XIf the tire inflation pressure is at least
130 kpa (1.3 bar, 20 psi), inflate or deflate
the tire to correct tire inflation
pressure (see Tire and Loading
Information placard located on the
driver’s door B‑pillar).

! The manufacturer is unable to
guarantee that all tire punctures can be
repaired with the tire repair kit, in
particular cuts or perforations larger
than approximately 0.16 in (4 mm) or away
from the tire’s tread. The manufacturer
is not liable for damage sustained
through improper use of the tire repair
kit.GWarning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.

center, to have the damaged tire

soon as possible to obtain a new filler
hose and a new tire sealant container.XBring used tire sealant materials to an
authorized smart center for proper
disposal.XReplace your tire sealant container
every 4 years. Replacement containers
are available at any authorized smart

GWarning!
When jacking up the vehicle, only use a
suitable jack. Observe the manufacturer’s
safety instructions.
The jack must be designed for jacking up
this vehicle at the jack take-up brackets
built into both sides of the vehicle.
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle. To help avoid personal
injury, use the jack only to lift the vehicle
during a wheel change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
Always firmly engage the parking brake and
block the wheels with wheel chocks or other
sizeable objects before raising the
vehicle with the jack. Do not release the
parking brake while the vehicle is raised.
Make sure the ground on which the vehicle
is standing and where you place the jack is
solid, level and not slippery. If necessary,
use a large underlay. On slippery surfaces,
such as tiled floors, you should use a non-
slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
The jack must always be vertical when in
use. Always try to use the jack on level
surface. If you do not position the jack
correctly, the vehicle can fall off the jack
and seriously or fatally injure you or
others.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.XMake sure to have a suitable jack 18

wrench 18
and wheel chock 18
.
Contact an authorized smart center for
information on which jack and wheel
wrench are required.XPrepare the vehicle as described
( Y page 193).XMake sure the surface is level.
Prevent the vehicle from rolling away by
blocking wheels with wheel chocks or other
sizeable objects:

object in front of and another wheel
chock or other sizeable object behind
the wheel that is diagonally opposite to
the wheel being changed.18 Not included and not available as factory equipment.Wheel change193>> Practical hints.BA 451 USA, CA Edition A 2011; 1; 4, en-UShereepeVersion: 3.0.3.62010-05-11T15:12:26+02:00 - Seite 193Z

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
