CORRECT RIM READING
Below, please find the instructions needed
to understand the meaning of the code
stamped on the rim, as shown in (fig. 5).
Example:
6,5 J x 15 H2 ET 43
6,5=rim width in inches (1)
J=rim drop centre outline (side pro-
jection where the tyre bead
rests) (2)
15=rim nominal diameter in inches
(corresponds to diameter of the
tyre to be mounted) (3=Ø)
H2=“hump” shape and number (relief
on the circumference holding the
Tubeless tyre bead on the rim).
ET 43=camber angle (distance between
disk/rim line and wheel rim cen-
tre line)

FLUIDS AND LUBRICANTS
RECOMMENDED PRODUCTS AND THEIR SPECIFICATIONS
Should non-genuine products be used, lubricants with minimum ACEA A3 properties for petrol engines and ACEA B4 for Diesel engines are tolerated; in this
event top engine performance is not guaranteed.
Using low-quality products, not compliant with ACEA A3 and ACEA B4 properties and specifications could cause engine damages not covered by warranty.
For very cold temperatures, consult Alfa Romeo Authorised Services for the proper Seleniaproduct to use.

FUEL CONSUMPTION
The fuel consumption figures given in the
table below are determined on the basis of
the homologation tests set down by specif-
ic European directives.
The procedures below are followed for
measuring consumption:
–urban cycle: cold starting followed by
driving that simulates urban use of the car;–extra-urban cycle: frequent accel-
erating in all gears, simulating extraurban
use of the car; the speed varies between 0
and 120 km/h;
–combined consumption: is calcu-
lated weighing about 37% of urban cycle
consumption and about 63% of extraurban
consumption.

driving style, general conditions of
the vehicle, trim level/equip-
ment/accessories, load, presence of
a roof rack, use of the climate con-
trol system, other situations that af-
fect air drag may lead to different fu-
el consumption levels than those
measured (see “Reducing running
costs and environment pollution” in
