>> Practical hints. If the tire inflation pressure in the respective
tire(s) has (have) been corrected, the combi

nation low tire pressure/TPMS malfunction
telltale goes out after a few minutes of driv

ing. See also "Restarting the TPMS"
(

page 194).
Flashes 60 seconds and then stays
illuminated:
• when there is a malfunction in the TPMS.
>Have the TPMS checked at an authorized
smart center.
After the malfunction has been remedied the
combination low tire pressure/TPMS mal

function telltale goes out after a few minutes
of driving.
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 on the driver’s door
B
Pillar (

page 185) . 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.

Coolant temperature warning lamp
Illuminates:
• when the ignition is switched on.
The warning lamp goes out if the engine is
running.
• if the coolant is too hot.
>Stop the vehicle immediately in a safe
location.
>Do not continue to drive.
>Turn off the engine.
>Set the parking brake when leaving the
vehicle.
>Contact Roadside Assistance or an autho

rized smart center.If the coolant level has fallen below the
marking bar on the coolant reservoir
(

page 178):
>Add coolant as required.
>Have the coolant system checked for leaks
at an authorized smart center.
!
Among other possible causes, the
poly
V
belt could be broken. Do not continue
to drive. Otherwise, the engine will overheat
due to an inoperative water pump which may
result in damage to the engine.
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.
G
Warning!
Driving when your engine is overheated
can cause some fluids, which may have
leaked into the engine compartment, to
catch fire. You could be seriously burned.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until
the engine has cooled down.

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

No malfunction detected. The supplemental
restraint system is operational.
Scenario 2:
The SRS indicator lamp goes out after a maxi

mum of 4 seconds for approximately 1 second,
then it comes on again and stays on:
There is a malfunction in the supplemental
restraint systems. The air bags or Emer

plies particularly to children.
>Have the system checked at an authorized
smart center.
!
If the SRS indicator lamp comes on while
driving, have the system checked at an autho

rized smart center immediately.
It is possible that the air bag and the emer

gency tensioning device could be activated
unintentionally or will not function in the event
of an accident.Turn signal indicator lamp(s)
