Top tether
Top tether permits an additional
connection between a child restraint
system and the passenger seat. Proper
usage of the top tether, in accordance with
instructions provided by the child
restraint manufacturer, can further reduce
the risk of injuries.
The top tether anchorage is located on the
floor of the cargo compartment. The top
tether guide for the top tether strap is
located above, on the head restraint. X
Thread top tether strap 0028through top
tether guide 0002down the back of
passenger seat 0003to top tether
anchorage 002B.
X Attach top tether hook 002Ato top tether
anchorage 002Bon the floor of the cargo
compartment.
i If you are using divider plus*, the
hooks of the top tether and the divider
plus* are attached to the same anchorage. X
Install the child restraint system and
tighten top tether strap 0028according to
the child restraint manufacturer’s
instructions. G
WARNING
After installing top tether straps, make
sure the seat backrests are in an upright
position and are properly locked. Push and
pull on the seat backrests to ensure they are
properly secured in the locked position. If
a seat backrest is not properly locked, the
seat backrest could fold. The child seat
would no longer be properly supported or
positioned to provide its intended
benefit. That could cause serious or even
fatal injuries. Panic alarm

Introduction
G
WARNING
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in
this section cannot reduce these risks or
prevent the natural laws of physics from
acting on the vehicle.
Always adapt your driving style to the
prevailing road and weather and traffic conditions and keep a safe distance to
other road users and objects on the street.
i In winter operation, the maximum
effectiveness of the ABS, the hydraulic
brake assistant, and the ESP ®
is only
achieved with winter tires (Y page 140)
or snow chains* as required. Antilock Brake System (ABS)
G
WARNING
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead.
Pumping the brake pedal defeats the
purpose of the ABS and significantly
reduces braking effectiveness.
The Antilock BrakeSystem (ABS) regulates
the brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp in the instrument
cluster (Y page 22) comes on when you
switch on the ignition. It goes out when the
drive system is active.
Braking At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in
the brake pedal, indicating that the ABS is
regulating the brake pressure.
X
Keep firm and steady pressure on the
brake pedal while experiencing the
pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
A pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving. 44
Driving safety systems>> Safety.
* optional

Emergency brake maneuver
X
Keep continuous full pressure on the
brake pedal. G
WARNING
When the ABS is malfunctioning, the
hydraulic brake assistant and the ESP ®
are
also switched off.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the
braking distance. G
WARNING
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase brakin gor steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent
accidents, including those resulting from
excessive speed in turns, following
another vehicle too closely, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others. Electronic Stability Program (ESP
®
)
Your vehicle is equipped with the
Electronic StabilityProgram (ESP ®
). The
ESP ®
is operational as soon as the drive
system is switched on and it monitors the
vehicle’s traction (force of adhesive
friction between the tires and the road
surface) and handling.
The ESP ®
recognizes when awheel is
spinning or if the vehicle starts to skid.
By applying brakes to the appropriate
wheel and by limiting the power 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 ESP ®
warning lamp 0004in the
instrument cluster flashes when the ESP ®
is
engaged.
The ESP ®
warning lamp 0004in the
instrument cluster comes on when you
switch on the ignition. It goes out when the
drive system is active.
Depending on the driving situation, the
ESP ®
R reduces the speed
R selectively brakes individual wheels
R equalizes the speed of the driven wheels
R stabilizes the vehicle when braking
R assists you in evasive maneuvers on all
roads G
WARNING
If the ESP ®
warning lamp 0004in the
instrument cluster flashes, proceed as
follows:
R While driving off, apply as little
throttle as possible.
R While driving, ease up on the accelerator
pedal.
R 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
resulting from excessive speed. G
WARNING
The ESP ®
cannot prevent the natura llaws 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,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESP ®
equipped vehicle must never be exploited
in a reckless or dangerous manner which Driving safety systems

could jeopardize the user’s safety or the
safety of others.
! Because the ESP ®
operates
automatically, the ignition must be
switched off when the parking brake is
being tested on a brake test
dynamometer. Active braking action
through the ESP ®
may otherwis eseriously
damage the brake system which is not
covered by the smart Limited Warranty.
i The ESP ®
will only function properly if
you use wheels of the recommended tire
size (Y page 210). Hydraulic brake assistant
The hydraulic brake assistant operates in
emergency situations. If you apply the
brakes very quickly, the hydraulic brake
assistant automatically provides full
brake boost, thereby potentially reducing
the braking distance.
X Apply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The
hydraulic brake assistant is then
deactivated. G
WARNING
When the hydraulic brake assistant is
malfunctioning, the brake system is still
functioning normally, but without the
additional brake boost that would normally
be provided during an emergency braking
maneuver. Therefore, the braking distance
may increase. G
WARNING
The hydraulic brake assistant cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase braking efficiency beyond that afforded by
the condition of the vehicle brakes and
tires or the traction afforded. The
hydraulic brake assistant cannot prevent
accidents, including those resulting from
excessive speed in turns, following
another vehicle too closely, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a hydraulic brake assistant
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others. Activating the hazard warning flasher
after an emergency braking maneuver
If you bring the vehicle to a complete stop
by strongly braking at a speed of more than
43 mph (70 km/h), the hazard warning
flasher comes on automatically as soon as
the vehicle is at a standstill. The hazard
warning flasher will remain on until it is
switched off using the hazard warning
flasher switch (Y page 66) or until the
speed of the vehicle has exceeded 6mph
(10 km/h). Anti-theft systems
Electronic immobilizer
The electronic immobilizer prevents
unauthorized persons from starting your
vehicle.
When leaving the vehicle, always take the
key with you and lock the vehicle. The drive
