- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be
scal­

ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children - risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off- risk of injury!
Brake fluid
© CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system - risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­

tance.

- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­

pected.
This applies particularly if
you
drive
into a colder climate zone.
-To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­

ble.
In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by
a
qualified
workshop
^A-

The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Explanation of warnings on vehicle battery:

m

Wear safety glasses!
Battery acid is extremely corrosive. Wear
protective gloves and safety glasses.

A

Keep open flames, sparks, uncovered
Lights and lit cigarettes away from the
battery!
A highly explosive mixture of gases may

~\
be given off when the battery is under
charge!
Keep children away from batteries and
battery
acid.

A WARNING
Any work on the batteries and electrical sys­
tem in your vehicLe entails a risk of injury and
chemical burns in addition to danger of
acci­

dent or fire. For this reason, you must have
the work carried out by a qualified workshop.

If the car is left standing for long periods,
protect the battery from frost. The battery
will be damaged irreparably if it is allowed to
freeze

Vehicle battery

The
term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
If the vehicle is not used for long periods
If
you
do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are

using.
This limits the amount of power consumed
and helps to ensure reliable starting even after a
long period
^>page
149. Certain convenience fea­

tures,
such as interior lighting or electric seat ad­
justment, may not be available. These functions
will be restored when you switch on the ignition
and start the engine.
Even though some systems are deactivated auto­
matically, certain electrical equipment continues
to draw current even when the ignition is off. If
the vehicLe is left standing for long periods, this
can result in total battery discharge. If the
vehi­

cle battery is allowed to discharge completely, an
internal
chemicaL
reaction damages the battery
irreparably. To avoid this, the vehicle battery
should be recharged at Least once a month

^>page
303. PLease contact a qualified workshop
if
you
have any questions.
Winter conditions
Cold weather is very hard on the vehicle battery.
The starting capacity may be reduced as a result.
For this reason, you should have the vehicle bat­
tery checked by
a
qualified workshop before the
start of winter.

-The anti-freeze concentration must be
matched to the climate of the country in
which you are driving. If the concentration
is too
high,
damage to the car may result.
- Never put in radiator anti-freeze or other
additives.
- Never use washer fluid which contains paint
thinners or solvents as it can damage the
paintwork.
Service interval display

The
service interval display detects when the
next
service
is due
for
your vehicle.
There are two service interval dispLay levels:
- Inspection or oil change reminder: After a cer­
tain mileage, a service reminder will appear in
the instrument cluster dispLay each time the ig­
nition is switched on/off. The distance or time
remaining will be shown briefly.
- Inspection or oil change due: When your
vehi­

cle is due for an inspection, oil change or
both,

the corresponding reminder Inspection
due!,

Oil change due! or Oil change and inspection

due!
will appear briefly after you switch the ig­
nition on/off.
Checking the service intervals
On the infotainment system, you can look up the
distance and time remaining until the next oil
change or next service inspection. Select the
fol­

lowing on the infotainment system:

Service intervals.

Applies
to: vehicles with flexible oil change service
You cannot check the service interval on a new
vehicle until it has been driven for about 500 km.
Qualified workshops reset the service interval af­
ter the oil is changed. The distance to the next oil
change is initially displayed based on the driving
profile prior to the oil change. Your own personal
driving profile is used subsequently to calculate
the remaining distance. Frequent cold starts or
short trips place extra demands on the engine oil
with the result that the oil has to be changed
more often.
Resetting the display
Your qualified workshop resets the service inter­
val display after each service.
It is very important that you reset the oil change
dispLay if
you
change the oil yourself. The
next
oil
change will be due after
a
fixed service interval.

(J) CAUTION

- Do not reset the oil change interval display
unless you have changed the oil.
- Keeping to the correct service intervals is
crucial for the operation, service life and re­
sidual value of the vehicle (and especially
for the life of the engine). Services must al­
ways be carried out promptly, even if the
mileage is Low.

Jump-starting
Before starting the engine
If
necessary,
the engine can be started by con­
necting it to the battery of another vehicle.
If the engine fails to start because of
a
dis­
charged battery, the vehicle battery can be
con­

nected to the battery of another vehicle to start
the engine. Suitable jump leads are required.
Both vehicle batteries must be rated at 12 V. The
capacity (Ah) of the booster battery should not
be significantly lower than that of the discharged
battery.
Jump leads
The jump Leads must be heavy enough to carry
the starter current. Refer to the details given by
the manufacturer.
Only
use
jump leads with insulated battery
clamps.
Positive cable - usually red.
Negative cable - usually black.
WARNING
- When it is discharged the vehicle battery
can freeze at temperatures around 0°C. A
frozen vehicle battery must first be thawed
out before connecting the jump leads - risk
of explosion and chemical burns! After
jump-starting the vehicle, drive to a quali­
fied workshop without delay and have the
vehicle battery checked.
- The engine compartment is a potentially
hazardous area and working here can lead
to serious injuries. Before carrying out any
work in the engine compartment please
read and observe the warnings
*page
295.
- Incorrect handling of the jump leads may
result in the vehicLe battery exploding (risk
of serious injury). Please observe the follow­
ing rules to minimise the risk of injury:
- The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive terminal
must not touch metal parts of the vehicle:
this can cause short circuiting.
- Position the jump leads in such a way that
they cannot come into contact with any
moving parts in the engine compartment.
- Do not lean over the vehicle battery - risk of
chemical burns!
- The screw plugs on the battery cells must be
screwed in firmly.

- Keep sparks, flame and lit cigarettes away
from vehicle batteries: the gases given off
can cause an explosion.
- Do not attach the negative cable to parts of
the fuel system or to the brake pipes.
© CAUTION
- The vehicles must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected and
the boosting battery could be discharged.
- If the jump leads are not connected correct­
ly this can result in serious damage to the
electrical system of the vehicle.
- The discharged vehicle battery must be
properly connected to the vehicle's electri­
cal system.
- Please note that the method described
be­

low for connecting the leads is intended for
jump-starting your vehicle. If jump-starting
another vehicle, you should not connect the
negative lead (-) to the negative terminal of
the discharged battery, but directly to the
engine block or
a
solid metal part bolted to
the engine block. If the battery of the other
vehicle does not have a gas vent, there is a
risk that
a
mixture of oxygen and hydrogen
gas can accumulate and cause an explosion.

Tow-
start
ing / towing
away
General notes
Some experience is required to tow or tow-start a
vehicle, especially when using a tow-rope. Both
drivers should be familiar with the technique re­
quired for towing. Inexperienced drivers should
not attempt to tow-start or tow away another ve­

hicle.

Do not pull too hard with the towing vehicle and
take care to avoid jerking the tow-rope. When
towing off-road, there is aLways a risk that the
anchorage points may be overloaded.
Tow-bar / tow-rope
It is easier and safer to tow the vehicle with a
tow-bar. You should only use a tow-rope if you do
not have a tow-bar. It is advisable to use a tow-
rope made of elastic synthetic fibre or similarly
elastic material.
Notes on towing vehicles
The vehicle can be towed with a tow-bar or tow-

rope.
When the engine is not running, the
gear­

box will not be adequately lubricated if the
fol­

lowing speed/distance restrictions are not ob­

served:

- The vehicle must not be towed faster than
50 km/h.
- The vehicle must not be towed further than
50 km. •
