Warning
Driving in water can cause loss of vehicle
control or vehicle damage. As water
depths increase, reduce the vehicle speed.

.
than the driver's side front gravel
guard behind the front tire.
Be aware of submerged obstacles.
.
Never open your doors while in water.

Warning
Driving through flowing water can be
dangerous and have an unpredictable
effect on vehicle control. Even shallow
water can wash away the ground from
under your tires. Traction could be lost,
the vehicle could be swept downstream
or the vehicle could roll over. Do not
drive through rushing water.
Caution
Do not drive through standing water if it
is deep enough to cover the gravel
guards. Deep water can damage vehicle
parts.
Before driving in water:
Determine the depth of the water.
.
Enter the water slowly. If the water is
.
deeper than the center of the front hubs,
never exceed 5 km/h (3 mph).
Always drive in the direction of the
.
current.
Avoid oncoming vehicles as they will
.
increase the water depth surrounding
your vehicle.
After exiting the water, repeatedly and
.
gently apply the brakes to dry them off
and restore effectiveness.
After Off-Road Driving
Be sure to switch out of Off-Road Mode or
Terrain Mode on your Driver Mode Control
to return to normal driving.
Remove any brush or debris that has
collected on the underbody or chassis,
or under the hood. Clean the lens of the
underbody camera. These accumulations can
be a fire hazard.
After operation in mud or sand, have the
brake linings cleaned and checked. These
substances can cause glazing and uneven
braking. Check the body structure, driveline,
steering, suspension, wheels, and tires for
damage.
More frequent maintenance service is
required. See the owner's manual.
