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 page 73.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.

certain functions are active:

Starting the engine
You can start the engine or switch on the igni-

It is not necessary to insert a remote control into
the ignition swit ch, refer to page 50.
Switching off the engine in cars with
automatic transmission
The engine can only be switched off when the
selector lever is in position P, refer to page 52.
To switch the engine off when the selector lever
is in position N, the re mote control must be in

local radio waves. If this happens, open or close
the vehicle via the buttons on the remote con-
trol or using the integr ated 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 co ntrol 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.

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 page201.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 210 7/100 6 and approx. 300 7/
150 6.
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
page 188.
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. <

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 vehicle emissions are raised. 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, espe cially 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 ca p 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 fa cilitate the corresponding
services.
