2. Open lid and pull out air hose with pressure gauge and electrical plug.
Observe instructions on air pump label.
3. Unscrew tire valve cap from spare wheel tire valve.
4. Screw filler hose onto tire valve.
5. Plug air pump electrical plug into vehicle cigar lighter.

Wa r n i n g !
To prevent possible injury when unscrewing air
pump filler hose from tire valve after inflating the
tire, use a rag since the tire valve could be hot.

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 air pump and spare wheel in wheel well and
secure them.

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 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
+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 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 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.
