I nfants up to about one year (20 lbs. or 9 kg)
are best protected in special infant carriers
and chi ld safety seats designed for their age
group. Many experts believe that infants and
small children should ride only in special re­
straints in which the child faces the back of
the vehicle . These infant seats support the ba­

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.
F ig . 122 Passen ger seat : child p roper ly rest ra in ed in a
booster sea t
The vehicle's safety belts alone will not fit
most children until they are at least 4
ft . 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs .
(36 kg). Booster sea ts ra ise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
.,. Do no t use the convertible locking retr actor
when using the vehicle's safety belt to re­ strain a child on a booster seat .
.. The shoulder be lt must lie as close to the
center of the child 's collar bone as possible
and must lie 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 . P ull on the be lt
to t ighten if necessary.
Ch ildren up to at least 8 years old (over 40
lbs . or 18 kg) are best protected in child safe­
ty seats designed for the ir age and we ight. Ex­
perts say that the ske letal structu re, pa rticu­
l arly the pelvis, of these ch ildren is not fully
developed, and they m ust not use the vehicle
safety belts without a suitab le child restraint.
It is us ually best to put these childre n in ap­
propriate booster seats. Be sure the booster
seat meets all app licab le safety standards. Child S
afety 13 7
Booster seats ra ise the seating pos ition o f the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the ch ild's body in the right p laces. The
routing of the belt over the ch ild's body is very
important for the child's protect ion, whether
o r not a booster seat is used.
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 port io n of the vehicle's
safety be lt alone to restra in any chi ld, regard­
less of how big the ch ild is. Always remember
that children do not have the prono unced pel­
vic struc ture required for the proper funct ion
of lap belt portion of the vehicle's three point
lap and shou lder belts. The child 's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as poss ible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
c hi ld 's stomach or abdomen.
In a crash , a irbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the a irbag needs room to i nflate
so that it will be the re to protect the occupant
as the occupant moves forward into the a ir­
bag .
A vehicle occupant who is out of posit ion 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 st ruck violently and
will receive se rious or possibly even fat al in-
J LI ry .
In order for the airbag to offer protection, it is
importan t that all veh icle occupants, espec ial­
ly any children, who m ust be in t he front sea t
because of exceptional c ircumstances, 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 a irbag can inflate com­
pletely and provide supplemental protection
in ce rtain frontal collisions .

Not using a booster seat, using the boos­
ter seat improperly, incorrectly install ing 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 eme rgency s ituation. To help re­
duce the risk of serious persona l injury
and/or death:
- T he shoulder belt must lie as close to the

a convertible locking retracto r for child re­
straints. The safety be lt must be locked so
that belt webbing cannot unreel. The retrac­
tor can be activated to lock the safety belt and
prevent the safety be lt webbing from loosen ­
ing up during normal driving. A child safety
seat can only be properly installed when the
safety belt is locked so that the child and child safety seat wi ll stay in place .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, a
child should always ride in the seat properly
restrained for its age and s ize.

Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffic §&and weather conditions. ESC
cannot override the vehicle's physical limits,
increase the available traction, or keep a vehi­
cle on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle go ing in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works togethe r with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..
