2005 MERCEDES-BENZ C320 tires

291 Operation
Winter driving
Block heater (Canada only)
The engine is equipped with a block
heater.
The electrical cable may be installed at an
authorized Mercedes-Benz Center.
Snow chains
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.
Please observe the following guidelines
when using snow chains:

Use of snow chains is not permissible
with all wheel/tire combinations.


Snow chains should only be used on
the rear wheels. Follow the manufac-
turer's mounting instructions.


Only use snow chains that are
approved by Mercedes-Benz. Your
authorized Mercedes-Benz Center will
be glad to advise you on this subject.


Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 79) before setting the vehicle
in motion. This will improve the
vehicle‘s traction.
!Even on vehicles with all-wheel-drive
use snow chains on rear tires only.
Use of snow chains is not permissible
with tire sizes:

296 OperationVehicle careWe have selected car-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
car-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 car-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 car-care
products.
Additional information can be found in the
booklet “Vehicle Care Guide”.Power washer
When using a power washer for cleaning
the vehicle, always observe the manu-
facturer’s operating instructions.Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.
Paintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not “bead up”, normally
every three to five months, depending on
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.
Use the appropriate MB-Touch-Up Stick
for quick and provisional repairs of minor
paint damage (i.e. chips from stones,
vehicle doors, etc.).
!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 connec-
tors, seals, or other rubber parts.

334 Practical hintsWhere will I find ...?
In the case of a flat tire, you may
temporarily use the Minispare wheel when
observing the following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km/h).


Drive to the nearest tire repair facility
to have the flat tire repaired or
replaced as appropriate.


Do not operate vehicle with more than
one Minispare wheel mounted.
For more information, see “Rims and Tires”
(
page 380).
Collapsible tire (C 55 AMG only)
The collapsible tire is located in the
storage compartment underneath the
trunk floor.
Removing the collapsible tire
Lift up trunk floor cover and engage
trunk floor handle in upper edge of
trunk.

2Vehicle tool kit (under collapsible tire)
3Retaining screw
!To prevent damage, always disengage
trunk floor handle from upper edge of
trunk and lower trunk floor before
closing the trunk lid.Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted.
The Minispare wheel should only be used
temporarily, and should be replaced with a
regular road wheel as quickly as possible.

336 Practical hintsWhere will I find ...?In the case of a flat tire, you may
temporarily use the collapsible tire when
observing the following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km/h).


Drive to the nearest tire repair facility
to have the flat tire repaired or

Spare wheel bolts
1Wheel bolt for light alloy rims
2Wheel bolt for Minispare wheel,
collapsible tire, or other steel rims
(located in trunk with spare wheel)
!Wheel bolts2 must be used when
mounting the Minispare wheel,
collapsible tire, or other steel rims. The
use of any wheel bolts other than wheel
bolts2 for the Minispare wheel,
collapsible tire, or other steel rims will
physically damage the vehicle’s
brakes. Warning!
G
Make sure to use the original length wheel
bolts when remounting the original wheel
after it has been repaired.

358 Practical hintsFlat tire
Screw air hose 4 onto the collapsible
tire valve.

Insert electrical plug 3 into vehicle
cigarette lighter socket.

Turn the SmartKey in the starter switch
to position1.

Press I on electric air pump switch 2.
The electric air pump should now
switch on and inflate the collapsible
tire.

Inflate the tire to approximately 36 psi
(2.5 bar).
This takes about five minutes for the
collapsible tire. Air hose 4 and union
nut5 can become hot duration infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

Press 0 on electric air pump switch 2.

Turn the SmartKey in the starter switch
to position0.

If the tire pressure is above 36 psi
(2.5 bar), release excess tire pressure
using the vent screw.

Detach the electric air pump.

Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the trunk.
!Do not operate the electric air pump
longer than six minutes without inter-
ruption. Otherwise it may overheat.
You may operate the electric air pump
again after it has cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.

Consumer information

380 Technical dataRims and TiresOnly use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as

poor handling characteristics


increased noise


increased fuel consumption
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and
different tire deformation characteris-
tics that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the
vehicle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A tire inflation
pressure table is located on the fuel
filler flap of the vehicle. The tire pres-
sure should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.
