the ignition is switched on and the wheels
begin to turn. There is therefore a risk of
being locked out when the vehicle is being
pushed or tested on a dynamometer. Locking/unlocking the vehicle from
the inside
You can centrally lock or unlock the vehicle
from the inside. This feature may be useful if,
for example, you wish to unlock the
passenger door from the inside or lock the
vehicle before you pull away. G

vehicle. They could open a door from the
inside – even if it is locked – and thereby
endanger themselves and others. X

rior if the engine is running and the tailgate
is open. This could poison you. Therefore,
you should make sure that the tailgate is
always closed when the engine is running.
! The tailgate swings up and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and
behind the tailgate. Controls

Risk of accident
Only adjust the steering wheel when the
vehicle is stationary and do not pull away
until the steering wheel adjustment mech-
anism is locked in position. You might oth-
erwise drive without the steering wheel
adjustment mechanism being locked in
position. As a result you could be distracted
from road and traffic conditions by an unex-
pected movement of the steering wheel
and thereby cause an accident.
However, the steerability of the vehicle is
not affected.
When you adjust the steering wheel, make
sure that:
R the steering wheel can be reached with
your arms slightly bent
R you can move your legs freely
R you can see all the displays in the instru-
ment cluster clearly 1

Rear-view mirror
X Adjust the rear-view mirror by hand so you
have a good overview of the traffic condi-
tions.
Rear-view mirror (manual anti-dazzle) 1
Anti-dazzle switch
X Anti-dazzle mode: flick anti-dazzle switch
1 forwards or back.
Rear-view mirror (automatic anti-daz-
zle*) The rear-view mirror automatically goes into
anti-dazzle mode if the ignition is switched on and incident light from headlamps strikes the
sensor in the rear-view mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged and the interior light-
ing is switched on. G
Risk of accident
If the incident light from headlamps cannot
strike the sensor in the rear-view mirror, for
instance by objects in the vehicle, the mir-
rors' automatic anti-dazzle function will not
operate.
Incident light could then dazzle you. This
may prevent you from observing the traffic
conditions, thereby causing an accident. In
this case, adjust the rear-view mirror man-
ually. Exterior mirrors
G
Risk of accident
The exterior mirrors reduce the size of the
image. Objects are actually closer than
they appear. You could misjudge the dis-
tance from vehicles driving behind and
cause an accident, e.g. when changing
lane. For this reason, make sure of the
actual distance from the vehicle driving
behind by glancing over your shoulder.
The convex exterior mirrors provide a larger
field of vision.
At low outside temperatures, the exterior mir-
rors are heated automatically. Controls

Light switch
For safety reasons, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, daytime operation of headlamps varies
due to legal and voluntary requirements. In
these countries, the constant headlamp
mode is automatically switched on when the
engine is started.
i If you drive in countries in which traffic
drives on the opposite side of the road to
the country where the vehicle is registered,
oncoming traffic may be dazzled by the
asymmetrical dipped-beam headlamps.
Have the headlamps changed to symmet-
rical dipped beam when driving in these
countries. You can obtain information
about this from any Mercedes-Benz Service
Centre. $
