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
personal injury.
Read all instructions before proceeding.
! Do not tow‑start vehicle. You could
otherwise seriously damage the
transmission
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
following:
R Access to the battery is not possible on
all vehicles. If you cannot access the
battery in your vehicle provide jump start power by an external battery or
starter pack.
R Jump starting should only be performed
when the engine and catalytic converter
are cold.
R Do not start the engine if the battery is
frozen. Let the battery thaw out first.
R Only jump start from batteries with the
same
voltage rating (12 V). Jump starting
with a more powerful battery could
damage the vehicle’s electrical system.
Such damage will not be covered by the
smart Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained
completely, let the donating power
source charge the vehicle for several
minutes before reattempting the
starting process. G
WARNING
Keep flames or sparks away from battery. Do
not smoke.
Observe all safety instructions and
precautions when handling automotive
batteries. 200

About towing
This section offers information on towing
methods for breakdown situations,
emergency towing, and flat towing smart
vehicles. Recommended towing method -
Breakdown situation
smart recommends that the vehicle be
transported with all wheels off the ground
using a flatbed carrier truck or
appropriate wheel lift/dolly equipment.
X Switch off the tow‑away protection* and
interior motion sensor*
(Y page 49).
! 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. Emergency towing
When circumstances do not permit the
recommended 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
towing method can be employed. G
WARNING
If circumstances require towing the
vehicle with all wheels on the ground,
always tow with a tow bar if:
R the engine will not run
R there is a malfunction in the brake
system
R there is a malfunction in the power
supply or in the vehicle’s electrical
system
A
tow bar is necessary to adequately control
the towed vehicle.
Prior to towing the vehicle with all wheels
on the ground, make sure the gear selector
lever is in neutral position N and the
ignition is switched off. G
WARNING
With the engine not running, there is no
power assistance for the brake and
steering* systems. In this case, it is
important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the vehicle.
Adapt your driving accordingly.
! Do not tow the vehicle with the front
axle raised. Doing so may cause serious
damage to the brake system which is not
covered by the smart Limited Warranty.
! Before towing the vehicle observe the
following instructions:
R Do not tow with sling-type equipment
attached
to suspension parts. This may202

cause damage to the radiator and other
supports if towing on a bumpy road.
R Towing
the vehicle should only be done
using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope, or tow rod to the vehicle chassis,
frame, or suspension parts.
! Make sure the ignition is switched off
while towing the vehicle. Doing
otherwise may result in
R the ESP ®
being activated. Active
braking action through the ESP ®
may
seriously damage the brake system
which is not covered by the smart
Limited Warranty.
R a discharged battery.
! Make sure the gear selector lever is in
neutral position N while towing the
vehicle. Doing otherwise may result in
significant transmission damage.
! Towing the vehicle with a luggage
rack* mounted is not permissible. The
vehicle must not be towed by the luggage
rack*.
i If the battery is disconnected or
discharged, the gear selector lever will
remain locked in park position P.
Contact an authorized smart center for
assistance or call Roadside Assistance.
Towing eye bolt The towing eye bolt is located in the
passenger footwell under the carpet.

Installing towing eye bolt
Depending of whether you are towing a
vehicle
or being towed, the towing eye bolt
can be screwed into threaded holes which
are located behind covers on the front and
rear bumper. Front cover

WARNING
High outside temperature, stop-and-go
traffic, driving on long uphill grades, or
driving
at high engine speed may increase
the temperature in the engine
compartment. Therefore the area around the
air slots in the rear apron may be hot. Let
the engine cool off before touching this
area to prevent burns. Towing

hole for the towing eye bolt.
X Screw towing eye bolt in clockwise to its
stop and tighten with a suitable object. G
WARNING
For safety reasons, recovery or lashing
down of the vehicle by means of the towing
eye is not allowed. Failure to observe this
could
result in the towing eye being ripped
out of its mounting and people being
injured.
Towing the vehicle X

left as it will go when switching off the
ignition.
X Switch off the ignition.
X Leave the key in the starter switch. X
Switch on the hazard warning flasher.
X Release the parking brake. Flat towing
Flat towing is when all wheels of the
vehicle are on the ground during the tow.
For vehicles that will be flat towed over
long distances observe the following
recommendations:
X Preparing the vehicle: Contact an
authorized
smart center for information
on recommended tow bar equipment and
installing a matching on/off switch on
the battery terminal.
X Before towing:
Make sure the ignition is
switched on.
X Engage the parking brake.
X Depress the brake pedal and keep it
pressed.
X Move the gear selector lever to neutral
position N.
X Release the brake pedal.
i With the gear selector lever in neutral
position N,
the key cannot be turned fully
to starter switch position 0. Therefore
turn the key in the starter switch as far
left as it will go when switching off the
ignition.
X Switch off the ignition.
X Leave the key in the starter switch.
X Wait approximately 30 seconds until the
multifunction display in the instrument
cluster is completely blank.
X Turn the battery off using the previously
installed battery switch.
X Release the parking brake.
X During towing: Make sure the gear
selector lever remains in neutral
position N with the ignition switched
off.
X After towing: Engage the parking brake.204

R in a discharged battery. Fuses
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 a 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.
If a newly inserted fuse blows again, have
the cause determined and rectified at an
authorized 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 Turn off the engine.
R Remove the key from the starter switch. Replacing a fuse
