Central locking system
The concept
The central locking system functions when the
driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
> Luggage compartment lid
> Fuel filler door
> Center armrest
*
Operating from outside
>Via the remote control
> Using the door lock
> In cars with convenient access
*, via the
handles on the driver's and passenger's
doors
In addition, if the remo te control is used, the
welcome lamps, interior lamps and the door's
courtesy lamps
* are switched on or off. The
alarm system
* is also armed or disarmed.
For further details of the alarm system,
refer to
page 33.
Operating from inside
By means of the button for central locking, refer
to page 32.
In the event of a sufficiently severe accident, the
central locking system un locks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle
could lock the doors from the inside. You
should therefore take the remote control with
you when you leave the ve hicle so that the latter
can be opened from outside. <
To operate the retractable hardtop with
the remote control, the doors and lug-
gage compartment lid must be closed and the
cargo bay partition must be folded down and
engaged on both sides. Refer also to page38.<
Unlocking
Press the button.
The interior lamps, the courtesy lamps
* and the
welcome lamps come on.
Setting unlocking characteristics
You can set whether only the driver's door or
the entire vehicle is to be unlocked when the
button is pressed for the first time.

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control
Display.
Check coolant level, refer to page201.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 210 7/100 6 and approx. 300 7/
150 6.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14.5 US gallons/
55 liters.
You can find information on refueling on
page 188.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control
Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur. <

Things to remember when driving

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
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Do not drive with full-throttle operation, and do
not use the transmission 's kick-down mode or
Launch Control.
After driving 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 no t achieve their full trac-
tion potential until afte r 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 clut ch reaches its optimal
level only after a distan ce 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 renewe d in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight incr eases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove additional mirrors and the luggage rack
when they are no longer in use. Mounted parts
affect the vehicle's aerodynamics and increase
fuel consumption.
Close both windows
An open glass roof or window causes higher air
resistance and thus increases fuel con-
sumption.
Check tire inflation pressure regularly
Check the tire inflation pr essure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine wa rm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.

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.<
