When driving
■Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco mode
Suitable for improving the fuel
economy, because the torque
corresponding to the accelera-
tor pedal depression amount
can be gener
ated more
smoothly than it is in normal
conditions and the operation of
the air conditioning system will
be minimized.
When the Eco mode switch is
pr
essed, the “ECO MODE”
indicator comes on in the meter.
Power mode
Suitable when the vehicle needs
to drive powerfully or travels in
mountainous areas.
When the power mode switch is
pr
essed, the “PWR MODE”
indicator comes on in the meter.

■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 15 mph [25 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
■When disconnecting and reconnecting battery terminals
The following information will be reset:
●Total distance/Total average fuel consumption
●Average fuel consumption after refueling
●Cruising range
●Average vehicle speed
■Customization
Settings (e.g. available languages) can be changed. 
(Customizable features P. 5 7 2 )
CAUTION
■Caution while driving
When operating the electronic feature control while driving, take extra notice of the
vehicle’s surrounding area.
NOTICE
■The multi-information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.

Touch tracer display function
The switch operation is shown on the head-up display when the steering
switch provided on the steering wheel is oper ated. The driver can oper-
ate the steering switch without s eeing it on the steering wheel.
The display will change in
r
esponse to steering switch opera -
tion.
Touching the steering switch will
cause the touch tracer display to
appear on the head-up display.

■Touch tracer display
Only the switch that is being
operated is highlighted, and
thus, the driv
er can perceive
which button is being operated.
The applicable switch displayed
on the head-up display will
change in r

esponse to the
switch operation.
Taking your finger off the steering
switch returns the display to the
vehicle speed indication.
It is possible to turn the touch
tr
acer display ON/OFF as neces -
sary. ( P. 1 8 1 )
Turn-by-turn navigation
When the vehicle approaches an
intersection, the direction the vehi -
cle should go is guided by the
arr

ow.
When the vehicle approaches an
intersection, the r
oute guidance
will start and the distance
* to the
intersection will also be displayed.
The animation guidance changes
according to the vehicle conditions
(running or stopped).
*:The distance decreases in incre -
ments of 50 yards and the dis -
tance indication will disappear
when the v
ehicle passes through
the intersection.

■Brightness of the head-up display
The headlight control sensor detects the brightne
ss of the area surrounding the
head-up display and adjusts th e brightness accordingly. (P. 1 8 6 )
■Head-up display
The head-up display may seem dark and hard to see when viewed through sun -
glasses, especially polarized sunglasses. 
Adjust the brightness of the head-up display or remove your sunglasses.
CAUTION
■Before using the head-up display
Check that the position and brightness of the head-up display image does not inter-
fere with safe driving. Incorrect adjustme nt of the image's position or brightness
may obstruct the driver's view and lead to an accident, resulting in death or serious
injury.
NOTICE
■To prevent damage to components
●Do not place any drinks near the head-up
display projector. If the projector gets wet,
electrical malfunctions may result.
●Do not place anything on or put stickers
onto the head-up display projector. 
Doing so could interrupt head-up display
indications.
●Do not touch the inside of the head-up dis-
play projector or thrust sharp edges or the
like into the projector. 
Doing so could cause mechanical malfunc-
tions.

When driving
■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown correspond
to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle distance increases/
decreases in accordance with vehicle speed.
■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canc eled if an obstruction is detected.
■Warning lights, messages and buzzer s for dynamic radar cruise control
Warning lights, messages and buzzers are us ed to indicate a system malfunction or
to inform the driver of the need for caution while driving. ( P. 493, 502, 505)
■Approach warning
In the following instances, there is a possibility that the warnings will not occur:
●When the speed of the vehicle ahead ma tches or exceeds your vehicle speed
●When the vehicle ahead is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●At the instant the accelerator is applied
Distance optionsVehicle-to-vehicle distance

■Certification
For vehicles sold in the U.S.A.
FCC ID: HYQDNMWR004
This device complies with Part 15 of the FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
FCC WARNING
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Radio frequency radiation exposure Information:
This equipment complies with FCC radiatio n exposure limits set forth for an uncon-
trolled environment.
This equipment should be installed and op erated with minimum distance of 20 cm
between the radiator (antenna) and your body.
This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
CAUTION
■Before using dynamic radar cruise control
Do not overly rely on vehicl e-to-vehicle distance control. 
Be aware of the set speed. If automatic deceleration/acceleration is not appropri-
ate, adjust the vehicle speed, as well as the distance between your vehicle and vehi-
cles ahead by applying the brakes etc.
■Cautions regarding the driving assist systems
Observe the following precautions. 
Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure following distance 
The dynamic radar cruise control is only in tended to help the driver in determin-
ing the following distance between the driver’s own vehicle and a designated
vehicle traveling ahead. It is not a mechanism that allows careless or inattentive
driving, and it is not a system that can assist the driver in low-visibility conditions. It
is still necessary for driver to pay clos e attention to the vehicle’s surroundings.

When driving
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■ Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding wh en swerving suddenly or turning on
slippery road surfaces
■ TRAC (Traction Control)
Helps to maintain drive power and prevents the drive wheels from spin -
ning when starting the vehicle or
accelerating on slippery roads
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■Enhanced VSC (Enhanced vehicle stability control)
Provides cooperative control of the ABS, TRAC, VSC and EPS. 
Helps to maintain directional stability when swerving on slippery road sur -
faces by controlling steering performance.
■ PCS (Pre-Collision System) (if equipped)
