the Park button. This may damage the
shift control system.
Use this position when the vehicle is parked
or starting the engine. Always make sure that
the vehicle is completely stopped before
pressing the Park button
O1to engage the P
(Park) position. For maximum safety, the
brake pedal must be depressed before en-
gaging the P (Park) position. Use this position
together with the parking brake. When park-
ing on a hill, first depress the brake pedal,
apply the parking brake and then engage the
P (Park) position. The parking lock should not
be used as a brake when parking. In order to secure the vehicle, always apply the elec-
tronic parking brake in addition to the parking
lock.
In the event of a malfunction of the vehicle’s
electronics, the transmission may lock in the
P (Park) position. Have the vehicle’s electron-
ics checked immediately. It is recommended
that you visit an INFINITI retailer for this
service.
The P (Park) position is automatically en-
gaged if:
• You switch off the ignition switch.
• You unfasten the driver’s seat belt and
open the driver’s door when the vehicle is
stationary or driving at a very low speed
and the transmission is in the D (Drive) po-
sition or R (Reverse) position.
R (Reverse)
CAUTION
To prevent transmission damage, use the R
(Reverse) position only when the vehicle is
completely stopped. Use the R (Reverse) position to back up. Make
sure the vehicle is completely stopped before
selecting the R (Reverse) position.
The brake
pedal must be depressed and the shift lever
button pressed to move the shift lever from
the home position to R (Reverse).
If the vehicle is placed in the R (Reverse)
position while forwarding, the chime will
sound and the vehicle will switch into the N
(Neutral) position.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
“Engine cooling system” (P. 8-4).
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” (P. 8-12).
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 additional information, see
“Changing engine coolant” (P. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. 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. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud- ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial 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.
3. Tire chains may be used. For additional information, see “Tire chains”(P. 8-37).
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-move 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 washer fluid to refill the windshield- washer fluid reservoir.
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 accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
• Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
• Allow greater following distances on
slippery roads.
COLD WEATHER DRIVING
Starting and driving5-153

Doors and engine hood:Check that the doors
and engine hood operate properly. Also en-
sure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication
frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays or
struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are miss-
ing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance schedule.
Tires*: Check the pressure with a gauge of-
ten and always prior to long distance trips. If necessary, adjust the pressure in all tires, in-
cluding the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor:
It is recommended that
you replace the TPMS tire pressure sensor
assembly when the tires are replaced due to
wear or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility. It is recommended that you have
a damaged windshield repaired by an INFINITI
retailer, or an INFINITI Certified Collision Cen- ter. To locate a collision center in your area,
refer to http://collision.infinitiusa.com.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:
Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Brake pedal: Check the pedal for smooth op-
eration. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately.
It is recommended that you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Continuously Variable Transmission (CVT) P
(Park) position mechanism: On a fairly steep
hill check that the vehicle is held securely with
the shift position in the P (Park) position
without applying any brakes.
