at to do first ●
Park the vehicle on a horizontal surface
and in a s afe 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 gearbox: Move the sel
ector lever
to position P. ●
If y
ou are towing a trailer, unhitch it from
your vehicle.
● Have the vehicle tool kit ›››

and the spare wheel* ready
›››  page 278.
● 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. 55

they should be changed if they are damaged,
or c l

aned if they are dirty ››› .
Dam ag
ed w
iper blades should be replaced
immediately. These are available from quali-
fied workshops. WARNING
Worn or dirty wiper blades reduce visibility
and incr e

ase the risk of accident and serious
injury.
● Always replace damaged or worn blades or
bla
des which do not clean the windscreen
correctly. CAUTION
● Damag ed or dir

ty windscreen wipers could
scratch the glass.
● If products containing solvents, rough
spong
es or sharp objects are used to clean
the blades, the graphite layer will be dam-
aged.
● Never use fuel, nail varnish remover, paint
thinner or simil
ar products to clean the win-
dows.
● In icy conditions, always check that the
wiper bl
ades are not frozen to the glass be-
fore using the wipers. In cold weather, it may
help to leave the vehicle parked with the wip-
ers in service position ›››
 page 63. CAUTION
● To pr ev

ent damage to the bonnet and the
wiper arms, only leave them in the service
position.
● Before driving, always lower the wiper
arms. Towing and tow-starting the ve-

 page 60.
Tow-starting means starting the engine of
the vehicle while another pulls it.
Towing means one vehicle pulling another
that is not roadworthy.
If the vehicle comes with the Keyless Access
system, towing is only allowed with the igni-
tion on!
The vehicle battery drains if the vehicle is
towed with the engine switched off and the
ignition connected. Depending on the battery
charge status, the drop in voltage may be so
large, even after just a few minutes, that no
electrical device in the vehicle may work e.g.
the hazard warning lights. In vehicles with the Keyless Access system, the steering
wheel cou

ld lock up. WARNING
If the vehicle has no electrical power, the
brak e light

s, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. WARNING
The risk of accidents is high when tow-start-
ing, f or e

xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.88

Fuses and bulbs
is not running, the gearbox oil pump does
not w
ork
and the gearbox is not adequately
lubricated for higher speeds or longer distan-
ces.
If the vehicle has to be towed with a break-
down truck, it must only be suspended at the
front wheels. Reason: the drive shafts are lo-
cated on the front wheels. If the car is towed
with the rear wheels lifted off the road (I.e.
travelling backwards), the drive shafts also
turn backwards. The planetary gears in the
automatic gearbox then turn at such high
speeds that the gearbox will be severely
damaged in a short time. Note
● If it i

s not possible to tow the vehicle in the
normal way, or if it has to be towed further
than 50 km (30 miles), it must be transported
on a special car transporter or trailer.
● Should the power supply to the selector
lever be int
errupted in position P, the selector
lever will be locked. Before the vehicle can be
recovered/manoeuvred you must manually
release the selector lever ›››

F u
se

s
Introduction In general, a fuse can be assigned to various
electric
al

components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em.
● Take care not to cause short circuits in the
electrica
l system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a c urr

ent circuit without fuses can
cause a fire and serious injury. ●
Never u se a f

use with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or simil
ar. CAUTION
● To pr ev

ent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse,
you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse.
● Several components may run on a single
fuse. 91
