System conditioned automatic start-upRead and observe
on page 124 first.
When the engine is off, the system can automatically start the engine before
the desired journey continues. The possible reasons for this are, for example:
› The vehicle has begun to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

Fatigue detection (break recommendation)
Introduction
This chapter contains information on the following subjects:
Function
126
Information messages
127
The fatigue detection system (hereinafter referred to only as system) recom-
mends the driver taking a break from driving when, because of the driver's
steering behaviour, driver fatigue can be detected.
WARNING■ For the driving ability is always the driver's responsibility. Never drive if
you feel tired.■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Function
Read and observe
on page 126 first.
From the start of the journey, the system evaluates steering behaviour. If,
while driving, there have been changes in the steering behaviours that are
evaluated by the system as indicating possible fatigue, a break recommenda-
tion is issued.
126Driving
Page 130 of 216

The system evaluates steering behaviour and recommends a break at speeds
of 65 - 200 km/h.
The system detects a break from driving when one of the following condi-
tions is met.
› The vehicle is stopped and the ignition switched off.
› The vehicle is stopped, the seat belt removed and the driver's door opened.
› The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
The system can be activated/deactivated in the Infotainment » operating in-
structions for Infotainment , chapter Vehicle settings (CAR button) .

Save tyre pressure values and infotainment display
128
Save tyre pressure values by pressing a button
128
The tyre pressure monitoring function monitors (hereinafter referred to only as
a system) the tyre pressure while driving.
When changing the tyre inflation pressure, the warning light illuminates in
the instrument cluster and an audible signal is heard.
Information on the procedure for the indication of change in tyre pressure val- ues » page 37 .
The system can only function properly if the tyres have the prescribed tyre
pressure and this pressure values are stored in the system.
WARNING■ The correct tyre pressure values is always the driver's responsibility. The
tyre pressure should be checked regularly » page 162.■
The system cannot warn in case of very rapid loss of tyre pressure, e.g. in
the event of a sudden puncture.
Save tyre pressure values
Read and observe
on page 127 first.
The tyre pressure valuesare always stored in the system, if one of the follow-
ing events is present.
› Change of tyre pressure values.
› Change one or more wheels.
› Change in position of a wheel on the vehicle.
› The warning light
in the instrument cluster.
The storage of the tyre pressure values depends on equipment, either in the
infotainment or by pressing a button.
WARNINGBefore storing the tyre pressures they must be inflated to the specified in-
flation pressure » page 162. If incorrect pressure values are storedthe sys-
tem may not warn even with a tyre pressure that is too low.
CAUTION
The tyre pressure values should be stored every 10 000 km or once a year to
ensure proper system function.127Assist systems

WARNING■
Check that the ball head is seated correctly and is secured in the mount-
ing recess before starting any journey.■
Do not use the ball head if it is not correctly inserted in the mounting re-
cess.
■
Do not use the towing equipment if it is damaged or incomplete.
■
Do not modify or adapt the towing equipment in any way.
■
Never release the ball head while the trailer is still coupled.
■
Keep the mounting recess of the towing equipment clean at all times.
Such dirt prevents the ball head from being attached securely.
CAUTION
■ Take care with the tow bar - there is a risk of damaging the paint on the
bumper.■
When the ball rod is removed, always place the cover onto the mounting re-
cess - there is a danger of soiling the mounting recess.

operating lever
C
downwards as far as it can go. Clean the contact surfaces
on the tow bar and the mounting recess.
WARNING■ Carefully remove the cap for the mounting recess B - there is a risk of
hand injury.■
Keep your hands outside the operating lever's range of motion when at-
taching the ball head – there is a risk of finger injury.
■
Never attempt to pull the operating lever upwards forcibly to turn the
key. Doing so would mean the ball head is not attached correctly.
CAUTION
Remove the cover A from the rear bumper with care - there is a risk of paint
damage to the bumper and the cap.
Note
Store the caps A and B » Fig. 133 in a suitable place in the luggage compart-
ment after removal.

WARNINGNever allow the ball head to remain unsecured in the boot. This could
cause damage to the boot upon sudden braking, and could put the safety
of the occupants at risk.CAUTION■ If the operating lever B is held firm and not pushed downwards as far as it
can go, it will go back up after the ball head is removed and will not latch into
the ready position. The ball head then needs to be brought into this position
before the next time it is fitted » page 130, Adjusting the ready position .■
Place the tow bar in the standby position, with the key upwards, and store in
the box - otherwise there is a risk of damage to the key!
■
Do not use excessive force when handling the operating lever (e.g. do not
step on it).
Note
Clean any dirt from the ball head before stowing it away in the box with the
vehicle tool kit.

An accessory can be mounted on the ball head of the towing device (such as a
bike carrier).
If this accessory is used, the maximum permissible protrusion of the towing
device ball head and the permissible gross vehicle weight of the accessory in-
cluding load is to be observed.
The maximum permissible protrusion for the ball head of the towing device is
