Vehicle equipment
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment and functions which are not installed in
your vehicle, for example on account of the op‐
tional equipment selected or the country variant.
This also applies to safety-relevant functions and
systems. Please comply with the relevant laws
and regulations when using the corresponding
functions and systems.
Reducing fuel consumption
General
The vehicle possesses wide-ranging technolo‐
gies for reducing consumption and emission lev‐
els.
Fuel consumption depends on various factors.
A number of measures, such as a moderate driv‐
ing style and regular maintenance, can influence
fuel consumption and reduce the burden on the
environment.
Remove unnecessary loads
Extra weight increases fuel consumption.
Remove add-on parts after use
If no longer required, remove auxiliary mirrors,
roof racks and rear-mounted racks after use.
Add-on parts on the vehicle interfere with its aer‐
odynamic performance and increase fuel con‐
sumption.
Closing windows and the Glass
Roof
An open Glass Roof or open window increase
drag and consequently fuel consumption.
Tyres
General
Tyres can have differing effects on consumption.
For example consumption can be affected by
tyre size.
Check tyre inflation pressure
regularly
Check and, if necessary, correct the tyre inflation
pressures at least twice a month and before set‐
ting off on a longer journey.
Insufficient tyre inflation pressure increases roll‐
ing resistance and consequently fuel consump‐
tion and tyre wear.
Drive off immediately
Do not warm up the engine with the vehicle at a
standstill; it is preferable to set off straight away,
driving at moderate engine speeds.
This brings the cold engine up to operating tem‐
perature as quickly as possible.
Think ahead
Anticipating the road situation and adopting a
smooth driving style will reduce fuel consump‐
tion.
Avoid accelerating and braking unnecessarily.
Keep an appropriate distance from the vehicle
ahead.
Avoid high engine speeds
Driving at low engine speeds reduces fuel con‐
sumption and wear.
