Horn
To sound the horn, press the center pad on the
steering wheel.
Tilt Wheel
If your vehicle is equipped with a tilt wheel, it will allow
you to adjust the steering wheel before you drive.
You can raise it to the highest level to give your legs
more room when you exit and enter your vehicle.
The tilt steering wheel
lever is located on the
lower left side of the
column.
To tilt the wheel, hold the steering wheel and pull the
lever. Then move the steering wheel to a comfortable
position and release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
•GTurn and Lane Change Signals
•3Headlamp High/Low Beam Changer
•Flash-to-Pass Feature
•NWindshield Wipers
•LWindshield Washer
•JCruise Control (If Equipped)

Cruise Control
9
:Off
R:On
S:Resume/Accelerate
T:Set
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 really help on long trips. Cruise control does
not work at speeds below about 25 mph (40 km/h).
If you apply your brakes, or press the clutch pedal
(if equipped), the cruise control will disengage.
{CAUTION:
•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.
•Cruise control can be dangerous on
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.

Setting Cruise Control
{CAUTION:
If you leave your cruise control 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
cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The cruise light on the
instrument panel will
illuminate when the cruise
control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake or press the clutch
pedal (if equipped). This, of course, disengages the
cruise control. But you don’t need to reset it.
Once you’re going about 25 mph (40 km/h) or more,
you can move the cruise control switch from on to
resume/accelerate briefly.
You’ll go right back up to your chosen speed and
stay there.
If you hold the switch at resume/accelerate briefly, the
vehicle will keep going faster until you release the switch
or apply the brake. So unless you want to go faster,
don’t hold the switch at resume/accelerate.

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 set 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
resume/accelerate. 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 resume/accelerate briefly.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
•
Press and hold 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
driversfind this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
•Step lightly on the brake pedal.
•Step lightly on the clutch pedal (if equipped).
•Move the cruise control switch to off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Oil Pressure Gage
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in kPa
(kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused
by a dangerously low oil level or some other problem
causing low oil pressure. Check your oil as soon
as possible. SeeDIC Warnings and Messages on
page 3-51andEngine Oil on page 5-13.
{CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catchesre. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Cruise Control Light
The cruise light comes on
whenever you set your
cruise control. See“Cruise
