Emergency towing
If a tow truck is not available, in an emergency your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet. This should only be attempted on hard surfaced roads
for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.

Towing with a sling-type truck
Do not tow with a sling-type truck
to prevent body damage.
Towing with a wheel-lift type truck
From the front (2WD models)
Release the parking brake.
From the front (AWD models)
Use a towing dolly under the rear
wheels.

394 5-1. Essential information
From the rear
Automatic transmission: Use a
towing dolly under the front
wheels.
Manual transmission: We recom-
mend to use a towing dolly under
the front wheels.
When not using a towing dolly,
turn the engine switch to the
“ACC” position and shift the shift
lever to N.
Using a flat bed truck
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45.
Do not overly tighten the tie
downs or the vehicle may be
damaged.
■Emergency towing procedure
Release the parking brake.
Shift the shift lever to N.
Turn the engine switch to the “ACC” (engine off) or “ON” (engine
running) position.

CAUTION
■Caution while towing
●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. Always
be cautious of the surroundings and other vehicles while towing.
●If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.

Event data recorder
In a crash or a near car crash event
The SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
●Engine speed
●Whether the brake pedal was applied or not
●Vehicle speed
●To what extent the accelerator pedal was depressed
●Position of the transmission shift lever
●Whether the driver and front passenger wore seat belts or not
●Driver's seat position
●SRS airbag deployment data
●SRS airbag system diagnostic data
●Front passenger's occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assist in driving and maintaining
optimal vehicle performance.
Besides storing data useful for troubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.
