202Driving and operatingActivation
If the system is activated, the LED in
the button Ó is not illuminated. To
activate the system when the system
is deactivated, press Ó.
The system is operational at vehicle
speeds between 65 km/h and
180 km/h and if lane markings are
detectable. The driver must hold the
steering wheel with both hands. The Electronic Stability Control system
must be activated.
The control indicator a flashes
yellow during trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, he can
prevent the correction by keeping a
firm grip on the steering wheel, e.g.
during an avoiding manoeuvre. The correction is interrupted if the turn
lights are operated.
There is no correction triggered when
the turn lights are operated and
during a few seconds after turn lights
have been switched off.
If the system detects that the driver is not holding the steering wheel firmly
enough during an automatic
correction of trajectory, it interrupts
the correction. A warning message in
the Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.
If the side blind spot alert is activated
and the driver is about to change the
lane, the system corrects the
trajectory of the vehicle despite the
activation of the turn lights if another
vehicle is detected in the side blind
spot zone.Deactivation
To deactivate the system, press and
hold Ó. Deactivation of the system is
confirmed by the illuminated LED in
the button. In the Driver Information
Centre solid grey lines are displayed.
Recommended deactivationIt is recommended to deactivate the
system in the following situations:
● Road surface in poor condition
● Unfavourable climatic conditions
● Slippery surfaces, e.g., ice
The system is not designed for driving
in the following situations:
● Driving on a speed circuit
● Driving with a trailer
● Driving on a rolling stand
● Driving on unstable surfaces
Driving and operating203Fault
In the event of a fault, a and H
appear in the instrument panel,
accompanied by a display message
and a warning chime. Contact a
dealer or a qualified workshop to have the system checked.
System limitations The system performance may be
affected by:
● windscreen not clean or affected by foreign objects, e.g. stickers
● close vehicles ahead
● banked roads
● narrow, winding or hilly roads
● road edges
● sudden lighting changes
● adverse environmental conditions, e.g. heavy rain or
snow
● vehicle modifications, e.g. tyresSwitch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the
vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
The system includes a driving time
alert combined with driver drowsiness detection.
9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling tired or at least every two hours.
Do not take the steering wheel
when feeling tired.

Vehicle care233The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
10 kPa for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Tyre deflation detectionsystem
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator w illuminates, a warning
chime is given and a warning
message is displayed in the Driver
Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 108.After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact 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:
234Vehicle care1. Always ensure that all four tyreshave correct tyre pressure
3 265.
2. Apply parking brake.
3. Initialise the deflation detection system: If the vehicle has a
graphic info display, press F for
three seconds. If the vehicle has a
colour info display, the
initialisation is done in the vehicle
personalisation 3 118.
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 depthCheck 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.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Vehicle care249Ice residues, pollution and continuous
wiping on dry windows will damage or
even destroy the wiper blades.
Glass panel Never clean with solvents or abrasive
agents, fuels, aggressive media e.g.
paint cleaner, acetone-containing
solutions, acidic or highly alkaline
media or abrasive pads.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check the underbody and have it waxed if
necessary.
Bitumen / rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.
Interior care
Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
