Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, for
example by braking, steering or evading.
Engine power The desired speed is also maintained downhill,but may not be maintained on uphill grades if
engine power is insufficient.
Malfunction
The system cannot be activated if the radar
sensor is not aligned correctly. This may be
caused by damage incurred during parking, for
example.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be
limited in the following situations:▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept Using this system, a desired speed can be ad‐
justed using the buttons on the steering wheel.
The system maintains the desired speed. The
system accelerates and brakes automatically
as needed.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Information
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations.◀
WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀
WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively intervene in the respective situations.◀

Things to remember when drivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Breaking-in period General information
Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol.
Information WARNING
Due to new parts and components,
safety and driver assistance systems can react
with a delay. There is risk of an accident. After
installing new parts or with a new vehicle, drive
conservatively and intervene early if necessary.
Observe the break-in procedures of the re‐
spective parts and components.◀
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.▷For diesel engine 3,500 rpm and
93 mph/150 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
Driving on poor roads
The vehicle combines all-wheel drive with the
advantages of a normal automobile.
CAUTION
Objects in unpaved areas, for example
stones or branches, can damage the vehicle.
There is a risk of property damage. Do not
drive on unpaved terrain.◀

HillsWARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is risk of
an accident. Avoid placing excessive stress on
the brake system.◀
WARNING
In idle state or with the engine switched
off, safety-relevant functions are restricted or
not available anymore, e.g., braking effect of
the engine or braking force and steering sup‐
port. There is risk of an accident. Do not drive
in idle state or with the engine switched off.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by the fol‐
lowing circumstances:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
Driving on racetracksHigher mechanical and thermal loads during
racetrack operation lead to increased wear.
This wear is not covered by the warranty. The
vehicle is not designed for motorsports com‐
petitive use.Seite 185Things to remember when drivingDriving tips185

vehicle.
To start the engine with Steptronic transmis‐
sion:
1.Depress the brake pedal.2.Press the Start/Stop button.
Pressing the Start/Stop button without step‐
ping on the brake turns the ignition off.
Selector lever positionSelector lever position P is engaged automati‐
cally:
▷When the ignition is switched off.▷After approx. 15 minutes.
Headlights
▷Do not rub dry and do not use abrasive or
acidic cleansers.▷Soak areas that have been dirtied e. g.,
from insects, with shampoo and wash off
with water.▷Thaw ice with de-icing spray; do not use an
ice scraper.After washing the vehicle
After washing the vehicle, apply the brakes
briefly to dry them; otherwise, braking action
can be reduced and corrosion of the brake
discs can occur.
Completely remove all residues on the win‐
dows, to minimize loss of visibility due to
smearing and to reduce wiper noises and
wiper blade wear.
Vehicle care
Vehicle care products BMW recommends using vehicle care and
cleaning products from BMW.
WARNING
Cleansers can contain substances that
are dangerous and harmful to your health. There is a risk of injury. When cleaning the in‐
terior, open the doors or windows. Only use
products intended for cleaning vehicles. Fol‐
low the instructions on the container.◀
Vehicle paint
Regular care contributes to driving safety and
value retention. Environmental influences in
areas with elevated air pollution or natural con‐
taminants, such as tree resin or pollen can af‐
fect the vehicle's paintwork. Tailor the fre‐
quency and extent of your vehicle care to
these influences.
Aggressive substances such as spilled fuel, oil,
grease or bird droppings, must be removed im‐
mediately to prevent the finish from being al‐
tered or discolored.
Leather care
