WARNING
.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. They could
accidentally injure themselves or others
through inadvertent operation of the
vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
. Properly secure all cargo to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.

into the passenger compartment. If you
must drive with the lift gate open, follow
these precautions:
—Open all the windows.
—Set theair recirculation to off
and the fan control to high to
circulate the air.
. If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the lift gate or the body,
follow the manufacturer’s recommenda-
tion to prevent carbon monoxide entry
into the vehicle.

inspected by a qualified mechanic when-
ever:
—The vehicle is raised for service.
—You suspect that exhaust fumes are
entering into the passenger compart-
ment.

PRECAUTIONS WHEN STARTING AND
DRIVING

WARNING
.Do not drive beyond the performance
capability of the tires, even with AWD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result in serious vehicle damage or personal
injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer,
(such as the dynamometers used by
some states for emissions testing), or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.

vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

TOWING RECOMMENDED BY INFINITIGUID-BB74F24E-A3EE-4B73-8BB7-1AE2CF01B7EC
CAUTION
.Never tow automatic transmission mod-
els with the rear wheels on the ground
or four wheels on the ground (forward or
backward), as this may cause serious and expensive damage to the transmis-
sion. If it is necessary to tow the vehicle
with the front wheels raised, always use
towing dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground or
on towing dollies: Push the ignition
switch to the ACC or ON position, and
secure the steering wheel in a straight-
ahead position with a rope or similar
device.

Automatic transmission P (Park) mechan-
ism:On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.

operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull

belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraint/headrest
moves up and down smoothly and that
the locks (if so equipped) hold securely in
all latched positions.
Steering wheel:
Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
