Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Attempt to vary both engine and vehicle
speeds, but refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100mphor 160km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
After 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Close the tailgate
Operate the vehicle only when the tail-
gate and rear window are closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle.<
If special circumstances make it absolutely nec-
essary to drive with the tailgate or rear window
open:
1.Close all windows and the glass sunroof.
2.Increase the air flow rate of the automatic
climate control considerably, refer to
page96.
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.<
Mobile phone in the vehicle
BMW discourages the use of mobile
communications devices, e.g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,

there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
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 page187.
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 handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Also use the drive-off assistant, refer to
page85.
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 page56.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no

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.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
With convenient access and automatic
transmission
Insert the remote control into the ignition
switch.
The engine can be switched off when the selec-
tor lever is in position N. Refer also to page36.
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. The ultimate result
can assume the form of a sudden blow-out.<
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 lbs.
passengers in your vehicle, the amount of
available 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.
