● The steering wheel is forcibly turned beyond
its operation limits.
● The battery voltage is reduced.
Repeated steering maneuvers that may activate
the protection mechanism will damage the
4WAS system.
WARNINGThe 4WAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving techniques.
Ultimately the responsibility for safety of self
and others rests in the hands of the driver.
Therefore only through attentive and careful
driving methods can the 4WAS system be fully
appreciated and safety optimized. FREEING A FROZEN DOOR LOCK To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTIFREEZE In the winter when it is anticipated that the
outside temperature will drop below 32°F (0°C),
check antifreeze to assure proper winter protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance and
do-it-yourself” section.
BATTERY If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “BATTERY” in the “8. Mainte-
nance and do-it-yourself” section.
DRAINING OF COOLANT WATER If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING SYS-
TEM” in the “8. Maintenance and do-it-yourself”
section. TIRE EQUIPMENT SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate your vehicle on snowy or
icy roads, INFINITI recommends the use of MUD
& SNOW or ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire type,
size, speed rating and availability information.
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.
Tire chains may be used. For details, see “TIRE
CHAINS” in the “8. Maintenance and do-it-
yourself” section of this manual.
For all-wheel drive If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.COLD WEATHER DRIVING

CAUTION● Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap while the engine is
still hot. When the radiator cap is removed,
pressurized hot water will spurt out, possi-
bly causing serious injury.
● Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply
the parking brake and move the selector
lever to the P (Park) position (Automatic
transmission models). Move the shift lever
to the N (Neutral) position (Manual trans-
mission models).
Do not stop the engine.
2. Turn off the climate control. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radia-
tor 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.
WARNINGIf steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing or the cooling fan does not run, stop
the engine. WARNINGBe 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 tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.

or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada).IF YOUR VEHICLE OVERHEATS

Rear :
Do not use the tie down hooks
 1
for towing or
vehicle recovery.
CAUTION● Tow chains or cables must be attached only
to the vehicle recovery hooks or main struc-
tural members of the vehicle. Otherwise, the
vehicle body will be damaged.
● Do not use the vehicle tie downs to free a
vehicle stuck in sand, snow, mud, etc.
● Never tow a vehicle using the vehicle tie
downs or recovery hooks. ● Always pull the cable straight out from the
front of the vehicle. Never pull on the vehicle
at an angle.
● Pulling devices should be routed so they do
not touch any part of the suspension, steer-
ing, brake or cooling systems.
● Pulling devices such as ropes or canvas
straps are not recommended for use in ve-
hicle towing or recovery.
Rocking a stuck vehicle If your vehicle is stuck in sand, snow, mud, etc.,
use the following procedure:
1. Turn off the Vehicle Dynamic Control (VDC)
system.
2. Make sure the area in front and behind
the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to
clear an area around the front tires.
4. Slowly rock the vehicle forward and back-
ward.
● Shift back and forth between R (reverse) and
D (drive) (automatic transmission models) or
1st (low) and R (reverse) (manual transmis-
sion models). ● Apply the accelerator as little as possible to
maintain the rocking motion.
● Release the accelerator pedal before shifting
between R and D (automatic transmission
models) or 1st and R (manual transmission
models).
● Do not spin the tires above 35 MPH (55
km/h).
5. If the vehicle cannot be freed after a few
tries, contact a professional towing ser-
vice to remove the vehicle.SCE0891
