90GETTING TO KNOW YOUR VEHICLE
NOTE:
Opening or closing the Hands-Free Liftgate
requires a valid Passive Entry key fob within 5 ft
(1.5 m) of the liftgate handle. If a valid Passive
Entry key fob is not within 5 ft (1.5 m), the lift -
gate will not respond to any kicks.
The Hands-Free Liftgate feature may be turned
on or off through the Uconnect system
Ú page 204.
The Hands-Free Liftgate feature should be
turned off during jacking, tire changing, manual
car wash, and vehicle service.
The Hands-Free Liftgate feature can be acti -
vated by any metallic object making a similar
in-and-out motion under the rear fascia/
bumper, such as cleaning using a metal broom.
The Hands-Free Liftgate will only operate when
the transmission is in PARK.
If anything obstructs the Hands-Free Liftgate
while it is opening or closing, the liftgate will
automatically reverse to the closed/open posi -
tion, provided it meets sufficient resistance.
There are pinch sensors attached to the side of
the liftgate opening. Light pressure anywhere
along these strips will cause the liftgate to
return to the open position.
If the power liftgate encounters multiple
obstructions within the same cycle, the system
will automatically stop. If this occurs, the liftgate
must be operated manually.
The power liftgate will release, but not power
open, in temperatures below −12°F (−24°C).
Be sure to remove any buildup of snow or ice
from the liftgate before opening the liftgate.
If the liftgate is left open for an extended period
of time (approximately one hour), the liftgate
may need to be closed manually to reset power
liftgate functionality. Gas props support the liftgate in the open position.
However, because the gas pressure drops with
temperature, it may be necessary to assist the
props when opening the liftgate in cold weather.
NOTE:Allow the power system to open the liftgate.
Manually pushing or pulling the liftgate may
activate the liftgate obstacle detection feature and
stop the power operation or reverse its direction.
CARGO AREA FEATURES
Cargo Storage
The load floor is designed for a maximum load of
300 lb (136 kg).

located on the left side of the rear cargo area.
WARNING!
Driving with the liftgate open can allow
poisonous exhaust gases into your vehicle.
You and your passengers could be injured by
these fumes. Keep the liftgate closed when
you are operating the vehicle.
If you are required to drive with the liftgate
open, make sure that all windows are closed,
and the climate control blower switch is set at
high speed. Do not use the recirculation
mode.
WARNING!
During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel
path is clear. Make sure the liftgate is closed
and latched before driving away.

23_WL_OM_EN_USC_t.book Page 90

STARTING AND OPERATING123
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)

Your vehicle is equipped with an EPB that offers
simple operation, and some additional features that
make the parking brake more convenient and useful.

The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure the parking brake is
applied. Also, be certain to leave the transmission
in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the Customer Programmable
Features section of the Uconnect settings. The parking brake switch is located on the
instrument panel to the left of the steering wheel
(below the headlamp switch).

Electric Park Brake Switch

To apply the parking brake manually, pull up on the
switch momentarily. You may hear a sound from
the back of the vehicle while the parking brake
engages. Once the parking brake is fully engaged,
the BRAKE telltale light in the instrument cluster
and an indicator on the switch will illuminate. If
your foot is on the brake pedal while you apply the
parking brake, you may notice a small amount of
brake pedal movement. The parking brake can be
applied even when the ignition switch is OFF but
the BRAKE telltale light will not illuminate,
however, it can only be released when the ignition
is in the ON/RUN position.
NOTE:The EPB Warning Light will illuminate if the EPB
switch is held for longer than 20 seconds in either
the released or applied position. The light will extin -
guish upon releasing the switch.
If the Auto Park Brake feature is enabled, the
parking brake will automatically engage whenever
the transmission is placed into PARK. If your foot is
on the brake pedal, you may notice a small amount
of brake pedal movement while the parking brake
is engaging.
The parking brake will release automatically when
the ignition is ON, the transmission is in DRIVE or
REVERSE, the driver seat belt is buckled, and an
attempt is made to drive away.
To release the parking brake manually, the ignition
switch must be in the ON/RUN position. Put your
foot on the brake pedal, then push the EPB switch
down momentarily. You may hear a sound from the
back of the vehicle while the parking brake
disengages. You may also notice a small amount of
movement in the brake pedal. Once the parking
brake is fully disengaged, the BRAKE telltale light
in the instrument cluster and the LED indicator on
the switch will extinguish.CAUTION!
Never use non-detergent oil or straight mineral
oil in the engine or damage may result.

