1. Release the parking brake and put the
transmission in neutral.
2. The ignition switch should be in the
“ON” position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.
9-7. Access Key Fob – If
Access Key Fob Does Not Operate ProperlyThe following functions may be inoperable
because of strong radio signals in the
surrounding area or a low battery condi-
tion of the access key fob.
 Locking/unlocking doors including

 Starting engine
In such cases, perform the following
procedure. When t he battery of the
access key fob is discharged, replace it
with a new one. Refer to "Replacing
Battery of Access Key Fob" P376.
CAUTION
 If transmission failure occurs,
transport your vehicle on a flat-
bed truck. Sometime damaged vehicles
cannot be towed because of their
damaged condition. In that case,
use a flat-bed truck for transpor-
tation. The traveling speed must be
limited to less than 20 mph (32
km/h) and the traveling distance
to less than 19 miles (30 km). For
greater speeds and distances,
transport your vehicle on a flat-
bed truck. Use a flat-bed truck if there are
long distance downgrades or
steep slopes. However, do not
apply the brake pedal for a long
time because the engine braking
will not work while towing. Doing
so could overheat the brake. Drive carefully and do not make
an impact on the towing rope by
suddenly starting.
 Use a specific towing rope for
towing. If wire ropes and metal
chains are needed to be used for
towing, wrap the contact portion
of the bumper with cloth to
protect it from damage.

Keep metallic objects, magnetic
sources and signal transmitters
away from the area between the
access key fob and the push-button
