(D Tips
-If it is difficult to turn the key to position
(D , turn the steering wheel back and
forth slightly to release the steering
wheel lock .
- After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up
in the hydraulic valve adjusters. This is
normal and not a cause for concern .
- If the battery is disconnected and recon­
nected, you have to hold the ignition key
in position
(D for five seconds for the en­
gine to start .
- After switching the ignition off, you can
only remove the key when the selector
lever is in the "P" (Park) position. After
that the selector lever is locked.

.,,. Turn the steering wheel until you hear the
steering wheel lock.
The locked steering helps prevent vehicle
theft .
_& 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 . -
Never remove the ignition key from the
ignition look while the vehicle is moving .
Otherwise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle .
- 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 af­
ter the engine is switched off -there is a
risk of damaging the engine. For this
reason, let the engine run for at idle for
approximately two minutes before shut­
ting it off.

maintain an optimal battery charge level.
@ Tips
- Energy management cannot overcome
the laws of physics. Note that the charge l evel and length of the battery life are
limited .
- When the start ing ability is endangered,
the (•) indicator light turns on
c!:>page20.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is p laced on the battery when
driving short distances, in traffic , and at co ld
times of the year. A lot of energy is used but litt le is generated. It is also critical when the
engine is not running but electrical equip­ ment is switched on . In this case, energy is
used but none is generated .
In situations like this, energy management
will actively regulated the distribution of en­ ergy.
Long periods without use
I f you do not drive your vehicle for several
days or weeks, e lectrica l equipment is gradu­
ally sca led back or switched off . This reduces
energy use and ensures the vehicle will be
able to start after long periods of time. Some
conven ience functions such as opening with
the remote contro l key may not be ava ilab le.
These convenience functions will be available
again once you switch the ign ition on and
start the engine.
With the engine switched off For example, if you listen to the radio when
the engine is switched off, the batte ry w ill
drain .

Smart Technolog y 195
With the engine running
Although electrical energy is generated while driving, the battery can drain. This can happen
when litt le energy is generated, and much is
used and the charge leve l of the battery is not
optimal.
To restore the ba lance of energy, components
that require large amounts of energy are tem­
porari ly scaled back or switched off. Heating
systems in particular require a great deal of energy. If you notice, for example, that the
seat heating* or rear window defroster is not
working, then it has been temporar ily reduced
or switched off . These systems are availab le
again as soon as the energy balance has been
restored.
In add ition, you may notice that the idle
speed has slight ly increased . That is normal
and no cause for concern. Due to the in­
creased idling speed, the additional required
energy w ill be gene rated and the battery will
be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control
modules
Event Data Recorder
This vehicle is equipped with an Event Data Recorder ( EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an airbag deployment or hitting a road obstacle, data that w ill assist in
understanding how a vehicle's systems per­
formed . Th e EDR is designed to record data
related to vehicle dynam ics and safety sys­
tems for a short pe riod of time, typically
30 seconds or less . The EDR in this vehicle is
designed to record such data as:
- How various systems in your veh icle were
operating;
- Whether or not the driver and passenger
safety belts were buckled/fastened;
