Accessories and vehicle
modifications
We recommend the use of genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or
guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve the rubber seals.
■ Fill up fuel tank completely.
■ Change the engine oil.
■ Drain the washer fluid reservoir.
■ Check the coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park the vehicle in a dry, well ventilated place. Engage first orreverse gear or set selector lever to P . Prevent the vehicle from rolling.
■ Do not apply the parking brake.
Vehicle care225
Power steering fluid level normally
does not have to be checked. If an
unusual noise sounds during steering or the power steering reacts
unusually, seek the assistance of a
workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of windscreen
washer fluid which contains
antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Brakes
In the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
226Vehicle care
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 268.
Vehicle battery Vehicles without stop-start system
will be equipped with a lead acid
battery. Vehicles with stop-start
system will be equipped with an
AGM battery which is not a lead acid
battery.
The vehicle battery is maintenance-
free, provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
The anti-theft alarm siren must be
deactivated as follows: Switch the ignition on then off, disconnect the
vehicle's battery within 15 seconds.
Vehicle battery discharge protection
3 146.
Replacing the vehicle battery Notice
Any deviation from the instructions
given in this section may lead to
temporary deactivation of the stop-
start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.
Only use vehicle batteries that allow
the fuse box to be mounted above the
vehicle battery.
In vehicles with stop-start system, be
sure to have the AGM (Absorptive
Glass Mat) battery replaced with an
AGM battery again.
Service and maintenance269
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 272.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 272.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.AdBlue
Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 163.
