Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this below.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. There is a malfunction
of the alternator drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

An alarm sounds at the same
time. Stop vehicle immediately
and switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct: please contact
the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.
For additional information: refer to
page 87
Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 114 and 129.

SERVICE ENGINE SOON

●

If the indicator lamp comes on
either continuously or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.

Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.

●

There is a fault in the electronic
engine-management system.
You can continue to drive with reduced
engine output or engine speed. Please
have the system inspected at your
BMW center.
Add coolant
Coolant level too low, top up as
soon as possible.

Close the gas cap carefully after
refueling until a click is heard.
While closing, be sure not to squeeze
the strap which is fastened to the cap.
A loose or missing cap will activate the
CHECK GAS CAP* lamp.<
Fuel tank capacity>Approx. 16.6 gal./63 liters, of which
>approx. 2.1 gal./8 liters are reserve
capacity.
Do not drive to the last drop of
fuel. This can prevent the engine
from operating properly and result in
damage.<
Fuel specificationsThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Never use leaded fuel, as it would
cause permanent and irreversible
damage to the oxygen sensor and the
catalytic converter.<
Tire inflation pressureChecking tire pressuresTire pressures in psi/kilopascal are
shown on the driver's door post and are
visible when the door is open.
Only check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
In the following tire inflation pressure
table, all pressures are specified in the
standard units of pressure, psi and kilo-
pascal, and apply to cold tires, i.e. tires
at ambient temperature.
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor so
that it can monitor the tire inflation
pressure, refer to page 87.

Indicator lamp
The gearbox indicator lamp in
the instrument cluster goes out
after the engine is started.
>If it does not go out, or if it lights up
during driving, a malfunction has
occurred. The available functions
may be limited under certain circum-
stances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the opti-
mum shifting point shortly before the
maximum engine speed is reached.
1. When the maximum engine speed is
approached, yellow indicator fields –
shift lights – in the tachometer light
up consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.
Tire replacement, snow chainsFollowing a tire or wheel change and
after mounting or removing snow
chains, the slip recognition of the
SMG Drivelogic must become familiar
with the changed condition.
Reinitialize the system afterwards:
1. Move the selector lever into
position N on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
two seconds.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx.
2 gallons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx. 16.6 gal./
63 liters.
If the tilt of the vehicle varies – when
you are driving in mountainous areas,
for example – the needle may fluctuate
slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on while operating
the vehicle: the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
To check the coolant level, refer to
page 128.

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a '–' in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayWhen the ignition key is in position 2,
the following information and/or condi-
tions are indicated using symbols until
the conditions have been corrected.
1Inspect the low-beam and high-beam
headlamps, as well as the parking
lamps
2Door open
3Luggage compartment lid open
4Check brake and tail lamps
When you open the driver's door after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.

123 In the engine compartment
HoodTo releasePull the lever located under the left-
hand side of the instrument panel.
Do not attempt to service your
vehicle if you do not have the
required technical background. Failure
to work in an informed, professional
manner when servicing components
and materials constitutes a safety haz-
ard for vehicle occupants and other
road users. If you are not familiar with
the guidelines, BMW recommends that
you have the operations performed by
your BMW center.<
To openPull the release handle and open the
hood.
It is not possible to drive off using
SMG Drivelogic when the hood is
open.<
To closePull the hood downwards and allow the
hood to fall from a minimum height of
1 ft/30 cm so that it audibly engages.
Check for proper locking by pulling on
the hood at the left and right above the
headlamps.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, following the same
safety precautions used in all closing
procedures.
If you notice while driving that the hood
is not completely closed, stop immedi-
ately and close it securely.<
