3-8 Seats and Restraints
Memory Seats
On vehicles with the memory
feature, the“1”and “2”buttons on
the outboard side of the driver seat
are used to manually save and
recall the driver seat and outside
mirror positions. These manually
stored positions are referred to as
Button Memory positions. The vehicle will also automatically
save driver seat and outside mirror
positions to the current driver
Remote Keyless Entry (RKE)
transmitter when the ignition is
placed in OFF. These automatically
stored positions are referred to as
RKE Memory positions. See
Remote Keyless Entry (RKE)
System Operation on page 2‑4
for
more information.
Storing Button Memory Positions
To save positions into Button
Memory:
1. Adjust the driver seat, seatback recliner, and both outside mirrors
to the desired driving positions.
2. Press and hold MEM (Memory) and “1”at the same time until a
beep sounds.
3. Repeat Steps 1 and 2 for a second driver using “2.”Recalling Button Memory
Positions
To recall the manually saved Button
Memory positions, press and hold
“1”
or“2.” The driver seat and
outside mirrors move to the
positions stored to those buttons
when pressed. Releasing “1”or“2”
before the stored positions are
reached stops the recall.
If something has blocked the driver
seat while recalling a memory
position, the recall may stop.
Remove the obstruction; then press
and hold the appropriate manual
control for the memory item that is
not recalling for two seconds. Try
recalling the memory position again
by pressing the appropriate memory
button. If the memory position is still
not recalling, see your dealer for
service.

Recalling RKE Memory Positions
(Memory Remote Recall)
The Memory Remote Recall feature
can recall the driver seat and
outside mirrors to previously stored
RKE Memory positions when
entering the vehicle.
Every time the ignition is placed in
OFF, the positions of the driver seat
and outside mirrors are
automatically stored to the RKE
transmitter that was used to start
the vehicle. These positions are
called RKE Memory positions and
may be different than the previously
mentioned Button Memory positions
saved to the“1”or“2” buttons. To
automatically recall RKE Memory
positions, unlock the driver door
with the RKE transmitter, and open
the driver door. On vehicles with
Keyless Access, opening the driver
door when an RKE transmitter is
present will activate the RKE
Memory recall. If the driver door is
already open, pressing the RKE
transmitter Kbutton will also
activate the RKE Memory recall. The driver seat and outside mirrors
will move to the previously saved
RKE Memory positions.
This feature is turned on or off using
the vehicle personalization menu.
See
Vehicle Personalization on
page 5‑43 for more information.
To stop recall movement, press one
of the memory, power mirror,
or power seat controls.
If something has blocked the driver
seat while recalling a memory
position, the recall may stop.
Remove the obstruction; then press
and hold the appropriate manual
control for the memory item that is
not recalling for two seconds. Try
recalling the memory position again
by opening the driver door and
pressing the RKE transmitter K
button. If the memory position is still
not recalling, see your dealer for
service. Easy Exit Driver Seat
This feature moves the seat
rearward allowing the driver more
room to exit the vehicle.
To activate, place the ignition in
OFF and open the driver door. If the
driver door is already open, placing
the ignition in OFF will activate the
easy exit driver seat.
This feature is turned on or off using
the vehicle personalization menu.
See
Vehicle Personalization on
page 5‑43 for more information.
To stop recall movement, press one
of the memory or power seat
controls.
If something has blocked the driver
seat while recalling the exit position,
the recall may stop. Remove the
obstruction; then press and hold the
power seat control rearward for
two seconds. Try recalling the exit
position again. If the exit position is
still not recalling, see your dealer for
service.

Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer
to have it repaired. Torn or frayed
safety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. See
Safety Belt
Reminders on page 5‑15 for more
information.
Keep safety belts clean and dry.
See Safety Belt Care on page 3‑21.

If the word OFF is lit on the airbag
status indicator, it means that the
passenger sensing system has
turned off the front outboard
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5‑16 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, to produce
a cleaner environment.
This light comes on when the
vehicle is placed in ON/RUN for key
access or Service Only Mode for
keyless access, as a check to show
it is working. If it does not, have the
vehicle serviced by your dealer. See
Ignition Positions (Key Access) on
page 9‑18 orIgnition Positions
(Keyless Access) on page 9‑20 for
more information.

The following may correct an
emissions system malfunction:
.Check that the fuel cap is fully
installed. SeeFilling the Tank on
page 9‑55. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up. If one or more of these conditions
occurs, change the fuel brand used.
It will require at least one full tank of
the proper fuel to turn the light off.
See
Recommended Fuel on
page 9‑53.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Some local governments may have
programs to inspect the on-vehicle
emission control equipment. For the
inspection, the emission system test
equipment is connected to the
vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel next to the steering wheel.
See your dealer if assistance is
needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is running.
The vehicle is in ON/RUN for
keyed access, or service only
mode for keyless access and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
