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 WA. 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 to R/A for less
than a
1/2 second. Each time you do this, your
vehicle will go about
1 mph (1.6 kmh) faster.)
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:
Press in the 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
button for less than- a
1/2 second. Each time you do
this, you’ll go 1 mph (1.6 kmh) 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.
If the steepness
of the
hill causes the vehicle speed to drop more than
15 mph (24 kmh) below the set speed, your cruise control
will automatically disengage. 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
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.

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.
The
DRL system will make your headlamps come on at
a reduced brightness when:
the ignition is on,
the headlamp switch is off, 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.
Your instrument panel won’t be lit up either. When
it begins to get dark, your DRL indicator light
is a
reminder to turn your headlamp switch on. The
other lamps that
come on with your headlamps will
also come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps
will change to
the reduced brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake.
The DRL 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.
