R
ESP ®
still provides support when you
brake.
R and are driving at above 37 mph
(60 km/h), ESP ®
still
intervenes when one
wheel reaches its grip limit even though it
is switched off.
i If ESP ®
is deactivated and one or more
wheels start to spin, the 00E5 warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the
vehicle.
i If ESP ®
is deactivated, it is automatically
reactivated when you drive faster than
37 mph (60 km/h) or if a predefined lateral
acceleration threshold has been exceeded.
Trailer stabilization G
WARNING
If road and weather conditions are poor,
trailer stabilization will not
be able to prevent
the vehicle/trailer combination from
swerving. Trailers with a high center of gravity
can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt your driving style to the
prevailing road and weather conditions.
Trailer stabilization does not work if ESP ®
is
deactivated because of a malfunction.
If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active above speeds of
about 37 mph (60 km/h). EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section ( Y page 60). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of
skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps ( Y page 250) as well as
display messages ( Y page 228).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased
braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function
(Y page 192) and hill start assist
(Y page 141). Theft deterrent locking system
Immobilizer
X To activate: remove the SmartKey from
the ignition lock.
X To deactivate: switch on the ignition.
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.
i The immobilizer is always deactivated
when you start the engine. 64

Bulbs and lamps are an important aspect of
vehicle safety. You
must
therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs G
WARNING
Bulbs and lamps can become very hot. For
this reason, allow them to cool down before
changing them. Otherwise, you could burn
yourself when you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could, for example, damage
the bulbs and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
Halogen bulbs are pressurized and could
explode when you change them, especially if
they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed ( Y
page 109). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. Before changing bulbs Have the following bulbs changed at a

The following contains notes and
recommendations on optimum use of
automatic climate control.
R Activate climate control using
the 0058 and
0056 buttons. The indicator lamps in the
0058 and 0056 buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "defrosting" function briefly
until the windshield is clear again. R
Only use "air-recirculation" mode briefly,
e.g. if there are unpleasant outside odors
or when in a tunnel. The windows could
otherwise fog up, since
no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well. The
indicator lamp in the 00D6 button goes out.120
