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.

Seat belts
The webbing must not be treated with chemical 
cleaning agents. Use only clear, lukewarm water and 
soap. Do not dry the webbing at temperatures above 
176°F (80°C) or in direct sunlight.
Headliner and shelf below rear window
Clean with soft bristle brush, or use a dry-shampoo 
cleaner in case of excessive dirt.Leather upholstery
Using aftermarket seat covers or wearing clothing that 
have the tendency to give off coloring (e.g. when wet 
etc.) may cause the upholstery to become permanently 
discolored. By lining the seats with a proper 
intermediate cover, contact-discoloration will be 
prevented.
Wipe leather upholstery with a damp cloth and dry 
thoroughly or clean with Mercedes-Benz approved 
Leather Care. Exercise particular care when cleaning 
perforated leather as its underside should not become 
wet.
Hard plastic trim items
Pour Mercedes-Benz approved Interior Care onto soft 
lint-free cloth and apply with light pressure.
Plastic and rubber parts
Do not use oil or wax on these parts.
Wa r n i n g !
Do not bleach or dye seat belts as this may severely 
weaken them. In a crash they may not be able to 
provide adequate protection.

Premium unleaded gasoline
Caution!
To maintain the engine’s durability and performance, 
premium unleaded gasoline must be used. If premium 
unleaded is not available and low octane fuel is used, 
follow these precautions:
•have the fuel tank filled only partially with unleaded 
regular and fill up with premium unleaded as soon 
as possible,
•avoid full throttle driving and abrupt acceleration,
•do not exceed an engine speed of 3000 rpm, if the 
vehicle is loaded with a light load such as two 
persons and no luggage,
•do not exceed 
2/3 of maximum accelerator pedal 
position, if the vehicle is fully loaded or operating in 
mountainous terrain.Fuel requirements
Use only Premium unleaded meeting ASTM
standard D 439:
The octane number (posted at the pump) must be 
91 min. It is an average of both the Research (R) octane 
number and the Motor (M) octane number: (R+M)/2). 
This is also known as ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates such as 
Ethanol, IPA, IBA and TBA can be used provided the 
ratio of any one of these oxygenates to gasoline does not 
exceed 10%, MTBE not to exceed 15%.
The ratio of Methanol to gasoline must not exceed 3% 
plus additional cosolvents.
Using mixtures of Ethanol and Methanol is not allowed. 
Gasohol, which contains 10% Ethanol and 90% unleaded 
gasoline, can be used.
These blends must also meet all other fuel requirements 
such as resistance to spark knock, boiling range, vapor 
pressure etc..
