2WD MODELS
NBGI0008S0402
INFINITI recommends that vehicle be towed with the driving (rear)
wheels off the ground as illustrated.
CAUTION:
I
When towing manual or automatic transmission models
with the front wheels on the ground: Turn the ignition key
to the OFF position and secure the steering wheel in a
straightahead position with a rope or similar device. Never
place the ignition key in the LOCK position. This will result
in damage to the steering lock mechanism.
I
When towing manual transmission models with the rear
wheels on the ground or four wheels on the ground (if you
do not use towing dollies): Always release the parking
brake and move the transmission shift lever to the N (neu-
tral) position.
Observe the following restricted towing speeds and distances.
Manual transmission models:
I
Speed: Below 95 km/h (60 MPH)
I
Distance: Less than 800 km (500 miles)
If the speed or distance must necessarily be greater, remove the
propeller shaft beforehand to prevent damage to the transmission.

VEHICLE RECOVERY
NBGI0008S0401
I
Use the towing hook only, not other parts of the vehicle.
Otherwise, the vehicle body will be damaged.
I
Use the towing hook only to free a vehicle stuck in sand, snow,
mud, etc. Never tow the vehicle for a long distance using only
the towing hook.
I
The towing hook is under tremendous force when used to free
a stuck vehicle. Always pull the cable straight out from the front
or rear of the vehicle. Never pull on the hook at a sideways
angle.
I
Stand clear of a stuck vehicle.
