2007 JEEP GRAND CHEROKEE ECU

•If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.
•When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seat backs
and cause serious personal injury.
NOTE:For additional information refer to
www.seatcheck.org or call 1-866-SEATCHECK.
Older Children and Child Restraints
Children who weigh more than 20 lbs (9 kg) and who are
older than one year can ride forward-facing in the
vehicle. Forward-facing child seats and convertible child
seats used in the forward-facing direction, are for chil-
dren who weigh 20 to 40 lbs (9 to 18 kg), and who are
older than one year. These child seats are also held in the
vehicle by the lap/shoulder belt or the LATCH child
restraint anchorage system (Refer to LATCH — Child
Seat Anchorage System in this section.)
The belt-positioning booster seat is for children weighing
more than 40 lbs (18 kg), but who are still too small to fit
the vehicle’s seat belts properly. If the child cannot sit
with knees bent over the vehicle’s seat cushion while the
child’s back is against the seat back, they should use a
belt-positioning booster seat. The child and belt-
positioning booster seat are held in the vehicle by the
lap/shoulder belt.

Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back, should use the lap/shoulder belt in a rear seat.
•Make sure that the child is upright in the seat.
•The lap portion should be low on the hips and as snug
as possible.
•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
•If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
LATCH — Child Seat Anchorage System (Lower
Anchors and Tether for CH ildren)
Your vehicle’s rear seat is equipped with the child
restraint anchorage system called LATCH. The LATCH
system provides for the installation of the child restraint
without using the vehicle’s seat belts, instead securing
the child restraint using lower anchorages and upper
tether straps from the child restraint to the vehicle
structure.
LATCH-compatible child restraint systems are now avail-
able. However, because the lower anchorages are to be
introduced over a period of years, child restraint systems
having attachments for those anchorages will continue to
also have features for installation using the vehicle’s seat
belts. Child restraints having tether straps and hooks for
connection to the top tether anchorages have been avail-
able for some time. For some older child restraints, many
child restraint manufacturers offer add-on tether strap
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If the belt still can’t be tightened, or if by pulling and
pushing on the restraint loosens the belt, you may need
to do something more. Disconnect the latch plate from
the buckle, turn the buckle around, and insert the latch
plate into the buckle again. If you still can’t make the
child restraint secure, try a different seating position.
To attach a child restraint tether strap:
Route the tether strap over the seat back and attach the
hook to the tether anchor located on the back of the seat.
For the outboard seating positions, route the tether over
the head rests, and attach the hook to the tether anchor
located on the back of the seat.
WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the child.
Use only the anchor positions directly behind the child
seat to secure a child restraint top tether strap.

Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.

tons, begin withProgrammingstep two. Do not repeat
step one.
NOTE:If your hand-held transmitter appears to pro-
gram the universal transceiver, but your garage door
does not operate using the transmitter and your garage
door opener was manufactured after 1995, your garage
door opener may have a multiple security code system
(rolling code system). Please proceed to steps 6–8 to
complete the programming of a rolling code equipped
device (most common garage door openers require this
step.
6. At the garage door opener receiver (motor-head unit)
in the garage, locate thelearnorsmartbutton. This

Canadian Programming/Gate Programming
Canadian radio-frequency laws require transmitter sig-
nals totime-out(or quit) after several seconds of
transmission which may not be long enough for
HomeLink to pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed totime-outin the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using theProgram-
mingprocedures (regardless of where you live),replace
Programming HomeLinkstep 3with the following:
NOTE:If programming a garage door opener or gate
operator, it is advised to unplug the device during the
cyclingprocess to prevent possible overheating.
3. Continue to press and hold the HomeLink button
while youpress and release every two seconds(cycle)
your hand-held transmitter until the frequency signal has
successfully been accepted by HomeLink. The EVICdisplay will show “CHANNEL X TRAINED” (where X is
Channel 1, 2, or 3). Proceed withProgrammingstep
four to complete.
Using HomeLink
To operate, simply press and release the programmed
HomeLink button. Activation will now occur for the
trained device (i.e. garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc.). For convenience, the hand-held transmitter of the
device may also be used at any time. In the event that
there are still programming difficulties or questions,
contact HomeLink at:www.homelink.com or 1-800-355-
3515.
