wheel torque NISSAN 350Z 2008 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
engine torque using an electronic control sys-
tem, and it also controls automatic control shift-
ing if necessary (for automatic transmission
models). This reduces spinning of the drive
wheels, and result in improved vehicle accelera-
tion performance. It also improves the vehicle
stability by swerving motion.

When the TCS is operating, the “SLIP” indi-
cator 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 TCS, the “SLIP”
and “TCS OFF” indicator lights come on in
the instrument panel. As long as these indi-
cator lights are illuminated, the traction con-
trol function (except the ABS) is canceled.
The vehicle will behaves like a model without
the TCS.
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 accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the
Vehicle Dynamic Control (VDC) system, sensors
detect these movements and control the braking
and engine output to help improve vehicle sta-
bility.

When the VDC system is operating, the
“SLIP” indicator in the instrument panel
blinks.

If the “SLIP” indicator blinks, the road condi-
tions are slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. See “Slip indicator
light”, and “Vehicle Dynamic Control (VDC)
OFF indicator light” in the “2. Instruments and
controls” section.

Indicator light
If a malfunction occurs in the system, the
“SLIP” and “VDC OFF” indicator lights illumi-
nate in the instrument panel. As long as these
indicators are illuminated, the VDC system
function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) system to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel, which
distributes the driving power to the other driving
wheel. If the vehicle is operated with the VDC

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.
Stowing the damaged tire and toolsSecurely store the spare tire and jacking equip-
ment in the vehicle.
WARNING

Always make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an
