Treadwear indicators
Narrow bands, sometimes called “wear bars”
that
show across the tread of a tire when only
1 / 16 in (1.6 mm) of tread remains.
Uniform Tire Quality Grading Standards A tire information system that provides
consumers with ratings for a tire’s traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using U.S.
government testing procedures. The ratings
are molded into the sidewall of the tire.
Vehicle maximum load on the tire
Load on an individual tire that is determined
by distributing to each axle its share of the
maximum
loaded vehicle weight and dividing
it by two. Winter driving
General information
Have
your vehicle winterized at an authorized
Mercedes-Benz Center. Winter tires
G
Warning!
Winter tires with a tread depth of less than
1 / 6 in (4 mm) must be replaced. They are no
longer suitable for winter operation. G
Warning!
If you use your spare wheel when winter tires
are fitted on the other wheels, be aware that
the
difference in tire characteristics may very
well impair turning stability and that overall
driving stability may be reduced. Adapt your
driving style accordingly.
Have the spare wheel replaced by a regular
road wheel with a winter tire at the nearest
authorized Mercedes-Benz Center. Always use winter tires at temperatures
below 45‡ (7†) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflakeimarking on the tire sidewall.
These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the
only way to achieve the maximum
effectiveness of your vehicle’s driving safety
systems such as the ABS and the ESP
®
in
winter operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the “Technical data”
section ( Y page 291).
Always
observe the speed rating of the winter
tires installed on your vehicle. Snow chains
! When driving with snow chains, always
select the raised level of the vehicle level
control. Other settings may result in
damage to your vehicle.
! Some tire sizes do not leave adequate
clearance for snow chains. To help avoid
serious damage to your vehicle or tires,
make sure the use of snow chains is
permissible as specified in the “Technical
data” section of this Operator’s Manual.
Snow chains should only be driven on snow-
covered roads at speeds not to exceed
30 mph (50 km/h)
. Remove chains as soon
as possible when driving on roads without
snow. 208

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

Driving instructions
Drive sensibly – save fuel
To save fuel you should:
R Keep tires at the recommended inflation
pressures.
R Remove unnecessary loads.
R Remove roof rack when not in use.
R Allow engine to warm up under low load
use.
R Avoid frequent acceleration and
deceleration.
R Have all maintenance work performed at
the intervals specified in the Maintenance
Booklet and as required by the
Maintenance system. Contact an
authorized Mercedes-Benz Center.
Fuel
consumption is also increased by driving
in cold weather, in stop-and-go traffic, on
short trips and in mountainous areas. Drinking and driving
G
Warning!
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident
are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs. Pedals
G
Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Power assistance
G
Warning!
There is no power assistance for the steering
and
the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion. Brakes
Downhill grades !
When driving down long and steep
grades, relieve the load on the brakes by
shifting into a lower gear to use the
engine’s
braking power. This helps prevent
overheating of the brakes and reduces
wear.
When using the engine’s braking power, a
drive wheel may not spin for an extended
period of time, e.g. on slippery road
surfaces. This may cause serious damage
to the drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Continuous or hard braking G
Warning!
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads. 210

dynamometer or when the vehicle is being
towed with the front axle raised.
Active braking action through the ESP
®
may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
If your brake system is only subjected to
moderate loads, you should occasionally test
the effectiveness of the brakes by applying
above-normal braking pressure at higher
speeds. This will also enhance the grip of the
brake pads. G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Refer to the description of the Brake Assist
System (BAS) ( Y page 59).
High-performance brake system The high-performance brake system is only
available on CLS 63 AMG.
G
Warning!
New vehicle brake pads and discs, and
replacement brake pads and discs may take
several hundred miles of driving until they
provide
optimum braking efficiency. Until that
time, you may need to use increased brake
pedal pressure while braking. Please be aware
of this and adjust your driving and braking
accordingly during this break-in period.
Excessive high-demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition
messages in the multifunction display.
Especially for high performance driving, it is
important to maintain and have the brake
system checked regularly.
The high-performance brake system is
designed to operate under the extremely high
operating demands required to accommodate the performance capabilities
of the vehicle.
The brakes may produce a squeaking-type
noise depending on the
R
vehicle speed
R brake force applied
R ambient conditions, e.g. temperature and
humidity
As with any brake system, the wear of
individual
brake system components such as
brake pads or disks strongly depends on your
driving style and the conditions under which
you operate the vehicle. Thus, a driving style
calling for high-demand braking will cause
your vehicle’s brakes to wear more quickly. Driving off
Warm up the engine smoothly. Do not place
full load on the engine until the operating
temperature has been reached.
! When
driving off on a slippery surface, do
not allow a drive wheel to spin for an
extended period with the ESP ®
switched
off. Doing so may cause serious damage to
the drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
! Simultaneously depressing the
accelerator pedal and applying the brakes
reduces engine performance and causes
premature brake and drivetrain wear which
is not covered by the Mercedes-Benz
Limited Warranty. Hydroplaning
Depending
on the depth of the water layer on
the road, hydroplaning may occur, even at low
speeds and with new tires. In heavy rain or
when conditions indicate possible
hydroplaning: 212

Power washer
!
Follow the instructions provided by the
power washer manufacturer on
maintaining
a distance between the vehicle
and the nozzle of the power washer.
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 connectors, seals, or other
rubber parts.
i Vehicles with KEYLESS-GO:
If a door handle is hit by a strong jet of
water, and a SmartKey is within
approximately 3 ft (1 m) of the vehicle, it
could be inadvertently locked or unlocked.
Tar stains Quickly remove tar stains before they dry and
become more difficult to remove. A tar
remover is recommended.
Paintwork, painted body components
!
Affixing stickers, magnets, adhesive tape
or similar materials to painted body
components may damage the paintwork.
Mercedes-Benz approved Paint Care should
be applied when water drops on the paint
surface do not “bead up”. This should
normally be done every 3 to 5 months,
depending on the 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.
X Use the appropriate MB-Touch-Up Stick for
quick
and provisional repairs of minor paint damage (i.e. chips from stones, vehicle
doors, etc.).
Vehicles with mat paint
Your vehicle is painted with mat clear-coat
paint. Observe the following notes to avoid
paint
damage caused by improper treatment.
i Only use insect remover and car shampoo
approved by Mercedes-Benz.
! Do not polish the vehicle. Polishing will
brighten the paintwork.
Do not use paintwork cleaning agents,
abrasives, polishing compounds, or wax for
paintwork care. Such products are
intended for use on high-polish surfaces.
Using such products on mat paint causes
severe damage, such as bright, spotted
areas on the respective surface.
Have paintwork repairs performed at an
authorized Mercedes-Benz Center.
Have stone chipping repairs as soon as
possible.
Remove the following immediately if possible.
Do not apply strong force.
R Soak insect remains with insect remover
and rinse them of with water afterwards.
Use a soft bristle toothbrush for remains
that have not come off.
R Soak bird droppings with water and rinse
them of with water afterwards. Use a soft
bristle toothbrush for remains that have not
come off.
R Remove tree resins, grease, oil, and
gasoline with silicone remover.
R Dab off wax with silicone remover.
R Dab off tar splashes or tar stains with tar
remover.
Engine cleaning Prior to cleaning the engine compartment,
make sure to protect electrical components
and connectors from contact with water and
cleaning agents. Vehicle care

Warning!
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. Symbol messages
