Engine oil
The engine oil consumption is dependent on 
driving style and driving conditions.
Checking the engine oil level with the 
dipstick*
1.Park the vehicle on a level surface with the 
engine at operating temperature, i.e. after 
an uninterrupted drive of at least 6.5 miles/
10 km.
2.Switch off the engine.
3.After approx. 5 minutes, pull out the 
dipstick5 and wipe it off with a lint-free 
cloth, paper towel or similar material.
4.Carefully push the dipstick all the way back 
into the measuring tube and pull it out again. 
The oil level must be between the two 
markings on the dipstick.
The oil quantity between the two markings on 
the dipstick is equivalent to approx. 1 US quart/
1liter. 

Under the hood
220 The oil level must not be above the upper 
marking of the dipstick. Too much oil will 
harm the engine.<
Checking the engine oil level 
electronically*
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, i.e. 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.Push button 1 in the turn indicator lever up 
or down repeatedly until the appropriate 
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button 2 in the turn indicator lever. 
The oil level is checked and the reading dis-
played.
Possible displays

Specified engine oils
Your service center can advise you on which 
engine oils have been approved by the manu-
facturer of your vehicle.
The engine oil quality is critical for the life of the 
engine.
Approved oils can be identified by the following 
specification:
Approved oils belong to the following viscosity 
classes: SAE 0W-40, SAE 0W-30, SAE 5W-40 
and SAE 5W-30.
Alternative oil types
If the approved engine oils are not available, up 
to 1 US quart/1 liter of another oil with the fol-
lowing specification may be used:
API SM or higher
Coolant
Do not add coolant to the cooling system 
when the engine is hot. Escaping coolant 
can cause burns.<
Coolant consists of half water and half additive. 
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for 
suitable additives.
Only use suitable additives; otherwise, 
engine damage may result. Because 
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the 
engine has cooled down.
2.Turn the cap of the expansion tank a little 
counterclockwise to allow any accumulated 
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.

BMW Maintenance System
The BMW Maintenance System supports the 
preservation of the traffic and operating safety 
of your BMW. The objective is to optimize 
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
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 page73:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>Vehicle check
>Legally mandated inspections depending 
on local regulations
>Diesel particulate filter
*
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 page76; otherwise, the 
effectiveness of Condition Based Service CBS 
is not assured.<

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

Socket for Onboard 
Diagnosis OBD
On the driver's side is an OBD socket for check-
ing components relevant to the composition of 
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have 
the car checked as soon as possible.
Canadian models display this warning 
lamp.
The lamp flashes under certain conditions. This 
indicates excessive misfiring in 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.
The warning lamp comes on if the gas 
cap is not properly tightened and the 
OBD system assumes that fuel vapor 
is escaping. Make sure that the gas cap is cor-
rectly positioned and close it until it audibly 
clicks.
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 service contract for BMW Assist, cer-
tain vehicle data may be transmitted or 
recorded in order to facilitate the corresponding 
services.
