Important Safety Notes - SMART 2016 fortwo Owner's Manual

Checking tire pressures manually
To determine and set the correct tire pres-
sure, proceed as follows:
Remove the valve cap of the tire that is to be
X
checked.
Press the tire pressure gauge securely onto
X
the valve.
Read the tire pressure and compare it with
X
the recommended value on the Tire and
Loading Information placard (
If the tire pressure is too low increase the
X
tire pressure to the recommended value.
If the tire pressure is too high, release
X
air. To do this, press down the metal pin in
the valve using the tip of a pen, for exam-
ple. Then check the tire pressure again
using the tire pressure checker.
Screw the valve cap onto the valve.

Repeat these steps for the other tires.

General notes
i
This function is only available in the
USA.
If a tire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire
pressure monitor only functions if the cor-
responding sensors are fitted to all wheels.

WARNING
Each tire, including the spare (if provi-
ded), should be checked at least once every
two weeks when cold and inflated to the
pressure recommended by the vehicle man-
ufacturer on the Tire and Loading Informa-
tion placard on the driver's door B-pillar
or the tire pressure label on the inside of
the fuel filler flap. If your vehicle has
tires of a different size than the size indi-
cated on the Tire and Loading Information
placard or, if available, the tire pressure
label, you should determine the proper tire
pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure moni-
toring system (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale lights up, you should stop and
page 174).
Y
check your tires as soon as possible, and
inflate them to the proper pressure. Driv-
ing on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle's handling and stopping abil-
ity. Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it
is the driver's responsibility to maintain
correct tire pressure, even if underinfla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
warning lamp will flash for approximately
a minute and then remain continuously
illuminated. This sequence will be repea-
ted every time the vehicle is started as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
