Emergency towingIf 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(s).
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.
For vehicles with an automatic
transmission, only the front tow-
ing eyelet may be used.

352 5-1. Essential information
NOTICE
■To prevent causing serious damage to the transmission when towing
using a wheel-lift type truck (vehic les with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
■ To prevent damage to the vehicle when towing using a wheel-lift type
truck (vehicles with a manual transmission)
●Vehicles without a smart key system: Do not tow the vehicle from the rear
when the engine switch is in the “LOCK” position or the key is removed.
The steering lock mechanism is not strong enough to hold the front wheel\
s
straight.
● Vehicles with a smart key system: Do not tow the vehicle from the rear
when the “ENGINE START STOP” switch is off. The steering lock mecha-
nism is not strong enough to hold the front wheels straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
■ To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■ To prevent causing serious damage to the transmission in emergency
towing (vehicles with an automatic transmission)
Never tow a vehicle from the rear with four wheels on the ground. This may
cause serious damage to the transmission.
