Different dipsticks are used
depending on engine variant.
When the engine oil level has
dropped to the MIN mark, top-up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
On some engines, a funnel is needed to top-up engine oil.
The funnel is located on the right side storage in the load compartment.
Use the funnel to fill in the engine oil
into the engine oil opening.
After topping-up, put the funnel into the plastic bag and stow it in thestorage compartment.
Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 285.
Fit the cap on straight and tighten it.

Vehicle care225Engine coolantThe coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37°C.Caution
Only use approved antifreeze.
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
filling line mark. Top up if the level is
low.
9 Warning
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.
Engine B16DTH: After starting the
engine, set the heating to warmest
temperature and the fan speed to at
least first level for approx. 5 minutes.
This will ensure that the air within the cooling system escapes.
Have the coolant concentration
checked and have the cause of the
coolant loss remedied by a workshop.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.

The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.

Vehicle battery Vehicles without stop-start system
will be equipped with a lead acid
battery. Vehicles with stop-start
system will be equipped with an
AGM battery which is not a lead acid
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
4 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.
Vehicle battery discharge protection
3 147.
Replacing the vehicle battery
Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation 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.
Only use vehicle batteries that allow
the fuse box to be mounted above the
vehicle battery.
In vehicles with stop-start system, be
sure to have the AGM (Absorptive
Glass Mat) battery replaced with an
AGM battery again.

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 enginefails to start, seek the assistance of a
workshop.

Fuses
Data on the replacement fuse must
match the data on the defective fuse.
There are three fuse boxes in the
vehicle:
■ in the front left of the engine compartment
■ in left-hand drive vehicles, in the interior behind the storage
compartment, or, in right-hand
drive vehicles, behind the glovebox
■ behind a cover on the left side of the
load compartment
Before replacing a fuse, turn off the
respective switch and the ignition.

There are different kinds of fuses in
the vehicle.
Depending on the type of fuse, a
blown fuse can be recognized by its
melted wire. Do not replace the fuse until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Fuse extractor A fuse extractor may be located in the fuse box in the engine compartment.
Place the fuse extractor on the
various types of fuse from the top or
side, and withdraw fuse.
