Mercedes-Benz CL-Class 2012 - Manual (Page 67)

Beware of these limits if you deactivate
ESP
® .
Do not deactivate ESP ® when the emergency
or spare wheel is mounted.
ESP ® is activated automatically when the
engine is started.
i Vehicles with ECO start/stop function:
the ECO start/stop function switches the
engine off automatically when the vehicle
comes to a stop. The engine starts
automatically when the driver wants to pull
away again. ESP
® remains in its previously
selected status. Example: if ESP ® was
deactivated before the engine was
switched off, ESP
® remains deactivated
when the engine is switched on again.
It may be best to deactivate ESP ® in the
following situations:
R
when using snow chains
R
in deep snow
R
on sand or gravel
G WARNING
Switch on ESP ® immediately if one of the
previously stated conditions is no longer met.
Otherwise, ESP
® cannot stabilize the vehicle
if it begins to lurch or when a wheel spins.
When you deactivate ESP ® :
R ESP ® no longer improves driving stability.
R
the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R
traction control is still activated.
R ESP ® still provides support when you
brake.
If ESP ® is deactivated and one or more wheels
start to spin, the ÷ ESP ® warning lamp in
the instrument cluster flashes. In such
situations, ESP
® will not stabilize the vehicle.
X To deactivate:( Y page 342).
The å ESP ® OFF warning lamp in the
instrument cluster lights up.
G WARNING
When the å ESP ® OFF warning lamp is lit,
ESP ® is deactivated.
If the ÷ ESP ® warning lamp and the
å ESP ® OFF warning lamp remain lit,
ESP ® is not available due to a malfunction.
When ESP ® is deactivated or not operational,
vehicle stability in standard driving
maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESP
® .
! Avoid spinning the driven wheels for an
extended period with ESP ® deactivated.
You could otherwise damage the drivetrain.

The å ESP ® OFF warning lamp in the
instrument cluster goes out.
EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section ( Y page 61).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
G WARNING
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect. However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident. You should therefore adapt your
driving style to the different handling
characteristics.