STARTING AND OPERATING125
AUTO PARK BRAKE
The EPB can be programmed to be applied
automatically whenever the vehicle is at a
standstill and the transmission is placed in PARK.
Auto Park Brake is enabled and disabled by
customer selection through the customer
programmable features section of the Uconnect
Settings Úpage 218.
Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the release
position while the transmission is placed in PARK.
SAFEHOLD
SafeHold is a safety feature of the EPB system that
will place the transmission in PARK, and engage
the parking brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
The parking brake will automatically engage if all of
the following conditions are met:
The vehicle is at a standstill.
There is no attempt to press the brake pedal or
accelerator pedal.
The seat belt is unbuckled.
The driver door is open. SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open. Once
manually bypassed, SafeHold will be enabled
again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and
back to ON again.
HOLD ‘N GO — IF EQUIPPED
Hold ‘N Go is a comfort feature that allows the
driver to remove their foot from the brake pedal
once the vehicle has come to a stop. The vehicle
must be held at a standstill for a predetermined
amount of time by hydraulic braking. The EPB will
then engage and continue to hold the vehicle at a
stop until the driver applies the accelerator pedal.
Hold ‘N Go can be activated or deactivated by
pushing the HOLD button located on the switch
bank.

HOLD Switch
The following conditions must be met for Hold ‘N
Go to activate:
Driver’s door is closed
Driver's seat belt is fastened
Vehicle is at a standstill
Forward gear is selected
ACC is not engaged
EPB is not applied
ParkSense Active Park Assist System auto
parking maneuver is not activated
BRAKE MAINTENANCE MODE
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake
Maintenance Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the EPB
system, this can only be done after retracting the
EPB actuator. Fortunately, actuator retraction can
be done easily by entering the Brake Maintenance
Mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you
through the steps necessary to retract the EPB
actuator in order to perform rear brake service.

128STARTING AND OPERATING
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
The transmission gear selector has only PARK,
REVERSE, NEUTRAL, and DRIVE positions. Manual
downshifts can be made using the steering wheel
mounted paddle shifters. Pulling the -/+ switches
(on the steering wheel) while in the DRIVE position
will select the highest available transmission gear,
and will display that gear limit in the instrument
cluster as 1, 2, 3, etc. Some models will display
both the selected gear limit, and the actual current
gear, while in AutoStick mode.

Transmission Gear Selector

Gear Ranges
Do not press the accelerator pedal when shifting
from PARK (P) or NEUTRAL (N) into another gear
range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before acceler -
ating. This is especially important when the engine
is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use PARK
while the vehicle is in motion. Apply the parking
brake when exiting the vehicle in this range.
When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb
on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition OFF.
Remove the key fob from the vehicle.
NOTE:On four-wheel drive vehicles be sure that the
transfer case is in a drive position. The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, rotate the shifter all
the way counterclockwise until the indicator
displays PARK.
Look at the transmission gear position display
and verify that it indicates the PARK position (P),
and is not blinking.
With the 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.
CAUTION!
Before moving the transmission gear selector
out of PARK, you must start the engine, and
also press the brake pedal. Otherwise,
damage to the gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.

23_WL_OM_EN_USC_t.book Page 128

130STARTING AND OPERATING
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.

AutoStick Paddle Shifters
Operation
To activate AutoStick mode, tap one of the paddle
shifters on the steering wheel. Tapping the (-)
paddle shifters to enter AutoStick mode will
downshift the transmission to the next lower gear,
while tapping (+) to enter AutoStick mode will
retain the current gear. The current transmission
gear will be displayed in the instrument cluster. In
AutoStick mode, you can use the paddle shifters,
to manually shift the transmission. Tapping the (-)
paddle shifters, will downshift the transmission to
the next lower gear. Tapping the (+) paddle
shifters, will upshift the transmission to the next
highest gear.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition
would result. It will remain in the selected gear
until another upshift or downshift is chosen, except
as follows.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans
-
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the (-) paddle pressed, will downshift
the transmission to the lowest gear possible at
the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected. The
vehicle will force an upshift, but it will stay in
AutoStick mode.
To disengage AutoStick mode, push and hold the
(+) paddle shifters until "D" is once again indicated
in the instrument cluster. You can shift in or out of
AutoStick mode at any time without taking your
foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
