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 practicab le 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
versa l anchorages" (or "lower universal anchor­
age bars") are used to descr ibe 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 req uirements. These
new performance requirements make a tether
necessary on most new ch ild seats.
Installing a child restraint that requires a top
tethe r 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
restra int that requi res 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 w ith hook-on or ..,.

points are only intended for installation and at­
tachment of child restraints specifically cert ified
for use with
LATCH lower anchorages. Child re­
straints that are not equipped with the lower an­
chorage attachments can still be installed in
compliance w ith the child restra int manufactur­
er 's instructions on using vehicle safety belts .
.8, WARNING
Improper use of LATCH lower anchorages can
cause serious personal injury in an accident.
- Always caref ully follow the child restra ints
man ufactu rer's inst ructions for proper in­
sta llation of the child restr aint and proper
u se of the lower anchorages or safety be lts
in your vehicle.
- Never secure or attach any luggage or other
items to the
LATCH lower anchorages.
- Always read and heed t he important infor­
mation about child restraints in this chapter
and WARNINGS

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, exp lo­
sions or serious in juries.
- Fuel ignites easily and can cause serious burns and other injuries .
- If you do not switch the eng ine off when fu­
eling and/or do not insert the fuel no zzle
completely into the tank opening, fue l can
leak out or run over . Leaked fuel can ignite
and start a fire .
- Do no t use the telephone while fueling. The
electromagnet ic rays can cause sparks,
wh ich can ignite fuel vapors and start a fire .
- Do not s it in your vehicle while fueling . If
you must make an except ion and enter your
vehicle again wh ile fue ling , close the door
and touch meta l to discha rge static electric­
ity befo re touching the fue l nozzle . Static
electricity can create spar ks, wh ich can ig­
ni te vapors when fue ling.
- Do not smoke or have an open flame i n the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of a n explosion .
- For your safety , carrying fuel containers in
your vehicle is not recommended . Whether
full or empty, the container can leak and cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
- Never fill the fuel containe r with fuel
while it is in or on the vehicle. Stat ic elec­
tr icity is d ischa rged when filling wh ich can
cause the f uel vapors to ignite and in­
creases the risk of an explos ion .
- Always p lace a fuel containe r on the
g round before fi lling .
- Always ho ld the fuel no zzle comp letely in
the fuel container when filling.
Ch eck ing and Filling
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This prevents stat ic electricity from discharg­
ing .
- Never spill fue l in the vehicle or the lug­
gage compartment. Evaporated fuel is ex ­
plosive and increases the risk of serious in­
ju ry or death .
- Follow legal req uirements when using,
stor ing and transporti ng fuel containers.
- Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
CD Note
- Remove spilled fuel from vehicle pa int im­
mediately , because it can damage paint.
- Never drive unt il the fuel tank is complete ly
empty. The irregular supply of fue l that re­
sults from that can cause eng ine misfires .
Uncombusted fuel will enter t he exhaust
system and increase the risk of damage to
the catalyti c converter .
CD Note
Applies to: vehicles with diesel engines
If the f uel tank ru ns completely empty, the
i gni tion must remain sw itched on for a t least
30 seco nds after refueling before sta rting the
engine . It may take longer than usua l for the
engine to start, even up to a minute. This is
because the air must first bleed out of the
fuel system when start ing the engine .
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the veh icle is warming up.

In vehicles with selective catalyt ic reduction, a
u rea solution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
conve rter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or D EF (Diesel Ex­
haust Fluid) . Ad Blue is used in the follow ing .
The Ad Blue is carried in a separate tank in the ve­ hicle. The AdBlue usage acco unts for approxi ­
mately 0 .5% to 2 .5% of the diese l fuel that is
u sed .

mend occasionally check ing the coo lant level
manually.
If you m ust add coolant, use a m ixture o f water
and coolant additive . M ixing the coolant additive
w ith d istilled water is recommended.
Coolant additive
The coolan t addi tive is made of ant i-freez ing and
corrosion protection agents. Only use the fo llow­
i n g coo lant additives . These additives may be
mixed wit h each other .

The amount of coo lant add itive that needs to be
mixed with water depends on the climate where
the veh icle will be ope rated. If the coolant addi­
tive percentage is too low, the cool ant can freeze
and damage the engine.
