Use only snow chains that are tested and recommended
by Mercedes-Benz. Your authorized Mercedes-Benz
Center will be glad to advise you on this subject.
Chains should only be used on the rear wheels. Follow
the manufacturer’s mounting instructions.
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.
When driving with snow chains, press the ESP control
switch to OFF, refer to page 218.
Important!
Use of snow chains is not permissible with tire sizes
225 / 45 R17 and 245 / 40 R17.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
selector lever to position “N”. Try to keep the vehicle
under control by corrective steering action.
Road salts and chemicals can adversely affect braking
efficiency. Increased pedal force may become necessary
to produce the normal brake effect. We therefore
recommend depressing the brake pedal periodically
when traveling at length on salt-strewn roads. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.
Exceeding the maximum speed for which tires are
rated can lead to sudden tire failure causing loss of
vehicle control and resulting in personal injury
and possible death.

Malfunction and warning messages for the following
systems will be displayed immediately in the
multifunction display.
These messages can be cleared from the instrument
cluster by:
•using the J button on the instrument cluster, or
•pressing buttonj, k, è or ÿ on the
multifunction steering wheel.
They are then stored in the malfunction message
memory. See page 100.Notes:
Certain malfunction and warning messages are
accompanied by an audible signal.
Malfunction and warning messages in red are always
accompanied by an audible signal.
Temporary messages such as “SWITCH OFF LIGHTS”
will not be stored in the malfunction message memory.
Wa r n i n g !
All messages contain important information which
should be taken note of and, where malfunction
indicated, addressed as soon as possible at an
authorized Mercedes-Benz Center.Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz Limited
Warranty, or result in property damage or personal
injury.

BATTERY/ALTERNATORThis message indicates a malfunction which must be
repaired immediately.
It may indicate that the poly-V-belt has broken. Should
this condition occur, the poly-V-belt must be replaced
before continuing to operate the vehicle. Otherwise, the
engine will overheat due to an inoperative water pump
which may result in damage to the engine.
Do not continue to drive the vehicle with this message
displayed.
Doing so could result in serious engine damage that is
not covered by the Mercedes-Benz Limited Warranty.

Notes:
Before storing the jack, the jack arm must be lowered
almost to the base of the jack.
For proper storage of vehicle jack see page 257.Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approx. 1.5 psi (0.1 bar) per
18
°F (10
°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approx. +68
°F (+20
°C) and
ambient temperature = approx. +32
°F (0
°C) then the
adjusted air pressure = specified air pressure +3 psi
(+0.2 bar).
Wa r n i n g !
CLK 320 with Sport Package:
The dimensions of the spare wheel are different
from those of the road wheels. As a result, the
vehicle handling characteristics change when
driving with a spare wheel mounted.
CLK 430:
The dimensions of the spare wheel are different
from those of the road wheels for the rear axle. As a
result, the vehicle handling characteristics change
when driving with a spare wheel mounted on the
rear axle.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quick as
possible.When using the spare wheel, do not exceed vehicle
speed of 50 mph (80 km/h).

cluster displayPractical hintsCar care Index The pressures listed for light loads are minimum values
offering high driving comfort.
Increased inflation pressures listed for heavier loads
may also be used for light loads. These higher pressures
produce favorable handling characteristics. The ride of
the vehicle, however, will be somewhat harder. Never
exceed the max. values or inflate tires below the min.
values listed in the fuel filler flap.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.
Wa r n i n g !Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated tires can
result in sudden deflation (blowout) because they
are more likely to become punctured 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.

Cleaning and care of the 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 extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. 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; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or 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 the start of
corrosion.
In doing so, do not neglect the underside 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 reundercoated.
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 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 your authorized Mercedes-Benz Center.
Wa r n i n g !
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.Never use fluids or solvents that are not designed
for cleaning your vehicle.
