the Tire Pressure Monitor may not have
been reset. In this case, perform the reset.
Possible driving range with a
depressurized tire
The possible driving range varies depending
on the how the vehicle is loaded and used, e.g.,
speed, road conditions, external temperature.
The driving range may be less but may also be
more if an economical driving style is used.
If the vehicle is loaded with an average weight
and used under favorable conditions, its possi‐
ble driving range will be up to 50 miles/80 km.
Vehicle handling with damaged tires
Vehicles driven with a damaged tire will handle
differently, potentially leading to conditions
such as the following:
▷
Greater likelihood of swerving off course
▷
Longer braking distances
▷
Changed self-steering properties
Adjust driving style. Avoid abrupt steering ma‐
neuvers or driving over obstacles, for instance
curbs, potholes, etc.
System limits
Temperature
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 in‐
flation pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Following a temperature-related warning, the
target pressures are displayed on the Control
Display again after a short distance.
Sudden tire pressure loss
The system cannot indicate sudden serious
tire damage caused by external circumstances.
Failure to perform a reset
Tires with special approval: the system will not
function correctly if a reset was not performed,
for example a flat tire may be indicated al‐
though the tire inflation pressures are correct.
Malfunction
The yellow warning light flashes and is
then illuminated continuously. A Check
Control message is displayed. It may
not be possible to identify tire pressure losses.
In these cases:
▷
A wheel without TPM electronics, such as
an emergency wheel, is mounted: have the
wheels checked, if needed.
▷
Malfunction: have the system checked.
▷
Interference caused by systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.
▷
For tires with special approval: the system
was unable to complete the reset. Reset
the system 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‐
