The combination switch for the turn signal
resets automatically after major steering
wheel movements. This will switch off the
corner-illuminating lamps if they were acti-
vated by switching on the left or right turn
signal.
If the turn signal should stay on after mak-
ing the turn, the turn signal and corner-illu-
minating lamp can be switched off by
returning the combination switch to its
original position.
iIf you have switched on the turn signal for
one side but turn the steering wheel in the
opposite direction, the corner-illuminating front
fog lamp comes on for the side indicated by the
turn signal.
The corner-illuminating front fog lamp remains lit
for a maximum of 3 minutes. Afterward, it goes
out even if the turn signal is still switched on.
iThe corner-illuminating lamps temporarily
come on both sides of the vehicle if you turn the
steering wheel in one direction and then in the
other direction shortly thereafter.
iThe corner-illuminating lamps will come on
automatically depending on the steering angle,
even if you did not switch on either turn signal. If
the corner-illuminating lamps came on automat-
ically, they will also go out automatically depend-
ing on the steering angle.
iWhen you shift the transmission in reverse
gear, the corner-illuminating lamp opposite to
your steering direction comes on.
The turn signal has no influence on the
corner-illuminating lamp on the outside of the
curve.
iThe corner-illuminating lamp may remain lit
for a short time. The corner-illuminating lamp
comes on for no more than 20 seconds with the
vehicle standing still. It is then switched off even
if the turn signal is still switched on or you have
turned the steering wheel to full lock.

Warning!G
Make sure absolutely no objects are ob-
structing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.

speeds as this may shorten its service life.
!In order to avoid damage to the transmis-
sion, place the gearshift lever to reverse gear
only when the vehicle is stopped.

Warning!G
It is dangerous to shift the gear selector le-
ver out of P or N if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
iShifting from gear positionP to positionR,
N, or D is only possible with the brake pedal de-
pressed. Without the brake pedal depressed, the
gear selector lever can be moved, but the park-
ing pawl remains engaged, not allowing shifting
to occur.
iWait for the gear selection process to com-
plete before setting the vehicle in motion.
!Shift the automatic transmission toP orR
only when the vehicle is stopped in order to avoid
damaging the transmission.

higher degree of effort is necessary to brake
and steer the vehicle.
Warning!G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
