Brakes: 
Do not drive with your foot resting 
on the brake pedal. Even light but 
consistent pedal pressure can lead to 
high temperatures, brake wear, and 
possibly to brake failure. 
Aquaplaning: 
When driving on wet or slushy roads, 
reduce vehicle speed. If you do not, a 
wedge of water may form between the 
tires and the road surface. This 
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized by a partial or complete loss of 
contact between the tires and the road 
surface. The ultimate results are loss of 
steering and braking control. 
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. Otherwise, the 
vehicle's engine, the electrical systems 
and the transmission may be damaged. 
Clothes hooks (for the hardtop): 
When suspending clothing from the 
hooks, be sure that they will not 
obstruct the driver's vision. Do not hang 
heavy objects on the hooks. If you do 
so, they could cause personal injury 
during braking or evasive maneuvers.<
The catalytic converter reduces harmful 
exhaust emissions.
It is designed for use with unleaded fuel 
only. Even minute quantities of lead 
would be enough to permanently 
damage both the catalytic converter 
and the system oxygen sensor.
To ensure efficient, trouble-free engine 
operation and to avoid potential 
damage:
>Be sure to comply with the scheduled 
maintenance requirements.
>Fill the fuel tank well before it is 
empty.
>Tow-start only when the engine is 
cold. If you attempt to tow-start with 
a warm engine, unburned residual 
fuel in the catalytic converter could 
ignite and cause damage. It is better 
to jump-start the vehicle with outside 
assistance.
>Avoid other situations in which the 
fuel is not burned, or burns incom-
pletely, such as engaging the starter 
frequently or for extended periods, or 
repeated start attempts in which the 
engine does not start (stopping and 
restarting an engine which is running 
properly does not present a problem). 
Never allow the engine to run with 
any of the spark plug cables discon-
nected.Be sure to comply with the 
preceding instructions to prevent 
unburned fuel from reaching the cata-
lytic converter. If you do not, the cata-
lytic converter could respond by 
overheating, leading to serious 
damage. 
Very high temperatures occur in any 
vehicle equipped with a catalytic 
converter. Heat shields are installed 
adjacent to some sections of the 
exhaust system. Never remove these 
shields; do not apply undercoating to 
their surfaces. When driving, standing 
at idle, and parking the vehicle, take 
extra care to avoid contact between the 
exhaust system and flammable mate-
rials (grass, hay, leaves, etc.). Such 
contact could lead to a fire, resulting in 
serious personal injury and property 
damage.<

Information for your safetyThe factory-approved radial tires are 
matched to the vehicle and have been 
selected to provide optimum safety and 
driving comfort on your vehicle. 
It is not merely the tire's service life, but 
also driving comfort and Ð above all 
else Ð driving safety that depend on the 
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a frequent 
cause of tire damage. It also signifi-
cantly influences the roadholding ability 
of your BMW.
Be sure to check the tire inflation 
pressure Ð including the space-
saver spare tire Ð on a regular basis, i.e. 
at least twice a month and before 
beginning a longer trip. Refer to 
page 28. If this is not done, incorrect 
tire pressures can cause driving insta-
bility and tire damage, ultimately 
resulting in an accident.<
Tire tread Ð tire damageInspect your tires frequently for tread 
wear, signs of damage and for foreign 
objects lodged in the tread. Check the 
tread depth. 
Tread depth should not be allowed to 
go below 0.12 in (3 mm), even though 
the legally specified minimum tread 
depth is only 0.063 in (1.6 mm). At a 
tread depth of 0.063 in (1.6 mm), tread 
depth indicators (arrow) in the tread-
groove base indicate that the legally-
permissible wear limit has been 
reached. Below 0.12 in (3 mm) tread 
depth, there is an increased risk of 
aquaplaning, even at relatively 
moderate speeds and with only small 
amounts of water on the road.390de331
Do not drive on a deflated (flat) 
tire. A flat tire greatly impairs 
steering and braking response, and can 
lead to complete loss of control over 
the vehicle. 
Avoid overloading the vehicle so that 
the permitted load on the tires is not 
exceeded. Overloading can lead to 
overheating and increases the rate at 
which damage develops inside the 
tires. You could have a blowout as a 
result. 
Unusual vibrations encountered during 
normal vehicle operation can indicate 
tire failure or some other vehicle defect. 
This is also true for irregularities in the 
vehicle's handling characteristics, such 
as a pronounced tendency to pull to the 
left or right. Should this occur, respond 
by immediately reducing your speed. 
Proceed carefully to the nearest BMW 
center or professional tire center, or 
have the vehicle towed in to have it and 
its tires inspected. 
Tire damage (up to and including blow-
outs) can endanger the lives of both the 
vehicle occupants and other road 
users.<
