inoperative .
High qua lity fuels other tha n those liste d on

pos sible in the e ve nt of misfiring,
irregular engine running following a cold
s tart, a s ignificant los s of engine power
or other unusual m alfunctions w hich
may indicate a fault in the ignition
system. If necessary, driving ma y be

Irregular engine running and lack of
powe r when the Ele ctronic S tability
Program (E SP) kicks in are for
ope ra tional re as ons and ca n be
ignored – s ee page 1 19 .zIf unburned fuel enters the catalytic
conv erter, this may res ult in ove rhe ating
and irre parable damage to the c atalytic
conv erter.
You should therefore avoid
unnecessarily long use of the starter
when starting-off, running the tank d ry
(an irre gular fuel s upply w ill lead to
overhea ting) and starting the e ngine by
pushing or towing.

To ensure the full pe dal trave l can be

Towing
Tow ing the vehicl e
Screw the front towing ey e (stowed in a
bag in the lugga ge compartme nt) fully into
the front towing point.
Attac h a tow rope 3 - or b etter still, a tow
ro d 3 - to the towing ey e, neve r to the
bumper or front suspension units.
Plac e the gear s hift le ve r in ne utra l. Switch
on the ignition to re lease the stee ring
colum n lock and to p ermit operation of the
brake lamps , horn and winds cree n wipers . Drive off slowly and avoid jerky
mov eme nts . Impe rm iss ible trac tiv e force s
could da mage the ve hicles .
To prevent the entry of exha ust gases from
the tow ing vehicle , switch on the air re -
circulation sy stem and close the windows.
S ee k the a ss istance of a works hop.
Towi ng serv ice
E ntrust your ve hicle only to the towing
service of your choice and obtain an
e stimate on towing costs be fore e mploying
any tow ing se rvice. In this way y ou avoid
unnecessary c osts and possible insurance
proble ms during claim proce ss ing.

Tyre rep air k it
Minor damag e to the tyre tread, e.g . from
foreign bodie s, can be tem porarily
rep aire d using the ty re re pair kit.
Do not rem ov e foreign bodies from the
tyre s. Damage d are as bigger than 4 m m
and da mage at the ty re rim cannot be
rep aire d using the ty re re pair kit.
The tyre re pair k it can be use d to seal small
puncture s with a liquid seala nt. Use of the
sealant doe s not c onstitute a pe rmane nt
rep air but is des igned as an eme rgency
measure, to allow the vehicle to be driven
while awaiting tyre replace me nt.
The ty re re pair kit ca n also be used to
infla te the tyres to the c orre ct ty re pressure
(se e page 18 0 ) without us ing the s ea lant.For important information – s ee page 1 40 .
If you have a flat ty re:
zPark on a leve l, firm a nd non-s lippery
surface.
zSw itch on haz ard warning lamps , a pply
hand brak e, engage rev ers e ge ar and
switch off engine.
zC orre ctly s et up the warning triangle3.

Nev er use the liquid sealant on more than
one tyre at a tim e.
The tyre repa ir kit is loc ated in a stowag e

Remove the strap from the ty re repair kit by
pressing the tabs on either side of the
