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 precise measurement and display of the oil
level, the engine must be at operating tempera-
ture, i.e. following at least 6.2 miles/10 km of
uninterrupted driving. 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.

until a corresponding message is shown
on the Control Display. Add oil within the next
125 miles/200 km; otherwise, the engine could
be damaged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil grades
Do not use any oil additives; otherwise,
you may cause engine damage.<
Approved engine oils
You BMW center will be happy to advise you
about the engine oils approved by the manufac-
turer of your vehicle.
The engine oil grade is a decisive factor for the
service life of the engine.
Approved engine oils can be found in the fol-
lowing specification:
Approved engine oils belong to the viscosity
classes SAE 0W-40, SAE 0W-30, SAE 5W-40,
and SAE 5W-30.
Alternative oil grades
If approved oils are not available, you can use
quantities of up to 1 US quart/1 liter of another
oil with the following specifications:
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.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<

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.

Maintenance
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 page72:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>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 page75; otherwise, the
effectiveness of Condition Based Service CBS
is not assured.<

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 condi-
tions. 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 memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extract 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.

Care
Care products
Regular cleaning and care contributes signifi-
cantly to the value retention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material tested, laboratory checked and
proven in the field, and offer optimal care and
protection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles.<
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage.<
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and brake discs can corrode.<
Automatic car washes
Preference should be given to cloth car washes.
Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows.<
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
>Dimensions of your vehicle, refer to
page227.
>If necessary, fold in the outside rearview
mirrors, refer to page50.
>Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts.<
>In Convertibles, do not treat the convertible
top with wax. Ensure that a program is avail-
able that does not apply wax or is designed
specifically for convertibles.
Preparations before driving into an automatic
car wash:
>Unscrew the rod antenna
*.
>Deactivate the rain sensor
* to prevent unin-
tentional wiping.
>Remove additional attachments, e.g. spoil-
ers or telephone antennas, if there is a pos-
sibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Move the selector lever to position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.

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.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW center.Only change bulbs when cool; otherwise,
you may burn yourself.<
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
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 LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation of the retina.<
Headlight lenses
In cool or humid weather, condensation may
form on the interior of outside lamps. When the
light is switched on, the condensation will dis-
appear after a short time. The headlight lenses
do not need to be replaced.
At high humidities, e.g. water droplets may form
in the lights; have these checked by your BMW
center.

Giving and receiving assistance
220 The first aid pouch is located on the right-hand
side of the cargo area in a storage area.
Warning triangle*
The warning triangle is located in a holder in the
trunk lid. Press the tabs to take it out.
Jump-starting
If the car's own battery is flat, your BMW's
engine can be started by connecting two
jumper cables to another vehicle's battery. You
can also use the same method to help start
another vehicle. Only use jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Carefully adhere to the follow-
ing sequence, both to prevent damage to one or
both vehicles, and to guard against possible
personal injuries.<
Preparation
1.Check whether the battery of the other
vehicle has a voltage of 12 volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any consumers in both vehicles.
There must not be any contact between
the bodies of the two vehicles; otherwise,
there is a danger of shorting.<
Connecting jumper cables
Connect the jumper cables in the correct
order to prevent sparking at the battery,
which could cause injury.<
Your BMW has a jump-starting connection in
the engine compartment which acts as the bat-
tery's positive terminal, refer also to the Engine
compartment overview on page203. The cap is
marked with +.
1.Pull the cap of the BMW jump-starting con-
nection up to remove.
2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-aid terminal of the vehi-
cle providing assistance.
3.Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a starting-aid terminal of
the vehicle to be started.
4.Attach one terminal clamp of the minus/–
jumper cable to the negative terminal of the
battery or to an engine or body ground of
the assisting vehicle.

wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the above connecting sequence.
If necessary, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
Tow-starting, towing away
Observe the applicable laws and regula-
tions for tow-starting and towing vehi-
cles.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
It is stored with the onboard vehicle tool kit
underneath the floor mat in the cargo area, refer
to page213.
Use only the tow fitting provided with the
