your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, you should determine the proper tire inflation pressure for those
tires.
As an added safety feature, your vehicle has been equipped with a tire pressur emonitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly underinflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also increases energy consumption, reduces tire tread life, and may affect
the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if underinflation has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS malfunction indicator is combined with the
low tire pressure telltale. When the system detects amalfunction, the telltale will flash for
approximately 1 minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of
incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to function properly. What to do if ...

Please make sure to refer to the
description of the tire repair kit in your
vehicle before sealing a tire.
The tire repair kit can be used to seal
punctures of up to approximately 0.16 in
(4 mm) on the tire tread.
The tire repair kit enables you to drive on
the sealed tire to the nearest authorized
electric drive smart center.
X You should have the sealed tire replaced
at an authorized electric drive smart
center. G
WARNING
Take care not to allow the contents of the
tire sealant to come in contact with hair,
eyes or clothing. The tire sealant is
harmful if inhaled, swallowed or absorbed
through the skin - causes skin, eye and
respiratory irritation. Wear gloves while
using this product if they are available.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with the tire
sealant, change clothing as soon as
possible.
In case of allergic reaction or rash, consult
a physician immediately. Notes
R Small tire punctures, particularly those
in the tread, can be sealed with the tire
sealant.
R The tire sealant can be used in ambient
temperatures from ‑4 ¦(‑20¥ ) to
104¦ (+40¥ ).
R Do not remove any foreig nobjects such as
nails or screws that have penetrated the
tire.
R Do not use the tire sealant if the tire has
been damaged by being driven when
insufficiently inflated (e.g. bumps,
cuts, cracks etc. on the tire). R
Allow escaped tire sealant to dry, then
peel it off.
R Immediately wash all painted surfaces
that came into contact with the tire
sealant using a damp cloth.
R Avoid skin and eye contact with the tire
sealant.
R Do not swallow the tire sealant.
R Allow the tire sealant that is inside the
damaged tire to dry and dispose of
together with the tire.
R Do not use the tire sealant after the
expiration date has elapsed (see top of
container).
Instead, have it replaced at an
authorized electric drive smart center. G
WARNING
The tire sealant is alimited repair device.
The tire sealant cannot be used for cuts or
punctures larger than approximately
0.16 in (4 mm) and tire damage caused by
driving with extremely low tire inflation
pressure, or on a flat tire, or a damaged
wheel.
Do not drive the vehicle under such
circumstances.
If you are unsure of the condition of the tire
or have any question whatsoever about its
suitability for driving contact the nearest
authorized electric drive smart center for
assistance or call Roadside Assistance. G
WARNING
Please review the instructions below for
using the tire repair kit. If you are not
confident that you can competently follow
the instructions for using this kit, do not
use the kit, but instead call for Roadside
Assistance. G
WARNING
Keep the tire sealant out of reach of
children. If swallowed, rinse mouth
immediately with plenty of water and drink
plenty of water. Flat 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.
Keep children away.

The electrical fuses in your vehicle serve
to switch off malfunctioning power
circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating. G
WARNING
Only use fuses approved by smart with the
specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse this may cause an
overload leading to a fire, and/or cause
damage to electrical components and/or
systems. Contact an authorized electric
drive smart center if you encounter any
electrical problems.
! A blown fuse must be replaced by an
appropriate spare fuse (recognizable by
its color or the fuse rating given on the
fuse) of the amperage recommended in
the fuse chart. Any smart center will be
glad to advise you on this subject. 198
Fuses>> Practical hints.
If a newly inserted fuse blows again, have
the cause determined and rectified at an
authorized electric drive smart center.
Before replacing fuses:
R Engage the parking brake.
R Make sure the gear selector lever is in
park position P.
R Turn off all electrical accessories.
R Switch off the drive system.
