NOTE:
The Automatic High Beams will not activate until
the vehicle is at or above 12 mph (20 km/h).
To Deactivate

1. Pull the multifunction lever toward you (or
rearward in vehicle) to manually deactivate
the system (normal operation of low
beams).

2. Push back on the multifunction lever to reactivate the system.
The Automatic High Beams can also be deacti -
vated through the Uconnect system. Refer to
“Uconnect Settings” in “Multimedia” for further
information.
Flash-To-Pass
You can signal another vehicle with your head -
lights by lightly pulling the multifunction lever
toward you. This will cause the high beam head -
lights to turn on, and remain on, until the lever
is released.
Automatic Headlights — If Equipped
This system automatically turns your headlights
on or off based on ambient light levels. To turn
the system on, turn the headlight switch clock-
wise, aligning the indicator with the AUTO on the
headlight switch. When the system is on, the
Headlight Time Delay feature is also on. This
means your headlights will stay on for up to 90
seconds after you place the ignition switch in
the OFF position. To turn the Automatic System
off, turn the headlight switch counterclockwise
to the O (off) position.
NOTE:
The engine must be running before the head -
lights will come on in the Automatic mode.
Parking Lights And Panel Lights
To turn on the parking lights and instrument
panel lights, from the O (off) position, rotate the
headlight switch clockwise to the first detent. To
turn off the parking lights, rotate the headlight
switch back to the O (off) position.
Directional LED Headlamp System — If
Equipped
This is a system consisting of LED (low/high
beam) headlights that incorporate dynamic
cornering with 5-degree inboard/15-degree
outboard swivel. The headlights continuously
and automatically adapt to the driving condi -
tions around bends or when cornering based on
steering wheel angle.
The system directs the headlights to light up the
road in the best way, taking into account the
speed of the vehicle and the bend or corner
angle, as well as the speed of steering.
The adaptive lights are automatically activated
when the vehicle is traveling above approxi -
mately 5 mph (8 km/h).
Headlights On With Wipers (Available With
Automatic Headlights Only)
When this feature is active, the headlights will
turn on approximately 10 seconds after the
wipers are turned on if the headlight switch is
placed in the AUTO position. In addition, the
headlights will turn off when the wipers are
turned off, if they were turned on by this feature.

Temperature Control
Temperature Control regulates the temperature of the air forced through the Climate Control system. The temperature
increases as you turn the temperature control knob clockwise. The temperature decreases as you turn the temperature
control knob counterclockwise.
Blower Control
Blower Control regulates the amount of air forced through the Climate Control system. There are seven blower speeds
available. The blower speed increases as you turn the blower control knob clockwise from the lowest blower setting. The
blower speed decreases as you turn the blower control knob counterclockwise.
Mode Control
Turn the Mode Control knob to adjust the airflow distribution. The airflow distribution mode can be adjusted so air comes
from the instrument panel outlets, floor outlets, defrost outlets and demist outlets. The Mode settings are as follows:
Panel Mode Panel Mode Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted to direct the flow of
air. The air vanes of the center outlets and outboard outlets can be moved up and down or side to side to regulate airflow
direction. There is a shut off wheel located below the air vanes to shut off or adjust the amount of airflow from these
outlets.
Bi-Level Mode Bi-Level Mode Air comes from the instrument panel outlets and floor outlets. A slight amount of air is directed through the defrost and
side window demister outlets.
NOTE:
Bi-Level mode is designed under comfort conditions to provide cooler air out of the panel outlets and warmer air from the
floor outlets.

STARTING AND OPERATING209
The following indicators should be used to
ensure that you have properly engaged the
transmission into the PARK position:
When shifting into PARK, pull the gear
selector toward you and move it all the way
counterclockwise until it stops.
Release the gear selector and make sure it is
fully seated in the PARK gate.
Look at the transmission gear position
display and verify that it indicates the PARK
position (P).
With brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop. NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into
PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through underdrive FIRST, SECOND,
and THIRD gears, direct FOURTH gear and over
-
drive FIFTH and SIXTH gears. The DRIVE posi -
tion provides optimum driving characteristics
under all normal operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, trav -
eling into strong head winds, or while towing a
heavy trailer), use the Electronic Range Select
(ERS) shift control (refer to “Electronic Range
Select (ERS) Operation” in this section for
further information) to select a lower gear
range. Under these conditions, using a lower
gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.
CAUTION! (Continued)
WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a
collision.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in
NEUTRAL can cause severe transmission
damage. Refer to “Recreational Towing” in
“Starting And Operating” and “Towing A
Disabled Vehicle” in “In Case Of Emergency”
for further information.

Jack Warning Label
1. If equipped, remove the spare wheel, jack,
and tools from storage.

2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them coun -
terclockwise one turn while the wheel is still
on the ground.
3. When changing the front wheel, assemble the jack driver to the jack and connect the
jack driver to the extension tube. Place the
jack under the axle as close to the tire as
possible with the jack driver extending to
the front. Connect the extension tubes and
lug wrench.

Front Jacking Locations

When changing a rear wheel, assemble the
jack driver to the jack and connect the jack
driver to the extension tubes. Securely
place the jack under the sway bar bracket (unless both tires are flat on one side, then
place jack under shock bracket) facing for
-
ward in vehicle. Connect the extension
tubes and lug wrench.

Rear Jacking Location

Before raising the wheel off the ground,
make sure that the jack will not damage
surrounding truck parts and adjust the jack
position as required.
NOTE:
If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the
surface.
Only use the jack in the positions indicated
and for lifting this vehicle during a tire
change.
If working on or near a roadway, be
extremely careful of motor traffic.
To assure that spare tires, flat or inflated,
are securely stowed, spares must be
stowed with the valve stem facing the
ground.
CAUTION!
Do not attempt to raise the vehicle by jacking
on locations other than those indicated in the
Jacking Instructions for this vehicle.
