Alternative oil types
If approved oils are not available, you can add
quantities of up to 1 US quart/1 liter of another
oil with the following specifications:
Oil change
Oil changes should only be performed by a
BMW center.
Coolant
Coolant consists of half water and half additive.
Not all commercially availa
ble additives are suit-
able for your BMW. Ask your BMW center about
suitable additives.
Only use suitable a dditives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers. <
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives. <
Coolant temperature
If the coolant and therefore the engine over-
heats, a warning lamp lights up. A message
appears on the Control Display.
Checking coolant level
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns. <
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, th en 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.

Diagnosis OBD
On the drive r's side is a n OBD so cket f or 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 ce rtain 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 lights up if the fuel
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the fuel cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extr act form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.
