Passenger Airbag Status Indicator
Your rearview mirror has a passenger airbag
status indicator.When the vehicle is started, the passenger airbag
status indicator will light ON and OFF, or the
symbol for on and off, for several seconds as a
system check. Then, after several more seconds,
the status indicator will light either ON or OFF,
or either the on or off symbol, to let you know
the status of the passenger’s frontal airbag
and side impact airbag (if equipped).
Your vehicle has a label on the sun visor that
says, “Never put a rear-facing child seat in
the front.” This is because the risk to the
rear-facing child is so great if the airbag deploys.

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.

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.
