Tires and wheels
Safety notes
Contact an authorized electric drive smart
center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase. G
WARNING
Replace rims or tires with the same
designation, manufacturer and type as
shown on the original part. For further
information contact an authorized electric
drive smart center. If incorrectly sized
rims and tires are mounted, the wheel
brakes or suspension components can be
damaged. Also, the operating clearance of
the wheels and the tires may no longer be
correct. G
WARNING
Worn, old tires can cause accidents. If the
tire tread is worn to minimum tread depth,
or if the tires have sustained damage,
replace them.
When replacing rims, only use genuine
smart wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly
an accident.
Retreaded tires are not tested or
recommended by smart, since previous
damage cannot always be recognized on
retreads. The operating safety of the
vehicle cannot be assured when such tires
are used. G
WARNING
If you feel a sudden significant vibration
or ride disturbance, or you suspect that
possible damage to your vehicle has
occurred, you should turn on the hazard
warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the road. Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest authorized electric drive smart
center or tire dealer for repairs.
G
WARNING
Do not drive with a flat tire. A flat tire
affects the ability to steer or brake the
vehicle. You could lose control of the
vehicle. Continued driving with aflat tire
or driving at high speed with a flat tire
will cause excessive heat build-up and
possibly a fire.
Modifications to the brake system and
wheels and the use of brake dust rings are
not permissible. Important guidelines
R Only use sets of tires and rims of the same
type and make.
R Tires must be of the correct size for the
rim.
R Break in new tires for approximately
60 miles (100 km) at moderate speeds.
R Regularly check the tires and rims for
damage. Dented or bent rims can cause
tire pressure loss and damage to the tire
beads.
R If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.
R Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths of less
than 1
/ 8 in (3 mm). Recommended tire inflation pressure
G
WARNING
Follow recommended tire inflation
pressures. 122

About towing
This section offers information on towing
methods for breakdown situations and
emergency towing. Recommended towing method -
Breakdown 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
appropriate wheel lift/dolly equipment.
Always have your vehicle transported:
R when the 0002warning lamp for the high-
voltage system lights up in the
instrument cluster
R when the Do not tow (away) message
appears in the instrument cluster
R when the multifunction display is
inoperative R
when one or several of the following
warning lamps light up:
-0001 Drive diagnostics (red)
- 0004 12‑Volt battery
0002 Power steering
R if the brake pedal already starts to
pulsate 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 47). 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. 196

G
WARNING
If circumstances require towing the
vehicle 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
system
R there is a malfunction in the power
supply or in the vehicle’s electrical
system
At ow 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 Nand the
ignition is switched on. G
WARNING
With the drive system inactive, 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.
! The vehicle may be towed only for
distances up to 30 miles (50 km) and at a
speed not to exceed 30 mph (50 km/h).
Otherwise, the electric drive or the
high-voltage system could be damaged.
! Do not tow other vehicles.
Otherwise, the drive system or
components of the high-voltage system
could be damaged.
! 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 cause damage to the supports if towing
on a bumpy road.
R Towing the vehicle should only be done
using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope, or tow rod to the vehicle chassis,
frame, or suspension parts.
! Make sure the gear selector lever is in
neutral position Nwhile towing the
