To unlockPull the lever located under the left-
hand side of the instrument panel.
Do not attempt to service your
vehicle if you do not have the
required technical background. Failure
to work in an informed, professional
manner when servicing components
and materials constitutes a safety
hazard for vehicle occupants and other
road users. If you are not familiar with
the guidelines, please have the opera-
tions performed by your BMW center.<390de759
To openPull the release handle and open the
hood. 390de760
To closeAllow the hood to fall from a height of
about 4 in (10 cm) so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, observing the same
precautions recommended for all
closing procedures.
If you notice that the hood is not com-
pletely closed while driving, stop imme-
diately and close it securely.<390de761

Lamps and bulbs Xenon lamps

The service life of these bulbs is very
long and the probability of a failure is
very low, provided that they are not
switched on and off an unusual number
of times. If one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the fog lamps, provided traffic laws in
your area do not prohibit this.
Never attempt to perform bulb
changes or any other service oper-
ations on the xenon lamps. Always have
them serviced by professional techni-
cians. The extremely high voltages at
which these lamps operate constitute a
potentially lethal safety hazard.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (this causes scratches). Never
use abrasives or strong solvents to
clean the covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with
ample water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<

Battery FusesCharging the battery Recharge the battery only with the
engine off, using the auxiliary terminals
provided in the engine compartment
(for information on these terminals refer
to "Jump-starting" on page 133).
Avoid environmental pollution
when disposing of old batteries.<
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery to prevent it from tilting
during transport.<
In the glove compartmentOpen the glove compartment and turn
the two white quick-release fasteners
to the left.390de085
In the luggage compartmentUse the handle to pull down the trim on
the right wall.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. Installing the wrong fuse could
cause a fire in the vehicle resulting from
a circuit overload.<394de678

Towing the vehicleTow fittingThe screw-in tow fitting is stored in the
onboard tool kit; be sure that it remains
in the vehicle at all times. This fitting
is designed for installation in the tow
sockets located at the front and rear of
the vehicle, and is intended for towing
on proper road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Always observe all applicable towing
laws and regulations.Access to tow sockets Front:
Apply pressure to the arrow symbol on
the cover; remove the cover.390de087
Rear:
Apply pressure to the arrow symbol on
the cover; remove the cover.
Screw the tow fitting in until it bot-
toms firmly. Failure to screw the
fitting in securely can lead to thread
damage.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
arms, or any other part of the vehicle
suspension, as severe damage to these
components will occur, leading to pos-
sible accidents.<
Use only a nylon towing strap to tow
the vehicle. The inherent resilience of
this material helps protect both vehicles
from sudden jerking movements.394de088
Keep the vehicles in line and avoid
towing at an offset angle. Ensure
that the tow rope connecting the two
vehicles is tight, with no slack, before
starting off.<
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingIt is better to start the vehicle's engine
by jump-starting. For instructions on
jump-starting, refer to page 133.
Never attempt to use your vehicle to
push another vehicle, as damage to the
energy-absorbing bumpers could
result.
