gearbox Alfa Romeo 156 2006 Owner handbook (in English)

GETTING TO KNOW YOUR CAR
160
The failure to follow the
above instructions may
cause serious damage to
the automatic gearbox.
TOWING THE CARWARNINGFor towing the car, abide by
current local regulations. Also follow the in-
structions given in the chapter “In an emer-
gency”.
If the car needs to be towed, observe the
following recommendations:
– if possible, put the car on a rescue ve-
hicle;
– if this is not possible, tow the car by rais-
ing the driving wheels (front) from the
ground;
– if this, too, is not possible, the car may
only be towed for 50 km at a speed below
50 km/h.
The gearshift lever should be at position N
for towing.Cars with automatic gear-
box may be towed only for
short distances and at low
speed: if longer towing is neces-
sary, the driving wheels must be
raised to prevent the gearbox from
being pulled into rotation during
towing.
Do not start the engine
when the vehicle is being
towed.
WARNING

CORRECT USE OF THE CAR
189
PROCEDURE FOR PETROL
ENGINESWARNINGIt is important not to press
the accelerator until the engine has started.
1) Make sure the handbrake is engaged.
2)Move the gear lever to neutral.
3)Fully depress the clutch pedal so that
the starter motor is not forced to crank the
toothed wheels of the gearbox.
4)Ensure that the systems and electrical
devices, especially if they absorb high quan-
tities of energy (e.g. heated rear wind-
screen) are switched off.
5)Turn the ignition to the AV Vposition
and release it as soon as the engine starts.
6)If the engine does not start, return the
key to the STOPposition and repeat the
operation.
WARNINGIf it is difficult to start the en-
gine do not insist with extended attempts
which may damage the catalyzer but con-
tact Alfa Romeo Authorized Services. The ignition switch is fitted with a safety
device which obliges the driver to return the
ignition key to the STOPposition before re-
peating the starting operation if the engine
does not start immediately.
Similarly, when the engine is running, the
device prevents the key being moved from
the MARto the AV Vposition.
STARTING
THE ENGINEWARNINGThe car is fitted with an elec-
tronic engine lock device. If the engine fails
to start see “Alfa Romeo CODE system”.

In addition to the notes
and specifications given be-
low we recommend that,
during the initial period, you do not
drive to full vehicle performance
(for example excessive accelera-
tion, long journeys at top speed,
hard braking, etc.).
To avoid useless con-
sumption of power and
possible draining the bat-
tery, never leave the ignition key
in the MAR position when the en-
gine is not running.
Running the engine in con-
fined areas is extremely
dangerous. The engine consumes
oxygen and produces carbon
monoxide which is a highly toxic
and lethal gas.

tions given on the previous page.
Should it be impossible to set to neutral,
do not tow the vehicle; contact Alfa Romeo
Authorised Services.

HYDRAULIC SYSTEM OIL(fig. 13)
The oil level of the Selespeed system
should be carried out with the car on a lev-
el surface and with the engine stopped and
cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and re-
move the cap (A) checking that the level
corresponds with the MAXmark on the dip-
stick of the actual cap;
– if the level is below the MAXmark, top
up with oil until reaching the correct level;
– after screwing the cap back on, insert
the breather tube completely on the cap
spout and turn the ignition key to STOP.fig. 13

Do not add oil with dif-
ferent characteristics than
those of the oil already in
the system.
The oil level should never exceed the
MAXmark on the dipstick on the COLD
side, if the level is checked cold and on the
HOTside if the level is checked with the
gearbox/differential unit hot.

The level should be between the MINand
MAXmarks of the sector identified by the
word COLD(+40°C).
WARNINGAfter long journeys with the
gearbox/differential unit very hot, the oil
level should be between the MINand
