Service interval display
Remaining distance to next service
The displays shown in the illustration appear for
a few seconds when the ignition key is in
position 1 or after the engine is started.
The next service due appears with the message
OIL SERVICE or INSPECTION, together with
the distance remaining in miles – in kilometers
in Canada – before the next scheduled service.
The computer bases its calculations of the
remaining distance on the preceding driving
style.
A flashing message and a minus sign in front of
the number mean that the service interval has
already been exceeded by the distance shown
on the display. Please contact your BMW center
for an appointment.
Outside temperature
If the vehicle is not equipped with a computer,
the display in the instrument cluster always
shows the outside temperature.

Washer fluids for washer
systems
Headlamp* and windshield washer
system
Capacity of windshield washer system: approx.
3.2 quarts/3 liters.
Capacity when equipped with headlamp
washer system: approx. 5.3 quarts/5 liters.
Fill with water and, if required, with an antifreeze
agent according to the manufacturer's recom-
mendations.
We recommend that you mix the washer
fluid before adding it to the reservoir.<
Antifreeze agents for the washing sys-
tems are highly flammable. For this rea-
son, keep them away from sources of flame and
store them only in their original containers.
Store them so that they are inaccessible to chil-
dren. Comply with the instructions on the con-
tainers.<

driving style and vehicle operating conditions.
Warning lamp

The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top up if necessary. If the oil level is correct,
please contact the nearest BMW center.Do not continue driving, as the engine
could sustain serious damage from inad-
equate lubrication.<
Engine oil level
The warning lamp lights up in yellow
while driving:
The oil level is at the absolute mini-
mum; refill as soon as possible. Do not drive
more than 30 miles/50 km before refilling.
The warning lamp lights up in yellow
after the engine has been switched off:
Add engine oil at the earliest opportu-
nity, e.g. when you stop to refuel.
Engine oil sensor
The warning lamp lights up in yellow
within 20 seconds after the engine is
started:
The oil level sensor is defective. Please have it
checked by a BMW center.
Checking the oil level
1.With the vehicle's engine at normal operat-
ing temperature, i.e. after uninterrupted
driving for at least 6 miles/10 km, park the
vehicle on a level surface
2.Switch off the engine
3.After approx. 5 minutes, pull the dipstick
out and wipe it off with a clean lint-free
cloth, paper towel, or similar material
4.Carefully push the dipstick all the way into
the guide tube and pull it out again
5.The oil level should be between the two
marks on the dipstick

Maintenance
The BMW Maintenance
System
The BMW Maintenance System helps maintain
the road safety and operating reliability of your
BMW.
Please keep in mind that regular maintenance is
not only necessary for the safety of your vehi-
cle, but also plays a significant role in maintain-
ing the resale value of your vehicle.
Service interval display
While conventional systems rely on distance
traveled alone to determine when a service is
due, the BMW Maintenance System has taken
the actual conditions under which the vehicle is
operated into consideration for years, because
miles can be traveled in many different ways:
From a maintenance point of view,
60,000 miles/100,000 km accumulated in
short-distance urban driving are not the same
as 60,000 miles/100,000 km accumulated at
moderate cruising speeds in long-distance
highway travel.
The BMW Maintenance System includes the
Engine Oil Service and Inspections I and II.
Determining the maintenance intervals based
on the actual loads on the vehicle covers every
kind of operating situation. Minimal use drivers,
who drive fewer than about 6,200 miles/
10,000 km per year, should nevertheless have
the oil changed at least every 2 years since
engine oil deteriorates over time, regardless of
use.

Service Guide Booklet for Canadian
models
For additional information on required mainte-
nance intervals and procedures, please refer to
the Service and Warranty Information Booklet
for US models, or the Warranty and Service
Guide Booklet for Canadian models.
Depending on operating conditions, it may be
advisable to have the body checked for damage
from rocks or gravel as a precaution against cor-
rosion.
BMW recommends that you have your
BMW center perform the maintenance
and repair.
Be sure that all maintenance work is recorded in
the Service and Warranty Information Booklet
for US models, Warranty and Service Guide
Booklet for Canadian models. These entries will
serve as proof that the vehicle has received reg-
ular maintenance.<
