to the engine. Ensure that the correct
specification of oil is used.
Recommended fluids and lubricants
3 226.
The maximum engine oil
consumption is 0.6 litres per
1000 km.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least five minutes.
Pull out the dipstick, wipe it clean, reinsert it fully, pull out and read the
engine oil level.
When the engine oil level has
dropped to the MIN mark, top up the
engine oil.Different dipsticks are used
depending on engine variant.
We recommend the use of the same
grade of engine oil that was used at
last change.
Page 191 of 257

Vehicle care189The engine oil level must not exceed
the MAX mark on the dipstick.Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 238.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -37 °C.
Caution
Only use approved antifreeze.
Coolant and antifreeze 3 226.
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.

190Vehicle careCaution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 226.
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

corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
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 3 226.
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 3 119.
Disconnecting the battery
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: Switch the
ignition on then off, then disconnect
the vehicle's battery within
15 seconds.

Vehicle care191After having reconnected the battery
of a vehicle equipped with an anti-
theft alarm system, wait 10 minutes
until you start the engine.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance 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.
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 volts when using a battery
charger. Otherwise the vehicle
battery might be damaged.
