Bleep– If you hold the vehicle on a slope for too long without applying the
brakes or handbrake, you will strain
the system (risk of overheating the
clutch).
In this case, an intermittent beep- ing sound will remind you that you
should put your foot on the brake
pedal or apply the handbrake.
– Never leave the vehicle with the engine running when in gear. For
safety reasons you will hear an in-
termittent beeping sound when you
open the door if you have not shifted
into neutral or you have not switched
off the ignition or depressed the
brake pedal.
Special circumstances
On a slippery surface or surface with
little grip, change to manual mode
(A/M) and select second gear before
accelerating to avoid wheelspin.
Operating faults
i
If this warning light comes on
when the vehicle is in motion , it
indicates a fault in the system. In most
cases, you may still drive the vehicle,
although it will not function perfectly.
Contact an approved dealer as soon as
possible.
Towing a vehicle with a sequential
gearbox
If the gearbox is stuck in a gear:
– switch on the ignition;
– select neutral with the brake pedal
depressed;
– check that the gearbox is in neutral (by pushing the vehicle, for exam-
ple).
If you cannot find neutral you must tow
the vehicle with the front wheels raised.
The vehicle should always be towed
with the ignition switched off.

FUSES (1/5)
1
If any electrical component does not
work, check the condition of the fuses.
Remove the fuse using tweezers 1, lo-
cated at the back of flap A.
To remove the fuse from the tweezers,
slide the fuse to the side.
It is not advisable to use the free fuse
locations.
To comply with legislation, or as a
precaution, you can obtain an emer-
gency kit containing a set of spare
bulbs and fuses from an approved
dealer.
Your vehicle is equipped with two fuse
boxes: in the passenger compartment
and in the engine compartment.
A
Fuses in the passenger
compartment
Unclip flap A using notch B to help you.
To identify the fuses, refer to the fuse
allocation label (see the next page for
details), located on the rear of flap A.
B
Check the fuse in question
and replace it, if neces-
sary, by a fuse of the same
rating.
If a fuse is fitted where the rating is
too high, it may cause the electrical
circuit to overheat (risk of fire) in the
event of an item of equipment using
an excessive amount of current.

never be topped up using cold coolant while the engine is very warm.

ed
in the correct proportions. Reminder: only products approved by our Technical
Department may be used for this purpose.
