DRIVING TIPS

Saving fuel

Vehicle features and options
This chapter describes all standard, country-
specific, and optional equipment offered with
the series. It also describes features and func-
tions that are not necessarily available in the
vehicle, e.g., due to the selected options or
country versions. This also applies to safety
functions and systems. When using these
functions and systems, the applicable laws
and regulations must be observed.
Reducing fuel consumption
General information
The vehicle contains advanced technologies
for the reduction of consumption and emission
values.
The fuel consumption depends on various fac-
tors such as driving style, road conditions,
maintenance or environmental factors.
Carrying out certain measures such as a mod-
erate driving style and regular maintenance
can influence fuel consumption and the envi-
ronmental pollution.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing attached parts following
use
Attached parts on the vehicle impair the aero-
dynamics and increase the fuel consumption.
Closing the windows
Open windows increase drag and therefore
lead to greater fuel consumption.

Tires
General information
Tires can affect consumption in various ways,
for instance tire size may influence consump-
tion.
Checking the tire pressure regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire pressure increases rolling resistance
and thus fuel consumption and tire wear.
Observe the correct tire inflation pressure as
well as the ECO tire inflation pressure, where
applicable.
Additional information:
Tire pressure specifications, refer to page 268.
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 RPM.
This is the fastest way of warming the cold
engine up to operating temperature.
Anticipatory driving
A smooth and anticipatory driving style re-
duces fuel consumption.
Avoid unnecessary acceleration and braking.
Maintain a suitable distance to the vehicle driv-
ing ahead of you.
Avoid high RPM
Driving at low engine speeds lowers fuel con-
sumption and reduces wear.
If necessary, observe the vehicle's gear shift
indicator.
