110 Driving Safely
&_ WARNING
Always make sure that the doors, all win­dows, the power roof* and the read lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
-After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- The tire pressure must correspond to the
load -see the tire pressure sticker on the
fuel filler door.
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. On USA vehicles, the
tire pressure label is located on the driv­
er's side B-pillar. On Canada vehicles, the
tire pressure label is located either on
the driver's side B-pillar or inside the fuel
filler flap. The tire pressure label lists
the recommended cold tire inflation pressures for the vehicle at its maximum
capacity weight and the tires that were
on your vehicle at the time it was manu­
factured. For recommended tire pres­
sures for normal load conditions, please
see chapter ¢
page 216.

Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly
¢ page 109, Loading the luggage com ­
partment .
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4.5 kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be
about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment
could cause in a collision like this.
&_ WARNING ~
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­ ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous missiles into the pas­
senger compartment .
- Never attach a child safety seat tether
strap to a tie-down.

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:
- Always make sure to position the should­
er portion of the three-point belt over
the middle of child's shoulder.
- Never let the shoulder portion of the belt
rest against or across the neck , face,
chin, or throat of the child.
- Always make sure the lap belt portion of
the three-point belt is worn snug and
passes as low as possible across the
child's pelvis. Never let the belt pass over
the soft abdomen.
- Failure to properly route safety belts
over a child's body will cause severe inju­
ries in an accident or other emergency
situation
c;,page 113.
-The rear side of the booster seat should
be positioned as close as possible to the
backrest on the vehicle seat . Adjust or re ­
move the rear seat head restraint if it is
difficult to install the child seat with the
head restraint in place
¢page 65. Install
the head restraint again immediately
once the child seat is removed. Driving
without head restraints or with head re­
straints 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.

LATCH Lower
anchorages and tethers
for children
Child Restraint System anchors and how
are they related to child safety
T o p rov ide a simple r and more prac ticable way
to attach the c hild restraint on the vehi cle
seat, Federal regulat ions req uire spec ia l lower
anchorages in vehicles and devices on new
c hi ld restra ints to attach to the veh icle ancho­
rages.
The combination of the tether anchorages and
the lower anchorages is now genera lly ca lled
the
LATCH system for " Lower Anchorages and
T ethers for Chil dren."
Fo rward-faci ng chi ld restraints manufactured
after September 1, 1999, are requ ired by U.S.
federa l regu lations to comply with new child
head movement performance requirements. .,.. •
•

156 Child Safet y
These new performance requirements make a
tether necessary on most new child seats.
Ins tal ling a chi ld restraint that requ ires a top
tether without one can serious ly impair the
performance of the child restraint and its abi l­
ity to protect the chi ld in a co llis ion. Installing
a child restraint that requires a top tether
witho ut the top tether may be a v io lation of
state law .
Child restraint manufacturers offer LATCH l ower anchorages on the ir ch ild seats with
hook-on or push -on connectors attached to
adjustable straps.
In addit ion to the LATCH lower anchorages ,
these child restraint systems usually require
the use of tether straps to help keep the child restraint firmly in place.
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of injury and death in
a c rash .
- Always follow the instructions p rov ided
by the manufacturer of the ch ild re­
st raint you intend to install in your veh i­
cle.
- Never install a child restraint without a
properly atta ched top tether strap if the
child rest rain t manufacturer's instruc­
tions req uire the top tethe r strap to be
used.
- Improper use of c hild restra int LA TCH
lower anchorage points can lead to injury
in a collis ion . The LATCH lower anchorage
points are designed to w ithstand only
those loads imposed by correct ly fitted
child restraints.
- Never mount two chi ld restraint systems
on one LATCH Lower anchorage point.
- Never secure or attach any L uggage or
other item to the LATCH lower anchorag­
es.
@ Tips
- In Canada, the terms "top tether" with
"lower universa l anchorages" (or " lower
-
unive rsal ancho rage bars") a re used to
describe the system.
- In o ther coun tries, the term " ISOFI X" is
used to describe the Lower anc ho rages .
