Transporting children safelyThis important precaution is intended to
maximize the distance between the
airbag and the child. Older children
should be tightly secured with a safety
belt, after they have outgrown a booster
seat that is appropriate for their age,
height and weight.
Younger children should be secured in
an appropriate forward-facing child-
restraint system that has first been
properly secured with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat. We strongly urge you to carefully
read and comply with the instructions
for installation and use provided by the
child restraint's manufacturer when-
ever you use such a device.
Be sure that all occupants (of all ages)
remain properly and securely restrained
at all times.<
All rear seating positions in your vehicle
meet the recommendations of SAE
J1819, an industry-recommended prac-
tice for securing child-restraint systems
in motor vehicles.
Child-restraint installationAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems. A label with the
appropriate instructions is located in
the immediate vicinity of the buckle
latch of each safety belt.Lock the safety beltExtract the entire length of the belt from
the belt retractor. Allow the reel to
retract the belt somewhat and engage
the buckle, then tighten the belt against
the child-restraint system. The retrac-
tion mechanism is now locked.Unlock the safety beltRelease the buckle, remove the child-
restraint device and allow the belt
retractor to reel the belt completely in.365us146

LATCH: Lower Anchor and Tethers for
CHildren.
Snap the rear center lap belt into the
buckle with the word CENTER and then
pull the belt away from the area where
the child restraint will be mounted.

Parking brake Manual transmission The parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates on the rear
wheels.To engageThe lever engages automatically when
it is pulled up, and the "PARK BRAKE"
(in Canada "P") indicator lamp comes
on in the instrument cluster in ignition
key position 2. Refer to page 17. To releasePull up slightly on the lever, press the
button and lower the lever.390de714
If, in exceptional circumstances, it
should be necessary to engage
the parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up to apply mod-
erate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle.
The brake lamps do not come on when
the parking brake is applied. Always
engage the parking brake when parking
on hills and inclined surfaces, as even
first gear or reverse may not provide
adequate resistance to rolling.<
You can help prevent corrosion and
maintain balanced braking by periodi-
cally pulling up the parking brake lever
gently while coasting to a stop at a
traffic light. Always check traffic condi-
tions first to avoid posing a hazard to
yourself or other road users.
When shifting gears, always depress
the clutch pedal all the way down, then
move the gearshift lever until it engages
securely in the desired gear.
You will also need to depress the clutch
when starting the engine, as an auto-
matic lockout prevents the starter from
operating when the clutch is engaged.
When the vehicle lighting is switched
on, the shift pattern is illuminated on
the gearshift lever.
When shifting gears in the 5th/
6th-gear plane, be sure to press
the gearshift lever to the right in order
to prevent inadvertent selection of a
gear in the 3rd/4th-gear plane.<39mde017

vehicle and switch off the engine
immediately. Refer to pages 16, 115>"CHECK BRAKE FLUID"
The level has dropped nearly to the
minimum. Top up the brake fluid at
the earliest opportunity. Refer to
page 118. Have the source of the
brake fluid loss diagnosed and cor-
rected at your BMW center
>"TIRE DEFECT"

Reduce vehicle speed immediately
and stop the vehicle. Avoid hard
brake applications. Do not oversteer.

Fold the rear backrests downReach into the recess and pull forward
(arrow 1).
When you close the backrest, be sure
that the catch engages securely.
The red slide (arrow 2) must retract
completely.394de745
The central belt has an additional small
buckle.
>If you connect the two belt sections,
you can use the central belt as any
normal 3-point belt
>It is easier to fold the rear-seat back-
rest up and down if you disconnect
the belt (arrow).394de746
With a master key you can lock each
backrest in the rear seat.
This also prevents access to the lug-
gage compartment from the interior of
the vehicle if you turn over only your
door and ignition key 3 (refer to
page 26). This is convenient for valet
parking, for instance.394de747

Cargo loading Roof-mounted luggage rack
*
Always position and secure the
load correctly. If you do not, it can
endanger the passengers during
braking or evasive maneuvers.
Never exceed either the approved
gross vehicle weight or the approved
loads for either of the axles (refer to
page 142), as overloading the vehicle
beyond the legally approved levels can
severely compromise its operating
safety.
Do not carry hard or heavy objects
unsecured in the passenger compart-
ment. If you do so, they may be pro-
jected through the air during braking
and evasive maneuvers, thus endan-
gering vehicle occupants.<
A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the cover (arrow), please use
the tool provided with the roof-rack
system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
have a major effect on the vehicle's
handling and steering response.394de757
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the axle weights when
loading the rack. These weights are
listed under "Technical Data" ,
page 142.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Be sure that adequate
clearance is maintained for raising the
sliding/tilt sunroof.
Secure the roof luggage correctly
and securely to prevent it from
shifting or being lost during driving
(danger to following traffic).<
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.
