Safety and Security
Driving safety systems
The Electronic Stability Program (ESP
®
) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
®
recognizes when a wheel is
spinning or if the vehicle starts to skid. By
applying brakes to the appropriate
wheel and by limiting engine output, the
ESP
®
works to stabilize the vehicle. The
ESP
®
is especially useful while driving off
and on wet or slippery road surfaces. The
ESP
®
also stabilizes the vehicle during
braking and steering maneuvers.
The ABS/ESP
®
warning lamp v in the
instrument cluster flashes when the ESP
®
is engaged.
The ABS/ESP
®
warning lamp v in the
instrument cluster comes on when you
switch on the ignition. It goes out when
the engine is running.
! Because the ESP
®
operates automatically,
the engine must be turn off (SmartKey in
starter switch position 0 or 1 or
KEYLESS-GO** start/stop button in position 0
or 1) when
앫 the parking brake is being tested on a
brake test dynamometer
앫 the vehicle is being towed with the front/
rear axle raised.
Active braking action through the ESP
®
may
otherwise seriously damage the brake system.
i The ESP
®
will only function properly if
you use wheels of the recommended tire size
(컄 page 436).
For more information on ESP
®
, see the
“Practical hints” section (컄 page 354)
and (
컄 page 368).
Electronic traction system
The electronic traction system is a com-
ponent of the ESP
®
.
The electronic traction system improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
ESP
®
Warning! G
Never switch off the ESP
®
when you see
the ABS/ ESP
®
warning lamp v flashing
in the instrument cluster. In this case pro-
ceed as follows:
앫 While driving off, apply as little throt-
tle as possible.
앫 While driving, ease up on the accelera-
tor.
앫 Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
®
cannot prevent accidents result-
ing from excessive speed.
Warning! G
The ESP
®
cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase the traction afforded. The
ESP
®
cannot prevent accidents, including
those resulting from excessive speed in
turns, or hydroplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ESP
®
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
