Indicator and warning lamps 
 
Technology that monitors itself 
 
The system runs an operational check 
on the indicator and warning lamps 
identified with the 
 
l
 
 symbol each time 
you switch on the ignition. 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 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; 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
Brake warning lamp for Cana-
dian models.

Flat Tire Monitor  
l
 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.
For additional information: refer to 
pages 78 and 80

Brake systemBrake fluid level If the brake fluid level is too low and 
brake pedal travel has become longer, 
there may be a defect in one of the 
brake system's hydraulic circuits.
Proceed to the nearest BMW 
center. It may be necessary to 
apply higher levels of pressure to the 
pedal when stopping and braking 
distances may also be longer. Please 
remember to adapt your driving style 
accordingly.
and operating conditions in which 
braking is restricted to gentle, low-
pressure applications will all increase 
the tendency for corrosion to form on 
the rotors; this is often accompanied by 
a simultaneous accumulation of 
contamination on the brake pads. The 
pads must exert a certain minimal level 
of pressure against the rotors for the 
disc brakes' inherent self-cleaning 
effect to remain effective; the pressure 
available under the above conditions 
may not provide adequate cleansing.
If the brake rotors are corroded, they 
will tend to respond to braking with a 
pulsating effect that even extended 
brake applications will fail to cure.
When driving in heavy rain and on wet 
roads it is a good idea to apply light 
pressure to the brake pedal every few 
miles. Monitor traffic conditions to 
ensure that this maneuver does not 
pose a hazard to you or to other road 
users. The heat generated in this 
process helps dry the pads and rotors 
to ensure that your brake system will 
respond with undiminished efficiency 
when you need it.
When descending steep hills and 
extended grades, downshift to a gear 
that will allow you to continue safely 
with only a minimal amount of braking. 
By minimizing the loads placed on the 
brake system, this strategy helps 
ensure that optimal brake system 
response will remain available at all 
times. Use care to avoid exceeding the 
approved engine-speed range, refer to 
page 66.Do not coast with the clutch 
depressed or with the transmis-
sion in neutral. Do not coast with the 
engine shut off. The engine provides no 
braking effect when the clutch is 
depressed and there is no power-assist 
for braking or steering when the engine 
is not running. 
BMW 325xi, 330xi: always refer all 
brake inspection and service work to 
your BMW center, as failure to observe 
the special procedures could result in 
damage to brake system components.
Never allow floor mats, carpets or any 
other objects to protrude into the area 
around the accelerator, clutch and 
brake pedals and obstruct their move-
ment.<
Brake pads
For your own safety: use only 
brake pads that the manufacturer 
has released for your particular vehicle 
model. The manufacturer cannot eval-
uate non-approved brake pads to 
determine if they are suited for use, and 
therefore cannot ensure the operating 
safety of the vehicle if they are 
installed.<

Brake fluidWarning lamp
The brake warning lamp comes 
on when the parking brake is 
not engaged: the brake fluid 
level is too low, refer to page 17.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for deter-
mining and correcting the cause of 
brake fluid loss, consult your BMW 
center. Your BMW center is familiar 
with the specifications for factory-
approved brake fluids (DOT 4).
Brake fluid loss results in extended 
pedal travel. Refer to the information on 
page 106.
Brake fluid is hygroscopic, that is, 
it absorbs moisture from the air 
over time.
In order to ensure the brake system's 
safety and reliability, have the brake 
fluid changed every two years at a 
BMW center, refer to page 67 and to 
the Service and Warranty Information 
Booklet (US models) or the Warranty 
and Service Guide Booklet (Canadian 
models).
Brake fluid is toxic and damages the 
vehicle's paint. You should always store 
it in original container and in a location 
which is out of reach of children.
Do not spill the fluid and do not fill the 
brake fluid reservoir beyond the MAX 
mark. The brake fluid could ignite upon 
contact with hot engine parts and 
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating 
the disposal of brake fluid.<
