Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance to the forward vehicle. A defensive
and smooth driving style keeps fuel con-
sumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accele rate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable ge ar 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 lig ht, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
On a downhill slope, take your foot off the accel-
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engi ne during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestion. 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 and the
seat or rear window heating draw large amounts
of power and consume a dditional fuel. Espe-
cially in city traffic and in stop and go driving
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 page 202.
General driving notes
Close the luggag e compartment lid
Operate the vehicle only when the lug-
gage compartment lid is closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle. <
If the vehicle must be driven with the luggage
compartment lid open:
1. Close all windows.
2. Greatly increase the ai r volume of the auto-
matic climate control system, refer to
page 96.
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 sect ions of the exhaust sys-
tem, and never apply un dercoating 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 ho t exhaust tail pipes.
Otherwise there is a risk of burns. <
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.<

Things to remember when driving
112
The risk of hydroplaning
increases with declin-
ing tread depth on the tire s, refer also to Mini-
mum tread depth on page 194.
Driving through water
Drive though calm water only if it is not
deeper than 1 ft/25 cm and at this height
no faster than walking speed, up to 6 mph/
10 km/h. 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. Ot herwise greater clutch
wear will result. <
For more information about the drive-off assis-
tant, refer to page 80.
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 pre ssure 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. Full
braking efficiency will th en 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 br aking is required. Even light but consistent brak
e 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 page 54.
7-gear sport automatic transmission with
dual clutch: Never drive with the trans-
mission 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.
Manual transmission: Never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
engine braking action will not be present or
there will be no power a ssistance to the brakes
or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise peda l function could be
impaired. <
Corrosion on brake rotors
When the vehicle is driv en only occasionally,
during extended periods when the vehicle is not
used at all, and in op erating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts 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 re spond with a pulsating
effect that even extended application will fail
to cure.
When the vehicle is parked
Condensation forms wh ile the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.

Word-matching principle
The system's word-matching principle makes it
easier for you to enter the names of towns or
streets. The system runs ongoing checks, com-
paring your destination entries with the data
stored in the vehicle as the basis for instant
response. The benefits for you include:
> Names of towns entered may differ from the
official versions if you are using a spelling
that is customary in another country.
Example:
Instead of the German spelling "München"
you can also enter the English spelling
"Munich" or the Italian spelling "Monaco".
> When you are entering the names of towns
and streets the system will complete them
automatically as soon as enough letters are
available to ensure unambiguous identifi-
cation.
> The system offers only those letters for
selection of name entries that are stored in
the vehicle. Thus, entry of erroneous or
unregistered names is impossible.
