2010 MERCEDES-BENZ CLS63AMG air condition

Observe the following guidelines when using
snow chains:
R
Use
of snow chains is not permissible with
all wheel/tire combinations ( Y page 291).
R Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
! If snow chains are mounted to the front
wheels, they may scrape against the body
or axle components. The tires or the vehicle
could be damaged as a result.
R Only use snow chains that are approved by
Mercedes-Benz. Any authorized Mercedes-
Benz Center will be glad to advise you on
this subject.
R Use of snow chains may be prohibited
depending on location. Always check local
and state laws before installing snow
chains.
R Do not use snow chains on the spare wheel.
i When driving with snow chains, you may
wish to switch off the ESP ®
(Y page 59)
before setting the vehicle in motion. This
will improve the vehicle’s traction. Winter driving instructions
G
Warning!
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 monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To

assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind. G
Warning!
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. The road may still be icy,
especially in wooded areas or on bridges. G
Warning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result

in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
The most important rule for slippery or icy
roads is to drive sensibly and to avoid abrupt
acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, shift
the automatic transmission to neutral
position N. Try to keep the vehicle under
control by corrective steering action.
i For information on driving with snow
chains, see “Snow chains” ( Y page 208).
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal brake 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. G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. Winter driving

X
Reduce vehicle speed.
X Avoid track grooves in the road.
X Apply brakes cautiously. Standing water
! Do not drive through flooded areas.
Before
driving through water, determine its
depth.
If you must drive through standing water,
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. Driving abroad
If
you plan to drive the vehicle outside the U.S.
or Canada, you should request dealer
network information for your destination from
any authorized Mercedes-Benz Center. Control and operation of radio

Safety notes G
Warning!
Please do not forget that your primary
responsibility
is to drive the vehicle. A driver’s
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, we recommend that
you pull over to a safe location and stop
before placing or taking a telephone call.
If you choose to use the telephone 12
while
driving, please use the hands-free device and only use the telephone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the COMAND
12
(Cockpit
Management and Data System) if road,
weather and traffic conditions permit.
Otherwise, you may not be able to observe
traffic

conditions and could endanger yourself
and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second. Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when

maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet. G
Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible 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
12 Observe all legal requirements. Driving instructions

vehicle’s doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always
lock away cleaning products and keep
them out of reach of children.
! When cleaning the vehicle, do not use
scouring agents. Never apply strong force
and only use a soft, wet cloth or sponge.
Otherwise you may scratch or damage the
surface to be cleaned.
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 vehicle
underbody and cause lasting damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also by:
R Air pollution
R Road salt
R Tar
R Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
R Grease and oil
R Fuel
R Coolant
R Brake fluid
R Bird droppings
R Insects
R Tree resins etc.
Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above
adverse influences. More frequent washings are necessary to
deal with unfavorable conditions:
R
near the ocean
R in industrial areas (smoke, exhaust
emissions)
R during winter operation
You should check your vehicle from time to
time
for stone chipping or other damage. Any
damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody of
the vehicle. A prerequisite for a thorough
check is a washing of the underbody followed
by a thorough inspection. Damaged areas
need to be re-undercoated.
Your vehicle has been treated at the factory
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.
We have selected vehicle-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 vehicle-care
products at an authorized Mercedes-Benz
Center.
Scratches, corrosive deposits, corrosion or
damage due to negligent or incorrect care
cannot always be removed or repaired with
the vehicle-care products recommended
here. In such cases it is best to seek aid at an
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 vehicle-care
products. 216
