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 297).
Always
observe the speed rating of the winter
tires installed on your vehicle. Snow chains
! 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.
Observe the following guidelines when using
snow chains:
R Use of snow chains is not permissible with
all wheel/tire combinations ( Y page 297).
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 49)
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 220

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.
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.
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.).
Engine cleaning Prior to cleaning the engine compartment,
make sure to protect electrical components
and connectors from contact with water and
cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax should be applied to the
engine compartment after every engine
cleaning. Before applying, all control linkage
bushings
and joints should be lubricated. The
poly-V-belt and all pulleys should be
protected from any wax.
Vehicle washing In the winter, thoroughly remove all traces of
road salt as soon as possible.
When
washing the vehicle underbody, do not
forget to clean the inner sides of the wheels.
Hand-wash
X Do not use hot water or wash your vehicle
in direct sunlight.
X Only use a soft, wet cloth or sponge to
clean the vehicle.
X Only use a mild vehicle wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
X Thoroughly spray the vehicle with a
diffused jet of water.
X Do not spray directly towards the
ventilation intake.
X Use plenty of water and rinse the sponge
and chamois frequently.
X Rinse with clean water and dry with a
chamois thoroughly. 228

arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
! To clean the window interior, do not use
a dry cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the
inside of the windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
Rear window cleaning
Clean the rear window with the hardtop fully
raised and closed. G
Warning!
Do not clean the rear window with the hardtop
in a position other than the fully raised and
closed position. Otherwise, the hardtop may
move unexpectedly which may result in
personal injury to you or others. X
Use a soft, clean cloth and a mild window
cleaning solution on all outside and inside
glass surfaces.
An automotive glass cleaner is
recommended.
Light alloy wheels If possible, clean wheels once a week.
X
Use Mercedes-Benz approved Wheel Care,
a soft bristle brush and a strong spray of
water for cleaning the light alloy wheels.
! Only use acid-free cleaning materials.
Acid may cause corrosion or damage the
clear coat.
! The vehicle should not be parked for an
extended period of time immediately after
it
has been cleaned. This applies especially
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim cleaners
can lead to increased corrosion of the
brake disks and brake pads. Non-approved
wheel cleaners may also damage the wheel
paint if the vehicle is not driven after
cleaning.
Therefore, the vehicle’s brake system
should always be warmed-up before it is
parked after cleaning. Drive your vehicle for
several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved
Tire Care and Mercedes-Benz approved
Wheel Care products, take care not to
spray them on the brake disks.
Plastic and rubber parts X
Use a gentle dishwashing detergent or mild
detergent
for delicate fabrics as a washing
solution.
X Wipe with a cloth moistened in a lukewarm
solution.
The
surface may temporarily change color.
If this is the case, wait for it to dry. 230

Fabric Care for cleaning the carpets.
Headliner X
Use a soft bristle brush or a dry-shampoo
cleaner in case of excessive dirt. Seat belts X
Only use clear, lukewarm water and soap.
! The seat belts must not be treated with
chemical cleaning agents. Do not dry the
seat belts at temperatures above
176‡
(80†) or in direct sunlight. G
Warning!
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Upholstery Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause the
upholstery to become permanently
discolored. By lining the seats with a proper
intermediate
cover, contact-discoloration will
be prevented. G
Warning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the head-thorax air bags. Contact an
authorized Mercedes-Benz Center for
availability.

natural product and is therefore subject to a
natural aging process. Leather upholstery
may also react to certain ambient influences
such
as high humidity or high temperature by
showing wrinkles for example.
X Wipe leather upholstery with a damp cloth
and
dry thoroughly or clean with Mercedes-
Benz approved Leather Care.
