as possible away from the traffic
flow - choose a place with a flat and firm surface.
›
Switch off the engine.
›
For vehicles with manual transmission select 1st gear .
›
For vehicles with
automated transmission shift the lever to position D or R.
›
Firmly apply the handbrake.
›
Switch on the hazard warning lights and set up the warning triangle at the
prescribed distance.
›
Have all the occupants get out . The passengers should not stand on the
road while the wheel is being changed (they should remain behind a crash
barrier, for instance).
Changing a wheel
›
Take out the emergency or spare wheel » page 135.
›
Remove the full wheel trim » page 135 or caps » page 135 .
678›Loosen the wheel bolts
» page 136 » .›Jack up the vehicle until the wheel that needs changing, is clear of the
ground » page 136 .›
Unscrew the wheel bolts and place them on a clean surface (cloth, paper,
etc.).
›
Remove the wheel carefully.
›
Attach the spare wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
›
Tighten the wheel bolts opposite each other using the wheel wrench (“pull- ing crossways”) » page 136.
›
Replace the wheel trim » page 135 and caps » page 135 .
When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect » page 129 .
All bolts must be clean and must turn easily. If screws are corroded and diffi-
cult to move, these must be replaced.
WARNING■ Undo the wheel bolts just a little (about one turn), provided the vehicle
has not yet been jacked up. Otherwise the wheel could come loose and fall
off – risk of injury.■
Under no circumstances must the bolts be greased or oiled - cause an ac-
cident.
Subsequent steps
After changing the wheel, the following work must be carried out.
›
Stow the replaced wheel in the well under the floor covering of the luggage
compartment and secure it with a nut.
›
Stow the tool kit in the space provided and secure using the band.
›
Check tyre pressure on the mounted wheel and adjust if necessary and, with
vehicles with tyre pressure monitoring, save the tyre pressure values in the
system » page 109 .
›
Have the tightening torque of the wheel bolts checked as soon as possible.
The prescribed tightening torque is 110 Nm.
Replace the damaged wheel or consult a specialist garage about repair op-
tions.
