Driving when your engine is overheated can cause some fluids which may have leaked into
the engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle until the engine has cooled down.
! Among other possible causes, the poly-V-belt could be broken. Do not continue to
drive. Otherwise, the engine will overheat due to an inoperative water pump which may
result in damage to the engine.

Using the tire repair kit
! Depending on the type of damage on the
tire, the tire sealant could damage the
sensor of the Tire Pressure Monitoring
System (TPMS)*. Such damage is not
covered by the smart Limited Warranty.
When having the damaged tire replaced,
also have the TPMS sensors* checked for
proper function. When the sensor is
damaged, the TPMS* will not function
properly. The sensor must then be
replaced at an authorized smart center as
soon as possible.
The tire repair kit can be used to seal
punctures of up to approximately 0.16 in
(4 mm) on the tire tread.

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 jumpstart 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.GWarning!
Keep flames or sparks away from battery. Do
not smoke.
Observe all safety instructions and
precautions when handling automotive
batteries.

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.
XSwitch 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.
GWarning!
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.
GWarning!
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 may

are prohibited when windshield washer
concentrate is being handled.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which
provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35 ¦ (-37 ¥) and
corrosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0
Anticorrosion/Antifreeze separately
from each other, could cause engine
damage not covered by the smart Limited
Warranty.
If the antifreeze mixture is effective to
-35 ¦ (-37 ¥), the boiling point of the
coolant in the pressurized cooling system
is reached at approximately 266 ¦
(130 ¥ ).
The coolant solution must be used year
round, even in countries which have high
temperatures to provide the necessary
corrosion protection and increase
boil‑over protection. Refer to
Maintenance/ Service Booklet for
replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze
solution or other smart approved products
of equal specification are used to renew
the coolant concentration or bring it back
up to the proper level.
For information on other smart approved
products of equal specification, contact an
authorized smart center.
To provide important corrosion
protection, the solution must be at least
50% anticorrosion/antifreeze (equivalent
to freeze protection to approximately
-35 ¦ [-37 ¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze
protection to approximately -49 ¦
[(-45 ¥]), the engine temperature will
increase due to the lower heat transfer
capability of the solution. Therefore, do
not use more than this amount of
anticorrosion/antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
Always use anticorrosion/antifreeze that
have been approved by smart. For
information contact an authorized smart
center.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water.
If you are not sure about the water quality,
consult an authorized smart center.
Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines
necessitates that anticorrosion/
antifreeze coolant used in such engines be
specifically formulated to protect the
aluminum parts.
Failure to use such anticorrosion/
antifreeze coolant will result in a
significantly shortened service life.
Therefore, the following product is
strongly recommended for use in your
Service fluids and capacities223>> Technical data.BA 451 USA, CA Edition A 2011; 1; 4, en-UShereepeVersion: 3.0.3.62010-05-11T15:12:26+02:00 - Seite 223Z
