Make sure the transfer 4LO position indicator
light turns on when you shift the 4WD shift switch
to 4LO.
The indicator light may blink while shifting
from one drive mode to the other.
The 4LO indicator light must stop blinking and
remain illuminated or turn off before shifting the
transmission into gear. If the shift selector is
shifted from the N (Neutral) position to any other
gear when the 4LO indicator light is blinking, the
vehicle may move unexpectedly.
When you shift between 4H and 4LO, follow the
instructions below:● For automatic transmission models, stop the
vehicle and shift the shift selector to the N
(Neutral) position with the brake pedal de-
pressed, then depress and turn the 4WD
shift switch to 4LO or 4H.
● For manual transmission models, stop the
vehicle and shift the shift selector to the N
(Neutral) position with the clutch pedal de-
pressed, then depress and turn the 4WD
shift switch to 4LO or 4H.
You cannot move the transfer 4WD shift switch
between 4H and 4LO unless you stop the vehicle
and shift the shift selector to the N position with
the brake pedal (A/T models) or clutch pedal
(M/T models) depressed.Turn signal/hazard indicator lights
The appropriate light flashes when the turn signal
switch is activated.
Both lights flash when the hazard switch is turned
on.
Vehicle Dynamic Control(VDC) OFF indicator light
This indicator light comes on when the Vehicle
Dynamic Control off switch is pushed to OFF, the
transfer case is in the 4LO position (
model) , or when the Vehicle Dynamic Control
system is not functioning properly. This indicates
the Vehicle Dynamic Control system is not oper-
ating.
Push the Vehicle Dynamic Control off switch
again or restart the engine and the system will
operate normally. See “Vehicle Dynamic Control
(VDC) system” in the “Starting and driving” sec-
tion of this manual.
The Vehicle Dynamic Control light also comes on
when you turn the ignition key to the ON position.
The light will turn off after about 2 seconds if the
system is operational. If the light stays on or
comes on along with the SLIP indicator light while you are driving, have the Vehicle Dynamic
Control system checked by a NISSAN dealer.
If the battery is removed or discharged, the Ve-
hicle Dynamic Control system is disabled and the
VDC indicator light will not turn off after 2 sec-
onds when the ignition switch is turned to the ON
position. To reset the system, you must perform
the reset procedure. Refer to “Vehicle Dynamic
Control (VDC) system” in the “Starting and driv-
ing” section of this manual.
If the light does not go off after performing the
reset procedure, have the traction control system
checked by a NISSAN dealer.
While the Vehicle Dynamic Control system is
operating, you might feel slight vibration or hear
the system working when starting the vehicle or
accelerating, but this is normal.
The VDC system will be disabled and the VDC
light will illuminate when the electronic locking
rear differential (E-lock) system switch (if so
equipped) is turned on and the E-lock system is
engaged. If the E-lock system disengages or the
switch is turned off, the VDC system will be
enabled and the VDC light will turn off.

Shift lock release
If the battery is discharged, the shift selector may
not be moved from the P (Park) position even with
the brake pedal depressed.
To move the shift selector, release the shift lock.
The shift selector can be moved to N (Neutral) .
However, the steering wheel will be locked un-
less the ignition switch is placed in the ON posi-
tion (for models with a steering lock mechanism) .
This allows the vehicle to be moved if the battery
is discharged.To push the shift lock release, complete the fol-
lowing procedure:
1. Place the ignition switch in the LOCK posi- tion and remove the key.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Use a protective cloth on the tip of a small screwdriver before inserting it in the shift
lock release slot and pushing down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
6. Place the ignition switch in the ON position to unlock the steering wheel (for models with
a steering lock mechanism) .
7. Now the vehicle may be moved to the de- sired location.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires. 3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra washer fluid to refill the windshield-
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
●Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
COLD WEATHER DRIVING
5-38Starting and driving

WARNING
Always follow the instructions below.
Failure to do so could result in damage to
the charging system and cause personal
injury.1. If the booster battery is in another vehicle, position the two vehicles to bring their bat-
teries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Move the shift se- lector to N (Neutral) (manual transmission)
or to P (Park) (automatic transmission) . Switch off all unnecessary electrical sys-
tems (lights, heater, air conditioner, etc.) .
3. Remove vent caps on the battery (if so equipped) . Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence il- lustrated (
A,B,C,D).
CAUTION
●Always connect positive () to positive
() and negative () to body ground (for
example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery. ●
Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
5. Start the engine of the booster vehicle and let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm, and start the en-
gine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, turn the key off and
wait 3 to 4 seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.
8. Replace the vent caps (if so equipped) . Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
