Te ch n i c a l

cluster displayPractical hints Car care Index 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
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. Sign and Drive services (jump start, a
few gallons of fuel or the replacement of a flat tire with
the vehicle spare tire) are available.
If the vehicle requires more than Sign and Drive
services, 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 other than Sign and Drive services, labor and / or
towing charges may apply. Refer to the Roadside
Assistance manual for more information.
Notes:
The indicator lamp in the Roadside Assistance
button remains illuminated in red for
approximately 5 seconds during the system self-check
after turning electronic key in starter switch to
position 2 (together with the “SOS” button and the
Information button¡).
See system self-check on page 220 when the indicator
lamp does not light up in red or stays on longer than
approximately 5 seconds.
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 “SOS” signal and cannot make voice
contact with the vehicle occupants.

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 starting
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
clot hin g. In cas e i t d oes , i mm ed ia tely f lus h a f fected
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.

319 Jump starting
Te ch n i c a l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index 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.1Negative (–) 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.
