Located below the center armrest cover is the Roadside 
Assistance button•. Pressing and holding the 
button (for longer than 2 seconds), will initiate a call to 
a Mercedes-Benz Roadside Assistance dispatcher. The 
button will flash while the call is in progress. The 
Tele Aid system will transmit data generating the 
vehicle identification number, model, color and location 
(subject to availability of cellular and GPS signals).
A voice connection between the Roadside Assistance 
dispatcher and the occupants of the vehicle will be 
established. The nature of the need for assistance can 
then be described. The Mercedes-Benz Roadside assistance dispatcher will 
either dispatch a qualified Mercedes-Benz technician or 
arrange to tow your vehicle to the nearest 
Mercedes-Benz Center. For services such as labor and/
or towing charges may apply. Refer to the Roadside 
Assistance manual for more information. 
These programs are only available in the USA:
•Sign and Drive services: Services such as jump start, 
a few gallons of fuel or the replacement of a flat tire 
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits 
the Mercedes-Benz Roadside Assistance dispatcher 
to download malfunction codes and actual vehicle 
data.
Notes:
The indicator lamp in the Roadside Assistance 
button• remains illuminated in red for 
approximately 10 seconds during the system self-check 
after turning key in steering lock to position 2 (together 
with the “SOS” button and the Information 
button¡).
Wa r n i n g !
If you feel at any way in jeopardy when in the 
vehicle (e.g. smoke or fire in the vehicle, vehicle in 
a dangerous road location), please do not wait for 
voice contact after you have pressed the emergency 
button. Carefully leave the vehicle and move to a 
safe location. The Response Center will 
automatically contact local emergency officials 
with the vehicle’s approximate location if they 
receive an automatic “SOS” signal and cannot make 
voice contact with the vehicle occupants.

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. 

223 Jump starting
Te ch n i c a l
data Instruments 
and controlsOperation DrivingInstrument 
cluster displayPractical hintsCar care Index 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” (manual transmission to Neutral).
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 a grounded 
heavy metal bracket in the engine compartment or 
on the engine 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 will 
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.
Note:
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.
