bags to inflate, it signals the inflators on the crash side of
the vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the side pillar molding out of the way and covers
the window. The airbag inflates in about 30 milliseconds
(about one-quarter of the time it takes to blink your eyes)
with enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies to
children. The window bag is only about 3
1¤2inches (8.9
cm) thick when it is inflated.
Enhanced Accident Response System
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 10 seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
Maintaining Your Airbag Systems
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.

DRIVER ADJUSTABLE PEDALS Ð IF EQUIPPED
The power adjustable accelerator and brake pedals allow
the driver to establish a comfortable position relative to
the steering wheel and pedals.
Adjustment
1. Position the driver seat so that you are at least 10
inches (254 mm) away from the airbag located in the
center of the steering wheel.
2. Fasten and adjust the seatbelts.
3. Move the adjustable pedal switch, located to the left of
the steering column near the parking brake release, in the
direction you desire to move the pedals.
4. The pedalscannotbe adjusted when the vehicle is in
R (Reverse) or when the Speed Control is SET.

200 STARTING AND OPERATING
Page 231 of 429

3500 Dual Rear Wheel Models Only
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering oil reaches
operating temperature.
Brake Noise
During normal operation of the brake system certain
noises may be present from time to time. Occasional
9groan9or9squeal9noises may occur during normal
operation of the brake system which may not be indica-
tive of a problem. These noises may be heard at any time
the brakes are applied but may be more noticeable during
the first few brake applications in the morning. Moisture,
hot or cold temperature, dust, and or other debris mayalso contribute to the noise condition. Repeated or con-
tinuous noises during braking may be an indication that
the brake linings are worn and in need of replacement.
Rear Wheel Anti-Lock Brake System Ð RWAL
The Anti-lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically controls the opera-
tion of the rear brakes to prevent rear wheel lockup.
The system remains operational in the four-wheel drive
mode. The level of performance is reduced when the
front brakes are locked up. This may cause the rear
brakes to lockup through the drivetrain, which may
reduce the effectiveness of the Anti-lock Brake System.
During severe braking conditions, particularly with
changing road surfaces, such as ice to concrete, a slight
drop or minor pulsation may be felt in the brake pedal.

POWER STEERING
Your power steering system will provide mechanical
steering capability if power assist is lost.
If for any reason the hydraulic pressure is interrupted, it
will still be possible to steer your vehicle. Under these
conditions you will experience a substantial increase in
steering effort.
TIRE SAFETY INFORMATION
Tire Markings
NOTE:
²P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter ªPº molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
