- Because the seats can be electrically ad­
justed with the ignition off, never leave
children unattended in the veh icle. Unsu­
perv ised use of the e lectr ic sea t adj ust­
men ts may cause serious injury.
- To reduce the risk of injury in the case of

hicle with the backrest reclined . Safety
be lts and the airbag system only offer
maximum protection when the backrest

erly positioned on the body . The more
the backrest is reclined, the greater the risk of personal injury from an incorrect
seating position and improperly pos i­
tioned safety belts .

matically after approximately 10 mi­
nutes.
- In vehicles w ith the reclining rear seat,

A WARNING ... -
-The ski sack is intended only for the
transportation of skis and other light ob­
jects. To reduce the risk of ser io us per­
sonal injury, never transport heavy or
pointed objects in the ski sack.
- When braking rapidly or during an acci­
dent, the load could be disp laced and
cause injury to occupants.
- Sharp edges o n the load must be covered
for protection. Always fasten the belt
tightly around the sack and its contents. _...

become a hazard for vehicle occupants in
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. .,.
