ESP
®
(Electronic Stability Program)
General notes
i
Observe the "Important safety notes" sec-
tion (
Y
page 71).
ESP
®
monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®
assists the driver when
pulling away on wet or slippery roads. ESP
®
can also stabilize the vehicle during braking.
ETS (Electronic Traction System)
i
Observe the "Important safety notes" sec-
tion (
Y
page 71).
ETS traction control is part of ESP
®
.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP
®
.
i
AMG vehicles: your vehicle may be
equipped with 20-inch tires on the rear
axle. If replaced with a 19-inch tire, ETS
may intervene noticeably sooner for the
first few kilometers. After approximately
10 km ETS will function as usual again.
Information on the dimensions and types of
wheels and tires for your vehicle can be
found in the "Wheel/tire combinations"
section (
Y
page 593).
Important safety notes
G
WARNING
If ESP
®
is malfunctioning, ESP
®
is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®
checked at a
qualified specialist workshop.
!
When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by ESP
®
may otherwise destroy the brake system.
When towing the vehicle with the rear axle
raised, observe the notes on
ESP
®
(
Y
page 561).
ESP
®
is deactivated if the å warning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the å warn-
ing lamp are lit continuously, ESP
®
is not
available due to a malfunction.
Observe the information on warning lamps
(
Y
page 273) and display messages which
may be shown in the instrument cluster
(
Y
page 240).
i
Only use wheels with the recommended
tire sizes. Only then will ESP
®
function
properly.
