Possible solution
A
Reserve fuel
The fuel level has dropped below the re-
serve mark.
Refuel at the next gas station
(page 321).
Gas cap is open
A loss of pressure has been detected in
the fuel system. The fuel cap may not be
closed properly or the fuel system may be
leaky.
Check the fuel cap (
page 321).
If it is not closed properly:
Close the fuel cap.
If it is closed properly:
Have the fuel system checked by an au-
thorized Mercedes-Benz Center.
»
Replace air cleaner
The air cleaner is clogged.
Have the air cleaner checked by an au-
thorized Mercedes-Benz Center.
[
Clean fuel filter
Diesel engine:
There is water in the fuel filter.
Have the water drained by an autho-
rized Mercedes-Benz Center as soon as
possible.

438 Practical hintsUnlocking/locking in an emergency
If necessary, lock the trunk with the
mechanical key (
page 126).
Except for the driver’s door, the vehicle
should now be locked.
Insert the mechanical key2 into the
driver’s door lock until it stops.
Turn the mechanical key2 clockwise
to position1.
The driver’s door is locked.Manually unlocking the gear selector
lever
In case of power failure, the gear selector
lever can be manually unlocked, e.g. to tow
the vehicle.
1Pin
Open the storage compartment in the
center armrest (
page 285).
Take out the cup holder (
page 285).
Insert a suitable object1 (e.g. a pin)
through the hole and press the pin
downward.
Remove pin1.

screw
5Union nut
Open flap 1 on electric air pump.
Pull out electrical plug 3 and air hose
with pressure gauge 4.
Remove the valve cap from the
collapsible tire valve.
Screw union nut5 onto the collaps-
ible tire valve.
Insert electrical plug 3 into vehicle
cigarette lighter socket.
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.
!
Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again af-
ter it has cooled off.
Warning!
G
Follow recommend tire 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.

Bleeding the fuel system (diesel engine only)
Bleeding the fuel system (diesel engine only)
Driving the vehicle until the fuel tank is
empty is not recommended. Otherwise, air
may be sucked into the fuel system. If this
happens, theú malfunction indicator
lamp (USA only) or the ±malfunction
indicator lamp (Canada only) comes on
and the engine may not start immediately
after refueling the vehicle.
After refueling:
Make sure the gear selector lever is set
to P.
Do not depress the accelerator.
Turn the SmartKey in the starter switch
to position2 (
page 38) for at least
10 seconds.
Return the SmartKey in the starter
switch to position0 (
page 38).
Turn the SmartKey in the starter switch
to position3 (
page 38) and hold it
there for a maximum of 40 seconds or
until the engine runs surge-free.If the engine does not start:
Wait for approximately 2 minutes.
Turn the SmartKey in the starter switch
to position3 (
page 38) and hold it
there for a maximum of 40 seconds or
until the engine runs surge-free.
If the engine still does not start, do not
make any further attempts to start the en-
gine. Contact an authorized
Mercedes-Benz Center or call Roadside
Assistance (
page 297).
i
Where theú malfunction indicator lamp
(USA only) or the± malfunction indicator
lamp (Canada only) in the instrument cluster has
been illuminated for the above condition, it will
remain illuminated until the engine was cycled
on and off four times in a row.

464 Practical hintsJump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:
Jump starting should only be performed
when the engine and catalytic
converter
1 are cold.
Do not start the engine if the battery is
frozen. Let the battery thaw out first.
Only jump start from batteries with the
same voltage rating (12 V). Jump start-
ing with a higher voltage battery could
damage the vehicle’s electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.
Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when the engine is
started or running.
Warning!
G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!
Do not tow-start the vehicle.
!
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If the engine does not run after several unsuc-
cessful starting attempts, have it checked at the
nearest authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the
catalytic converter
1.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still at-
tached to a battery.
