Overview
If equipped, the memory seat feature allows
drivers to save their unique driving positions
and a shared exit position. See“Saving
Seating Positions” later in this section. The
saved positions can be recalled manually by
all drivers, see “Manually Recalling Seating
Positions” later in this section, and drivers
with remote key 1 and 2 can also recall
them automatically. See “Auto Seat Entry
Memory Recall” or“Auto Seat Exit Memory
Recall” later in this section. To enable
automatic recalls, turn on Seat Entry
Memory and/or Seat Exit Memory. See
“Enabling Automatic Recalls” later in this
section. The memory recalls may be
canceled at any time during the recall. See
“Cancel Memory Seating Recalls” later in this
section.
Identifying Driver Number
The vehicle identifies the current driver by
their remote key number 1–8. The current
remote key number may be identified by
Driver Information Center (DIC) welcome
message, “You are driver x for memory recalls.”
This message is displayed the first
few times the vehicle is turned on when a
different remote key is used. For Seat Entry
Memory to work properly, save positions to
the 1 or 2 memory button matching the
driver number of this welcome message. To
aid in identifying remote key IDs, it is
recommended to only carry one remote key
when entering the vehicle. Perform the
following if the welcome message is not
displayed:
1. Move all keys and remote keys away from the vehicle.
2. Start the vehicle with another remote key. A DIC welcome message should
display indicating the driver number of
the other remote key. Turn the vehicle
off and remove the other key or remote
key from the vehicle.
3. Start the vehicle with the initial key or remote key. The DIC welcome message
should display the driver number of the
initial remote key. Saving Seating Positions
Read these instructions completely before
saving memory positions.
To save preferred driving positions to
1 and 2:
1. Turn the vehicle on or to accessory mode. A DIC welcome message may
indicate the driver number of the current
remote key. See “Identifying Driver
Number” previously in this section.
2. Adjust all available memory features to the desired driving position.
3. Press and release SET; a beep will sound.
4. Immediately upon releasing SET, press and hold memory button 1 or 2 matching
the current remote key number until two
beeps sound. If too much time passes
between releasing SET and pressing 1 or
2, the two beeps will not sound
indicating memory position were not
saved. Repeat Steps 3 and 4 to try again.
5. Repeat Steps 1–4 for the other remote key 1 or 2 using the other 1 or 2 memory
button.
It is recommended to save the preferred
driving positions to both 1 and 2 if you are
the only driver.

that there may be something in the
rear seat.
The feature is active only once each time
the vehicle is turned on and off, and will
require reactivation by opening and closing

Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after acrash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection.
Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature delays the vehicle
from shifting out of P (Park) when the driver
seat belt is not buckled. The Buckle to Drive
feature must be turned ON in the
infotainment system to work. To turn the
Buckle to Drive feature on or off, select
Settings > Vehicle > Buckle to Drive. See
Teen Driver 0185, if equipped. If the vehicle is on and the brake pedal is
pressed with the vehicle in P (Park) but the
driver seat belt is not buckled, a message
displays in the Driver Information
Center (DIC) and the vehicle will be delayed
from shifting out of P (Park). Buckle the
driver seat belt to clear the message and
shift out of P (Park). Shifting from P (Park)
will be delayed once for each time the
vehicle is started.
For some fleet vehicles, the feature is
always ON and cannot be turned OFF in the
infotainment system. The vehicle will be
delayed from shifting from P (Park) each
time the driver attempts to do so while the
driver seat belt is not buckled. Turning the
vehicle off then on will not change this
condition.
On some models, Buckle to Drive may also
delay shifting out of P (Park) if a front
passenger seat belt is unbuckled. A message
displays in the DIC. Buckle the front
passenger seat belt to shift out of P (Park).
This feature may delay the vehicle from
shifting out of P (Park) if an object, such as
a briefcase, handbag, grocery bag, laptop,
or other electronic device, is on the front
passenger seat. If this happens, remove the
object from the seat or buckle the seat belt
to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See
“Seat Belts”and“Child
Restraints” in the Index for information
about the importance of proper
restraint use.
If the driver seat belt or the front passenger
seat belt is unbuckled when driving, the seat
belt reminder chime and light(s) will come
on. See Seat Belt Reminders 0120. This
feature may not function properly if the
airbag readiness light is on. See Airbag
Readiness Light 0121.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children075 or
Infants and Young Children 076. Review
and follow the rules for children in addition
to the following rules.
