Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger side mirror is convex. A convex mirror’s
surface is curved so more can be seen from the
driver seat. It also makes things, like other vehicles,
look farther away than they really are.
Object Detection Systems
Rear Vision Camera
Your vehicle may be equipped with a rear vision camera
system. Read this entire section before using the
camera system.
The rear vision camera system is designed to help the
driver when backing up by displaying a view of the area
behind the vehicle. When the driver shifts the vehicle into
REVERSE (R), the video screen will automatically slide
out from the rear view mirror. Once the driver shifts out of
REVERSE (R), the video screen will slide back into the
rear view mirror after a delay.
The display has a guideline overlay that can help the
driver align the vehicle when backing into a parking spot.
To turn off the rear vision camera system, do the
following:
1. Place the vehicle shift lever in PARK (P).
2. Turn the ignition key to the ACCESSORY position.
3. Press the right mirror button briey; the right
green light indicator will turn off. The rear camera
vision display is now disabled.
2-44

To turn on the rear camera vision feature again, press
the right mirror button briey. The green light indicator
will illuminate. The rear camera vision system is
now enabled and the display will slide out from the
mirror normally.
To manually slide out the rear camera screen for
cleaning, do the following:
1. Place the vehicle shift lever in PARK (P).
2. Turn the ignition key to the ACCESSORY or
RUN position.
3. Press and hold the right mirror button for
ve seconds. The display will slide out from
the mirror for 30 seconds; the right green LED
indicator will remain illuminated. The camera
screen will not be on when it slides out of
the mirror.
4. If additional time is required for cleaning,
repeat step 3.
To resume normal operation, press the right button
momentarily while the rear camera screen is out or wait
30 seconds for screen to slide back into the mirror.
For more information on the automatic dimming,
compass, and temperature features of the mirror, see
Automatic Dimming Rearview Mirror with Compass
and Temperature Display on page 2-41.
{CAUTION:
The Rear Vision Camera (RVC) system does
not replace driver vision. RVC does not:
Detect objects that are outside the
camera’s eld of view, below the bumper,
or underneath the vehicle.
Detect children, pedestrians, bicyclists,
or pets.
Do not back the vehicle by only looking at the
rear vision camera screen, or use the screen
during longer, higher speed backing maneuvers
or where there could be cross-traffic. Your
judged distances using the screen will differ
from actual distances.
So if you do not use proper care before backing
up, you could hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in vehicle damage,
injury, or death. Even though the vehicle has
the RVC system, always check carefully before
backing up by checking behind your vehicle.

Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired — by
alcohol or drugs, with night vision problems, or by
fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by adjusting the inside
rearview mirror.
Slow down and keep more space between you and
other vehicles because your headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into approaching headlamps.
Keep the windshield and all glass on your vehicle
clean — inside and out.
Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel? Have up-to-date
maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a
safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
