Vehicle features and
options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features and functions that are
not necessarily available in your vehicle, e.g., due
to the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. When using these functions and systems,
the applicable laws and regulations must be ob‐
served.
Reducing fuel consumption
General information
The vehicle contains advanced technologies for
the reduction of consumption and emission val‐
ues.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a moder‐
ate driving style and regular maintenance, can in‐
fluence fuel consumption and the environmental
impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts following
use
Attached parts on the vehicle impair the aerody‐
namics and increase the fuel consumption.
Close the windows
Open windows increase air resistance and there‐
fore lead to greater fuel consumption.
Tires
General information
Tires can affect consumption in various ways, for
instance tire size may influence consumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before start‐
ing on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm-up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the quickest way of warming the cold en‐
gine up to operating temperature.
Look well ahead when driving
Driving smoothly and proactively reduces fuel
consumption.
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle
driving ahead of you.
Avoid high engine speeds
Driving at low engine speeds lowers fuel con‐
sumption and reduces wear.
If necessary, observe the vehicle's gear shift indi‐
cator, refer to page
138 .
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and let the vehicle coast to a halt.
