Starting engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.
To prevent the vehicle from rolling, always
select position P on the selector lever and
engage the parking brake before leaving
the vehicle with the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin to drive immedi-
ately at a moderate engine speed.
Your BMW is equipped with the conve-
nience starting feature. After pressing the
brake pedal, all you need to do is briefly
press the start/stop button. The system
responds by automatically engaging the
starter and allowing it to run until the engine
starts, after which it then disengages auto-
matically.
If the engine fails to start on the first
attempt, for instance, if it is very hot or cold:
Press the accelerator pedal halfway down
while engaging the starter.During a cold start at very low tempera-
tures, below + 57/– 156, at high altitudes
over 3,281 ft/1,000 m:
>Engage the starter for approx.
10 seconds the first time
>Press the accelerator pedal halfway
down while engaging the starter.
Refrain from starting the vehicle
repeatedly at brief intervals, and avoid
an excessive number of starting attempts if
the vehicle fails to start; repeated activation
of the starter over an extended period
would allow unburned or only partially
combusted fuel to enter the catalytic con-
verter, where it can cause overheating and
damage to the unit.<
If you have accidentally switched off
the engine while driving, it can be
restarted from a speed of approx. 3 mph/
5 km/h by pressing the button. It is not nec-
essary to press the brake pedal.<
Switching off engine
With the vehicle stationary, briefly press the
start/stop button. This also activates the
radio mode.
The transmission automatically shifts to
position P: interlock.
Transmission position N remains
engaged if you keep to the following
order:
1.With Comfort Access: insert the remote
control into the ignition lock
2.With the engine running, engage trans-
mission position N
3.Switch off the engine
4.Leave the remote control in the ignition
lock.
This function is useful in automatic car
washes, etc.
Position P is engaged automatically after
approx. 30 minutes or when you remove
the remote control from the ignition lock.
Remember to observe the Check Control
for status messages.<

Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
road surface. This phenomenon is referred
to as hydroplaning, and is characterized by
a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
Driving through water
Only drive through water with a maxi-
mum depth of 1 ft/30 cm, and then
only at walking speed at the most. Other-
wise, the vehicle's engine, the electrical
systems and the transmission may be dam-
aged.<
Safe braking
Your BMW is equipped with ABS as stan-
dard equipment. The best way to brake is
to apply maximum pressure to the brake
pedal during emergency: full brake applica-
tion. Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a minimum
of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Driving in wet conditions
While driving in wet conditions and in heavy
rain, it is a good idea to apply light pressure
to the brake pedal every few miles. Monitor
traffic conditions to ensure that this maneu-
ver does not endanger other road users.
The heat generated in this process helps
dry the pads and rotors to ensure that full
braking efficiency will then be available
when you need it.
Hills
To prevent overheating and reduced
efficiency of the brake system, drive
long or steep downhill gradients in the gear
in which the least braking is required. Otherwise, even light but consistent pedal
pressure can lead to high temperatures,
brake wear and possibly even brake fail-
ure.<
You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
page70. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never allow the vehicle to coast with
the transmission in Neutral – or with
the engine switched off – as there is no
engine braking when the transmission is in
Neutral, and no power-assist for brakes
and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion on brake rotors
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are
less frequent, there is an increased ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimal
pressure which must be exerted by the
pads during brake applications to clean the
rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a pul-
sating effect that even extended applica-
tion will fail to cure.
Mobile communications devices in
vehicle
BMW does not recommend using
mobile communications devices, e.g.
portable phones, in the interior of the vehi-
cle without a direct connection to an out-
side antenna. Otherwise the vehicle elec-
tronics and mobile communications device
can affect each other. In addition, it is not

Things to remember when driving
124 ensured that the radiation which results
during transmission will be discharged
from the vehicle interior.<
Cargo loading
To avoid loading the tires beyond
their approved carrying capacity,
never overload the vehicle. Overloading
can lead to overheating and increases the
rate at which damage develops inside the
tires. The ultimate result can assume the
form of a sudden air loss.<
Determine loading limit
1.Locate the following statement on your
vehicle's door pillar
*:
The combined weight of occu-
pants and cargo should never
exceed XXX lbs. or YYY kg, as other-
wise the vehicle may be damaged and
unstable driving conditions may
result.<
2.Determine the combined weight of the
driver and passenger that will be riding
in your vehicle
3.Subtract the combined weight of the
driver and passenger from XXX lbs. or
YYY kg
4.The resulting figure equals the available
amount of cargo and luggage load
capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150-lbs.
passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs.:
1,400 Ibs. minus 750 Ibs. = 650 Ibs.5.Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight should not exceed
the available cargo and luggage load
capacity calculated in step 4
6.If your vehicle will be towing a trailer,
part of the load from your trailer will be
transferred to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.
Load
The permitted load is the total of the weight
of occupants and cargo/luggage. The
greater the weight of occupants, the less
cargo/luggage can be transported.
Stowing cargo
>Load heavy cargo as far forward and as
low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners
>For very heavy cargo when the rear seat
is not occupied, secure each safety belt
in the opposite buckle.
