All.
When you are driving though water do not
exceed 4 mph (7 km/h).
WATER WADING WARNING:
Do not attempt to
cross a deep, fast flowing body of water.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
As the water depth increases, you must
reduce your vehicle speed to avoid
potential vehicle damage. •
Always determine the depth before
attempting a water crossing. Never
drive through water that is higher than
the bottom of the wheel hubs.
• Slowly proceed and avoid splashing
water any more than is necessary. •
Be aware that obstacles and debris
may be beneath the water ’s surface.
• Keep the doors fully closed during the
water crossing.
• After driving through water and as soon
as it is safe to do so check the brakes,
horn, lights, and steering wheel to
confirm those systems are functioning
properly.
Note: Engine damage can occur if water
enters the air filter.
