Remote Vehicle Start
This vehicle may have a remote start
feature. This feature allows you to start the
engine from outside the vehicle. It may also
start the vehicle's heating or air conditioning
systems. See Climate Control Systems 0114.
Laws in some local communities may restrict
the use of remote starters. For example,
some laws may require a person using remote start to have the vehicle in view
when doing so. Check local regulations for
any requirements on remote starting of
vehicles.
Do not use the remote start feature if the
vehicle is low on fuel. The vehicle may run
out of fuel.
The RKE transmitter range may be less while
the vehicle is running.
Other conditions can affect the performance
of the transmitter. See
Remote Keyless Entry
(RKE) System 08.
/:This button will be on the RKE
transmitter if the vehicle has remote start.
To start the engine using the remote start
feature:
1. Press and release
Qon the transmitter.
2. Immediately press and hold
/until the
turn signal lamps flash. If you cannot see
the lamps, press and hold
/for at least
four seconds.
When the engine starts, the parking
lamps will turn on and remain on while
the engine is running. The doors will be
locked. The engine will continue to run for
10 minutes. After 30 seconds, repeat the
steps if a 10-minute extension is desired.
Remote start can be extended only once.
After entering the vehicle during a remote
start, turn the ignition on to drive the
vehicle.
A maximum of two remote starts or a start
with an extension are allowed between
ignition cycles.
If the remote start procedure is used again
before the first 10-minute time frame has
ended, the first 10 minutes will immediately
expire and the second 10-minute time frame
will start.
After the engine has been remote started
two times or a start with an extension, the
ignition must be turned on and then off
before the remote start procedure can be
used again.
To cancel a remote start do any of the
following:
.Press and hold/until the parking lamps
turn off.
.Turn on the hazard warning flashers.
.Turn the ignition on and then off.

Seats and Restraints 33
Squeeze both sides of the release button
and pull outward. Then move the height
adjuster up or down to the desired position
and release the button.
After the adjuster is set to the desired
position, try to move it up or down without
squeezing the release button to make sure it
has locked into position.
Seat Belt Pretensioners
If the vehicle has seat-mounted side impact
airbags and roof-rail airbags, it also has seat
belt pretensioners for the front outboard
occupants.
Although the seat belt pretensioners cannot
be seen, they are part of the seat belt
assembly. They can help tighten the seat
belts during the early stages of a moderate
to severe frontal, near frontal, or rear crash
if the threshold conditions for pretensioner
activation are met. And, if the vehicle has
roof-rail airbags, seat belt pretensioners can
help tighten the seat belts in a side crash or
a rollover event.Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other parts of
the vehicle’s seat belt system will need to
be replaced. See
Replacing Seat Belt System
Parts after a Crash 035.
Do not sit on the outboard seat belt while
entering or exiting the vehicle or at any
time while sitting in the seat. Sitting on the
seat belt can damage the webbing and
hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may provide
added seat belt comfort for older children
who have outgrown booster seats and for
some adults. When installed on a shoulder
belt, the comfort guide positions the
shoulder belt away from the neck and head.
Comfort guides are available through your
dealer for the rear outboard seating
positions. Instructions are included with the
comfort guides.
Seat Belt Use During Pregnancy
Seat belts work for everyone, including
pregnant women. Like all occupants, they
are more likely to be seriously injured if
they do not wear seat 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.

42 Seats and Restraints
Canada and Mexico
This switch should only be turned to the
OFF position if the person in the front
outboard passenger position is a member of
a passenger risk group identified by the
national government as follows:
Infant. An infant (less than 1 year old) must
ride in the front seat because:
.My vehicle has no rear seat;
.My vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
.The infant has a medical condition which,
according to the infant's physician, makes
it necessary for the infant to ride in the
front seat so that the driver can
constantly monitor the child's condition. Child age 1 to 12. A child age 1 to 12 must ride
in the front seat because:
.My vehicle has no rear seat;
.Although children ages 1 to 12 ride in the
rear seat(s) whenever possible, children
ages 1 to 12 sometimes must ride in the
front because no space is available in the
rear seat(s) of my vehicle; or
.The child has a medical condition which,
according to the child's physician, makes
it necessary for the child to ride in the
front seat so that the driver can
constantly monitor the child's condition.
Medical Condition. A passenger has a
medical condition which, according to his or
her physician:
.Causes the passenger airbag to pose a
special risk for the passenger; and
.Makes the potential harm from the
passenger airbag in a crash greater than
the potential harm from turning off the
airbag and allowing the passenger, even if
belted, to hit the instrument panel or
windshield in a crash.
{Warning
If the front outboard passenger frontal
airbag is turned off for a person who is
not in a risk group identified by the
national government, that person will not
have the extra protection of an airbag. In
a crash, the airbag will not be able to
inflate and help protect the person sitting
there. Do not turn off the front outboard
passenger frontal airbag unless the
person sitting there is in a risk group.

Instruments and Controls 75
When the engine is not running, but the
ignition is on, this gauge shows the
battery's state of charge in DC volts.
When the engine is running, the gauge
shows the condition of the charging system.
Readings between the low and high warning
zones indicate the normal operating range.
Readings in the low warning zone may occur
when a large number of electrical
accessories are operating in the vehicle and
the engine is left at an idle for an extended
period. This condition is normal since the
charging system is not able to provide full
power at engine idle. As engine speeds are
increased, this condition should correct itself
as higher engine speeds allow the charging
system to create maximum power.
The vehicle can be only driven for a short
time with the reading in either warning
zone. If it must be driven, turn off all
unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system.
Have the vehicle serviced as soon as
possible.Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a seat belt reminder light on the
instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt. Then the
light stays on solid until the belt is buckled.
This cycle may continue several times if the
driver remains or becomes unbuckled while
the vehicle is moving.
If the driver seat belt is buckled, neither the
light nor the chime comes on.
Airbag Readiness Light
This light shows if there is an electrical
problem with the airbag system. It is
located in the instrument cluster. The
system check includes the airbag sensor(s),
the airbag on-off switch, the pretensioners
(if equipped), the airbag modules, thewiring, and the crash sensing and diagnostic
module. For more information on the airbag
system, see
Airbag System 035.
The airbag readiness light comes on for
several seconds when the vehicle is started.
If the light does not come on then, have it
fixed immediately.
{Warning
If the airbag readiness light stays on
after the vehicle is started or comes on
while driving, it means the airbag system
might not be working properly. The
airbags in the vehicle might not inflate in
a crash, or they could even inflate
without a crash. To help avoid injury,
have the vehicle serviced right away.
If there is a problem with the airbag
system, a Driver Information Center (DIC)
message may also come on.

such as the radio and air conditioner. Find a
safe place to stop the vehicle.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s emission
control on-board diagnostic system. If this
light is on while the engine is running, a
malfunction has been detected and the
vehicle may require service. The light should
come on to show that it is working when
the ignition is on and the engine is not
running. SeeIgnition Positions 0130.
Malfunctions are often indicated by the
system before any problem is noticeable.
Being aware of the light and seeking service
promptly when it comes on may prevent
damage.
Caution
If the vehicle is driven continually with
this light on, the emission control system
may not work as well, the fuel economy
may be lower, and the vehicle may not

run smoothly. This could lead to costly
repairs that might not be covered by the
vehicle warranty.
Caution
Modifications to the engine, transmission,
exhaust, intake, or fuel system, or the
use of replacement tires that do not
meet the original tire specifications, can
cause this light to come on. This could
lead to costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0173.
If the light is flashing : A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required.
