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.

cluster displayPractical hints Car care Index Tempera t u re
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger vehicle tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Wa r n i n g !
The temperature grade for this tire is established
for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause excessive heat build up
and possible tire failure.
