•The hill descent control may not con-
trol the vehicle speed on a hill under
all load or road conditions. Always be
prepared to depress the brake pedal
to control vehicle speed. Failure to do
so may result in a collision or serious
personal injury.
CAUTION
When the hill descent control system op-
erates continuously for a long time, the
temperature of the brake pads may in-
crease and the hill descent control sys-
tem may be temporarily disabled (the in-
dicator light will blink). If the indicator
light does not come on continuously af-
ter blinking, stop using the system.
The hill descent control system is designed
to reduce driver workload when going down
steep hills. The hill descent control system
helps to control vehicle speed so the driver
can concentrate on steering the vehicle.
To activate the hill descent control system:
• The shif t lever must be in forward or re- verse gear,
• The 4WD switch must be in the 4L posi- tion and the vehicle speed must be under
15 mph (25 km/h) or • The 4WD switch must be in the 4H posi-
tion and the vehicle speed must be under
21 mph (35 km/h), and
• The hill descent control system switch must be ON.
The hill descent control system ON indica-
tor light will come on when the system is
activated. Also, the stop/tail lights illumi-
nate while the hill descent control system
applies the brakes to control vehicle speed.
If the accelerator or brake pedal is depressed
while the hill descent control system is on,
the system will stop operating temporarily.
As soon as the accelerator or brake pedal is
released, the hill descent control system be-
gins to function again if the hill descent con-
trol operating conditions are fulfilled.
The hill descent control system ON indica-
tor light blinks if the switch is on and all
conditions for system activation are not
met or if the system becomes disengaged
for any reason.
To turn off the hill descent control system,
push the switch to the OFF position.
For additional information, refer to “Hill de-
scent control system ON indicator light” in
this section and “Hill descent control sys-
tem” in the “Starting and driving” section of
this manual. The E-Lock system can help provide added
traction if the vehicle is stuck or becoming
stuck.
To activate the E-Lock system:
• The 4WD switch must be in the 4LO posi-
tion (4-Wheel Drive vehicles),
• The vehicle must be stopped or moving at 4 mph (7 km/h) or less, and
• The E-Lock system switch must be turned on.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most radio frequency de-vices such as garage doors, gates, home
and office lighting, entry door locks and
security systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the ve-
hicle's battery is discharged or is discon-
nected, HomeLink® will retain all pro-
gramming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, refer to “Programming
HomeLink®” in this section.WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982). A
garage door opener which cannot
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse, does not meet
current federal safety standards. Us-
ing a garage door opener without
these features increases the risk of
serious injury or death. •
During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage
door, gate, etc. that you are
programming.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON posi-
tion (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio frequency.

3-12Pre-driving checks and adjustments

When installing a CB, ham radio or car
phone in your vehicle, be sure to observe
the following precautions; otherwise, the
new equipment may adversely affect the
engine control system and other electronic
parts.CAUTION
• Keep the antenna as far away as pos-
sible from the electronic control
modules.
• Keep the antenna wire more than 8 in
(20 cm) away from the electronic
control system harnesses. Do not
route the antenna wire next to any
harness.
• Adjust the antenna standing-wave
ratio as recommended by the
manufacturer.
• Connect the ground wire from the CB
radio chassis to the body.
• For additional information, it is rec-
ommended that you visit a NISSAN
dealer.
• Do not ground electrical accessories
directly to the battery terminal. Do-
ing so will bypass the variable volt-
age control system and the vehicle
battery may not charge completely.
For additional information, refer to
“Variable voltage control system” in
the “Do-it-yourself ” section of this
manual.
• Use electrical accessories with the
engine running to avoid discharging
the vehicle battery.WARNING
• Use a phone af ter stopping your ve-
hicle in a safe location. If you have to
use a phone while driving, exercise
extreme caution at all times so full
attention may be given to vehicle
operation.
• If you are unable to devote full atten-
tion to vehicle operation while talk-
ing on the phone, pull off the road to
a safe location and stop your vehicle.
