Operating tips
•In order to improve the heater operation, clear
the snow and ice from the wiper blade and air
inlet in front of the windscreen.
•After parking in the sun, drive for two or three
minutes with the windows open to vent hot air
from the passenger compartment. Then close
the windows to allow the acceleration of the air
conditioner’s cooling operation.
•Keep the windows closed while the air condi-
tioner is operating.
•The air conditioning system should be operated
for about 10 minutes, at least once a month. This
helps prevent damage to the system due to lack
of lubrication.
•If the coolant temperature warning light comes
on, turn the air conditioner off. For additional
information, see “Engine overheat” in the “6. In
case of emergency” section.
•If the engine coolant reaches an extremely high
temperature, the air conditioning system will au-
tomatically turn off. This may happen for example
if the engine runs at idle speed for a long time on
a hot day.

•In order to improve the heater operation, clear
the snow and ice from the wiper blade and air
inlet in front of the windscreen.
•When the engine coolant temperature and out-
side air temperature are low, the air flow from
the floor outlets may not operate for a maximum
of approximately 150 seconds. However, this is
not a malfunction. After the coolant temperature
has warmed up, the air flow from the floor outlets
will operate normally.
•After parking in the sun, drive for two or three
minutes with the windows open to vent hot air
from the passenger compartment. Then, close
the windows. This will allow the acceleration of
the air conditioner’s cooling operation.
•Keep the windows closed while the air condi-
tioner is operating.
•The air conditioning system should be operated
for approximately 10 minutes at least once a
month. This helps prevent damage to the system
due to lack of lubrication.

NISSAN GREEN PROGRAM
The three-way catalyst is an emission control device
installed in the exhaust system. In the converter,
exhaust gases are burned at high temperatures to
help reduce pollutants.
CAUTION
•The exhaust gas and the exhaust system are
very hot. While the engine is running, keep
people or flammable materials away from the
exhaust pipe.
•Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste pa-
per or rags, as they may burn easily.
•When parking, ensure that people or flam-
mable materials are kept away from the ex-
haust pipe.
TO HELP PREVENT DAMAGE
CAUTION
•Use UNLEADED PETROL ONLY, specifically
the recommended type. For details, see “Ca-
pacities and recommended fuel/lubricants” in
the “9. Technical information” section.
•Do not use leaded petrol. Leaded petrol will
seriously damage three-way catalyst.
Deposits from leaded petrol will seriously re-
duce the three-way catalyst’s ability to help
reduce exhaust pollutants.
•Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems can cause over-rich fuel flow into the
converter, causing it to overheat.
•Avoid driving with an extremely low fuel level.
Running out of fuel could cause the engine to
misfire, damaging the three-way catalyst.
•Do not keep driving if the engine misfires, or
if noticeable loss of performance or other un-
usual operating conditions are detected. Have
the vehicle inspected promptly by a NISSAN
dealer or qualified workshop.
•Do not race the engine while warming it up.
•Do not push or tow your vehicle to start the
engine.The turbocharger system uses engine oil for lubrica-
tion and cooling of its rotating components. The tur-
bocharger turbine turns at extremely high speeds
and it can reach an extremely high temperature. It is
essential to maintain a flow of clean oil through the
turbocharger system. A sudden interruption to the
oil supply may cause a malfunction in the turbo-
charger.
To ensure prolonged life and performance of the
turbocharger, it is essential to comply with the fol-
lowing maintenance procedure:
CAUTION
•Change the engine oil of the turbo-charged
diesel engine as prescribed. See the sepa-
rately provided Warranty Information & Main-
tenance Booklet for additional information.
•Use only the recommended engine oil. See
“Capacities and recommended fuel/
lubricants” in the “9. Technical information”
section.
•If the engine has been operating at high rpm
for an extended period of time, let it idle for a
few minutes prior to shutdown.
•Do not accelerate the engine to high rpm im-
mediately after starting it.

