Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in every
Canadian province says children up to some age must
be restrained while in a vehicle.
{WARNING:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
Airbags plus lap‐shoulder belts offer protection for
adults and older children, but not for young children and
infants. Neither the vehicle's safety belt system nor its
airbag system is designed for them. Every time infants
and young children ride in vehicles, they should have
the protection provided by appropriate child restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
{WARNING:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a child
will become so heavy it is not possible to hold it
during a crash. For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) infant will
suddenly become a 110 kg (240 lb) force on a
person's arms. An infant should be secured in an
appropriate restraint.

Starting Procedure
1. With your foot off the accelerator pedal, turn theignition to START. When the engine starts, let go of
the key. The idle speed will slow down as the
engine warms. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is
turned to the START position, and then released
when the engine begins cranking, the engine will
continue cranking for a few seconds or until the
vehicle starts. If the engine does not start and the
key is held in START, cranking will be stopped
after 15 seconds to prevent cranking motor
damage. To prevent gear damage, this system also
prevents cranking if the engine is already running.
Engine cranking can be stopped by turning the
ignition switch to the ACC/ACCESSORY or LOCK/
OFF position.
Notice: Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down. 2. If the engine does not start after 5‐10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for up to a maximum of 15 seconds. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briefly but then stops again, repeat
these steps. This clears the extra gasoline from the
engine. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently until the oil warms up and lubricates all
moving parts.
Notice: The engine is designed to work with the
electronics in the vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer/retailer. If you
do not, the engine might not perform properly. Any
resulting damage would not be covered by the
vehicle warranty.

Resetting the Power Foldaway Mirrors
Reset the power foldaway mirrors if:
.The mirrors are accidentally obstructed while
folding.
.They are accidentally manually folded/unfolded.
.The mirrors will not stay in the unfolded position.
.The mirrors vibrate at normal driving speeds.
Fold and unfold the mirrors one time using the mirror
controls to reset them to their normal position.
A popping noise may be heard during the resetting of
the power foldaway mirrors. This sound is normal after
a manual folding operation.
Automatic Dimming
The driver outside mirror adjusts for the glare of the
headlamps behind you. See Automatic Dimming
Rearview Mirror
on page 3‑39for more information.
Turn Signal Indicator
The vehicle may also have a turn signal indicator on the
mirror. An arrow on the mirror flashes in the direction of
the turn or lane change.
Park Tilt Mirrors
If the vehicle has the memory package, the passenger
and/or driver mirror tilts to a preselected position when
the vehicle is in R (Reverse). This feature lets the driver
view the curb when parallel parking. The mirror(s) return
to the original position when the vehicle is shifted out of
R (Reverse), or the ignition is turned off or to
OFF/LOCK.
Turn this feature on or off through the Driver Information
Center (DIC). See DIC Vehicle Customization (With DIC
Buttons)
on page 4‑67for more information.

When the System Does Not Seem To
Work Properly
The rear vision camera system might not work properly
or display a clear image if:
.The RVC is turned off. See“Turning the Rear
Camera System On or Off” earlier in this section.
.It is dark.
.The sun or the beam of headlights is shining
directly into the camera lens.
.Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
.The back of the vehicle is in an accident, the
position and mounting angle of the camera can
change or the camera can be affected. Be sure to
have the camera and its position and mounting
angle checked at your dealer/retailer. The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to
one of the following conditions. If this occurs the left
indicator light on the mirror will flash.
.A slow flash may indicate a loss of video signal,
or no video signal present during the reverse cycle.
.A fast flash may indicate that the display has been
on for the maximum allowable time during a
reverse cycle, or the display has reached an Over
Temperature limit.
The fast flash conditions are used to protect the
video device from high temperature conditions.
Once conditions return to normal the device will
reset and the green indicator will stop flashing.
During any of these fault conditions, the display will be
blank and the indicator will continue to flash as long as
the vehicle is in R (Reverse) or until the conditions
return to normal.
Pressing and holding
zwhen the left indicator light is
flashing will turn off the video display along with the left
indicator light.

Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the
left of the steering wheel.
It controls the following systems:
.Headlamps
.Taillamps
.Parking Lamps
.License Plate Lamps
.Instrument Panel Lights
The exterior lamps control has four positions:
O(Off): Turns off the automatic headlamps and
daytime running lamps (DRL). Turn the headlamp
control to the off position again to turn the automatic
headlamps or DRL back on.
For vehicles first sold in Canada, the off position will
only work when the vehicle is shifted into P (Park). AUTO (Automatic) :
Automatically turns on the
headlamps at normal brightness, together with the
following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
When the vehicle is turned off and the headlamps are in
AUTO, the headlamps may automatically remain on for
a set time. The time of the delay can be changed using
the DIC. See Driver Information Center (DIC)
on
page 4‑44(If Equipped).
; (Parking Lamps) : Turns on the parking lamps
together with the following:
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
4-10

2(Headlamps) : Turns on the headlamps together with
the following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
When the headlamps are turned on while the vehicle is
on, the headlamps turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will
stay on for 10 minutes before automatically turning off
to prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
Push the turn signal/multifunction lever toward the
instrument panel to change the headlamps from low
beam to high beam.
Headlamps on Reminder
A reminder chime will sound when the headlamps or
parking lamps are manually turned on and the ignition is
off, in LOCK/OFF, ACC/ACCESSORY, or a door is
open. Turn the light off, then back on, to stop the chime.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
The DRL system comes on when the following
conditions are met:
.The ignition is on.
.The exterior lamps control is in AUTO.
.The engine is running.
.The light sensor determines it is daytime.
When the DRL system is on, only the DRL lamps are
on. The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
When it begins to get dark, the automatic headlamp
system switches from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles first sold in Canada, the transmission must be
in the P (Park) position, before the DRL lamps can be
turned off.
4-11

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system turns on the headlamps at the normal
brightness, along with the taillamps, sidemarker, parking
lamps, and the instrument panel lights. The radio lights
will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release it. For vehicles first sold in Canada, the
transmission must be in the P (Park) position, before the
automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel in the defroster grille that regulates
when the automatic headlamps turn on. Do not cover
the sensor or the headlamps will come on whenever the
ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lightsdoes not affect the system. The DRL and automatic
headlamp system is only affected when the light sensor
detects a change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough outside. During that
delay, the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. See
Instrument
Panel Brightness on page 4‑13.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). See DIC Vehicle
Customization (With DIC Buttons) on page 4‑67.
The regular headlamp system can be turned on when
needed.
