Things to remember when driving
118
Things to remember when drivingBreak-in procedures To ensure that your vehicle continues to
furnish optimal economy of operation
throughout an extended service life, we
request that you devote careful attention to
the following section. Engine and differential The first 1,200 miles (2,000 km):
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
>4500 rpm and 105 mph (170 km/h)
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
After the first 1,200 miles (2,000 km) you
can gradually increase both engine and
vehicle speeds to their respective maxima.
You should also comply with these break-in
procedures if the engine or differential is
replaced at a later point. Tires Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. We thus urge you to drive
with extra care during the first 200 miles
(300 kilometers). Brake system Brakes require an initial break-in period of
approx. 300 miles (500 km) to achieve
optimal contact and wear patterns
between brake pads and rotors.
General driving notes High temperatures
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to
various sections of the exhaust system,
and never apply undercoating to them.
When driving, standing at idle and while
parking 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, and with it the risk of serious prop-
erty damage as well as personal injury.<
Parking the vehicle Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.Aquaplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
road surface. This phenomenon is referred
to aquaplaning, and is characterized by a
partial or complete loss of contact between
tires and road surface, ultimately under-
mining your ability to steer and brake the
vehicle.<
Water-covered streets
Do not drive through water on the
road if it is deeper than 1 foot (30 cm),
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the elec-
trical systems and the transmission may be
damaged.<

Brake system Braking with ABS The best way to achieve optimal response
from the ABS is to apply maximum pres-
sure to the brake pedal during emergencyÐ
panic stops. Since the vehicle maintains
steering responsiveness, you can never-
theless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Even light but
consistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.< Disc brakes
Driving in wet conditions While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to 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 You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's
braking effect by selecting a lower gear in
the automatic transmission's manual
mode, downshifting as far as first gear on
extremely steep stretches, refer to
page 68. This strategy helps you avoid
placing excessive loads on the brake
system.
Corrosion When the vehicle is driven only occasion-
ally, 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
minimal 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 appli-
cation will fail to cure.
Never allow the vehicle to coast with
the transmission in neutral Ð or with
the engine switched off; there is no engine
braking when the transmission is in neutral,
and no power-assist for brakes and
steering when the engine is not running.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.< Brake pads
If the brake pad wear indicator lamp
appears in the Check Control,
accompanied by a text: please take
careful note of the additional information in
the Control Display panel.
Warning lamp for Canadian models.
The brake pads have reached their
minimum pad thickness. Have them
replaced at your BMW center as soon as
possible.
For your own safety: use only brake
pads that BMW has released for your
particular vehicle model. Because BMW
cannot assess the suitability of other brake
pads for use on your vehicle, we are unable
to assume continued responsibility for the
vehicle's operating safety if non-approved
pads are installed.<

Refueling

Refueling Fuel filler door
Always switch off the engine before
refueling. If you do not, fuel cannot be
filled into the tank and a message in the
Check Control will appear.<
To open and close: press the rear edge of
the fuel filler door.
Manual release In the event of an electrical defect in the
system, you can release the fuel filler door
manually:
1.Lift the handle to remove the cover
panel on the right side of the luggage
compartment
2.Extract and then pull the handle with the
fuel pump symbol.
Always observe all applicable precau-
tions and regulations when handling
fuels. Never carry spare fuel containers in
your vehicle. Whether empty or full, these
containers can leak, cause an explosion,
and lead to fire in the event of a collision.<
Simple and environmentally friendly
When handling fuels always observe
any safety guidelines posted at the
filling station.<
Keep the filler cap in the bracket attached
to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling the
nozzle out of the pipe during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the
fuel-vapor recovery system.
The fuel tank is full when the filler nozzle
clicks off the first time.
Close the filler cap carefully after
refueling, continuing until you hear
the detent engage. While closing, be sure
not to pinch the strap between the cap and
the filler pipe. A loose or missing cap will
activate a message in the Check Control.<
Fuel tank capacity, approx. 23.2 US gallons
(88 litres), including the reserve capacity of
approx. 2.6 gallons (10 litres).
Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<

4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the disptick
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.
The space between the two marks on
the dipstick corresponds to approx.
1.1 US quarts (1 litre). Do not fill beyond
the upper mark on the dipstick. Excess oil
can damage the engine.

Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
BMW engines are designed to
operate without additives, and their
use could even lead to damage in some
cases. This also applies to the automatic
transmission, the differential and the power
steering system.<
Recommendation: have your oil changed at
your BMW center.
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come
into contact with oil should be thoroughly
washed with soap and water.
Always store oil, grease, etc., well out of
the reach of children; always observe all
warning labels on the containers.<
Please observe all environmental-
protection rules and regulations when
disposing of used oil.< Specified engine oils The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High
Performance Synthetic Oil, you can add
small amounts of another synthetic oil
between oil changes. Use only oils with the
API SH specification or higher. Ask your BMW center for details
concerning the specific BMW High
Performance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
Viscosity ratingsViscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.
To avoid the possibility of damage later on,
never use anything other than factory-
approved, nitrite and amino-free extended-
duty antifreeze with corrosion inhibitor.
Your BMW center is familiar with the official
specifications.
Antifreeze and anticorrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Extended-duty antifreeze with corrosion
inhibitor contains ethylene glycol Ð a flam-
mable substance. For this reason, do not
spill antifreeze with corrosion inhibitor on
hot engine parts. It could ignite and cause
serious burns.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used
extended-duty antifreeze with corrosion
inhibitor.<
