CAR MAINTENANCE
239
Do not keep aerosol cans
in the car. There is the risk
they might explode. Aerosol
cans must never be exposed to a
temperature above 50°C. The tem-
perature inside the car might go well
beyond that figure when exposed
to the sun’s rays.
INTERIOR PLASTIC PARTS
For routine cleaning of interior plastic parts
use a soft cloth moistened with water and
neutral soap. Remove grease or persisting
stains using appropriate solvent-free prod-
ucts designed to preserve appearance and
colour of plastic components.
IMPORTANTNever use spirit or petro-
leum to clean the glass of the instrument
panel or other plastic components.
STEERING WHEEL/GEAR LEVER
KNOB WITH GENUINE LEATHER
COVERING
These components shall only be cleaned
with water and neutral soap. Never use spir-
it or alcohol-based products.
Before using special products for cleaning
interiors, read carefully label instructions and
indications to make sure they are free from
spirit and/or alcohol-based substances. If
when cleaning the windscreen with special
glass products, some drops fall on the
leather covering of the steering wheel/gear
lever knob remove them immediately and
then clean with water and neutral soap.
IMPORTANTTake the utmost care
when engaging the steering lock to prevent
scratching the leather covering.
CLEANING LEATHER SEATS
– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid and grease stains with
a dry absorbent cloth without rubbing. Then
wipe with a soft cloth or chamois leather
with water and neutral soap. If the stain per-
sists, use specific products, carefully follow-
ing the instructions for use.
IMPORTANTNever use spirit or alco-
holbased products, even in small percentage.
Fabric upholstery of your
car is purpose-made to
withstand common wear
resulting from normal use of the
car. It is however absolutely nec-
essary to prevent hard and/or pro-
longed scratching/scraping caused
by clothing accessories like metal-
lic buckles, studs, “Velcro” fixings,
etc. that stressing locally the fabric
could break yarns and damage the
upholstery as a consequence.

FRONT WHEEL DRIVE WITH
SELF-LOCKING DIFFERENTIAL
(upon request for versions/
markets where applicable)
Alfa Q2characteristics are such as to
guarantee top performance with whatever
road condition.Alfa Q2features front wheel drive with
front mechanical self-locking differential LSD
(Limited Slip Differential). Torque level be-
tween right and left wheel is modulated ac-
cording to the TORSEN Bfront differen-
tial grip. Mechanical modulation is continu-
ous and gradual thus optimizing drive under
whatever running condition and guarantee-
ing smooth drive, high stability and keeping
top comfort conditions.This type of differential enables to exploit
the tyre-road grip at the best even under
poor grip conditions: the driver is however
charged with observing common safety rules
since road safety is always the driver's re-
sponsibility.
