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.
To Get Out of Cruise Control
There are two ways to turn off the Cruise Control:
0 Step lightly on
the brake pedal or
push the clutch
pedal, if you have
a manual
transmission
OR;
0 move the Cruise switch to
OFF.
To Erase 5peed Memory
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)
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 Running \
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 beams will change 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.

just to
let you know they're working. If you are familiar with this section, you
should not be alarmed when this happens.
Gages can indicate when there may be or is a problem with one of your
vehicle's functions. Often gages and warning lights work together
to let you

a problem with your vehicle.
When one
of the warning lights comes on and stays on when you are

Listed are four situations you may experience with your fuel gage:
0 At the gas station, the fuel pump shuts off before the gage reads full.
0 It takes a little more or less fuel to fill up than the fuel gage indicated.
For example, the gage may have indicated the tank was half full, but it
actually took a little more or less than half the tank’s capacity to fill the
tank.
0 The gage moves a little when you turn a corner or speed up.
0 The gage doesn’t go back to empty when you turn off the ignition.
None of these indicate a problem
with the fuel gage.
For information
on how to fill your fuel tank, see “Fuel - Filling Your
Tank”
in the Index.
For your fuel tank capacity, see “Fuel -Tank Capacity”
in the Index.
This gage shows the engine coolant temperature. If the gage pointer moves
into the red area, about
260°F (145°C) or more, your engine is too hot! It
means that your engine coolant has overheated.
If you have been operating
your vehicle under normal operating conditions, you should pull
off the
road, stop your vehicle, and turn off the engine as soon as possible.
Hot Coolant Can Burn You Badly!‘
