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 specifi‐
cation. This also applies to safety-relevant func‐
tions 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 burden on environ‐
ment.
Remove transported load that is
not required
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.
Close windows
Open windows increase drag and consequently
fuel consumption.
Tyres
General
Tyres can have differing effects on consumption.
For example, consumption can be affected by
tyre size.
Checking 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 to operating temper‐
ature as quickly as possible.
Drive with foresight
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 preceding
vehicle.
Avoid high engine speeds
Driving at low engine speeds reduces fuel con‐
sumption and wear.
