formance, reliab ility and safety of the vehicle and
its many systems.
Improper ma intenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of se rv icing in accordance with
the m aintenance schedule may be a condi tion for
upho ld ing a possib le warranty cla im made w ith in
the warranty period .

fected, creating unnecessary r isks fo r you and
your passengers.
