Starting the engine
Do not run the engine in closed rooms,
otherwise the inhaling of toxic exhaust
gases can cause unconsciousness 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, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the hand-
brake to prevent the car from moving.<
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 immediately at a moder-
ate engine speed.
Do not depress either the brake or the
clutch until you are ready to start the
engine. The engine is started immediately
when you briefly touch the start/stop button
and depress the brake if the car has automatic
transmission, or the clutch if the car has manual
transmission.<
Manual transmission
1.Apply the handbrake.
2.Depress the clutch and shift to idle position.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission
1.Depress the brake.
2.Move the selector lever to position P.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Sequential manual gearbox SMG*
1.Depress the brake.
2.Engage selector lever position N and make
sure that this position is displayed in the
instrument cluster.
3.Start the engine.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
If the engine does not start, depress the
brake and push the selector lever to the
right, then engage position N. Observe the dis-
play in the instrument cluster while doing so.<
Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. + 57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking on a downhill incline, apply the

Driving
44 handbrake, otherwise the vehicle could roll
away.<
Manual transmission
1.Apply the handbrake.
2.With the car at a standstill, briefly press the
start/stop button.
3.Shift into first gear or reverse.
Automatic transmission
1.With the car at a standstill, move the selec-
tor lever to position P.
2.Briefly press the start/stop button.
3.Apply the handbrake.
Sequential manual gearbox SMG
1.Apply the handbrake.
2.Engage a drive position.
3.Briefly press the start/stop button.
If the engine is switched off while N is engaged,
this will be signaled visually and acoustically.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off an acoustic signal sounds in
addition. The handbrake is still applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
In exceptional cases, if the handbrake has
to be used to slow or stop the car, do not
pull the lever up too hard. In doing so, continu-
ously press the button of the handbrake lever.
Otherwise, too violent an application of the
handbrake can overbrake the rear axle and
cause the rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission
When shifting into 5th or 6th gear, press
the gearshift lever to the right. Otherwise
the engine could be damaged if you inadvert-
ently shift into 3rd or 4th gear.<

Reverse gear
Select only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.
Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated transmission in which operation of
the clutch and gearshifts are performed by an
electro-hydraulic system.
SMG is operated via the selector lever in the
center console and two shift paddles on the
steering wheel.
It offers you the following functions:
>Choice of manual or automatic operation:
sequential mode or Drive mode
>Choice of two driving programs: Normal or
Sport, refer to Dynamic Driving Control,
page46
>Automatic downshifting and prevention of
misshifting in sequential mode as well
>Acceleration assistant, refer to page47
Selector lever positions
The current selector lever position can be seen
on the center console.
>R: Reverse gear
>N: Neutral, idle
>One-touch functions for sequential mode:
+: manual upshifting
–: manual downshifting>D: Drive mode or sequential mode
N is automatically selected when the
driver's door is opened while the engine is
running, as long as the pedals, shift paddles and
selector lever are not operated.
This is indicated by an acoustic signal and a
flashing N in the instrument cluster.<
Gear indicator
R N 1 to 6
The gear currently engaged is displayed, pre-
ceded by a D in Drive mode.
This indicator is the only way you can
confirm whether or not the desired selec-
tor lever position is engaged.<
Shiftlock
Before moving the lever away from N with the
vehicle stationary, first depress the brake; oth-
erwise the desired gearshift will not be carried
out.
R Reverse
Select only when the vehicle is stationary.
Gear-change mode
The gears can be changed in two different
ways.
>Sequential mode
Gears are shifted by means of the shift pad-
dles or the selector lever.
>D Drive mode
All forward gears are shifted automatically.
You can switch from one mode to the other by
pressing the selector lever towards the right in
the direction of D.

Things to remember when driving

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Attempt to vary both engine and vehicle
speeds, but refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100mphor 160km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
After 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Sequential manual gearbox SMG
Do not use the acceleration assistant during the
break-in period, page47.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx. 300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle.<
If special circumstances make it absolutely nec-
essary to drive with the luggage compartment
lid open:
1.Close all windows and the glass sunroof.
2.Increase the air flow rate of the air condi-
tioner or automatic climate control consid-
erably, refer to page81 or84.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage.<
Mobile phone in the vehicle
BMW discourages the use of mobile
communications devices, e.g. mobile
phones, inside the vehicle without a direct con-

nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
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 sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page115.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Sequential manual gearbox SMG
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; apply the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Also use the drive-off assistant, refer to
page71.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver 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 the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<

Giving and receiving assistance
134 gaged and the car is not steerable. Jump start-
ing, refer to page132.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Switch on the hazard warning flashers, depend-
ing on local regulations.
Manual transmission
Gearshift lever in idle position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page47.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Sequential manual gearbox SMG
With the ignition switched on, engage selector
lever position N, and then switch the ignition
back off.
Towing with a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
Towing with a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
Towing with a tow truck
323i*, 325i, 330i
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
325xi, 330xi
Do not tow a BMW with xDrive with just
the front or rear axle raised, otherwise the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
If the electrical system fails, do not
attempt to tow-start or tow away the car.
The electric steering wheel lock cannot be dis-

engaged and the car is not steerable. Jump
starting, refer to page132.<
Do not tow-start vehicles with an auto-
matic transmission. Only tow-start vehi-
cles with a catalytic converter with the engine
cold. It is better to jump start the engine, refer to
page132.<
1.Switch on the hazard warning flashers,
comply with local regulations.
2.Switch on the ignition, refer to page42.
3.Shift into 3rd gear. Vehicles with SMG, see
below.
4.Have the vehicle tow-started with the clutch
completely depressed and slowly release
the clutch. After the engine starts, immedi-
ately depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
Vehicles with sequential manual gearbox SMG:
1.Have the vehicle tow-started with the selec-
tor lever in position N.
2.Select sequential mode. The correct gear is
automatically engaged.
325xi, 330xi: do not activate Hill Descent
Control HDC when the vehicle is being
tow-started, page69.<
