road surface. This phenomenon is referred
to as hydroplaning, and is characterized
by a partial or complete loss of contact
between the tires and the road surface, ulti-
mately undermining your ability to steer
and brake the vehicle.<
The risk of hydroplaning increases as the
tread depth of the tires decreases, also
refer to Tire tread on page 167.
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Braking safely
Your BMW is equipped with ABS as stan-
dard. The best way to achieve optimized
braking response from the ABS is to apply
maximum pressure to the brake pedal in
situations where this is required: panic
stops. Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a minimum
of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.<
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to ensure
that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to
ensure that full braking efficiency will then
be available when you need it.
Hills
To prevent overheating and thus
reduced efficiency of the brake sys-
tem, downshift to a gear in which only min-
imal brake applications are needed when
descending long or steep downhill
stretches. Even light but consistent pedal
pressure can lead to high temperatures,
brake wear and possibly even brake fail-
ure.<
You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
page 59. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never drive with the clutch pressed
or allow the vehicle to coast with the
transmission in Neutral – or with the engine
switched off – there is no engine braking
when the transmission is in Neutral, and no
power assist for brakes and steering when
the engine is not running.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion on brake rotors
When the vehicle is driven only occasion-
ally, 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 ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimum
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 pul-
sating effect that even extended applica-
tion will fail to cure.

Stowing cargo
>Load heavy cargo as far forward and
as low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners.
Securing cargo
>Use the luggage net* or securing straps
to hold down small and lightweight lug-
gage and cargo
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available
at your BMW center. Four lashing eyes
fitted in the luggage compartment are
used to secure these heavy-duty cargo
straps, refer to arrows
>Please observe the special instructions
supplied with the heavy-duty cargo
straps.
Always position and secure the load
as described above. If you do not, it
can even endanger the passengers during
braking or evasive maneuvers.
Never exceed either the approved gross
vehicle weight or either of the approved
axle loads, refer to page 190, as excessive
loads can pose a safety hazard, and may also place you in violation of freeway safety
laws.
You should never transport heavy or hard
objects unsecured in the passenger com-
partment, as they could fly around and
even pose a safety hazard to the vehicle's
occupants during abrupt braking or evasive
maneuver.<
Pad on base of luggage
compartment
If required, you can use the pad e.g. to
transport dirty or soiled objects. The rub-
berized side is washable and has an anti-
slip effect.

Fuel specifications
The engine uses lead-free gasoline only.
Required fuel
Premium Unleaded Gasoline,
Minimum Octane Rating: 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called (R+M)/
2 method.
Do not use leaded gasoline, as other-
wise the lambda probe and catalytic
converter will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant
differences in fuel quality: volatility, compo-
sition, additives, etc., among gasolines
offered for sale in the United States and
Canada. Fuels containing up to and includ-
ing 10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight, that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and stall-
ing problems, especially under certain
environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may also result in unscheduled main-
tenance.<

Recommended tire sizes and makes
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
In the event of replacement, use run-flat
tires, refer to page 168, as there is no spare
wheel available for flats.
For safety reasons, BMW recom-
mends that you do not have damaged
run-flat tires repaired; they should be
replaced.<
Special characteristics of winter
tires
BMW recommends winter tires for use in
cold winter driving conditions. Although all-
season M+S tires provide better winter
traction than summer tires, they generally
fail to provide the same levels of cold-
weather performance as winter tires.
Run-flat tires
If you switch from summer to winter tires,
or vice versa, use run-flat tires, refer to
page 168, as in the event of a flat tire there
is no spare tire available. Your BMW center
will be glad to advise you.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with the required professional knowledge and
specialized equipment.<
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels. Do not
exceed the maximum tire inflation pressure
indicated on the side wall of the tire.
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels
with the tire size 245/45 R 18.
Observe the manufacturer's instructions
when mounting snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with the chains mounted.
Do not initialize the Runflat Indicator
after mounting snow chains.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 77.<
