2011 INFINITI G-COUPE cooling

WARNING
●The air conditioner cooling function oper-
ates only when the engine is running.
● 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 in-
juries 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.
When the “STATUS” button is pushed, the
automatic climate control status screen will
appear. (See “HOW TO USE STATUS BUTTON”
earlier in this section.) You can individually set the driver and front
passenger side temperature using each tem-
perature control button.

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.
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
5-56Starting and driving

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.
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 leak-
ing 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 reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
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). When towing your vehicle, all State (Provincial
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 appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental dam-
age to your vehicle, INFINITI recommends that
you have a service operator tow your vehicle. It
is advisable to have the service operator care-
fully read the following precautions.WARNING
●
Never ride in a vehicle that is being towed.
● Never get under your vehicle after it has been
lifted by a tow truck.
CAUTION
● When towing, make sure that the transmis-
sion, axles, steering system and powertrain
are in working condition. If any unit is dam-
aged, dollies must be used.
● Always attach safety chains before towing.
TOWING YOUR VEHICLE
In case of emergency6-11

●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.
