68 page 66. We recommend this program for 
performance-oriented driving. 
When you press the S/M/D button a sec-
ond time the transmission switches to its 
manual mode; press again to return to the 
automatic program. 
You can also return to the standard auto-
matic program by reselecting D. 
In the manual mode the transmission 
upshifts when you briefly press the buttons 
on the rear of the steering wheel. You 
downshift by briefly pressing the buttons 
on the front of the steering wheel. The Info 
Display shows the manual ranges M1 
through M6. 
Upshifts and downshifts are executed only 
when they will result in a plausible combi-
nation of engine and vehicle speed; thus, 
for example, a downshift that would cause 
the engine to overrev will not be executed 
by the system.  The selected gear appears 
briefly in the Info Display, followed by the 
current gear.
To obtain maximum acceleration, for 
passing maneuvers, etc., during 
operation in the manual mode, use the 
kickdown or downshift manually.< 
Malfunctions 
A status report will appear in the Check 
Control to alert you to any malfunctions in 
the transmission-control system. Please 
note any supplementary information that 
appears on the Control Display. The direc-
tional arrows also start to flash in the Info 
Display. 
While it will remain still possible to move 
the selector lever to any desired position, 
the transmission will revert to operation in 
its default mode with only a limited number 
of forward gears. 
Some types of malfunction will make it 
impossible to engage all gears. 
The engine may respond with reduced out-
put when accelerating from a standing 
start. If this happens, avoid extreme engine loads 
and consult the nearest BMW center. 
If no status messages appear in the 
Info Display you should accelerate 
carefully to confirm that you are driving in 
the desired direction. 
Never work in the engine compartment 
with any of the forward or reverse gears 
engaged, as the vehicle could start to 
move. Engaging the parking brake, refer to 
page 62.< 
Manual release of transmission 
lockout 
You can respond to any interruptions in the 
supply of electrical power, for instance, if 
the battery is discharged or disconnected, 
by releasing the transmission lockout man-
ually. 
To prevent the drive wheels from 
locking up and sliding, the transmis-
sion lockout must always be released man-
ually before the vehicle is towed.< 
Press the brake pedal before releas-
ing the transmission lockout manu-
ally. If the brakes are not applied, the vehi-
cle could start to roll if parked on a steep 
slope. 
The transmission lockout should only be 
released for towing. Remember to engage 
the transmission lockout when you repark 
the vehicle after moving it. 
Should it also be necessary to release 
the parking brake manually, owing to a dis-
charged battery, etc., always adhere to the 
following sequence: 
1.Start by manually releasing the parking 
brake, refer to page 64 
2.Then proceed to manually release the 
transmission lockout.< 
Jump-starting and towing, refer to 
pages 207 and 208.

when you select the AUTO program. 
Temperature adjustment 
You can turn to select the 
desired temperatures for the 
driver and passenger sides. 
Your settings appear on the 
Control Display's status line. 
The figures in the display provide a general 
indication of interior temperature. When 
you start the vehicle, this system ensures 
that the selected temperature is achieved 
as quickly as possible. It then maintains 
this temperature, regardless of the season. 
Defrosting windows and removing 
condensation 
This program quickly removes 
ice and condensation from the 
windshield and door windows. 
Adjusting air supply manually 
You can adjust the air supply by 
turning. The automatic air sup-
ply control is operational when-
ever you see your selection 
represented by a bar on the 
Control Display's status line. The automatic 
air distribution remains in operation as 
before. You can reactivate the automatic 
air supply mode with the AUTO button. 
Switching air conditioner mode on 
and off manually
The air conditioner cools and 
dehumidifies the incoming air 
before also reheating it as 
required, according to temperature setting. 
Depending on the weather, the windshield 
may fog over briefly when the engine is 
started. 
The air conditioner comes on automatically 
when you select the AUTO program. 
Maximum cooling 
This program quickly provides 
maximum cooling. 
The temperature display reverts 
to 607/166 while the system 
switches to the recirculated-air mode and 
starts to provide maximum air supply 
through the vent outlets only. For this rea-
son you should ensure that these outlets 
are open before selecting this program.
Outside air/AUC Automatic 
recirculated-air control/
recirculated air 
You can respond to unpleasant 
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air. 
The system then recirculates the air cur-
rently within the vehicle. AUC executes this 
function automatically. 
Press the button repeatedly to run through 
the following control sequence: 
>Indicator lamps off: outside air flows 
into the vehicle 
>Left indicator lamp on, AUC mode: the 
system detects pollutants in the outside 
air and responds by blocking the supply 
of outside air when required. The sys-
tem then recirculates the air currently 
within the vehicle. 
Depending upon air quality, in the auto-
matic mode the system may start to 
alternate between its outside-air and 
recirculated-air modes 
>Right indicator lamp on, recirculated-
air mode: the supply of outside air into 
the vehicle is permanently blocked. 
The system then recirculates the air 
currently within the vehicle. 
If condensation starts to form on the 
inside window surfaces during opera-
tion in the recirculated-air mode, you 
should switch it off while also increasing air 
supply as required.<

