2018 Alfa Romeo 4C gearbox

This also acts on the dynamic vehicle control systems
(engine, gearbox/transmission, ESC system).
Driving Modes
The Alfa DNA system lever will always return to the
center position after use.
The selected driving mode is indicated by the corre-
sponding LED switching in the panel and by an indi-
cation on the display.
Dynamic Mode
Activation
Move the Alfa DNA system lever upwards (to the letter
“D”) and hold in this position for half a second, until
the corresponding LED lights up and the Dynamic
mode activation indicator appears on the display.
When Dynamic mode is activated, the turbocharger
pressure and engine oil temperature screen is displayed
automatically. When released, the Alfa DNA system
lever will return to the central position.
NOTE:Dynamic Mode will be inhibited until the
vehicle has accumulated 155 miles (250 km).
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
The ESC and ASR system ensures more enjoyable,
sportier driving while guaranteeing the stability of the
vehicle.
Electronic Q2 system:
The system increases vehicle stability while accelerating
on bends, improving the agility of the vehicle.

STARTING AND OPERATING 139

Engine And Gearbox/Transmission:
The system adjusts the transmission shift calibration for
sportier shifting.
NOTE:In Dynamic mode, the engine response to the
accelerator pedal position increases considerably. Con-
sequently, driving is less fluid and comfortable.
Deactivation
To deactivate Dynamic mode and return to Natural,
move lever downwards (to letter “A”) and hold for half
a second.
The LED corresponding to Natural mode will light up
and the Natural mode activation indication will appear
on the display.
Race Mode
Activation
Starting in Dynamic mode, move the Alfa DNA system
lever upwards (to the letter “D”) and hold in this
position for five seconds, until the Race mode activation
indicator appears on the display. When Race mode is activated, the longitudinal/lateral
accelerometer indicator screen (G-meter information) is
displayed automatically. This considers gravitational
acceleration (G).
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
These systems are deactivated in order to ensure the
fullest sensation of sport, leaving the driver in full
control of the vehicle. When the vehicle is in unstable
conditions, the ESC reactivates automatically when the
brake pedal is pressed until the ABS intervenes, thus
returning the vehicle to stable conditions. To deactivate
the ESC and ASR systems, reactivate Race mode.
Electronic Q2 system:
The system increases vehicle stability while accelerating
on bends, improving the agility of the vehicle.
Engine And Gearbox/Transmission:
The system adjusts the transmission shift calibration for
sportier shifting.
NOTE:
In Race mode, the sensitivity of the accelerator
pedal increases considerably. Consequently, driving is
less fluid and comfortable.
140 STARTING AND OPERATING

In Race mode, the transmission only works in
MANUAL mode.
Deactivation
To deactivate Race mode and return to Dynamic mode,
move the Alfa DNA system lever downwards (to letter
“A”) and keep it in this position for half a second.
The LED corresponding to Dynamic mode will light up
and the Dynamic mode activation indication will ap-
pear on the display.
Natural Mode
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
ESC and ASR system thresholds are aimed at providing
comfort and safety in normal grip and driving condi-
tions.
Electronic Q2 system:
The system is calibrated to ensure the best driving
comfort.
Engine And Gearbox/Transmission:
Standard response shifting.
All Weather Mode
Activation
Move the Alfa DNA system lever downwards (to the
letter “A”) and hold in this position for half a second,
until the corresponding LED lights up and the All
Weather mode activation indicator appears on the dis-
play.
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
ESC and ASR system thresholds are aimed at ensuring
maximum safety in low-grip driving conditions. It is
advisable to select All Weather mode in the presence of
low-grip road surfaces.
Electronic Q2 System:
The system is deactivated.
Engine And Gearbox/Transmission:
Standard response shifting.
Deactivation
To deactivate All Weather mode and return to Natural
mode, move the Alfa DNA system lever upwards (to
letter “D”) and keep it in this position for half a second.

•Check cleanliness of tailgate locks.
• Check cleanliness and lubrication of chassis and
steering linkage.
• Visually inspect condition of: engine, gearbox, trans-
mission, pipes and hoses (exhaust - fuel system -
brakes) and rubber elements (gaiters - sleeves -
bushes - etc.).
• Check battery charge and battery fluid level (electro-
lyte).
• Visually inspect condition of the auxiliary drive belts.
• Check and, if necessary, change engine oil and re-
place oil filter.
• Check and, if necessary, replace air cleaner filter.
Using the vehicle on a track should be regarded as an
exception. The vehicle has been designed and manufac-
tured for road use.
Change engine oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment.
This type of vehicle use is considered Severe Duty. If the vehicle is operated in a dusty or dirty environ-
ment the engine air filter has to be changed every 6,500
miles (10,000 km).
Once A Month Or Before A Long Trip/Periodic
Checks
Every 600 miles (1,000 km) or before long trips, check
and, if necessary, top off the following:
•
Check engine oil level.
• Check brake fluid level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for un-
usual wear or damage.
• Check the fluid levels of the coolant reservoir and
brake master cylinder reservoir, and add as needed
• Check function of all interior and exterior lights.
Every 2,000 miles (3,000 km) check and, if necessary, top
up: engine oil level.

Alfa Twin Clutch Transmission
• Gearbox: Full synthetic 75W-85 manual transmission fluid meeting
MS.90021 or FPW9.55550–MZ3 or the API GL4 specification.
• Control System: Use only Mopar C Series DDCT SAE 75W Hydraulic
Fluid or equivalent.
Failure to use the correct fluid may affect the function or performance of
your transmission.
Brake Master Cylinder We recommend you use Mopar DOT 4 meeting MS.90039. If DOT 4 brake
fluid is not available, then DOT 3 is acceptable.
DOT 4 brake fluid must be changed every two years regardless of mileage.
