WARNING
Batteries contain poisonous and corrosive
substances. Therefore keep the batteries
out of reach of children.
If a battery is swallowed, seek medical help
immediately. Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states/provinces
require sellers of batteries to accept old
batteries for recycling.

About replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is
therefore essential that all bulbs and lamp
assemblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized electric drive smart center for
headlamp adjustment. G
WARNING
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before changing
a bulb. Otherwise you could be burned if you
touch them.
Keep bulbs out of the reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
i If the headlamps or front fog lamps* are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging. Notes on bulb replacement:
R
Only use bulbs of the same type and with
the specified watt rating.
R Switch the lights off before replacing a
bulb to prevent short circuits.
R Always use aclean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil
and grease.
R Avoid touching the glass of the bulb with
bare fingers.
R If the newly installed bulb does not come
on, contact an authorized electric drive
smart center.
R Have the bulbs for the front fog lamps*
and the LED daytime running lamps*
replaced at an authorized electric drive
smart center. 172

auxiliary power outlet (Y page 106).
X Insert the key in the starter switch and
turn it to position 1.
i The vehicle’s 12‑volt battery is drained
by use of the electric air pump. You
should therefore keep the drive system
running while inflating the tire. X
Press Ion electric air pump switch 0018.
The electric air pump is switched on and
inflates the tire.
i First, the sealant is pumped into the
tire. The pressure may briefly increase
to a high value. This is normal and not an
indication of a malfunction. Do not
switch off the electric air pump.
X Let the electric air pump inflate the tire
for a maximum of ten minutes.
Pressure gauge 0003must display at least
180 kPa (1.8 bar, 26 psi). !
Do not operate the electric air pump
longer than ten minutes without
interruption. Otherwise it may overheat.
You may operate the electrical air pump
again after it has cooled off.
X If a tire inflation pressure of at least
180 kPa (1.8 bar, 26 psi) is not attained,
turn off the electric air pump by
pressing 0on electric air pump switch
0018.
X Unscre wthe end of filler hose 002Afrom
tire valve 001D.
X After clearing the area around the
vehicle of people and obstacles, drive
vehicle back or forth very slowly
approximately 30 ft (10 m).
This serves to better distribute the tire
sealant material inside the tire.

Notes on the vehicle’s electrical
system
The vehicle’s electrical system provides
power for the electric drive and all
electrical consumers or components of the
vehicle.
Power is supplied to the vehicle via two
batteries:
R 12-volt battery
R High-voltage battery Notes on the 12‑volt battery
Your vehicle’s 12‑volt battery is located in
the passenger footwell below the footrest
(Y page 192).
The 12 volt battery should always be
sufficiently charged in order to achieve
its rated service life. Refer to the
Scheduled Maintenance Guide (USA only) or
the Service booklet (Canada only) for
battery maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the 12 volt battery charge checked more
frequently.
When replacing the battery, always use
batteries approved by smart. For
information, contact an authorized
electric drive smart center.
If you do not intend to operat
eyour vehicle
for an extended period of time, consult an
authorized electric drive smart center
about steps you need to observe. G
WARNING
Observe all safety instructions and
precautions when handling automotive
batteries. Risk of explosion.
Fire, open flames and
smoking are prohibited
when handling batteries.
Avoid creating sparks.
Battery acid is caustic.
Do not allow it to come
into contact with skin,
eyes or clothing.
Wear suitable protective
clothing, especially
gloves, apron and
faceguard.
Wear eye protection.
Rinse any acid spills
immediately with clear
water. Contact a physician
if necessary.

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

connecting, you might get injured.
Batter yfluid 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 battery.
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 explosive
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.
R When disconnecting the battery, always
disconnect the negative terminal first,
followed by positive terminal.
R When connecting the battery, always
connect the positive terminal first,
followed by the negative terminal.
R Do not loosen or disconnect the battery
terminal clips while the drive system is running or the key is in the starter
switch.
! Never loosen or detach battery terminal
clamps while the drive system is running
or the key is in the starter switch.
Otherwise, electronic components could
be severely damaged.
Have the battery checked regularly at an
authorized electric drive smart center.
Refer to Maintenance Booklet for
maintenance intervals or contact an
authorized electric drive smart center
for further information.
! Never invert the terminal connections! Notes on the high‑voltage battery
Have work on the high-voltage battery
performed by an authorized electric drive
smart center only. Observe the safety notes
on (Y page 15) as well as the notes on the 12-
volt battery (Y page 190). G
WARNING
The electrolyte of the high-voltage
battery, i.e. the battery fluid, is toxic and
caustic. Do not allow this fluid to come in
contact with eyes, skin or clothing, for
example in case of an accident.
In case it does, immediately flush affected
area with water and seek medical help
immediately.
The high-voltage battery is located in the
vehicle underbody. Keep this in mind when
jacking up the vehicle. The vehicle has
designated take-up brackets for the jack.
For more information, see (Y page 189).
! Only position the jack on the
designated take-up brackets.
You must not position the jack under the
