. 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
present 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 con-
tacted 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.

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 (and) to bring their batteries into close
proximity to each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the shift lever to the P (Park) position. Switch off all
unnecessary electrical systems (light,
heater, air conditioner, etc.).
3. Remove vent caps on the battery (if so equipped). Cover the battery with a
firmly wrung out moist cloth
to reduce
explosion hazard.
4. Connect jumper cables in the sequence as illustrated (
???).
For models with a steering wheel lock
mechanism: If the battery is discon-
nected or discharged, the steering wheel
will lock and cannot be turned. Supply
power using jumper cables before push-
ing the ignition switch and disengaging
the steering lock.

CAUTION
.Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (as illustrated) − not to the
battery.
. Make sure the jumper cables do not
touch moving parts in the engine
compartment and that 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 vehicle
at about 2,000 rpm, and start
the engine 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, push the
ignition switch to the OFF position and
wait 10 seconds before trying again.
7. After starting your engine, carefully disconnect the negative cable and then
the positive cable (

pushing.
CAUTION
.
Automatic transmission models can-
not be push-started or tow-started.
Attempting to do so may cause
transmission damage.
. Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause the
vehicle to collide with the tow vehi-
cle.

6-12In case of emergency
CAUTION
.Do not continue to drive if your
vehicle overheats. 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, possibly
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
shift lever to the P (Park) position.
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
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 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 tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.
