The essentials
● Find the s up
por
t point on the strut (sunken
area) closest to the wheel to be changed
››› Fig. 75.
● Turn the jack*, located below the strut sup-
port point, t
o raise it until tab 1
› ››
Fig. 76
is
below the housing provided.
● Align the jack* so that tab 1 “grips” onto
the hou s
in

g provided on the strut and the
mobile base 2 is resting on the ground. The
b a
se p

late 2 should fall vertically with re-
s pect
t
o the support point 1 .
● Continue turning the jack* until the wheel
i s
s

lightly lifted off the ground. WARNING
● Mak e s

ure that the jack* remains stable. If
the surface is slippery or soft, the jack* could
slip or sink, respectively, with the resultant
risk of injury.
● Only raise the vehicle with the jack* sup-
plied by
the manufacturer. Other vehicles
could slip, with the consequent risk of injury.
● Only mount the jack* on the support points
designed f
or this purpose on the strut, and
always align the jack correctly. If you do not,
the jack* could slip as it does not have an ad-
equate grip on the vehicle: risk of injury!
● The height of the parked vehicle can
chan
ge as a result of variations in tempera-
ture and loading. CAUTION
The vehicle must not be raised on the cross-
bar . On

ly place the jack* on the points de-
signed for this purpose on the strut. Other-
wise, the vehicle may be damaged. Removing and fitting a wheel
Change the wheel after loosening the wheel
bolts
and r

aising the vehicle with the jack.
Taking off the wheel ● Unscrew the wheel bolts using the box
sp anner and p

lace them on a clean surface.
● Take off the wheel.
Putting on the s
pare wheel
When fitting tyres with a compulsory rotation
direction, observe the instructions in
››› page 68.
● Mount the wheel.
● Screw on the wheel bolts in position and
tighten them loosely
with a box spanner.
● Carefully lower the vehicle using the jack*.
● Tighten the wheel bolts in diagonal pairs
usin
g the wheel brace.
The wheel bolts should be clean and turn
easily. Before fitting the spare wheel, inspect
the wheel condition and hub mounting surfa- ces. These surfaces must be clean before fit-
ting the wheel.
T

yres with compulsory direction of ro-
tation A directional tread pattern can be identified
by
the arr

ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.

● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes

Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Never att ac

h the negative cable to fuel sys-
tem components or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult

 page 22.
The airbag system is not a substitute for the
seat belts. The airbag system offers addition-
al protection for the driver and passenger in
combination with the seat belts.
The airbag system comprises the following
modules (as per vehicle equipment): ● Electronic control unit
● Front airbags for driver and passenger
● Knee airbag for the driver
● Side airbags ●
Head airb
ag
● Airbag control lamp  on the instrument
p

anel ››› page 90
● Key-operated switch for front passenger air-
bag
● Contr

ol lamp to disconnect/connect the
front airb
ag.
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if the control
lamp :
● does not light up when the ignition is
switc
hed on ››› page 90,
● turns off after 4 seconds after the ignition
is sw
itched on,
● turns off and then lights up again after the
ignition is sw
itched on,
● illuminates or flashes while the vehicle is
movin
g.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor side collision
● there is a rear-end collision
● the vehicle turns over. WARNING
● The seat belt

s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 75, Correct position
of the vehicle occupants .
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise there is a
danger that during a collision, the system
may fail to trigger, or not trigger correctly. Airbag activation
The airbags deploy extremely rapidly, within
thou
s
andths

of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role,
86

Airbag system
such as the properties of the object the vehi-
c l
e hits
(hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in seri-
ous head-on collisions:
● Driver airbag.
● Front passenger front airbag
● Knee airbag for the driver.
The fol
lowing airbags are triggered in seri-
ous side-on collisions:
● Front side airbag on the side of the acci-
dent.
● Re

ar side airbag on the side of the acci-
dent.
● Cur

tain (head) airbag on the side of the ac-
cident. In an ac

cident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut.

● In a side-on collision the side airbags will
not work
if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-
el.
● Never drive if the interior door panels have
been remov
ed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels
have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or cov
ered if loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry
any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to
the doors. This would impair the protection
offered by the side airbags.
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must
not be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered. ●
Under no cir c

umstances should protective
covers be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side of the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the se
ams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the side airbag system or re-
mova
l and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.

ling.
● For safety reasons, the curtain airbag must
be disab
led in those vehicles fitted with a
screen dividing the interior of the vehicle.
See your technical service to make this ad-
justment.
● There must be no other persons, animals or
obj
ects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only

Airbag system
●
The side and he a
d airbags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the
front door is damaged, the airbag system
may not work correctly. All work carried out
on the front door must be done in a special-
