Lighting Features
Entry Lighting
Some exterior lamps and interior
lamps turn on briefly at night, or in
areas with limited lighting, when
K
is pressed on the Remote Keyless
Entry (RKE) transmitter. When a
door is opened, the interior lamps
come on if the dome lamp control is
in the Door position. They stay on
for about 20 seconds. When all of
the doors have been closed or the
ignition is turned on, they gradually
fade out.
This feature can be changed. See
“Vehicle Locator Lights”under
Vehicle Personalization 0129.
Exit Lighting
Some exterior lamps and interior
lamps come on at night, or in areas
with limited lighting, when the key is
removed from the ignition. The
exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off. If equipped with Keyless Access,
the exterior lamps automatically turn
on when a door is opened after the
ignition is turned off. The dome
lamps also come on after the
ignition is turned off.
See
Ignition Positions (Key Access)
0 181 orIgnition Positions (Keyless
Access) 0183.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization 0129.
Battery Load
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 bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), 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 needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: 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.
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

Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.

Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal to the floor
and start the engine.
Starting Procedure
Key Access
1. With your foot off the accelerator pedal, turn the
ignition to START. When the
engine cranks, let go of the
key. The idle speed will go
down as the engine gets warm.
Caution
Holding the key in START for
longer than 15 seconds at a time
will cause the battery to be
drained much sooner. And the
excessive heat can damage the
starter motor. Wait about
15 seconds between each try to
help avoid draining the battery or
damaging the starter.
2. If the engine does not start, wait about 15 seconds and try
again. Wait about 15 seconds
between each try.
When the engine has run about
10 seconds to warm up, the
vehicle is ready to be driven.
Do not run the engine at high
speed when it is cold.
If the weather is below freezing
(0 °C or 32 °F), let the engine
run for a few minutes to
warm up. 3. If the engine still will not start,
or starts but then stops, 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
about three seconds. If the
vehicle starts briefly but then
stops again, do the same thing,
but this time keep the pedal
down for five or six seconds.
This clears the extra gasoline
from the engine.
Keyless Access 1. With the Keyless Access system, the RKE transmitter
must be in the vehicle. Press
ENGINE START/STOP with the
brake pedal applied. When the
engine begins cranking, let go
of the button.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
