Always make sure that neither you nor the bat-
tery is electrostatically charged. There is a
build-up of electrostatic charge, e.g.:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the
carpet or other synthetic materials
Rif you wipe the battery with a cloth.
GWARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is a risk of an explo- sion.
RMake sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
RNever place metal objects or tools on a
battery.
RIt is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe
the described order when connecting and
disconnecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
HEnvironmental note
Batteries contain danger-
ous substances. It is
against the law to dispose
of them with the household
rubbish. They must be col-
lected separately and recy-
cled to protect the envi-
ronment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified
specialist workshop or a
special collection point
for used batteries.
!Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Main-
tenance Booklet or contact a qualified spe-
cialist workshop for more information.
!You should have all work involving the
battery carried out at a qualified special-
ist workshop. In the exceptional case that
it is necessary for you to disconnect the
battery yourself, make sure that:
Ryou switch off the engine and remove the
SmartKey. Check that all the indicator
lamps in the instrument cluster are off.
Otherwise, electronic components, such
as the alternator, may be damaged.
Ryou first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
The battery and the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precautions and take pro-
tective measures when handling batteries.
WARNING

Battery acid is caustic. Avoid con-
tact with skin, eyes or clothing.
Wear suitable protective clothing,especially gloves, apron and face-
guard.
Rinse any acid spills immediately
with clear water. Contact a physi-
cian if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, smart recommends that you
only use batteries which have been tested and
approved specifically for your vehicle by
smart. These batteries provide increased
impact protection to prevent vehicle occu-
pants from suffering acid burns should the
battery be damaged in the event of an acci-
dent.
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Like other batteries, the vehicle battery may discharge over time if you do not use the
vehicle. In this case, have the battery dis-
connected at a qualified specialist work-
shop. To maintain the charge, you can also
charge the battery with a charger recommen-
ded by smart. Contact a qualified specialist
workshop for further information.
Have the battery charge status checked more
frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for
a lengthy period. Consult a qualified spe-
cialist workshop if you wish to leave your
vehicle parked for a long period of time.
When replacing a battery, only use a battery
recommended by smart.
iRemove the SmartKey if you park the vehi-
cle and do not require any electrical con-
sumers. The vehicle will then use very lit-
tle energy, thus conserving battery power.
Charging the battery
GWARNING
During charging and jump-starting, explo- sive gases can escape from the battery.
There is a risk of an explosion.
Particularly avoid fire, open flames, cre-
ating sparks and smoking. Ensure there is
sufficient ventilation while charging and
jump-starting. Do not lean over a battery.
GWARNING

Avoid contact with skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
GWARNING
A discharged battery can freeze at temper-
atures below freezing point. When jump-
starting the vehicle or charging the bat-
tery, gases can escape from the battery.
There is a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a maximum
charging voltage of 14.8 V.
XOpen the service cover (Ypage 151).
XConnect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor battery
in the jump-starting procedure
(
Ypage 168).
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the dis-
charged battery has frozen. In this case you
may neither jump-start the vehicle nor
charge the battery. The service life of a
thawed-out battery may be shorter. The start-
ing characteristics can be impaired, partic-
ularly at low temperatures. Have the thawed-
out battery checked at a qualified specialist
workshop.
