The Tele Aid system consists of three
types of response:


automatic and manual emergency


roadside assistance and


information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To

To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.Shortly after the completion of your
Tele Aid acquaintance call, you will receive
a user ID and password via first call mail.
By visiting www.mbusa.com and selecting
“Tele Aid” (USA only), you will have access
to account information, remote door un-
lock, Info Services profile and more.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using the
SOS button. Failure to complete either
of these steps will result in a system
that is not activated. If the system is
not activated, the indicator lamp in the
SOS button stays on after turning
SmartKey in starter switch to
position2 or pressing KEYLESS-GO*
start/stop button twice to position2
(page 33). The message

iThe SOS button is located above the in-
terior rear view mirror.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest cov-
er.!The Tele Aid system utilizes the cellular
network for communication and the

lites for vehicle location. If either of
these signals is unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.

270 OperationDriving instructions
TiresTread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1⁄16 in (1.6 mm), at which point the
tire is considered worn and should be re-
placed.
The tread wear indicator appears as a solid
band across the tread.
Warning!
G
To reduce the risk of personal injury as a re-
sult of inadvertent vehicle movement, be-
fore turning off the engine and leaving the
vehicle always:

Keep right foot firmly on brake pedal.


Firmly depress parking brake pedal.


Move the gear selector lever to
positionP.


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the SmartKey to starter switch
position0 and remove, or press
KEYLESS-GO* start/stop button (vehi-
cles with KEYLESS-GO*).


Take the SmartKey or the SmartKey with
KEYLESS-GO* with you and lock vehicle
when leaving.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.
Warning!
G
Although the applicable federal motor vehi-
cle safety laws consider a tire to be worn
when the tread wear indicators (TWI) be-
come visible at approximately
1/16in
(1.6 mm), we recommend that you do not al-
low your tires to wear down to that level. As
tread depth approaches
1/8in (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.

Vehicle care
We have selected car-care products and
compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain Mercedes-Benz approved
car-care products at your authorized
Mercedes-Benz Center.
Scratches, corrosive deposits, corrosion or
damage due to negligent or incorrect care
cannot always be removed or repaired with
the car-care products recommended here.
In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references
to Mercedes-Benz approved car-care prod-
ucts.
Additional information can be found in the
booklet “Vehicle Care Guide“.Power washer
When using a power washer for cleaning
the vehicle, always observe the manufac-
turer’s operating instructions.Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.
Paintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not “bead up”, normally
every three to five months, depending on
climate and washing detergent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface
shows signs of embedded dirt (i.e. loss of
gloss).
Do not apply any of these products or wax
if your vehicle is parked in the sun or if the
hood is still hot.
Use the appropriate MB-Touch-Up Stick
for quick and provisional repairs of minor
paint damage (i.e. chips from stones, vehi-
cle doors, etc.).
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approx. 3 ft (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked. !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.
Always keep the jet of water moving
across the surface. Do not aim directly
at electrical parts, electrical connec-
tors, seals, or other rubber parts.

300 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax, should be applied to the en-
gine compartment after every engine
cleaning. Before applying, all control link-
age bushings and joints should be lubricat-
ed. The poly-V-belt and all pulleys should
be protected from any wax. Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Only use a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently.
Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and only use a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a SmartKey with
KEYLESS-GO* is in close proximity, i.e.
within approx. 3 ft (approx. 1 m), the
vehicle could be inadvertently locked
or unlocked.
