▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Display in the following situations:
▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, 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 illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. 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 pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency 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 under-inflation 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 indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function 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 variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicleSeite 101SafetyControls101

HintsDo not perform any work on the lighting
system
Have any work on the lighting system, includ‐
ing bulb replacement, performed only by a
service center. Due to the high voltage present
in the system, there is a danger of fatal injuries
if work is carried out improperly.◀
Irritation of the retina
Never look directly into the headlights or
their light sources for a lengthy period of time,
otherwise this could irritate your retinas.◀
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀
Changing wheels
Hints
When sealants are used, an immediate wheel
change when there is a loss of tire inflation
pressure in the event of a flat tire is unneces‐
sary.
Which is why no spare tire is available.
The tools for changing wheels are available as
accessories from your service center.
Jacking points for the vehicle jack
The jacking points for the vehicle jack are lo‐
cated at the positions shown.
Vehicle battery
The vehicle battery has 12 volts. The battery
supplies the onboard electronics with energy.
Information about the high-voltage system, re‐
fer to page 150.
Maintenance
The battery is maintenance-free.
The added amount of acid is sufficient for the
service life of the battery.
Further information about the battery can be
obtained from your service center.
Battery replacement Use approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery
registered on the vehicle by the service center
to ensure that all comfort features are fully
available and that any Check Control mes‐
sages of these comfort features are no longer
displayed.
Charge vehicle battery Do not use any charging devices
Do not charge the vehicle battery with an
external charging device; otherwise, there is a
risk of property damage, e. g., to the vehicle's
electronics.◀
Charging a discharged battery, refer to
page 156.
Power failure
After a temporary power loss, some equipment
needs to be newly initialized or individual set‐
tings updated, e. g.:▷Time: update.Seite 181Replacing componentsMobility181
