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.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
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.
Your vehicle is equipped with the Tire and
Loading Information placard located on
the driver’s door B‑pillar ( Y page 130).
The tire inflation pressure should be
checked regularly. Only adjust the tire
inflation pressure on cold tires. The tires
can be considered cold if the vehicle has
been parked for at least 3 hours or driven
less than 1 mile (1.6 km). Depending on the
ambient temperature, the driving speed
and the tire load, the tire temperature
changes. When the tire temperature changes by 18¦ (10¥), the tire inflation
pressure will change by approximately
10 kpa (0.1 bar, 1.5 psi). Keep this in mind
when checking tire inflation pressure on
warm tires and adjust the tire pressure
only if the tire inflation pressure is too
low for the current operating conditions.
If you check the tire inflation pressure
when the tires are warm, the reading will
be higher than the cold reading. This is
normal. Do not let air out to match the
specified cold tire inflation pressure.
Otherwise, the tire will be underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B‑pillar.
Keeping the tires properly inflated
provides the best handling, tread life and
riding comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B‑pillar, also consult the tire inflation
pressure
label (if available) on the inside
of the filler flap for any additional
information pertaining to special driving
situations. For more information, see
“Important notes on tire inflation
pressure” ( Y page 126).

The traction grades, from highest to
lowest, are AA, A, B, and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature
G
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or in
combination, can cause excessive heat
build-up and possible tire failure.
The
temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel. Sustained
high temperature can cause the material of
the tire to degenerate and reduce tire life,
and excessive temperature can lead to
sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law. Rotating tires
G
WARNING
Do not rotate front and rear wheels as they
have different dimensions, e.g. rim size,
wheel offset etc. Otherwise, the handling
can be affected and you could endanger
yourself and others. Thoroughly clean the mounting face of the
wheels
and brake discs, i.e. the inner side
of the wheels/tires each time the wheels/
tires are changed. Check for and ensure
proper tire inflation pressure. G
WARNING
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
81 lb‑ft (110 Nm).
Only use genuine smart wheel bolts
specified for your vehicle’s rims.
For
information on wheel change, see “Flat

For safety reasons, smart recommends
that you only use snow chains that have
been approved by smart.
Information
on this is available from any
smart center.
Please refer to the separate operating
instructions for detailed information on
mounting the snow chains.
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
Please observe the following guidelines
when using snow chains:
R Using snow chains is not permissible
with all wheel/tire combinations
(Y page 217).
R Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
R Use of snow chains may be prohibited
depending on location. Always check
local and state laws before mounting
snow chains. G
WARNING
When mounting or removing snow chains,
always park your vehicle on level ground,
engage the parking brake, and turn off the
engine. The vehicle could otherwise move
and injure yourself or other road users. G
WARNING
When mounting and removing snow chains,
ensure that you and your vehicle are at a
safe distance from moving traffic. Not
doing
so could endanger other road users or
even lead to you being injured by the
vehicles behind you. G
WARNING
The vehicle’s handling changes when
driving with snow chains on any kind of
road surface. This means that you should always adapt your driving style to suit the
current road and weather conditions.
! If snow chains that do not meet
requirements are mounted, they may
scrape against the body or axle
components when the vehicle is in
motion. This could result in damage to
the rim/tire or vehicle. Driving instructions

Check
Tire Pressure The tire inflation pressure in at least one tire is
significantly below the reference value.
X
Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers.
X Check and adjust tire inflation pressure as required
(Y page 126).
X If necessary, change the wheel ( Y page 194).G
WARNING
Each tire should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the Tire and Loading Information placard. If
your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, you should determine the proper tire inflation pressure for those
tires.
As
an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly underinflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even
if underinflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
