Interior equipment
Integrated universal remote
control*
The concept
This system can replace up to three different
hand-held transmitters for various types of re‐
mote-controlled equipment, such as garage
doors or lighting systems.
The hand-held transmitter signal can be pro‐
grammed on one of the three memory buttons.
The
corresponding device can then be operated
using the programmed memory button.
The LED indicates that a signal is being trans‐
mitted.
When selling the vehicle, delete the stored pro‐
grams for security reasons.
During programming
During programming and before activat‐
ing a device using the universal remote control,
ensure that there are no people, animals, or ob‐
jects in the range of movement of the remote-
controlled device; otherwise, there is a risk of
injury or damage.
Also follow the safety instructions of the hand-
held transmitter.◀
Compatibility
If this symbol is printed on the packaging
or in the instructions of the hand-held
transmitter, the remote-controlled de‐
vice is generally compatible with the universal
remote control.
If you have any questions, please contact:
▷ Your service center.
▷ www.homelink.com on the Internet. Programming

LED, arrow 1.
▷ Memory buttons, arrow 2.
Fixed-code hand-held transmitters
1. Switch on the ignition.
2. Initial setup:
Press

both outer buttons 1 and 3 for approx.
20 seconds until the LED flashes.
All programs of the three memory buttons,
arrow 2, are cleared.
3. Hold the hand-held transmitter a distance of
approx.

2 to 8 in/5 to 20 cm from the memory
buttons.
4. Simultaneously press the transmit button of
the hand-held transmitter and the memory
button of the universal remote control.
The LED flashes slowly.
5. Release both buttons when the LED flashes
rapidly.

the LED does not flash rapidly after approx.
15 seconds, change the distance and repeat
the step.
The device can be operated using the memory
button with the engine running or the ignition
switched on.
Malfunction
If the device cannot be used after repeated at‐
tempts at programming, please check whether
the hand-held transmitter is equipped with an
alternating code system.

Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It
is advised that you do not use mobile commu‐
nication devices, e.g., mobile phones, inside the
vehicle without connecting them directly to the
external antenna. Otherwise, the vehicle elec‐
tronics and mobile communication devices can
interfere with each other. In addition, there is no
assurance that the radiation generated during
transmission will be discharged from the vehicle
interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀ Driving through water
Drive though calm water only if it is not deeper
than 9.8 inches/25 cm and at this height, no
faster

than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the elec‐
trical systems and the transmission may be
damaged.◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Objects in the area around the pedals
No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users. Seite 139

4.
The resulting figure equals the available
amount
of cargo and luggage load capacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs pas‐
sengers in your vehicle, the amount of avail‐
able cargo and luggage load capacity is
400 lbs: 1,000 lbs minus 600 lbs = 400 lbs.
5. Determine the combined weight of luggage
and

cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
Load The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷
Heavy cargo: stow as far forward and as low
as

possible, ideally directly behind the cargo
area separating wall.
▷ Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.
▷ Cover sharp edges and corners. Securing cargo
Lashing eyes in the cargo area
To secure the cargo, there are four lashing eyes
in the cargo area
Securing cargo
▷
Smaller and lighter items: secure with re‐
taining straps or with a

cargo net* or draw
straps.
▷ Larger and heavy objects: secure with cargo
straps*.
Cargo straps, cargo netting, retaining straps or
draw straps on the lashing eyes in the cargo
area.
Securing cargo
Always position and secure the cargo as
described

above; otherwise, it can endanger the
car's occupants if sudden braking or swerving
becomes necessary.
Heavy or hard objects should not be carried
loose inside the car; otherwise, they could be
thrown around as a result of hard braking, sud‐
den swerves, etc., and endanger the occu‐
pants.◀
Saving fuel
General information
Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.

ferent factors. Seite 141

▷ Seat, mirror, and steering wheel memory:
store the positions again.
▷ Time: update.
▷ Date: update.
▷ Radio station: save again.
▷ Navigation system: wait for the operability of
the navigation.
Disposing of old batteries Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport. Fuses
Notes
Replacing fuses
Never attempt to repair a blown fuse and
do
not replace a defective fuse with a substitute
of another color or amperage rating; this could
lead to a circuit overload, ultimately resulting in
a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box in
the cargo area.

Towing other vehicles
General information
Light towing vehicle
Your vehicle must not be lighter than the
vehicle being towed; otherwise, it will not be
possible to control vehicle response.◀
Attaching the tow bar/tow rope correctly
Attach the tow bar or tow rope to the tow
fitting; connecting it to other vehicle parts may
cause damage.◀
▷ Switch on the hazard warning system, de‐
pending on local regulations.
▷ If the electrical system has failed, clearly
identify the vehicle being towed by placing
a sign or a warning triangle in the rear win‐
dow.
Tow bar
The tow fittings used should be on the same
side on both vehicles.
Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:
▷ Maneuvering capability is limited during cor‐
nering.
▷ The tow bar will generate lateral forces if it
is secured with an offset.
Tow rope
When starting to tow the vehicle, make sure that
the tow rope is taut.
To avoid jerking and the associated stresses on
the vehicle components when towing, always
use nylon ropes or nylon straps.
Attaching the tow rope correctly
Only secure the tow rope on the tow fit‐
ting; otherwise, damage can occur when it is se‐
cured on other parts of the vehicle.◀ Tow fitting
The screw-in tow fitting should always be car‐
ried in the vehicle. It can be screwed in at the
front or rear of the BMW. It is contained in the
tool kit under the cargo floor cover.
Tow fitting, information on use
▷Use only the tow fitting provided with
the vehicle and screw it all the way in.
▷ Use the tow fitting for towing on paved roads
only.
▷ Avoid lateral loading of the tow fitting, e.g.,
do not lift the vehicle by the tow fitting.
Otherwise, damage to the tow fitting and the ve‐
hicle can occur.◀
Screw thread Push out the cover by pressing on the top edge.
