Indicator and warning lamps 
 
Technology that monitors itself 
 
Indicator and warning lamps that are 
identified by 
 
l
 
 are tested for proper 
functioning whenever the ignition key is 
turned. They each light up once for 
different periods of time.
If a fault should occur in one of these 
systems, the corresponding lamp does 
not go out after the engine is started, or 
it lights up while the vehicle is moving. 
You will see how to react to this in the 
following section.
 
Red: stop immediately
 
Battery charge current
 
 
 
l
 
The battery is no longer being 
charged. Indicates a defective 
alternator drive belt or a problem with 
the alternator's charge circuit. Please 
contact the nearest BMW center.
If the drive belt is defective, stop 
and switch off the engine immedi-
ately to prevent overheating and 
serious engine damage. If the drive belt 
is defective, increased steering effort is 
also required.

Engine oil pressure
 
  
l
 
Stop the vehicle immediately 
and switch off the engine. 
Check the engine oil level and top off as 
required. If the oil level is correct, 
please contact the nearest BMW 
center.
Do not continue driving, as the 
engine could sustain serious 
damage from inadequate lubrication.

Brake warning lamp 
 
l 
 
If the lamp comes on when the 
parking brake is not engaged: 
check the brake fluid level. Before 
driving further, be sure to comply with 
the instructions on pages 106 and 118

In addition, an acoustic signal is 
sounded: a tire failure has occurred. 
Reduce vehicle speed immediately and 
stop the vehicle. Avoid hard brake 
applications. As you steer the vehicle, 
use caution and avoid overcorrecting.

If the indicator lamp comes on, 
there is a malfunction in the 
transmission system.
Bring the vehicle to a stop, select trans-
mission position "P", engage the 
parking brake  and switch the engine off 
(ignition key to position 0). 
Wait a few seconds, then start the 
engine.
If the indicator lamp goes out after a 
few seconds, normal transmission 
performance has been restored. Drive 
off normally.
If the indicator lamp does not go out, all 
selector lever positions can still be 
selected; however in the forward posi-
tions the vehicle has limited perfor-
mance as it drives only in 3
rd and 4
th 
gear.
If this happens, avoid extreme engine 
loads and consult the nearest BMW 
center.
Never work in the engine 
compartment when a drive gear 
(forward or reverse) is engaged. If you 
do this, the vehicle could move.<
For towing or jump-starting, refer to the 
information beginning on page 134.

lamps accompanied by a periodic 
clicking sound from the relay).To signal brieflyPress the lever up to but not beyond 
the detent. It then returns to the center 
position when released.
If the flashing of the turn signal 
indicators and the clicking from 
the relay are both faster than normal, 
one of the turn signal indicators has 
failed.<

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 
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 the engine speed 
and brake applications to the individual

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.<

Automatic recirculated-air control 
(AUC)
You can respond to unpleasant 
external odors or pollutants by 
temporarily stopping the flow of outside 
air. The system then recirculates the air 
currently within the vehicle. 
Press the button repeatedly to select 
one of three different operating modes.
>Indicator lamps off: outside air supply 
is on
>Left indicator lamp on Ð AUC mode: 
the system recognizes pollutants in 
the outside air and blocks the flow of 
air when necessary. The system then 
recirculates the air currently within 
the vehicle.
Depending on the air quality, the 
automatic system then switches back 
and forth between outside air supply 
and recirculation of the air within the 
vehicle
>Right indicator lamp on: the flow of 
external air into the vehicle is perma-
nently blocked. The system then 
recirculates the air currently within 
the vehicle.
If the windows fog over in the 
recirculated-air mode, switch the 
recirculated-air mode off and increase 
the air supply as required.<
Rear window defroster
When the rear window defroster 
is activated, the indicator lamp 
comes on. The rear window defroster 
switches off automatically.
At outside temperatures colder 
than approx. 39 7 (+4 6) the 
rear window defroster automatically 
assumes operation within 5 minutes 
after the engine is started.<
Draft-free ventilationYou can adjust the blower controls for 
the upper body area to obtain the 
optimum airflow rates and directions for 
your personal requirements:
1 Rotary dials for infinitely-variable 
opening and closing of the vent 
outlets
2 Selector levers for airflow direction
3 Rotary dial 3 allows you to control the 
temperature of the airflow from these 
outlets as desired

Lamps and bulbs Changing a wheelTailgate lamp5 watt bulb 
1. Pull out the bulb holder (arrow)
2. Replace the bulb.
Safety measures in the event of a 
flat tire or wheel change:
Stop the vehicle as far as possible from 
passing traffic. Park on a firm, flat, 
surface. Switch on the hazard warning 
flashers. Turn the steering wheel to the 
straight-ahead position and engage the 
steering lock. Shift into 1st or reverse 
(selector lever in Park with automatic 
transmission) and engage the parking 
brake.
All passengers should be outside the 
vehicle and well away from your imme-
diate working area (behind a guardrail, 
for instance).
If a warning triangle or portable hazard 
warning lamp is available, set it up on 
the roadside at an appropriate distance 
from the rear of the vehicle. Comply 
with all local safety guidelines and 
regulations.
Change the wheel only on a level, firm 
surface which is not slippery. Avoid 
jacking the vehicle on a soft or slippery 
support surface (snow, ice, loose 
gravel, etc.), as either the vehicle or the 
jack could slip sideways.
Position the jack on a firm support 
surface.
Do not place wooden blocks or similar 
objects under the jack. They could 
prevent the jack from extending to its 
full height and reduce its support 
capacity.
Do not lie under the vehicle or start the 
engine when the vehicle is supported 
by the jack Ð risk of fatal injury.<
Your BMW is equipped with a spare tire 
or a space-saver spare tire designed for 
temporary use in maintaining the 
vehicle's mobility in an emergency.
To remove the spare tire, lift the 
floor panel in the cargo area 
completely out, refer to page 99.<
