Notes on the vehicle’s electrical sys-
tem
The vehicle’s electrical system provides
power for the electric drive and all elec-
trical 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 199).
The 12 volt battery should always be suffi-
ciently 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 fre-
quently.
When replacing the battery, always use bat-
teries approved by smart. For information,
contact an authorized electric drive smart
center. If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized electric drive smart center
about steps you need to observe. G

About towing
This section offers information on towing
methods for breakdown situations and
emergency towing. Recommended towing method - Break-
down situation
! To prevent damage during transport, do
not tie down the vehicle by its chassis or
suspension parts — use only wheel straps
to position and hold down the vehicle.
Improper tie down on a flatbed carrier
truck or trailer can damage suspension
parts and body panels.
smart recommends that the vehicle be
transported with all wheels off the ground
using a flatbed carrier truck or appropri-
ate wheel lift/dolly equipment.
Always have your vehicle transported:
R when the 0075warning lamp for the high-
voltage system lights up in the instru-
ment cluster
R when the Do not tow (away)
Do not tow (away) message
appears in the instrument cluster
R when the multifunction display is inop-
erative R
when one or several of the following
warning lamps light up:
-00ED Drive diagnostics (red)
- 003D 12‑Volt battery
0052 Power steering
R if the brake pedal already starts to pul-
sate just after towing begins
R if you have to transport the vehicle over
long distances
X Switch off the tow‑away protection* and
interior motion sensor* (Y page 50). Emergency towing
When circumstances do not permit the rec-
ommended towing method, the vehicle may
be towed with all wheels on the ground
using a strap or tow bar connected to
another vehicle. Only tow the vehicle as far
as necessary to have the vehicle moved to a
safe location where the recommended tow-
ing method can be employed. G
WARNING
If circumstances require towing the vehi-
cle with all wheels on the ground, always tow
with a tow bar if:
R the drive system will not run
R there is a malfunction in the brake sys-
tem
R there is a malfunction in the power sup-
ply or in the vehicle’s electrical system Towing
