240Vehicle careRepeat the checking procedure
once more after driving further
10 km but no more than ten
minutes to check that there is no
more loss of pressure.
If the tyre pressure has fallen
below 150 kPa (1.5 bar), the
vehicle must not be used. Seek
the assistance of a workshop.
17. Stow away tyre repair kit in load compartment.
Note
The driving characteristics of the
repaired tyre are severely affected, therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least 30 min.
The built-in safety valve opens at a
pressure of 700 kPa (7 bar).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
Wheel changing
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 orP .
● 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-upvehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Vehicle care243●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 3 241.
● 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.9Warning

9Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Disengage wheel bolt caps with the wheel bolt cover remover.

Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with the wheel bolt cover remover.
2. Fold out the wheel wrench and install ensuring that it locates
246Vehicle care● The vehicles must not come intocontact with each other during
the jump starting process.
● Apply the parking brake, transmission in neutral,
automatic transmission in P.
Open the positive terminal protection
caps of both vehicle batteries.
Lead connection order: 1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
3. Connect the black lead to the negative terminal of the boosterbattery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than 15 s at an interval of 1 min.
3. Allow both engines to idle for approx. three minutes with the
leads connected.
4. Switch on electrical consumers e.g. headlights, heated rear
window of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Wrap a cloth around the tip of a flat
screwdriver, for example, to prevent
paint damage. Insert the screwdriverin the slot at the lower part of the cap.
Release the cap carefully.
The towing eye is stowed with the vehicle tools 3 232.
Vehicle care247
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 183, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Never tow a vehicle equipped with All Wheel Drive (AWD) with the
front or rear tyres on the road. If
you tow a vehicle equipped with
AWD while the front or rear tyres
are rolling on the road, the drive
system in the vehicle could be
severely damaged. When towing
vehicles equipped with AWD, all
four tyres must not be in contact
with the road.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 80 km/h nor further than 100 km. In all other cases
and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
Insert cap with the flange into the
recess and fix cap by pushing.
Vehicle care251For 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 aweak soap solution.Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water
or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could
damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.
Floor mats9 Warning
If a floor mat has the wrong size or
is not properly installed, it can
interfere with the accelerator pedal
and/or brake pedal, what can
cause unintended acceleration
and/or increased stopping
distance which can cause a crash and injury.
Use the following guidelines for
proper floor mat usage.
● The original equipped floor mats were designed for your vehicle.
Have damaged floor mats only
258Service and maintenancefor 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 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 3 155.
274Customer informationDepending on technical equipment
level, 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 when 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 which is read out,
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.Comfort and infotainment
functions
Comfort settings and custom settingscan be stored in the vehicle and
changed or reset at any time.
Depending on the equipment level in
question, these include
● seat and steering wheel position settings
● chassis and air conditioning settings
● custom settings such as interior lighting
You can input your own data in the
infotainment functions for your
vehicle as part of the selected
features.
Depending on the equipment level in
question, these include
● multimedia data such as music, videos or photos for playback in
an integrated multimedia system
● address book data for use with an
integrated hands-free system or an integrated navigation system
