Children up to at least 8 years old (over 40 lbs
or 18 kg) are best protected in child safety
seats designed for their age and weight. Ex­perts say that the skeletal structure, particu­
larly the pelvis, of these children is not fully
developed, and they must not use the vehicle
safety belts without a suitable child restraint.
It is usually best to put these children in ap­ propriate booster seats. Be sure the booster
seat meets all applicable safety standards .
Booster seats raise the seating position of the
child and reposition both the lap and shoulder parts of the safety belt so that they pass
across the child 's body in the right places. The
routing of the belt over the child's body is very
important for the child's protection, whether
or not a booster seat is used . Children age 12
and under must always ride in the rear seat.
Children who are at least 4
ft . 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle's three point lap and shoulder belts.
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regard­
less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function of lap belt portion of the vehicle's three point
lap and shoulder belts. The child's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as possible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
child's stomach or abdomen.
In a crash, airbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the airbag needs room to inflate
so that it will be there to protect the occupant
as the occupant moves forward into the air­
bag.
A vehicle occupant who is out of position and
too close to the airbag gets in the way of an
inflating airbag. When an occupant is too
close, he or she will be struck violently and
will receive serious or possibly even fatal in­
jury.
Child Safety 183
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial­
ly any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
airbag as possible. By keeping room between
the child's body and the front of the passen­
ger compartment, the airbag can inflate com­
pletely and provide supplemental protection
in certain frontal collisions.
A WARNING
Not using a booster seat, using the boos­
ter seat improperly, incorrectly installing a booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or other emergency situation. To help re­
duce the risk of serious personal injury
and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possi­
ble and must lie flat and snug on the up­
per body.
It must never lie across the
throat or neck. The lap belt must lie
across the pelvis and never across the
stomach or abdomen. Make sure that the
belt lies flat and snug. Pull on the belt to
tighten if necessary.
- Failure to properly route safety belts
over a child's body will cause severe inju­
ries in an accident or other emergency
situation¢
page 143.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat. Ad­
just the rear seat head restraint if it is difficult to install the child seat with the
head restraint in place
¢page 137. Driv­
ing with head restraints that are not
properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Children on the front seat of any car,
even with Advanced Airbags, can be seri­
ously injured or even killed when an air­
bag inflates.
- Never let a child stand or kneel on any
seat, for example the front seat. •

- Never let a child ride in the cargo area of
your vehicle .
- Always remember that a chi ld leaning
forward, sitt ing s ideways or out of posi­

struck by a deploying airbag . This will re­
sult in serious personal injury or death .
- If you must install a booster seat on the

Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger can be locked with the convertible
locking re tractor to properly secure child
safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the
fro nt passenger's seat safety belt have a con­
vertible locking retracto r for child restra ints .
The safety belt must be locke d so that belt
webbing can not unreel. The ret ractor ca n be
activ ated to lock the safety be lt and p revent
the safety belt webbing from loosening up
d ur ing normal driv ing . A child sa fe ty seat can
on ly be proper ly installed whe n the safety belt is loc
ked so that the chi ld and child sa fety
seat wi ll stay in place.
Alw ays remember: Even tho ugh yo ur vehicle is
equipped wi th an A dvan ced Airbag system, all

A WARNING
Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward -facing child re­
straint up, against or
very near the in­
strument panel.
- Always
move the passenger seat into its
rearmost position in the seat 's fore and

Rearward-facing child restraints:
-A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates -
even
with an Advanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof .
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances .
- A tight tether strap on a rearward-facing

vehicles with adaptive cruise control*, the brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
smal l.
Anti-slip regulati on (ASR )
ASR reduces engine power when the d rive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other d rive
wheel or whee ls if the vehicle is equipped with
all whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases, ED L automatica lly switches
off to help keep the brake on the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to normal.
Dynamic steer ing*
On vehicles with dynamic steering, ESC he lps
stabilize the steering in certain situations .
Selective wheel torque control
The se lective wheel torque cont ro l operates
when dr iving thro ugh cu rves. The front wheel
on the ins ide of the curve or both w heels on
the inside of the curve are braked selective ly
as needed. This minimizes sliding in the front
wheels and a llows for more precise driving
through curves. The applicab le system may
not activate when driving in wet or snowy con­
d itions .
Post- coll isio n br ake assis t
"Post-collision brake assist" can assist the
driver during a collision by reducing the dan­
ger of slipp ing and further collision and by au­
tomatic braking.
"Post-collision brake assist" functions d uring
collisions when the a irbag contro l modu le de­
tects a trigger level and the collision takes place at a certa in driving speed. The brak ing
of the vehicle happens automatically via the ESC as
long as the ESC, the brake system, and
the vehicle electrical system are not damaged
from the collision.
T he following ac tivit ies override the au toma t­
ic braking during a co llision:
- I f the driver p resses the acce le rator pedal.
There is no automa tic brak ing .
- When the force on the press brake peda l is
st ronger tha n the braking force initiated by
t he system. The veh icle is manua lly braked.
- When the ESC is damaged, the "Post-colli­
sion brake assist" is not available.
,&. WARNING
- ESC, ABS, ASR, ED L, dynamic steeri ng *
and the select ive wheel torque control
cannot overcome the laws of physics .
This is especially important on s lippery
or wet roads. If the systems beg in acting
to stabilize your veh icle, you should im­
mediately change your speed to match
the road and traffic conditions. Do not let the increased safety provided by
these systems tempt you to take r is ks.
D oing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per ­
sonal injuries.
- Always ad apt your speed to road, traffi c
and weather conditions . The risk of los ­

driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
