XM™ Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United States,
and in Canada. Just as with FM, tall buildings or hills can
interfere with satellite radio signals, causing the sound to
fade in and out. In addition, traveling or standing under
heavy foliage, bridges, garages, or tunnels may cause
loss of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when making
or receiving phone calls, charging the phone’s battery,
or simply having the phone on. This interference causes
an increased level of static while listening to the radio.
If static is received while listening to the radio, unplug
the cellular phone and turn it off.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged as long as it is securely attached
to the base. If the mast becomes slightly bent, straighten
it out by hand. If the mast is badly bent, replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand until fully seated plus one quarter turn.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof
or the rear of the vehicle. Keep the antenna clear
of obstructions for clear radio reception.

Braking
SeeBrake System Warning Light on page 3-29.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it is reaction time.
Average reaction time is about three-fourths of a second.
But that is only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second, a
vehicle moving at 60 mph (100 km/h) travels 66 feet
(20 m). That could be a lot of distance in an emergency,
so keeping enough space between the vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of the brakes; the weight of
the vehicle; and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is a
mistake. The brakes might not have time to cool between
hard stops. The brakes will wear out much faster with a
lot of heavy braking. Keeping pace with the traffic andallowing realistic following distances eliminates a lot of
unnecessary braking. That means better braking and
longer brake life.
If the engine ever stops while the vehicle is being driven,
brake normally but do not pump the brakes. If the brakes
are pumped, the pedal could get harder to push down.
If the engine stops, there will still be some power brake
assist but it will be used when the brake is applied. Once
the power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modifications
on page 5-3.
Antilock Brake System (ABS)
The vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that helps
prevent a braking skid.
If the vehicle has ABS,
this warning light on the
instrument panel comes on
briey when the vehicle is
started.
4-4

When the engine is started, or when the vehicle begins
to drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on, and it might even be noticed that the brake pedal
moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help the
driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps receiving
updates on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.Using ABS
Do not pump the brakes. Just hold the brake pedal down
rmly and let antilock work. A slight brake pedal pulsation
might be felt or some noise noticed, but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If the vehicle has ABS, it allows the driver to steer and
brake at the same time. However, if the vehicle does not
have ABS, the rst reaction — to hit the brake pedal hard
and hold it down — might be the wrong thing to do. The
wheels can stop rolling. Once they do, the vehicle cannot
respond to the driver’s steering. Momentum will carry
it in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing the driver was trying to avoid, or into traffic.
If the vehicle does not have ABS, use a “squeeze”
braking technique. This gives maximum braking while
maintaining steering control. Do this by pushing on
the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or feel
the wheels sliding, ease off the brake pedal. This helps
retain steering control. With ABS, it is different. See
Antilock Brake System (ABS) on page 4-4.
In many emergencies, steering can help more than
even the very best braking.
4-5

Electronic Stability Control (ESC)
The vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most driving
conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE ESC
message displays.
For more information, seeDriver Information Center
(DIC) on page 3-39andElectronic Stability Control
(ESC)/Traction Control System (TCS) Indicator/Warning
Light on page 3-31.
This light ashes on the
instrument panel cluster
when the ESC system is
on and activated.ESC activates when the computer senses a discrepancy
between the intended path and the direction the vehicle
is actually travelling. ESC selectively applies braking
pressure at any one of the vehicle’s brakes to help steer
the vehicle in the direction which you are steering.
When the system activates, an ESC ACTIVE message
displays on the Driver Information Center. SeeDIC
Warnings and Messages on page 3-42. This light also
ashes on the instrument panel cluster when the ESC
system is on and activated. A noise may be heard or a
vibration felt in the brake pedal. This is normal. Continue
to steer the vehicle in the intended direction.
When the light is on solid and the message(s), SERVICE
ESC, ESC OFF, or both display, the system will not assist
the driver in maintaining directional control of the vehicle.
Adjust your driving accordingly. SeeDIC Warnings and
Messages on page 3-42.
The ESC system is automatically enabled whenever
the vehicle is started. To assist the driver with vehicle
directional control, especially in slippery road conditions,
the system should always be left on. But, ESC can be
turned off if needed.
If cruise control is being used when ESC activates, the
cruise control automatically disengages. The cruise
control can be reengaged when road conditions allow.
SeeCruise Control on page 3-10.
4-6

The ESC/TCS button is
located on the instrument
panel.
The traction control system can be turned off or back on
by pressing the ESC/TCS button. To disable both traction
control and ESC, press and hold the button from ve to
ten seconds.
When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the
ESC/TCS light comes on to warn the driver that both
traction control and ESC are disabled.
It is recommended that the system remain on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” the vehicle to attempt to
free it. It may also be necessary to turn off the system
when driving in extreme off-road conditions where high
wheel spin is required. SeeIf Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 4-21.ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light comes
on to warn the driver that ESC is disabled and requires
service. If the problem does not clear after restarting the
vehicle, see your dealer/retailer for service. SeeDIC
Warnings and Messages on page 3-42for more
information.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Traction Control System (TCS)
The vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the front wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
by closing the throttle and managing engine spark to limit
wheel spin.
4-7

