braking function. COLLISION PREVENTION
ASSIST PLUS can help you to minimize the
risk of a front-end collision with a vehicle
ahead or reduce the effects of such a
collision. If COLLISION PREVENTION ASSIST
PLUS detects that thereis a risk of a collision,
you will be warned visually and acoustically.
In critical situations COLLISION PREVENTION
ASSIST PLUS also initiates automatic
braking.
Function
XTo activate/deactivate:activate or
deactivate COLLISION PREVENTION
ASSIST PLUS in the on-board computer
(Ypage 204).
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the
symbol appears in the
assistance graphics display.
If the driver's seat belt is fastened,
COLLISION PREVENTION ASSIST PLUS can
brake automatically withinaspeed range of
between 4 mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSISTPLUS can
also react to stationary obstacles with
automatic braking within a speed range of
between 4 mph (7 km/h) and 19 mph
(30 km/h).
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radarsources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes"
section (Ypage 61).
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/4ETS (Electronic Traction System)
iObserve the "Important safety notes"
section (Ypage 61).
ETS/4ETS 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®.
Important safety notes
GWARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
Driving safety systems65
Safety
Z

Only activate SPORT handling mode in the
situations described in the following.
GWARNING
If you deactivate ESP®, ESP®no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP®in the situations
described in the following.
In the following situations, it may be better to
activate SPORT handling mode or deactivate
ESP®:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
Ron designated roads when the vehicle's
own oversteering and understeering
characteristics are desired
Driving in SPORT handling mode or without
ESP®requires an extremely qualified and
experienced driver.
iActivate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize the
vehicle if the vehicle starts to skid or a
wheel starts to spin.
!Avoid spinning the driven wheels for an
extended period with ESP®deactivated.
You could otherwise damage the drivetrain.

Characteristics of activated SPORT
handling mode
If SPORT handling mode is activated and one
or more wheels start to spin, theESP®
warning lamp in the instrument cluster
flashes. ESP®only stabilizes the vehicle to a
limited degree.
When SPORT handling mode is activated:
RESP®only improves driving stability to a
limited degree.
Rtraction control is still activated.
Rengine torque is only restricted to a limited
degree, and the drive wheels are able to
spin.
The spinning of the wheels results in a
cutting action for better traction on loose
surfaces.
RESP®still provides support when you
brake.

XPlace the new wheel on the wheel hub and
push it on.
XTighten the wheel bolts until they are
finger-tight.
Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
XPlace the ratchet wrench onto the hexagon
nut of the jack so that the lettersABare
visible.
XTurn the ratchet wrench until the vehicle is
once again standing firmly on the ground.
XPlace the jack to one side.
XTighten the wheel bolts evenly in a
crosswise pattern in the sequence
indicated (to). The tightening torque
must be96 lb-ft (130 Nm).
XTurn the jack back to its initial position.
XStow the jack and the rest of the vehicle
tools in the vehicle again.
XCheck the tire pressure of the newly
mounted wheel and adjust it if necessary.
Observe the recommended tire pressure
(Ypage 316).
iVehicles with tire pressure monitor: all
wheels mounted must be equipped with
functioning sensors.
