must use more force to steer or brake
the vehicle. Because the usual steering
and brak ing capability is not avai lab le,
the risk of accidents or injur ies increases.
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies part ic­
ularly when children remain in the veh i­
cle. Otherwise the ch ild ren could start
the engine or operate electrical equip­
men t such as power w indows.

seconds.
A WARNING
- Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the power steering is not guaranteed. You
must use more force to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to accidents and serious injuries .
- Please note that the brake booster and
power steering only work when the en­
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle. Because the usual steering and braking capability is not available,
the risk of accidents or injuries increases.
- Always take the vehicle key with you when leaving the vehicle, even for a
short period of time. This applies partic­ ularly when children remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi-

tion. Otherwise, there is the risk that the
vehicle could roll.
- 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 a result of heat buildup or if
the engine compartment is heated by sunlight and the engine is hot.
(D Note
If the engine has been under heavy load
for an extended period of time, heat builds
up in the engine compartment after the
engine is switched off - there is a risk of
damaging the engine. For this reason, let
the engine run for at idle for approximate­
ly two minutes before shutting it off.
