WARNING
• Do not place objects on the cargo cover
while the vehicle is parked or in motion,
no matter how small. The object on the
cargo cover could cause an injury in an
accident or sudden stop, and/or the
cargo cover can become damaged.
• Do not leave the cargo cover in the ve-
hicle with it disengaged from the holder.
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.

• While pulling up the electronic parkingbrake switch during driving, the parking
brake is applied and a chime sounds. The
electronic parking brake indicator light
(red) in the meter and in the parking brake
switch illuminates. This does not indicate a
malfunction. The electronic parking brake
indicator light (red) in the meter and in the
parking brake switch turns off when the
parking brake is released.
• When pulling the electronic parking brake switch up with the ignition switch in the
OFF or AUTO ACC position, the parking
brake switch indicator light will continue
to illuminate for a short period of time.
WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
• Release the parking brake switch as soonas the engine is delivering enough torque to
the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of automatic
brake hold can be displayed.
To use the automatic brake hold function, the
following conditions need to be met:
• The driver’s seat belt is fastened.
• The electronic parking brake is released.
• The vehicle is not in the P (Park) position.
• The vehicle is not parked on a steep hill.WARNING
• The automatic brake hold function is not
designed to hold the vehicle on a steep
hill or slippery road. Never use the auto-
matic brake hold when the vehicle is
stopped on a steep hill or slippery road.
Failure to do so may cause the vehicle to
move.
• Warnings may appear to request that
the driver retake control by depressing
the brake pedal. •
When the automatic brake hold function
is activated but fails to maintain the ve-
hicle at a standstill, depress the brake
pedal to stop the vehicle. If the vehicle
unexpectedly moves due to outside con-
ditions, the chime may sound and warn-
ings may appear.
• Be sure to deactivate the automatic
brake hold function when using a car
wash or towing your vehicle.
• Make sure to push the park button to
shift to the P (Park) position and apply
the parking brake when parking your ve-
hicle, entering or exiting the vehicle, or
loading luggage. Failure to do so could
cause the vehicle to move or roll away
unexpectedly and result in serious per-
sonal injury or property damage.
WARNING
• If any of the following conditions occur,
the automatic brake hold function may
not function. Have the system checked
promptly. It is recommended that you
visit an INFINITI retailer for this service.
– A warning message appears.
– The indicator light on the automatic
brake hold switch does not illuminate
when the switch is pushed.

are sharply contrasting objects, such
as shadows, snow, water, wheel ruts,
seams, or lines remaining after road
repairs (the Steering Assist could de-
tect these items as lane markers)
– When driving on roads where the
traveling lane merges or separates
• Do not use the Steering Assist under the
following conditions because the system
may not properly detect lane markers.
Doing so could cause a loss of vehicle
control and result in an accident.
– During bad weather (rain, fog, snow,
dust, etc.)
– When rain, snow, sand, etc., is thrown
up by the wheels of other vehicles
– When dirt, oil, ice, snow, water, or an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera –
When the headlights are not bright
due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in brightness
occurs (for example, when the vehicle
enters or exits a tunnel or is under a
bridge)
–
When driving on roads where the trav- eling lane merges or separates or
where there are temporary lane mark-
ers because of road construction
– When there is a lane closure due to
road repairs
– When driving on a bumpy road sur-
face, such as an uneven dirt road
– When driving on sharp curves or
winding roads
– When driving on repeated uphill and
downhill roads
• Do not use the Steering Assist under the
following conditions because the system
will not operate properly:
– When driving with a tire that is not

TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P255/45RF20 size tires. Installation of
the tire chains/cables on P255/45RF20
size tires will cause damage to the vehicle.
If you plan to use tire chains/cables, you
should install P235/55RF19 size tires on
your vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size for
the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions. Use only SAE class “S” chains. Class
“S” chains are used on vehicles with restricted
tire to vehicle clearance. Vehicles that can use
Class “S” chains are designed to meet the
minimum clearances between the tire and the
closest vehicle suspension or body compo-
nent required to accommodate the use of a
winter traction device (tire chains or cables).
The minimum clearances are determined
using the factory equipped tire size. Other
types may damage your vehicle. Use chain
tensioners when recommended by the tire
chain manufacturer to ensure a tight fit. Loose end links of the tire chain must be
secured or removed to prevent the possibility
of whipping action damage to the fenders or
underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 7,500 miles (12,000 km).
For additional information on tire re-
placing procedures, see “Flat tire”
(P. 6-3).
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.

Wheel nut tightening torque:83 ft-lb (113 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times. It is
recommended that wheel nuts be
tightened to specification at each tire
rotation interval.
WARNING
•
After rotating the tires, check and
adjust the tire pressure.
•Do not include the spare tire in the
tire rotation.
•For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire

Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
• Tires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced. •
The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
• Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because some
tire damage may not be obvious.
Replace the tires as necessary to
prevent tire failure and possible
personal injury.
• Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, it is recommended that
you visit an INFINITI retailer for
this service.
