.Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system, including
reduced performance or a false acti-
vation.
. The system is not designed to pre-
vent contact with small or moving
objects.
. The system will not detect small
objects below the bumper, and may
not detect objects close to the bum-
per or on the ground.
. The system may not detect the
following objects:
— Fluffy objects such as snow, cloth, cotton, grass or wool.
— Thin objects such as rope, wire or chain. — Wedge-shaped objects.
. If your vehicle sustains damage to the
bumper fascia, leaving it misaligned
or bent, the sensing zone may be
altered causing inaccurate measure-
ment of objects or false alarms.
CAUTION
Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
System temporarily unavailable
When the amber markers are displayed at
the corners of the vehicle icon and the
function cannot be activated from the
Parking sonar settings menu (the setting
items are grayed out), the sonar system may
be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar (located on
the front and rear bumper fascia) free
from accumulations of snow, ice and dirt.
Do not scratch the surface of the sonar
when cleaning. If the sensors are cov-
ered, the accuracy of the sonar function

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals outside
the vehicle to help you inflate the tires to the
recommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the
shift lever in the P (Park) position.
3. Place the ignition switch in the ON position. Do not start the engine. Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire.
. If the tire is over-inflated more than
approximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash 3
times. To correct the pressure, push the
core of the valve stem on the tire briefly
to release pressure. When the pressure
reaches the designated pressure, the
horn beeps once.
. If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates
that the Tire Inflation Indicator is not
operating.
. The TPMS will not activate the Tire
Inflation Indicator under the following
conditions:
— If there is interference from an ex- ternal device or transmitter
— The air pressure from the inflation device such as those using a power
socket is not sufficient to inflate the
tire

Some indicators and warnings for operation
are displayed in the vehicle information
display between the speedometer and tach-
ometer. (See “Vehicle information display”
(P.2-19).)
The ignition lock is designed so that the
ignition switch position cannot be switched
to LOCK until the shift lever is moved to the
P (Park) position.
When the ignition switch cannot be pushed
toward the LOCK position, proceed as
follows:
1. Move the shift lever into the P (Park)position.
2. Push the ignition switch to the OFF position. The ignition switch position
indicator will not illuminate.
3. Open the door. The ignition switch will change to the LOCK position.
The shift lever can be moved from the P
(Park) position if the ignition switch is in the
ON position and the brake pedal is de-
pressed.PUSH-BUTTON IGNITION

Starting and driving5-13

1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N(Neutral) position. (P is recommended.)
The starter is designed not to operate
unless the shift lever is in either of the
above positions.
3. Push the ignition switch to the ON position. Firmly depress the brake pedal
and push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the
ignition switch in any position.
.If the engine is very hard to start inextremely cold weather or when re-
starting, depress the accelerator ped-
al a little (approximately 1/3 to the
floor) and while holding, crank the
engine. Release the accelerator pedal
when the engine starts.
.If the engine is very hard to start
because it is flooded, depress the
accelerator pedal all the way to the
floor and hold it. Push the ignition
switch to the ON position to start
cranking the engine. After 5 or 6
seconds, stop cranking by pushing
the ignition switch to OFF. After
cranking the engine, release the accel-
erator pedal. Crank the engine withyour foot off the accelerator pedal
by
depressing the brake pedal and push-
ing the push-button ignition switch to
start the engine. If the engine starts,
but fails to run, repeat the above
procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, push the ignition switch to
OFF and wait 10 seconds before crank-
ing again, otherwise the starter could be
damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the
engine while warming it up. Drive at
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 - 3 minutes before shut-
ting it off. Starting and stopping the
engine over a short period of time may
make the vehicle more difficult to start.
When racing the engine up to 4,500 rpm
or more under no load condition, the
engine will enter the fuel cut mode. 5. To stop the engine, shift the shift lever to
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 discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. 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 (if so
equipped)
Vehicles started with the remote engine
start function require the ignition switch to
be placed in the ON position before the shift
lever can be moved from the P (Park)
position. To place the ignition switch in the
ON position, perform the following steps:
1. Make sure that the Intelligent Key is on you.
2. Depress the brake pedal.
3. Push the ignition switch once to the ON position.

The automatic transmission in your vehicle is
electronically controlled by a transmission
control module to produce maximum effi-
ciency and smooth operation.
Shown on the following pages are the
recommended operating procedures for this
transmission. Follow these procedures for
maximum vehicle performance and driving
enjoyment.
Starting the vehicle
After starting the engine, fully depress the
foot brake pedal and push the shift lever
button before shifting the shift lever to the R
(Reverse), N (Neutral), D (Drive) or Manual
shift mode position. Be sure the vehicle is
fully stopped before attempting to shift the
shift lever.
This Automatic Transmission (AT) model is
designed so that the foot brake pedal must
be depressed before shifting from P (Park)
to any drive position while the ignition
switch is in the ON position.
The shift lever cannot be moved out of the P
(Park) position and into any of the other
gear positions if the ignition switch is placed
in the LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed andpush the shift lever button to shift into a
driving gear. 2. Release the parking brake and foot
brake, then gradually start the vehicle in
motion.
WARNING
.Do not depress the accelerator pedal
while shifting from P (Park) or N
(Neutral) to R (Reverse), D (Drive) or
manual shift mode. Always depress
the brake pedal until shifting is
completed. Failure to do so could
cause you to lose control and have
an accident.
. Cold engine idle speed is high, so use
caution when shifting into a forward
or reverse gear before the engine has
warmed up.
. Never shift to either P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
moving reversing. This could cause an
accident or damage the transmission.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
