(6) While holding the brake pedal down, release and apply the parking brake twice (Step "F").
(7) With the parking brake applied, depress and release the brake pedal twice (Step "G").
(8) Check if the SLIP indicator light comes on (Step "H").
HINT
* If the SLIP indicator light does not come on in step "H", repeat the steps from "A" to "H".
* Turning the ignition switch off ends inspection mode.
(b) Activating inspection mode (Using Techstream)
(1) Ensure that the ignition switch is off and the engine is stopped (Step "A").
(2) Make sure that the shift lever is in the P position (Step "B").
(3) Connect Techstream to the DLC3 (Step "C").
(4) Start the engine (Step "D").
(5) Turn the Techstream main switch on (Step "E").
(6) Select the following menu items: Chassis / ABS/VSC/TRAC / Utility / Inspection Mode (Step "F").
(7) Check that the SLIP indicator light come on (Step "G").
HINT
* If the SLIP indicator light does not come on in step "G", repeat the steps from "A" to "G".
* Turning the ignition switch off ends inspection mode.
10. PRECAUTIONS FOR TOWING FRONT 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.
(c) If a tow truck is not available, in an emergency the vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet(s). This should only be attempted on hard surfaced roads for distances of less than 80 km, and at speeds below 30 km/h (19 mph).
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 front wheels on the ground, the transaxle may be damaged.
(1) Emergency towing procedure
1 Turn the ignition switch ON.
2 Depress the brake pedal and move the shift lever to N.
3 Release the parking brake.
4 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.
* Do not turn off the ignition switch. Turning off the ignition switch may result in engagement of the steering lock, resulting in a hazardous situation or accident.
(d) The towing methods shown below are dangerous and can damage the vehicle, so do not use them.
(1) Do not tow the vehicle facing rearward with the front wheels on the ground.
NOTICE:
* 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 the 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.
11. PRECAUTIONS FOR TOWING ALL WHEEL DRIVE VEHICLES

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 any of the wheels on the ground, the drivetrain may be damaged.
(1) Emergency towing procedure
1 Turn the ignition switch ON.
2 Depress the brake pedal and move the shift lever to N.
3 Release the parking brake.
4 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.
* Do not turn off the ignition switch. Turning off the ignition switch may result in engagement of the steering lock, resulting in a hazardous situation or accident.
(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 two wheels on the ground.
NOTICE:
If the vehicle is towed with only 2 wheels on the ground, the drivetrain may overheat and be damaged, or the wheels may come off the dollies.
(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.
12. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline or gasoline vapors flow into the converter, it may cause overheating and create a fire hazard. To prevent this, observe the following precautions:
(a) Use only unleaded gasoline.
(b) Avoid idling the engine for more than 20 minutes.
(c) Avoid performing unnecessary spark jump tests.
(1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid a prolonged engine compression measurement. Engine compression measurements must be performed as rapidly as possible.
(e) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter.
13. EXPRESSIONS OF IGNITION SWITCH
