If your vehicle has four-wheel drive, you can send your engine’\
s driving power
to all four wheels for extra traction. To get the most satisfaction out of
four-wheel drive, you must be familiar with it’s operation. \

follows before using four-wheel drive. You should use
2H for most normal
driving conditions.
Rear-wheel antilock brakes
do not work when you shift into four-wheel drive.
Your regular brakes will still work. When you shift back into two-w\
heel drive,
your rear-wheel antilock brakes will take over again.
I NOTICE
Driving in the 4H or 4L positions for a long time on dry or wet pavement
could shorten the life
of your vehicle’s drivetrain.

Cruise Control (Option)
K2247
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 re\
ally help on
long trips. Cruise Control does not work at speeds below about 25 mph
(40 km/h).
When you apply your brakes, or push the clutch pedal, if you \
have
a manual
transmission, the Cruise Control shuts
off.

To Resume a Set Speed
Suppose you set your Cruise Control at a desired speed and th\
en you apply
the brake. This, of course, shuts off the Cruise Control. But you don’t need
to reset it. Once you’re going about
25 mph (40 kmlh) or more, you can
move the Cruise switch
from ON to RIA for about half a second.
I
K224
You’ll go right back up to your chosen speed and stay ther\
e.
I
r 4 If you hold the switch at R/A longer than half a second, the vehicle
will keep going faster until you release the switch or apply \
the brake.
You could be startled and even lose control.
So unless you want to
1 go faster, don’t hold the switch at R/A.

To Reduce Speed While Using Cruise Control
1
K2260
1. Push in the button at the end of the lever until you reach the lower
speed you want, then release it.
2. To slow down in very small amounts, push the button for less than a
half 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 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.
When you turn
off the Cruise Control or the ignition, your Cruise Control set
speed memory
is erased.

Daytime Running Lights (DRL) Indicator Light (Canada Only)
K2318
If your vehicle was first sold, when new, in Canada, you will have this light on
the instrument panel. It goes on whenever the Daytime Running \
Lights are on.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that “Daytime Run\
ning
Lights” (DRL) are a useful feature, in that
DRL can make your vehicle more
visible to pedestrians and other drivers during daylight hours. DRL are
required on new vehicles sold in Canada.
The high beam headlights will come on at reduced brightness in daylight
when:
The ignition is on
The headlight switch is off, and
The parking brake is released
When you turn on your headlights, the DRL
will switch off and the exterior
lights will come on. When you turn
off the headlights, the exterior lights will
go out and the high beam lights will switch to the reduced brightness
of DRL
again. The DRL indicator light on the instrument panel will go\
on whenever
the DRL are on. This light means that only the DRL are on. When you turn
on your exterior lights, this light will go out.
Of course, you may still turn on
the headlights any time you need to.
To idle your vehicle with the DRL off, set the parking brake. The DRL will
stay
off until you release the parking brake.
