WARNING
● The air conditioner cooling function op-
erates only when the engine is running.
●
Do not leave children or adults who would
normally require the assistance of others
alone in your vehicle. Pets should also not
be left alone. They could accidentally in-
jure themselves or others through inad-
vertent operation of the vehicle. Also, on
hot, sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly fatal
injuries to people or animals.
● Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
NOTE: ● Odors from inside and outside the vehicle
can build up in the air conditioner unit. Odor
can enter the passenger compartment
through the vents.
● When parking, set the heater and air condi-
tioner controls to turn off air recirculation to
allow fresh air into the passenger compart-
ment. This should help reduce odors inside
the vehicle.LHA2505

Operating tips
●Keep the windows and moonroof closed
while the air conditioner is in operation.
● After parking in the sun, drive for 2 or 3 min-
utes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
● The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
● A visible mist may be seen coming from the
ventilators in hot, humid conditions as the air
is cooled rapidly. This does not indicate a
malfunction.
● If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

Follow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
● Avoid rapid starts and stops
● Use smooth, gentle accelerator and
brake application whenever possible
● Maintain constant speed while commut-
ing and coast whenever possible
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops
● Maintaining a steady speed can minimize
red light stops and improve fuel efficiency
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load ●
Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag
● Recirculating the cool air in the cabin
when the A/C is on reduces cooling load
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes
● Select a gear range suitable to road con-
ditions
5. Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains 6.
Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time
7. Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy
● Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driv-
ing
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling
