Indicator and warning lamps 
 
Technology that monitors itself 
 
Many of the systems of your BMW 
monitor themselves automatically, both 
during engine starts and while you are 
driving. Indicator and warning lamps 
that are identified by "
 
l
 
" are tested for 
proper functioning whenever the igni-
tion 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 below.
 
Red: Stop immediately
 
Battery charge 
 
l
 
 
The battery is no longer being 
charged. There is a malfunction 
of the alternator ribbed V-belt or in the 
charging circuit of the alternator. Please 
contact the nearest BMW center.
If the ribbed V-belt is defective, do 
not continue driving. If you do so, 
the engine could be damaged due to 
overheating. If the ribbed V-belt is de-
fective, increased steering effort is also 
required.<
Engine oil pressure l 
Stop the vehicle and switch off 
the engine immediately. Check 
the engine oil and top up as required. If 
the oil level is correct, please contact 
the nearest BMW center.
Do not continue driving. If you do 
so, the engine could be damaged 
because of inadequate lubrication.< 
Tire Pressure Control (RDC)
* l
In addition, an acoustic signal is 
sounded: A tire failure has oc-
curred. Reduce vehicle speed immedi-
ately and stop the vehicle. Avoid hard 
brake applications. Do not oversteer. 
For additional information: Refer to 
page 80.

Automatic transmission with Steptronic
*
In the following situations, the Step-
tronic "thinks" for you in the manual 
mode:
>In order to prevent the engine from 
overrevving, the transmission shifts 
automatically to the next higher gear 
just before the RPM cutoff point.
>If you do not do anything to inter-
vene, it will automatically downshift 
at lower speeds.
>In kickdown, it will downshift into 
the lowest gear possible, depending 
on the engine speed.
>According to the situation, for in-
stance in wintry conditions, the 
vehicle can be started in 2nd or 
3rd gear.

Electronic transmission control 
module
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," set the parking 
brake and turn 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 per-
formance has been restored. You may 
continue to drive as usual.
If the indicator lamp does not go out, 
you can place the selector lever in all 
positions. However, the vehicle will now 
only operate in 3rd and 4th gear.
If this happens, avoid extreme engine 
loads and consult the nearest BMW 
center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do 
this, the vehicle could move.<
For towing, tow-starting or jump-start-
ing the vehicle, refer to the information 
beginning on page 157.

Fuel gauge  Temperature gauge  Service Interval Display When you switch on the ignition, the in-
dicator lamp comes on briefly to con-
firm that the system is stationary. 
Once the indicator lamp begins to light 
up continuously, there are still approx. 
2.1 gallons (8 liters) of fuel in the fuel 
tank.
Tank capacity: page 175.
If the tilt of the vehicle varies (extended 
driving in mountainous areas, for exam-
ple), there may be slight fluctuations of 
the needle.
Fill the fuel tank well before it is 
empty. Driving to the last drop of 
fuel can result in damage to the engine 
and/or the catalytic converter.<460us081

The next service due appears with the 
message OILSERVICE or INSPECTION, 
together with the remaining distance 
before scheduled service.
The computer bases its calculations of 
the remaining distance on the rate of 
fuel consumption in the period immedi-
ately preceding your data request.
A flashing message and a "Ð" in front of 
the number mean that the service inter-
val has already been exceeded by the

Dynamic Stability Control (DSC) The 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, the system recog-
nizes unstable vehicle conditions (un-
dersteering or oversteering, for example) 
and holds the vehicle on a sure course 
by intervening via the engine and by 
braking intervention at the individual 
wheels. 
The system activates automatically each 
time you start the engine.462us284
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly 
after you switch on the ignition. 
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is actively regulating drive 
torque in response to monitored vehicle 
operating conditions.
If the indicator lamp fails to go out after 
the engine is started, or comes on dur-
ing the course of normal vehicle opera-
tion:
If the system was not switched off, 
there is a system malfunction. The vehi-
cle remains operational, but without 
DSC. Please consult your BMW center 
for repairs.
To deactivate the systemPress the button. The indicator lamp 
flashes.
The illustration depicts the arrangement 
of the buttons if the vehicle is fully 
equipped. This may vary, depending on 
the equipment actually installed.
When the DSC is deactivated, you are 
operating the vehicle in the conven-
tional drive mode.
In exceptional instances, it is effective 
to deactivate the system:
>when rocking the vehicle or starting 
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 110.To reactivate the systemPress the button again; the indicator 
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss 
due to excessive vehicle speed remain 
the responsibility of the driver. For this 
reason, do not take risks by using the 
additional safety margin provided by 
the system as an excuse.<
For additional details concerning DSC, 
please refer to the chapter describing 
"Advanced technology" on page 163.

