Engine Power Messages
ENGINE POWER IS REDUCED
This message displays when the
vehicle’s propulsion power is
reduced. A reduction in propulsion
power can affect the vehicle's ability
to accelerate. If this message is on,
but there is no observed reduction
in performance, proceed to your
destination. The performance may be reduced the next time the vehicle
is driven. The vehicle may be driven
while this message is on, but
maximum acceleration and speed
may be reduced. Anytime this
message stays on, or displays
repeatedly, the vehicle should be
taken to your dealer for service as
soon as possible.
Under certain operating conditions
propulsion will be disabled. Try
restarting after the vehicle has been
off for 30 seconds.
Vehicle Speed Messages
SPEED LIMITED TO XXX KM/

116 Lighting
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
needed. It can temporarily reduce
the power demands of some
accessories.
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 Driver Information
Center (DIC) message might be
displayed, such as SERVICE
BATTERY CHARGING SYSTEM.
If this messages displays, it isrecommended that the driver reduce
the electrical loads as much as
possible.
Battery Power Protection
This feature shuts off the dome
lamps if they are left on for more
than 10 minutes when the ignition is
off. This helps to prevent the battery
from running down.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition 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
Oposition and then back to
the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.

FM Stereo
FM stereo gives the best sound, but
FM signals reach only about 16 to
65 km (10 to 40 mi). Tall buildings or
hills can interfere with FM signals,
causing the sound to fade in
and out.
Cellular Phone Usage
Cellular phone usage may cause
interference with the radio. This
interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to the
radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Multi-Band Antenna
The multi-band antenna is on the
roof of the vehicle. The antenna is
used for the Navigation System,
OnStar and the SiriusXM Satellite
Radio Service System if the vehicle
has these features. Tall buildings,
hills, trees, heavy foliage, tunnels,bridges, and garages will affect
reception. Keep the antenna clear of
obstructions for clear reception.

clearance when entering garages or
parking structures.

It could get caught in the CD player.
If a CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners is not
advised, due to the risk of
contaminating the lens of the CD
optics with lubricants internal to the
CD player mechanism.
