\1Before each journey, check the vehicle
lighting and the general condition of
the vehicle.
\1Observe the general driving tips at the
end of this section (\2page 116).
You will find information on:
\4regular checks (\2page 181)
\4driving in winter (\2page 235)
\4driving when towing a trailer
(\2page 175)
\4and other driving tips

structed. The vehicle’s operating and road
safety are otherwise jeopardized.
Objects could fall and get caught between
the pedals if you accelerate or brake sud-
denly. You will no longer be able to brake or
accelerate. You could cause an accident,
which could result in injury to yourself and
others.
\4If floor mats and carpets are used, make
sure that these are secured correctly
and cannot slip and that there is suffi-
cient pedal clearance.
\4Do not place any objects in the driver’s
footwell.
\4Store and secure all loose objects so
they cannot get into the driver’s footwell
while the vehicle is in motion.
Warning
G
The doors could open of their own accord
while the vehicle is in motion if they are not
fully closed. For this reason, please make
sure that all the doors are properly closed
and locked before driving off (\2page 52).
Starting the engineWarning
G
Never run the engine in an enclosed space.
The exhaust fumes contain poisonous car-
bon monoxide. Breathing in exhaust fumes
constitutes a health hazard and can lead to
loss of consciousness and death.Warning
G
A seat belt that is worn incorrectly or not at
all, or that is not correctly engaged in the
seat belt buckle, cannot perform its intend-
ed protective function. In certain circum-
stances, you could then be seriously or even
fatally injured. Make sure, therefore, that all
occupants – in particular, expectant moth-
ers – wear their seat belt correctly at all
times.

Pulling awayWarning
G
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
may lose their grip and the vehicle could
skid.!
CAUTION
Only drive at high speeds once the en-
gine has warmed up. This protects the
engine.
When driving on slippery surfaces,
avoid spinning the drive wheels where
possible as this could damage the drive
train.
iOn vehicles with a reverse warning fea-
ture*, an audible warning sounds for
other road users when reverse gear is
engaged (\2page 153).
iDepending on the vehicle's settings,
the vehicle automatically locks itself
centrally after it has driven off, at the
latest (\2page 64). The locking knobs
on the front doors and the sliding door
drop down.
You can open the doors from the inside
at any time.
You can also switch off the automatic
door lock (\2page 64). !
CAUTION
Only select reverse gear when the vehi-
cle is stationary, otherwise you could
damage the automatic transmission.
iWait until the gear selection has com-
pleted before pulling away.iAutomatic transmission upshifts are
made at higher engine speeds after a
cold start. This helps the catalytic con-
verter to reach its operating tempera-
ture more quickly.
