Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a
variety of combinations and colors.
Some lamps are checked for proper functioning
and thus come on briefly when the engine is
started or the ignition is switched on.
Explanatory text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
You can call up more information, e.g., on the
cause of a malfunction and on how to respond,
via Check Control, refer to page73.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.
Indicator lamps without text messages
The following indicator lamps notify you that
certain functions are active:

transmission into a car wash
1.Insert the remote control into the ignition
switch.
2.Depress the brake.
3.Move the selector lever to position N.
4.Switch off the engine.

Malfunction
Comfort Access may malfunction due to local
radio waves. If this happens, open or close the
vehicle via the buttons on the remote control or
using the integrated key. To start the engine
afterward, insert the remote control into the
ignition switch.
Warning lamps
The warning lamp in the instrument
cluster lights up when you attempt to
start the engine: the engine cannot
be started. The remote control is not inside the
vehicle or is malfunctioning. Take the remote
control with you inside the vehicle or have it
checked. If necessary, insert another remote
control into the ignition switch.
The warning lamp in the instrument
cluster lights up while the engine is
running: the remote control is no
longer inside the vehicle. After the engine is
switched off, the engine can only be restarted
within approx. 10 seconds.
The indicator lamp in the instrument
cluster comes on and a message
appears on the Control Display:
replace the battery in the remote control.
Replacing the battery
The remote control for Comfort Access con-
tains a battery that will need to be replaced from
time to time.
1.Take the integrated key out of the remote
control, refer to page28.
2.Remove the cover.
3.Insert the new battery with the plus side fac-
ing up.
4.Press the cover on to close.
Take the old battery to a battery collec-
tion point or to your BMW center.<
Windows

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control
Display.
Check coolant level, refer to page204.
Engine oil temperature*
When the engine is at normal operating
temperature, the engine oil temperature is
between approx. 2107/1006 and approx.
3007/1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14.5 US gallons/
55 liters.
You can find information on refueling
on page192.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control
Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<

Under the hood
204 >"Measurement inactive. Have this
checked."
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page69. Have the system checked as
soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil until
a corresponding message is shown on the
Control Display.
Add oil within the next 125 miles/200 km;
otherwise, the engine damage could
occur.<
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 types
Do not use oil additives as these may
cause engine damage.<
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
important to follow the instructions on the con-
tainers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the expansion tank cap counterclock-
wise slightly to allow any accumulated pres-
sure to escape, then continue turning
to open.

Socket for Onboard
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located under a cover on the left
on the driver's side.
Exhaust emission values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the car
checked as soon as possible.
Canadian models display this warn-
ing 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. If the gas cap is then tightened, the
warning lamp should go out within a few days.
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.

Giving and receiving assistance
220 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.
Your BMW has a special nut as body ground
or negative pole.
5.Attach the second terminal clamp of the
minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
Starting the engine
1.Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.
2.Start the engine on the other vehicle in the
usual way.
If the first start attempt is not successful,
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
vehicles.<
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 in the onboard vehicle tool kit under-
neath the floor panel in the cargo area, refer
to page212.
Use only the towing eyelet supplied with
the vehicle and screw it in firmly until it
stops. Use the tow fitting for towing on paved
roads only. Avoid lateral loading of the tow fit-
ting, e.g., do not lift the vehicle by the tow fitting.
Otherwise, the tow fitting and the vehicle could
be damaged.<
