e
Wh

at to do first ●
Park the vehicle on a horizontal surface
and in a s af
e p

lace as far away from traffic as
possible.
● Apply the handbrake.
● Switch on the hazard warning lights.
● Manual gearbox: select the 1s
t gear.●
Automatic ge
arbox: Move the selector lever
to position P.
● If you are towing a trailer, unhitch it from
your v
ehicle.
● Have the vehicle tool kit ›››

 page 95
and the spare wheel* ready
›››  page 286.
● Observe the applicable legislation for each
countr
y (reflective vest, warning triangles,
etc.).
● All occupants should leave the vehicle and
wait in a s
afe place (for instance behind the
roadside crash barrier). WARNING
● Alw a

ys observe the above steps and pro-
tect yourself and other road users.
● If you change the wheel on a slope, block
the wheel on the oppo
site side of the car with
a stone or similar to prevent the vehicle from
moving. 64

The essentials
Make sure the battery clamps have sufficient
met al-t
o-met
al contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 270.
● 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
awa
y from batteries, danger of explosion.
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
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the
positive terminals are connected. Changing the wiper blades

Safe driving
● Belt
t
ensioners for the front seats,
● front airbags,
● knee airbags,
● side airbags in the front seat backrests,
● Side airbags in the rear seat backrests*,
● head-protection airbags,
● “ISOFIX” anchor points for child seats in
the rear s
ide seats with the “ISOFIX” system,
● height-adjustable front head restraints,
● rear head restraints with in-use position
and non-use pos
ition,
● adjustable steering column.
The safety
equipment mentioned above
works together to provide you and your pas-
sengers with the best possible protection in
the event of an accident. However, these
safety systems can only be effective if you
and your passengers are sitting in a correct
position and use this equipment properly.
Safety is everyone's business! Correct position of the vehicle
occup

ants
Correct sitting position for the driver Fig. 84

g wheel. Fig. 85
Correct head restraint position for the
driv er
. For your own safety and to reduce the risk of
injur
y
in the ev

ent of an accident, we recom- mend the following adjustments for the driv-
er:
– Adjust the steering wheel so that there is a
dist

ance of at least 25 cm between the
steering wheel and the centre of your chest
››› Fig. 84.
– Move the driver's seat forwards or back-
ward

s so that you are able to press the ac-
celerator, brake and clutch pedals to the
floor with your knees still slightly angled
››› .
– Ensure that you can reach the highest point
of the s
t

eering wheel.
– Adjust the head restraint so that its upper
edge is

at the same level as the top of your
head, or as close as possible to the same
level as the top of your head ››› Fig. 85.
– Move the seat backrest to an upright posi-
tion so that

your back rests completely
against it.
– Fasten your seat belt securely ›››
page 80.
– Keep both feet in the footwell so that you
have the

vehicle under control at all times.

Self-help
●
The to w r
ope must not be twisted. Other-
wise the front tow line anchorage could be
pulled off the vehicle. Indications for tow-starting
Vehicle's should not generally be tow-star-
ted.
The jump s

tart should be used instead
›››  page 70.
For technical reasons, towing the following
vehicles is not allowed:
● Vehicles with an automatic gearbox.
● If the vehicle battery is discharged, be-
cau se in

vehicles with the Keyless Access
locking and ignition system the steering re-
mains locked and the electronic parking
brake cannot be deactivated nor can the elec-
tronic lock of the steering column be re-
leased if they are activated.
● If the battery is flat, it is possible that the
engine contr
ol units may not operate correct-
ly.
However, if the vehicle must absolutely be
tow-started (in the case of manual gearbox-
es):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights. ●
Once both v
ehicles are moving, release the
clutch.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. Note
The vehicle can only be tow-started if the
electr onic

parking brake and, if appropriate,
the electronic lock of the steering column are
deactivated. If the vehicle has no power sup-
ply or there is an electric system fault, the
engine must be tow-started to deactivate the
electronic parking brake and the electronic
lock of the steering column. Anchoring the front tow line
Fig. 98
Right side of the front bumper: tow-
line anc hor
ag

e screwed in. The front towline anchorage is only mounted
if
the
v

ehicle has to be towed. There is a cover with an opening into which
the towline anc

horage is screwed on the right
part of the front bumper.
– To open the cover, press the left side.
– Take the towline anchorage out of the vehi-
cle t

ool kit ››› page 95.
– Screw the towline anchorage into the screw
connection as

far as it will go ››› Fig. 98 and
tighten with the wheel brace.
After use, unscrew the towline anchorage
and fit the cover back on the bumper. Put the
towline anchorage back in the vehicle tool
kit. The towline anchorage should always be
kept in the vehicle.
