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.

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact wheel: at least twice a month and
before starting long trips. If you fail to observe
this precaution, you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. flat tires. A flat tire
will seriously impair your vehicle's handling and
braking response. Attempts to drive on a flat tire
can lead to loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to pages53,
54.<
Pressure specifications
The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation. tion pressure for your tires, please note the fol-
lowing:
>Tire size for your vehicle
>Load status
>Maximum permissible driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving at speeds of up to 100 mph/
160 km/h and to achieve optimum driving com-
fort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.
The maximum permissible speed for
these tire inflation pressures is 100 mph/
160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds
above 100 mph/160 km/h, take note of
the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.<

age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. The causes for this include the
possibly different tire casing structures and the
often wide variations in their age, which can
result in a limited service life.<
Correct wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact and with it, the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After tire
damage, always remember to have the original
wheel and tire combination remounted on the
vehicle as soon as possible.
Wheels equipped with electronics for
TPM Tire Pressure Monitor
When installing new tires or when changing
from summer tires to winter tires or vice versa,
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page54. Your
BMW Sports Activity Vehicle Center will be
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires do provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and
fuel. Do not exceed the maximum tire inflation
pressure indicated on the side wall of the tire.
Changing wheels from one axle to
another
BMW does not recommend changing the front
wheels to the back or vice versa as this can
impair handling characteristics.

Inserting compact wheel
The compact wheel is reinserted in the reverse
sequence of its removal.
When attaching the retaining strap to the
compact wheel, make sure the belt is
threaded through 2 rim openings, with one
unoccupied hole between them; otherwise, the
compact wheel could come loose in an acci-
dent.<
Preparing wheel change
1.Observe the safety precautions on
page109.
2.Secure the vehicle to prevent it from rolling:
Place the wheel chock behind the front
wheel on the side of the vehicle opposite
the side being raised. If the vehicle is parked
on a downward slope, place the wheel
chock securely in front of this wheel. If the
road surface is steeply inclined, take addi-
tional preventive steps to stop the vehicle
from rolling.
3.Loosen the wheel lugs by a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base perpendicularly con-
tacts the ground under the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to drawing inset.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes. When you
mount wheels other than Genuine BMW
light-alloy wheels, different lug bolts may
also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the jack and remove it from beneath
the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the lug
bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
101 lb ft/140 Nm.<
2.Stow the defective wheel in the cargo area.
3.Check and correct the tire inflation pressure
at the earliest opportunity.

Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages53, 54.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page114.