This light ashes while the
traction control system is
limiting wheel spin.
The system may be heard or felt while it is working.
This is normal and does not mean there is a problem
with the vehicle.
SeeElectronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-31
for more information.
If the vehicle is in cruise control while TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. SeeTurn Signal/Multifunction
Lever on page 3-7.
When this light is on and
either the SERVICE
TRACTION or TRACTION
OFF message is displayed,
the system will not limit
wheel spin.Adjust your driving accordingly. SeeDIC Warnings and
Messages on page 3-42for more information.
The Traction Control System comes on automatically
whenever the vehicle is started. It is recommended to
leave the system on for normal driving conditions, but it
may be necessary to turn the system off if the vehicle is
stuck in sand, mud, ice or snow, and you want to “rock”
your vehicle to attempt to free it. It may also be necessary
to turn off the system when driving in off-road conditions
where high wheel spin is required. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 4-21.
To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC displays the appropriate message as described
previously when the button is pressed.
4-8

Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that either of the front wheels are
spinning or beginning to lose traction while driving. For
more information on the LOW TRACTION message, see
Driver Information Center (DIC) on page 3-39.
Notice:If the wheel(s) of one axle are allowed
to spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, the
differential could be damaged. The repairs would not
be covered by the vehicle warranty. Reduce engine
power and do not spin the wheel(s) excessively while
these lights and this message are displayed.Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the drive wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
The traction control system may activate on dry or rough
roads or under conditions such as heavy acceleration
while turning or abrupt upshifts/downshifts of the
transmission. When this happens, a reduction in
acceleration may be noticed or a noise or vibration may
be heard. This is normal.
If the vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. The cruise control can
be re-engaged when road conditions allow. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-9

Enhanced Traction System (ETS)
The vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are spinning
or beginning to lose traction. When this happens, the
system reduces engine power and may also upshift the
transmission to limit wheel spin.
If the vehicle has ETS, there is not an ESC/TCS button
on the instrument panel. To turn the system off, shift
to L (Low) or R (Reverse). There is more information
about how to turn the system off later in this section.
The ETS indicator/warning light ashes and LOW
TRACTION appears on the Driver Information Center
(DIC) when the traction control system is actively limiting
wheel spin. The system may be heard or felt while it is
working, but this is normal. Slippery road conditions may
exist if this message is displayed, so adjust your driving
accordingly.
If the vehicle is in cruise control when the ETS begins
to limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. SeeCruise Control on page 3-10.The ETS indicator/warning light may come on for the
following reasons:
The indicator/warning light ashes while the traction
control system is limiting wheel spin.
If the system is turned off by moving the shift lever to
L (Low), the indicator/warning light comes on and
stays on. To turn the system back on, move the shift
lever back to a position other than L (Low). The
indicator/warning light should go off.
The indicator/warning light will come on when the
parking brake is set with the engine running, and it
will stay on if the parking brake does not release fully.
If the transmission shift lever is in any position other
than L (Low) and the indicator/warning light stays on
after the parking brake is fully released, there is a
problem with the system.
If the traction control system is affected by an engine
related problem, the system will turn off and the
indicator/warning light will come on.
4-10

If the ETS indicator/warning light comes on and stays on
for an extended period of time when the transmission
shift lever is in any position other than L (Low), the
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check the DIC messaging to determine whether it is
because of the driver turning off the system, or that the
system may not be working properly and the vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message will
be displayed.
SeeDIC Warnings and Messages on page 3-42for more
information on the messages associated with this light.
To limit wheel spin, especially in slippery road conditions,
ETS should always be left on. But the system can be
turned off if needed.
To turn the system off, shift to L (Low) or R (Reverse).When the system is turned off, the ETS indicator/warning
light will come on and stay on and the TRACTION OFF
message will be displayed when the gear shift is in
L (Low). The indicator/warning light and message
will not come on when the gear shift is in R (Reverse).
If the ETS is limiting wheel spin when the transmission is
shifted to L (Low) or R (Reverse) to turn the system off,
the indicator/warning light and TRACTION OFF will come
on in L (Low). But the system will not turn off right away.
It will wait until there is no longer a current need to limit
wheel spin. SeeDIC Warnings and Messages on
page 3-42for more information on the messages
associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdrive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-11

An emergency like this requires close attention and
a quick decision. If holding the steering wheel at the
recommended 9 and 3 o’clock positions, it can be turned
a full 180 degrees very quickly without removing either
hand. But you have to act fast, steer quickly, and just as
quickly straighten the wheel once you have avoided the
object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
Off-Road Recovery
The vehicle’s right wheels can drop off the edge of a
road onto the shoulder while driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that the vehicle straddles the edge of the pavement.
Turn the steering wheel 3 to 5 inches, 8 to 13 cm, (about
one-eighth turn) until the right front tire contacts the
pavement edge. Then turn the steering wheel to go
straight down the roadway.
