Check the washer fluid level often.
Cruise Control
A CAIJTION:
Cruise control can be dangerous where you
can’t drive safely at a steady speed.
So,
don’t use your cruise control on winding
roads or in heavy traffic.
slippery roads. On such roads, fast changes in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.
Cruise control can be dangerous on
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. (See “Traction Control System” in
the Index.) When road conditions
allow you to safely use it again, you may turn the cruise
control back
on.
With cruise control, you can maintain a speed of about 25
mph (40 km/h) or more without keeping your foot on the
accelerator.
This can help on long trips. Cruise control
does not work at speeds below
25 mph (40 M).
Cruise control shuts off when you apply your brakes.

Downloaded from www.Manualslib.com manuals search engine Setting Cruise Control
If you leave your cruise control switch on when
you’re not using cruise, you might hit a button
and
go into cruise when you don’t want to. You
could be startled and even lose control. Keep the
cruise control switch
off until you want to use it.
1. Move the cruise control switch to ON.
2. Accelerate to the speed you want.
3. Press the SET CRUISE button at the end of the lever
and release it. The CRUISE ENGAGED message
will display on the Driver Information Center (DIC).
4. Remove your foot from the accelerator pedal.
Resuming a Set Speed
Setting the cruise control at a desired speed and then
applying the brake will end the cruise function. Once you’re going about
25 mph (40 km/h) or
more,
you can move the cruise control switch
from ON to
R/A (Resume/Accelerate) for about half a second to
reset.
This returns you to your desired preset speed. Also
note that the Driver Information Center (DIC) will
display the CRUISE ENGAGED message again.
Remember, if you hold the switch at R/A longer than
half a second, the vehicle will accelerate until
you
release the switch or apply the brake. So unless you
want to go faster, don’t hold the switch at R/A.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher speed.
Push the button at the end of the lever and then
release the button and the accelerator pedal. You’ll
now cruise at the higher speed.
0 Move the cruise switch fiom ON to FUA. Hold it there
until you reach a desired
speed and then release the
switch.
(To increase your speed in very small amounts,
move the switch to R/A. Each time you do this, your
vehicle
will go about 1 mph (1.6 km/h) faster.)
The accelerate feature will only work after you have set the cruise control speed by pushing the SET
CRUISE button.

Downloaded from www.Manualslib.com manuals search engine Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:
Push in the button at the end of the lever until you
reach a desired lower speed, then release it.
A
CRUISE ENGAGED message will then display in
the Driver Information Center (DIC).
To slow down in very small amounts, push the
button for less than half a second. Each time you do
this, you’ll go
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot
off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills.
When going up steep hills, you may have to step on the
accelerator pedal
to maintain your speed. When going
downhill, you may have to brake or shift to. a lower gear to keep your speed down. Of course, applying the brakes
or downshifting into FIRST
(1) takes you out of cruise
control. Many drivers find this to be too much trouble
and don’t use cruise control on steep hills.
Ending Cruise Control
There are two ways to end cruise control:
Step lightly on the brake pedal.
Move the CRUISE switch to OFF.
Erasing Speed Memory
The cruise control set speed memory is erased when you
turn
off the cruise control or the ignition.

Downloaded from www.Manualslib.com manuals search engine Remember: Anti-lock doesn’t 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 won’t 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 anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may hear the
anti-lock pump or motor operate, and
1 1 the brake
pedal pulsate, but this is normal.
Traction Control System
Your vehicle has a traction control system 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 works the front brakes and
reduces engine power to limit wheel spin.
The TRACTION
ENGAGED message will display on
the Driver Information Center when the traction control
system is limiting wheel spin. See “Driver Information
Center Messages” in the Index. You may feel or hear the
system working, but this is normal. If
your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow
you to safely use it again, you may
reengage the cruise control. (See “Cruise Control” in
the Index.)
TRACTION
CONTROL
This warning light will come on to let you know if
there’s a problem with your
traction control system.
See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always leave the system
on. But you can turn the
traction control system
off if you ever need to. (You
should turn the system
off if your vehicle ever gets stuck
in sand, mud, ice or snow. See ‘.‘Rocking Your Vehicle”
in the Index.)

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one
of the identical size
and rating.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one that has the same amperage. Pick some feature
of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the engine
compartment fuse block and the rear compartment
fuse block.
