Personalization Setting
When you unlock the doors with
your remote, the driver's ID (Driver
1 or Driver 2) is detected, and the
climate control settings are turned to
the respective mode automatically
when the ignition is turned to the ON
(II) position.
Voice Control SystemOn models with navigation systemThe climate control system can also
be operated by voice control. See the
Navi section in your quick start guide
for an overview of this system, and
the navigation system manual for
complete details.Using Automatic Climate Control
The automatic climate control system
in your vehicle picks the proper
combination of air conditioning,
heating, and ventilation to maintain
the interior temperature you select.
The system also adjusts the fan
speed and airflow levels.
1. Press the Auto button on the front
control panel.
2. Set the desired temperature with the temperature control buttons.
You will see AUTO in the system's
display.
3. You can set the driver's side temperature, the passenger's side
temperature, and the temperature
of the rear passenger compartment
separately. The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your preference.
Temperature ControlThe driver's side temperature, the
passenger's side temperature and the
rear passenger compartment
temperature can be set separately.
Press the
▲button of the
appropriate temperature control to
increase the temperature of airflow.
Press the ▼button to decrease it.
Each set temperature is shown in the
display. The rear temperature is
shown in the display on the back of
the center console.

Rear ButtonWhen you press this button, the
indicator in the button comes on, and
the temperature of the rear
passenger compartment can be
adjusted separately with the
temperature control buttons on the
back of the center console. With the
indicator off, the temperature of the
rear passenger compartment is
synchronized to the driver's side set
temperature. You will see the AUTO
SYNC on the system display of the
rear control panel. Changing the
temperature of the rear passenger
compartment also makes the
indicator turn on, and takes the
system out of synchronized mode.
This causes the word SYNC in the
display to go out.To Turn Everything Off
If you press the OFF button, the
climate control system shuts off
completely.
●Keep the system completely off for
short periods only.●To keep stale air and mustiness
from collecting, you should have
the fan running at all times.
Semi-automatic Operation
You can manually select various
functions of the climate control
system when it is in fully automatic
mode. All other features remain
automatically controlled. Making any
manual selection causes the word
AUTO in the display to go out.
Fan Control
Press the
▲ button to increase the
fan speed and airflow. Press the
▼
button to decrease it.
Air Conditioning (A/C) ButtonThis button turns the air
conditioning on and off. You will see
A/C ON or A/C OFF in the display.
When you turn the A/C off, the
system cannot regulate the inside
temperature if you set the
temperature control below the
outside temperature.Recirculation ButtonWhen the indicator in the button is
on, air from the vehicle's interior is
sent throughout the system again.
When the indicator is off, air is
brought in from the outside of the
vehicle (fresh air mode).
The outside air intakes for the
climate control system are at the
base of the windshield. Keep this
area clear of leaves and other debris.
The system should be left in fresh air
mode under almost all conditions.
Keeping the system in recirculation
mode, particularly with the A/C off,
can cause the windows to fog up.

●Minimize the use of the air
conditioning system－The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.●Plan and combine trips －
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one.
Calculating Fuel EconomyMeasuring TechniquesDirect calculation is the
recommended source of information
about your actual fuel economy.
Using frequency of fill-ups or taking
fuel gauge readings are NOT
accurate measures of fuel economy.
Fuel economy may improve over the
first several thousand miles.
Checking Your Fuel Economy1)Fill the fuel tank until the nozzle automatically clicks off.
2)Reset trip counter to zero.
3)Record the total gallons (liters) needed to refill.
4)Follow one of the simple calculations above.

Driving on HillsWhen climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning off, reduce speed and, if
necessary, pull to the side of the road
to let the engine cool.
If the transmission shifts frequently
while going up a hill, shift to D
3.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shift down to D3.Do
not ‘‘ride ’’the brakes. Remember, it
takes longer to slow down and
stop when towing a trailer.
Handling Crosswinds and BuffetingCrosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
of the steering
wheel, then turn the wheel to the left
to get the trailer to move to the left.
Turn the wheel to the right to move
the trailer to the right.
ParkingFollow all normal precautions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer's
tires.
Retrieving a BoatIf the vehicle tires slip when
retrieving a boat from the water,
keep the transmission in the D
position and do not use the
sequential sport shift mode. This
prevents the transmission damage.
Towing Your Vehicle
Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page446.
