how do I know when it's in 4WD & can I use low range?

We have a 2011 Grand Cherokee.
When we bought it the salesman said it would always know when to engage the 4WD.
I suppose that's true. Last winter I crashed through a snowbanking, up (hill on) the lawn at the local high school and through the snowbanking on the top. Never missed a beat.
So I know it works fine, but there's no idicator that it's in 4WD.
No little green light or a yellow 4X4 or anything.

Also, does this mean I have no low range?

Please advise.

Thanks.

Your Jeep is all wheel drive, and under normal driving conditions sends torque 48% to the front and 52% to the rear wheels. It will automatically send more torque to an individual wheel if wheel spin/slip is detected. Which model/engine Grand Cherokee is it? There is never a two wheel drive mode, it's always in 4wd. Read your owner's manual to learn how to engage 4-lo, which you will probably never need.

Can't wait for snow in Virginia to go out and play. If you have plenty of snow you can cut the wheels slightly right and goose it to see snow fly off the left front wheel. It's fun too. You bought a great Jeep, enjoy.

You have a WK2 - you'll probably get better feedback in the WK2 sub-forums. This is the WK side ('05-'10).

Attached is a picture of the Transfer Case Switch.

From the 2011 WK Owner Manual:
FOUR-WHEEL DRIVE OPERATION

Quadra-Trac I_ Operating Instructions/
Precautions – If Equipped

The Quadra-Trac I_ is a single-speed (HI range only)
transfer case, which provides convenient full-time fourwheel
drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE: The Quadra-Trac I_ system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Operating”
for further information.

Quadra-Trac II_ Operating Instructions/
Precautions – If Equipped

The Quadra-Trac II_ transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II_
transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
