highest setting. See Climate
Control System in the Index.
For more information about

Exhaust on page 8‑34.
Notice: If you open the liftgate
without checking for overhead
obstructions such as a garage
door, you could damage the
liftgate or the liftgate glass.

area above and behind the liftgate
is clear before opening it.

How to Detect a Tamper
Condition

on page 4‑33for
additional information.
Immobilizer
See Radio Frequency Statementon
page 12‑16for information
regarding Part 15 of the Federal
Communications Commission (FCC)
Rules and RSS-210/211 of Industry
Canada.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the key is
removed from the ignition.

1-14 Keys, Doors and Windows
The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches
an immobilizer control unit in the
vehicle and automatically disarms
the system. Only the correct key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.If the engine does not start and the
security light stays on there is a
problem with the system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged
or the light continues to stay on, try
another ignition key. If the engine
does not start with the other key, the
vehicle needs service. If the vehicle
does start, the first key may be
damaged. See your dealer/retailer
who can service the theft-deterrent
system and have a new key made.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

3. Push the latch plate into thebuckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender
on page 2‑23.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary. 4. If equipped with a shoulder belt
height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
later in this section for
instructions on use and
important safety information.
5. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
To unlatch the belt, push the button
on the buckle. For outboard seating
positions, slide the latch plate up
the safety belt webbing when the
safety belt is not in use. The latch
plate should rest on the stitching on
the safety belt, near the guide loop.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.

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/retailer 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 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/
retailer 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.
