GETTING TO KNOW YOUR VEHICLE23
If you push the power door lock switch while the ignition is
in the ON/RUN position, and any door or the liftgate is
open, the power locks will not operate. This prevents you
from accidentally locking the key fob in the vehicle.
Placing the ignition in the OFF position or closing the doors
and liftgate will allow the locks to operate.
KEYLESS ENTER ‘N GO™ — PASSIVE
E
NTRY
The Passive Entry system is an enhancement to the
vehicle’s Remote Keyless Entry system and a feature of
Keyless Enter ‘n Go™ — Passive Entry. This feature allows
you to lock and unlock the vehicle’s door(s) without having
to push the key fob lock or unlock buttons.
NOTE:
 Passive Entry may be programmed on/off through
Uconnect Settings Úpage 130.
 The key fob may not detect the Passive Entry system if
it is located next to a mobile phone, laptop or other
electronic device; these devices may block the key
fob’s wireless signal and prevent the Passive Entry
system from locking and unlocking the vehicle.
 If wearing gloves, if it has been raining/snowing, or
there is salt/dirt covering the Passive Entry door
handle, the unlock sensitivity can be affected, resulting
in a slower response time.
 The doors may unlock when water is sprayed on the
Passive Entry door handles, if the key fob is located
outside of the vehicle within 5 ft (1.5 m) of the handle.
 If the vehicle is unlocked by Passive Entry and no door
is opened within 60 seconds, the vehicle will relock
and, will arm the Vehicle Security system (if equipped). To Unlock From The Driver's Side Or Passenger’s Side
With a valid Passive Entry key fob within 5 ft (1.5 m) of
either front door handle, grab the door handle to unlock
the door automatically.
Grab The Door Handle To Unlock


Either the driver door only or all doors will unlock when
you grab hold of the front driver’s door handle,
depending on the selected setting in the Uconnect
system
Úpage 130.
 All doors and the liftgate will unlock when the front
passenger door handle is grabbed regardless of the
driver’s door unlock preference setting.
Frequency Operated Button Integrated Key (FOBIK-Safe)
To minimize the possibility of unintentionally locking a
Passive Entry key fob inside your vehicle, the Passive Entry
system is equipped with an automatic door unlock feature
which will function if the ignition switch is in the OFF
position. There are three situations that trigger a FOBIK-Safe search
in any Passive Entry vehicle:

A lock request is made by a valid Passive Entry key fob
while a door is open.
 A lock request is made by the Passive Entry door
handle while a door is open.
 A lock request is made by the door panel switch while
the door is open.
When any of these situations occur, after all open doors
are shut, the FOBIK-Safe search will be executed. If it
detects a Passive Entry key fob inside the vehicle and it
does not detect any Passive Entry key fobs outside the
vehicle, then the vehicle will unlock and alert the
customer.
NOTE:The vehicle will only unlock the doors when a valid Passive
Entry key fob is detected inside the vehicle. The vehicle will
not unlock the doors when any of the following conditions
are true:
 The doors are manually locked using the door lock
knobs.
 Three attempts are made to lock the doors using the
door panel switch and then the doors are closed.
 There is a valid Passive Entry key fob outside the
vehicle and within 5 ft (1.5 m) of either Passive Entry
door handle.

Cargo tie-down loops are located on the trim panels.
WARNING!
Cargo tie-downs are not safe anchors for a child seat
tether strap. In a sudden stop or accident, a tie-down
could pull loose and allow the child seat to come
loose. A child could be badly injured. Use only the
anchors provided for child seat tethers.
 To help protect against personal injury, passengers
should not be seated in the rear cargo area. The rear
cargo space is intended for load carrying purposes
only, not for passengers, who should sit in seats and
use seat belts.The weight and position of cargo and passengers can
change the vehicle center of gravity and vehicle
handling. To avoid loss of control resulting in personal
injury, follow these guidelines for loading your vehicle:
Do not carry loads that exceed the load limits
described on the label attached to the left door or
left door center pillar.
 Always place cargo evenly on the cargo floor. Put
heavier objects as low and as far forward as possible.
 Place as much cargo as possible in front of the rear
axle. Too much weight or improperly placed weight
over or behind the rear axle can cause the vehicle to
sway.
 Do not pile luggage or cargo higher than the top of
the seatback. This could impair visibility or become a
dangerous projectile in a sudden stop or accident.
