Driving tips  
Saving fuel  
Vehicle features and options  
Close the windows and glass  
sunroof  
Driving with the glass sunroof and windows  
open results in increased air resistance and  
thereby reduces the range.  
This chapter describes all standard, country-  
specific and optional features offered with the  
series. It also describes features 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 systems. When using these functions and  
systems, the applicable laws and regulations  
must be observed.  
Tires  
General information  
Tires can affect fuel consumption in various  
ways, e.g., tire size may influence fuel con‐  
sumption.  
General information  
The vehicle contains advanced technologies  
for the reduction of fuel consumption and  
emission values.  
Check the tire inflation pressure  
regularly  
Check and, if needed, correct the tire inflation  
pressure at least twice a month and before  
starting on a long trip.  
Fuel consumption depends on a number of dif‐  
ferent factors.  
Carrying out certain measures, such as a mod‐  
erate driving style and regular maintenance,  
can influence fuel consumption and the envi‐  
ronmental impact.  
Low tire inflation pressure increases rolling re‐  
sistance and thus raises fuel consumption and  
tire wear.  
Drive away immediately  
Remove unnecessary cargo  
Do not wait for the engine to warm-up while  
the vehicle remains stationary. Start driving  
right away, but at moderate engine speeds.  
Additional weight increases fuel consumption.  
Remove attached parts  
following use  
This is the quickest way of warming the cold  
engine up to operating temperature.  
Remove roof-mounted luggage racks which  
are no longer required following use.  
Look well ahead when  
driving  
Attached parts on the vehicle impair the aero‐  
dynamics and increase the fuel consumption.  
Driving smoothly and proactively reduces fuel  
consumption.  
Avoid unnecessary acceleration and braking.  
By maintaining a suitable distance to the vehi‐  
cle driving ahead of you.

Driving tips  
Saving fuel  
Avoid high engine speeds  
As a rule: driving at low engine speeds lowers  
fuel consumption and reduces wear.  
Switch off any functions that  
are not currently needed  
Functions such as seat heating and the rear  
window defroster require a lot of energy and  
reduce the range, especially in city and stop-  
and-go traffic.  
Use 1st gear to get the vehicle moving. Start‐  
ing with the 2nd gear, accelerate rapidly. When  
accelerating, shift up before reaching high en‐  
gine speeds.  
Switch off these functions if they are not  
needed.  
When you reach the desired speed, shift into  
the highest applicable gear and drive with low  
engine speed and at a constant speed.  
Have maintenance carried  
out  
If necessary, observe the vehicle's gear shift  
indicator, refer to page 89.  
Have the vehicle maintained regularly to ach‐  
ieve optimal vehicle efficiency and service life.  
BMW recommends that maintenance work be  
performed by a BMW dealer’s service center.  
Use coasting  
When approaching a red light, take your foot  
off the accelerator and let the vehicle coast to  
a halt.  
For information on the BMW Maintenance  
System, refer to page 201.  
For going downhill take your foot off the accel‐  
erator and let the vehicle roll.  
The flow of fuel is interrupted while coasting.  
Switch off the engine during  
longer stops  
Switch off the engine during longer stops, e.g.,  
at traffic lights, railroad crossings or in traffic  
congestion.  
Auto Start/Stop function  
The Auto Start/Stop function of the vehicle au‐  
tomatically switches off the engine during a  
stop.  
If the engine is switched off and then restarted  
rather than leaving the engine running con‐  
stantly, fuel consumption and emissions are  
reduced. Savings can begin within a few sec‐  
onds of switching off the engine.  
In addition, fuel consumption is also deter‐  
mined by other factors, such as driving style,  
road conditions, maintenance or environmental  
factors.
