Before starting the engine, make
sure that all vehicle occupants are
wearing their seat belt correctly
(\2
page 39) and the handbrake
(
\2
page 191) is applied.
Starting the engineWarning
G
Never run the engine in an enclosed
space. The exhaust fumes contain poi-
sonous carbon monoxide. Breathing in
exhaust fumes constitutes a health haz-
ard 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
intended protective function. In certain
circumstances, you could then be seri-
ously or even fatally injured. Make sure,
therefore, that all occupants – in particu-
lar, expectant mothers – wear their seat
belt correctly at all times.

until it has reached operating tem-
perature.iYou can start the engine without pre-

Pulling awayWarning
G
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels may lose their grip and the vehicle
could skid.!
CAUTION
Only drive at high speeds once the
engine 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
feature*, an audible warning sounds
for other road users when reverse
gear is engaged (

iDepending on the vehicle's settings,
the vehicle automatically locks itself
centrally after it has driven off, at the
latest (

page 106). The locking
knobs on the front doors and the
sliding door drop down.
You can open the doors from the in-
side at any time.
You can also switch off the automat-
ic door lock (

Only select reverse gear when the ve-
hicle is stationary, otherwise you
could damage the automatic trans-
mission.
iWait until the gear selection has
completed before pulling away.iAutomatic transmission upshifts are
made at higher engine speeds after a
cold start. This helps the catalytic
converter to reach its operating tem-
perature more quickly.

Do not accelerate to prevent your vehi-
cle from rolling backwards on an uphill
gradient. Instead, you should either use
the handbrake or depress the brake ped-
al. This prevents excessive wear on the
clutch.
Select a lower gear (shift range
3, 2 or
1)
(
\2
page 204) in good time on long and
steep downhill gradients, especially if
towing a trailer. This prevents the brakes
from overheating and wearing too rapidly.
It is best not to stop the vehicle immedi-
ately after the brakes have been subject-
ed to an extreme load; continue driving
for a short time instead. The brakes are
cooled down more quickly in the airflow.The first time the brakes are applied af-
ter a long period of driving in heavy rain
without braking, it is possible that:
\4
there will be a delayed braking
response
\4
you will need to depress the brake
pedal more firmly
You should therefore maintain a greater
distance from the vehicle in front.
BrakingWarning
G
There is no power assistance for the ser-
vice brake when the engine is not running.
You will need to use significantly more
force to brake and could therefore lose
control of the vehicle and cause an acci-
dent.
Never switch off the engine while driving.
Warning
G
Make sure that other road users are not
put at risk by your braking.

Warning

Always switch off the engine and apply
the handbrake before leaving the vehicle.
The vehicle could roll away if it is not
secured.
On uphill or downhill gradients steeper
than 15%:
\4apply the handbrake
\4secure an unloaded vehicle by chock-
ing the front axle (\2page 521)
\4secure a loaded vehicle by, for exam-
ple, chocking the rear axle

!
CAUTION
Whenever you park the vehicle, al-
ways remove the key to prevent the
battery from excessively discharg-
ing.
For vehicles which are out of use for
extended periods and have a battery
isolating switch*, switch off the elec-
trical system (
\2
page 338).
Warning
G
Make sure that the exhaust system does
not come into contact with highly flamma-
ble materials, e.g. dry grass or gasoline.
The flammable material could otherwise
ignite and set vehicle components on fire.
