Vehicle care215Engine coolant
The factory filled coolant provides
freeze protection down to approx.
-37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 254.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
MIN mark. Top up if the level is low.
9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.

216Vehicle careCaution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 254.
Brakes In the event of minimum thickness of
the 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 fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe DANGER and MAX marks.
If fluid level is below DANGER seek
the assistance of a workshop.
Brake and clutch fluid 3 254.
Vehicle 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
four 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.
Battery discharge protection 3 121.
Replacing the vehicle battery Notice
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
Page 219 of 283

Vehicle care217When 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.
Ensure that the battery is always replaced by the same type of battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 138.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.
Jump starting 3 242.
Discharge protection
Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.
When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, such as
the air conditioning, the heated rear
window, heated steering wheel, etc.
The deactivated functions are
reactivated automatically as soon as
conditions permit.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by
an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Power outlet
The power outlets are deactivated in
the event of low vehicle battery
voltage.Warning label
Meaning of symbols:
● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● Keep the vehicle battery out of reach of children.

218Vehicle care● See the Owner's Manual forfurther information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Power saving mode This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Changing into power saving mode
When power saving mode is
activated, a message appears in the
Driver Information Centre.
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.Deactivating power saving mode
Power saving mode is deactivated
automatically when the engine is
restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes
Heating functionalities Notice
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.Diesel fuel system bleeding
If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of 40 seconds. Repeat this process after
no less than 5 seconds. If the engine fails to start, seek the assistance of a
workshop.
