>> Practical hints.
About towingsmart recommends that the vehicle be trans

ported with all wheels off the ground using
flatbed or appropriate wheel lift/dolly equip

ment.!
Use flatbed or wheel lift/dolly equipment
with the key in the starter switch in position0.
Do not tow with sling
type equipment. Towing
with sling
type equipment over bumpy roads
will damage radiator and supports.
To prevent damage during transport, do not
tie down the vehicle by its chassis or suspen

sion parts. Use the towing eye.
Switch off the tow

When circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground or
front wheels raised only so far as necessary
to have the vehicle moved to a safe location
where the recommended towing methods can
be employed.
!
If the vehicle is towed with the front axle
raised, the gear selector lever must be in
neutral positionN and the engine must be shut

Work on engine electronics
!
Always have maintenance work on the en

gine electronics and components, such as
control modules, sensors and connecting ca

bles, performed by a qualified specialist who
has the necessary knowledge and tools to
carry out the work required, e.g. at a smart
center. Otherwise there is a danger that vehi

cle components may wear more rapidly, which
may void the vehicle’s warranty.
Retrofitting electrical and elec

tronic devicesElectrical and electronic devices can endan

ger vehicle operating safety.!
Damage or consequential damage due to
retrofitting a device in the vehicle is not co

vered by smart's warranty.
If you install telephones or radio transmitters
in the vehicle you must have such retrofits ap

proved. smart approves the installation of
telephones and radio devices if the work is
done professionally and the device is con

nected to a low
reflection exterior antenna.
G
Warning!
Always have maintenance work on engine
electronics and components performed
by a qualified specialist, e.g. at a smart
center. In particular, work relevant to
safety or on safety related systems must
be carried out at a qualified specialist
workshop.

Warning!
Radio transmitters can interfere with the
vehicle's electronic system, endanger
the operating safety of the vehicle and
thus your own safety, if
• there is no external antenna
• the external antenna is not low
reflec

tion
• the external antenna is incorrectly in

stalled
Excessive electromagnetic radiation can
damage your health and that of others.
Using an external antenna addresses and
considers the concerns currently being
discussed in scientific circles about the
health hazards possibly posed by elec

tromagnetic fields.
Because of this, have the external anten

na installed exclusively at a qualified
specialist workshop which has the neces

sary specialist knowledge and tools to
carry out the work required, e.g. at a
smart center. In particular, work rele

vant to safety or on safety
related sys

tems must be carried out at a qualified
specialist workshop.
