General
driving
information
Closing
the
boot
lid
Safety
note WARNING
When open, the boot lid protrudes above
the vehicle, and in the event of an accident, braking or avoidance manoeuvres, it can enj
danger vehicle occupants and other road
users, or damage the vehicle. There is also the
danger of exhaust fumes entering the interior
of the vehicle. There is a danger of injury or
damage to property. Do not drive with the boot lid open.'

'yDrive through water at no faster than
5 km/h, approximately 3 mph.
Safety
note
NOTE
Driving through excessively deep water
too fast can result in water entering the engine compartment, electrical system or transmisjsion. There is a danger of damage to property.
When driving through water, do not exceed the maximum specified water depth and maximum
fording speed.'

Corrosion
of
the
brake
discCorrosion of the brake discs and contaminaj
tion of the brake pads increase in the following
circumstances:'yLow mileage.'yExtended periods when the vehicle is not
used.'yInfrequent use of the brakes.'yAggressive, acidic or alkaline cleaning
agents.
Should corrosion form on the brake discs, the brakes will tend to respond with a pulsating efj fect that generally cannot be corrected.
Condensation
when
vehicle
is
parkedWhen the automatic air conditioning is in operj
ation, condensation develops which exits unj
derneath the vehicle.
Ground
clearance NOTE
If there is insufficient ground clearance,
the front or rear spoiler can contact the ground, for example at curb edges or when
driving into underground car parks. There is a
danger of damage to property. Make sure that
there is sufficient ground clearance.'

LoadsVehicle
equipment
This chapter describes all standard, national
and special equipment available for the model
series. Therefore equipment which is not inj stalled in your vehicle, for example on account
of the selected optional equipment or the
country specification, may also be described
here. This also applies to safety-relevant funcj
tions and systems. Comply with the relevant
laws and regulations when using the correj
sponding functions and systems.
Safety
notes WARNING
A high gross vehicle weight can cause
the tyres to overheat, causing internal damage
and a sudden loss of tyre inflation pressure.
The driving characteristics can be negatively
influenced, for example reduced directional
stability, longer braking distance and modified
steering characteristics. There is a danger of accidents. Comply with the permitted load inj
dex of the tyre, and do not exceed the permitj
ted gross vehicle weight.'

Lashing
eyes
in
the
boot
Four lashing eyes are located in the boot for
securing the load.
Equipment for securing the transported load, such as lashing straps, tensioning straps or
luggage nets, must be secured to the lashing eyes in the boot.
Floor
net
The floor net can also be used for securing the load.
Hang the floor net on the eyes in the boot floor.
Roof
rack
General Roof racks are available as special equipment.
Safety
note
WARNING
When driving with a roof load, for examj
ple with a roof rack, the higher centre of gravity can mean that driving safety is no longer guarj
anteed in critical driving situations. There is a danger of accident or damage to property. Donot deactivate Dynamic Stability Control DSC
when driving with a roof load.'

'yPlace heavy items of luggage at the botj
tom.'ySecurely fasten the luggage, for example
with tensioning straps.'yDo not allow objects to protrude into the
swing range of the boot lid.'yDrive cautiously and avoid sudden accelerj
ation, braking or cornering.Seite 198Driving

General
The vehicle possesses wide-ranging technoloj
gies for reducing consumption and emission levels.
Fuel consumption depends on various factors.
A number of measures, such as a moderate driving style and regular maintenance, can injfluence fuel consumption and reduce burdenon environment.
Remove
transported
load
that
is
not
required
Extra weight increases fuel consumption.
Remove
add-on
parts
after
use
Remove unneeded roof racks after use.Add-on parts on the vehicle interfere with its aerodynamic performance and increase fuel
consumption.Closing
windows
and
the
Glass
Roof
An opened Glass Roof or opened window inj creases the drag and thus reduces the range.
Tyres
General Tyres can have differing effects on fuel conj
sumption. For example, fuel consumption can be affected by tyre size.
Checking
tyre
inflation
pressure
regularly
Check and, if necessary, correct tyre inflation
pressures at least twice a month and before
setting off on a longer journey.
Insufficient tyre inflation pressure increases
rolling resistance and consequently fuel conj
sumption and tyre wear.
Drive
off
immediately
Do not warm up the engine with the vehicle at a standstill; it is preferable to set off straight
away, driving at moderate engine speeds.
This brings the cold engine to operating temj
perature as quickly as possible.
Drive
with
foresight Anticipating the road situation and adopting asmooth driving style will reduce fuel consumpj
tion.
Avoid accelerating and braking unnecessarily. Keep an appropriate distance from the precedjing vehicle.Seite 199Saving

Avoid
high
engine
speeds
Driving at low engine speeds lowers fuel conj
sumption and wear.
Pay attention to the shift point indicator, see page 110, in the vehicle, if fitted.
Make
use
of
overrun
mode
When approaching a red traffic light, take your foot off the accelerator and allow the vehicle to
roll.
On downward stretches, take your foot off the
accelerator and allow the vehicle to roll.
The fuel supply is interrupted in overrun mode.
Switch
off
the
engine
if
stopping
for
a
relatively
long time
Stopping
the
engine
When you stop the vehicle for longer periods, for example at traffic lights, railway crossingsor in traffic jams, switch off the engine.
Auto
Start
Stop
functionThe Auto Start Stop function of the vehicle
shuts off the engine automatically during a
stop.
If the engine is switched off and then started again, the fuel consumption and emissions arereduced compared with a permanently running
engine. Savings can be made just by stopping
the engine for a few seconds.
Fuel consumption also depends on other facj
tors, such as driving style, road condition, maintenance or environmental factors, for exjample.Switch
of
functions
which
are
not
currently
required
Functions such as seat heating or rear window
heating require a great deal of energy and rej
duce the range, especially in city traffic and
stop-and-go traffic.
Switch these functions off if they are not rej
quired.
Have
the
maintenance
done Have the vehicle serviced regularly to achieve
optimal economy and lifetime. BMW recomj
mends having maintenance work carried out by a BMW Service Partner.
