• Press the key¢ fig. 88 -the engine will
start.
Switching the ignition on/off
If you would like to switch the ignition on
without starting the engine, follow these
steps:
• Insert the key into the ignition lock .
• Press the key briefly
without pressing the
brake pedal.
• To switch the ignition off, press the key
again.
When starting the engine, major electrical
loads are switched off temporarily.
You can only remove the key with the ignition
switched off.
If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure .
A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation.
- 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.
- Always take the key with you whenever
you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated. This can lead to seri­
ous injury.
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es­ caping from the vehicle on their own in
the event of an emergency . Depending
on the time of year, people inside the ve­
hicle can be exposed to very high or very
low temperatures.
(D Note
Avoid high engine rpm, full throttle and heavy engine loads until the engine has
reached operating temperature -other­
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
(D Tips
- If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehicle
¢page 33 .
-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 you leave the vehicle with the ignition
switched on, the ignition will switch off
after a certain period of time. Please
note that electrical equipment such as
exterior lights will switch off as well
when that happens.

Your vehicle is equipped with an electrome­ chanical parking brake. The parking brake is
designed to prevent the veh icle from rolling
u nintentionally and replaces the hand brake.
In add ition to the normal functions of a tradi­
t ional hand brake, the electromechanical
parking brake provides various convenience
and safe ty funct ions .
When starting from rest
-The integral start ing ass ist helps you when
driving by automatically releasing the park­
ing brake
c> page 79, Starting from rest .
- When start ing o n inclines, the starting as­
sist prevents the vehicle from unintentional­
ly rolling back. The braking force of the
pa rking brake is not released until suffic ient
driving force has been bui lt up at the
wheels.
Emergency brake function
An emergency brake ensures that the veh icle
can be slowed down even i f the normal brakes
fail ¢ page 79, Emergency braking.

planing) - risk of accident .
- Turn off the cruise control temporar ily
when ente ring turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake. This is
because the cr uise con trol is overridden
by the d river 's acce lerat ion.
- If a bra ke system malfunction such as
overheat ing occurs when the cru ise con­
tro l system is sw itched on, the braking
function in the system may be switched
off. The othe r cruise control f unctions re­
