system on and off.
Turn this knob clockwise or counterclockwise to
increase or decrease the volume.
Speed Compensated Volume (SCV):The radio

4. Press the pushbutton under the desired Speed
Compensated Volume setting (OFF, Low, Med
(medium), or High) to select the level of radio
volume compensation. The display times out
after approximately 10 seconds. Each higher
setting allows for more radio volume
compensation at faster vehicle speeds.

Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
The RDS feature is available for use only on FM
stations that broadcast RDS information. This
system relies upon receiving specic information
from these stations and only works when the
information is available. While the radio is tuned to
an FM-RDS station, the station name or call letters
display. In rare cases, a radio station could
broadcast incorrect information that causes the
radio features to work improperly. If this happens,
contact the radio station.

the 48 contiguous United States and Canada.
XM™ offers a large variety of coast-to-coast
channels including music, news, sports, talk,
traffic/weather (U.S. subscribers), and children’s

Remember: ABS does not change the time you
need to get your foot up to the brake pedal
or always decrease stopping distance. If you get
too close to the vehicle in front of you, you will not
have time to apply your brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You may feel the brakes vibrate, or you may notice
some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Locking Rear Axle
If your vehicle has this feature, your locking rear
axle can give you additional traction on snow, mud,
ice, sand or gravel. It works like a standard axle
most of the time, but when one of the rear wheels
has no traction and the other does, this feature will
allow the wheel with traction to move the vehicle.
StabiliTrak®System
Your vehicle may be equipped with the
StabiliTrak®system which combines antilock
brake, traction and stability control systems and
helps the driver maintain directional control of the
vehicle in most driving conditions.
When you rst start your vehicle and begin to
drive away, the system performs several diagnostic
checks to ensure there are no problems. You
may hear or feel the system working. This
is normal and does not mean there is a problem
with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h). In
some cases, it may take approximately two
miles of driving before the system initializes.

So here are some tips for passing:
Drive ahead. Look down the road, to the
sides, and to crossroads for situations
that might affect your passing patterns. If you
have any doubt whatsoever about making
a successful pass, wait for a better time.
Watch for traffic signs, pavement markings,
and lines. If you can see a sign up ahead
that might indicate a turn or an intersection,
delay your pass. A broken center line
usually indicates it is all right to pass, providing
the road ahead is clear. Never cross a solid
line on your side of the lane or a double solid
line, even if the road seems empty of
approaching traffic.
Do not get too close to the vehicle you want
to pass while you are awaiting an opportunity.
For one thing, following too closely reduces
your area of vision, especially if you are
following a larger vehicle. Also, you will not
have adequate space if the vehicle ahead
suddenly slows or stops. Keep back a
reasonable distance.
When it looks like a chance to pass is coming
up, start to accelerate but stay in the right
lane and do not get too close. Time your moveso you will be increasing speed as the time
comes to move into the other lane. If the way
is clear to pass, you will have a running
start that more than makes up for the distance
you would lose by dropping back. And if
something happens to cause you to cancel
your pass, you need only slow down and drop
back again and wait for another opportunity.
If other vehicles are lined up to pass a slow
vehicle, wait your turn. But take care that
someone is not trying to pass you as you pull
out to pass the slow vehicle. Remember to
glance over your shoulder and check the
blind spot.
Check your vehicle’s mirrors, glance over your
shoulder, and start your left lane change signal
before moving out of the right lane to pass.
When you are far enough ahead of the passed
vehicle to see its front in your vehicle’s inside
mirror, activate the right lane change signal
and move back into the right lane. Remember
that, if your vehicle’s passenger side outside
mirror is convex, the vehicle you just passed
may seem to be farther away from you than it
really is.
