_& 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

Emergency flasher
The emergency flasher makes other motorists
aware that you or your vehicle are in an emer­
gency situation .
Fig. 41 Center consol e: eme rge ncy flash er sw itc h
.,. Press the switch&..~ fig. 41 to turn the
emergency flashers on or off.
When the emergency flasher is on, all four
turn signals blink at the same time. The turn
signal indicator lights
B DI in the instru­
ment cluster, as well as the light in the emer­
gency flasher switch &.. blink likewise. The
emergency flasher also works when the igni­
tion is turned off.
The emergency flashers will turn on automati­
cally if you are in an accident where the airbag
has deployed.
@ Tips
You should turn on the emergency flashers
when:
- you a re the last vehicle standing in a traf­
fic jam so that any other vehicles coming
can see you, or when
- your vehicle has broken down or you are
in an emergency situation, or when
- your vehicle is being towed by a tow
truck or if you are towing another vehicle
behind you.

H igh beam assist is only intended to assist
the driver. The driver is still responsible for controlling the headlights and sw itching
th e high beams on and off manually de­
pending on traffic, l ighting and visibility
condi tions. Failure to intervene manually
may lead to ris k of accident . It may be nec­
essary to operate the high beams man ua l­
ly in the following situat ions, e.g .:
- For adverse weather conditions such as
fog, heavy rain, blowing snow or spraying
water .
- On roads where oncoming traffic may be
partia lly obsc ured such as expressways .
-If there are individuals on the road with
no light ing or poor lighting, such as cy ­
cl ists .
- In tight c urves and on steep s lopes .
- In poorly lit areas.
- With strong reflectors su ch as signs.
- If the area of the windshie ld nea r th e
sensor is fogged over, dirty, icy or cov­
ered w ith a st icker.
(D Tips
- The high beam ass ist is active above a
speed of approx . 25 mph (40 km/h).
- If afte r activation, your speed falls below
approx . 15 mp h (24 km/h), the high
beams w ill automatically be switched

the event of sudden braking or a crash.
- Always remove objects from the instru­
ment panel. Any items not stored could
slide around inside the vehicle while driv­
ing or when accelerating or when apply­
ing the brakes or when driving around a
corner.
- When you are driving make sure that
anything you may have placed in the cen­
ter console or other storage locations cannot fall out into the footwells. In case
of sudden braking you would not be able
to brake or accelerate.
- Any articles of clothing that you have
hung up must not interfere with the driv­
er's view. The coat hooks are designed
only for lightweight clothing. Never hang
any clothing with hard, pointed or heavy
objects in the pockets on the coat hooks.
During sudden braking or in an accident -
especially if the airbag is deployed -
these objects could injure any passen­ gers inside the vehicle .
- To reduce the risk of personal injury in an
accident or sudden stop, always keep the
glove compartment closed while driving .
- Read and follow all WARNINGS
¢ page 170, Important safety instruc­
tions on the side airbag system.
- Hang clothes in such a way that they do
not impair the driver's vision.
- The coat hooks must only be used for lightweight clothing . Do not leave any
heavy or sharp edged objects in the pock­
ets which may interfere with the side cur­
tain airbag deployment and can cause
personal injury in a crash.
- Do not use coat hangers for hanging
clothing on the coat hooks as this can in­
terfere with proper deployment of the
side curtain airbags in an accident.
- Do not hang heavy objects on the coat
hooks, as they could cause personal in­
jury in a sudden stop.
(D Note
Objects located on the rear shelf that rub
against the rear window could damage the
heating wires for the rear window defog­
ger.
@ Tips
- A vent slot is located between the shelf
and the rear window. Do not block the
vent with any items you may place on the
rear window shelf.
- Do not place bulky items on the rear win­
dow shelf as they could restrict or block
the driver's vision in the rear view mirror.
Cooler
Introduction
Applies to vehicles: wi th coo ler
Please clean the cooler before using it for the
first time ¢
table on page 216.
You can only switch on the cooler if
- the temperature in the luggage compart­
ment is below 131 °F (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds
131 °F (55 °C). Once the temperature falls
below 131 °F (55 °C) again, the cooler
switches on again automatically.
- the battery is adequately charged. The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the battery from discharg­ ing. The cooler switches back on again auto­
matically when the battery voltage increases
again (e .g. after starting the engine).
The cooler cools to 42.8 °F
(+ 6 °C) and the
freezer cools to 21.2 °F (-6 °C) in optimum
cooling conditions. The cooling performance
is affected by the temperature in the luggage
compartment . The temperature inside the
cooler will be higher if the luggage compart-
ment is hot. .,.
