TACHOMETER
The tachometer indicates engine speed in revo-
lutions per minute (RPM).Do not rev the engine
into the red zone
1.
CAUTION
When engine speed approaches the red zone,
shift to a higher gear or reduce engine speed.
Operating the engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant tem-
perature.
The engine coolant temperature is within the
normal range when the gauge needle points
within the zone
1shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates engine coolant tempera-
ture near the hot (H) end of the normal range,
reduce vehicle speed to decrease temperature.
If gauge is over the normal range, stop the
vehicle as soon as safely possible. If the engine
is overheated, continued operation of the ve-
hicle may seriously damage the engine. See “IF
YOUR VEHICLE OVERHEATS” in the “6. In case of
emergency” section for immediate action
required.

OPERATING TIPS
When the engine coolant temperature and out-
side air temperature are low, the air flow from
the foot outlets may not operate. However, this
is not a malfunction. After the coolant tempera-
ture warms up, the air flow from the foot outlets
will operate normally.
The sensors
AandBlocated on the instru-
ment panel help maintain a constant tempera-
ture. Do not put anything on or around the
sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control Sys-
tem:
The climate control system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner
heats, defogs, and ventilates efficiently, replace
the filter in accordance with the maintenance
schedule in the INFINITI Service and Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer.
The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system. Models with Advanced Climate Control System:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects and neutralizes dirt, pollen, dust, etc. To
make sure that the air conditioner heats, defogs
and ventilates efficiently, replace the filter in
accordance with the maintenance schedule in
the INFINITI Service and Maintenance Guide. To
replace the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.SAA3088

5. To stop the engine, shift the selector leverto the P (Park) position and push the
ignition switch to the OFF position.ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tempera-
ture with heavy loads, such as when towing a
trailer).
When the engine temperature reaches a certain
level:
● The engine coolant temperature gauge will
move toward the H position.
● Engine power may be reduced.
● The air conditioning cooling function may be
automatically turned OFF for a short time
(the blower will continue to operate).
Engine power and, under some conditions, ve-
hicle speed will decrease. Vehicle speed can be
controlled with the accelerator pedal, but the
vehicle may not accelerate at the desired
speed. The transmission will downshift or up-
shift as it reaches prescribed shift points. You
can also shift manually.
As driving conditions change and engine cool-
ant temperature is reduced, vehicle speed can
be increased using the accelerator pedal, and
air conditioning cooling function will automati-
cally be turned back ON. If:1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tem-
perature gauge does not return to the
normal range from the H position, this
may indicate a malfunction. Move the
vehicle off the road to a safe area and
allow the engine to cool. If after checking
the oil and coolant, the
remains on
or engine coolant temperature does not
return to the normal range, do not con-
tinue to drive and contact an INFINITI
retailer.
The Malfunction Indicator Light (MIL)may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon by an INFINITI retailer.
See “WARNING/INDICATOR LIGHTS AND AU-
DIBLE REMINDERS” in the “2. Instruments and
controls” section.

tor light on the meter panel will then blink to
warn the driver.
● If the engine coolant temperature becomes
excessively high, the cruise control system
will be canceled automatically.
● If the CRUISE indicator light blinks, turn the
cruise control main switch off and have the
system checked by your INFINITI retailer.
● The CRUISE indicator light may sometimes
blink when the cruise control main switch is
turned ON while pushing the RESUME/
ACCELERATE, SET/COAST or CANCEL switch.
To properly set the cruise control system,
perform the steps below in the order indi-
cated.

CRUISE CONTROL
Starting and driving5-37

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 four-wheel drive
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.
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 window washer fluid to refill the reser-
voir tank.
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.
● Whatever the condition, drive with caution.
Accelerate and slow down with care. If accel-
erating or downshifting too fast, the drive
wheels will lose even more traction.
COLD WEATHER DRIVING
Starting and driving5-101

●Allow more stopping distance under these
conditions. Braking should be started
sooner than on dry pavement.
● Allow greater following distances on slip-
pery 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 steer-
ing maneuvers.
● Do not use the cruise control on slippery
roads.
● Snow can trap dangerous exhaust gases un-
der your vehicle. Keep snow clear of the ex-
haust pipe and from around your vehicle.ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in 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 engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
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 least2-4hours, 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 electrical system or a
2-pronged adapter. You can be seriously in-
jured by an electrical shock if you use an
ungrounded connection.
● Disconnect and properly store the engine
block heater cord before starting the engine.
Damage to the cord could result in an electri-
cal shock and can cause serious injury.
● Use a heavy-duty 3-wire, 3-pronged exten-
sion cord rated for at least 10A. Plug the
extension 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 electri-
cal shock and cause serious personal injury.
5-102Starting and driving

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.
8. After starting your engine, carefully dis-connect the negative cable and then the
positive cable (
4→3→2→1).
9. 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.
10. Put the battery cover on.
Do not attempt to start the engine by pushing.
CAUTION
● Automatic transmission models cannot 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 vehicle.
If needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada).
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 or coolant reservoir
cap while the engine is still hot. When the
radiator cap or coolant reservoir cap is re-
moved, 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 selector
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.
