About towing
This section offers information on towing
methods for breakdown situations and
emergency towing. Recommended towing method - Break-
down situation
! 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.
smart recommends that the vehicle be
transported with all wheels off the ground
using a flatbed carrier truck or appropri-
ate wheel lift/dolly equipment.
Always have your vehicle transported:
R when the 0075warning lamp for the high-
voltage system lights up in the instru-
ment cluster
R when the Do not tow (away)
Do not tow (away) message
appears in the instrument cluster
R when the multifunction display is inop-
erative R
when one or several of the following
warning lamps light up:
-00ED Drive diagnostics (red)
- 003D 12‑Volt battery
0052 Power steering
R if the brake pedal already starts to pul-
sate just after towing begins
R if you have to transport the vehicle over
long distances
X Switch off the tow‑away protection* and
interior motion sensor* (Y page 50). Emergency towing
When circumstances do not permit the rec-
ommended 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 tow-
ing method can be employed. G
WARNING
If circumstances require towing the vehi-
cle with all wheels on the ground, always tow
with a tow bar if:
R the drive system will not run
R there is a malfunction in the brake sys-
tem
R there is a malfunction in the power sup-
ply or in the vehicle’s electrical system Towing
