To ensure proper functioning of the tire inflation
pressure monitor, the tire inflation pressure should be
checked and corrected according to the label affixed
inside the fuel filler flap. For a detailed description,
refer to page 345.
The message “TIRE PRESS. CONTROL – REACTIVATE”
appears if the tire inflation pressure shows an increase
of 4.4 psi (0.3 bar) or more. Reactivate the tire inflation
pressure monitor.
The tire inflation pressure monitor only functions on
wheels equipped with the proper electronic sensors.
Inquire at your authorized Mercedes-Benz Center about
retrofitting other than original Mercedes-Benz wheels
with electronic sensors.Transporting a deflated road wheel in the vehicle, e.g.
after having a flat, the tire inflation pressure monitor
should only be activated once the flat tire and rim are
removed from the vehicle. Otherwise the monitor
displays the message “TIRE PRESS. CONTROL –
CURRENTLY INACTIVE”.
To prevent possible damage to the electronic sensors,
have tire changes only performed at an authorized
Mercedes-Benz Center.
For malfunction and warning messages, see page 312.

Drive sensibly – save fuel
Fuel consumption, to a great extent, depends on driving
habits and operating conditions.
To save fuel you should:
•keep tires at the recommended inflation pressures.
•remove unnecessary loads,
•remove roof rack when not in use,
•allow engine to warm up under low load use,
•avoid frequent acceleration and deceleration,
•have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold
weather, in stop-and-go traffic, on short trips and in hilly
country.Drinking and driving
Wa r n i n g !
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.

3 For tire inflation pressure monitor, see page 150.4 Tire pressure in one or more tires is low. Check and correct tire
pressure, see page 345.
5 The tire pressure monitor cannot be activated with the engine
running. Turn off the engine and repeat activation, see page 151.
6 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 345.
The tire inflation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 151.
7 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
8 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire will cause excessive heat build-up and possibly
a fire.

Rotating wheels
The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim f langes must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
inside of fuel filler flap and also page 345.Spare wheel
Spare wheel CL 500 and CL 600
(except Sport Package)
Important!
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle, and is fully functional.
However, that spare wheel rim is weight optimized and
has a limited service life of 12 000 miles (20 000 km)
use before a standard wheel rim must replace it.
In the case of a flat tire, you may temporarily use the
spare wheel.
Do not operate vehicle with more than one spare wheel
mounted.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km)
(aggregate of all uses) may cause wheel rim failure
leading to an accident and possible injuries.

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).Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
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 underinf lated 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.Battery
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.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.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc..
