Turning On and Enabling IntelliBeam

There is a sensor near the top center of the

windshield that automatically controls the

system. Keep this area of the windshield

clear of debris to allow for best system

performance.

The high beams may not turn off

automatically if the system cannot detect

another vehicle's lamps because of any of

the following:

.

The other vehicle’s lamps are missing,

damaged, obstructed from view,

or otherwise undetected.

The high-beam headlamps remain on, under

the automatic control, until one of the

following situations occurs:

.

The other vehicle’s lamps are covered

with dirt, snow, and/or road spray.

The other vehicle’s lamps cannot be

detected due to dense exhaust, smoke,

fog, snow, road spray, mist, or other

airborne obstructions.

.

The system detects an approaching

vehicle's headlamps.

The system detects a preceding vehicle's

taillamps.

The outside light is bright enough that

high-beam headlamps are not required.

The vehicle speed drops below 20 km/h

(12 mph).

The DRL system comes on when the

following conditions are met:

Exterior Lamps Off Reminder

Flash-to-Pass

A reminder chime sounds when the

headlamps or parking lamps are manually

turned on, the vehicle is turned off, and a

door is open. To disable the chime, turn the

instrument panel lights, and other lamps

will not turn on.

Headlamp High/Low-Beam

Changer

Push the turn signal lever toward the

instrument panel to change the headlamps

from low to high beam.

If the headlamps are in the automatic

position or on low beam, the high-beam

headlamps will turn on. Depending on the

type of headlamp, they will either turn off

after a short duration or stay on as long as

you hold the lever toward you. The

high-beam indicator on the instrument

cluster will come on. Release the lever to

return to normal operation.

When it begins to get dark, the automatic

headlamp system switches from DRL to the

headlamps.

Pull or push the turn signal lever to return

to low-beam headlamps.

To turn off the DRL, turn the exterior lamp

control to O and then release. For vehicles

first sold in Canada, turning off the DRL will

only work when the vehicle is parked.

Daytime Running Lamps (DRL)

DRL can make it easier for others to see the

front of the vehicle during the day. Fully

functional DRL are required on all vehicles

first sold in Canada.

Automatic Headlamp System

When the exterior lamp control is set to

AUTO and it is dark enough outside, the

headlamps come on automatically.

If after signaling a turn or a lane change the

arrows flash rapidly or do not come on, a

signal bulb could be burned out. If equipped

with LED turn signals, see your dealer.

Turn and Lane-Change Signals

Replace any burned out bulbs. If a bulb is

not burned out, check the fuse. See Fuses

and Circuit Breakers 0 362.

Turn Signal On Chime

If equipped, the fog lamp control is near the

exterior lamp control to the left of the

steering column.

If the turn signal is left on for more than

1.2 km (0.75 mi), a chime sounds at each

flash of the turn signal. A message may

appear in the Driver Information Center

(DIC). See Vehicle Messages 0 134. To turn

the chime and message off, move the turn

signal lever to the off position.

An arrow on the instrument cluster flashes

146

Lighting

Entry lighting can be disabled manually by

closing all doors, pressing Q on the remote

key, or starting the vehicle.

Battery Load Management

The vehicle has Electric Power Management

(EPM), which estimates the battery's

temperature and state of charge. It then

adjusts the voltage for best performance

and extended life of the battery.

This feature can be changed. On the

infotainment home page, select Settings T

Vehicle T Vehicle Locator Lights.

When the battery's state of charge is low,

the voltage is raised slightly to quickly bring

the charge back up. When the state of

charge is high, the voltage is lowered

slightly to prevent overcharging. The

voltmeter gauge or the voltage display on

the Driver Information Center (DIC),

if equipped, may show the voltage moving

up or down. This is normal. If there is a

problem, an alert will be displayed.

Exit Lighting

Some exterior lamps and interior lamps turn

on when the driver door is opened after the

vehicle is turned off.

Press the lamp lens to turn the rear reading

lamps on or off.

Lighting Features

The exterior and interior lamps remain on

for a set amount of time, then automatically

turn off.

Entry Lighting

The interior lamps turn on when pressing K

on the remote key or opening any doors,

and the dome lamp control is in the door

position.

The interior lights turn on when the vehicle

is turned off.

The battery can be discharged at idle if the

electrical loads are very high. This is true for

all vehicles. This is because the generator

(alternator) may not be spinning fast

enough at idle to produce all the power that

is needed for very high electrical loads.

The exterior lamps turn off immediately by

turning the exterior lamp control off.

heated seats, engine cooling fans, trailer

power outlets.

Exterior Lighting Battery Saver

EPM works to prevent excessive discharge of

the battery. It does this by balancing the

generator's output and the vehicle's

electrical needs. It can increase engine idle

speed to generate more power, whenever

needed. It can temporarily reduce the power

demands of some accessories.

The exterior lamps turn off about 10 minutes

after the vehicle is turned off, if the parking

lamps or headlamps have been manually

left on. This protects against draining the

battery. To restart the 10-minute timer, turn

the exterior lamp control to the O position

and then back to the ; or 2 position.

Normally, these actions occur in steps or

levels, without being noticeable. In rare

cases at the highest levels of corrective

action, this action may be noticeable to the

driver. If so, a DIC message might be

displayed and it is recommended that the

driver reduce the electrical loads as much as

possible.

To keep the lamps on for more than

10 minutes, the vehicle must be on or in

accessory mode.

Battery Power Protection

This feature helps prevent the battery from

being drained if the interior courtesy lamps

or reading lamps are accidentally left on.

If any of these lamps are left on, they

automatically turn off after 10 minutes if the

ignition is off. The cargo lamp shuts off

after 20 minutes if the ignition is off.

The lamps will not come back on again until

one of the following occurs:
