Tilt Wheel
If the vehicle has a tilt wheel it lets you adjust the
steering wheel before you drive. The steering
wheel can be raised to the highest level to give the
driver’s legs more room when you enter and exit
the vehicle.
The lever that allows
you to tilt the steering
wheel is located on
the left side of the
steering column.
To tilt the wheel, pull the lever down. Then move
the wheel to a comfortable position and pull
the lever up to lock the wheel in place.
Telescoping Column
If the vehicle has a telescoping column on the
steering wheel that adjusts the distance of
the steering wheel to the driver without moving
the driver’s seat.
The lever that makes
this adjustment is
located on the left side of
the steering column and
behind the tilt lever, if the
vehicle has this feature.
To adjust the steering wheel, pull the steering wheel
column lever down and push or pull the steering
wheel to a comfortable position. Then pull the lever
up to lock the wheel in place.
Do not drive the vehicle unless the telescoping
column is locked.

Turn and Lane-Change Signals
To signal a turn, move the lever up or down.
The lever returns to its original position when the
turn is completed.
An arrow on the
instrument panel
cluster will ash in the
direction of the turn or
lane change.
To signal a lane change, raise or lower the lever
until the arrow starts to ash. Hold it there until the
lane change is completed. The lever will return
to its original position when released.
Arrows that ash rapidly when signaling for a turn
or lane change, or that fail to work, may indicate
a burned-out signal bulb or fuse. Other drivers will
not see the signal. SeeFront Turn Signal and
Parking Lamps on page 397andTaillamps, Turn
Signal, Sidemarker, Stoplamps and Back-up
Lamps on page 398for turn signal bulb
replacement procedures. Also seeFuses and
Circuit Breakers on page 450for location of fuses.
A chime will sound if the turn signal is left on
for more than 3/4 mile (1.2 km).

Headlamp High/Low-Beam Changer
To change the headlamps from low beam to
high beam, push the turn signal/multifunction
lever away from you.
When the high beams
are on, a light on the
instrument panel cluster
also will be on if the
ignition is on.
To change the headlamps from high beam to low
beam, pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam
headlamps momentarily to signal a driver in
front of you that you want to pass.
To use it, pull the turn signal/multifunction lever
toward you until the high-beam headlamps
come on, then release the lever to turn them off.
Windshield Wipers
Be sure to clear ice and snow from the wiper
blades before using them. If they are frozen to the
windshield, gently loosen or thaw them. Damaged
wiper blades may not clear the windshield well,
making it harder to see and drive safely. If the
blades do become damaged, install new blades or
blade inserts. For more information, seeWindshield
Wiper Blade Replacement on page 401.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the
band to mist. Hold it there until the wipers
start. Then let go. The wipers will stop after
one wipe. If you want more wipe cycles, hold
the band on mist longer.
153

6(Delay):You can set the wiper speed for a long
or short delay between wiping cycles. This can
be very useful in light rain or snow. Turn the band
to choose the delay time. The closer to the top
of the lever, the shorter the delay.
6(Low Speed):For steady wiping at low
speed, turn the band away from you to the
rst solid band past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Windshield Washer
LQ(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top
of the multifunction lever. To spray washer uid on
the windshield, push the paddle. The wipers will
clear the window and then either stop or return to
your preset speed.
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
Cruise Control
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).
154

Page 155 of 512

{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not 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
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
If your vehicle is in cruise control when the
Traction Control System (TCS), if your vehicle
has this feature, begins to limit wheel spin,
the cruise control will automatically disengage.
SeeTraction Control System (TCS) on page 294.
When road conditions allow you to safely use
it again, the cruise control can be turned back on.The cruise control
buttons are located on
left side of the
steering wheel.
T(On/Off):Press this button to turn cruise
control on and off. The indicator will be lit
when cruise control is on.
+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET–:Press this button to set the speed or make
the vehicle decelerate.
[(Cancel):Press this button to cancel
cruise control.
155

Setting Cruise Control
Cruise control will not work if the parking brake is
set, or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel
cluster will come on after the cruise control
has been set to the desired speed. SeeInstrument
Panel Cluster on page 180.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Press the cruise control on/off button.
2. Get up to the speed you want.
3. Press and release the SET– button located on
the steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set the cruise control at a desired
speed and then you apply the brake. This shuts
off the cruise control, but it does not need to
be reset.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering
wheel. The vehicle will go back to your chosen
speed and stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using
cruise control:
Press and hold the +RES button on the
steering wheel until you reach your new
desired speed, then release it.
To increase vehicle speed in small increments,
press the +RES button.
156

Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until you reach the lower speed
you want, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time this is done, you will go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle
speed. When you take your foot off the pedal, the
vehicle will slow down to the cruise speed you
set earlier.
Using Cruise Control on Hills
How well the cruise control will work on hills
depends upon the vehicle 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 ends the cruise control. Many drivers
nd this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the
steering wheel.
Press theT(on/off) button on the
steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.

Daytime Running Lamps (DRL)/
Automatic Headlamp System
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. DRL lamps are required to function at
all times on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel
makes the DRL work, so be sure it is not covered.
The DRL system will make the low-beam
headlamps come on at reduced brightness when
the following conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness.
The turn signal, taillamps, sidemarker, and other
lamps will not be on. The instrument panel will not
be lit up either.
159

Page 160 of 512

When it is dark enough outside, the DRL will turn
off and the vehicle’s headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.
When it is bright enough outside, the headlamps
will go off and the DRL will come on.
To idle the vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the
headlamp position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
This feature is not available for vehicles rst sold
in Canada.
To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control
to the parking lamp position. The parking lamps
remain on and the headlamps turn off. The
fog lamps also go on if they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
If your vehicle has fog
lamps, the button is
located in the center of
the exterior lamps
control on the left side
of the steering column.
Press the fog lamps button to turn the lamps
on or off.
While the high-beam headlamps are on, the fog
lamps are off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left
on after the ignition has been turned to off, the
exterior lamps will turn off after about 10 minutes.
This protects the battery from being drained.
Use the exterior lamp control to turn the lamps
back on, if they are still needed.
