Things to remember when driving
86 safely exceed the available cargo and lug-
gage load capacity calculated in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permitted load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>To protect passengers, use the partition
net, refer to page78.
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
rear seat backrests.
>Cover sharp edges and corners.
>Do not stack cargo higher than the upper
edge of the backrests.
>Items that could bump against the rear win-
dow while driving must be adequately cov-
ered.>For very heavy cargo when the rear seat is
not occupied, secure the safety belt on
each side in the buckle on the opposite
side.
Securing cargo
>Use the luggage net* o r d r a w s t r a p s t o h o l d
down small and lightweight luggage and
cargo, refer to page78.
>For larger and heavier pieces, heavy-duty
cargo straps
* are available from your BMW
Sports Activity Vehicle Center. These
heavy-duty cargo straps are secured to
lashing eyes mounted in the cargo area,
refer to page78.
Read the information provided with the
heavy-duty cargo straps.
Always position and secure cargo as
described above. If you do not, it can
endanger the passengers during braking or
evasive maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle weights,
refer to page130, as excessive loads can pose
a safety hazard and may also put you in violation
of road safety laws.
You should never transport unsecured heavy or
hard objects in the passenger compartment, as
they could be thrown around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuvers.
Use only the lashing eyes, refer to page78, to
fasten the heavy-duty cargo straps. Do not use
the upper attachment points for top tether, refer
to page36, to secure cargo; this can damage
them.<

Roof-mounted luggage rack*
A special rack system is available as an optional
accessory for your BMW. Please familiarize
yourself with the information contained in the
installation instructions.
Loading luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
its handling and steering response. 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 specifications can be found under
Weights on page130.
The roof load must be evenly distributed and
must not extend outward beyond the limits of
the loading surface. Always stow the heaviest
pieces on the bottom. Be sure that adequate
clearance is maintained for raising the glass
sunroof and that objects do not project into the
opening path of the liftgate.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
while you drive.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
Driving on poor roads
Y our B MW is a t home on all pa ve d a nd unpa ved
roads. It combines all-wheel drive with the
advantages of a normal passenger car.
Do not drive off-road, as otherwise the
vehicle may be damaged.<
When you are driving on poor roads, there are a
few points which you should strictly observe –
for your own safety and that of your passengers,
as well as to protect the vehicle:
>Familiarize yourself with the vehicle before
you begin driving. Do not take risks with the
vehicle under any circumstances.>Always adapt your driving speed to the road
conditions. The more steep and uneven the
roadway is, the lower the speed should be.
>You can operate your vehicle on uphill and
downhill gradients with a maximum slope
of 50 %. If you wish to drive on uphill and
downhill grades of this nature, make sure
beforehand that the engine oil and coolant
levels are near the MAX mark, refer to
pages103 and105.
>When descending very steep hills, use
HDC Hill Descent Control, refer to page52.
It is possible to start off on inclines of up
to 32 %.
The permitted side tilt is 32 %.
>While driving, watch carefully for obstacles
such as rocks or holes. Try to avoid these
obstacles whenever possible.
>Avoid having the body make contact with
the ground, e.g. on the crests of hills and
bumpy roads. The ground clearance of the
vehicle is a maximum of approx. 8.0 in/
20 cm. Please be aware that the ground
clearance can vary depending on the load
and operating conditions of the vehicle.
>Do not drive in water that is deeper than
20 in/50 cm. If you must drive through water
up to that depth, drive at a walking speed
and do not stop.
After leaving the water, press on the foot-
brake gently several times while driving at a
low speed. The brake applications will help
to dry the brakes, thus preventing a reduc-
tion in braking performance caused by the
moisture.
To clean the handbrake, apply the lever
slightly at approx. 25 mph/40 km/h and con-
tinue to drive for approx. 200 yards/
200 meters, provided that traffic conditions
allow you to do so.
>Depending on the road condition, it can be
useful to temporarily activate DTC, refer to
DTC Dynamic Traction Control on page52.
>If the drive wheels spin on one side, depress
the accelerator pedal far enough to permit
the driving stability control systems to dis-
