Possible causes/consequences and P Solutions
Check Tire Pres‐
sure Soon Canada only:
The tire pressure loss warning system has detected a significant
loss in pressure.
A warning tone also sounds.
Possible causes: R
you have changed the positions of the wheels and tires or instal-
led new wheels and tires. R
the tire pressure in one or more tires has dropped
G WARNING
Tire pressures that are too low pose the following hazards: R
they may burst, especially as the load and vehicle speed
increase. R
they may wear excessively and/or unevenly, which may greatly
impair tire traction. R
the driving characteristics, as well as steering and braking, may
be greatly impaired.
There is a risk of an accident. X
Stop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so. X
Secure the vehicle against rolling away ( Y
page 169).X
Check the tires and, if necessary, follow the instructions for a
flat tire ( Y
page 310). X
Check the tire pressures and, if necessary, correct the tire pres-
sure. X
Restart the tire pressure loss warning system when the tire
pressure is correct ( Y
page 336).
Check Tire Pres‐
sure Then Restart
Run Flat Indicator Canada only:
The tire pressure loss warning system generated a display mes-
sage and has not been restarted since. X
Set the correct tire pressure in all four tires. X

Problem
Possible causes/consequences and P Solutions
%
The yellow ABS warning
lamp is lit while the
engine is running. ABS (Anti-lock Braking System) is deactivated due to a malfunc-
tion. Therefore, BAS (Brake Assist), COLLISION PREVENTION
ASSIST PLUS, ESP ®
(Electronic Stability Program), the HOLD func-
tion and hill start assist are also deactivated, for example.
ATTENTION ASSIST is deactivated.
G WARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP ®
is not operational, ESP ®
is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident. X
Observe the additional display messages in the multifunction
display. X
Drive on carefully. X
Visit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic trans-
mission, will not be available.Warning and indicator lamps in the instrument cluster 261
