WARNING
When the ABS system is malfunctioning, the wheels may lock during hard braking, reducing steering capability and extending the braking distance.
When the ABS is switched off due to a malfunction, the ESP ®
is also switched off. The basic
driving and braking functions are still available.
The risk of your vehicle skidding is then increased in certain situations. You should
therefore always adapt your speed and driving style to the prevailing road and weather
conditions. Problem Possible causes/consequences and

WARNING
Driving with the brake warning lamp illuminated can result in an accident. Have your brake system checked immediately if the brake warning lamp stays on.
Do not add brake fluid before checking the brake system.
! If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum
mark or below, have the brake system checked for brake pad thickness and leaks imme- diately. Contact an authorized electric drive smart center immediately. Do not add

Scenario 1:
The SRS indica-

the ignition is
switched on and goes out after a

malfunction. The supplemental restraint system is opera-
tional.

Scenario 2:
The SRS indica-
tor lamp illu-

the ignition is
switched on and goes out after a
maximum of
4 seconds for
approximately
1 second, then itcomes on again
and stays on. There is a malfunction in the supplemental restraint systems.

unexpectedly or fail to deploy in an accident.
X Do not sit on the passenger seat; this applies particularly to
children.
X Have the system checked at an authorized electric drive
smart center. 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 drive system is running or comes on again, the supple-
mental 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
electric drive smart center immediately to have the system checked; A malfunctioning SRS system may not deploy when needed in an accident resulting 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.
! If the SRS indicator lamp comes on while driving, have the system checked at an
authorized electric drive smart center immediately.
It is possible that the air bag and the emergency tensioning device could be activated
unintentionally or will not function in the event of an accident.

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. What to do if ...

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.
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 increases energy consumption, reduces 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 lowtire 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. 174
