Comfort Access*
Comfort Access enables you to enter your vehi-
cle without needing to hold the remote control
in your hand. All you need to do is wear the
remote control close to your body, e.g. in your
jacket pocket. The vehicle detects the corre-
sponding remote control within the immediate
vicinity or in the passenger compartment.
Comfort Access supports the following func-
tions:
>Unlocking/locking the vehicle
>Unlocking the trunk lid separately
>Engine starting
>Convenient closing

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot.
Check coolant level, refer to page117.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a warn-
ing lamp comes on in the instrument cluster.
Fuel gauge
Fuel tank capacity: approx. 14 US gallons/
53 liters.
You can find information on refueling on
page104.
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.
Fuel display 135i: in speedometer.
Reserve
Once the fuel level has fallen to the reserve
zone, the indicator lamp lights up briefly and the
cruising range for the remaining amount of fuel
is displayed. The indicator lamp stays on per-
manently when the remaining range is less than
approx. 30 miles/50 km.
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.<

tems monitored. Such a Check Control mes-
sage includes indicator or warning lamps in the
instrument cluster and, in some circumstances,
an acoustic signal.
Indicator and warning lamps can light up in a
variety of combinations and colors.
Several of the lamps are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.

1.Start the engine immediately before pulling
away, but do not drive off yet.
2.Lightly push button 1 in the turn indicator
lever up or down repeatedly until the corre-
sponding symbol appears in the display
accompanied by the word "RESET".
3.Press button 2 to confirm your choice of the
Flat Tire Monitor.
4.Press button 2 for approx. 5 seconds, until
the reading shown below is displayed:
5.Start driving.
Initialization is completed while the car is on
the move, without any feedback.
Indication of a flat tire
The warning lamps come on in yellow
and red. In addition, a signal sounds.
There is a flat tire or substantial loss
of tire pressure.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the car is not equipped with run-flat
tires, refer to page112, the standard
equipment by design, do not continue driv-ing. A severe accident could result if you
continue driving after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the distance
for which you can continue driving on the
basis of the following guidelines:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo area full, or 4 persons
without luggage:
approx. 90 miles/150 km
>With a full load:
4 persons, cargo area full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h; otherwise,
there is a risk of an accident. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over as soon as possible at a
suitable location. Otherwise, parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.<
Tire Pressure Monitor TPM*
The concept
RDC monitors the tire inflation pressure in the
four mounted tires during a trip. The system
notifies you if there is a significant loss of pres-
sure in one or more tires.

Lamps
76
Adaptive light control*
The concept
Adaptive light control is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves at speeds up to 40 mph/70 km/h,
e.g. on mountainous roads or when turning, an
additional, corner-illuminating lamp is switched
on that lights up the inside area of the curve.
Activating adaptive light control
With the ignition switched on, turn the light
switch to position 3, refer to page74.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
Standstill function
*: to avoid blinding oncoming
traffic, the adaptive light control directs light
towards the front passenger side when the
vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are active and switched on on
both sides.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive light control is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/roadside parking
lamps*
1High beams
2Headlamp flasher
3Roadside parking lamps

Roadside parking lamps, left or right*
There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point for approx.
1second, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the
engine.<
Switching off
Press the lever in the opposite direction to the
pressure point, arrow 3.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handles this task for you and
gives you the benefit of the best possible view.

Possible displays
1Oil level OK
2Oil level is being checked.
This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add engine oil as soon as possible, but no
more than 1 US quart/1 liter, refer also to
Adding engine oil on page116.
4Oil level is too high.
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
5The oil level sensor is defective.
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page118. Have the system checked as
soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil until
the following warning lamp lights up in the
instrument cluster or the oil level display reads
"+1l".
Add oil within the next 125 miles/200 km;
otherwise, the engine could be dam-
aged.<
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.
Specified engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW routinely approves specific
oils after testing them extensively.
Do not use oil additives as these may
cause engine damage.<
