Lighting 153
Lighting Features
Entry Lighting
Some exterior lamps and most of
the interior lights turn on briefly
when the Remote Keyless Entry
(RKE) transmitter
Kbutton is
pressed. After about 30 seconds the
exterior lamps turn off, then the
dome lamps and remaining interior
lights dim to off. Entry lighting can
be disabled manually by changing
the ignition out of the OFF position,
or by pressing the RKE transmitter
Qbutton.
This feature can be changed. See
Vehicle Personalization 0138.
Exit Lighting
Some exterior lamps come on at
night, or in areas with limited
lighting, when the key is removed
from the ignition. The dome lamps
also come on when the key is
removed from the ignition. The
exterior lamps and dome lamps remain on after the door is closed
for a set amount of time, then
automatically turn off.
For vehicles with Keyless Access,
the exterior lamps automatically turn
on when a door is opened after the
ignition is changed to the OFF
position. The dome lamps also
come on after the ignition is
changed to the OFF position. See
Ignition Positions (Keyless Access)
0
201 orIgnition Positions (Key
Access) 0203.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization 0138.
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. 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 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 that is 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.

The following are climate control
settings that use more fuel:
.
Comfort air conditioning mode.

. Extreme temperature settings,
such as 15 °C (60 °F) or 32 °C
(90 °F).
. High fan speed settings.
To help reduce fuel usage:
. Use the full automatic control as
described under “Automatic
Operation.”
. Use eco air conditioning, instead
of the comfort air conditioning.
. Select a temperature setting that
is higher in hot weather and
lower in cold weather.
. Turn off the air conditioning
when it is not needed.
. Only use defrost when needed
to clear the windows.

Driving and Operating 195
under these conditions. For
information on how to check and
add oil, seeEngine Oil0255.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
(Continued)
Warning (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0283.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.

244 Driving and Operating
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. If the overheat warning
comes on, seeEngine Overheating
0 264.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill. 2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in place, release the regular
brakes until the chocks absorb
the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See
Maintenance Schedule 0325.
Things that are especially important
in trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system, and
brake system. It is a good idea to
inspect these before and during
the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Trailer Towing (Bi-Fuel)
The vehicle is neither designed nor
intended to tow a trailer.
Trailer Towing (All except
Bi-Fuel)
Before pulling a trailer, three
important considerations have to do
with weight:
. Weight of the trailer.
. Weight of the trailer tongue.
