could cause personal injury if the Active
Head Restraint is deployed.
Adjustment — Rear Seats
The head restraints on the outboard seats are
not adjustable. They automatically fold for-
ward when the rear seat is folded to a load
floor position, but do not return to their nor-
mal position when the rear seat is raised.
After returning either seat to its upright posi-
tion, raise the head restraint until it locks in
place. The outboard head restraints are not
removable.
The center head restraint has limited adjust-
ment. Lift upward on the head restraint to
raise it, or push downward on the head re-
straint to lower it.
Head Restraint Removal — Rear Seats
The center head restraint can be adjusted
when occupied, or removed for Child Seat
Tethering. To remove the head restraint, raise
it as far as it can go by pulling upward. Then,
push the release button at the base of the
post while pulling the head restraint upward.
To reinstall the head restraint, put the head
restraint posts into the holes and push down-
ward. Then, adjust the head restraint to the
appropriate height.
WARNING!
• ALL the head restraints MUST be rein-
stalled in the vehicle to properly pro-
tect the occupants. Follow the re-
installation instructions above prior to
operating the vehicle or occupying a
seat.
• Sitting in a seat with the head restraint
in its lowered position could result in
serious injury or death in a collision.
Always make sure the outboard head
restraints are in their upright positions
when the seat is to be occupied.Folded Rear Head Restraint

defective outside light bulb. If an indicator
fails to light when the lever is moved, it would
suggest that the indicator bulb is defective.
Automatic Headlight Leveling — HID
Headlights Only
This feature prevents the headlights from
interfering with the vision of oncoming driv-
ers. Headlight leveling automatically adjusts
the height of the headlight beam in reaction
to changes in vehicle pitch.
Battery Saver

hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause

NOTE:
The adjustable upper shoulder belt anchor-
age is equipped with an Easy Up feature. This
feature allows the shoulder belt anchorage to
be adjusted in the upward position without
pushing or squeezing the release button. To
verify the shoulder belt anchorage is latched,
pull downward on the shoulder belt anchor-
age until it is locked into position.
WARNING!
• Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
your seat belt safely and to keep your
passengers safe, too.
• Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
• Misadjustment of the seat belt could
reduce the effectiveness of the safety
belt in a crash.
WARNING!
• Always make all seat belt height adjust-
ments when the vehicle is stationary.
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants
including pregnant women: the risk of injury
in the event of an accident is reduced for the
mother and the unborn child if they are wear-
ing a seat belt.Position the lap belt snug and low below the
abdomen and across the strong bones of the
hips. Place the shoulder belt across the chest
and away from the neck. Never place the
shoulder belt behind the back or under the
arm.
Seat Belt Pretensioner
The front outboard seat belt system is
equipped with pretensioning devices that are
designed to remove slack from the seat belt in
the event of a collision. These devices may
improve the performance of the seat belt by
removing slack from the seat belt early in a
collision. Pretensioners work for all size oc-
cupants, including those in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi-
tioned properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air bag
must be replaced immediately.

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 seat
belt 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 re-
straint anchorage system called ISOFIX. This
system allows ISOFIX-equipped child seats
to be installed 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 seat-
ing position.

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differen-
tial (ELSD) rear axle and the Quadra-Trac II
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to
operate. Under normal driving conditions,
the unit functions as a standard axle, balanc-
ing torque evenly between left and rightwheels. With a traction difference between
left and right wheels, the coupling will sense
a speed difference. As one wheel begins to
spin faster than the other, torque will auto-
matically transfer from the wheel that has
less traction, to the wheel that has traction.
While the transfer case and axle coupling
differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shift-
ing information, preceding this section, for
shifting this system.
QUADRA-LIFT — IF
EQUIPPED
Description
The Quadra-Lift air suspension system pro-
vides full time load leveling capability along
with the benefit of vehicle height adjustment
by the push of a button. The vehicle will
automatically raise and lower the ride height
to adapt to the appropriate driving condi-
tions. At higher speeds, the vehicle will lower
to an aerodynamic ride height and when op-
erating in off-road modes, the vehicle will
raise the ride height accordingly. The buttonsnear the terrain switch in the center console
area can be used to set preferred ride height
to match the appropriate conditions.
•Normal Ride Height (NRH)– This is the stan-
dard position of the suspension and is
meant for normal driving.

