Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and the vehicle in front of
you. A defensive and smooth driving style
keeps fuel consumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accelerate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con-
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Coasting
When approaching a red light, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
O n a d o w n h il l s lo p e , t a k e y o u r f o o t o f f t h e a c c el -
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engine during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestions. You achieve fuel sav-
ings even if standing time is as short as approx.
4 seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner, seat
heating or rear window defroster draw large
amounts of power and consume additional fuel.
Especially in city traffic and in stop and go driv-
ing they have a considerable impact. Therefore,
switch these functions off when they are not
really needed.
Have the vehicle serviced
Have the vehicle serviced regularly to achieve
good economy and a long vehicle life. BMW
recommends having the vehicle serviced at a
BMW center. Also note the BMW service sys-
tem, refer to page223.
General driving notes
Close the trunk lid/tailgate
Operate the vehicle only when the trunk
lid/tailgate and rear window are closed.
Otherwise, exhaust fumes could enter the inte-
rior of the vehicle.<
If the vehicle must be driven with the trunk lid/
tailgate open:
1.Close all windows and the glass roof.
2.Greatly increase the air volume of the auto-
matic climate control system, refer to
page98.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust tail pipes.
Otherwise, there is a risk of burns.<
Diesel particulate filter*
The diesel particulate filter collects soot parti-
cles and burns them periodically at high tem-
peratures. This cleaning process takes several
minutes. During cleaning, you may notice that
the engine temporarily runs less smoothly and
that a somewhat higher engine speed is neces-
sary to achieve the accustomed performance.
Also, noises may be heard and a slight amount
of smoke may emerge from the exhaust, even

Things to remember when driving
118 for a short period after the engine is switched
off.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page215.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise, greater
clutch wear will result.<
For more information about the drive-off assis-
tant, refer to page84.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page57.
Never drive with the clutch held down,
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.

When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. This can ultimately
result in a sudden blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals 1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.

Refueling
198 If you have refueled with the wrong fuel, contact
your BMW center.
The filler neck is designed for refueling at
diesel fuel pumps.
If the filler nozzle cannot be inserted into your
BMW's filler pipe, please ensure that you are
refueling at a diesel fuel pump and that it is
equipped with a diesel filler nozzle.<
In the event the Ultra-Low Sulfur Diesel
fuel cannot be fully inserted into the fuel
filler neck, please contact BMW Roadside
Assistance for instructions on how to add fuel.
For more information on BMW Roadside Assis-
tance, refer to page237.<
Winter diesel
To ensure that the diesel engine remains oper-
ational in the winter, please use winter diesel,
which is available at gas stations during winter
months. The fuel filter heating system, included
a s a s t a n d a r d f e a t u r e , p r e v e n t s d i s r u p t i o n o f t h e
fuel supply while driving.
Do not add additives, including gasoline;
otherwise, engine damage may occur.<
BMW Advanced Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxide
in the diesel emissions of your vehicle by means
of a mechanism that injects diesel exhaust fluid,
a reduction agent, into the exhaust tract. A
chemical reaction occurs in the catalytic con-
verter that minimizes the nitrogen oxide con-
tent.
To be able to start the engine as usual, a suffi-
cient amount of diesel exhaust fluid must be
present in a separate reservoir.
Warming the system
To warm the system to its operating tempera-
ture after starting with a cold engine, the auto-
matic transmission delays shifting to the next
higher gear, if necessary.
Reserve display
A display in the instrument cluster informs you
about the remaining distance you can drive with
the fluid remaining in the reservoir.
-
The reserve display appears beginning at
approx. 1,000 miles/1,600 km before the sup-
ply is used up.
When this reserve display appears in the
instrument cluster, have diesel exhaust
fluid refilled to avoid not being able to start the
engine.<
Diesel exhaust fluid at the minimum
level
Even if the display indicates -- mls, the engine
continues running if it is not switched off and if
all other requirements continue to be met, e.g. a
sufficient supply of fuel.
Do not drive to the end of the indicated
distance. Otherwise, it will not be possible
to start the engine again after switching it off.<
