located behind the glove box door. You
can also unlock the trunk by pressing

See Section 3 of your Owner Manual.
Trunk Storage

usable trunk space and will not crush

Restraint System for Children
(LATCH)
Your vehicle’s LATCH system provides
quick and easy installation of child seats

uses six anchors on the rear seat with
locations marked on the seatback.
In addition, a top strap anchor is located
behind the rear seat filler panel. In order
to get to the bracket, you must open the
trim cover.
See Section 1 of your Owner Manual.
Trip Odometer
In addition to a mileage odometer, your
vehicle has a trip odometer that informs
you how far you’ve traveled on weekend
trips, back and forth to work, or any-
where else you happen to drive. It is
located in the same place as your
mileage odometer.
To display it, press and release the
black stem located on the right side of
your instrument cluster. To set the trip
odometer to zero, press and hold the
black stem for at least two seconds.
To recall the mileage odometer, press
and release the black stem again.

Dual Climate Control System
This system controls the heating, cool-
ing and ventilation of your vehicle.
The left knob operates the fan and pro-
vides five speed settings ranging from
LO to HI. The knob on the right offers
six operating modes:
MAX:(Maximum Air Conditioning)
VENT:(Ventilation)
BI-LEVEL:(Bi-Level)
HTR:(Heater)
BLEND:This mode directs half of the air
to the floor outlets and half to the
defroster and side window outlets.
DEF:This mode directs most of the air
through the defroster and the side win-
dow outlets.
Air Conditioning and Rear Defogger
The two buttons located at the bottom of
the climate control system faceplate
control the air conditioning and the rear
window defogger:
AC:Press this button to turn the air con-
ditioning on and off. An indicator light
above the button will illuminate when the
system is on.REAR:Press this button to turn the rear
window defogger on. The defogger will
shut off automatically after about 15
minutes.
Individual Temperature Control
The driver and front passenger can
select their own air temperatures.
DRIVER:The lever on the left adjusts
the temperature for the driver’s side out-
lets. Slide the lever up to raise the tem-
perature and down to lower the temper-
ature.
PASSENGER:The lever on the right
adjusts the temperature for the passen-
ger’s side outlets. Slide the lever up to
raise the temperature and down to lower
the temperature.
See Section 3 of your Owner Manual.
Antilock Brakes (ABS)
(if equipped)
Your vehicle is equipped with an antilock
brake system (ABS), an advanced elec-
tronic brake system that will help pre-
vent a braking skid. When you start your
engine or begin to drive away, you may
hear a slight noise or feel a brake pedal
vibration — this is normal; the system is
simply checking itself.
Using Antilock Brakes:
•Never pump your brakes. Just hold
the brake pedal down firmly and
steer.
•You may feel a slight pedal pulsation
or notice some noise — that’s OK
— it means your ABS is working
properly.
See Section 4 of your Owner Manual.
