For your own safety
 
Use unleaded gasoline only. Fuels  
containing up to and including 
10 % ethanol or other oxygenates with 
up to 2.8 % oxygen by weight (i.e. 
15 % MTBE or 3 % methanol plus an 
equivalent amount of co-solvent) will 
not void the applicable warranties 
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel 
quality (volatility, composition, addi-
tives, for example) among gasolines 
offered for sale in the United States and 
Canada. The use of poor-quality fuels 
may result in driveability, starting and 
stalling problems especially under 
certain environmental conditions, such 
as high ambient temperature and high 
altitude.
Should you encounter driveability prob-
lems which you suspect could be 
related to the fuel you are using, we 
recommend that you respond by 
switching to a recognized high-quality 
brand.
Failure to comply with these recom-
mendations may result in unscheduled 
maintenance.
Obey all applicable safety rules when 
you are handling gasoline.

Rear windowTo closeThe handle recesses in the interior trim 
panel of the tailgate (arrows) make it 
easier to pull the lid down.
Both before starting off and after 
completing every journey, check 
the rear window or the tailgate to 
ensure that it has not been opened 
inadvertently.<
To avoid injuries, be sure that the 
travel path of the tailgate is clear 
when it is closed, as with all closing 
procedures.<
Always drive with both the tailgate 
and the rear window securely 
closed, as exhaust gases might other-
wise be drawn into the interior of the 
vehicle. Should it be absolutely neces-
sary to operate the vehicle with the tail-
gate or rear window open:
>Close all windows. Shut the sliding/
tilt sunroof
>Sharply increase the air supply for the 
air conditioning or automatic climate 
control, refer to page 85 or 88.<
To open from outsideSmall items can be loaded or unloaded 
quickly if the rear window is opened 
separately.
Press the button (arrow): the rear 
window opens slightly. It can now be 
tilted up.
Opening with the remote control, refer 
to page 30.
Push the window down to close it.
If pointed or sharp-edged objects 
could strike the rear window while 
driving, be sure to provide protection 
around all edges. If you do not do this, 
the heating conductors of the rear 
window could be damaged.<

Automatic transmission with Steptronic
*
N  NeutralSelect only when stopping for an 
extended period.D  Drive (automatic shift program)This position is designed for driving 
under all normal operating conditions. 
All forward gears are available.KickdownIn the kickdown mode, you achieve 
maximum acceleration and in 
position D top speed.
Depress the accelerator pedal past the 
increased resistance point at the full-
throttle position.
M/S Manual mode and
Sport ProgramMove the selector lever from D to M/S 
to activate the Sport Program; SD 
appears in the display panel. The M/S 
mode is recommended for perfor-
mance-oriented driving.
Once in the M/S mode you can tap the 
selector lever to switch the automatic 
transmission from the Sport Program to 
its manual selection mode.
This mode allows you to execute 
upshifts manually by tapping the lever 
toward "+", while downshifts are 
selected by tapping in the "Ð" direction. 
The displays M1 through M5 appear in 
the display panel to indicate your 
current gear selection.
The Adaptive Transmission Control 
(ATC) executes upshifts and downshifts 
only when the new gear will provide a 
suitable combination of engine and 
road speed, for example ATC will not 
execute downshifts if the engine speed 
is too high.  The desired, then the actual 
gear, briefly appear in the instrument 
cluster.
To accelerate quickly in the 
manual mode (to pass another 
vehicle), shift down manually or employ 
the kickdown mode.<
Shifting from M/S to the selector lever 
positions P, R and N is possible only by 
going through D.

Dynamic Stability Control (DSC)
* Ð BMW 325i
The conceptThe Dynamic Stability Control (DSC) 
maintains vehicle stability, even in crit-
ical driving situations.
The system optimizes vehicle stability 
during acceleration and when starting 
from a full stop, as well as optimizing 
traction. In addition, it recognizes 
unstable vehicle conditions, such as 
under- or oversteering, and, as far as is 
possible within the laws of physics, 
helps keeping the vehicle on a steady 
course by reducing engine speed and 
brake applications to the individual 
wheels.
DSC is operational every time you start 
the engine. DSC incorporates the func-
tionality of the Automatic Differential 
Brake (ADB) and the Cornering Brake 
Control (CBC).
ADB (Automatic Differential Brake) 
relies on selective braking applications 
at the drive wheels to furnish the func-
tionality of a conventional limited-slip 
differential for enhanced traction in crit-
ical driving conditions such as those 
encountered on snow-covered road 
surfaces, etc.
The ADB is in standby mode when DSC 
is switched off.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly 
after the ignition has been 
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC controls the drive and braking 
forces. 
The indicator lamp stays lit:
DSC has been switched off via the 
button; ADB is operational.
ADB control intervention is not indi-
cated.
The indicator lamp and the 
brake warning lamps remain on 
continuously:
The DSC, ADB and DBC have 
been switched off via the button 
or are defective.
The vehicle will remain completely 
operational, however, without DSC. In 
the event of a fault, please see your 
BMW center, refer to pages 18, 19.
Indicator and warning lamps for 
Canadian models.
To switch DSC off/activate ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is switched off; ADB is opera-
tional.
In the following rare situations, it may 
be effective to activate the ADB for a 
brief period:
>When rocking the vehicle or starting 
off in deep snow or on loose surfaces
>When driving on snow-covered 
grades, in deep snow, or on a snow-
covered surface that has been 
packed down from being driven on
>When driving with snow chains.
Traction is increased by deactivating 
the control systems that enhance trac-
tion under normal conditions.

Dynamic Stability Control (DSC) Ð BMW 325xiThe conceptDSC maintains vehicle stability, even in 
critical driving situations.
The system optimizes vehicle stability 
during acceleration and when starting

DSC is operational every time you start 
the engine. DSC includes the functions 
of ADB-X and CBC.
The Automatic Differential Brake 
(ADB-X) enhances traction in critical 
situations (such as those encountered 
on snow-covered roads) by using 
selective braking intervention to replace 
the limited-slip functions executed by 
the differential and transfer case in 
conventional drivetrains.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly 
after the ignition has been 
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC controls the drive and braking 
forces. 
The indicator lamp stays lit: 
DSC has been switched off via the 
button; ADB-X is operational.
ADB-X control intervention is not indi-
cated.
If the indicator lamp fails to go out 
when you press the DSC button, 
this indicates a malfunction in the DSC 
and ADB-X systems; the stability 
enhancement functions described on 
the left are no longer available.<
The vehicle will remain completely 
operational, however, without DSC. In 
the event of a malfunction, please 
consult your BMW center, refer to 
pages 18, 19.
To deactivate DSCPress the DSC button briefly, the indi-
cator lamp comes on and remains lit.
DSC is switched off, and ADB-X reverts 
to its maximum torque-transfer mode.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting 
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability, 
always drive with the DSC 
switched on whenever possible.<
