Auxiliary power outlet
The auxiliary power outlet supplies power
to the following electrical accessories
when the key is turned to starter switch
position 1:
R the electric air pump, available in con-
junction with the tire repair kit*
R other consumers which operate up to a
maximum of 60 W
! The auxiliary power outlet can accom-
modate 12V DC electrical accessories
designed for use with the standard “cig-
arette lighter” plug type.

ommended rims and tires for summer and
winter operation. They can also offer
advice concerning tire service and pur-
chase. G
WARNING
Replace rims or tires with the same desig-
nation, 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 suspen-
sion 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 partic-
ular rim type. Failure to do so can result in
the bolts loosening and possibly an acci-
dent.
Retreaded tires are not tested or recom-
mended 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 occur-
red, you should turn on the hazard warning
flashers, carefully slow down, and drive
with caution to an area which is a safe dis-
tance 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 vehi-
cle. Continued driving with a flat 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 pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption of the vehicle, and are more
likely to fail from being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and 128

General:
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation. No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designa-
tion: Light Truck tire based on U.S. design
standards.
Letter “T” preceding the size designation:
Temporary spare tires which are high pres-
sure compact spares designed for tempo-
rary emergency use only.
Tire width
Tire width 0043indicates the nominal tire
width in mm.
Aspect ratio
Aspect ratio 0044is the dimensional rela-
tionship between tire section height and
section width and is expressed as a per-
centage. The aspect ratio is arrived at by
dividing section height by section width.
Tire code
Tire code 0087indicates the tire construc-
tion type. The “R” stands for radial tire
type. Letter “D” means diagonal or bias ply
construction; letter “B” means belted-bias
ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire
speed rating” (Y page 141).
Rim diameter
Rim diameter 0085is the diameter of the
bead seat, not the diameter of the rim edge.
Rim diameter is indicated in inches (in).

WARNING
The tire load rating must always be at least
half of the GAWR of your vehicle. Otherwise, 140

tire failure may result and cause an acci-
dent and/or serious personal injury to you
or others.
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part. G
WARNING
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.
Tire load rating 0083is a numerical code
associated with the maximum load a tire
can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load” (Y page 136)
where the maximum load associated with
the load index is indicated in kilograms
and lbs.
For additional information on tire load
rating, see “Load identification”
(Y page 142).
Tire speed rating G
WARNING
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
Regardless of the tire speed rating, local
speed limits should be obeyed. Use prudent
driving speeds appropriate to prevailing
conditions. Tire speed rating
0084indicates the
approved maximum speed for the tire.
Summer tires Index Speed rating
Q up to 100 mph (160 km/h)
R up to 106 mph (170 km/h)
S up to 112 mph (180 km/h)
T up to 118 mph (190 km/h)
H up to 130 mph (210 km/h)
V up to 149 mph (240 km/h)

R
At the tire manufacturer’s option, any
tire with a speed capability above
149 mph (240 km/h) can include a “ZR” in
the size designation (for example:
245/40 ZR18). To determine the maximum
speed capability of the tire, the service
description for the tire must be referred
to.
The service description is comprised of
tire load rating 0083and tire speed rating
0084.
If your tire includes “ZR” in the size
designation and no service description
is given, the tire manufacturer must be
consulted for the maximum speed capa-
bility.
If a service description is given, the
speed capability is limited by the speed
symbol in the service description.
Example: 245/40 ZR18 97Y.
In this example, “97Y” is the service
description. The letter “Y” designates
the speed rating and the speed capabil- Tires and wheels

Preparing the vehicle
Upon experiencing any type of problem
with the vehicle’s tires, switch on the haz-
ard warning flasher, carefully slow down
and exit the roadway in a cautious manner.
X Park the vehicle at a safe distance from
moving traffic on a hard, flat surface
when possible.
X Make sure the tire valve of the damaged
tire is located below the horizontal axle
of the wheel hub.
X Engage the parking brake.
X Turn the steering wheel so that the front
wheels are in a straight ahead position.
X Move the gear selector lever to park
position P.
X Switch off the drive system.
X Remove the key from the starter switch
and take the key with you.
i Open door only when conditions are safe
to do so.
X Have any passenger exit the vehicle at a
safe distance from the roadway. Using the tire repair kit
! Depending on the type of damage on the
tire, the tire sealant could damage the
sensor of the Tire Pressure Monitoring
System (TPMS)*. Such damage is not cov-
ered by the smart Limited Warranty.
When having the damaged tire replaced,
also have the TPMS sensors* checked for
proper function. When the sensor is dam-
aged, the TPMS* will not function prop-
erly. The sensor must then be replaced at
an authorized electric drive smart
center as soon as possible.
i Depending on production date of your
vehicle, it will be equipped with version
1 or version 2 of the tire repair kit.
