Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until the warning lamp lights
up in the instrument cluster, refer to page87, or
until the oil level monitor shows "+1.0".
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the warnings on
the containers. Otherwise, health hazards may
result.<
Oil change
Have your oil changed only by a BMW Center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW Center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or other approved syn-
thetic oils.
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Viscosity classes
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW Center knows
which additives are appropriate.
Only use approved additives, otherwise
the engine could be damaged. The addi-
tives are hazardous to health.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking the coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
Page 92 of 128

Under the hood
90 pressure to escape, then continue turning
to open.
3.The coolant level is correct if the upper end
of the red float spindle is at least at the same
level as the upper edge of the filler neck but
no more than 3/4 in or 2 cm above it, i.e. up
to the mark on the float spindle. 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.Twist the cap back on and tighten it firmly.
6.Have the cause for the coolant loss
removed as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights up although
the parking brake is not engaged:
Stop the vehicle immediately.
The brake fluid level in the reservoir is too low.
At the same time, you may notice that brake
pedal travel is longer. Have the system checked
as soon as possible.
If you continue driving, extended brake
pedal travel may be necessary and brak-
ing distances may be significantly longer. Be
sure to adapt your driving style accordingly.<
Canadian models display this warning
lamp.
Brake pads
The warning lamp lights up. The brake
pads have worn down to the minimum
safe limit. Have the brake pads
replaced as soon as possible.
For your own safety: only use brake pads
which BMW has approved for your spe-
cific vehicle model. BMW cannot evaluate non-
approved brake pads to determine if they are
suitable for use, and therefore cannot guaran-
tee the operating safety of the vehicle in the
event of their use.<

Maintenance
BMW Maintenance System
The BMW Maintenance System helps maintain
the road safety and operating reliability of your
BMW.
Regular maintenance is not only necessary for
the safety of your vehicle, but also plays a sig-
nificant role in maintaining the resale value of
your vehicle.
Service interval display
The BMW Maintenance System takes the vehi-
cle's operating conditions into account for the
service intervals:
From a maintenance point of view,
62,100 miles/100,000 km accumulated in
short-distance urban driving are not the same
as 62,100 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 6,210 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 and Warranty Information
Booklet for US models and Warranty
and Service Guide Booklet for
Canadian models
Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW Center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle’s Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<
Socket for On-Board
Diagnosis OBD
Vehicle components that are relevant to the
composition of exhaust emissions can be
checked with a device via the OBD socket.
This socket is located on the driver's side to the
left, on the bottom of the instrument panel
underneath a cover.

Exhaust emission values
The warning lamp lights up: the
exhaust emission values have wors-
ened. Have the car checked as soon as
possible.
The lamps flash under certain conditions. This
indicates excessive misfiring of the engine. If
this happens, you should reduce your speed
and visit your nearest BMW Center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
Canadian models display this warning
lamp.
If the gas cap is not properly tightened,
the OBD system will assume that fuel
vapor is escaping. An indicator will then light up.
If the cap is then tightened, the indicator will go
out within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have
signed a subscription contract for BMW Assist,
certain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore, be handled carefully. BMW recommends hav-
ing your BMW Center perform any work that
you do not feel competent to perform yourself
or that is not described here.
Do not touch the glass portion of a new
bulb with your bare hands since even
small amounts of impurities burn into the sur-
face and reduce the service life of the bulb. Use
a clean cloth, paper napkin or a similar material,
or hold the bulb by its metallic base.<
A replacement bulb set is available from your
BMW Center.
When working on electrical systems,
always begin by switching off the corre-
sponding consumers, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, be sure to
observe any instructions provided by the bulb
manufacturer.<
For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
If the routine for changing a particular
bulb is not described here, please contact
your BMW Center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LEDs
Control elements, display units and other inte-
rior equipment in your vehicle use a light-emit-
ting diode behind a cover as a light source.
These light-emitting diodes, which operate
using a concept similar to that applied in con-
ventional lasers, are officially designated as
Class 1 light-emitting diodes.
Do not remove the covers, and do not
look directly at the unfiltered light for sev-
eral hours. Otherwise, your eyes could suffer
irritation of the retina.<

Xenon lamps*
These bulbs have a very long service life and are
unlikely to fail. If one of these bulbs should nev-
ertheless fail, it is possible to continue driving
with great caution using the fog lamps, provided
traffic laws in your area do not prohibit this.
Have work on the xenon lighting system
performed only by your BMW Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high electrical voltages
present, there is a risk of potentially fatal acci-
dents if work is performed inappropriate.<
