Cornering Brake Control System (CBC)
The system acts when braking on corners, optimizing
the distribution of brake pressure on the four wheels:
the system prevents the wheels on the inside of the
corner (less affected by the weight of the vehicle) from
locking, ensuring better stability and direction for the
vehicle.
Drag Torque Control System (DTC)
This is an integral part of the ESC system and inter-
venes in the event of sudden downshifting, or during
braking when the ABS intervenes, restoring torque to
the engine and thus preventing excessive drag at the
drive wheels, which may lead the wheels to lock and a
loss of vehicle stability, above all in low-grip conditions.
AntiSlip Regulation System (ASR)
WARNING!
•Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded

WARNING! (Continued)
by prevailing road conditions. ESC cannot pre-
vent all collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot pre-
vent collisions resulting from loss of vehicle
control due to inappropriate driver input for the
conditions. Only a safe, attentive, and skillful
driver can prevent collisions. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.
• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that reduces the
effectiveness of the ESC system can increase the
risk of loss of vehicle control, vehicle rollover,
personal injury and death.

SAFETY 93

Electronic Q2 System (E-Q2)
TheElectronic Q2 system intervenes during accelera-
tion on corners, braking the inner drive wheel and thus
increasing the traction of the outer wheel (which bears
more of the vehicles weight): the torque is thus distrib-
uted optimally between the drive wheels in accordance
with the driving conditions and road surface, permit-
ting particularly effective, sporty driving.
Ready Alert Brake System (RAB)
This function activates automatically if the accelerator
pedal is released rapidly, reducing the brake pad travel
(both at front and back), with the aim of preparing the
braking system and enhancing its responsiveness, thus
reducing the stopping distance in the event of subse-
quent braking.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation pressure must
not exceed the maximum inflation pressure molded into
the tire sidewall. Refer to “Tires” in “Servicing And
Maintenance” for information on how to properly in-
flate the vehicle’s tires. The tire pressure will also
increase as the vehicle is driven - this is normal and
there should be no adjustment for this increased pres-
sure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
limit for any reason, including low temperature effects,
or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold placard pressure. Once the low tire
pressure warning (Tire Pressure Monitoring [TPM] Tell-
tale Light) illuminates, you must increase the tire pres-
sure to the recommended cold placard pressure in order
for the TPM Telltale Light to turn off. The system will

There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner ’s Manual to make sure you have the correct
seat for your child. Carefully read and follow all the
instructions and warnings in the child restraint Own-
er ’s Manual and on all the labels attached to the child
restraint.
Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. You should also make sure that you can
install it in the vehicle where you will use it.NOTE:

straint
Larger Children Children who have outgrown their forward-facing child restraint, butare too small to properly fit the vehicle’s seat belt Belt Positioning Booster Seat and
the vehicle seat belt, seated in the rear seat of the vehicle
Children Too Large for Child Restraints Children 12 years old or younger,
who have outgrown the height or weight limit of their booster seat Vehicle Seat Belt, seated in the rear
seat of the vehicle
Infant And Child Restraints
Safety experts recommend that children ride rear-facing
in the vehicle until they are two years old or until they
reach either the height or weight limit of their rear-
facing child restraint. Two types of child restraints can
be used rear-facing: infant carriers and convertible child
seats.
The infant carrier is only used rear-facing in the vehicle.
It is recommended for children from birth until they
reach the weight or height limit of the infant carrier.
Convertible child seats can be used either rear-facing or
forward-facing in the vehicle. Convertible child seats
often have a higher weight limit in the rear-facing
direction than infant carriers do, so they can be used rear-facing by children who have outgrown their infant
carrier but are still less than at least two years old.
Children should remain rear-facing until they reach the
highest weight or height allowed by their convertible
child seat.
WARNING!
•
Never place a rear-facing child restraint in front of
an air bag. A deploying passenger front air bag
can cause death or serious injury to a child 12
years or younger, including a child in a rear-
facing child restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.

