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.
Press the button at the end of the lever, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.

Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release the switch. To increase your speed in
very small amounts, move the switch briefly to R/A.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise Control

Press in the SET button at the end of the lever until
you reach the lower speed you want, then release it.

To slow down in very small amounts, press the SET
button briefly. Each time you do this, you'll go about
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 want 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 brake
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 turn off the cruise control:

Step lightly on the brake pedal or push the clutch
pedal, if you have a manual transmission.

Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later
in this section for more information
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on, the driver's
door is opened and your ignition is in OFF, LOCK or
ACCESSORY. To turn the chime off, turn the knob all
the way to the left or turn the instrument panel dimmer
down to the fully dimmed position. In the automatic
mode, the headlamps turn off once the ignition key is
in OFF.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially helpful
in the short periods after dawn and before sunset.
Fully functional daytime running lights are required
on all vehicles first sold in Canada.
The DRL system will make your headlamps come on at
reduced brightness when the following conditions are met:

The ignition is on,

the headlamp switch is in automatic headlamp mode,

the sensor detects daytime light,

an automatic transmission is not in PARK (P), and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.

The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.
To idle an automatic transmission vehicle with the
DRL off, put the transmission in PARK (P). To idle a
manual transmission vehicle with the DRL off, set the
parking brake. The DRL will stay off until you shift out
of PARK (P) or release the parking brake.
The following does not apply to vehicles sold in Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following the steps below:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you that the
system is off. The system will revert back to the
automatic on mode when the ignition is turned to
OFF and then to RUN again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(a chime will sound), or turn the ignition to OFF
and then to RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps must be on for your
fog lamps to work.
The fog lamp switch is located on the instrument panel
under the lamp switch. Press the switch to turn the
fog lamps on. Press the switch again to turn them off.
A light will glow in the switch when the fog lamps are on.
Fog lamps will go off whenever your high
-beam
headlamps come on. When the high beams go off,
the fog lamps will come on again.

You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Shift Light
You have the shift light
on the instrument panel
cluster if you have a
manual transmission.
Shifting when the indicator light is on will help you get
the best fuel economy. See ªShift Lightº in the Index.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on if your parking brake doesn't release fully.
If it stays on after your parking brake is fully released,
it means you have a brake problem.
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.

This light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then,
have it fixed so it will be ready to warn you if there's
a problem.
If the light comes on while you are driving, 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 floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will
come on when you start
your engine and may stay
on for several seconds.
That's normal.
If the light stays on, or comes on when you're driving,
your vehicle needs service. If the regular brake system
warning light isn't on, you still have brakes, but you
don't have anti
-lock brakes. If the regular brake system
warning light is also on, you don't have anti
-lock
brakes and there's a problem with your regular brakes.
See ªBrake System Warning Lightº earlier in
this section.
The anti
-lock brake system warning light should
come on briefly when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so it will
be ready to warn you if there is a problem.

4-3 Driving Environment
You can also help avoid a rollover or other type of crash
by being prepared for driving in inclement weather, at
night, or during other times where visibility or traction
may be limited (such as on curves, slippery roads or
hilly terrain). Unfamiliar surroundings can also have
hidden hazards. To help you learn more about driving
in different conditions, this section contains information
about city, freeway, and off
-road driving, as well as
other hints for driving in various weather conditions.
Vehicle Design
According to the U.S. Department of Transportation,
utility vehicles have a significantly higher rollover rate
than other types of vehicles. Utility vehicles do have
a higher ground clearance and a narrower track or
shorter wheelbase than passenger cars to make them
more capable for off
-road driving. Specific design
characteristics like these give the driver a better view of
the road, but also give utility vehicles a higher center of
gravity than other types of vehicles. This means that you
shouldn't expect a utility vehicle to handle the same way
a vehicle with a lower center of gravity, like a car, would
in similar situations. But driver behavior factors are far more often the cause
of a utility vehicle rollover than are environmental or
vehicle factors. Safe driver behavior and understanding
the environment in which you'll be driving can help
avoid a rollover crash in any type of vehicle, including
utility vehicles.
Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
vehicle: Buckle up. See ªSafety Beltsº in the Index.
Defensive driving really means ªbe ready for anything.º
On city streets, rural roads or freeways, it means
ªalways expect the unexpected.º
Assume that pedestrians or other drivers are going to
be careless and make mistakes. Anticipate what they
might do. Be ready for their mistakes.
Rear
-end collisions are about the most preventable
of accidents. Yet they are common. Allow enough
following distance. It's the best defensive driving
maneuver, in both city and rural driving. You never
know when the vehicle in front of you is going to brake
or turn suddenly.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you're driving on snow or ice, it's
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's perception time. Then you have to bring up
your foot and do it. That's reaction time.
Average reaction time is about 3/4 of a second.
But that's 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 3/4 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 your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it's pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.
