The Tele Aid system consists of three types
of response:
R Automatic and manual emergency
R Roadside Assistance
R Information
The Tele Aid system is operational providing
that

the vehicle’s battery is charged, properly
connected, not damaged, and cellular and
GPS coverage is available. The Tele Aid
system utilizes the cellular network for
communication and the GPS ( Global
Positioning System) satellites for vehicle
location. If either of these signals are
unavailable, the Tele Aid system may not
function and if this occurs, assistance must
be summoned by other means.
i A Tele Aid call cannot be canceled. Even
if the Tele Aid system is not activated or
operational, the system will attempt to
connect the respective call. This may take
as

long as five minutes or more. As long as
the Tele Aid system attempts to connect a
call, you cannot operate the COMAND
system. Also, most functions in the control
system, such as the telephone function, are
suspended. Therefore, it is not advisable to
initiate any Tele Aid call unless the Tele Aid
system is activated and operational. To adjust the speaker volume during a Tele
Aid call do the following:
X
Press button W or X on the
multifunction steering wheel.
or
X Use the adjustment button on your

Warning!
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide (CO),

You may only use the MOExtended system in
conjunction with the tire pressure loss
warning system (
Y page 231) or the
Advanced TPMS (Y page 232).
i Vehicles with MOExtended system are
not factory-equipped with a TIREFIT kit.
When
retrofitting with tires that do not have
run-flat characteristics, e.g. winter tires,
you should also equip your vehicle with a
TIREFIT kit. TIREFIT kits are available at any
authorized Mercedes-Benz Center.
For information on driving in case of pressure
loss in one or more tires (emergency mode),
see the “Practical Hints” section
(Y page 330). Tire care and maintenance
G
Warning!
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn,

old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
Check the tire inflation pressure at least once
a month. For more information on checking
tire inflation pressure, see “Recommended
tire inflation pressure” ( Y page 228).
Tire inspection Every time you check the tire inflation
pressure, you should also inspect your tires
for the following:
R
excessive treadwear ( Y page 241)
R cord or fabric showing through the tire’s
rubber
R bumps,

bulges, cuts, cracks or splits in the
tread or side of the tire
Replace the tire if you find any of the above
conditions. Make sure you also inspect the spare tire
periodically

for condition and inflation. Spare
tires will age and become worn over time even
if never used, and thus should be inspected
and replaced when necessary.
Life of tire G
Warning!
Tires and spare tire should be replaced after
6 years, regardless of the remaining tread.
The service life of a tire is dependent upon
varying factors including but not limited to:
R Driving style
R Tire inflation pressure
R Distance driven
Tread depth G
Warning!
Although the applicable federal motor vehicle
safety laws consider a tire to be worn when
the

treadwear indicators (TWI) become visible
at approximately 1
/ 16 in (1.6 mm), we
recommend that you do not allow your tires
to wear down to that level. As tread depth
approaches 1
/ 8 in (3 mm), the adhesion
properties on a wet road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Do not allow your tires to wear down too far.
Adhesion properties on wet roads are sharply
reduced at tread depths of less than 1
/ 8 in
(3 mm).
Treadwear indicators (TWI) are required by
law. These indicators are located in six places
on the tread circumference and become
visible at a tread depth of approximately
1 / 16 in (1.6 mm), at which point the tire is
considered worn and should be replaced.
The recommended minimum tire tread depth
for summer tires is 1
/ 8 in (3 mm). The Tires and wheels

recommended minimum tire tread depth for
winter tires is
1
/ 6 in (4 mm). Treadwear indicator
: appears as a solid
band across the tread.
Storing tires !
Keep unmounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease
and fuels.
Cleaning tires !
Never use a round nozzle to power wash
tires. The intense jet of water can result in
damage to the tire.
Always replace a damaged tire. Uniform Tire Quality Grading
Standards
The Uniform Tire Quality Grading is a U.S.
Government requirement designed to give
drivers consistent and reliable information regarding tire performance. Tire
manufacturers are required to grade tires
based on three performance factors:
treadwear
:, traction ;, and temperature
resistance =. Although not a Government of
Canada requirement, all tires made for sale in
North America have these grades branded on
the sidewall.
i For illustration purposes only. Actual data
on tires are specific to each vehicle and
may vary from data shown in above
illustration.
Quality grades can be found, where
applicable, on the tire sidewall between tread
shoulder and maximum section width. For
example: Treadwear Traction Temperature
200 AA A
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
U.S. Government test course. For example, a
tire graded 150 would wear one and one-half
(1
1
/ 2) times as well on the government
course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction G
Warning!
The traction grade assigned to this tire is
based on straight-ahead braking traction 242
