SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 87for more information about
modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several
places around your vehicle. You do not want the
system to inate while someone is working on your
vehicle. Your dealer/retailer and the service manual
have information about servicing your vehicle and
the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 498.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. They are probably part
of the airbag system. Be sure to follow
proper service procedures, and make sure
the person performing work for you is
qualied to do so.
The airbag system does not need regular
maintenance.
86

If you lose or damage your PASS-Key®III+ key,
see your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the
vehicle.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake, or slow,
the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
the new brake linings are not 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.
Do not tow a trailer during break-in. See
Towing a Trailer on page 342for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load can
be gradually increased.
117

Automatic Transaxle Operation
The automatic transaxle may have a shift lever
located either on the steering column or on
the console between the seats.
There are several different positions for the shift
lever.
PARK (P):This position locks the front wheels. It
is the best position to use when you start the
engine because your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not 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 will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P). See
Shifting Into Park (P) on page 126.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 342.
122

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
The transaxle will shift down to the next gear
and have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 317.
Notice:Driving your vehicle if you notice that it
is moving slowly or not shifting gears as you
increase speed may damage the transaxle. Have
your vehicle serviced right away. You can drive
in SECOND (2) when you are driving less than
35 mph (55 km/h) and DRIVE (D) for higher
speeds until then.DRIVE (D) can be used for towing. You may want
to shift the transaxle to THIRD (3) or, if necessary,
to a lower gear if the transaxle shifts too often under
heavy loads and/or hilly conditions.
SeeTowing a Trailer on page 342for more
information.
THIRD (3):This position is also used for normal
driving. However, it reduces vehicle speed
more than DRIVE (D) without using your brakes.
You might choose THIRD (3) instead of DRIVE (D)
when driving on hilly, winding roads, when
towing a trailer, so there is less shifting between
gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed
more than THIRD (3) without using your brakes.
You can use SECOND (2) on hills. It can help
control your speed as you go down steep mountain
roads, but then you would also want to use your
brakes off and on.
Notice:Do not shift into SECOND (2) unless
you are going slower than 65 mph (105 km/h), or
you can damage your engine and/or transaxle.
124

A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle speed is
greater than 5 mph (8 km/h). The brake light
will come on and stay on until the parking brake is
released. SeeBrake System Warning Light on
page 229for more information.
To release the parking brake, hold the regular
brake pedal down with your right foot and push the
parking brake pedal down with your left foot.
When you lift your left foot, the parking brake pedal
will follow it to the released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 342.Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 342.
126

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 130.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 328.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not 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 will not move,
even when you are on fairly level ground,
always set the parking brake after you
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 126.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 342.
131

Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
speed, vehicle load, traffic conditions and the
steepness of the hills. It may not detect a vehicle
in your lane while driving on hills. When going up
steep hills, you may want to use the accelerator
pedal to maintain your vehicle’s speed. When going
downhill, especially when towing a trailer, you may
want to brake to keep your speed down. Applying
the brake disengages the system. You may choose
not to use Adaptive Cruise Control on steep hills,
especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
When you press the Adaptive Cruise Control
button or turn the ignition off, the set speed
memory is erased.
Other Messages
There are three additional messages that may
appear on the DIC. They are SERVICE RADAR
CRUISE, RADAR CRUISE NOT READY and
CLEAN RADAR. These messages will appear
to indicate a problem with the Adaptive Cruise
Control. SeeDIC Warnings and Messages
on page 246for more information.
Cleaning the System
The radar can become blocked by snow, ice, or
dirt. If so, you may need to turn off the engine and
clean the lens. Remember, do not use Adaptive
Cruise Control in icy conditions, or when visibility
is low, such as in fog, rain or snow.
The emblem/lens is located in the center of
the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to
engage the Adaptive Cruise Control. If you
are unable to do so, see your dealer.
192

When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull
off the road and stop carefully. You may notice that
the pedal is harder to push, or the pedal may go
closer to the oor. It may take longer to stop.
If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 340.
{CAUTION:
Your brake system may not be working
properly if the brake system warning
light is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will
come on when your
engine is started
and may stay on for
several seconds.
That is normal.
If the ABS warning light comes on and stays on,
there may be a problem with the antilock portion
of the brake system. If the red BRAKE light is
not on, you still have brakes, but you do not have
antilock brakes. SeeBrake System Warning
Light on page 229.
If the light stays on, turn the ignition to OFF or
ACCESSORY. If the light comes on when you are
driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on
again while you are driving, your vehicle needs
service. If the regular brake system warning light
is not on, you still have brakes, but you do not
have anti-lock brakes.
230

This light should come on, as a check to show
you it is working, when the ignition is on and
the engine is not running. If the light does
not come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis
and service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may be
required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park your
vehicle. Turn the key off, wait at least 10 seconds
and restart the engine. If the light remains on
steady, see “If the Light Is On Steady” following.
If the light is still ashing, follow the previous steps,
and see your dealer for service as soon as
possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 358.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into
the atmosphere. A few driving trips with the cap
properly installed should turn the light off.
