Press I on the electric air pump switch 2. The electric air pump should now switch on and inflate the tire. Inflate the spare tire: SL 550 to 36 psi (2.5 bar) SL 600, SL 55 AMG, SL 55 AMG (Performance Package*), and SL 65 AMG to 51 psi (3.5 bar) This takes about 5 minutes. Air hose 4 and union nut 5 can become hot during inflation. Exercise proper caution to avoid burning yourself when using the equipment. ! Compare the recommended tire inflation pressure for your vehicle with the tire inflation pressure on the yellow label located on the spare wheel rim. If the tire inflation pressure on the yellow label on the spare wheel rim differs from the values given in this Operator's Manual, inflate the tire to the recommended tire inflation pressure given on the yellow label on the spare wheel rim. If the spare tire inflation pressure is above the recommended tire inflation pressure for the respective collapsible tire ( page 440), release excess spare tire inflation pressure using the vent screw. Warning! G ! Do not operate the electric air pump longer than 8 minutes without interruption. Otherwise it may overheat. You may operate the air pump again after it has cooled off. Follow recommend inflation pressures. 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. Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Press 0 on the electric air pump switch 2. Turn the SmartKey in the starter switch to position 0. or Press KEYLESS-GO* start/stop button on the gear selector lever twice without depressing the brake pedal. The electric air pump should now be switched off. Detach the electric air pump. Stow the electrical plug and the air hose behind the flap and place the air pump back in the trunk. 411

²
If the spare tire inflation pressure is
above the recommended tire inflation
pressure for the respective collapsible
tire (

page
440), release excess spare
tire inflation pressure using the vent
screw.
²
Detach the electric air pump.
²
Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
!
Compare the recommended tire inflation
pressure for your vehicle with the tire inflation
pressure on the yellow label located on the spare
wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the tire to
the recommended tire inflation pressure given
on the yellow label on the spare wheel rim.
!
Do not operate the electric air pump longer
than 8
minutes without interruption. Otherwise it
may overheat.
You may operate the air pump again after it has
cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
