Cleaning windshield and headlamps*
Pull lever 4.
Washer fluid is sprayed onto the windshield and
the wipers are operated for a short time.
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do, your vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid.
Do not use the washers when the washer fluid
reservoir is empty, otherwise you will damage
the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
automatically while the engine is running or the
ignition switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in the tightly closed
original container, well out of the reach of chil-
dren. Comply with the instructions on the con-
tainer.<
Washer fluid reservoir
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving
conditions are unfavorable for driving at a
constant speed. Otherwise you could lose con-
trol of the vehicle and cause an accident as a
result. Unfavorable driving conditions include,
for example, winding roads, heavy traffic or a

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, e.g. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
Display in the instrument cluster
1.Lightly push button 1 in the turn indicator
stalk up or down repeatedly until the appro-
priate symbol is shown in the display,
accompanied by the word "OIL".
2.Press button 2 in the turn indicator stalk.
The oil level is checked and the reading dis-
played.

Under the hood
202 pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
Brake system
Malfunctions
Brake fluid
The warning lamps light up in red
even though the handbrake has been
released. A message appears on the
Control Display. Stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system checked without
delay.
Display of this malfunction on Cana-
dian models.
If you continue to drive the car, you may
have to depress the brake more and brak-
ing distances may be significantly longer.
Please adapt your driving style accordingly.<
Brake pads
The warning lamps light up in red
even though the handbrake has been
released. A message appears on the
Control Display. The brake pads have
reached the safe limit for pad wear. Have brake
pads replaced immediately.
Display of this malfunction on Cana-
dian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. BMW is unable to
assess the suitability of brake pads it has not
approved and therefore cannot guarantee their
safety.<

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air. The
objective is to optimize efforts with respect to
minimal vehicle maintenance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page74:
>Engine oil
>Brakes: separately for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs
>Vehicle check>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page78; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<

Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
