WARNING
∙ Your vehicle’s engine should beturned off while programming the
HomeLink® Universal Transceiver. For
additional information, refer to
“Push-button ignition switch” in the
“Starting and driving” section of this
manual. Do not breathe exhaust
gases; they contain colorless and
odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause
unconsciousness or death.
∙ Do not use the HomeLink® Universal Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse does not meet cur-
rent federal safety standards. Using a
garage door opener without these
features increases the risk of serious
injury or death. ∙ During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage door,
gate, etc., that you are programming.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON posi-
tion (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
1in view.

∙ If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch
to the ON position to start cranking
the engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition switch to the LOCK position. Af ter
cranking the engine, release the ac-
celerator pedal. Crank the engine
with your foot off the accelerator
pedal by depressing the brake pedal
and pushing the ignition switch to
start the engine. If the engine starts,
but fails to run, repeat the above pro-
cedure.

5. To stop the engine, move the shif t leverto the P (Park) position and push the
ignition switch to the OFF position.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly
and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t

CONTINUOUSLY VARIABLE
TRANSMISSION (CVT)

CAUTION
∙ Except in an emergency, do not shif tto the N (Neutral) position while driv-
ing. Coasting with the transmission in
the N (Neutral) position may cause se-
rious damage to the transmission.
∙ To avoid possible damage to your ve- hicle, when stopping the vehicle on an
uphill grade, do not hold the vehicle by
depressing the accelerator pedal. The
foot brake should be used for this
purpose.
The CVT in your vehicle is electronically
controlled to produce maximum power
and smooth operation.
Follow these procedures for maximum ve-
hicle performance and driving enjoyment.
NOTE:
Engine power may be automatically re-
duced to protect the CVT if the engine
speed increases quickly when driving on
slippery roads or while being tested on
some dynamometers. 1. Automatic Emergency Braking (AEB)
2. Lane Departure Warning (LDW) when
shaded and Intelligent Lane Interven-
tion (I-LI) when solid
3. Blind Spot Warning (BSW)
Starting the vehicle
1. Af ter starting the engine, fully depress the foot brake pedal before moving the
shif t lever out of the P (Park) position.
The Continuously Variable Transmis-
sion is designed so the foot brake
pedal MUST be depressed before
shif ting from P (Park) to any drive po-
sition while the ignition switch is in
the ON position.The shif t lever can-
not be moved out of P (Park) and into
any of the other gear positions if the
ignition switch is placed in the LOCK
position.

WARNING
If the shif t lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and
others.
Drive sport mode switch
When the drive sport mode switch is
pushed with the shif t lever in the D (Drive)
position, the drive sport mode indicator in
the instrument panel illuminates. For addi-
tional information, refer to “Drive sport
mode indicator” in the “Instruments and
controls” section of this manual.
Use the drive sport mode when you need
improved engine braking.
To turn off the drive sport mode, push the
drive sport mode switch again. The drive
sport mode indicator will turn off.Each time the engine is started, or when
the shif t lever is shif ted to any position
other than D (Drive), the drive sport mode
will automatically turn off.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
when climbing steep grades in high tem-
peratures with heavy loads, such as when
towing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be limited.

∙ The ICC system does not react to sta-tionary and slow moving vehicles.
∙ Always drive carefully and attentively when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system.
To avoid serious injury or death, do
not rely on the system to prevent ac-
cidents or to control the vehicle’s
speed in emergency situations. Do
not use the ICC system except in ap-
propriate road and traffic conditions.
ICC system operation
The ICC system is designed to maintain a
selected distance from the vehicle in front
of you and can reduce the speed to match
a slower vehicle ahead. The system decel-
erates the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to 40% of the
vehicle’s total braking power. This system
should only be used when traffic condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change
gradually. If a vehicle moves into the travel-
ing lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer be- cause the ICC system cannot decelerate
the vehicle quickly enough. If this occurs,
the ICC system sounds a warning chime
and blinks the system display to notif y the
driver to take necessary action.
The ICC system cancels and a warning
chime sounds if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected ahead.
The ICC system operates as follows:
∙ When there are no vehicles traveling ahead, the ICC system maintains the
speed set by the driver. The set speed
range is between approximately 20 and
90 mph (32 and 144 km/h).
∙ When there is a vehicle traveling ahead, the ICC system adjusts the speed to
maintain the distance, selected by the
driver, from the vehicle ahead. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill. Once your
vehicle stops, the ICC system keeps the
vehicle stopped.
∙ When your vehicle is stopped for less than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically. ∙ When your vehicle is at a standstill for
more than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator pedal. The ICC system starts to
follow the vehicle ahead.
∙ When the vehicle traveling ahead moves to a different traveling lane, the
ICC system accelerates and maintains
vehicle speed up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traf-
fic congestion.
Starting and driving5-103

Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle conditions (for ex-
ample, if a vehicle is being driven with
some damage).
Acceleration when passing
When the ICC system is engaged above
37 mph and following a slower vehicle (be-
low ICC set speed), and the turn signal is
activated to the lef t, the ICC system will
automatically start to accelerate the ve-
hicle to help initiate passing on the lef t and
will begin to reduce the distance to vehicle
directly ahead. Only the lef t side turn signal
operates this feature. As the driver steers
the vehicle and moves into the passing
lane, if no vehicle is detected ahead the ICC
system will continue to accelerate to the
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing distance. Acceleration can be stopped
at any point by depressing the brake pedal
or the CANCEL switch on the steering
wheel.
