Using Cruise Control on Hills
How well your cruise control works on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you
might have to step on the accelerator pedal to
maintain your speed. When going downhill,
you might have to brake or shift to a lower gear to
keep your vehicle’s speed down. Of course,
applying the brake turns off the cruise control.
Many drivers nd this to be too much trouble and
do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal
Move the cruise control switch to off
Erasing Speed Memory
Turning off the cruise control or the ignition, will
erase your cruise control set speed memory.

When following a vehicle and entering a curve,
Adaptive Cruise Control could lose track of
the vehicle in your lane and accelerate your
vehicle. When this happens, the vehicle ahead
symbol will not appear on the HUD.Adaptive Cruise Control may detect a vehicle that
is not in your lane and apply the brakes.
Adaptive Cruise Control may, occasionally,
provide a driver alert and/or braking that you
consider unnecessary. It could respond to signs,
guardrails and other stationary objects when
entering or exiting a curve. This is normal
operation. Your vehicle does not need service.

Using Adaptive Cruise Control on Hills
How well Adaptive Cruise Control will work on hills
depends on your speed, vehicle load, traffic
conditions and the steepness of the hills. It may
not detect a vehicle in your lane while driving
on hills. When going up steep hills, you may want
to use the accelerator pedal to maintain your
speed. When going downhill, you may have to
brake to keep your speed down. Applying
the brake disengages the system. You may
choose not to use Adaptive Cruise Control on
steep hills.
Disengaging Adaptive Cruise Control
To disengage the system, apply the brake pedal
or move the Adaptive Cruise Control switch to
off. Adaptive Cruise Control information will
not appear on the HUD when the system is not
engaged.
Erasing Set Speed Memory
When you turn the Adaptive Cruise Control switch
or the ignition off, the set speed memory is
erased.
Other Messages
There are three messages that may appear in the
Driver Information Center (DIC). They are
SERVICE RADAR CRUISE, CRUISE NOT READY
and CLEAN RADAR CRUISE. These messages
will only appear to indicate a problem if Adaptive
Cruise Control is active. SeeDIC Warnings
and Messages on page 206for more information.
You may also see CRUISE SPEED LIMITED
displayed in the HUD. SeeHead-Up Display
(HUD) on page 171for more information.

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel cluster, which shows a deployed
airbag symbol. The system checks the airbag’s
electrical system for malfunctions. The light
tells you if there is an electrical problem. The
system check includes the airbag modules,
the wiring and the diagnostic module. For more
information on the airbag system, seeAirbag
System on page 44.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the vehicle on. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

If the word OFF or the off symbol is lit on the
passenger airbag status indicator, it means that
the passenger sensing system has turned off
the passenger’s airbags. SeePassenger Sensing
System on page 53for more on this, including
important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the airbag off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the airbag. SeeAirbag
Readiness Light on page 188.
Charging System Light
When you turn the
engine on, this light will
come on briey to
show that the generator
and battery charging
systems are working
properly.
If this light stays on, your vehicle needs service.
You should take your vehicle to the dealer at once.
To save your battery until you get there, turn off
all accessories. SeeDIC Controls and Displays on
page 204for more information.

If the light comes on while you are driving and you
have a LOW BRAKE FLUID message showing
on the DIC, pull off the road and stop carefully.
You may notice that the pedal is harder to
push. Or, the pedal may go closer to the oor. It
may take longer to stop. If the light is still on, have
the vehicle towed for service. SeeTowing Your
Vehicle on page 359.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light

That is normal.
If the light stays on, turn the ignition off or if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the
engine again to reset the system. If the light still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. See “Service ABS” underDIC
Warnings and Messages on page 206.

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the sameTire Performance Criteria (TPC) can affect your
vehicle’s emission controls and may cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This may also result
in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 363.
This light should come on briey, as a check to
show you it is working, as you start the engine. If
the light does not come on, have it repaired.
This light will also come on during a malfunction in
one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
