suspension BMW Z4 2015 E89 Owner's Manual

For your own safetyWarranty
Your vehicle is technically configured for the
operating conditions and registration require‐
ments applying in the country of first delivery
— homologation. If your vehicle is to be oper‐
ated in a different country it might be neces‐
sary to adapt your vehicle to potentially differ‐
ing operating conditions and permit
requirements. If your vehicle does not comply
with the homologation requirements in a cer‐
tain country you cannot lodge warranty claims
for your vehicle there. Further information can
be obtained from your Service Center.
Maintenance and repairs Advanced technology, e.g., the use of modern
materials and high-performance electronics,
requires suitable maintenance and repair
methods.
Therefore, have this work performed only by a
BMW center or a workshop that works accord‐
ing to BMW repair procedures with appropri‐
ately trained personnel.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.
Parts and accessories For your own safety, it is recommended that
you use genuine parts and accessories ap‐
proved by BMW. When you purchase accesso‐
ries tested and approved by BMW and Genu‐
ine BMW Parts, you simultaneously acquire
the assurance that they have been thoroughly
tested by BMW to ensure optimum perform‐
ance when installed on your vehicle. BMW
warrants these parts to be free from defects in
material and workmanship. BMW will not ac‐
cept any liability for damage resulting from in‐
stallation of parts and accessories not ap‐
proved by BMW. BMW cannot test every
product made by other manufacturers to verify
if it can be used on a BMW safely and withoutrisk to either the vehicle, its operation, or its
occupants. Genuine BMW Parts, BMW Acces‐
sories and other products approved by BMW,
together with professional advice on using
these items, are available from all BMW cen‐
ters. Installation and operation of non BMW
approved accessories such as alarms, radios,
amplifiers, radar detectors, wheels, suspension
components, brake dust shields, telephones,
including operation of any mobile phone from
within the vehicle without using an externally
mounted antenna, or transceiver equipment,
for instance, CBs, walkie-talkies, ham radios or
similar accessories, may cause extensive dam‐
age to the vehicle, compromise its safety, in‐
terfere with the vehicle's electrical system or
affect the validity of the BMW Limited War‐
ranty. See your BMW center for additional in‐
formation. Maintenance, replacement, or repair
of the emission control devices and systems
may be performed by any automotive repair
establishment or individual using any certified
automotive part.

car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.◀
RSC – Run-flat tires The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
page 234.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
XL
Designation for specially reinforced tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Indications of tire damage or other vehicle de‐
fects:
▷Unusual vibrations during driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; other‐
wise, there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.
