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 in the follow-
ing section.
 
Red: stop immediately
 
Battery charge current
 
●
 
The battery is no longer being 
charged. Indicates a defective 
alternator drive belt or a problem with 
the alternator's charge circuit. 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
 
●
 
Stop the vehicle immediately 
and switch off the engine. 
Check the engine oil level; top off as 
required. If the oil level is correct: 
please contact the nearest BMW cen-
ter.
Do not continue driving, as the 
engine could sustain serious dam-
age from inadequate lubrication.
 
<
 
Tire Pressure Monitor (TPM)/Flat 
Tire Monitor
 
●
 
In addition, an acoustic signal is 
sounded: a tire failure has occurred. 
Reduce vehicle speed immediately and 
stop the vehicle. Avoid hard brake 
applications. As you steer the vehicle, 
use caution to avoid overcorrecting.
For additional information: refer to 
pages 92, 93
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 124 and 139.
Parking brake warning lamp for 
Canadian models.
 
Red: an important reminder
 
Brake warning lamp
Comes on when the parking 
brake is engaged – an additional 
acoustic signal sounds when you start 
off.

Canadian models.
Lock backrest/Fasten safety 
belts 
 
●
 
Comes on together with an 
acoustic signal until the safety belts are 
fastened. Flashes if the backrest is not 
locked.

Please have the system 
inspected at your BMW center.

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 gallons/63 liters.
Certain operating conditions, such as 
those encountered in mountainous 
areas, may cause the needle to fluctu-
ate 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.RedWhen you switch on the ignition, the 
warning lamp comes on briefly as an 
operation check.
If the lamp comes on during normal 
vehicle operation: the engine has over-
heated. Shut off the engine immediately 
and allow it to cool down.
To check coolant level, refer to 
page 138.
Between the blue and red zonesNormal operating range. The needle 
may rise as far as the edge of the red 
sector during normal operation.

Tire Pressure Monitor (TPM)*The conceptTPM monitors the tire pressures at all 
four tires even while the vehicle is mov-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in 
one or more tires.
This indicator lamp in the instru-
ment cluster informs you when 
the tire pressure deviates from 
the target values.
Initializing the systemInitializing is necessary to familiarize the 
system with the correct inflation pres-
sures. 
Repeat this process after tire replace-
ment, tire rotation or any changes in tire 
inflation pressure.
1. Check the tire inflation pressures in 
all the tires, comparing them with the 
inflation pressure chart on page 25, 
and adjust them if necessary
2. Turn the ignition key to position 2, do 
not start the engine
3. Press the button long enough for the 
yellow indicator lamp in the instru-
ment cluster to light up for a few sec-
onds
4. After a few minutes' driving time, 
TPM adopts the current inflation 
pressures in the tires as the refer-
ence values to be monitored.In the event of loss in inflation 
pressureIf the inflation pressure has dropped 
significantly over a long period of time, 
which is normal for any tire, the yellow 
indicator lamp will come on.
This alerts you to have the tires inflated 
to the specified pressures as soon as 
possible.
If you are prompted to check the 
tire pressure shortly after a cor-
rection has been made, this indicates 
that the corrected values were not 
valid. Please check the inflation pres-
sure again and make corrections 
according to the inflation pressure 
table. Then reinitialize the system.
on. This visual alert is accompanied by 
an acoustic warning signal.

Coolant
Do not add coolant to the cooling 
system when the engine is hot. If 
you attempt to do so, escaping coolant 
can cause burns.
Antifreeze and anti-corrosion agents 
are hazardous to health. You should 
always store them in their closed origi-
nal containers and in a location which is 
out of reach of children. Antifreeze and 
anti-corrosion agents are inflammable. 
For this reason, do not spill them on hot 
engine parts. They could ignite and 
cause serious burns. Comply with the 
instructions on the containers.<
Checking the coolant level and 
adding coolantCheck the coolant level when the 
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank 
by turning it slightly counterclock-
wise to allow accumulated pressure 
to escape, then open
2. The coolant level is correct when the 
upper end of the red float rod – see 
arrow – is at least even with the 
upper edge of the filler neck, but no 
more than 3/4 in / 2 cm above – that 
is, up to the second mark on the float 
rod
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until 
the correct level is reached – do not 
overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<

157 Giving and receiving assistance
Jump-startingWhen your battery is discharged you 
can use two jumper cables to start your 
vehicle with power from the battery in a 
second vehicle. You can also use the 
same method to help start another 
vehicle. Only use jumper cables with 
fully insulated handles on the terminal 
clamps.
Do not touch high-voltage wiring 
and cables on a running engine. 
Contact with components carrying high 
voltage can be harmful or fatal. Care-
fully observe the following instructions 
to avoid personal injury and/or damage 
to one or both vehicles.<
1. The battery in the support vehicle 
must also be rated at 12 volts. This 
information is provided on the battery 
label
2. Stop the engine of the support vehi-
cle and switch off all electrical com-
ponents in both vehicles – except for 
the hazard warning flashers of the 
support vehicle
3. Make absolutely certain that there is 
no contact between the bodywork of 
the two vehicles – short circuit haz-
ard
4. The auxiliary jump-starting terminal 
located in your BMW's engine com-
partment acts as the positive battery 
terminal. The cover of this auxiliary 
terminal is marked with a + sign. 
Remove by pulling the tab – see 
arrow 1.
Start by connecting the jumper cable 
from the positive terminal of the dis-
charged battery to the positive termi-
nal of the support battery
5. Then connect the negative terminals 
with the other jumper cable. First 
connect one end to the negative bat-
tery terminal or to a suitable ground 
on the support vehicle. Then connect 
the other end to the negative battery 
terminal or a suitable ground on the 
vehicle being started.
Your BMW is equipped with a special 
nut for this purpose – see arrow 2
Always adhere to this sequence 
when connecting jumper cables; 
failure to observe this procedure can 
lead to sparks at the battery terminals 
and pose an injury hazard.<
6. Start the engine of the support vehi-
cle and let it run for several minutes 
at a slightly elevated engine idle 
speed
7. Start the engine of the other vehicle 
as usual. If the first start attempt is 
not successful, wait a few minutes 
before another attempt in order to 
allow the discharged battery to 
recharge
8. Before disconnecting the jumper 
cables, let the engines run for a few 
minutes
9. Then disconnect the jumper cables 
in reverse sequence.
Depending on the cause of the fault, 
have the battery checked and 
recharged by your BMW center.
