important information when circumstances
require you to place a child in the
passenger seat:
R
Your vehicle is equipped with air bag
technology designed to turn off the
passenger front air bag in your vehicle
when
the Occupant Classification System
senses the weight of a typical
12‑month‑old child or less along with the
weight of an appropriate child restraint
on the passenger seat.
R A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates in a collision.
R If you install a rear-facing child
restraint on the passenger seat, make
sure the 4 0 indicator lamp
is illuminated, indicating that the
passenger front air bag is deactivated.
Should the 4 0 indicator
lamp not illuminate or go out while the
restraint is installed, please check
installation. Periodically check the
4 0 indicator lamp while
driving to make sure the
4 0 indicator lamp is
illuminated. If the 4 0
indicator lamp goes out or remains out,
do not transport a child on the passenger
seat until the system has been repaired.
A child in a rear-facing child restraint
on the passenger seat may be seriously
injured or even killed if the passenger
front air bag inflates.
R If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible, use
a proper child restraint recommended
for the age, size and weight of the child,
and secure child restraint with the
vehicle’s seat belt according to the child
seat manufacturer’s instructions. For
children larger than the typical
12‑month‑old child, the passenger front
air bag may or may not be activated. G
WARNING
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries
is significantly increased if the child
restraints are not properly secured in the
vehicle and/or the child is not properly
secured in the child restraint.
Children too big for a toddler restraint
must
ride in a seat using regular seat belt.
Position shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs
until they reach a height where a lap-
shoulder belt fits properly without a
booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in
a child restraint system. Unsupervised
children in a child restraint system may
use vehicle equipment and may cause an
accident and/or serious personal injury.
If you are using a rear-facing child
restraint system on the passenger seat, you
must verify that the passenger front air bag
is deactivated. When the passenger front
air bag is deactivated, the
4 0 indicator lamp is
illuminated (Y page 41).
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. 44

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 142)
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 Brake System (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
engine is running.
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.
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. 46

through the ESP
®
may otherwise seriously
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 217). 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 69) or until the
speed of the vehicle has exceeded 6 mph
(10 km/h). Anti-theft systems

Safety notes
G
WARNING
All seat adjustments, as well as fastening
of seat belts, must be done before the
vehicle is operated. G
WARNING
When adjusting the seat, make sure no one
becomes trapped.
Do not adjust the driver’s seat while
driving. Adjusting the seat while driving
could
cause the driver to lose control of the
vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined
position as this can be dangerous. You
could slide under the seat belt in a
collision. If you slide under the seat belt,
it could apply force at the abdomen or neck,
potentially causing serious or fatal
injuries. The seat backrest and seat belts
provide the best restraint when the wearer
is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as
possible with the driver still able to
operate the controls properly.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Observe the notes on the air bag system. G
WARNING
Children 12 years old and under must be
