DIC Vehicle Personalization
Many features on your vehicle can be personalized.
This means that the operation of these features can
be set to operate differently depending on who is
driving the vehicle. See “Personal Options” later in
this section for the features that you can
personalize.
The personalization settings for other features are
automatically updated and saved as the driver
adjusts them. These include the following settings
and presets:
The radio presets, tone, volume, fade,
balance, equalization (EQ) settings and source
(radio or CD)
The last climate control setting
The Head-Up Display (HUD) position and
dimming level, if your vehicle has this feature
The instrument panel cluster dimming level and
last selected DIC display
Separate personalization settings are saved for two
different drivers. One of the keyless access
transmitters is assigned to driver 1. The other is
assigned to driver 2. The back of the keyless
access transmitters are labelled 1 or 2 to
correspond to each driver.The current driver’s preferences are recalled when
one of the following occurs:
The lock or unlock button on the keyless
access transmitter, labelled 1 or 2, is pressed.
The appropriate memory button, 1 or 2, located
on the driver’s door is pressed. SeeMemory
Seat, Mirrors and Steering Wheel on
page 10for more information.
A valid keyless access transmitter is detected
upon opening the driver’s door.
If more than one valid keyless access transmitter
is detected upon opening the driver’s door, the
driver preferences for the lowest driver number will
be recalled.
If a keyless access transmitter that is not
labelled 1 or 2 is used, the personalization system
will not recognize the transmitter. The Driver
Information Center (DIC) will not display a current
driver number and the features that are normally
programmed through the DIC will be set to
the default states. Also, if the OPTION button is
pressed, the DIC does not display the menus used
to set personalizations, but instead displays
OPTIONS UNAVAILABLE for a few seconds.

So here are some tips for passing:
Drive ahead. Look down the road, to the
sides, and to crossroads for situations
that might affect your passing patterns. If you
have any doubt whatsoever about making
a successful pass, wait for a better time.
Watch for traffic signs, pavement markings,
and lines. If you can see a sign up ahead
that might indicate a turn or an intersection,
delay your pass. A broken center line
usually indicates it is all right to pass, providing
the road ahead is clear. Never cross a solid
line on your side of the lane or a double
solid line, even if the road seems empty of
approaching traffic.
Do not get too close to the vehicle you want to
pass while you are awaiting an opportunity. For
one thing, following too closely reduces your
area of vision, especially if you are following a
larger vehicle. Also, you will not have adequate
space if the vehicle ahead suddenly slows or
stops. Keep back a reasonable distance.
When it looks like a chance to pass is coming
up, start to accelerate but stay in the right lane
and do not get too close. Time your move soyou will be increasing speed as the time comes
to move into the other lane. If the way is clear to
pass, you will have a running start that more
than makes up for the distance you would lose
by dropping back. And if something happens to
cause you to cancel your pass, you need only
slow down and drop back again and wait for
another opportunity.
If other vehicles are lined up to pass a slow
vehicle, wait your turn. But take care that
someone is not trying to pass you as you pull
out to pass the slow vehicle. Remember to
glance over your shoulder and check the
blind spot.
Check your vehicle’s mirrors, glance over your
shoulder, and start your left lane change signal
before moving out of the right lane to pass.
When you are far enough ahead of the passed
vehicle to see its front in your vehicle’s inside
mirror, activate the right lane change signal and
move back into the right lane. Remember that
an outside convex mirror makes the vehicle
you just passed seem farther away from you
than it really is.

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you
want the vehicle to go. If you start steering quickly
enough, your vehicle may straighten out. Always
be ready for a second skid if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle
control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road
to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Racing or Other Competitive Driving
See your warranty book before using your
vehicle for racing or other competitive driving.
Notice:If you use your vehicle for racing or
other competitive driving, the engine may
use more oil than it would with normal
use. Low oil levels can damage the engine.
For information on how to add oil, see
Engine Oil on page 333.
Z06 Only: Be sure to check the oil level often
during racing or other competitive driving
and keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick.
Except Z06: Be sure to check the oil level
often during racing or other competitive driving
and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
After the competitive driving, remove excess
oil so that the level on the dipstick is not
above the upper mark that shows the proper
operating range.

Vehicles with the Z51 performance package
have greaseable outer ends on both of the rear
toe-links. Under normal use, lubrication should
be performed as described in the maintenance
schedule. SeeScheduled Maintenance on
page 433andRecommended Fluids and
Lubricants on page 443. If you use the vehicle
for racing, lubrication should be performed at the
end of each racing day. See your dealer/retailer
for lubrication and make sure any needed
repairs are made at once. Proper procedures for
performing these services can be found in the
service manual. SeeService Publications
Ordering Information on page 468.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce
the glare from headlamps behind you.
Since you cannot see as well, slow down
and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.

The most important advice on freeway driving is:
Keep up with traffic and keep to the right.
Drive at the same speed most of the other drivers
are driving. Too-fast or too-slow driving breaks
a smooth traffic ow. Treat the left lane on
a freeway as a passing lane.
At the entrance, there is usually a ramp that leads
to the freeway. If you have a clear view of the
freeway as you drive along the entrance ramp, you
should begin to check traffic. Try to determine
where you expect to blend with the ow. Try to
merge into the gap at close to the prevailing speed.
Switch on your turn signal, check your mirrors, and
glance over your shoulder as often as necessary.
Try to blend smoothly with the traffic ow.
Once you are on the freeway, adjust your speed
to the posted limit or to the prevailing rate if it
is slower. Stay in the right lane unless you want
to pass.Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.

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 rearview 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.
