brake and may also reduce engine power to
lessen the chance that wheel lift will occur.
ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving
maneuvers; it cannot prevent wheel lift due to
other factors, such as road conditions, leav-
ing the roadway, or striking objects or other
vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading,
road conditions and driving conditions,
influence the chance that wheel lift or
rollover may occur. ERM cannot prevent all
wheel lift or roll overs, especially those
that involve leaving the roadway or striking
objects or other vehicles. The capabilities
WARNING!
of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user's
safety or the safety of others.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take
the appropriate actions to attempt to stop the
sway. TSC will become active automatically
once an excessively swaying trailer is recog-
nized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced andyou may feel the brakes being applied to
individual wheels to attempt to stop the
trailer from swaying. TSC is disabled when
the ESC system is in the “Partial Off” or “Full
Off” modes.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.

Everyone in your vehicle needs to be buckled
up at all times, including babies and chil-
dren. EC directive 2003/20/EC requires
proper use of restraints in all EC countries.
Children less than 1.5 meters tall and
12 years or younger should ride properly
buckled up in a rear seat, if available. Accord-
ing to crash statistics, children are safer
when properly restrained in the rear seats
rather than in the front.
WARNING!
• NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• Only use a rear-facing child restraint in
the rear seat of a vehicle with a rear seat.
• A deploying passenger front airbag can
cause death or serious injury to a child
WARNING!
12 years or younger, including a child in
a rear-facing child restraint.
• In a collision, an unrestrained child can
become a projectile inside the vehicle.
The force required to hold even an infant
on your lap could become so great that
you could not hold the child, no matter
how strong you are. The child and others
could be badly injured or killed. Any
child riding in your vehicle should be in
a proper restraint for the child’s size.
There are different sizes and types of re-
straints for children from newborn size to the
child almost large enough for an adult safety
belt. Children should ride rearward facing as
long as possible; this is the most protected
position for a child in the event of a crash.
Always check the child seat Owner’s Manual
to make sure you have the correct seat for
your child. Carefully read and follow all theinstructions and warnings in the child re-
straint Owner’s Manual and on all the labels
attached to the child restraint.
In Europe, children restraint systems are de-
fined by regulation ECE-R44, which divides
them into five weight groups:
Restraint Group Weight Group
Group 0 up to 10 kg
Group 0+ up to 13 kg
Group 1 9-18 kg
Group 2 15-25 kg
Group 3 22-36 kg
Check the label of your child restraint. All
approved child restraints must include type-
approval data and the control mark on its
label. The label must be permanently se-
cured to the child restraint system. You
should not remove this label from the child
restraint.
119

An example of a Universal ISOFIX child re-
straint system for weight group 1 is shown in
fig. E. ISOFIX child restraints are also avail-
able in the other weight groups.
Locating The ISOFIX Anchorages
The lower anchorages are round bars that are
found at the rear of the seat cushion where it
meets the seatback, below the anchorage
symbols on the seatback. They are just visible
when you lean into the rear seat to install the
child restraint. You will easily feel them if you
run your finger along the gap between the
seatback and seat cushion.
Locating The Tether Anchorages
There are tether strap anchorages behind
each rear seating position located on the
back of the seat. To access them, pull the
carpeted floor panel away from the seat back,
this will expose the top tether strap anchor-
ages.
ISOFIX child restraint systems will be
equipped with a rigid bar on each side. Each
will have a connector to attach to the lower
anchorage and a way to tighten the connec-
tion to the anchorage. Forward-facing child
restraints and some rear-facing child re-straints may also be equipped with a tether
strap. The tether strap will have a hook at the
end to attach to the top tether anchorage and
a way to tighten the strap after it is attached
to the anchorage.
Center Seat ISOFIX
WARNING!
• Do not install a child restraint in the
center position using the ISOFIX sys-
tem. This position is not approved for
any type of ISOFIX child restraint sys-
tem.
• Do not install your ISOFIX child restraint
system using the center tether anchor-
age. Use the seat belt to install a child
seat in the center seating position.
• Never use the same lower anchorage to
attach more than one child restraint.
Please refer to “To Install An ISOFIX
Child Restraint” for typical installation
instructions.

ENGINE BREAK-IN
RECOMMENDATIONS
3.6L & 5.7L Engines
A long break-in period is not required for the
drivetrain (engine, transmission, clutch, and
rear axle) 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 contrib-
utes to a good break-in. However, wide-open
throttle acceleration in low gear can be det-
rimental and should be avoided.The engine oil, transmission fluid, and axle
lubricant installed at the factory is high-
quality and energy-conserving. Oil, fluid, and
lubricant changes should be consistent with
anticipated climate and conditions under
which vehicle operations will occur. For the
recommended viscosity and quality grades,
refer to “Fluids And Lubricants” in "Techni-
cal Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as an indication of difficulty. Please check
your oil level with the engine oil indicator
often during the break in period. Add oil as
required.
Diesel Engine
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• Warm up the engine before placing it under
load.
• Do not operate the engine at idle for pro-
longed periods.
• Use the appropriate transmission gear to
prevent engine lugging.
• Observe vehicle oil pressure and tempera-
ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds
when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer tow-
ing or no load operation will extend the time
before the engine is at full efficiency. Re-
duced fuel economy and power may be seen
at this time.
