Child safety
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs . and
80 lbs. (18 kg and 36 kg) who are less than 4
ft.
9 in . (57 inches/1.45 meters) tall.
Fig. 260 Rear seat: ch ild proper ly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft . 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs .
(36 kg). Booster seats raise these child ren up so
that the safety belt will pass properly
over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
• Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a chi ld on a booster seat.
• The shoulder be lt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelv is and never
across the stomach or abdomen . Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
• If you must transport an older child in a boos­
te r seat on the front passenger seat, you can
use the safety belt height adj ustment to help
adjust the shoulder portion properly .
• Secure unused safety belts on the rear seat
qpage308.
Children up to at least 8 years old (over 40 lbs . or
18 kg) are best protected in child safety seats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
312
must not use the vehicle safety belts without a
suitable child restraint.
It is usually best to put these children in appro­
pr iat e 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 be lt
over the chi ld's body is very important
for t he child's protection, whether or not a boos­
ter 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 inches/
1.45 meters) ta ll 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
c hil d is. Always remember that children do not
have the p ronounced pelvic structure required for
the proper function of lap be lt portion of the
ve­
hicle's three point lap and shoulder belts. The
c hild' s safety abso lutely requ ires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pe lvis. Never let
the lap belt portion of the safety belt pass over
the chi ld 's stomach or abdomen.
In a crash, airbags must inflate within a blink of
an eye and with considerab le force . In order to do
i ts job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­
pant
moves forward into the airbag.
A vehicle occupant who is out of position and too
close to the a irbag 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 injury.
In order for the a irbag to
offer protection, it is
important that all vehicle occupants, especially
any ch ildren, who must be in the front seat be­
cause of exceptional c ircumstances, be properly
r estra ined and as far away from the a irbag as
possible. By keeping room between the child's

body and the front of the passenger compart­
ment, the airbag can inflate comp letely and pro­
vide supp lemental protect ion in certain frontal
collisions.
& WARNING
Not using a booster seat, using the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­ properly increases the risk of serious personal
injury and dea th in a collision or other eme r­
gency sit uat ion. To help red uce the risk of se­
rious personal injury and/or death:
- T he shoulder be lt must lie as close to the
center of the child's collar bone as possible
and must lie f lat and snug on the upper
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 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 injuries in an
acc ident or other emergency situation
¢ page 268.
- The rear side of the child safety seat should
be pos itioned as close as poss ible to the
backrest on the vehicle seat. Adjust or re­
move the rear seat head restraint if it is d if­
ficult to install the child seat with the head restra int in place¢
page 74. Install the
head restraint again immediately once the
child seat is removed . Driving without head
restraints or w ith head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Never let a child put the shoulder belt under
the arm or beh ind the back, because it cou ld
cause severe injur ies in a crash.
- Children on the front seat of any car, even with Advanced Airbags, can be seriously in­
jured or even killed when an airbag 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 child leaning for­
ward, sitting sideways or out of position in
Ch ild safety
any way du ring an accident can be struck by
a dep loying airbag. Th is will result in serious
personal injury or death.

Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas ­
senger can be locked with the convertible locking
retractor to properly secure child safety seats .
The safety belts for the rear seats and for the
front passenge r's seat have a convertible locking
retractor for child safety seats. The safety belt
must be locked so that be lt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up dur ing normal driving . A ch ild
safety seat can only be properly installed when
the safety be lt is locked so that the ch ild and
c h ild safety seat will stay in place.
Always remember : Even though your veh icle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
shou ld a lways r ide in t he back seat p roperly re-
strained for their age and s ize.

LATCH system (lower
anchorages and tethers
for children)
' Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way to
attach the child restraint on the vehicle seat, Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children" . In
Canada, the terms "top tether" with "lower uni­
versal anchorages" (or "lower universal anchor­
age bars") are used to describe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
Forward-facing child restraints manufactured af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance requirements . These
new performance requirements make a tether
necessary on most new child seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per­
formance of the child restraint and its ab ility to
protect the child in a collision. Installing a child
restraint that requires a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats with hook-on or

-These anchors were developed only for child
safety seats using the
"LATCH" system .
- Never attach other ch ild safety seats, belts
or other objects to these anchors.
- Always make sure that you hear a click when
latching the seat in place. If you do not hear
a cl ick the seat is not secure and could fly
forward and hit the inter ior of the vehicle,
or be ejected from the vehicle.

General information
Applies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue/DE F) is injected into the
exhaust system in front of a nitrogen oxide cata­ l ytic converter to reduce nitrogen em issions. The
urea solution is known as Ad Blue or DEF (Diesel
Exhaust Flu id) . The informat ion that fo llows w ill
u se the name Ad B lue .
The Ad Blue is carried in a separate tank in the ve­
hicle. The Ad Blue usage accounts for approxi­
mately 1.0% to 4.0% of the diesel fuel that is

Catalytic con verter
Applies to: vehicles with gasoline engines
T he vehicle may only be driven with un leaded
gasoline, otherwise the catalytic converter will be
destroyed.
Never drive until the tank is compl ete ly empty .
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
Diesel particulate filt er
Applies to: vehicles with diesel engines
The diese l particu late filter filters near ly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under norma l driving
condit ions. If the filter cannot clean itself (for ex­
ample, because you are only driving short distan ­
ces), the filter becomes clogged with soot and
