WARNING
It is the driver’s responsibility to cali-
brate the TPMS on the recommended cold
inflation pressure. Underinflated tires
affect the ability to steer or brake and
might cause you to lose control of the vehi- cle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a
new level (e.g. because of different load or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
X Using the Tire and Loading Information
placard on the driver’s door B‑pillar
(Y page 133), make sure the tire infla-
tion pressure of all four tires is correct.
i Restart the TPMS after adjusting the
tire inflation pressure to the inflation
pressure recommended for the vehicle
operating condition. Tire pressure
should only be adjusted on cold tires.
Observe the recommended tire inflation
pressure on the Tire and Loading Infor-
mation placard on the driver’s door
B‑pillar (Y page 133). X

WARNING
Each tire should be checked monthly when cold and inflated to the inflation pressure rec-
ommended by the vehicle manufacturer on the Tire and Loading Information placard. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Infor- mation 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 illuminates a low tire pressure telltale when one or more of your tires is
significantly underinflated. 164
Display messages>> Practical hints.
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 efficiency 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 subsequent 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 variety of reasons, including the installation of incom-
patible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale 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. Display messages Possible causes/consequences and

with the vehicle’s tires, switch on the haz-
ard warning flasher, carefully slow down
and exit the roadway in a cautious manner.
X Park the vehicle at a safe distance from
moving traffic on a hard, flat surface
when possible.
X Make sure the tire valve of the damaged
tire is located below the horizontal axle
of the wheel hub.
X Engage the parking brake.
X Turn the steering wheel so that the front
wheels are in a straight ahead position.
X Move the gear selector lever to park
position P.
X Switch off the drive system.

safe distance from the roadway. Using the tire repair kit
! Depending on the type of damage on the
tire, the tire sealant could damage the
sensor of the Tire Pressure Monitoring
System (TPMS)*. Such damage is not cov-
ered by the smart Limited Warranty.
When having the damaged tire replaced,
also have the TPMS sensors* checked for
proper function. When the sensor is dam-
aged, the TPMS* will not function prop-
erly. The sensor must then be replaced at an authorized electric drive smart cen-
ter as soon as possible.

Notes on the vehicle’s electrical sys-
tem
The vehicle’s electrical system provides
power for the electric drive and all elec-
trical consumers or components of the
vehicle.
Power is supplied to the vehicle via two
batteries:
R 12-volt battery
R High-voltage battery Notes on the 12‑volt battery
Your vehicle’s 12‑volt battery is located in
the passenger footwell below the footrest
(Y page 199).
The 12 volt battery should always be suffi-
ciently charged in order to achieve its
rated service life. Refer to the Scheduled
Maintenance Guide (USA only) or the Ser-
vice booklet (Canada only) for battery
maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the
12 volt battery charge checked more fre-
quently.
When replacing the battery, always use bat-
teries approved by smart. For information,
contact an authorized electric drive smart
center. If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized electric drive smart center
about steps you need to observe. G
