Roadside Assistance button  
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 
message “ROADSIDE ASSISTANCE – CONNECTING 
CALL” will appear in the multifunction display. When 
the connection is established, the message “ROADSIDE 
ASSISTANCE – CALL CONNECTED” appears in the 
multifunction display. 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. When a voice connection is established the 
audio system mutes and the message “TELE AID – 
ROADSIDE ASSISTANCE CALL ACTIVE” appears in the 
multifunction display. 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.
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.

Important!
If the electronic key is left in the starter switch 
position 0 for a extended period of time, it can no longer 
be turned in the lock. In this case, remove electronic key 
from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible 
dead battery, always remove the electronic key from the 
starter switch. 
Do not leave the electronic key in starter 
switch position 0. Notes:
A warning sounds when the driver’s door is opened 
with the electronic key is in starter switch position 1 
or 0.
If the electronic key cannot be turned in the starter 
switch, the vehicle battery may not be sufficiently 
charged. See battery on page 336 or jump starting on 
page 338.
With the engine at idle speed, the charging rate of the 
alternator (output) is limited.
It is therefore recommended that you turn off 
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of 
the battery.
Unnecessary strain on the battery and charging system 
may be minimized by turning off the following power 
consumers, for example:
Heated seats, rear window defroster. In addition, the 
automatic climate air volume control should be set to 
the lowest position.

Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine 
compartment on the right hand side.
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. 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 
electronic key is in starter switch position 0. The 
battery, its filler caps, the vent tube and the opposite 
plug must always be securely installed when the vehicle 
is in operation.
While the engine is running the battery terminal clamps 
must not be loosened or detached, otherwise the 
generator and other electronic components would be 
damaged.
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 if necessary.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.

Jump starting Important!
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 it 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 on the 
right hand side.

Negative (–) under hood terminal
2 Positive (+) under hood terminal
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 (+) under hood 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. 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.
