car unsecured.Jacking up the vehicle and re-
moving the tire
WARNING
.Never get under the vehicle while
it is supported only by the jack. If
it is necessary to work under the
vehicle, support it with safety
stands.
. Use the correct jack-up points.
Never use any other part of the
vehicle for jack support.
. Never jack up the vehicle more
than necessary.
. Never use blocks on or under the
jack.
. Do not start or run the engine
while vehicle is on the jack, as it
may cause the vehicle to move.
This is especially true for vehicles with limited slip differentials.
. Do not allow passengers to stay
in the vehicle while it is on the
jack.

until they are tight.
9. Lower the vehicle slowly until the tire touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
illustrated. Lower the vehicle comple-
tely.
WARNING
If the road wheels are hot, allow
them to cool sufficiently before tigh-
tening the wheel nuts. Otherwise, the
wheel nuts cannot be tightened to
specification.
NOTE:.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Inside the vehicleThe maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled mainte-
nance, cleaning the vehicle, etc.
Accelerator pedal:Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Transmission
mechanism: On a fairly
steep hill, check that your vehicle is held
securely with the shift lever in the
position without applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, it is recommended you see

NOTICE
.When the temperature of the
engine coolant and transmission
oil is high or low, the function
cannot be used. The temperature
range in which the R mode start
function can be used:
— Engine coolant: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. If the R mode start function is
used 4 times consecutively, the
function may be disabled and
cannot be turned on to protect
the vehicle system. While the function is disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) When the warning
light turns off, the function can be
used again.
. The performance of start may
vary depending on the amount
of wheel spin ,or increase and
decrease of the engine output in
response to the outside tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. For safety reasons, VDC control
may activate automatically when
driving on a slippery road surface,
such as a wet road, in order to
apply the brakes or limit the
engine output.
. Frequent use of the R mode start
function increases the load on
the powertrain related parts such
as the clutch and transmission
compared to normal driving. In
particular, the clutch will wear out

garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
. Always use tires of the specified
type, size, brand, construction
(bias, bias-belted, radial or run-
flat), and tread pattern on all four
wheels. Failure to do so may
result in a circumference differ-
ence between tires on the front
and rear axles which will cause
excessive tire wear and may da-
mage the transmission, transfer
case and differential gears.
Wheel balanceUnbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance.
Therefore, they should be balanced as
required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the rear wheels on the
vehicle could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information” (Canada) in the Warranty Information
Booklet.

JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.
Make sure the parking brake is
securely applied and the trans-
mission is shifted into the
position.
. Never change tires when the ve-
hicle is on a slope, ice or slippery
areas. This is hazardous.
. Never change tires if oncoming
traffic is close to your vehicle.
Wait for professional road assis-
tance.
Blocking wheelsPlace suitable blocks
at both the front
and back of the wheel diagonally oppo-
site the flat tire to prevent the vehicle
from moving when it is jacked up.
