2021 Alfa Romeo 4C ESP

The device still remains active, without
the need to press the CANCEL/RESUME
button to return to the previous condition
once acceleration is concluded.
78) 79)
Automatic deactivation
The device is automatically switched off
in the following cases:
❒ if the ABS or ESC systems intervene;
❒ with vehicle speed under the
established limit; in case of fault to the
system.
STARTING AND DRIVING
76
RESTORING THE STORED SPEED
If the device has been deactivated, for
example by pressing the brake pedal, the
stored speed can be restored as follows:
❒ accelerate gradually until a speed
approaching the one stored is reached;
❒ engage the gear selected at the time
of speed memorising;
❒ press the CANCEL/RESUME button
(2 fig. 48).
INCREASING THE STORED SPEED
This can be done in two ways:
❒ by pressing the accelerator and then
storing the new speed reached;
or
❒ by moving the stalk upwards (+) until
the new speed, which will be stored
automatically, is reached.
Each operation of the stalk will
correspond to a slight increase in speed
(about 1 km/h), while keeping the stalk
upwards will correspond to a continuous
speed increase.
REDUCING THE STORED SPEED
This can be done in two ways:
❒ by deactivating the device and then
storing the new speed
or
❒ by moving the stalk downwards (–)
until the new speed, which will be stored
automatically, is reached.
Each movement of the stalk will
correspond to a slight reduction in speed
of about 1 km/h, while keeping the stalk
held downwards will decrease the speed
continuously.
DEACTIVATING THE DEVICE
The device can be switched off in the
following ways:
❒ by turning the ring nut 1 fig. 48 to
;
❒ by turning the engine off;
❒ by pressing the CANCEL/RESUME
button;
❒ by pressing the brake pedal or the
accelerator; in this last case the system is
not completely deactivated but gives
priority to the acceleration request.
79)When driving with device active, do
not press the “N” button on the
transmission control panel.
80)If operation of the device is faulty or
in the case of failure, turn ring nut
1 fig. 48 to
and contact a dedicated
Alfa Romeo Dealership.

IMPORTANT NOTES
81)
8)
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
Under certain circumstances, objects
close to the vehicle are not detected by
the system and could therefore cause
damage to the car or be damaged
themselves.
The following conditions may influence
the performance of the parking sensors:
❒ the presence of ice, snow, mud or
think paint on the sensor surface may
cause reduced sensitivity of the sensor
itself and therefore reduce the system
performance;
❒ the sensor may detect a non-existent
obstacle (“echo interference”) due to
mechanical interference, for example
when washing the vehicle, in rain (strong
wind), hail;
❒ the signals sent by the sensor can also
be altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems
of trucks or pneumatic drills) near the
vehicle;
❒ the variation in sensor position,
caused by variation in ride (due to
suspension component wear), changing
tyres, overloaded car, or tuning that
lowers the car, for example, may affect
parking sensor system performance.
81)The responsibility for parking and
other dangerous manoeuvres always and
in every case lies with the driver.
While carrying out these manoeuvres,
always make sure that no people
(especially children) or animals are in the
area concerned. The parking sensors are
used to assist the driver, who must never
allow his attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
IMPORTANT
8)The sensor must be clean of mud, dirt,
snow or ice in order for the system to
operate correctly. Be careful not to
scratch or damage the sensors while
cleaning them. Avoid using dry, rough or
hard cloths. The sensors must be washed
using clean water, with the addition of
vehicle shampoo if necessary. When using
special washing equipment such as high
pressure jets or steam cleaning, clean the
sensors very quickly keeping the jet more
than 10 cm away. Also, do not apply
stickers to the sensors.

GENERAL INSTRUCTIONS
❒ Check that the corresponding
contacts are not oxidised and that the
corresponding fuse is intact before
changing the bulb. For the location of
fuses, refer to the paragraph “If a fuse
blows” in this chapter.
❒ replace blown bulbs with others of the
same type and power;
❒ after replacing a headlight bulb,
always check its alignment.
IMPORTANT When the weather is cold or
damp or after heavy rain or after
washing, the surface of headlights or rear
lights may steam up and/or form drops of
condensation on the inside. This is a
natural phenomenon due to the
difference in temperature and humidity
between the inside and the outside of the
glass which does not indicate a fault and
does not compromise the normal
operation of lighting devices. The mist
disappears quickly turning the lights on,
starting from the centre of the diffuser,
extending progressively towards the
edges.
85)The use of hazard warning lights is
governed by the Highway Code of the
country you are driving in: comply with
legal requirements.
IMPORTANT
86)Modifications or repairs to the
electric system that are not carried out
properly or do not take the system
technical specifications into account can
cause malfunctions leading to the risk of
fire.
87) Halogen bulbs contain pressurised
gas, in the case of breakage they may
burst causing glass fragments to be
projected outwards.
88) Due to the high supply voltage, gas
discharge bulbs (Bi-Xenon) should only be
replaced by specialised personnel: danger
of death! Contact a dedicated Alfa Romeo
Dealership.
IMPORTANT
9)Halogen bulbs must be handled by
holding the metallic part only. Touching
the transparent part of the bulb with your
fingers may reduce the intensity of the
emitted light and even reduce the lifespan
of the bulb. In the event of accidental
contact, wipe the bulb with a cloth
moistened with alcohol and let the
bulb dry.

JUMP STARTING
STARTING THE ENGINE
Contact the dedicated Alfa Romeo
Dealership immediately if the
Ywarning light stays on constantly on the
instrument panel .
JUMP STARTING
If the battery is flat, start the engine
using an auxiliary battery with the same
capacity or a little higher than the flat
one.
111) 13)
Proceed as follows to start the vehicle:
❒ connect the positive terminals (+ sign
near the terminal) of the two batteries
with a jump lead fig. 85;
85A0L0116
106)As required by current regulations,
the information on chemical substances
for the protection of human health and
the environment and on the safe use of
the sealing fluid are on the packaging
label. Compliance with the indications on
the label is an essential condition to
ensure the safety and the effectiveness
of the product. Remember to carefully
read the label before use; the user of the
product is responsible for any damages
caused by improper use. The sealing fluid
has an expiry date. Replace the bottle if
the sealant has expired.
107)Wear the protective gloves
provided with the kit.
108)Apply the adhesive label where it
can be easily seen by the driver as a
reminder that the tyre has been treated
with the quick repair kit. Drive carefully,
especially on corners. Do not exceed
80 km/h. Avoid sudden acceleration or
braking.
109)If the pressure has fallen below 1.8
bar, do not drive any further: the Fix&Go
Automatic quick tyre repair kit cannot
guarantee proper hold because the tyre is
too damaged. Contact a dedicated Alfa
Romeo Dealership.
110)Always indicate that the tyre was
repaired using the quick tyre repair kit.
Give the leaflet to the personnel charged
with handling the tyre treated with the
tyre repair kit.
12)Punctures caused by foreign bodies
can be repaired if the damage does not
exceed 4 mm on the tread and on the
shoulder of the tyre. Do not use the repair
kit if the tyre was damaged as a result of
being used when underinflated.
WARNING
3)Dispose of the bottle and the sealant
properly. Have them disposed of in
compliance with national and local
regulations.
