Tire Pressure; Warning Message - SMART 2016 fortwo Owner's Manual

Tire pressure

or alternate Tires and wheels allow the
TPMS to continue to function properly.
It is the driver's responsibility to set the
tire pressure to that recommended for cold
tires which is suitable for the operating sit-
uation ( page 174). Note that the correct tire
Y
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor. If there is a substantial loss of
pressure, the warning threshold for the warn-
ing message is aligned to the reference val-
ues taught-in. Restart the tire pressure mon-
itor after adjusting to the cold tire pressure.
The current pressures are saved as new ref-
erence values. As a result, a warning message
will appear if the tire pressure drops sig-
nificantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
page 174).

The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers.
The tire pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indi-
cating a pressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whether a tire pressure is too low
or the tire pressure monitor is malfunction-
ing:
If the warning lamp is lit continuously, the
R
tire pressure on one or more tires is sig-
nificantly too low. The tire pressure mon-
itor is not malfunctioning.
If the warning lamp flashes for around a
R
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
i
A message appears in the display in addi-
tion to the warning lamp.
Observe the information on display mes-
sages ( page 122).
Y
If the tire pressure monitor is malfunction-
ing, it may take up to ten minutes for the tire
pressure warning lamp to inform you of the
malfunction. The malfunction will be indi-
cated first by the tire pressure warning lamp
flashing for approximately one minute and
then remaining lit. When the malfunction has
been rectified, the tire pressure warning
lamp goes out after a few minutes of driving.
The operation of the tire pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.
Tire pressure monitor warning messages
If the tire pressure monitor detects a pres-
sure loss in one or more tires, a warning mes-
sage is shown in the display. The yellow warn-
ing light in the tire pressure monitor lights
up. For certain display messages a warning
tone also sounds.
If the Correct Tire Pressure
R
appears in the display, the tire pressure in
at least one tire is too low. Correct the tire
pressure at the next opportunity.
If the Tire Pressure Warning Tire
R
Failure message appears in the display,
the tire pressure in one or more tires has
dropped suddenly and the tires must be
checked.
Observe the instructions and safety notes for
the display messages in the "Tires" section
( page 122) and the indicator and warning
Y
lamps in the instrument cluster in the "Tires"
section ( page 135).

Restarting the tire pressure monitor
When you restart the tire pressure monitor,
all existing warning messages are deleted
and the warning lamps go out. The monitor
uses the currently set tire pressures as the
reference values for monitoring. In most
cases, the tire pressure monitor will auto-
matically detect the new reference values
after you have changed the tire pressure.
However, you can also define reference values
manually as described here. The tire pres-
sure monitor then monitors the new tire pres-
sure values.
Set the tire pressure to the value recom-
X
mended for the corresponding driving sit-
uation on the Tire and Loading Information
placard on the B-pillar on the driver's side
page 174).

Additional tire pressure values for dif-
ferent loads can also be found on the tire
