CAUTION!
Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, there will be
one in the rear and two mounted on the front of the
vehicle. The rear hook will be located on the driver’s side
of the vehicle.
NOTE:For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.
WARNING!
•Chains are not recommended for freeing a stuck
vehicle. Chains may break, causing serious injury
or death.
•Stand clear of vehicles when pulling with tow
hooks. Tow straps may become disengaged, caus-
ing serious injury.
