_& WARNING
-Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
(D Tips
- The light sensor* for automatic dynamic
headlight range control* is located in the
rear view mirror mount. You should
therefore not apply any stickers to the
windshield in this area in order to pre­
vent malfunctions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display ~
page 22.
- You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting. Clear vision 4

Stowing luggage .
In a collis ion, the laws of phys ics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can ca use
serious in jury . Items in the vehicle pick up ki­
netic energy which varies w ith the vehicle and
the weight of the item . Vehicle speed is the
most signif icant factor.
F or example, in a frontal coll is ion at a speed
of 30 mph (48 km/h), the forces acting on a
10- lb (4 .5 kg) object are about
20 times the
normal weight of the item . This means that
the we ight of the item would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an
item of that
weight flying freely through the passenger compartment can cause in a collis ion at a
speed considered relatively low .
A WARNING
-Weak, damaged or imprope r straps used
to secure items to tie-downs can fail dur­ in g hard braking or in a collision and cause
se rio us personal injury.
- Always use su itable reta ining straps a nd
p roperly secu re items to the tie-downs in
the l uggage compa rtment to he lp pre­
vent i tems from shift ing or fly ing fo r­
ward.
- Never at tach a chi ld seat tether strap to
a t ie -down.
- For s trength-re lated reasons, the mou nt­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg) . Heavi ­
er objects will not be adequately sec ured
- there is a risk of injury.