Automatic climate control Air supply
 
By pressing the left or right half 
of the button, you can vary the 
air supply. By doing this, you switch off 
the automatic control of the air supply. 
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed 
by pressing the left half of the button, 
all of the displays are canceled: The 
blower, heating and air conditioner are 
switched off, and the air supply is 
stopped. You can reactivate the system 
by pressing any button of the automatic 
climate control.
To defrost the windshield and 
side windows 
This program quickly removes 
ice and condensation from the 
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the 
temperature setting Ð rewarmed when 
the air conditioner system is switched 
on.
Depending on the weather, the wind-
shield may fog over briefly when the 
engine is started.
Switch off the air conditioner at outside 
temperatures below approx. 42 7 
(5 6). This will help to prevent the win-
dows from fogging up. 
If the windows fog over after switching 
the air conditioner off, switch it back 
on.
Condensation forms in the air 
conditioner system during opera-
tion, which then exits under the vehicle. 
Traces of condensed water of this kind 
are thus normal.<
Automatic recirculated air control 
(AUC)
You can respond to unpleasant 
external odors by temporarily 
blocking the outside air. The system 
then recirculates the air already within 
the vehicle. By repeated actuation of 
the button, you can select one of three 
different operation modes.
>Indicator lamps off: Fresh air flows 
into the vehicle
>Left-hand indicator lamp on Ð AUC 
mode: The system detects pollutants 
in the outside air and responds by 
deactivating the outside air flow as 
required. The system then recircu-
lates the air already within the 
vehicle.
Depending on air quality require-
ments, the system automatically 
switches between outside air supply 
and recirculation of the air already 
within the vehicle.
>Right-hand indicator lamp on: The 
flow of outside air is permanently 
blocked. The system recirculates the 
air already within the vehicle.
If the windows fog over in the 
recirculated air mode, switch this 
mode off and increase the air supply as 
required.<

Clothes hooks:
When suspending clothing from the 
hooks, be sure that they will not ob-
struct the driver's vision. Do not hang 
heavy objects on the hooks. If you do 
so, such objects could pose the risk of 
personal injury during braking or eva-
sive maneuvers.
use with unleaded fuel only.
Even minute quantities of lead would be 
enough to permanently damage both 
the catalytic converter and the system 
oxygen sensor.
To ensure efficient, trouble-free engine 
operation and avoid potential damage:
>Be sure to comply with the scheduled 
maintenance requirements.
>Fill the fuel tank well before it is 
empty.
>Tow-start only when the engine is 
cold. If you attempt to tow-start with 
a warm engine, unburned residual 
fuel in the catalytic converter could 
ignite and cause damage. It is better 
to jump-start the vehicle with outside 
assistance.
>Avoid other situations in which the 
fuel is not burned, or burns incom-
pletely, such as engaging the starter 
frequently or for extended periods, or 
repeated start attempts in which the 
engine does not start (stopping and 
restarting an engine which is running 
properly does not present a problem). 
Never allow the engine to run with 
any of the spark plug cables discon-
nected.Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic 
convertor. If you do not, the catalytic 
converter could respond by overheat-
ing, leading to serious damage.
Extreme temperatures occur at the cat-
alytic converter on this and every cata-
lyst-equipped vehicle. Heat shields are 
installed adjacent to some sections of 
the exhaust system. Never remove 
these shields; do not apply undercoat-
ing to their surfaces. When driving, 
standing at idle, and parking the vehi-
cle, take extra care to avoid contact be-
tween the exhaust system and flamma-
ble materials (grass, hay, leaves, etc.). 
Such contact could lead to a fire, re-
sulting in serious personal injury and 
property damage.

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather. 
Adaptations in driving style should be 
accompanied by preparations on the 
vehicle itself to ensure that your 
progress through the winter remains 
safe and trouble-free.CoolantBe sure that the coolant mixture con-
tains the year-round ratio of 50:50 
water and extended-duty antifreeze/
corrosion protection. This mixture pro-
vides protection against freezing down 
to approx. Ð 34 7 (Ð 37 6). Replace 
the coolant every four years.LocksBMW door lock deicer can be used to 
free them if frozen. This deicer also 
contains lubricant.
After its use, treatment with BMW lock 
barrel grease is recommended.Rubber seals and components To prevent the weather-stripping from 
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood 
and luggage compartment lid seals.

Snow chains BMW snow chains
* can be mounted on 
both summer and winter tires. Mount 
them in pairs on the rear wheels only 
and comply with the manufacturer's 
safety precautions. Do not exceed a 
maximum speed of 30 mph (50 km/h). 
For best performance, deactivate the 
DSC when snow chains are mounted. 
Refer to page 79.
Starting offWhen starting from a full stop in deep 
snow or for "rocking" the vehicle to free 
it, we recommend that you deactivate 
the DSC system. Refer to page 79.Driving on low-traction road 
surfacesUse smooth, gentle pressure to control 
the accelerator pedal. Avoid excessive 
engine speeds and shift to the next 
higher gear at an early point. On down-
grades or slopes, shift down to the next 
lower gear at an early point. Maintain an 
adequate distance between yourself 
and the car ahead.
BrakesWinter road conditions substantially re-
duce the traction available between the 
tires and the road surface. Remember 
that braking distances will be signifi-
cantly longer as a result.
ABS is intended to prevent the wheels 
from locking during brake applications, 
thus helping to maintain vehicle stability 
and steering response.
If the ABS does not respond in a critical 
braking situation and the wheels lock: 
Reduce the pressure on the brake pedal 
until the wheels just start to roll again 
while still maintaining enough force to 
continue braking. 
Following that, increase pedal pressure 
again. Reduce the pressure as the 
wheels lock, then reapply pressure. 
Repeat this procedure. This type of 
staggered braking will reduce the brak-
ing distance, and the vehicle still re-
mains responsive to steering. It allows 
you to steer around hazards once you 
have reduced the pressure on the brake 
pedal.
