WARNING

Failure to follow the warnings and in-
structions for proper use of the I-FCW
system could result in serious injury or
death.

∙ The I-FCW system can help warn the

driver before a collision occurs but will
not avoid a collision. It is the driver’s
responsibility

to

stay

alert,

drive

safely and be in control of the vehicle
at all times.

The I-FCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle
ahead in the same lane.

The I-FCW system uses a radar sensor

䊊

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 com-

muting and coast whenever pos-
sible.

2. Maintain Constant Speed

∙ Look ahead to try and anticipate and

minimize stops.

∙ Synchronizing your speed with traffic

lights allows you to reduce your num-
ber of stops.

∙ Maintaining a steady speed can mini-

mize 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

exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.

∙ Maintaining a safe following distance

behind other vehicles reduces un-
necessary braking.

∙ Safely monitoring traffic to anticipate

changes in speed permits reduced
braking and smooth acceleration
changes.

∙ Select a gear range suitable to road

conditions.

5. Use Cruise Control

∙ Using cruise control during highway

driving 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

determine 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 cruis-
ing 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
effectively circulate the engine oil be-
fore driving.

∙ Your vehicle will reach its ideal oper-

ating

temperature

more

quickly

while driving versus idling.

FUEL EFFICIENT DRIVING TIPS

Starting and driving

10. Keeping your Vehicle Cool

∙ Park your vehicle in a covered parking

area or in the shade whenever pos-
sible.

∙ When entering a hot vehicle, opening

the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem.

∙ Keep your engine tuned up.

∙ Follow the recommended scheduled

maintenance.

∙ Keep the tires inflated to the correct

pressure. Low tire pressure increases
tire wear and lowers fuel economy.

∙ Keep the wheels in correct alignment.

Improper alignment increases tire wear
and lowers fuel economy.

∙ Use the recommended viscosity engine

oil. For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Technical and con-
sumer information” section of this
manual.

INCREASING FUEL ECONOMY

Starting and driving

WARNING

∙ Do not stop or park the vehicle over

flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.

∙ Safe parking procedures require that

both the parking brake be set and the
transmission placed into P (Park). Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and
result in an accident. Make sure the
shift lever has been pushed as far for-
ward as it can go and cannot be
moved without depressing the foot
brake pedal.

∙ Never leave the engine running while

the vehicle is unattended.

∙ To help avoid risk of injury or death

through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.

1. Firmly apply the parking brake.

2. Move the shift lever to the P (Park) po-

sition.

3. To help prevent the vehicle from rolling

into traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated.

∙ HEADED DOWNHILL WITH CURB

䊊

A

:

Turn the wheels into the curb and
move the vehicle forward until the curb
side wheel gently touches the curb.

∙ HEADED UPHILL WITH CURB

䊊

B

:

Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