5-4Starting and driving

NOTE
The ESP system cannot be switched off when
the ESP system is operating and the “SLIP” indi-
cator light (
) is blinking.
Push the ESP OFF switch again, or restart the en-
gine, to turn the system ON. See “Electronic Stabil-
ity Programme (ESP) system (where fitted)” earlier
in this section for operational details.
WARNING
•Whatever the conditions, drive with caution.
Accelerate and decelerate with great care. If
accelerating or decelerating too fast, the drive
wheels will lose even more traction.
•Allow more stopping distance in cold weather
driving. Braking should be started sooner than
on dry surfaces.
•Keep at a greater distance from the vehicle in
front of you on slippery roads.
•Wet ice (0°C, 32°F and freezing rain), very cold
snow and ice can be slick and very difficult to
drive on. The vehicle will have a lot less trac-
tion or grip under these conditions. Try to
avoid driving on wet ice until the road is salted
or sanded.
•Watch for slippery spots (black ice). These
may appear on an otherwise clear road in
shaded areas. If a patch of ice is seen ahead,
brake before driving on it. Try not to brake
while actually on the ice and avoid any sud-
den steering manoeuvres.
•Snow can trap dangerous exhaust gas under
your vehicle. Keep snow clear of the exhaust
pipe and from around your vehicle.
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 effi-ciency, the battery should be checked regularly. For
details, see “Battery” in the “8. Maintenance and
do-it-yourself” section.
ENGINE COOLANT
If the vehicle is to be left outside without anti-freeze,
drain the cooling system. Refill before operating the
vehicle. For details, see “Engine cooling system” in
the “8. Maintenance and do-it-yourself” section.
TYRE EQUIPMENT
1) The SUMMER tyres are of a tread design to pro-
vide superior performance on dry surfaces. How-
ever, the performance of these tyres will be sub-
stantially reduced in snowy and icy conditions. If
you operate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD & SNOW
or ALL SEASON tyres on all four wheels. Please
consult a NISSAN dealer or qualified workshop
for tyre type, size, speed rating and availability
information.
2) For additional traction on icy roads, studded
tyres may be used. However, some countries,
provinces and states prohibit their use. Check
applicable laws before installing studded tyres.
CAUTION
Skid and traction capabilities of studded snow
tyres on wet or dry surfaces may be poorer
than that of non-studded snow tyres.
3) Snow chains may be used, if desired. But the
use of snow chains may be prohibited in some
areas. Therefore, check the local laws before
COLD WEATHER DRIVING
Starting and driving5-31

CAUTION
•Three-way catalyst equipped models should
not be started by pushing the vehicle as the
three-way catalyst may be damaged.
•Automatic transmission (AT) models cannot
be started by pushing the vehicle. This may
cause transmission damage.
•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 ve-
hicle.
WARNING
•Never continue driving if the engine of your
vehicle overheats. Doing so could cause a ve-
hicle fire.
•Never open the bonnet if steam is coming
out.
•Never remove the radiator cap (where fitted)
or engine coolant reservoir cap when the en-
gine is hot. If the radiator cap (where fitted) or
engine coolant reservoir cap is removed while
the engine is hot, pressurised hot water will
spurt out and possibly cause burning, scald-
ing or serious injury.
•If steam or coolant is coming out of the en-
gine, stand clear of the vehicle to prevent get-
ting injured.
•The engine cooling fan will start whenever the
coolant temperature exceeds preset degrees.
•Be careful not to allow your hands, hair, jewel-
lery or clothing to come into contact with, or
get caught in, the cooling fan or drive belts.
If the engine of your vehicle is overheating (indi-
cated by the engine coolant temperature warning
light (red)) or if you feel a lack of engine power,
detect an unusual noise, etc., proceed as follows:
1. Move and park the vehicle safely off the road and
away from traffic.
2. Turn on the hazard warning flasher lights.
3. Apply the handbrake.4. Shift the gear lever (M/T models) into the N (Neu-
tral) position [AT models, move the selector lever
to the P (Park) position].
DO NOT STOP THE ENGINE.
5. Open all windows.
6. Switch off the air conditioner system (where fit-
ted).
7. Set the heater or air conditioner temperature
control to maximum “HOT” and fan speed con-
trol to maximum speed.
8. Exit the vehicle.
9. Visually inspect and listen for steam or coolant
escaping from the radiator before opening the
bonnet. Wait until no steam or coolant can be
seen before proceeding.
10. Open the bonnet. For details, see “Bonnet
release” in the “3. Pre-driving checks and
adjustments” section.
11. Visually check if the cooling fan is running.
12. Visually check the radiator and radiator hoses
for leakage.
WARNING
If coolant is leaking, the cooling fan belt is
missing or loose or the cooling fan is not run-
ning, stop the engine.
