not fastened, if objects are placed on the front
passenger seat, or if driver or front passenger
unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stressed in an accident: have the belt sys-
tem, including any belt tensioners or child-
restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly.<
Mirrors
Exterior mirrors
The front passenger's mirror is more con-
vex than the driver's mirror. The objects
seen in the mirror are closer than they appear.
Do not gauge your distance from traffic behind
you on the basis of what you see in the mirror;
otherwise there is an increased risk of an acci-
dent.<

Folding mirrors in and out*
At driving speeds up to approx. 12 mph/
20 km/h, you can fold the mirrors in and out by

that were folded in by hand back out into their
correct positions. Mirrors that were folded in are
folded out automatically at a speed of approx.
25 mph/40 km/h.
Before entering an automatic car wash,
fold in the exterior mirrors by hand or with
button3, to prevent them from being damaged
due to the width of the vehicle.<

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example.<
The rear center seat is not suitable for installing
child-restraint systems for all age groups,
approved for the age group in question.
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child-restraint systems
appropriate for their age, weight and size. Oth-
erwise there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restraint system that is
appropriate for their age, size and weight.
Exception for front passenger seat
Should it be necessary to use a child-
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, even
with a child-restraint system.<
For more information on automatic deactivation
of the front passenger airbags refer to page94.
Installing child-restraint
systems
Observe the child-restraint system man-
ufacturer's instructions when selecting,
installing and using child-restraint systems.
Otherwise the protective effect may be dimin-
ished. to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly
or improperly installed child-restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the front passenger seat
After installing a child-restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated, otherwise there is an
increased risk of injury if the airbags deploy.<
Backrest width*
The backrest width of the front passen-
ger's seat must be at its widest possible
setting. Do not change the setting after install-
ing the child seat. Otherwise the child seat's
stability on the front passenger's seat is lim-
ited.<
1.Adjust the backrest width to its widest set-
ting, refer to page45.
2.Install the child seat.
Child seat security
The rear safety belts and the front passenger's
safety belt can be prevented from being pulled
out in order to fasten child-restraint systems.

LATCH child-restraint fixing
system
LATCH: Lower Anchors and Tethers for CHil-
dren.
To install and use the LATCH child
restraint system, follow the operating and
safety instructions provided by the manufac-
turer of the system, otherwise the protective
function of the seat may be compromised.<
Before installing the child seat, pull the belt out
of the area for the child-restraint fixing system.
Ensure that both lower LATCH anchors
are correctly engaged and that the child
restraint system is resting firmly against the
backrest, otherwise the protective function of
the seat may be compromised.<
Rear seats with through-loading
system
The anchor points for the lower LATCH
anchors are located behind the labeled protec-
tive caps.
Rear seats without through-loading
system
The anchor points for the lower LATCH
anchors are located at the positions indicated
by arrows, in the gap between the seat and the
backrest.
Child-restraint system with tether
strap

child-restraint systems only, otherwise
the anchors could be damaged.<

Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation 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 forcefully apply
the parking brake to prevent the car from mov-
ing.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
