boat launching or retrieval,
• Do not allow the static water
level to rise above the bottom
edge of the rear bumper and
• Do not allow waves to break
higher than 15 cm (six inches)
above the bottom edge of the
rear bumper.
Exceeding these limits may allow
water to enter critical vehicle
components, adversely affecting
driveability, emissions and
reliability.
If the rear axle is submerged in
water, the rear axle lubricant
should be checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
