Warning!
G
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when stowing objects in the vehicle. Put lug-
g a g e o r c a r g o i n t h e t r u n k i f p o s s i b l e . D o n o t
pile luggage or cargo higher than the seat
backs. Do not place anything on the shelf
below the rear window.
Luggage nets cannot secure hard or heavy
objects.
Keep compartment lids closed. This will help
to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.
iPrior to closing the glove box, close the
compartment for glasses first.

Upgrade signals
The Tele Aid system processes calls using
the following priority:

Automatic emergency – First priority


Manual emergency – Second priority


Roadside assistance – Third priority


Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade
(alternating) tone will be heard, and the
appropriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to
retransmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retrans-
mission is completed. Once a call is
concluded, a beep will be heard and the
respective indicator lamp will stop flash-
ing. The COMAND* system operation will
resume.
!If the indicator lamp continues to flash
or the system does not reset, contact
the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada), or
Mercedes-Benz Customer Assistance
at 1-800-FOR-MERCedes
(1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100
in Canada.iThe indicator lamp in the respective
button flashes until the call is con-
cluded. Calls can only be terminated by
a Response Center or Customer Assis-
tance Center representative except
Roadside Assistance and Information
calls, which can also be terminated by
pressing buttonì on the multifunc-
tion steering wheel.
iWhen a Tele Aid call has been initiated,
the audio system or the COMAND* sys-
tem audio is muted and the selected
mode (radio, tape or CD) pauses. The
optional cellular phone (if installed)
switches off. If you must use this
phone, the vehicle must be parked. Dis-
connect the coiled cord and place the
call. The COMAND* navigation system
(if engaged) will continue to run. The
display in the instrument cluster is
available for use, and spoken com-
mands are only available by pressing
the RPT button on the COMAND* unit.
A pop-up window will appear in the
COMAND* display to indicate that a
Tele Aid call is in progress.

245 Operation
Driving instructions
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed.
For more information, see “Winter driving”
(
page 263).
Standing water
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Warning!
G
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monox-
ide (CO) gases may enter vehicle interior re-
sulting in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the
vehicle not facing the windWarning!
G
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the
road surface is free of ice.
!Do not drive through flooded areas or
water of unknown depth. Before driving
through water, determine its depth.
Never accelerate before driving into
water. The bow wave could force water
into the engine and auxiliary equip-
ment, thus damaging them.
If you must drive through standing wa-
ter, drive slowly to prevent water from
entering the passenger compartment
or the engine compartment. Water in
these areas could cause damage to
electrical components or wiring of the
engine or transmission, or could result
in water being ingested by the engine
through the air intake causing severe
internal engine damage. Any such
damage is not covered by the
Mercedes-Benz Limited Warranty.

248 OperationDriving instructions
Coolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant
temperature may rise close to
approximately 248°F (120°C).
The engine should not be operated with
the coolant temperature over 248°F
(120°C). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause
unconsciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Warning!
G


Driving when your engine is badly
overheated can cause some fluids,
which may have leaked into the engine
compartment, to catch fire. You could
be seriously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

Vehicle care
Cleaning and care of the vehicle
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the under-
body and cause lasting damage.Such damage is caused not only by
extreme and varying climatic conditions,
but also by:


Air pollution


Road salt


Tar


Gravel and stone chipping
To avoid paint damage, you should
immediately remove:


Grease and oil


Fuel


Coolant


Brake fluid


Bird droppings


Insects


Tree resins, etc.
Frequent washing reduces and/or elimi-
nates the aggressiveness and potency of
the above adverse influences.More frequent washings are necessary to
deal with unfavorable conditions:


near the ocean


in industrial areas (smoke, exhaust
emissions)


during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
A n y d a m a g e s h o u l d b e r e p a i r e d a s s o o n a s
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others
applied later.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
