Transporting children safelyYounger 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 rear-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
practice for securing child-restraint
systems in motor vehicles.
Child-restraint system securityAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
Information regarding this is located
near the buckle latch of each safety
belt. 530us104
To lock the belt Pull 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. To release the belt Release the buckle, remove the child-
restraint device and allow the belt
retractor to reel the belt completely in.

Indicator/Headlamp flasher
Upshifts or downshifts will only be
carried out at appropriate engine
speeds and road speeds. If the engine
speed is too high, for instance, the
downshift will not be executed. The
gear selected will appear briefly in the
instrument cluster followed by the
current gear.
If you are driving in the manual
mode and wish to accelerate
rapidly Ð to pass another vehicle, for
example Ð shift down manually or with
the kickdown function.<
You can only change from M/S to
selector lever positions "P", "R" and "N"
via the "D" position.
Electronic transmission control
module
If the indicator lamp comes on
or the message "TRANS.FAIL-
SAFE PROG" appears in the
Check Control
*, there is a fault in the
transmission system.
Bring the vehicle to a stop. Move the
transmission selector lever to "P". Set
the parking brake and switch the engine
off (ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission
performance has been restored. You
may continue to drive as usual. If the
indicator lamp does not go out, you can
place the selector lever in all positions.
However, the vehicle will now only drive
forward with limited gear selection.
If this happens, avoid extreme engine
loads and consult the nearest
BMW Sports Activity Vehicle center.
Do not work in the engine
compartment when a drive gear
(forward or reverse) is engaged. If you
do this, the vehicle could move.<

Variable Ride Height
*
Variable Ride Height on both axles
*
The warning lamp for the Vari-
able Ride Height comes on, or
the message "SELFLEVEL
SUSP.INACT" appears in the Check
Control: there is a malfunction in the
Variable Ride Height.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear),
consult the nearest BMW Sports
Activity Vehicle center. Drive with
appropriate caution in the meantime.
The vehicle has reduced ground clear-
ance or driving comfort is noticeably
reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW Sports Activity Vehicle center if
the warning lamp indicates a system
malfunction.
The conceptYour vehicle is equipped with Variable
Ride Height acting on both the front
and rear suspension. This system
combines automatic self-leveling,
which compensates for variations in
front-to-rear load-distribution patterns,
with a selection feature allowing drivers
to choose from among several ride-
height options.
You may choose from among the
following ride heights:
>Standard
The "standard" setting is intended for
most operating conditions, including
trailer towing
>Off-Road
Higher ride height for increased
ground clearance
>Access
Lowers vehicle for more convenient
cargo handling and easier passenger
ingress and exitsChanges in ride height are initiated
either manually, using the control
button (refer to page 96), or automati-
cally in response to specific speeds.
When the ride height is selected manu-
ally, the driver has the additional option
of revising the ride-height selection by
entering a new command during the
adjustment process.
When the vehicle is stationary, the
system executes ride-height changes in
both directions (up and down) when-
ever the doors are closed. The tailgate/
liftgate may be open. The system raises
the vehicle only when the engine is
running.
The system's automatic self-leveling
feature automatically compensates for
variations in the vehicle's load.
Frequent changes in ride height
initiated at short intervals can
overheat the compressor, causing the
system to briefly suspend active opera-
tion.<
