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 and
you 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.
Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driving
while in 4WD Low Range. HDC maintains
vehicle speed while descending hills during
various driving situations. HDC controls ve-
hicle speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not
activate).
2. Enabled (feature is enabled and ready but
activation conditions are not met, or driver
is actively overriding with brake or throttle
application).
3. Active (feature is enabled and actively
controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch,
but the following conditions must also be met
to enable HDC:
• Driveline is in 4WD Low Range
• Vehicle speed is below 5 mph (8 km/h).
• Parking brake is released.

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 the
instructions 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.
WARNING!
Extreme Hazard! Do not place a rear-
facing child restraint in front of an active
air bag. Refer to visor mounted labels for
information. Deployment of the air bag in
an accident could cause fatal injuries to
the baby regardless of the severity of the
WARNING!
collision. It is advisable to always carry
children in a child restraint system on the
rear seat, which is the most protected
position in the event of a collision.
WARNING!
Should it be necessary to carry a child on
the passenger side front seat in a rear-
facing child restraint system, the passen-
ger side front airbag and side bag (for
versions/markets, where provided) must
be deactivated through the Setup menu.
Deactivation should be verified by check-
ing whether the warning light is switched
on in the instrument panel. The passenger
seat must also be positioned backward as
far as possible to avoid the child restraint
system from coming into contact with the
dashboard.
“Universal” Child Restraint Systems
• The figures in the following sections are
examples of each type of universal child
restraint system. Typical installations are

Seat Belts For Older Children
Children over 1.50 m in height can wear seat
belts instead of using child restraints.
Use this simple 5-step test to decide whether
the seat belt properly fits the child or if they
should still use a Group 2 or Group 3 child
restraint to improve the fit of the seat belt:
1. Can the child sit all the way back against
the back of the vehicle seat?
2. Do the child’s knees bend comfortably
over the front of the vehicle seat – while
the child is still sitting all the way back?
3. Does the shoulder belt cross the child’s
shoulder between the neck and arm?
4. Is the lap part of the belt as low as
possible, touching the child’s thighs and
not the stomach?
5. Can the child stay seated like this for the
whole trip?
If the answer to any of these questions was
“no,” then the child still needs to use a Group
2 or 3 child restraint in this vehicle. If the
child is using the lap/shoulder belt, check
belt fit periodically and make sure the seatbelt buckle is latched. 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, or use a booster seat to position the
seat belt on the child correctly.
WARNING!
Never allow a child to put the shoulder belt
under an arm or behind their back. In a
crash, the shoulder belt will not protect a
child properly, which may result in serious
injury or death. A child must always wear
both the lap and shoulder portions of the
seat belt correctly.
ISOFIX Restraint System
Your vehicle is equipped with the child restraint
anchorage system called ISOFIX. This system
allows ISOFIX-equipped child seats to be in-
stalled without using the vehicle’s seat belts.
The ISOFIX system has two lower anchorages
located at the back of the seat cushion where it
meets the seatback and a top tether anchorage
located behind the seating position.
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.

These child restraint systems, built and type-
approved according to the i-Size (ECE R129)
standard, ensure better safety conditions to
carry children on board a vehicle:
• The child must be transported rearward
facing until 15 months;
• Child restraint system protection is in-
creased in the event of a side collision;
• The use of the ISOFIX system is promoted
to avoid faulty installation of the child re-
straint system;
• Efficiency in the choice of the child re-
straint system, which isn't made according
to weight anymore but according to the
child's height, is increased;
• Compatibility between the vehicle seats
and the child restraint systems is better:
the i-Size child restraint systems can be
considered as "Super ISOFIX"; this means
that they can be perfectly fitted in type-
approved i-Size seats, but can also be fitted
in ISOFIX (ECE R44) type-approved seats.NOTE:
The vehicle seats, i-Size type-approved, are
marked by the symbol shown in “Figure XX”.
The following table, according to
European standard ECE 129, in-
dicates the possibility of i-Size

tion.

Transporting Pets
Air Bags 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 colli-
sion.
Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers
that are secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
WARNING!
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
• It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
