Warning!
Failure to follow these instructions can
result in severe injury or death.
Observe all safety instructions and
precautions when handling automotive
batteries (

page 271).
Never lean over batteries while connect

ing, 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.
G
Warning!
Do not place any metal objects on a bat

tery. You could otherwise cause a short
circuit and the battery’s highly flammable
chemicals could ignite.
Never allow any metal object to contact
both battery terminals or the positive
terminal and the vehicle body at the same
time. This might short circuit the battery
and ignite the highly flammable and ex

plosive hydrogen gas generated by the
battery, causing serious personal injury.
G
Warning!
Keep flames or sparks away from battery,
avoid improper connection of jumper
cables, smoking, etc.
• When disconnecting the battery, always
disconnect the negative terminal first,
followed by positive terminal.
• When connecting the battery, always
connect the positive terminal first, fol

lowed by the negative terminal.
• Do not loosen or disconnect the
battery terminal clips while the engine
is running or the key is in the starter

Jump starting
276
>> Practical hints.
!
Do not tow start vehicle.
!
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized smart cen

ter.
Excessive unburned fuel generated by
repeated failed starting attempts may damage
the catalytic converter and may present a fire
risk.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still
attached to a battery.If the battery is discharged, the engine can be
started with jumper cables and the battery of
another vehicle. Observe the following:
• Jump starting should only be performed
when the engine and catalytic converter are
cold.
• Do not start the engine if the battery is
frozen. Let the battery thaw out first.
• Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a higher voltage battery could damage
the vehicle’s electrical system, which will
not be covered by the smart Limited
Warranty.
• Only use jumper cables with sufficient
cross
section and insulated terminal
clamps.
• Always make sure the jumper cables are not
on or near pulleys, fans or other parts that
move when an engine is started or running.
G
Warning!
Failure to follow these directions will
cause damage to the electronic compo

nents, and can lead to a battery explosion
and severe injury or death.
Never lean over batteries while connect

ing or jump starting, you might get in

jured.
Battery fluid contains sulfuric acid. Do
not allow this fluid to come in contact with
eyes, skin or clothing. In case it does, im

mediately flush affected area with water,
and seek medical help if necessary.
