Warning!G
The dimensions of the spare wheel with col-
lapsible tire are different from those of the
road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel mounted. Adapt your
driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a spare
wheel is mounted.
i
Open doors only when conditions are
safe to do so.

Flat tire
Insert electrical plug 3 into vehicle
cigarette lighter socket (
page 263).
Turn the SmartKey in the starter switch
to position1.
PressI on electric air pump switch 2.
The electric air pump should now
switch on and inflate the collapsible
tire.
Inflate the tire to approximately 51 psi
(3.5 bar).
This takes about 5 minutes for the col-
lapsible tire. Air hose 4 and union
nut5 can become hot during infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.
Press0 on electric air pump switch 2.
Turn the SmartKey in the starter switch
to position0.
If the tire pressure is above 51 psi
(3.5 bar), release excess tire pressure
using the vent screw.
Detach the electric air pump.
Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the trunk.
!
The cigarette lighter (page 262) is
not designed for use with the electric
air pump. Use the power outlet in the
rear passenger compartment
(
page 263) for electric air pump
operation.
!
Do not operate the electric air pump
longer than 6 minutes without interrup-
tion. Otherwise it may overheat.
You may operate the electric 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.
