WARNING
Do not change down for additional engine
braking on a slippery roa dsurface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident. G
WARNING
The clutch may overheat if you hold the vehi-
cle stationary on uphill gradients by depress-
ing the accelerato rpedal. If the clutch does
overheat, a warning tones ounds and a display
message is shown in the multifunction dis-
play. The frictional connection of the clutch
may then be interrupted. The vehicle may roll
away.A s a result, you could cause an acci-
dent.
You will only be able to continue you journey
once the clutch has cooled down and the dis-
play message in the multifunction display has
disappeared.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
Instead, only ever hold the vehicle stationary
on uphill gradients by
R depressing the brake pedal
or
R activating the HOLD function
or
R engaging the electric parking brake
i Bear in mind that the power transmission
between the engine and the transmission
is interrupted when the engine is switched
off. Therefore, to prevent the vehicle from
rolling away, shift the automatic transmis-
sion to park position Pand apply the elec-
tric parking brake when the engine is
switched off and the vehicle is stationary. DIRECTS

Important safety notes
G
WARNING
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is removed.
Never leave children unsupervised in the vehi-
cle. They might release the electric parking
brake. This could lead to aserious or fatal
accident. G
WARNING
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol, for
example. Do not park the vehicle on dry grass-
land or harvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R on vehicles with manual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmission must be in position Pand
the transmission position display must
show Pin the multifunction display. R
the key must be removed from the ignition
lock.
R on uphill or downhill gradients, turn the
fron twheels towards the kerb. Switching off the engine
Important safety notes G
WARNING
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking then requires significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.
Vehicles with manual transmission X
Shift to either first gear or reverse gear R.
X Turn the key to position 0in the ignition
lock and remove it.

If you leave the vehicle parked up for longer
than four weeks, the battery may be damaged
by exhaustive discharging.
X Have the battery disconnected at a quali-
fied specialist workshop or connec ta
trickle charger. If you leave the vehicle parked up for longer
tha
nsix weeks, the vehicle may suffer dam-
age as a result of lack of use.

General driving tips
Coasting with the engine switched off G
WARNING
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effor tto
steer and brake, and you could therefore lose
control of the vehicle and cause an accident. Short journeys
! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This may lead to fuel
collecting in the engine oil and cause
engine failure. Therefore, if you frequently
drive short distances, you should take a 20
minute trip on a motorway or rural road at
least every 500km. Brakes
