289 Operation
At the gas station
Open the fuel filler flap by pushing at
the point indicated by the arrow1.
The fuel filler flap springs open.
Turn the fuel cap counterclockwise and
hold on to it until possible pressure is
released.
Take off the cap and set it in direction
of arrow3 the recess on the fuel filler
flap.
To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.
Only fill your tank until the filler nozzle
unit cuts out – do not top up or
overfill.
Replace the fuel cap by turning it clock-
wise.
You should hear the fuel cap engage.
Close the fuel filler flap.
Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.
iUse only premium unleaded gasoline
with a minimum Posted Octane Rating
of 91 (average of 96 RON / 86 MON).
Information on gasoline quality can
normally be found on the fuel pump.
More information on gasoline can be
found in the Factory Approved Service
Products pamphlet.
Flexible Fuel Vehicles are identified by
a label reading Premium gasoline or
E85 only! on the fuel filler flap.
For more information, see “Flexible
Fuel Vehicles” (
page 431).
iLeaving the engine running and the fuel
cap open can cause the ú malfunc-
tion indicator lamp (USA only) or the
± malfunction indicator lamp
(Canada only) to illuminate.
For more information, see “Practical
hints” section (
page 342).

399 Practical hints
Flat tire
Open flap1 on electric air pump.
Pull out electrical plug3 and air hose
with pressure gauge4.
Remove the valve cap from valve.
Screw air hose4 onto the tire valve.
Insert electrical plug3 into vehicle
cigarette lighter socket.
Turn the SmartKey in the starter switch
to position1.
Press I on electric air pump switch 2.
The electric air pump should now
switch on and inflate the spare tire.
Inflate the spare tire to approximately
36 psi (2.5 bar).
This takes about five minutes for the
spare tire. Air hose4 and union
nut5 can become hot during infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.
Press0on electric air pump switch2.
Turn the SmartKey in the starter switch
to position0.
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
interruption. Otherwise it may over-
heat.
You may operate the electric air pump
again after 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. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.

This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.
