wheel torque NISSAN 350Z 2004 Z33 Owners Manual

On slippery surfaces such as wet asphalt roads,
vehicle wheels may spin when the vehicle is
accelerated. This wheel spin reduces accelera-
tion, or causes the vehicle to swerve, thus
decreasing vehicle stability.
When the vehicle drive wheels begin to spin, the
traction control system (TCS) controls the en-
gine torque using an electronic control system,
and it also controls automatic control shifting if
necessary (for automatic transmission models).
This reduces spinning of the drive wheels, and
result in improved vehicle acceleration perfor-
mance. It also improves the vehicle stability by
swerving motion.

When the traction control system is operat-
ing, the slip indicator light in the meter panel
blinks.

If the slip indicator light blinks, the vehicle is
under slippery conditions. Be sure to drive
carefully. See “Slip indicator light” and “Trac-
tion control system (TCS) off indicator light”
in the “2. Instruments and controls” section.

Indicator light
If a malfunction occurs in the traction control
system, the SLIP and
indicator lights
come on in the meter panel.
As long as these indicator lights are on, the
traction control function (except the ABS) is
canceled. The vehicle will behaves like amodel without the traction control system.
WARNING
The traction control system is designed
to prevent the wheels from spinning.
However, it does not prevent vehicle
slipping or spinning due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Be especially careful when driving on
slippery surfaces and always drive
safely.When driving on slippery surfaces or suddenly
avoiding obstacles on roads, the vehicle might
swerve or slip. With the vehicle dynamic control
(VDC) system, sensors detect these movements
and control the braking and engine output to
help improve vehicle stability while driving.

When the vehicle dynamic control system is
operating, the slip indicator light in the meter
panel blinks.

When only the traction control system (TCS)
portion of the vehicle dynamic control system
is operating, the slip indicator light will also
blink.

If the slip indicator light blinks, the vehicle is
under slippery conditions. Be sure to drive
carefully. See “Slip indicator light” and “Ve-
hicle dynamic control (VDC) off indicator
light” in the “2. Instruments and controls”
section.

Installing the spare tireThe spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “8. Main-
tenance and do-it-yourself” section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and tighten the
wheel nuts finger tight. When replacing a
front tire, make sure the hole in the spare tire
wheel is aligned with the pin on the brake
rotor.
3. With the wheel nut wrench, tighten wheelnuts alternately and evenly in the sequence
illustrated (
1
-5) until they are tight.
4. Lower the vehicle slowly until the tire touches
the ground. Then, with the wheel nut wrench,
tighten the wheel nuts securely in the se-
quence as illustrated. Lower the vehicle com-
pletely.
WARNING

Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.

Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.

Retighten the wheel nuts when the
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.Wheel nut tightening torque:
80 ft-lb (108 N⋅m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each lubrication interval.
Adjust tire pressure to the COLD pressure.
COLD pressure:
After vehicle has been parked for three
hours or more or driven less than 1 mile
(1.6 km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to
the driver’s side center pillar.
For models equipped with the low tire
pressure warning system:
After adjusting tire pressure to the COLD tire
pressure, the display of the tire pressure infor-
mation may show higher pressure than the
COLD tire pressure after the vehicle has been
driven more than 1 mile (1.6 km). This is because
the tire pressurizes as the tire temperature rises.
This does not indicate a system malfunction.
Stowing the tire and toolsSecurely store the spare tire and jacking equip-
ment in the vehicle.
