Please observe the running-in hints on
the p re vious page and the tips for s aving
e ne rgy on the following pa ges .
Good, te chnica lly correct and economical
driving e nsures ma ximum durability and
performance for your vehic le.
O verrun
The fue l supply is autom atically s hut off
during overrun, e.g. when the vehicle is
be ing driven down long gradie nts or whe n
braking. To enable the ove rrun cut-off
to take e ffe ct, do not acc elerate during
overrun and do not declutch. To prevent
dam age to the cata ly tic conve rter, ove rrun
cut-off is temp orarily de activate d whe n the
cataly tic conv erte r tempe rature is high.

F l ow -g en er a t e d n o i se s m a y be a ud i bl e

Wa r m in g u p
Run engine wa rm , do not wa rm up in idle.
Do not a pply full throttle until the
op erating te mperature has b ee n reache d.
Corre ct g ear se le ction
Tra ns mis sion in neutral and without
re vving in the lower gears . S top-a nd -g o
tra ffic a nd driving at a spe ed too hig h for
the s ele cted g ear incre ase s wear and fue l
consumption.
Change dow n!
When decreasing speed, shift down into
the next lowe st ge ar. Do not slip the clutch
with a high-re vving engine. This is
es pecially important when hill climb ing.
Clutch op era tion
Alw ays dep ress the clutch pedal hard to
the floor to prev ent shifting difficultie s and
tra ns mis sion dam age.
Whe n driving, do not us e the ped al as a
foot re st; this will ca us e subs tantial clutch
wear.Cooling fan
The cooling fan is controlle d v ia a
therm os witch and the re fore only runs if
nec essary .
Pedals
Do not place any ob je cts in the foot we ll
which could slip under the ped als and
inhibit the pe dal trav el.
To ensure the pedal travel is uninhibited,
there must be no unre strained mats in the
are a of the p edals .
Bat tery ca re
W hen driving slowly or whe n the v ehicle is
stationary, e.g. in slow urban traffic, stop-
and-go traffic or traffic jams, turn off all
unnecessary electrical load s w here
pos sible (e. g. he ated re ar window).
