G WARNING
Underinflated tyres pose the following risks:
R the tyres may burst, especially as the load and vehicle speed
increase
R the tyres may wear excessively and/or unevenly, which may
greatly impair tyre traction
R the driving characteristics, as well as steering and braking, may
be greatly impaired
There is a risk of an accident.
X Stop the vehicle without making any sudden steering or braking
manoeuvres. Pay attention to the traffic conditions as you do so.
X Safeguard the vehicle against rolling away (Y page 219).
X Check the tyres and, if necessary, follow the instructions for a

General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is started or during a journey. Wa

Ski/snowboard bag
Important safety notes G
WARNING
The skibag in conjunction with the lashing
straps cannot restrain any objects other than skis.
Vehicle occupants could be struck in the
event of sudden braking or an accident, for
instance, if you:
R transport other heavy or sharp-edged
objects in the skibag
R do not secure the skibag with the lashing
straps
There is a risk of accident and injury.
Store only skis in the skibag. Always secure
the skibag with the lashing straps so that it
cannot move around.
A maximum of four pairs of skis or two snow- boards can be transported in the ski/snow-
board bag.
Securing the ski/snowboard bag in the
luggage compartment X
Fold the middle rear seat backrest forwards
(Y page 393).
X Slide the ski/snowboard bag between the
two outside rear seat backrests. Ensure
that the wheels of the ski/snowboard bag
are in the luggage compartment.
X Open the ski/snowboard bag with zip :
and place the skis or snowboards inside it. X
Close the ski/snowboard bag.
X Pull tensioning strap ;tight by the loose
end until the skis or snowboards are held
firmly inside the ski/snowboard bag. X
Engage tensioning strap =in a diagonal
pattern on hooks ?in lashing eyelets A
as shown. EASY-PACK quickfold rear bench seat
Important safety notes G
WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for- wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt cannot protect as intended and
could result in additional injury.
R Objects or loads in the boot/luggage com-
partment cannot be restrained by the seat
backrest.
This poses an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged before every trip.
! When folding the rear seat backrest for-
wards, ensure that there are no items lying
on the seat cushions. These items could
otherwise be damaged or could themselves damage the rear seats. Stowage areas
