Driving and operating185Switching off the system
Turn to 0 to switch off the system. The
symbol 5 and a message are
displayed in the Driver Information
Centre.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that the
control of the vehicle can be lost.
● Do not use the system when the spare wheel is in use.
System limits9 Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● The control range is limited to a maximum deviation of 30 km/h
between the set speed and the
speed of the vehicle ahead.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles onlyat low speed.
● Do not use the adaptive cruise control when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
190Driving and operatingEmergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash. If the
vehicle comes to a complete stop,
automatic braking is maintained for
up to 2 seconds.
● Automatic transmission: If the vehicle comes to a completestop, keep the brake pedal
depressed to prevent the vehicle
from starting off again.
● Manual transmission: If the vehicle comes to a complete
stop, the engine may stall.
Operation of the function may be felt
by a slight vibration in the brake
pedal.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating
speed range and only responds to
detected vehicles and
pedestrians.
System limitations
In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is
limited:
● Driving on winding or hilly roads.
● Detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● Detecting a vehicle when weather limits visibility, such as infog, rain, or snow.
● Driving during nighttime.
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Complete attention is always required
while driving, and the driver should be ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when tyre chains are fitted
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera

4. a wheelbrace adapter for the security wheel bolts.
5. a towing eye.
Vehicles without spare wheel
The box contains a towing eye and a
tyre repair kit.
Tyre repair kit 3 241.
Vehicle care237Wheels and tyres
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
All tyre sizes are permitted as winter
tyres 3 271.Tyre designations

Choose a tyre appropriate for the
maximum speed of your vehicle. Refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents. Optional equipment
could reduce the maximum speed of
the vehicle.
Directional tyres
Directional tyres should be mounted
so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol (e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 271.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
Vehicle care239contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference
reference values:
1. Always ensure that all four tyres have correct tyre pressure
3 271.
2. Apply parking brake. 3. Start the initialisation procedure:
a) Vehicles without Infotainment
system: Press button q for 3
seconds. A chime confirms the
start.
b) Vehicles with Infotainment
system: Initialise the deflation
detection system in the vehicle
personalisation 3 124.
4. Reset is confirmed by pop-up indication.
After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when:
● Tyre pressure has been changed
● Load condition has been changed
● Wheels have been swapped or exchanged
The system will not warn
instantaneously on a tyre blow out or a rapid deflation. This is due to
required calculation time.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
Vehicle care241Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add
no more than 9 mm to the tyre tread
and the inboard sides (including chain lock).9 Warning
Damage may lead to tyre blowout.
Tyre chains are permitted on all tyres
sizes allowed for the vehicle.
Temporary spare wheel
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's sidewall cannot be repaired with the tyre repair kit.
9 Warning
Do not drive faster than 80 km/h.
Do not use for a lengthy period.
Steering and handling may be
affected.
In the case of a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is located in the tool
box underneath the left front seat.
Tool box 3 234.
1. Pull speed limit label from the tyre
repair kit and place it in driver's
visible area.
2. Pull the electrical cable and air hose out of the compartments on
the underside of the kit.
3. Turn selector A to the "sealant"
position. Check that switch B is in
position J.
Vehicle care2459Warning
Do not grease wheel bolts.
Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
125 Nm.
Tightening torque for steel wheels is
125 Nm.
Use the correct wheel bolts for the respective wheels.
Jacking positions The jacking positions shown refer tothe use of lifting arms and accessoryjacks used for changing winter /
summer tyres.
The rear arm position of the lifting
platform is centrically under the
relevant vehicle jacking point.
The front arm position of the lifting
platform is centrically under the
relevant vehicle jacking point.
Spare wheel The spare wheel is located in a holder
beneath the vehicle floor.
The tools are in a box in the left front
seat 3 234.
Use the jack only on the specific
jacking positions 3 244.