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 
>For very heavy cargo when the rear seat 
is not occupied, secure each safety belt 
in the opposite buckle. 
Securing cargo 
>Use the luggage net* or securing straps 
to hold down small and lightweight lug-
gage and cargo, refer to page 39 
>Heavy-duty cargo straps
* for securing 
larger and heavier objects are available 
at your BMW center. Anchorages for 
attaching these heavy-duty straps have 
been provided in your vehicle's luggage 
compartment, refer to the illustration
>Please observe the special instructions 
supplied with the anchorage fittings. 
Always position and secure the load 
correctly. 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 214, 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 
pose a safety hazard to the vehicle's occu-
pants during abrupt braking or evasive 
maneuvers .< 
Roof-mounted luggage 
rack*
Anchorage points 
The anchorage points are located within 
the door openings. 
A special rack system is available as an 
option for your BMW. Please comply with 
the precautions included with the installa-
tion instructions. 
Because roof racks raise the vehicle's cen-
ter of gravity when loaded, they have a 
major effect on its handling and steering 
response. 
You should therefore always remember not 
to exceed the approved roof weight, the 
approved gross vehicle weight or the axle 
loads when loading the rack. 
You can find the specified weights in the 
Technical data section on page 214. 
Make sure that the load is not too heavy, 
and that it does not extend outward to 
beyond the limits of the loading surface. 
Always load the heaviest pieces first Ð on 
the bottom. Be sure that adequate clear-
ance is maintained for raising the glass 
roof, and that objects do not project into  
Page 128 of 232
Things to remember when driving
126 the opening path of the luggage compart-
ment lid. 
Secure roof-mounted cargo correctly and 
securely to prevent it from shifting or being 
lost during the trip. 
Drive smoothly. Avoid sudden acceleration 
and braking maneuvers. Take corners gen-
tly. 
Entry/pass tags 
Infrared windshield technology has been 
used on your vehicle to minimize solar 
heating of the vehicle interior. This technol-
ogy also reduces the ability of electronic 
devices to transmit and receive through 
the windshield, which will impair their per-
formance and operating range. 
If you want to place an electronic toll col-
lection device or entry/pass tags behind 
the windshield, please use the area marked 
in the illustration. This area is clearly visible 
from inside the vehicle. 
Standard holder*
Remove the protective cap, insert the stan-
dard and lock in place by turning by 901.
At high speeds, remove the standard, 
as otherwise the standard, standard 
holder and vehicle can be damaged.<

