Dome Lamp Override

E(Dome Lamp Override): You can use the dome

override button, located below the exterior lamps control,

to set the dome and footwell lamps to come on

automatically when a door is opened, or to remain off.

To turn the lamps off, press the button into the in position.

With the button in this position, the dome lamps will

remain off when the doors are open. To return the lamps

to automatic operation, press the button again and return

it to the out position. With the button in this position, the

dome lamps will come on when you open a door.

Exit Lighting

With exit lighting, the interior lamps will come on when

you remove the key from the ignition. The lamps will not

come on if the dome override button is pressed in.

Electric Power Management

The vehicle has Electric Power Management (EPM) that

estimates the battery’s temperature and state of charge.

It then adjusts the voltage for best performance and

extended life of the battery.

When the battery’s state of charge is low, the voltage is

raised slightly to quickly put the charge back in. When

the state of charge is high, the voltage is lowered slightly

to prevent overcharging. If the vehicle has a voltmeter

gage, you may see the voltage move up or down. This is

normal. If there is a problem, an alert will be displayed.

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.

A high electrical load occurs when several of the following

loads are on: headlamps, high beams, fog lamps, rear

window defogger, climate control fan at high speed,

heated seats, engine cooling fans, trailer loads, and

loads plugged into accessory power outlets.
