cluster displayPractical hints Car care Index Obtaining replacement keys
Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys can only be
obtained from your authorized Mercedes-Benz Center.
Start lock-out
Important!
Removing the key from the steering lock activates the
start lock-out. The engine cannot be started.
Turning the key in the steering lock to position 2
deactivates the start lock-out.
Note:
In case the engine cannot be started, and Á and
î are shown in the odometer display field, the
system is not operational. Contact an authorized
Mercedes-Benz Center or call 1-800-FOR-MERCedes (in
the USA), or 1-800-387-0100 (in Canada).General notes on the central locking system
If the key in the steering lock is in position 2, the
vehicle cannot be locked or unlocked with the remote
control.
If the vehicle cannot be locked or unlocked:
•Check the batteries of the remote control,
seepage236.
•Synchronize the remote control, see page 237.

Unlocking:
Press transmit button Œ. All turn signal lamps blink
once to indicate that the vehicle is unlocked.
The remote control can be programmed for two kinds of
unlocking modes (see below):
Selective unlocking mode –

storage compartment in armrest, and fuel filler flap.
Press transmit button Πtwice to unlock both doors,
storage compartment in armrest, fuel filler flap, and
trunk.
Global unlocking mode –
Press transmit button Πonce to unlock both doors,
storage compartment in armrest, fuel filler flap, and
trunk.
Notes:
The presently active unlocking mode (selective or
global) can only be determined by unlocking the vehicle
with the remote control (see below for changing mode).If within 40 seconds of unlocking with the remote
control, neither door is opened, the key is not inserted
in the steering lock, or the central locking switch is not
activated, the vehicle will automatically lock.
Locking:
Press transmit button ‹ once. All turn signal lamps
blink three times to indicate that the vehicle is locked.
If the turn signal lamps do not blink, a door or trunk is
not closed properly.
Note:
If the vehicle cannot be locked or unlocked by pressing
the transmit button, then it may be necessary to change
the batteries in the remote control (if ok, battery check
lamp in transmitter will light briefly when transmitting)
or to synchronize the remote control, see page 236
and 237.

If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition. Spare tire will age and become worn over
time even if never used, and thus should be inspected
and replaced when necessary.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, 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.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc..

221 Battery
Te ch n i c a l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components will be
damaged.Battery recycling
Batteries contain materials that can harm the
environment with improper disposal.
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.

Jump startingImportant!
A discharged battery can freeze at approximately +14°F
(–10°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in exploding, causing personal
injury.
Jumper cable specifications:
•Minimum cable cross-section of 25 mm
2 or
approximately 2 AWG
•Maximum length of 11.5 ft. (3.5 m).
If the battery is discharged, the engine should be started
with jumper cables and the (12 V) battery of another
vehicle.
Only use 12 V battery to jump start your vehicle. Jump
starting with more powerful battery could damage the
vehicle’s electrical systems, which will not be covered
by the Mercedes-benz Limited Warranty.
The battery is located in the engine compartment.
Wa r n i n 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..Read all instructions before proceeding.
