167 Operation
Driving instructions
Winter driving instructions
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,
move gear selector lever to positionN or
declutch in case of manual transmission.
Try to keep the vehicle under control by
corrective steering action.Road salts and chemicals can adversely af-
fect 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 efficien-
cy should be tested as soon as possible af-
ter driving is resumed.
For more information, see “Winter driving”
(
page 188).
iFor information on driving with snow
chains, see “Snow chains”
(page 189).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
Warning
G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
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 ve-
hicle not facing the wind.Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.

192 OperationVehicle care
Vehicle careCleaning and care of vehicle
In operation, your vehicle is subjected to
varying external influences which, if gone
unchecked, can attack the paintwork as
well as the underbody and cause lasting
damage.Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:


Air pollution


Road salt


Tar


Gravel and stone chipping
To avoid paint damage, you should imme-
diately 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 the start of 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 ap-
plied 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 de-
signed for cleaning your vehicle.

Raising retractable hardtop manually
If the retractable hardtop cannot be closed
automatically, make certain that all points
listed under the “Retractable hardtop” sec-
tion (
page 130) were observed.
If the automatic operation still does not
function properly, you can close the re-
tractable hardtop manually.
This procedure should be performed with
great care by two persons.

Open doors or lower windows
(page 128).

Set parking brake (
page 47).

Remove key from steering lock
(page 29).

Open trunk lid (
page 78).

Remove CD changer (
page 122).

Open the right side trim panel in the
trunk. Remove cover, if necessary.
!Manually closing the retractable hard-
top is a complicated and technically de-
manding procedure. Close the
retractable hardtop manually in emer-
gency cases only. Otherwise, visit an
authorized Mercedes-Benz Center.
Warning!
G


It is important that a second person
helps you. Otherwise, you could become
trapped or injured.


Remove any wristwatches or jewelry
such as rings or bracelets. Otherwise,
they could get caught in the vehicle
mechanism, causing personal injury to
yourself or damage to the vehicle.


Always use the grips provided. Other-
wise you could injure yourself.
iIf your CD changer holder does not
have the fasteners 1 as shown under
“Installing and removing the CD chang-
er*” (
page 122), your vehicle may be
equipped with a non-factory installed
CD changer holder. The holder then
does not need to be removed as there
should be enough room between the
CD changer holder and the right side
trim panel in the trunk to remove the
cover and gain access to the screw for
hydraulic pump should you need to
raise the retractable hardtop manually.
