Treadwear indicators
Narrow bands, sometimes called “wear
bars” that show across the tread of a tire
when
only 1
/ 16 in (1.6 mm) of tread remains.
Uniform Tire Quality Grading Standards A tire information system that provides
consumers with ratings for a tire’s
traction, temperature and treadwear.
Ratings are determined by tire
manufacturers using U.S. government
testing

procedures. The ratings are molded
into the sidewall of the tire.
Vehicle maximum load on the tire Load on an individual tire that is
determined by distributing to each axle
its share of the maximum loaded vehicle
weight and dividing it by two.
Winter driving
Before the onset of winter, have your
vehicle winterized at an authorized smart
center.
This service includes:
R Check of anticorrosion and antifreeze
concentration.
R Addition of washer concentrate to the
water of the windshield/rear window.
Use a windshield washer concentrate
labeled for winter which is formulated
for temperatures below freezing point
(Y page 222).
R Battery

test. Battery capacity drops with
decreasing ambient temperature. A well
charged battery helps to make sure the
engine can be started, even at low
ambient temperatures.
R Tire change. Winter tires
G
WARNING
Winter tires with a tread depth of less
than 1
/ 6 in (4 mm) must be replaced. They
are no longer suitable for winter
operation.
Always use winter tires at temperatures
below 45 ¦ (7¥) and whenever wintry road
conditions

prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking i on the tire
sidewall. These tires meet specific snow
traction performance requirements of the
Rubber Manufacturers Association (RMA)
and the Rubber Association of Canada (RAC)
and have been designed specifically for
use in snow conditions. Use of winter tires
is the only way to achieve the maximum
effectiveness of the ABS and ESP ®
in winter
operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the "Technical data"
section (Y page 217).
Always observe the speed rating of the
winter tires installed on your vehicle. If
the maximum speed for which your tires are
rated is below the speed rating of your
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available at your tire
dealer or any authorized smart center. Snow chains*
! Remember

that snow chains must always
be compatible with the tire sizes of a
vehicle. Snow chains that are approved
by smart are only permitted for the
following tire size:
175/55 R15 on the rear axle. 142

Charging the battery G
WARNING
Avoid creating sparks when charging the
battery as escaping gases are flammable.
Keep

open flames away from the battery and
do not smoke.
Do not touch the battery terminal with metal
objects and do not remove the battery
charger’s terminal clamps until the battery
charger has been switched off and no
further gas is being discharged by the
batteries.
Only charge the battery in a well ventilated
area.
There is a risk of acid burns during the
charging procedure due to the gases which
escape from the battery. Do not lean over
the battery when it is being charged. G
WARNING
Never charge a battery while still installed
in the vehicle. Gases may escape during
charging and cause explosions that may
result in paint damage, corrosion or
personal injury.
X Charge battery in accordance with the
instructions of the battery charger
manufacturer.
! Only use chargers of a correct and
suitable voltage.
! Never attempt to recharge a frozen
battery. Have the battery checked at a
smart center. The battery housing could
be damaged. Reinstalling the battery X
Reinstall the charged battery. Follow the
previously described steps in reverse
order.
! The battery, its filler caps and the
ventilation

hose must always be securely
installed when the vehicle is in
operation.
Reconnecting the battery !
Always
connect the battery in the order
described below. Otherwise the
vehicle’s electronics can be damaged.
X Turn off all electrical accessories.
X Remove the key from the starter switch.
! Never invert the terminal connections!
X Connect the battery positive lead and
fasten cover ? (Y page 198).
X Connect battery negative lead =

WARNING
Failure to follow these directions will
cause
damage to the electronic components,
and can lead to a battery explosion and
severe injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.

immediately flush affected area with
water, and seek medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive.
Keep flames or sparks away from battery,
avoid improper connection of jumper
cables, smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing
personal injury.
Read all instructions before proceeding.
! Do not tow‑start vehicle. You could
otherwise seriously damage the
transmission
which is not covered by the
smart Limited Warranty.
! Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using
a battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized smart
center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any other metal part while the other end
is still attached to a battery.
If the battery is discharged, the engine can
be started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R Access to the battery is not possible on
all vehicles. If you cannot access the
battery in your vehicle provide jump start power by an external battery or
starter pack.
R Jump starting should only be performed
when the engine and catalytic converter
are cold.
R Do not start the engine if the battery is
frozen. Let the battery thaw out first.
R Only jump start from batteries with the
same
voltage rating (12 V). Jump starting
with a more powerful battery could
damage the vehicle’s electrical system.
Such damage will not be covered by the
smart Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained
completely, let the donating power
source charge the vehicle for several
minutes before reattempting the
starting process. G
WARNING
Keep flames or sparks away from battery. Do
not smoke.
