●

Do not use the tire jack for any purpose other than replacing tires or installing and

removing tire chains.

●

Only use the tire jack that comes with this vehicle for replacing a flat tire.

Do not use it on other vehicles, and do not use other tire jacks for replacing tires on

this vehicle.

●

Put the jack properly in its jack point.

●

Do not put any part of your body under the vehicle while it is supported by the jack.

●

Do not start the hybrid system or drive the vehicle while the vehicle is supported by

the jack.

The jack point guides are located under

the rocker panel. They indicate the jack

point positions.

Raise the vehicle until the tire is
slightly raised off the ground.

Remove all the wheel nuts and the

Remove any dirt or foreign matter
from the wheel contact surface.

If foreign matter is on the wheel contact

surface, the wheel nuts may loosen

while the vehicle is in motion, causing

the tire to come off.

Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.

Tighten the wheel nuts until the tapered

portion comes into loose contact with

the disc wheel seat.

WARNING

■

Replacing a flat tire

●

Do not touch the disc wheels or the area around the brakes immediately after the

vehicle has been driven.

After the vehicle has been driven the disc wheels and the area around the brakes will

be extremely hot. Touching these areas with hands, feet or other body parts while

changing a tire, etc. may result in burns.

●

Failure to follow these precautions could cause the wheel nuts to loosen and the tire

to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, leading to

bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts

to loosen and the wheel may fall off, causing a serious accident.

Remove any oil or grease from the wheel bolts or wheel nuts.

• Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5 kgf•m,

76 ft•lbf) as soon as possible after changing wheels.

• When installing a tire, only use wheel nuts that have been specifically designed for

that wheel.

• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes

of the wheel, have the vehicle inspected by any authorized Lexus retailer or Lexus

authorized repairer, or any reliable repairer.

The compact spare tire

●

The compact spare tire is identified by the label “TEMPORARY USE ONLY” on the

tire sidewall.

Use the compact spare tire temporarily, and only in an emergency.

●

Make sure to check the tire inflation pressure of the compact spare tire. (



P. 739)

■

When using the compact spare tire

As the compact spare tire is not equipped with a tire pressure warning valve and trans-

mitter, low inflation pressure of the spare tire will not be indicated by the tire pressure

warning system. Also, if you replace the compact spare tire after the tire pressure warn-

ing light comes on, the light remains on.

■

When the compact spare tire is equipped

The vehicle becomes lower when driving with the compact spare tire compared to when

driving with standard tires.

■

If you have a flat front tire on a road covered with snow or ice

Install the compact spare tire on one of the rear wheels of the vehicle. Perform the follow-

ing steps and fit tire chains to the front tires:

Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.

Connect the jumper cables according to the following procedure:

Connect a positive jumper cable clamp to the exclusive jump starting ter-
minal on your vehicle.
Connect the clamp on the other end of the positive cable to the positive (+)
battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery terminal on the
second vehicle.
Connect the clamp at the other end of the negative cable to a solid, station-
ary, unpainted metallic point away from the exclusive jump starting terminal
and any moving parts, as shown in the illustration.

Start the engine of the second vehicle. Increase the engine speed slightly and
maintain at that level for approximately 5 minutes to recharge the 12-volt bat-
tery of your vehicle.

8-2. Steps to take in an emergency

Close the exclusive jump starting terminal cover, and reinstall the fuse box
cover to its original position.

Once the hybrid system starts, have the vehicle inspected at any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer as soon as
possible.

■

Starting the hybrid system when the 12-volt battery is discharged

The hybrid system cannot be started by push-starting.

■

To prevent 12-volt battery discharge

●

Turn off the headlights and the audio system while the hybrid system is off.

●

Turn off any unnecessary electrical components when the vehicle is running at a low

speed for an extended period, such as in heavy traffic.

■

When the 12-volt battery is removed or discharged

●

The hybrid system may not start. (



P. 608)

●

If the 12-volt battery discharges while the shift position is in P, it may not be possible to

shift the shift position to other positions. In this case, the vehicle cannot be towed with-

out lifting both front wheels because the front wheels will be locked. (



P. 659)

●

When the 12-volt battery is reconnected, start the hybrid system and confirm that the

shift position can be changed to each position using the shift position indicator.

■

Charging the 12-volt battery

The electricity stored in the 12-volt battery will discharge gradually even when the vehicle

is not in use, due to natural discharge and the draining effects of certain electrical appli-

ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the

hybrid system may be unable to start. (The 12-volt battery recharges automatically while

the hybrid system is operating.)

WARNING

■

Avoiding 12-volt battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flammable gas

that may be emitted from the 12-volt battery:

●

Make sure each jumper cable is connected to the correct terminal and that it is not

unintentionally in contact with any other than the intended terminal.

●

Do not allow the other end of the jumper cable connected to the “+” terminal to come

into contact with any other parts or metal surfaces in the area, such as brackets or

unpainted metal.

●

Do not allow the + and - clamps of the jumper cables to come into contact with each

other.

●

Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt

battery.
