(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
After starting the engine, fully depress the foot
brake pedal and push the shift lever button
before shifting the shift lever to the R (Reverse) ,
N (Neutral) , D (Drive) or Manual shift mode
position. Be sure the vehicle is fully stopped
before attempting to shift the shift lever.
This automatic transmission model is de-
signed so that the foot brake pedal must
be depressed before shifting from P (Park)
to any drive position while the ignition
switch position is ON.
The shift lever cannot be moved out of the
P (Park) position and into any of the other
gear positions if the ignition switch is
pushed to the LOCK, OFF or ACC position. 1. Keep the foot brake pedal depressed and
push the shift lever button to shift into a
driving gear.
2. Release the parking brake and foot brake, then gradually start the vehicle in motion.
WARNING
.Do not depress the accelerator
pedal while shifting from P (Park)
or N (Neutral) to R (Reverse) D
(Drive) , or manual shift mode. Al-
ways depress the brake pedal until
shifting is completed. Failure to do
so could cause you to lose control
and have an accident.
. Cold engine idle speed is high, so
use caution when shifting into a
forward or reverse gear before the
engine has warmed up.
. Never shift to P (Park) or R (Re-
verse) while vehicle is moving for-
ward. Never shift to P (Park) or D
(Drive) while vehicle is moving rear-
ward. Failure to do so could cause
you to lose control and have an
accident.

SynchroRev Match mode (S-MODE) op-
eration:
The SynchroRev Match mode (S-MODE) auto-
matically adjusts the engine speed by controlling
the engine throttle. The accelerator pedal does
not have to be depressed.
The system detects the clutch pedal and shift
lever operations, and then calculates the target
engine speed using the shifting gear position
and the vehicle speed information.
The system provides accurate engine speed
control that helps achieve quick gear shifting
and reduces shift shock on clutch engagement.
. When downshifting:
The engine speed is automatically increased
to the target engine speed before the clutch
is engaged.
. When upshifting:
The engine speed is automatically kept after

5-32Starting and driving
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 328F(08C) ,
check antifreeze to assure proper winter protec-
tion. For additional information, see “Engine
cooling system” (P.8-8).
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 efficiency, the battery should
be checked regularly. For additional information,
see “Battery” (P.8-15) .
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 system”
(P.8-8) .
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, NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four wheels.
Consult a NISSAN dealer 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” (P.8-36) of this manual.
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
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
.Wet ice (328F, 0 8C 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 down-
shifting 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 pave-
ment.
. Allow greater following distances
on slippery roads.
COLD WEATHER DRIVING

6-14In case of emergency
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. .
Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles or
industrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery when jump starting.
. Do not attempt to jump start a
frozen battery. It could explode
and cause serious injury.
. Your vehicle has an automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other
objects away from it.

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.
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.
