the initial wipe, pauses between wipes
are automatically controlled by the rain
sensor.
!Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.

83 Safety and Security
Driving and safety systems
4-ETS
The 4-ETS improves vehicle’s ability to uti-
lize available traction, especially under
slippery road conditions. The brakes are
applied to the spinning wheel and power is
allowed to flow to the wheel(s) with trac-
tion.
The 4-ETS function is available between ve-
hicle speeds of 0 mph (km/h) and 37 mph
(60 km/h).
The ESP warning lampv in the instru-
ment cluster (
page 24) comes on when
you switch on ignition (
page 35). It goes
out when the engine is running.
The ESP warning lampv starts to flash
at any vehicle speed, as soon as the tires
lose traction and the wheels begin to spin.For more information, see “Practical hints”
(
page 293).
Warning!
G
When you see the ESP warning lamp
v

flashing in the instrument cluster, then pro-
ceed as follows:


While driving off, apply as little throttle
as possible.


While driving ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4-ETS cannot prevent accidents result-
ing from excessive speed.
!The engine must be shut off when

the parking brake is being tested on
a brake test dynamometer.


the vehicle is being towed with one
axle raised.
Otherwise, the 4-ETS will engage the
brakes and seriously damage the brake
system.

84 Safety and SecurityDriving and safety systemsEBB
The EBB enhances braking effectiveness
by allowing the rear brakes to supply a
greater proportion of the braking effort in
straight line braking circumstances with-
out a loss of vehicle stability.
ESP
The Electronic Stability Program (ESP)
monitors the vehicle’s traction (force of ad-
hesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle.
The ESP warning lampv in the instru-
ment cluster (
page 24) flashes when the
ESP is engaged.
The ESP warning lampv comes on
when you switch on ignition (
page 35). It
goes out when the engine is running.
