the first switch off,

then start filling the tank with the fuel

pump nozzle again until it switches
off.

Tank fluid capacity
Fuel tank capacity approx. 35 ltrs.,
including a reserve of approx. 5 ltrs.

Danger of injury!
Petrol is highly inflammable.

Fire, naked flames and smoking are
therefore prohibited when handling
petrol.
Avoid allowing petrol to come into
contact with your skin or clothes. You
will damage your health if
your skin comes directly into contact

with petrol.

you inhale petrol vapours.

Danger of poisoning!
Keep children away from fuel. If

any fuel is swallowed, consult a doctor
immediately.

Environment!
Never allow fuel to spill over.

Never overfill the fuel tank.
Fuel that has spilled over onto the
ground pollutes the environment.

Fire hazard!
When topping up the engine oil,

take care to ensure that no oil is spilt
on any hot parts such as the exhaust
system or catalytic converter.
If this should however happen, the
engine must be thoroughly cleaned off
before you continue your journey. The
oil could otherwise ignite.

Routines 97

Engine oil level

Choosing the right type of oil
Use only oils approved by smart gmbh
(acc. to MB sheet 229.5). The MB sheet
number is marked on the oil containers. A
list of the approved engine oils can be
obtained from any smart center or
smart service.

>Important!
Do not use special additives. They may
lead to increased wear or engine damage.
A qualified specialist workshop such as a
smart center will be able to provide
further details.

Engine oil viscosity
The SAE class (viscosity) has to be chosen
in accordance with the average outside
air temperature for each current season.
Exact adherence to the SAE classes
according to the outside temperatures
would, however, necessitate frequent oil
changes. The temperature limits for the
SAE classes therefore should be viewed as
guidelines which can be temporarily
exceeded or undercut.

Environment!
One drop of oil will contaminate

1,000 litres of water.
Take care not to spill oil when topping
up. Spilled oil could seep into the
groundwater and cause considerable
damage to the environment.

under normal operating conditions. A
drop in the coolant level indicates
leakage.

If the coolant level has fallen

쮿

top up the coolant.

쮿

Have the reason for the loss of coolant
investigated by a qualified specialist
workshop, e.g. a smart center.

Danger of injury!
The cooling system is

pressurised. Allow the engine to cool
down again before unscrewing the cap.
Allow it to cool down for at least
30 minutes. You could otherwise be
scalded by hot coolant when the cap is

Routines 911

Checking fluids

Checking the brake fluid

A constant fluid level is necessary to
ensure that the car's brake system
remains in perfect working order.

Checking the brake fluid level

쮿

Open the front luggage compartment.

쮿

Turn the four retaining screws
anticlockwise to remove.

쮿

Remove the storage tray.

쮿

Look down into the reservoir for a
visual check.
> The fluid level must lie between the

MIN and MAX marks.

>Important!
Have the brake fluid topped up only by a
qualified specialist workshop, e.g. in a
smart center.

쮿

If the level is slightly below the MIN
mark, take your car to a qualified
specialist workshop, e.g. a smart
center.

쮿

If the level is significantly below the
MIN mark, call a breakdown recovery
service, e.g. smartmove Assistance or a
qualified specialist workshop, such as a
smart center.

Accident risk!
If the boiling point of the brake

fluid is too low, vapour bubbles could
form in the brake system when the
brakes are subjected to high loads
(e.g. when driving down mountain
passes). This will impair the
effectiveness of the brakes.
Have the brake fluid changed every two
years!

912 Routines

Tyre inflation pressure

Tyre inflation pressure

Tyres are a particularly important aspect
of the car's operating safety and
roadworthiness. For this reason, you must
check the tyre inflation pressure, tyre
tread and tyre condition on a regular
basis.

Accident risk!
If the inflation pressure of a tyre

falls repeatedly,
investigate the tyre for foreign

objects.

check whether there is a leak at the

rim or valve.

Accident risk!
Insufficient tyre pressure leads

to
excessive tyre heat buildup,
increased tyre wear and an increased

risk of causing an accident due to
tyre pressure loss and changes to
driving stability,

increased fuel consumption.
High tyre pressure leads to
a longer brake distance,
poorer traction from all tyres and
increased, uneven wear.
Tyres that are inflated too high are
moreover more susceptible to damage
and therefore increase the general risk
of accidents.

Accident risk!
Always inflate your car's tyres to

the specified pressures. The
temperature and pressure of the tyres
rise during operation. For this reason,
never reduce the tyre pressure of tyres
while warm. The pressure of the tyres
would then be too low once they had
cooled down. If tyre inflation pressure
is too low, tyres could be damaged,
particularly if the car is carrying a
high load and is travelling at high
speed.
Tyre damage could e.g. result in a tyre
bursting, causing you to lose control
over your car; you or others could be
injured as a result.
You should therefore check the tyre
inflation pressure regularly, but at
least every 14 days.

Routines 913

Tyre inflation pressure

Check the tyre inflation pressure before
the start of your journey. There is a table
showing the tyre inflation pressure on
your car's fuel filler flap.

>Note!
Tyre inflation pressures change by about
0.1 bar per 10 °C change in the air
temperature. Always keep the tyre
inflation pressure at the recommended
level.

914 Routines
