Towing of Vehicle
The rear towing eye is located at the
right, below the bumper. The front
towing eye is located on the passenger
side behind a flap in the bumper panel.
Flap removal: Insert finger in recess of
flap and pull flap out.
Flap installation: Engage flap at
bottom and press in top securely.
We recommend that the vehicle be
transported using flat bed equipment.
This method is preferable to other types
of towing.
The vehicle may be towed with all of
the wheels on the ground and the
selector lever in position "N' / neutral
for distances up to 120 km (75 miles)
and at a speed not to exceed 50 km/h
(30 mph).
To positively avoid a possibility of
damage to the transmission, however,
we recommend to disconnect the drive
shaft at the rear axle drive flange on
any towing beyond a short tow to a
nearby garage.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
The use of wheel lift equipment
will damage engine oil pan.
Important!
When transporting vehicle on flat
bed equipment, the front end of
the vehicle must be loaded first.
Additional ramping may be
required for loading to protect
bumper fascia.
Note:
With the engine not running, there is
no power assistance for the braking and
steering systems. In this case, it is
important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the
vehicle.
To signal turns while being towed with
hazard flasher in use, activate
combination switch for left or right
turn signal in usual manner - only the
selected turn signal will operate.
Upon canceling the turn signal, all four
turn signals will operate again.
