Tires

Vehicle features and

options

General information

Tires can affect consumption in various ways, for

instance tire size may influence consumption.

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.

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.

Reducing fuel consumption

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.

General information

The vehicle contains advanced technologies for

the reduction of consumption and emission val‐

ues.

This is the quickest way of warming the cold en‐

gine up to operating temperature.

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.

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.

Remove unnecessary cargo

Additional weight increases fuel consumption.

Avoid high engine speeds

Driving at low engine speeds lowers fuel con‐

sumption and reduces wear.

Remove attached parts following

use

Attached parts on the vehicle impair the aerody‐

namics and increase the fuel consumption.

If necessary, observe the vehicle's gear shift indi‐

cator, refer to page 138.

Close the windows

Open windows increase air resistance and there‐

fore lead to greater fuel consumption.

Use coasting conditions

When approaching a red light, take your foot off

the accelerator and let the vehicle coast to a halt.

242

Saving fuel

DRIVING TIPS

For going downhill take your foot off the acceler‐

ator and let the vehicle roll.

ECO PRO

The flow of fuel is interrupted while coasting.

Concept

ECO PRO supports a driving style that saves on

consumption. For this purpose, the engine con‐

trol and comfort features, for instance the climate

control output, are adjusted.

Switch off the engine during

longer stops

Switching off the engine

Under certain conditions the engine is automati‐

cally decoupled from the transmission in the D

selector lever position. The vehicle continues

traveling with the engine idling to reduce con‐

sumption. The D selector lever position remains

engaged.

Switch off the engine during longer stops, for in‐

stance at traffic lights, railroad crossings or in

traffic congestion.

Auto Start/Stop function

The Auto Start/Stop function of the vehicle auto‐

matically switches off the engine during a stop.

In addition, context-sensitive information, ECO

PRO tips, can be displayed to assist with a fuel-

efficient driving style.

If the engine is switched off and then restarted

rather than leaving the engine running con‐

stantly, fuel consumption and emissions are re‐

duced. Savings can begin within a few seconds

of switching off the engine.

The achieved extended range is displayed in the

instrument cluster as bonus range.

General information

The system includes the following

EfficientDynamics functions and

EfficientDynamics displays:

In addition, fuel consumption is also determined

by other factors, such as driving style, road con‐

ditions, maintenance or environmental factors.

▷ ECO PRO bonus range, refer to page 244.

Switch off any functions that are

not currently needed

Functions such as seat heating and the rear win‐

dow defroster require a lot of energy and in‐

crease fuel consumption, especially in city and

stop-and-go traffic.

▷ ECO PRO seat climate control, refer to

page 244.

▷ ECO PRO climate control, refer to page 244.

▷ ECO PRO light and sight, refer to page 244.

▷ Coasting driving condition, refer to page 245.

▷ Driving style analysis, refer to page 246.

Switch off these functions if they are not needed.

The ECO PRO driving mode supports the en‐

ergy conserving use of comfort features. These

functions are automatically deactivated partially

or completely.

Overview

Have maintenance carried out

Have the vehicle maintained regularly to achieve

optimal vehicle efficiency and service life. BMW

recommends that maintenance work be per‐

formed by a BMW service center.

For information on the BMW Maintenance Sys‐

tem, refer to page 290.
