Detach the electric air pump.

Reinstall tire valve cap.

Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.

Close the trunk lid.Storing collapsible spare wheel in
wheel well
Before you can store the spare wheel with
collapsible tire in the wheel well you have
to release the air pressure of the tire.

Unscrew valve stem removal tool,
which is part of the valve cap, from tire
valve.

Using the valve stem removal tool,
open tire valve slightly by turning the
tire valve insert counterclockwise to
release air pressure.

When the air pressure has been re-
leased, remove tire valve insert (pro-
tect it from dirt and sand) using the
previously removed tire valve cap.

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 the pump holder.

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.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
To prevent possible injury when unscrewing
air pump filler hose from tire valve after in-
flating the tire, use a rag since the tire valve
could be hot.

Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12-volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.Warning!
G
Never charge a battery while still installed in
the vehicle. Gases may escape during charg-
ing and cause explosions that may result in
paint damage, corrosion or personal injury.!Never invert the terminal connections!!The battery, its filler caps and the vent
tube must always be securely installed
when the vehicle is in operation.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):

Set the clock (
page 90).


Resynchronize the ESP
(page 195).


Re-enter the radio code (see radio
operating instructions).


Resynchronize side windows
