(a) HINTS ON OPERATIONS

1	Attire	Always wear a clean uniform. A hat and safety shoes must be worn.
2	Vehicle protection	Prepare a grille cover, fender cover, seat cover and floor mat before starting work.
3	Safety procedures	When working with 2 or more persons, be sure to check the safety of one another. When working with the engine running, make sure to provide ventilation for exhaust fumes in the workshop. If working on high temperature, high pressure, rotating, moving or vibrating parts, wear appropriate safety equipment and take extra care not to injure yourself or others. When jacking up the vehicle, be sure to support the vehicle at the specified locations with safety stands. When lifting up the vehicle, use appropriate safety equipment.
4	Preparation of tools and measuring equipment	Before starting work, prepare a tool stand, SST, measuring equipment, oil, and any replacement parts required.
5	Removal and installation, disassembly and assembly operations	Diagnose with a thorough understanding of proper procedures and of the reported problem. Before removing any parts, check the general condition of the assembly and for deformation and damage. If the procedure is complicated, take notes. For example, note the total number of electrical connections, bolts or hoses removed. Add matchmarks to ensure reassembly of components in the original positions. Temporarily mark hoses and their fittings if needed. Clean and wash the removed parts if necessary and assemble them after a thorough check.
6	Removed parts	Place the removed parts in a separate box to avoid mixing them up with new parts or contaminating the new parts. For non-reusable parts such as gaskets, O-rings and self-locking nuts, replace them with new ones as instructed in this manual. Retain the removed parts for customer inspection, if requested.
7*	Checks to perform after work is finished	Make sure that removed and installed parts (oil filler cap, level dipstick, floor mat, etc.) are properly installed/tightened. Make sure that none of the cloths or tools that were used have been left in the engine compartment or within the vehicle. Check that there are no oil leaks.

CAUTION:

*: Be sure to perform these checks properly, not performing these checks properly after finishing work can lead to a serious accident or injury.

(b) JACKING UP AND SUPPORTING THE VEHICLE

(1) Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations.

*a	Seal Lock Adhesive

(1) Precoated parts are bolts and nuts that are coated with seal lock adhesive at the factory.

(2) If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive.

(3) When reusing a precoated part, clean off the old adhesive and dry the part with compressed air. Then apply new seal lock adhesive appropriately to that part.

(4) Some seal lock agents harden slowly. You may have to wait for the seal lock adhesive to harden.

(d) SMALL-HEAD BOLTS

(1) Small-head bolts are bolts with a smaller bolt head than standard bolts with the same thread diameter and flange diameter.

*A	Example: M6 Bolt
*a	Ring Mark
*b	Black

(2) Although the size of the bolt head is smaller than a standard bolt, the tightening torque remains unchanged as the thread diameter and flange diameter are not different. Make sure to tighten all small-head bolts to the correct torque indicated in the repair manual.

(3) As the force applied to the sides of the head of a small-head bolt is higher than that of a standard bolt when the same tightening torque is used, the height of the bolt head has been increased to ensure its strength.

(4) For identification purposes, small-head bolts are black and the bolt head is marked with a ring.

(e) GASKETS

(1) When necessary, use a sealant on gaskets to prevent leaks.

(f) BOLTS, NUTS AND SCREWS

If the vehicle is towed facing rearward with the front wheels on the ground, the drivetrain may overheat and be damaged.
In addition, if the vehicle is equipped with a VSC system, the system may apply the brakes to the rotating wheels.

(2) Do not use a sling-type towing method either from the front or rear.

NOTICE:

If a sling-type tow truck is used, damage may occur to the vehicle body.

PRECAUTIONS FOR TOWING REAR WHEEL DRIVE VEHICLES

(a) Use one of the following methods to tow the vehicle.

(b) If the vehicle has trouble with the chassis or drivetrain, use method 1 (flatbed truck).

NOTICE:

Do not use any towing method other than those shown above.
*1: If the vehicle is tilted after parking on a level surface, the braking force may be insufficient as the electric parking brake determines how much braking force to apply by automatically detecting the slope of the road. (w/ Electric Parking Brake System)

HINT:

*2: For the procedure to apply the maximum amount of braking force, refer to Precaution of Electric Parking Brake System.

A driver must be in the vehicle to steer and operate the brakes. The vehicle's wheels, drivetrain, axles, steering and brakes must be in good condition.

NOTICE:

If the towing speed or distance exceeds the above limits, or the vehicle is towed in a backward direction with the wheels on the ground, the drivetrain or vehicle may be damaged.

(1) Emergency towing procedure

w/o Electronic Shift Lever System:

Turn the ignition switch to ON (IG).
Depress the brake pedal and move the shift lever to N.
Release the parking brake.
Release the brake pedal slowly.

w/ Electronic Shift Lever System:

Turn the ignition switch to ON (IG).
Depress the brake pedal, move the shift lever to N and confirm that neutral (N) has been selected.
Release the parking brake.
Release the brake pedal slowly.

NOTICE:

Use extreme caution when towing the vehicle. Avoid sudden starts or erratic driving maneuvers which place excessive stress on the emergency towing eyelet and the cables or chains.
If the hybrid system is off, the power assist for the brakes and steering will not function, making steering and braking more difficult. (for HV Model)
Do not turn off the ignition switch. Turning off the ignition switch may result in engagement of the steering lock or the parking lock, resulting in a hazardous situation or accident.

HINT:

w/ Electronic Shift Lever System:

Neutral (N) cannot be selected if the auxiliary battery is discharged or if it has been disconnected.
There is a possibility that neutral (N) cannot be selected when parts related to the electronic shift lever system are malfunctioning.

(d) The towing methods shown below are dangerous and can damage the vehicle, so do not use them.

(1) Do not tow the vehicle with only 2 wheels on the ground.

CAUTION:

If the vehicle is towed with only the front wheels on the ground, the steering may move, causing the vehicle to become unstable.

NOTICE:

If the vehicle is towed with only the rear wheels on the ground, the drivetrain may overheat and be damaged.

(2) Do not use a sling-type towing method either from the front or rear.

NOTICE:

If a sling-type tow truck is used, damage may occur to the vehicle body.

PRECAUTIONS FOR TOWING ALL WHEEL DRIVE VEHICLES
