7.Operate air pump (approximately 5 minutes) until 
pressure gauge displays 36 psi (2.5 bar).
8.To switch off air pump, turn key in steering lock to 
position 0.
9.Unscrew filler hose from tire. Reinstall tire valve 
cap.
Note:
Excessive tire air pressure should be released using the 
vent screw.Storing spare wheel in wheel well
Deflate spare tire:
1.Unscrew valve stem removal tool, which is a part of 
the valve cap, from tire valve.
2.Using the valve stem removal tool, open tire valve 
slightly by turning the tire valve insert 
counterclockwise to release air pressure.
3.When the tire air pressure has been released, 
remove tire valve insert (protect it from dirt and 
sand) using the previously removed tire valve cap.
4.Once all air is out of the tire, and the tire has 
collapsed to its original shape, reinstall the tire 
valve insert and valve cap.
Place spare wheel in wheel well and secure it with air 
pump holder. Turn pump holder clockwise to its stop.

cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler f lap) lists the tire inflation 
pressures specified for Mercedes-Benz recommended 
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 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 = approximately +68°F (+20°C) 
and ambient temperature = approximately +32°F (0°C) 
then the adjusted air pressure = specified air pressure 
+3psi (+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 at 
intervals of no more than 14 days are therefore 
essential.

of grille simultaneously pushing apron (arrow) up.
Grille installation for Sport Package: Position bottom 
end of grille and press in securely simultaneously 
pushing apron (arrow) up.
We recommend that the vehicle be transported using 
f lat bed equipment. This method is preferable to other 
types of towing.Do not tow with sling-type equipment. Front towing 
with sling-type equipment over bumpy roads will 
damage radiator and supports. Rear towing with sling-
type equipment over bumpy roads will damage the 
lower edge of the front bumper cover.
Use wheel lift, dolly, or f lat bed equipment, with key in 
steering lock turned to position 0.
Towing restrictions for vehicles with automatic 
transmission: The vehicle may be towed with all wheels 
on the ground and the selector lever in position “N” for 
distances up to 30 miles (50 km) and at a speed not to 
exceed 30 mph (50 km / h). The key must be in steering 
lock position 2.
To be certain to avoid a possibility of damage to the 
transmission, however, we recommend the drive shaft 
be disconnected at the rear axle drive f lange for any 
towing beyond a short tow to a nearby garage.

Wa r n i n g !
With the engine not running, there is no power 
assistance for the braking and steering systems. In 
this case, it is important to keep in mind that a 
considerably higher degree of effort in necessary to 
brake and steer the vehicle.

Important!
When towing the vehicle, please, note the following:
With the automatic central locking activated and the 
key in steering lock position 2, the vehicle doors lock if 
the left front wheel as well as the right rear wheel are 
turning at vehicle speeds of approximately 9 mph 
(15 km / h) or more.
To prevent the vehicle door locks from locking, 
deactivate the automatic central locking.Note:
To signal turns while being towed with hazard warning 
f lash er in u se, turn key in steering  l ock  to position 2 a nd  
activate combination switch for left or right turn signal 
in usual manner – only the selected turn signal will 
operate. Upon canceling the turn signal, the hazard 
warning flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the 
engine must be shut off (key in steering lock position 0 
or 1). Otherwise, the ESP will immediately be engaged 
and will apply the rear wheel brakes. Switch off the 
tow-away alarm as well as the ESP, see page 37 and 170.

Engine cleaning
Prior to cleaning the engine compartment make sure to 
protect electrical components and connectors from the 
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax 
should be applied to the engine compartment after 
every engine cleaning. Before applying, all control 
linkage bushings and joints should be lubricated. The 
poly-V-belt and all pulleys should be protected from any 
wax.Ve h i c l e   w a s h i n g
Do not use hot water or wash your vehicle in direct 
sunlight. Use only a mild car wash detergent, such as 
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of 
water. Direct only a very weak spray towards the 
ventilation intake. Use plenty of water and rinse the 
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a 
chamois. Do not allow cleaning agents to dry on the 
finish.
Due to the width of the vehicle, prior to running the 
vehicle through an automatic car wash, fold back the 
outside mirrors to prevent them from getting damaged.
In the winter, thoroughly remove all traces of road salt 
as soon as possible.
When washing the underbody, do not forget to clean the 
inner sides of the wheels.

Prior to cleaning the inside of the rear window, operate 
hardtop via the switch until rear shelf (1) is in a vertical 
position. Leave key in steering lock position 2.
The roof will remain in this position for approximately 
7 minutes, sufficient time for cleaning the inside of the 
rear window.Wiper blades
Clean the wiper blade rubbers with a clean cloth and 
detergent solution.
Light alloy wheels
Mercedes-Benz approved Wheel Care should be used for 
regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with 
Mercedes-Benz approved Wheel Care, using a soft 
bristle brush and a strong spray of water.
Follow instructions on container.
Note:
Use only acid-free cleaning materials. The acid could 
lead to corrosion.
Instrument cluster
Use a gentle dishwashing detergent or mild detergent 
for delicate fabrics as a washing solution. Wipe with a 
cloth moistened in lukewarm solution. Do not use 
scouring agents.

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.
Headliner and shelf behind roll bars
Clean with soft bristle brush, or use a dry-shampoo 
cleaner in case of excessive dirt.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.
Leather Upholstery
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.
Cloth Upholstery
Clean with soft bristle brush, or use a dry-shampoo 
cleaner in case of excessive dirt.
