A discharged battery can freeze at approx. +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 it exploding, causing
personal injury.
Jumper cable specifications:
•Minimum cable cross-section of 25 mm
2 or
approx. 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 trunk under the right-hand
wheel well cover panel.
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.

Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.
•Apply parking brake and shift selector lever to
position “P”.
Important!
3. Clamp one end of the first jumper cable to the
positive (+) terminal of the discharged battery and
the other end to the positive (+) terminal of the
charged battery. Make sure the cable clamps do not
touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
under hood terminal of the disabled vehicle.Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter.

With the automatic central locking activated and the
electronic key in starter switch position 2 (vehicles with
KEYLESS-GO: in “On” position, see page 224), the
vehicle doors lock if the left front wheel as well as the
right rear wheel are turning at vehicle speeds of approx.
9 mph (15 km/h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking. See
“VEHICLE” under “Individual settings” on page 144.
Towing of the vehicle should only be done using the
properly installed towing eye bolt. Never attach tow
cable, tow rope or tow rod to vehicle chassis, frame
or suspension parts.
Note:
The selector lever will remain locked in position “P” and
the electronic key could not be turned in the starter
switch if the battery is disconnected or discharged. See
battery on page 346 or jump starting on page 349.
Wa r n i n g !
Prior to towing the vehicle with all wheels on the
ground, make certain that the electronic key is in
starter switch position 2.If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no
longer be turned in the switch. In this case, the
steering is locked. To unlock, remove electronic key
from starter switch and reinsert.
