Driving safety systems
Introduction
This section contains information about the
following driving safety systems:
RABS (Antilock Brake System)
RBAS (Brake Assist System)
RESP® (Electronic Stability Program)
RElectro-hydraulic brake system
iIn winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.

as specified in the “Technical data” section
of this Operator’s Manual.
iThe Distronic system and cruise control
switch off automatically when the ESP®
engages.
Electronic Traction System (ETS)
GObserve Safety notes, see page 55.
The ETS (Electronic Traction System) is a
component of the ESP®. The ETS improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
When you switch off the ESP®, the ETS is still
enabled.
Switching the ESP® off or on (except
SL 63 AMG)
GWarning!
The ESP® should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP® when a spare
wheel is mounted.
To improve the vehicle’s traction, switch off
the ESP®. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
Rwhen driving with snow chains
Rin deep snow
Rin sand or gravel
GWarning!
Switch on the ESP® immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP® will not
stabilize the vehicle when it is starting to skid
or a wheel is spinning.
When you switch off the ESP®,
Rthe ESP® will not stabilize the vehicle
Rthe engine output is not limited, which
allows the drive wheels to spin and thus cut
into surfaces for better grip
Rthe ETS will still apply the brakes to a
spinning wheel
Rthe ESP® continues to operate when you
are braking
Rthe cruise control or the Distronic system
cannot be activated
Rthe cruise control or the Distronic system
switch off if activated
iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ABS/
ESP® warning lamp ÷ or d8 in the
instrument cluster flashes. However, the
ESP® will then not stabilize the vehicle.
Depending on vehicle production date, the
symbol on the ESP® switch may differ.
Version 1
XSwitching off: With the engine running,
press ESP® switch : until the ESP® OFF8Depending on vehicle production date.Driving safety systems57Safety and security230_AKB; 6; 22, en-USd2ureepe,Version: 2.11.8.12009-07-28T18:49:58+02:00 - Seite 57Z
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch on the SPORT handling mode.
Do not switch on the SPORT handling mode
when a spare wheel is mounted.
To improve the vehicle’s traction, switch on
the SPORT handling mode. This allows the
drive wheels to spin and thus cut into
surfaces for better grip, for example
Rwhen driving with snow chains
Rin deep snow
Rin sand or gravel
GWarning!
Switch off the SPORT handling mode and
switch on the ESP® immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the SPORT handling
mode will only stabilize the vehicle to a limited
extent when it is starting to skid or a wheel is
spinning.
When you switch on the SPORT handling
mode
Rthe ESP® stabilizes the vehicle only to a
limited extent
Rthe engine output is limited, but only to the
extent that allows the drive wheels to spin
and thus cut into surfaces for better grip
Rthe ETS will still apply the brakes to a
spinning wheel
Rthe ESP® continues to operate when you
are braking hard
Rthe cruise control or the Distronic system
cannot be activated
Rthe cruise control or the Distronic system
switch off if activated
iWhen the SPORT handling mode is
switched on and one or more drive wheels
are spinning, the ABS/ESP® warning lamp
÷ or d8 in the instrument cluster
flashes. However, the ESP® will then
stabilize the vehicle only to a limited extent.
Depending on vehicle production date, the
symbol on the ESP® switch may differ.
Version 1
XSwitching on: With the engine running,
press ESP® switch : briefly.
The SPORT handling mode warning lamp
in the instrument cluster comes on.
The message SPORT handling mode
appears in the multifunction display.
XSwitching off: With the engine running,
press ESP® switch : briefly.
The SPORT handling mode warning lamp
in the instrument cluster goes out.

XSwitching off: With the engine running,
press ESP® SPORT switch : briefly.
The ABS/ESP® warning lamp d in the
instrument cluster goes out. The message
ESP-ON appears in the multifunction
display.
The SPORT handling mode switches off
automatically when you turn off the engine.
When starting the engine, the ESP® is
activated automatically.
Switching the ESP® off or on
GWarning!
The ESP® should not be switched off during
normal driving.
Disabling of the system will result in the
following:
Rno restriction to engine torque
Rloss of system-supported traction control
“ESP® OFF” is designed for driving on closed
tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and experienced
driver able to handle these critical driving
situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch off the ESP®.
Do not switch off the ESP® when a spare

The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed. With
increasing speed, the ride height is reduced
by up to approximately 0.5 in (12 mm). With
decreasing speed, the ride height is again
raised to the selected vehicle level.
These height adjustments are so small that
you may not notice any change.
Setting the vehicle level
GWarning!
To help avoid personal injury, keep hands and
feet away from wheel housing area, and stay
away from under the vehicle when lowering
the vehicle chassis.
The following vehicle level settings can be
selected when the vehicle is stationary and
the engine is running:
LevelUse forIndicator

is on.
Level 2For driving on very
rough road surface
conditions.
Both lamps
are on.
Select the level 1 and level 2 settings only
when required by current driving conditions.
Otherwise the fuel consumption may
increase and/or the handling may be
impaired.
iThe selected setting remains stored in
