For maximum safety, please comply 
with the following instructions when ad-
justing a seat:
Never try to adjust your seat while 
operating the vehicle. The seat 
could respond with unexpected move-
ment, and the ensuing loss of vehicle 
control could lead to an accident. 
Wear the safety belt firmly against your 
body at all times. In the event of a fron-
tal impact, a loose lap belt could slide 
over your hips, leading to abdominal 
injury. In addition, the safety belt's 
restraint effectiveness is reduced if the 
belt is worn loosely.
Never ride with the backrest reclined to 
an extreme horizontal angle (especially 
important for front passengers to 
remember). Keep the backrest relatively 
upright to minimize the risk of "sliding 
under" the safety belt and sustaining 
injury in an accident.
Do not slide the seats to the rear 
when the vehicle is at an extreme angle 
(on garage ramps or steep slopes, for 
instance), to prevent the shoulder 
strap's automatic height adjustment 
mechanism from disengaging.< 
Correct sitting postureTo reduce strain on the spinal column, 
sit all the way back in the seat and rest 
your back fully against the backrest.
The ideal sitting posture is achieved 
with your head extending from your 
spine in a straight line.
For long-distance driving, you may wish 
to increase the backrest tilt-angle 
slightly to reduce muscular tension. 
Please remember that you should 
always remain able to grasp the entire 
periphery of the steering wheel without 
straightening your arms.1 Tilt angle (only driver's side)
2 Forward/backward adjustment
3 Cushion height
4 Backrest angle
5 Head restraint height
Adjust the angle of the head restraints 
by tilting the head restraint, refer to 
page 53.
Read and comply with the adjust-
ment instructions in the previous 
column. Failure to do so can result in 
diminished personal safety.<

Pull the lever and slide the seat to the 
desired position.
After releasing the lever, apply pres-
sure to the cushion to ensure that the 
latch engages securely

or remove weight from the seat as 
required390de682
3 Backrest angle
Pull the lever and apply weight to or 
remove weight from the backrest to 
reach the desired position
Comply with the adjustment in-
structions on page 52. Failure to 
do so could result in diminished perso-
nal safety.< 390de683
Head restraintsTo adjust the angle of the front head 
restraints: adjust by tilting the head 
restraint.
To adjust the height of the front pas-
senger and rear head restraints: adjust 
by pulling up or pressing down.
Head restraints reduce the risk 
of spinal injury in the event of an 
accident. 
Adjust the head restraint so that its 
center is approximately level with your 
ears. 
Leave the center rear head restraint in 
the fully-lowered position at all times, 
since pulling it out limits its function.<390de065

Overview
159nHood
To unlock
Pull the lever located under the left- 
hand side of the instrument panel.
Do not work on your vehicle with-
out appropriate skills. Switch off 
the engine and allow it to cool down 
before working in the engine compart-
ment. Always disconnect the battery 
before working on any electrical 
systems or equipment, especially when 
these are located within the engine 
compartment. Comply with all applica-
ble instructions and warnings. Failure to 
work in an informed, professional 
manner when servicing components 
and materials constitutes a safety 
hazard for vehicle occupants and other 
road users. If you are not familiar with 
the guidelines, please have the opera-
tions performed by your authorized 
BMW center. <
390de071
To open
Pull the release handle and open the  
hood.
390de072
To close
Allow the hood to fall from a height  
of about 12 in (30 cm) so that it audibly 
engages.
To avoid injuries, be sure that the 
travel path of the hood is clear 
when it is closed, as with all closing 
procedures.
If it is determined that the hood is not 
completely closed while driving, stop 
immediately and close it securely. <

190nChanging a wheel 
Safety measures in the event of a  
flat tire or wheel change:
Stop the vehicle as far as possible from 
passing traffic. Park on a firm, flat, 
surface. Switch on the hazard warning 
flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and 
engage the steering lock. Shift into 1st 
or reverse (selector lever in Park with 
automatic transmission) and engage 
the parking brake. 
All passengers should be outside the 
vehicle and well away from your imme-
diate working area (behind a guardrail, 
for instance).
If necessary, set up your warning trian-
gle or portable hazard warning lamp on 
the roadside at an appropriate distance 
from the rear of the vehicle. Comply 
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm 
surface which is not slippery. Avoid 
jacking the vehicle on a soft or slippery 
support surface (snow, ice, loose 
gravel, etc.), since it could slide side-
ways.Position the jack on a firm support  
surface. 
Do not place wooden blocks or similar 
objects  under the jack. If this is done, 
the jack might not be able to reach its 
full support capacity because of the 
limited height. 
Do not lie under the vehicle or start the 
engine when the vehicle is supported 
by the jack – risk of fatal injury. < 
What you will need
In order to avoid rattling noises later, 
note the position of the tools when you 
remove them and return them to their 
original position when you are through 
using them. 
> Car jack  
sedan: fold back the luggage com-
partment floor mat for access, then 
unscrew the wingnut to release the 
jack (arrow).
sport wagon: raise the floor panel 
and spare tire cover (refer to 
page  134).
When you have completed work, 
screw the jack all the way back 
down. Fold the handle back and in-
sert it in its holder
> Wedge (wheel chock)
Located next to the jack. Loosen the 
wing nut to remove it

214nIntegrated rear suspension Level control system*
The control arms on the patented inte- 
grated aluminum rear axle assembly are 
not mounted directly on the body. They 
are mounted elastically on a chassis 
sub-frame which is joined in turn with 
elasticity to the vehicle body. The result-
ing double elastic suspension system 
effectively absorbs the forces resulting 
from bumps and road surface irregulari-
ties. 
The compliance rates of the integrated  
rear axle assembly's control arm mounts 
have been precisely calibrated to help 
provide supplementary adjustment in 
the tracking angle of the rear wheels 
(programmed self-steer effect). The ulti-
mate result is enhanced safety and con-
trol under all conditions.
390de114
The illustration shows the rear axle of the  
sedan. With the lightweight, compact 
rear axle of the sport wagon, the shock 
absorbers are positioned at an angle.
The level control system for the rear 
axle maintains constant ground clear-
ance of your vehicle, even when carry-
ing a load. 
To achieve this, the vehicle is equipped  
with air struts at the rear axle instead of 
conventional shock absorbers and steel 
suspension springs. With the help of 
two sensors, an electronic control unit 
calculates the height of the body at all 
times and, if it is required, it allows air 
which is generated in a compressor to 
flow into the air springs. 
As a result of the pressure increase in  
the air springs, the level control system 
ensures not only constant ride height, 
but also ride comfort which is indepen-
dent of the load the vehicle is carrying.
