Vehicle care217Caution
If driving with a temporary spare
wheel, active emergency braking
has to deactivated.
The temporary spare wheel is located in the load compartment beneath the
floor covering.
To remove: 1. Open the floor cover.
2. The temporary spare wheel is secured with a wing nut. Unscrew
nut and take out the spare wheel.
There is a box with tools in the
right wall of the load
compartment.
Vehicle tools 3 207.
3. When, after a wheel change, no wheel is placed in the spare wheel
well, fasten the wing nut and close the floor cover.
4. After a wheel change back to a full
size wheel, place the spare wheel
outside up in the well and secure
with the wing nut.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Fitting the spare wheel
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● If necessary, place a chock under
the wheel diagonally opposite the
wheel to be changed.● Apply the parking brake and engage first gear, reverse gear or
P .
● Remove the spare wheel.
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.

228Service and maintenanceGeneral informationService informationIn order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the
proper intervals as specified.
The detailed, up-to-date service
schedule for your vehicle is available
at the workshop.
Severe operating conditions exist if
one or more of the following
circumstances occur frequently: Cold starting, stop and go operation, e.g.
for taxis and police vehicles, trailer
operation, mountain driving, driving
on poor and sandy road surfaces,
increased air pollution, presence of
airborne sand and high dust content,
driving at high altitude and large
variations of temperature.
Under these severe operating
conditions, certain service work may
be required more frequently than the
regular service interval indicated inthe service display. Contact a
workshop for customised service
schedules.

230Service and maintenanceConfirmations
Confirmation of service is recorded in the Service and warranty booklet. The date and mileage is completed with the stamp
and signature of the servicing workshop.
Make sure that the Service and warranty booklet is completed correctly as continuous proof of service is essential if any warranty or goodwill claims are to be met, and is also a benefit when selling the vehicle.

Service and maintenance231Recommended fluids,
lubricants and parts
Recommended fluids and lubricants
Only use products that meet the
recommended specifications.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is
unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 235.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 235.
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 3 235.
Page 234 of 263

232Service and maintenanceAll 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. -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.
Washer fluid Use only washer fluid approved for
the vehicle to prevent damage of
wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.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.

252Customer informationOperating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, for example: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate, "seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient and is
not stored for longer than an
operational cycle, and only processed on board the vehicle itself. Often
control units include data storage
(including the vehicle key). This is
used to allow information to be
documented temporarily or
permanently on vehicle condition,
component stress, maintenance
requirements and technical events
and errors.Depending on technical equipment
levels, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used where necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
data from the vehicle. The same
applies to warranty work and quality
assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data read documents the
technical condition of the vehicle or
individual components and assists
with fault diagnosis, compliance with
warranty obligations and quality
improvement. This data, in particular
information on component stress,
technical events, operator errors and
other faults, is transmitted to the
manufacturer where appropriate,
together with the vehicle identification number. The manufacturer is also
subject to product liability. The
manufacturer potentially also uses
operating data from vehicles for
product recalls. This data can also be
used to check customer warranty and
guarantee claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.