Releasing 
Pull the lever located under the left side of 
the instrument panel. 
Never attempt to perform any service 
or repair operations on your vehicle 
without the required, professional technical 
training. When you are unfamiliar with the 
service procedures and precautions, 
always have any required work carried out 
at your BMW center. Otherwise, the incor-
rect handling of parts and materials that 
can occur during such attempts constitutes 
a potential safety hazard, both for the vehi-
cle's occupants and for other road users.<
Opening 
Pull the release handle and open the hood. 
Closing 
Close the hood from a height of approx. 
16 in/40 cm with momentum. It must be 
clearly heard to engage. 
Observe the same precautions that 
apply to all closing operations by 
ensuring that the hood's travel range is 
clear and unobstructed before allowing the 
hood to fall into position. 
If you see any signs that the hood is not 
completely closed while you are driving 
your vehicle, you should stop at once and 
close it securely.<

Change the wheel only on a level, firm sur-
face which is not slippery. The vehicle or 
the jack could slip to the side if you attempt 
to raise the vehicle on a soft or slippery sur-
face such as snow, ice, tiles, etc.  
Position the jack on a firm support surface.
Do not use a wooden block or similar 
object as a support base for the jack, as 
this would prevent it from extending to its 
full support height and reduce its load-car-
rying capacity.
To avoid serious or fatal injury: never lie 
under the vehicle, and never start the 
engine while it is supported by the jack.< 
What you will need 
To avoid rattling noises, note the positions 
of the tools before removing them, then 
return them to their initial positions after 
completing work. 
>Lug wrench 
Located beside the spare tire 
>Wheel chock 
The chock is located next to the spare 
tire, or behind the trim panel on the left 
side of the luggage compartment on 
vehicles equipped with a trailer cou-
pling. Remove the floor mat and the cover 
above the spare tire. 
Unscrew the wingnut and remove the 
wheel chock 
>Jack 
The jack is located behind the side trim 
panel on the right side of the luggage 
compartment. 
Grasp the handle in the upper panel 
and fold it down. 
Unscrew the wingnut and remove the 
jack. 
After use, screw the jack all the way 
back down and snap the handle back 
into place.

Replacing components
204 surface of the front tire on the side 
opposite the side being raised. If the 
vehicle is parked on a downward slope, 
place the wheel chock securely in front 
of the tire. If the wheel must be changed 
on a surface with a more severe slope, 
take additional precautions to secure 
the vehicle from rolling
3.Loosen the lug bolts 1/2 a turn 
4.Set up the jack beneath the jacking 
point closest to the flat tire. Ensure that 
the entire surface of the jack's base is in 
firm contact with the ground and that 
the jack itself is standing completely 
vertical, not tilted, and that the fitting on 
the top of the jack will align with the 
rectangular recess on the vehicle when 
you raise it, refer to illustration 
5.Jack the vehicle up until the wheel you 
are changing is raised from the ground 
6.Unscrew the lug bolts and remove the 
wheel 
7.Remove accumulations of mud or dirt 
from the mounting surfaces of the 
wheel and hub. Clean the lug bolts 
8.Position the spare wheel. Secure the 
wheel by turning at least two lug bolts 
into opposite bolt holes 
9.Screw in the remaining lug bolts. 
Tighten all the bolts securely in a diag-
onal pattern 
10.Lower the jack and remove it from 
beneath the vehicle 
11.Tighten the lug bolts in a diagonal pat-
tern 
12.Check and correct the tire inflation 
pressure at the earliest opportunity. Protect valve stems and valve stem 
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source 
of gradual air loss.< 
After mounting the spare wheel or correct-
ing the inflation pressure, reinitialize the 
Flat Tire Monitor, refer to page 95. 
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.
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 specified torque.
The tightening torque is 101 ft-lb/
140 Nm.< 
Reverse the removal sequence to store the 
wheel and tools in the vehicle. 
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug 
bolts may also be required.
Always have damaged tires replaced and 
the wheel and tire assembly rebalanced at 
the earliest possible opportunity. 
Driving with the spare tire
On certain wheel-tire combinations, 
the size of the spare tire deviates from 
that of the rest of the tires. The spare tire is 
fully capable of running in all load and 
speed ranges. However, to recreate the 
original conditions, the tire should be 
replaced as soon as possible.<
