Driving and Operating 9-57
Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
9(Off): Turns the cruise control
system off.
R (On): Turns the cruise control the
system on.
S(Resume/Accelerate): Makes
the vehicle accelerate or resume to
a previously set speed.
rT (Set): Press this button to set
the speed.
Cruise control will not work if the
parking brake is set, or if the master
cylinder brake fluid level is low.
If the brakes are applied, the cruise
control shuts off.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
(Continued)
WARNING (Continued)
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.
The cruise control disengages, if the
vehicle has the Traction Control
System (TCS) and it begins to limit
wheel spin. See Traction Control
System (TCS)
on page 9‑52.
When road conditions allow the
cruise control to be safely used
again, it can be turned back on.

9-58 Driving and Operating
Setting Cruise Control
{WARNING
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. Move the cruise control switch to on.
2. Get up to the speed desired. 3. Press
Tat the end of the lever
and release it.
4. Take your foot off the accelerator pedal.
The cruise symbol on the instrument
panel comes on when the cruise
control is engaged. Resuming a Set Speed
Suppose the cruise control is set at
a desired speed and then you apply
the brake or step on the clutch. This
disengages the cruise control. But it
does not need to be reset.
Once the vehicle is going about
40 km/h (25 mph) or more, move
the cruise control switch briefly
from
RtoS.
The vehicle goes back to the
chosen speed and stays there.
If the switch is held at resume/
accelerate the vehicle keeps going
faster until the switch is released or
the brake is applied. Do not hold the
switch at resume/accelerate, unless
you want the vehicle to go faster.

Driving and Operating 9-59
Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed:
.Use the accelerator pedal
to get to the higher speed.
Press
Tat the end of the
lever, then release the button
and the accelerator pedal. The
vehicle will now cruise at the
higher speed. If the accelerator
pedal is held longer than
60 seconds, cruise control will
turn off.
.Move the cruise switch
from
RtoS. Hold it there until
the desired speed is reached,
and then release the switch.
To increase the vehicle speed in
small amounts, move the switch
briefly to resume/accelerate.
Each time this is done, the
vehicle goes about 1.6 km/h
(1 mph) faster. Reducing Speed While Using
Cruise Control
.Press and holdTuntil the
desired lower speed is reached,
then release it.
.To slow down in very small
amounts, briefly press
T. Each
time this is done, the vehicle
goes about 1.6 km/h (1 mph)
slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the cruise
control speed set earlier. Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle's
speed, load, and the steepness of
the hills. When going up steep hills,
the accelerator pedal might have to
be used to maintain the vehicle
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep the vehicle
speed down. When the brake is
applied the cruise control will
turn off.

9-60 Driving and Operating
Ending Cruise Control
To turn off the cruise control, do
one of the following:
.Step lightly on the brake pedal.
.Move the cruise control switch
to
9.
.Lightly tap or press the clutch,
if the vehicle has a manual
transmission.
Erasing Speed Memory
The cruise control set speed
memory is erased, when the cruise
control or the ignition is turned off.
Object Detection
Systems
Rear Vision
Camera (RVC)
Vehicles with the rear vision camera
system are designed to help the
driver while the vehicle is backing
up. The area behind the vehicle is
displayed on the screen in the
inside rear view mirror. Read this
entire section before using the
camera system.
When the key is in the ON/RUN
position and the driver shifts the
vehicle into R (Reverse), the video
image appears from inside the rear
view mirror. Once the vehicle is
shifted out of R (Reverse), the
image disappears. The display may have a guideline
overlay that can help the driver align
the vehicle when backing into a
parking spot.
Turning the Rear Vision Camera
System On or Off
To turn off the rear vision camera
system, press and hold
z, located
on the inside rearview mirror, until
the left indicator light turns off. The
rear camera vision display is now
disabled.
To turn the rear vision camera
system on again, press and
hold
zuntil the left indicator light
illuminates. The rear vision camera
system display is now enabled and
the display will appear in the mirror
normally.

Driving and Operating 9-61
{WARNING
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
.Detect objects that are
outside the camera's field 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 RVC 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. (Continued)
WARNING (Continued)
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 and around the
vehicle. Rear Vision Camera Location

The image on the screen is
provided by the camera located on
the rear bumper.
The image from the camera that
appears on the screen appears
farther than the actual distance.
The area displayed by the camera
is limited. The camera does not
display objects which are close to
either corner of the bumper or under
the bumper. On the H3, the spare
tire and carrier extends rearward of
the rear bumper. The area displayed
on the screen may vary according to
vehicle orientation or road
conditions.
The following illustration shows
the field of view that the camera
provides.
H3 Field of ViewNotice:
The spare tire extends
farther away from rear of the
vehicle than the trailer hitch
shown on rear vision camera
display. The spare tire could hit
an object even though there
appears to be enough distance on
the display between the trailer
hitch and objects behind you
causing vehicle or property
damage. Do not use this system
to judge the distance between the
spare tire and objects
behind you.

To Work Properly
The rear vision camera system may
not work properly or display a clear
image:
.In the dark.
.When the sun or the beam of
headlamps is shining directly
into the camera lens.
.If ice, snow, mud, or anything
else builds up on the camera
lens. Clean the lens, rinse it with
water, and wipe it with a soft
cloth.
.If the back of the vehicle is in
an accident, the position and
mounting angle of the camera
may change or the camera may
be affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer.
.If there are extreme
temperatures or extreme
temperature changes.
The rear vision camera system
display in the rearview mirror may
turn off or not appear as expected
due to a loss of video signal, or no

Fuel
Use of the recommended fuel is
an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
The 8th digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.The VIN is at the top left of the
instrument panel. See
Vehicle
Identification Number (VIN)
on
page 12‑1.
If the vehicle has the 5.3L V8 engine
(VIN Code P), you can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol)
on
page 9‑66. In all other engines, use
only regular unleaded gasoline.
Recommended Fuel
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.
