i
If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a malfunc

tion using the TPMS telltale flashing and illu

mination sequence.
The telltale extinguishes after a few minutes
driving if the malfunction has been corrected.
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 in

dicated on the Tire and Loading Informa

tion 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 illumi

nates 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 effi

ciency 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.
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 combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon subse

quent vehicle start
ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a vari

ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that pre

vent the TPMS from functioning properly.
Always check the TPMS malfunction tell

tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

>The combination low tire pressure/TPMS
malfunction telltale in the instrument
cluster (

page 34) flashes for approxi

mately 5 seconds and then goes out.
After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s specified
range. Afterwards the current tire inflation
pressures are accepted as reference
pressures and then monitored.Potential problems associated with
underinflated and overinflated tires
Underinflated tires
Underinflated tires can:
• cause excessive and uneven tire wear
• adversely affect fuel economy
• lead to tire failure from being overheated
• adversely affect handling characteristicsOverinflated tires
Overinflated tires can:
• adversely affect handling characteristics
• cause uneven tire wear
• be more prone to damage from road
hazards
• adversely affect ride comfort
• increase stopping distance
G
Warning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ

omy, and are more likely to fail from being
overheated.
G
Warning!
Follow recommended tire inflation
pressures.
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.

check).
G
Warning!
If the SRS indicator lamp does not come
on when you switch on the ignition or does
not go out again after a few seconds once
the engine is running or comes on again,
the supplemental restraint systems are
malfunctioning.
In the event that a malfunction of the SRS
is indicated as described in scenario 2,
the SRS may not be operational. For your
safety, we strongly recommend that you
contact an authorized smart center im

mediately to have the system checked; A
malfunctioning SRS system may not de

ploy when needed in an accident result

ing in serious or fatal injury, or it might
deploy unexpectedly and unnecessarily
which could result in an accident and/or
injury to you or to others

i
The vehicle&#39;s battery is drained by use of
the electric air pump. You should therefore
keep the engine running
in the open air

while inflating the tire.
>PressI on electric air pump switch
7.
The electric air pump is switched on and
inflates the tire.
i
First, the sealant is pumped into the tire.
The pressure may briefly increase to a high
value. This is normal and not an indication of a
malfunction. Do not switch off the electric air
pump.>Let the electric air pump inflate the tire for
a maximum of ten minutes.
Pressure gauge
2 must display at least
26 psi (1.8 bar) is reached. The filler hose
can become hot during inflation.
Please exercise appropriate caution.
!
Do not operate the electric air pump
longer than ten minutes without interruption.
Otherwise it may overheat.
You may operate the electrical air pump again
after it has cooled off.
>If the tire inflation pressure of at least
26 psi (1.8 bar) is not attained, turn off the
electric air pump by pressing0 on electric
air pump switch
7.
>Unscrew the end of filler hose
4
from the
tire valve.
>After clearing the area around the vehicle
of people and obstacles, drive vehicle back
or forth very slowly approximately 30 ft
(10 m).
This serves to better distribute the tire
sealant material inside the tire.>Screw the end of filler hose
4 onto the tire
valve.
>Inflate the tire again.
>After attaining a tire inflation pressure of
26 psi (1.8 bar), press0 on electric air
pump switch
7.
The electric air pump is switched off.
>Turn the key in the starter switch to
position0.
G
Warning!
If a tire inflation pressure of 26 psi
(1.8 bar) is not attained, the tire is too
severely damaged for the tire sealant to
provide a reliable tire repair.
In this case, the tire sealant cannot
properly seal the tire.
Do not drive the vehicle.
Contact the nearest smart center for as

sistance or call Roadside Assistance.
