Driving 71
- Never remove the ignition key from the
ignit ion lock while the vehicle is mov ing.
Otherwise the steering lock will engage
and you will not be able to steer the vehi­
cle.
- The brake booster and power steering
only work when the eng ine is running. If
the engine is off, you have to use more
force when stee ring or braking. Because
you cannot steer and bra ke as you usual­
ly would, this could lead to crashes and
serious inju ries .
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time . This applies partic­
ular ly when c hildren remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
(D Note
- Avoid high engine speed, full th rottle,
and heavy engine load as long as the en­
gine has not reached operating tempera­
ture yet. You could damage the engine.
- The engine cannot be started by pushing or towing the vehicle.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.

lead to accidents and serious injuries.
- Never remove the ignition key from the
ignition lock while the vehicle is moving.
Otherwise, the steering lock could sud­
denly engage and you would not be able

park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
switched off.
It can also switch on again
after some time if the coolant tempera­
ture rises as the result of a heat buildup
or if the engine is hot and the engine
compartment is additionally heated by
the sun's rays .
(D Note
-If the engine has been under heavy load
for an extended period of time, heat builds up in the engine compartment af­
ter the engine is switched off -there is a
risk of damaging the @ngin@ . For this
reason, let the engine run for at idle for
approximately two minutes before shut ­
ting it off.
(D Tips
