hind the wheel that is diagonally oppo-
site to the wheel being changed.
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire pressure and do not exceed
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.

292 Practical hintsFlat tire
Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.Inflating the spare tire

Take the electric air pump out of the
trunk.
1 Flap
2 Air hose with pressure gauge and vent
screw
3 Union nut
4 Electrical plug
Please exercise appropriate caution

Open flap 1 on air pump.

Pull out electrical plug 4 and air hose
with the pressure gauge 2.
Observe instructions on air pump label.

Remove the valve cap from valve.

Screw the air hose 2 on to the tire
valve.

Insert electrical plug 4 into vehicle cig-
arette lighter socket.

To switch on the air pump turn the key
in the starter switch to position 1
(page 31).

Operate air pump until the pressure
gauge displays 36 psi (2.5 bar)
This takes about five minutes for the
space tire. The air hose 2 and the union
nut 3 can become hot during inflation.
Warning!
G

Practical hints
Flat tire

To switch off the air pump turn the key
in the starter switch to position
0
(page 31).

If the tire pressure is above 36 psi (2.5
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 air
pump back in the trunk.
!Do not operate the electric air pump
longer than six minutes without inter-
ruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated 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. Underinfalted tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the driver’s door latch
post). Overloading the tires can overheat
them, possibly causing a blowout.
