WARNING
. The air conditioner cooling function
operates only when the engine is run-
ning.
. Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. On hot, sunny
days, temperatures in a closed vehicle
could quickly become high enough to
cause severe or possibly fatal injuries to
people or animals.
. Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
Start the engine and operate the automatic
climate control system.
NOTE:
.Odors from inside and outside the
vehicle can build up in the air condi-
tioner unit. Odor can enter the passen-
ger compartment through the vents.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into the passenger compartment. This
should help reduce odors inside the
vehicle.
When the “STATUS”button is pushed, the
automatic climate control status screen
will appear. (See “How to use STATUS
button” (P.4-10).)

namic drag..Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following dis-tance behind other vehicles reduces
unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive in providing fuel savings when
driving on flat terrains. 6. Plan for the shortest route.
.Utilize a map or navigation system to
determine the best route to save
time.
7. Avoid idling.
.Shutting off your engine when safe for stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no more than30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal
operating temperature more quickly
while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered
parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, result-
ing in reduced demand on your A/C
system.

recommended ones are used, the VDC
system may not operate properly and
the VDC warning light
may illumi-
nate.
. The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
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 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-7).
BATTERY
If the battery is not fully charged during
extremely 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”
(P.8-15).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-7).

.The T-type spare tire and small size
spare tire are designed for emergency
use. See specific instructions under the
heading “Wheels and tires” (P.8-30).To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
.If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always pre-
sent in the vicinity of the battery. Keep
all sparks and flames away from the
battery.
. Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution which
can cause severe burns. If the fluid
should come into contact with anything,
immediately flush the contacted area
with water.
. Keep the battery out of the reach of
children.
. The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle. .
Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
. Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
. Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away from
it.

speed.
3. If engine overheating is caused by climbing 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
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 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 cool-
ant 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 thecoolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer. When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from an
INFINITI retailer. Local service operators are
familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, INFINITI recommends that
you have a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions.
WARNING
.
Never ride in a vehicle that is being
towed.
. Never get under your vehicle after it has
been lifted by a tow truck.
