DRIVER ADJUSTABLE PEDALS — 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 pedals cannotbe adjusted when the vehicle is in 
R (Reverse) or when the Speed Control is SET.

Electrical Disturbances
Radio waves may pick up electrical disturbances during 
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio. 
NOTE: The radio, steering wheel radio controls (if 
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

CAUTION!
If oil pressure falls to less than normal readings, shut 
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
Do Not Operate The Engine With Failed Parts
Practically all failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:
•engine misfiring or vibrating severely
•sudden loss of power
•unusual engine noises
•fuel, oil or coolant leaks
•sudden change, outside the normal operating range, in
the engine operating temperature
•excessive smoke
•oil pressure drop
TRANSMISSION SHIFTING 
Automatic Transmission with Overdrive— If 
Equipped
The gear shift selector display, located in the instrument
panel cluster, indicates the transmission gear range (the
selector is illuminated for night driving). The selector
lever is mounted on the right side of the steering column.
You must depress the brake pedal, to pull the selector
lever out of park (P) position (Brake Interlock System). To
drive, move the selector lever from Park or Neutral to the
desired drive position. Pull the selector lever toward you
when shifting into Reverse, Second, First or Park, or
when shifting out of Park.

ABS Warning Light
The Anti-lock Brake System includes an amber warning 
light, located in the instrument cluster. When the light is
illuminated, the Anti-lock Brake System is not function-
ing. The system reverts to standard non-anti-lock brakes.
WARNING!
Pumping of the anti-lock brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost. 
If for some reason, the power assist is interrupted, it will 
still be possible to steer your vehicle. Under these condi-
tions you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers. 
NOTE: Increased noise levels at the end of the steering 
wheel travel are considered normal and does not indicate
that there is a problem with the power steering system. 
Upon initial start-up in cold weather, the power steering 
pump may make noise for a short period of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and does not in any
way damage the steering system.

        Page 295 of 496
WARNING!
Continued operation with reduced power steering 
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolong operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and should be avoided when
possible. Damage to the power steering pump may
occur.
TIRE SAFETY INFORMATION 
Tire Markings
NOTE:
•P (Passenger)-Metric tire sizing is based on U.S. design 
standards. P-Metric tires have the letter “P” molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
