Corrosion on the brake discs and contaminaj
tion on the brake pads are increased by the folj
lowing circumstances:'yLow mileage.'yExtended periods when the vehicle is not
used at all.'yInfrequent use of the brakes.'yAggressive, acidic, or alkaline cleaning
agents.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their rej sponse - generally this cannot be corrected.
Condensation

features
and
options
This chapter describes all standard, country- specific and optional features offered with theseries. It also describes features that are notnecessarily 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.
Safety
information WARNING
High gross weight can overheat the tires,
damage them internally and cause a sudden
drop in tire inflation pressure. Driving characj
teristics may be negatively impacted, reducing
lane stability, lengthening the braking distanj ces and changing the steering response.
There is a risk of an accident. Pay attention to the permitted load capacity of the tires and
never exceed the permitted gross weight.'

Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the less cargo that can be transported.
Stowing
and
securing
cargo
'yCover sharp edges and corners on the
cargo.'yHeavy cargo: stow as far forward as possij
ble, directly behind and at the bottom of
the rear passenger seat backrests.'yVery heavy cargo: when the rear seat is not occupied, secure each of the outer safetybelts in the opposite buckle.'yIf necessary, fold down the rear backreststo stow cargo.'yDo not stack cargo above the top edge of
the backrests.'ySmaller and lighter cargo: secure with ratchet straps, the floor net, or draw straps.'yLarger and heavy cargo: secure with cargo
straps.Lashing
eyes
in
the
cargo
area
There are four lashing eyes in the cargo area for securing cargo.
Attach load securing aids, such as lashing straps, retaining straps, draw straps or cargonets, to the lashing eyes in the cargo area.
Floor
net To secure the cargo the floor net can also beused.
Hook the floor net into the lashing eyes, refer to page 213.
Roof-mounted
luggage
rack General
information
Roof racks are available as special accessories.
Safety
information WARNING
When driving with roof load, for instance
with roof-mounted luggage rack, driving safety may not be ensured in driving-critical situaj
tions due to the elevated center of gravity. There is a risk of accidents or risk of damage to
property. Do not deactivate Dynamic Stability Control DSC when driving with roof load.'

Securing
Follow the installation instructions of the roof rack.
Roof
drip
rail
with
flaps
The fixing points are located in the roof drip railabove the doors.
Fold the cover outward.
Loading Because roof-mounted luggage racks raise thevehicle's center of gravity when loaded, they
have a major effect on vehicle handling and
steering response.
Therefore, note the following when loading
and driving:
'yDo not exceed the approved roof/axle
loads and the approved gross vehicle
weight.'yBe sure that adequate clearance is mainj
tained for tilting and opening the glass sunroof.'yDistribute the roof load uniformly.'yThe roof load should not extend past the
loading area.'yAlways place the heaviest pieces on the
bottom.'ySecure the roof luggage firmly, for instance
using ratchet straps.'yDo not let objects project into the opening
path of the tailgate.'yDrive cautiously and avoid sudden accelerj
ation and braking maneuvers. Take corners
gently.Seite 214Driving

features
and
optionsThis chapter describes all standard, country-specific and optional features offered with theseries. It also describes features that are notnecessarily 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.
General
information
The vehicle contains advanced technologies
for the reduction of fuel consumption and
emission values.
Fuel consumption depends on a number of difj ferent factors.
Carrying out certain measures, such as a modj erate driving style and regular maintenance, can influence fuel consumption and the envijronmental impact.
Remove
unnecessary
cargoAdditional weight increases fuel consumption.
Remove
attached
parts
following
use
Remove roof-mounted luggage racks which
are no longer required following use.
Attached parts on the vehicle impair the aerojdynamics and increase the fuel consumption.Close
the
windows
and
glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General
information Tires can affect fuel consumption in various
ways, for instance tire size may influence fuel consumption.
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.
Low tire inflation pressure increases rolling rej
sistance and thus raises fuel consumption and
tire wear.
Drive
away
immediately
Do not wait for the engine to warm-up while the vehicle remains stationary. Start drivingright away, but at moderate engine speeds.
This is the quickest way of warming the coldengine 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 vehij cle driving ahead of you.Seite 215Saving

Avoid
high
engine
speeds
Driving at low engine speeds lowers fuel conj
sumption and reduces wear.
If necessary, observe the vehicle's gear shift
indicator, refer to page 113.
Use
coasting When approaching a red light, take your footoff the accelerator and let the vehicle coast toa halt.
For going downhill take your foot off the accelj erator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch

stops
Switching
off
the
engine
Switch off the engine during longer stops, for
instance at traffic lights, railroad crossings or in traffic congestion.
Auto
Start/Stop
functionThe Auto Start/Stop function of the vehicle aujtomatically switches off the engine during a
stop.
If the engine is switched off and then restarted rather than leaving the engine running conjstantly, fuel consumption and emissions are
reduced. Savings can begin within a few secj
onds of switching off the engine.
In addition, fuel consumption is also deterj mined by other factors, such as driving style,
road conditions, maintenance or environmental
factors.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.
Switch off these functions if they are not needed.
The ECO PRO driving program supports the
energy conserving use of comfort features.
These functions are automatically deactivated partially or completely.
Have
maintenance
carried
out
Have the vehicle maintained regularly to achj ieve optimal vehicle efficiency and service life.BMW recommends that maintenance work be
performed by a BMW dealerss service center.
For information on the BMW Maintenance
System, refer to page 261.
ECO
PRO
Concept
ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the enj
gine control and comfort features, for instance
the climate control output, are adjusted.
Under certain conditions the engine is autoj matically decoupled from the transmission in
the D selector lever position. The vehicle conj tinues traveling with the engine idling to rejduce fuel consumption. The D selector lever
position remains engaged.
In addition, context-sensitive instructions are
displayed to assist with an optimized fuel conj
sumption driving style.
The achieved extended range is displayed in
the instrument cluster as bonus range.Seite 216Driving

Coasting
Concept
This function helps to save fuel.
To do this, under certain conditions the engine is automatically decoupled from the transmisj
sion when selector lever position D is set. The
vehicle continues traveling with the engine idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coastj ing.
As soon as you step on the brake or acceleraj
tor pedal, the engine is automatically coupled
again.
General
information Coasting is a component of the ECO PRO drivj
ing mode.
Coasting is automatically activated when ECO PRO mode is called via the Driving Dynamics
Control.
A proactive driving style helps the driver to use the function as often as possible and supports
the fuel-conserving effect of coasting.
