Important!
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.
2AWG
•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 trunk floor.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 (–)
terminal (2) of the discharged battery.
