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.
