Six-Way Power Driver Seat
If your vehicle has this
feature, the control is
located on the outboard
side of the driver's
seat cushion.
To adjust the seat, do any of the following:
control toward the front or the rear.
Move the seat forward or rearward by sliding the
Raise or lower the seat cushion by sliding the
Raise or lower the front portion of the seat cushion
0 Raise or lower the rear portion of the seat cushion
control
up or down.
by sliding the front of the control up or down.
by sliding the rear of the control up or down.
Power Lumbar
If your vehicle is equipped with this feature, there will be
a control located on the outboard side of the driver's
seat cushion, in front of the reclining seatback lever.
To
increase or decrease lumbar support, push the control
forward or rearward.
To adjust the lumbar support up or
down, push the control up or down.
1-3

Never do this.
Here two children are wearing the same belt.
The belt can’t properly spread the impact
forces. In a crash, the two children can be crushed together and seriously injured.
A belt
must be used by only one person at a time.
Q: What if a child is wearing a lap-shoulder belt,
but the child
is so small that the shoulder belt
is very close to the child’s face or neck?
A: Move the child toward the center of the vehicle, but
be sure that the shoulder belt still is on the child’s
shoulder,
so that in a crash the child’s upper body
would have the restraint that belts provide. If the
child is sitting in a rear seat outside position, see
Rear Safety Belt Comfort Guides for Children
and
Small Adults on page 7-26. If the child is so small
that the shoulder belt is still very close to the child’s
face
or neck, you might want to place the child in the
center seat position, the one that has only
a lap belt.

When Should an Air Bag Inflate?
An air bag is designed to inflate in a moderate to severe
frontal, or near-frontal crash. The air bag will inflate
only
if the impact speed is above the system’s designed
“threshold level.”
If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level is
about
12 to 18 mph (19 to 29 km/h). The threshold
level can vary, however, with specific vehicle design,
so that it can be somewhat above or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will
be higher. The air bag is not designed to inflate
in
rollovers, rear impacts, or in many side impacts because
inflation would not help the occupant.
in any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
What Makes an Air Bag Inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in
a crash. The
sensing system triggers a release
of gas from the
inflator, which inflates the air bag. The inflator, air bag,
and related hardware are all part of the air bag
modules inside the steering wheel and
in the instrument
panel in front of the right front passenger.
How Does an Air Bag Restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the
protection provided by safety belts. Air bags distribute
the force of the impact more evenly over the occupant’s
upper body, stopping the occupant more gradually.
But air bags would not help you in many types of
collisions, including rollovers, rear impacts and many
side impacts, primarily because an occupant’s motion is
not toward those air bags. Air bags should never be
regarded as anything more than a supplement to safety
belts, and then only
in moderate to severe frontal or
near-frontal collisions.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features,
we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle has a theft-deterrent alarm system. A
red light located on top of the instrument panel,
toward the center of the vehicle and near the windshield,
will flash slowly when the system is armed.
While armed, the doors will not unlock with the power
door lock switch. The
alarm will souad if someone
tampers with the trunk lock, enters the vehicle without
using the remote keyless entry transmitter or key to
unlock the doors, or turns the ignition on. The horn will
sound and the headlamps will flash for up to two
minutes. The system will also cut
off the fuel supply,
preventing the vehicle from being driven.
Arming with the Power Lock Switch
Your alarm system can be programmed to arm when
you use either power lock switch to lock the
doors while
any door is open and the key is removed from the
ignition.
If you would like to arm the system with the
power lock switch, see Vehicle Personalization on
page
2-43. When programmed, the red light will flash
quickly to let you know that the system is ready to arm
with the power lock switches. When you press the
rear of a power door lock switch, the red light will stop
flashing and stay on to let you know that the system
is arming. After all the doors are closed and locked, the
red light will begin flashing at a very slow rate to let
you know the system
is armed.

Starting and Operating Your
Vehicle
New Vehicle Break-In Ignition Positions
With
the key in the ignition switch, you can turn it to
five different positions. The ignition switch is located
on the right side of the steering column.
Notice: Your vehicle doesn’t need an elaborate
“break-in.” But
it will perform better in the long
run if you follow these guidelines:
e
e
e Don’t drive at any one speed - fast or
slow
- for the first 500 miles (805 km).
Don’t make full-throttle starts.
Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken
in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Don’t tow a trailer during break-in.
See “Towing a Trailer”
in the Index for
more information. A
(ACCESSORY): This position lets
you use things like
the radio and windshield wipers while the engine is
off. To use accessory, push in the key and turn it toward
you. The steering wheel will stay locked.
3-1 9

Notice: If your key seems stuck in LOCK and you
can’t turn it, be sure you are using the correct key;
if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none
of these works,
then your vehicle needs service.
B (LOCK): This position locks the ignition, steering
wheel and transaxle. It’s a theft-deterrent feature. It’s also
the only position from which you can remove the key.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK. Use
OFF if you must have
the vehicle pushed or towed.
D (RUN): This position is where the key returns to after
you start the vehicle. With the engine
off, you can use
RUN to display some of the warning and indicator lights.
E (START): This position starts the engine.
A warning chime will sound
if you open the driver’s door
while the ignition is in
OFF, LOCK or ACCESSORY
and the key is in the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power, (RAP), the power
windows, audio system and sunroof will continue to work
up to
10 minutes after the ignition key is turned to
OFF and none of the doors are opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position - that’s a
safety feature. To restart while you’re already moving,
use NEUTRAL
(N) only.
Nofice: Don’t try to shift to PARK (P) if your
vehicle is moving.
If you do, you could damage the
transaxle. Shift to
PARK (P) only when your
vehicle is stopped.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to
do the following:
Prevent ignition key removal unless the shift lever is
in PARK (P) with the shift lever button fully released.
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than
OFF or
LOCK. The shift lock release is always functional
except in the case
of a dead or low voltage
(less than
9 V) battery.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
Maximum engine speed is limited when your vehicle is
in PARK
(P) or NEUTRAL (N) to protect driveline
components from improper operation.
There are several different positions for the shift lever.
PARK (P): This position locks the front wheels. It’s
the best position to
use when you start the engine
because the vehicle can’t move easily.
The automatic transaxle has a shift lever on the console
between the seats. There is also a display of the gear
positions on the instrument panel cluster near the
speedometer and tachometer.
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to. If you have left the
engine running,
the vehicle can move suddenly.
You
or others could be injured. To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the
shift lever to PARK (P). See “Shifting
Into Park (P)”
in the Index. If you’re pulling a
trailer, see “Towing a Trailer”
in the Index.
