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. _...

76 Seats and storage
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. .,.

A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiat ion.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running. If
the engine is off, you have to use more
force when steering or braking . Because
you cannot steer and brake as you usual­ ly would, this could lead to crashes and
serious injuries.
(D Note
- Avo id h igh engine rpm, full throttle and
heavy engine loads until the eng ine has
reached operating temperature -other­
w ise you risk engine damage .
- T he engine cannot be started by pushing
or towing the vehicle.
(0 Tips
- After a co ld eng ine is started, there may
be a brief period of inc reased no ise be­
cause oil pressure must first build up i n
the hydraulic valve adjusters. This is nor­
ma l and not a cause for conce rn.
- If you leave the veh icle with the ignition
switched on , the ign ition w ill switch off
after a certain period of time . Please

Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
11-Keep the switch© pulled and depress the
accelerator. The parking brake stays applied
and prevents the vehicle from rolling back­
ward .
11-You can release the switch<®> once you are
su re that you a re develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
D epending on the weight of the r ig (vehicle
and tra ile r) and the severi ty of the incl ine, you
may roll backwards as you start. Yo u can pre­
vent rolling backwards by holding the parking brake switch<®) p ulled out and acce lerating -
just as you would when starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys­
tem fails or locks.
11-In an emergency, pull the switch(®) and
contin ue to p ull it to slow your vehicle down
with the parking brake.
11-As soon as you release the switch (®) or ac-
ce lerate, the braking process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking function is initiated. The vehicle is
braked at all four wheels by activating the hy­
draulic brake system. Th e brake performance

In order not to activate the emergency brak­
ing by m istake, an audible warning tone (buz­
ze r) sou nds when the switch C®> is pulled. As
soon as the switch(®) is released, or the accel­
e rator pedal is dep ressed, emergency b ra ki ng
stops.
_& WARNING
Emergency braking should only be used i n
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed .
On the ro ad 87
Using the parking b rake to pe rform emer­
gency brak ing will slow your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even with ESC and i ts associated compo­
nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake appl ication can ca use the vehi­
cle to sk id or the re ar end to break away -
risking an acciden t.

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exceeding the maximum speed that you
have set . You will hear a warn ing tone when
your speed exceeds the stored value by ap­ proximately 3 mph (3 km/h). An indicator
light. (USA models) . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns off when the speed decreases below the
stored maximum speed.
Sett ing a threshold is recommended if you
wo uld like to be reminded when you reach a
certain maximum speed . Situations where you
may want to do so include driving in a country
with a general speed limit or if there is a
specif ied maximum speed for winter tires.
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed lim it.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
.. Se lect : ICAR lfunction button> Car systems
control button > Driver assist > Speed warn­
ing.
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of S mph
(10 km/h).
