system could result in serious injury or
death.
∙ The I–DA system is only a warning to inform the driver of a potential lack of
driver attention or drowsiness. It will
not steer the vehicle or prevent loss of
control.
∙ The I–DA system does not detect and provide an alert of the driver’s lack of
attention or fatigue in every situation.
∙ It is the driver’s responsibility to: ∙ stay alert,
∙ drive safely,
∙ keep the vehicle in the travelinglane,
∙ be in control of the vehicle at all times,
∙ avoid driving when tired,
∙ avoid distractions (texting, etc).
The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
INTELLIGENT DRIVER ALERTNESS
(I-DA)
Starting and driving5-159

The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.
INTELLIGENT DRIVER ALERTNESS
SYSTEM OPERATION
If the system detects driver fatigue or that
driver attention is decreasing, the mes-
sage “Take a break?” appears in the vehicle
information display and a chime sounds
when the vehicle is driven at speeds above
37 mph (60 km/h).
The system continuously monitors driver
attention and can provide multiple warn-
ings per trip.The system resets and starts reassessing
driving style and steering behavior when
the ignition switch is cycled from the ON to
the OFF position and back to the ON posi-
tion.

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.