•Off-Road 1 (OR1) (Raises the vehicle approxi-
mately 1.1 inches (28 mm))– This is the
primary position for all off-road driving until
OR2 is needed. A smoother and more com-
fortable ride will result. Push the “UP”
button once from the NRH position while
the vehicle speed is below 38 mph
(61 km/h). When in the OR1 position, if the
vehicle speed remains between 40 mph
(64 km/h) and 50 mph (80 km/h) for
greater than 20 seconds or if the vehicle
speed exceeds 50 mph (80 km/h), the
vehicle will be automatically lowered to
NRH.
•Off-Road 2 (OR2) (Raises the vehicle approxi-
mately 2.2 inches (55 mm))– This position is
intended for off-roading use only where
maximum ground clearance is required. To
enter OR2, push the “UP” button twice
from the NRH position or once from the
OR1 position while vehicle speed is below
20 mph (32 km/h). While in OR2, if the
vehicle speed exceeds 25 mph (40 km/h)
the vehicle height will be automatically
lowered to OR1.•Aero Mode (Lowers the vehicle approximately
0.6 inches (15 mm))– This position provides
improved aerodynamics by lowering the ve-
hicle. The vehicle will automatically enter
Aero Mode when the vehicle speed remains
between 52 mph (83 km/h) and 56 mph
(90 km/h) for greater than 20 seconds or if
the vehicle speed exceeds 56 mph
(90 km/h). The vehicle will return to NRH
from Aero Mode if the vehicle speed re-
mains between 20 mph (32 km/h) and
25 mph (40 km/h) for greater than 20 sec-
onds or if the vehicle speed falls below
20 mph (32 km/h). The vehicle will enter
Aero Mode, regardless of vehicle speed if
the vehicle is in “SPORT” mode.
•Entry/Exit Mode (Lowers the vehicle approxi-
mately 1.6 inches (40 mm)– This position
lowers the vehicle for easier passenger en-
try and exit as well as lowering the rear of
the vehicle for easier loading and unloading
of cargo. To enter Entry/Exit Mode, push the
“DOWN” button once from (NRH) while the
vehicle speed is below 25 mph (40 km/h).
Once the vehicle speed goes below 15 mph
(24 km/h) the vehicle height will begin to
lower. If the vehicle speed remains between15 mph (24 km/h) and 25 mph (40 km/h)
for greater than 60 seconds, or the vehicle
speed exceeds 25 mph (40 km/h) the
Entry/Exit Mode change will be cancelled.
To exit Entry/Exit Mode, press the “Up”
button once while in Entry/Exit Mode or
drive the vehicle over 15 mph (24 km/h).
NOTE:
Automatic lowering of the vehicle into Entry/
Exit Mode can be enabled through the
Uconnect Touch-Screen Radio. If this feature
is enabled, the vehicle will only lower if the
gear selector is in "PARK", the terrain switch
is in "AUTO", the transfer-case is in "AUTO”
and the vehicle level should be either in
Normal or Aero Mode. The Vehicle will not
automatically lower if the air suspension level
is in Off Rd 2 or Off Rd 1. If the vehicle is
equipped with Intrusion Theft Module (ITM),
the lowering will be suppressed when the
ignition is switched OFF and the door is open
to prevent setting the alarm off.
The Selec-Terrain switch will automatically
change the vehicle to the proper height based
on the position of the Selec-Terrain switch.
The height can be changed from the default
STARTING AND OPERATING
164

Selec-Terrain setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain”
in “Starting And Operating” for further infor-
mation.
The system requires that the engine be run-
ning for all changes. When lowering the ve-
hicle all of the doors, including the liftgate,
must be closed. If a door is opened at any
time while the vehicle is lowering the change
will not be completed until the open door(s)
is/are closed.
The Quadra-Lift air suspension system uses a
lifting and lowering pattern which keeps the
headlights from incorrectly shining into on-
coming traffic. When raising the vehicle, the
rear of the vehicle will move up first and then
the front. When lowering the vehicle, the
front will move down first and then the rear.
After the engine is turned off, it may be
noticed that the air suspension system oper-
ates briefly, this is normal. The system is
correcting the position of the vehicle to en-
sure a proper appearance.To assist with changing a spare tire, the
Quadra-Lift air suspension system has a fea-
ture which allows the automatic leveling to be
disabled. Refer to “Uconnect Settings” in
“Multimedia” for further information.
