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.
Attempting to jump start a frozen battery
can result in it exploding, causing per-
sonal injury.
Read all instructions before proceeding.
! Do not tow‑start vehicle. You could oth-
erwise seriously damage the transmis-
sion which is not covered by the smart
Limited Warranty.
! 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
center.
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 fully
charged battery of another vehicle or an
equivalent starter pack. Observe the fol-
lowing:
Access to the battery is not possible on
R
all vehicles. If you cannot access the
battery in your vehicle provide jump
start power by an external battery or
starter pack.
Jump starting should only be performed
R
when the engine and catalytic converter
are cold.
Do not start the engine if the battery is
R
frozen. Let the battery thaw out first.
Only jump start from batteries with the
R
same voltage rating (12 V). Jump starting
with a more powerful battery could dam-
age the vehicle's electrical system. Such
damage will not be covered by the smart
Limited Warranty.
Only use jumper cables with sufficient
R
cross-section and insulated terminal
clamps.
Always make sure the jumper cables are
R
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
Should the battery be drained com-
R
pletely, let the donating power source
charge the vehicle for several minutes
before reattempting the starting proc-
ess.
G WARNING

not smoke.
Observe all safety instructions and pre-
cautions when handling automotive batter-
ies.
