Changing wheelsMove vehicle to a level area which is a safe distance
from the roadway.
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine.
3. Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axle. On an level road, place one chock in front of
and one behind the wheel that is diagonally
opposite to the wheel being changed.
Wa r n i n g !
The jack is designed exclusively for jacking up the
vehicle at the jack tubes built into either side of the
vehicle. To help avoid personal injury, use the jack
only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from the area
under the lifted vehicle. Always firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parking brake while the vehicle is
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.

vehicle tool kit and assemble. Using the wrench,
loosen but do not yet remove the wheel bolts.5. Remove the protective cover from the jack support
tube opening by inserting the screwdriver (supplied
in the tool kit) in the opening and prying it out.
The tube openings are located directly behind the
front wheel housings and in front of the rear wheel

6. Insert jack arm fully into the tube hole up to the
stop. Place jack on firm ground. Position the jack so
that it is always vertical (plumb-line) as seen from
the side (see arrow), even if the vehicle is parked on
an incline.
7. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.8. Unscrew upper-most wheel bolt and install
alignment bolt (1) supplied in the tool kit. Remove
the remaining bolts. Keep bolt threads protected
from dirt and sand.
9. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.

Install spare wheel on wheel hub. Insert wheel bolts
and tighten them slightly.
To avoid paint damage, place wheel flat against hub
and hold it there while installing first wheel bolt.
Unscrew the alignment bolt to install the last wheel
bolt.11. Lower vehicle. Remove jack and insert jack tube
cover.

12. Using the wrench, tighten the five bolts evenly,
following the sequence illustrated, until all bolts are
tight.
Observe a tightening torq ue of 110 ft.lb. (150 Nm).
13. Ensure proper tire pressure.
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 335.

Wa r n i n g !
Always replace wheel bolts that are damaged or
rusted.Never apply oil or grease to wheel bolts.Damaged wheel hub threads should be repaired
immediately.Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.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.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quick as
possible.CL 55 AMG and 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 mounted spare wheel.

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..

under the right-hand wheel well cover panel.
For battery removal or installation, or jump starting the
vehicle, first lift the trunk f loor, then turn lock (1)

Important!
Battery replacement information:The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in starter switch position 0. The
battery, its filler caps, the vent tube and the opposite
plug must always be securely installed when the vehicle
is in operation.
