This
chapter
describes
all
standard,
country-spejcific
and
optional
equipment
available
for
the
model
series.
It
may
therefore
describe
equipj
ment
and
functions
which
are
not
installed
in your
vehicle,
for
example
on
account
of
the
spejcial

or
the

This
also
applies
to
safety-relevant

and

Please
comply
with
the
relevant
laws
and
regulations
when
using
the
corresponding
functions
and
systems.
Reducing
fuel
consumption
General
The
vehicle
possesses
wide-ranging
technoloj
gies
for
reducing
consumption
and
emission
levj
els.
Fuel
consumption
depends
on
various
factors.
A
number
of
measures,
such
as
a
moderate
drivj ing
style
and
regular
maintenance,
can
influencefuel
consumption
and
reduce
the
burden
on
the
environment.
Remove
unnecessary
loadsExtra
weight
increases
fuel
consumption.
Remove
mounted
parts
after
use If
no
longer
required,
remove
auxiliary
mirrors,
roof
racks
and
rear-mounted
racks
after
use.
Add-on
accessories
on
the
vehicle
can
adversely affect
its
aerodynamic
performance
and
increasefuel
consumption.
Close
windows
and
the
glass
sunroof
An
open
glass
sunroof
or
open
window
increase
drag
and
consequently
fuel
consumption.
Tyres GeneralTyres
can
have
differing
effects
on
consumption
figures.
Consumption
can
be
affected
by
the
size of
the
tyres,
for
example.
Check
tyre
inflation
pressure
regularly
Check
and,
if
necessary,
correct
the
tyre
inflationpressures
at
least
twice
a
month
and
before
setj
ting
off
on
a
longer
journey.
Insufficient
tyre
inflation
pressure
enlarges
the
rolling
resistance
and
thus
increases
fuel
conj sumption
and
tyre
wear.
For
further
information:
Tyre
inflation
pressure
information,
see
page
310.
Drive
off
immediately Do
not
warm
up
the
engine
with
the
vehicle
at
a
standstill,
but
instead
set
off
straight
away,
drivj
ing
at
moderate
engine
speeds.
This
brings
the
cold
engine
up
to
operating
temj perature
as
quickly
as
possible.
Think
ahead Anticipating
the
road
situation
and
adopting
asmooth
driving
style
will
reduce
fuel
consumpj tion.
Avoid
accelerating
and
braking
unnecessarily. Keep
an
appropriate
distance
from

Avoid
high
engine
speeds
Driving
at
low
engine
speeds
reduces
fuel
conj sumption
and
wear.
Pay
attention
to
the
optimum
shift

in the
vehicle,
if
fitted.
Make

of

On

stretches,
take
your
foot
off
the accelerator
and
allow
the
vehicle
to
roll.
The
fuel
supply
is
interrupted
in

mode.
Switch
off
the
engine
if
stopping
for
longer
periods
Stopping
the
engine When
you
stop
the
vehicle
for
longer
periods,
for
example
at
traffic
lights,
railway
crossings
or
in
traffic
jams,
switch
off
the

Savings
can
be
made
just
by
stopping

for
a
few
seconds.
Fuel
consumption
also
depends
on
other
factors,
such
as
driving
style,
road
condition,
maintej
nance
or
environmental
factors,
for
example.
