Power meter  V
alid for: hybrid vehicles Fig. 65
Digital instrument panel: Power meter The lower left hand side of the rev counter
has tw
o col
our coded areas:
Charge: Charging zone. Indicates the
amount of charge generated and the
maximum charge.
Power %: Electric traction zone. Indi-
cates the percentage of power used and
the maximum amount of power currently
available.
The power meter shows the usage level of
the electric drive. The power meter bar shows
the current usage level. Green
Blue A finer coloured border indicates how much
the propul

sion can currently be used. De-
pending on the selected driving program and
the current availability of electrical power,
the boundaries of the different colours can
vary.
The following displays can be seen on the
Power meter:

Braking and parking
Brake assist systems Electronic Stability Control (ESC)
The ESC helps t
o impr
ove safety. It reduces
the tendency to skid and improves the stabili-
ty and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening !.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (TCS), electronic dif-
ferential lock (EDS), electronic torque control
(XDS) and the tractor-trailer sway mitiga-
tion*.
ESC also helps stabilise the vehicle by
changing the torque.
The TCS can be deactivated when wheel
spin is desirable ››› page 281
.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer the
vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal
pulsate while the ABS is working. If the running gear or brake system is modi-
fied, the eff
ectiv

eness of the ABS could be se-
verely limited.
Hydraulic Brake Assist (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control (TCS)
In the event of the wheels spinning, the TCS
reduces the engine torque to adapt to the
road condition. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch on
again automatically when the brake has
cooled down. Tractor-trailer sway mitigation*
If the vehicl
e is pulling a trailer, it will control
the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries ››› page 303
.
Electronic engine torque management
(XDS)
When taking a curve, the driveshaft differen-
tial allows the outer wheel to turn at a higher
speed than the inner wheel. In this way, the
wheel that is turning faster (outer wheel) re-
ceives less drive torque than the inner wheel.
This may mean that in certain situations the
torque delivered to the inner wheel is too
high, causing the wheels to spin. On the other
hand, the outer wheel is receiving a lower
drive torque than it could transmit. This can
cause a loss of grip on the drive axle, in this
case the front axle, which results in under-
steer or “lengthening” of the trajectory.
The XDS can detect and correct this effect
via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the requested
trajectory is much more precise. »
