tion only.
After removing the key, turn the steering wheel
slightly to the left or right until you hear the lock
engage.
Interlock with automatic transmission
The key can only be turned back to position0 or
removed if the selector lever is in position P:
interlock.
Steering unlocked
A slight steering wheel movement often makes
it easier to turn the key from0 to1.
Some power accessories are ready for opera-
tion.
Ignition switched on
All vehicle systems are ready for operation.
Starting engine
Do not run the engine in enclosed spaces;
otherwise, inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Do not leave the vehicle unattended with the
engine running, since an unattended vehicle
with a running engine is a safety hazard.
To prevent the vehicle from rolling, always shift
into neutral or selector lever position P and
engage the handbrake firmly before leaving the
vehicle with the engine running.<
Do not discontinue the starting procedure pre-
maturely, but also do not prolong it for more
than 20 seconds. Release the ignition key
immediately as soon as the engine starts.
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up while
parked; instead, start driving immediately at a
moderate engine speed.
Indicator lamps
The warning lamp lights up. Exhaust
values are deteriorating. Have the vehi-
cle checked as soon as possible.
Under certain conditions, the indicator will flash.
This indicates a serious rate of engine misfire.
When this occurs, you should reduce speed
and consult the nearest BMW Sports Activity
Vehicle Center as soon as possible. Severe
engine misfire, even for only a short period of
time, can seriously damage emission control
components, especially the catalytic converter.

function on Canadian models.
If one of the malfunctions described
below occurs, drive with restraint and
caution and avoid full braking; otherwise, acci-dents can occur. When driving on poor road
surfaces, avoid full throttle or kickdown position
of the accelerator pedal as these could cause
damage to the drive system.<
The warning lamp for the brake system
lights up in red, together with the warn-
ing lamps for ABS and DSC/xDrive. In
addition, a warning signal sounds.
The driving stability control systems
have failed. It is then possible to exert
driving force only via the rear axle.
If the brake system warning lamp lights
up in yellow in the described combination, then
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.
Display of the previously described mal-
function on Canadian models.
The warning lamp lights up continu-
ously and a warning signal sounds:
Both DSC and DTC or the xDrive all-
wheel drive system have failed.
The stabilizing interventions of DSC or the all-
wheel drive system xDrive are no longer avail-
able. It is then possible to exert driving force
only via the rear axle. Have the system checked
as soon as possible.
Acceleration assistant
The acceleration assistant allows you to conve-
niently start off on inclines. You do not have to
use the handbrake.
1.Hold the vehicle with the brake pedal.
2.Step off the brake and immediately start off
with no trouble.
The acceleration assistant holds the vehi-
cle for approx. 2 seconds after the brake
is released. Depending on the load or when
towing a trailer, it is also possible for the vehicle
to roll backward slightly during this interval.

After releasing the brake, start driving immedi-
ately; otherwise, the acceleration assistant will
no longer hold the vehicle after approx. 2 sec-
onds and the vehicle will start to roll back-
ward.<
Malfunction
The warning lamp for the brake system
lights up in yellow. The acceleration
assistant has failed. The vehicle will not
be held after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure in one tire drops signifi-
cantly in relation to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be carried out after
each correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot predict sud-
den severe tire damage caused by out-
side factors and does not detect a natural, even
pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>When the system has not been initialized
>When driving on snow-covered or slippery
road surfaces>Sporty driving style: slip in the drive wheels,
high lateral acceleration.
>When driving with snow chains
*
When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
The initialization is completed while driv-
ing and can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Do not initialize the system when driving with
snow chains
* or with a compact wheel.<
1.Start the engine just before driving, but do
not begin to drive.
2.Press the button for at least 4 seconds, but
not longer than 2 minutes. After the button
is released, the indicator lamp in the instru-
ment cluster lights up yellow for a few sec-
onds.
3.Begin driving.
The initialization is completed while driving,
without requiring any further input from you.
Indication of a flat tire
The warning lamp lights up red. In addi-
tion, an acoustic signal sounds. There is
a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<

The compact wheel is not equipped with the
required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.
Have the damaged tire replaced by your BMW
Sports Activity Vehicle Center or a workshop
that is familiar with TPM and works in accor-
dance with BMW repair procedures, using
appropriately trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. Flat tires
cannot be detected.
Such a message is displayed in the following
situations:
>When a malfunction is occurring:
Have the system checked
>When a wheel without TPM electronics is
mounted, e.g. a compact wheel
>When TPM is experiencing temporary inter-
ference from other systems or devices that
use the same frequency
NHTSA/FMVSS-required explanation
of 138 Tire Pressure Monitoring
System
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
then you should determine the proper tire infla-
tion pressure for those tires. As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system, TPMS, that
illuminates a low tire pressure warning lamp
when one or more of your tires are significantly
under-inflated. When the low tire pressure
warning lamp lights up, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly underinflated tire causes the tire to over-
heat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability. Please note that the TPMS is not a
substitute for proper tire maintenance, and it is
the driver's responsibility to maintain correct
tire pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure warning lamp.
The TPMS malfunction indicator is combined
with the low tire pressure warning lamp. When
the system detects a malfunction, the warning
lamp will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction warning lamp after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.Brake force display
The brake lamps light up in two stages,
depending on how heavily you apply the brakes.
>Normal braking
The brake lamps and the center brake lamp
light up.
>Heavy braking
The rear fog lamps light up as well.

Things to remember when driving
82
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page40. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page51.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimal
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Brake pads
The warning lamp lights up.
The brake pads have reached their min-
imum pad thickness. Have brake pads
replaced immediately.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating of the tire and increases the rate at
which damage develops inside the tires. The
ultimate result can assume the form of a sudden
blow-out.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
990 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
240 lbs.:
990 lbs. minus 750 lbs. = 240 lbs.

Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sports
Activity Vehicle Center for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
are harmful to your health, so follow the instruc-
tions on the containers.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.Allow engine to cool.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct when it is
between the MIN and MAX marks, also refer
to illustration next to filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Screw on the cap and tighten snugly.
6.Have the reason for the coolant loss cor-
rected as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights up red despite
the handbrake being released.
The brake fluid in the reservoir has
fallen to below the minimum level. At the same
time, a considerably longer brake pedal travel
may be noticeable. Have the system checked
immediately.
During continued driving, increased brake
pedal travel may be necessary, and con-
siderably longer braking distances may result.
Please adapt your driving style accordingly.<
