Switch 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.
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.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 107.
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert The driver gets notified by a pop-up
reminder symbol € in the Driver
Information Centre simultaneously with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 40 mph. The alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
Driving and operating199
A portable charge cord used to
charge the vehicle high voltage
battery is stored under the rear floor
storage cover in the load
compartment 3 194 . The charge cord
is compatible with the domestic
electrical outlet of the respective
country. It includes a control box with
charging status indicators.
If the vehicle is to be used abroad,
check whether the wall plug of the
charge cord is compatible with the
local electrical outlets. If a different
charge cord is needed, consult a
workshop.
Important information about
portable electric vehicle charging
● Charging an electric vehicle can stress a building's electrical
system more than a typical
household appliance.
● Before you plug in to any electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions and
protection devices) for heavy-
duty service at a 10 A continuous
load.
● Electrical outlets may wear out with normal usage or be
damaged over time, making them unsuitable for electric vehicle
charging.
● Check the electrical outlet / plug while charging and discontinue
use if the electrical outlet / plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.● When outdoors, plug into an electrical outlet that is weather-
proof while in use.
● Mount the charging cord to reduce strain on the electricaloutlet / plug.9 Warning
Improper use of portable electric
vehicle charge cords may cause a fire, electrical shock, or burns, and
may result in damage to property,
serious injury, or death.
● Do not use extension cords, multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
● Do not use an electrical socket that is worn or damaged, or onethat will not hold the plug firmly
in place.
● Do not immerse the charging chord into any liquid.
206Driving and operatingreduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 256.
Vertical coupling load The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (70 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum vertical
coupling load, especially in the case
of heavy trailers. The vertical coupling
load should never fall below 25 kg.Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
60 kg , the gross vehicle weight rating
must not be exceeded. If the
permissible rear axle load is
exceeded, a maximum speed of
60 mph applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Fitting the coupling ball bar
Disengage and fold down the socket. Remove the sealing plug from the
opening for the coupling ball bar and
stow it.
214Vehicle careClosing
Before closing the bonnet, press the
support into the holder.
Lower the bonnet and let it fall into the latch from a low height (20-25 cm).
Check that the bonnet is engaged.Caution
Do not press the bonnet into the
latch to avoid dents.
Engine oil
Check the engine oil level manually
on a regular basis to prevent damage
to the engine. Ensure that the correct
specification of engine oil is used.
Recommended fluids and lubricants
3 254.
The maximum engine oil
consumption is 0.6 l per 600 miles.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 min.
Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality engine oil in
the engine.
Pull out the dipstick, wipe it clean, reinsert it fully, pull out and read the
engine oil level.
When the engine oil level has
dropped to the MIN mark, top up the
engine oil.
Different dipsticks are used
depending on engine variant.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out. If the
engine oil exceeds the maximum
level, do not start the vehicle and
contact a workshop.

Vehicle care231Directional tyresDirectional 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 3 266.
The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
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:
1. Identify the engine identifier code.
Engine data 3 260.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 266.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.The 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
234Vehicle careWheel coversWheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