SAFETY 125

Older Children And Child Restraints
Children who are two years old or who have outgrown
their rear-facing convertible child seat can ride forward-
facing in the vehicle. Forward-facing child seats and
convertible child seats used in the forward-facing direc-
tion are for children who are over two years old or who
have outgrown the rear-facing weight or height limit of
their rear-facing convertible child seat. Children should
remain in a forward-facing child seat with a harness for
as long as possible, up to the highest weight or height
allowed by the child seat.
All children whose weight or height is above the
forward-facing limit for the child seat should use a
belt-positioning booster seat until the vehicle’s seat
belts fit properly. If the child cannot sit with knees bent
over the vehicle’s seat cushion while the child’s back is
against the seatback, they should use a belt-positioning
booster seat. The child and belt-positioning booster seat
are held in the vehicle by the seat belt.
WARNING!
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the child restraint manufacturer ’s
directions exactly when installing an infant or
child restraint.
• After a child restraint is installed in the vehicle,
do not move the vehicle seat forward or rearward
because it can loosen the child restraint attach-
ments. Remove the child restraint before adjust-
ing the vehicle seat position. When the vehicle
seat has been adjusted, reinstall the child re-
straint.
• When your child restraint is not in use, secure it
in the vehicle with the seat belt or LATCH anchor-
ages, or remove it from the vehicle. Do not leave
it loose in the vehicle. In a sudden stop or
accident, it could strike the occupants or seat-
backs and cause serious personal injury.

Frequently Asked Questions About Installing Child Restraints With Seat Belts
What is the weight limit (child’s weight + weight of the child re-
straint) for using the Tether Anchor with the seat belt to attach a for- ward facing child restraint? Weight limit of the Child Restraint Always use the tether anchor when
using the seat belt to install a for-ward facing child restraint, up to
the recommended weight limit of the child restraint.
Can the head restraints be re- moved? No
Can the buckle stalk be twisted to
tighten the seat belt against the belt path of the child restraint? No Do not twist the buckle stalk in a
seating position with an ALR re-tractor.
Installing A Child Restraint With A Switchable
Automatic Locking Retractor (ALR)
Child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a
lap/shoulder belt.
WARNING!
•Improper installation or failure to properly secure
a child restraint can lead to failure of the restraint.
The child could be badly injured or killed.

WARNING! (Continued)
•Follow the child restraint manufacturer ’s direc-
tions exactly when installing an infant or child
restraint.
1. Place the child seat in the center of the seating position. Move the vehicle seat as far rearward as
possible to keep the child as far from the advanced
passenger air bag as possible.

2. Pull enough of the seat belt webbing from theretractor to pass it through the belt path of the child
restraint. Do not twist the belt webbing in the belt
path.
3. Slide the latch plate into the buckle until you hear a “click.”
4. Pull on the webbing to make the lap portion tight against the child seat.
5. To lock the seat belt, pull down on the shoulder part of the belt until you have pulled all the seat belt
webbing out of the retractor. Then, allow the web-
bing to retract back into the retractor. As the webbing
retracts, you will hear a clicking sound. This means
the seat belt is now in the Automatic Locking mode.
6. Try to pull the webbing out of the retractor. If it is locked, you should not be able to pull out any
webbing. If the retractor is not locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child restraint while you push
the child restraint rearward and downward into the
vehicle seat. 8. If the child restraint has a top tether strap and the
seating position has a top tether anchorage, connect
the tether strap to the anchorage and tighten the
tether strap. See the section “Installing Child Re-
straints Using the Top Tether Anchorage” for direc-
tions to attach a tether anchor.
9. Test that the child restraint is installed tightly by pulling back and forth on the child seat at the belt
path. It should not move more than 1 inch (25.4 mm)
in any direction.
Any seat belt system will loosen with time, so check the
belt occasionally, and pull it tight if necessary.
Installing Child Restraints Using The Top Tether
Anchorage:
Always use the tether anchor when using the seat belt
to install a forward facing child restraint, up to the
recommended weight limit of the child restraint. This
vehicle is equipped with a tether anchorage, located
behind the front passenger seat, near the floor.
