Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al
lows more precise driving in curves . Th e applica
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc
t ion in engine power.
- You may hear noises when the systems de scribed are working.
ESC turns on automatically when you start the engine .

The following situations are exceptions where it may be useful to switch on sport mode to allow
the wheels to spin:

A WARNING -
You should only switch sport mode on or
sw itch ESC/ASR off if your driving ab ilities and
road conditions permit.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could spin and the vehicle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are sw itched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on when cr uise
control or adaptive cruise control* is switch
ed on.
- Malfunctions in the rear spoiler may make it
i mpossible to switch the ESC/ASR off or to
switch sport mode on.
Rear spoiler
Applies to vehicles: with retractable rear spoiler
The rear spoiler improves vehicle handling and
enhances driver control.

Automatic mode (normal operation)
-Extends automatically: when the vehicle speed
exceeds approx imately 75 mph (120 km/h).
- Retracts automatically: when the vehicle speed
drops below approx imately 50 mph (80 km/h).
Manual mode
- Manual deployment: Tapping briefly on the
switch ~ fig. 154 deploys the rear spoiler.
