6-6 Lighting
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 of 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
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 DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible. See
Battery Voltage and Charging
Messages on page 5‑26.

10-30 Vehicle Care
Headlamp Aiming
The headlamp aiming system has
been preset at the factory.
If the vehicle is damaged in an
accident, the aim of the headlamps
may be affected and adjustment
may be necessary.
It is recommended that a dealer
adjust the headlamps. To re-aim the
headlamps yourself, use the
following procedure.
The vehicle should be properly
prepared as follows. The vehicle:
.Should be placed so the
headlamps are 7.6 m (25 ft) from
a light colored wall.
.Must have all four tires on a
level surface which is level all
the way to the wall.
.Should be placed so it is
perpendicular to the wall or other
flat surface.
.Should not have any snow, ice,
or mud on it.
.Should be fully assembled and
all other work stopped while
headlamp aiming is being
performed.
.Should be normally loaded with
a full tank of fuel and one person
or 75 kg (160 lbs) sitting in the
driver's seat.
.Tires should be properly inflated.
Headlamp aiming is done with the
vehicle's low-beam headlamps. The
high-beam headlamps will be
correctly aimed if the low-beam
headlamps are aimed properly. To adjust the vertical aim, do the
following:
1. Open the hood. See
Hood on
page 10‑5 for more information.
2. Locate the aim dot on the lens of
the low‐beam headlamp.
3. Measure the distance from the ground to the aim dot on the
low‐beam headlamp. Record the
distance.
