shift down manually when driving downhill to
use the braking effect of the engine.
Back-up programme
A back-up programme exists in case of faults.
In the event of a fault in the gearbox electron-
ics, it will continue to work in one of the cor-
responding back-up programmes. All seg-
ments of the screen are lit up or switched off.
The fault can be seen as follows:
The gearbox only engages certain gears
●
●
Reverse gear R cannot be engaged
The manual gearbox switches off in the
●
back-up programme
Note
If the gearbox switches to the back-up pro-
gramme, visit an Authorised Service as soon
as possible to solve the problem.
Run-in and economical driving
The first 1,500 km
Over the first 1,500 kilometres the engine
must be run in.
104
Operation
Up to 1000 kilometres
Do not drive at more than 3/4 of the maxi-
–
mum speed corresponding to the engaged
gear, i.e. up to 3/4 of the maximum permit-
ted engine speed.
Do not drive at full speed.
–
Avoid high engine speeds.
–
Do not tow a trailer.
–
From 1000 to 1500 kilometres (600 to 900
miles)
Slowly increase the engine speed until
–
reaching the maximum permitted speed of
the engaged gear, i.e. the maximum per-
mitted engine speed.
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on, when all the moving parts have bed-
ded in. How the vehicle is driven over approx-
imately the first 1,500 kilometres (900
miles), determines the success of the proc-
ess of running in the engine.
Even after running in, the vehicle should not
be unnecessarily driven at high engine
speeds. The maximum permitted engine
speed is marked at the start of the red zone
on the rev counter dial. The gear must be
changed up when the red area is reached in
vehicles with a manual gearbox. Extremely
high engine speeds when accelerating are
automatically limited, however the engine is
not protected against high engine speeds
produced by incorrectly changing to a lower
gear, which could cause the engine to run at
revs above the maximum permitted amount,
and consequently result in damage to the en-
gine.
Additionally, vehicles with a manual gearbox
must also bear the following in mind: do not
drive with the engine speed too low. Change
down to a lower gear when the engine no
longer runs smoothly. Observe the recom-

display.
New tyres
New tyres must be submitted to "running in",
given that initially their grip is not yet at the
maximum level. During the first 500 km (120
miles) drive very carefully.
New brake pads
New brake pads do not yet provide maximum
friction capacity. First they must be "run in".
During the first 200 km (120 miles) drive very
carefully.
CAUTION
All the information for speed and engine
speed refers to an engine that operates at op-
erating temperature. Do not run the engine at
high engine speeds, neither when stopped or
while driving.
