Tilt Wheel
The steering wheel should be adjusted before
you drive.
The tilt lever is located
to the left of the steering
column, under the
turn signal lever.
It can be raised to the highest level to give
your legs more room when you enter and exit
the vehicle.
To tilt the wheel, hold the steering wheel and pull
the lever toward you. Move the steering wheel
to a comfortable level, then 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
23Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
NWindshield Wipers
JWindshield Washer
ICruise Control
171

N(Windshield Wipers):Turn the band to
control the windshield wipers.
The wiper speed can be set for a long or short
delay between wipes. 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.
For steady wiping at low speed, turn the band
away from you to the rst solid band past the delay
settings. For high-speed wiping, turn the band
further, to the second solid band past the
delay settings. To stop the wipers, move the
band to off.
Be sure to clear ice and snow from the wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If the
blades do become worn or damaged, get new
blades or blade inserts.Windshield Washer
L(Windshield Washer):To spray washer uid
on the windshield, press the windshield washer
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.
Rear Window Wiper/Washer
{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.
174

The rear window/washer
control is located to
the right of the
steering wheel on the
instrument panel.
To turn the rear wiper on, turn the control to
either 1, 2, or 3. For delayed wiping, turn the
control to 1 or 2. For steady wiping, turn the control
to 3. To turn the wiper off, turn the control to 0.
To wash the rear window, press the washer
symbol located in the center of the control.
The rear window washer uses the uid from the
same reservoir as the windshield washer.
However, the rear window washer runs out of uid
before the windshield washer. If you can wash
your windshield but not your rear window, check
the uid level.Headlamp Washer
Your vehicle may have
a headlamp washer
system. The button to
operate this feature
is located on the
instrument panel and
functions separately
from your other
washer systems.
To wash your headlamps, press the headlamp
washer button briey and release to activate
the system.

If this message appears on the DIC, stop as soon
as you can. Have the tire pressures checked
and set to those shown on the Tire Loading
Information Label. SeeTires on page 439,Loading
Your Vehicle on page 349, andInation - Tire
Pressure on page 447. If the tire pressure is low,
the low tire pressure warning light comes on.
SeeTire Pressure Light on page 209.
CHECK WASHER FLUID
This message displays if the washer uid level is
low. Adding washer uid to the windshield
washer uid reservoir clears this message. See
Windshield Washer Fluid on page 418. This
message clears itself after 10 seconds, or you can
press any of the DIC buttons, or the trip stem,
to acknowledge this message and clear it from the
DIC display.
CURB VIEW ACTIVATED
This message displays when the passenger
outside rearview mirror moves into the curb view
position. SeeOutside Curb View Assist Mirror
on page 144for more information.
DRIVER DOOR AJAR
This message displays and a chime sounds if the
driver’s door is not fully closed. Stop and turn
off the vehicle, check the door for obstructions, and
close the door again. Check to see if the
message still appears on the DIC. Press any of
the DIC buttons, or the trip stem, to acknowledge
this message and clear it from the DIC display.

The heavier the rain, the harder it is to see. Even if
your windshield wiper blades are in good shape, a
heavy rain can make it harder to see road signs and
traffic signals, pavement markings, the edge of the
road, and even people walking.
It is wise to keep your wiping equipment in good
shape and keep your windshield washer uid
reservoir lled with washer uid. Replace your
windshield wiper inserts when they show signs of
streaking or missing areas on the windshield, or
when strips of rubber start to separate from the
inserts.
{CAUTION:
Wet brakes can cause accidents. They may
not work as well in a quick stop and may
cause pulling to one side. You could lose
control of the vehicle.
After driving through a large puddle of
water or a car wash, apply your brake pedal
lightly until your brakes work normally.Driving too fast through large water puddles or
even going through some car washes can cause
problems, too. The water may affect your brakes.
Try to avoid puddles. But if you cannot, try to slow
down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can
build up under your tires that they can actually ride
on the water. This can happen if the road is wet
enough and you are going fast enough. When your
vehicle is hydroplaning, it has little or no contact
with the road.
Hydroplaning does not happen often. But it can
if your tires do not have much tread or if the
pressure in one or more is low. It can happen if a
lot of water is standing on the road. If you can
see reections from trees, telephone poles,
or other vehicles, and raindrops dimple the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just is not a hard and fast rule about
hydroplaning. The best advice is to slow down
when it is raining.

Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency
supplies in your vehicle.
Also seeTires on page 439.Include an ice scraper, a small brush or broom,
a supply of windshield washer uid, a rag,
some winter outer clothing, a small shovel,
a ashlight, a red cloth, and reective warning
triangles. And, if you will be driving under severe
conditions, include a small bag of sand, a
piece of old carpet, or a couple of burlap bags to
help provide traction. Be sure you properly
secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the tires
and the road, you can have a very slippery
situation. You will have a lot less traction, or grip,
and will need to be very careful.
