tion.
. Allow more stopping distance
under these conditions. Braking
should be started sooner than on
dry pavement.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare
ice). These may appear on an
otherwise clear road in shaded
areas. If a patch of ice is seen
ahead, brake before reaching it.
Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous ex-
haust gases under your vehicle.
Keep snow clear of the exhaust
pipe and from around your vehi-
cle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the en-
gine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours,
depending on outside temperatures,
to properly warm the engine coolant.
Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it
away from moving parts.
WARNING
.Do not use your engine block
heater with an ungrounded elec-
trical system or a 2-pronged
adapter. You can be seriously
injured by an electrical shock if
you use an ungrounded connec-
tion. .
Disconnect and properly store the
engine block heater cord before
starting the engine. Damage to
the cord could result in an elec-
trical shock and can cause ser-
ious injury.
. Use a heavy-duty 3-wire, 3-
pronged extension cord rated
for at least 10A. Plug the exten-
sion cord into a Ground Fault
Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure
to use the proper extension cord
or a grounded outlet can result in
a fire or electrical shock and
cause serious personal injury.

6-18In case of emergency
2. Turn off the air conditioner. Open allthe windows, move the heater or air
conditioner temperature control to
maximum hot and fan control to high
speed.
3. If engine overheating is caused by climbing a long hill on a hot day, run
the engine at a fast idle (approxi-
mately 1,500 rpm) until the tempera-
ture gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from
the radiator before opening the hood.
(If steam or coolant is escaping, turn
off the engine.) Do not open the hood
further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent get-
ting burned.
6. Visually check if the cooling fan is running. The radiator hoses and ra-
diator should not leak water. If coolant
is leaking or the cooling fan does not
run, stop the engine.
WARNING
Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, engine
belts or the engine cooling fan. The
engine cooling fan can start at any
time.
7. After the engine cools down, check the coolant level in the reservoir with
the engine running. Add coolant to
the reservoir if necessary. Have your
vehicle repaired. It is recommended
you visit a NISSAN dealer for this
service.

JVM0087X
CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is running and after it
reaches normal operating temperature.
If the coolant level is below the MIN level
,
add coolant up to the MAX level. If the
reservoir is empty, check the coolant level
in the radiator when the engine is cold.
If there is insufficient coolant in the
radiator, fill the radiator with coolant up
to the radiator filler cap above the radia-
tor upper hose opening and also add it to
the reservoir up to the MAX level
. Put on
the filler cap above the radiator upper
hose and with the reservoir cap open,
start the engine. Run the engine until it
reaches normal operating temperature. Add coolant up to the MAX level
. Tighten
the cap securely after adding engine
coolant.
If the cooling system requires coolant
frequently, have it checked. It is recom-
mended you visit a NISSAN dealer for
this service.
CHANGING ENGINE COOLANT
It is recommended that major cooling
system repairs be performed by a NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.
WARNING
. To avoid the danger of being
scalded, never change the cool-
ant when the engine is hot.
. Never remove the radiator cap
when the engine is hot. Serious
burns could be caused by high
pressure fluid escaping from the
radiator.
. Avoid direct skin contact with
used coolant. If skin contact is
made, wash thoroughly with soap or hand cleaner as soon as pos-
sible.
. Keep coolant out of reach of
children and pets.
Engine coolant must be disposed of
properly. Check your local regulations.
