You can set a maximum charge current in the
E-CELL E-CELL menu.
It is only necessary to select the maximum
charge current if there are no charge current
settings on the charging cable.

Tire Pressure Tire Pressure The tire pressure is too low in at least one of the tires, or the tire
pressure difference between the wheels is too great.
X Check the tire pressures at the next opportunity (Y page 307).
X If necessary, correct the tire pressure.
X Restart the tire pressure monitor (Y page 309).Check Tires
Check Tires The tire pressure in one or more tires has dropped significantly.
The wheel position is displayed in the multifunction display.
A warning tone also sounds.
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 153).
X Check the tires and, if necessary, follow the instructions for a
flat tire (Y page 280).
X Check the tire pressure (Y page 307).
X If necessary, correct the tire pressure. Display messages

The red brake system

yellow ABS, ESP ®
and
ESP ®
OFF warning
lamps are lit while the
drive system is running. ABS and ESP
®
are malfunctioning. Therefore, BAS, RBS, COLLI-
SION PREVENTION ASSIST PLUS, EBD, the HOLD function and hill
start assist are also unavailable, for example.
ATTENTION ASSIST is deactivated.
G WARNING
The braking performance of the electric motor using recuperative braking may be either reduced or not effective. If you do not make
an additional effort to apply the brake yourself, the braking effect may not be sufficient. If necessary, counteract the reduced regen-erative braking effect by applying the brake yourself.
The brake system continues to function normally, but without the functions listed above. The front and rear 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.
