GWM Tank 300 Child Seat Guide: ISOFIX Points, Seat Positions and Weight Groups

In the GWM Tank 300, child seats belong in the two outer rear seating positions. The front passenger seat and the rear middle seat are both marked as unsuitable for every weight group. There are four lower fixing points in the gap between the rear backrest and the seat cushion, and three top tether anchor points on the rear of the rear backrest, though some models carry only two. Child seats must meet the ECE R44 specification.

Where a child seat can and cannot go

This is the table that decides everything else.

Attribute Front passenger seat Rear outer seats Rear middle seat
Group 0, up to 10 kg Not suitable Suitable Not suitable
Group 0+, up to 13 kg Not suitable Suitable Not suitable
Group I, 9 to 18 kg Not suitable Suitable Not suitable
Group II, 15 to 25 kg Not suitable Suitable Not suitable
Group III, 22 to 36 kg Not suitable Suitable Not suitable
Measurement (usable positions) Zero Two Zero
ISOFIX fitting available No Yes, both sides No

The front passenger seat is ruled out because it places the child too close to the airbag. In a deployment, that causes severe injury or death.

A rear-facing restraint must never be used on a seat protected by an activated front airbag. That warning appears on the sun visor label for a reason.

Weight groups at a glance

  • Group 0: up to 10 kg, roughly newborn to 9 months
  • Group 0+: up to 13 kg, roughly newborn to 2 years
  • Group I: 9 to 18 kg, roughly 9 months to 4 years
  • Group II: 15 to 25 kg, roughly 4 to 7 years
  • Group III: 22 to 36 kg, roughly 6 to 12 years

Weight decides the group, not age. The age ranges are a guide to typical overlap, not a rule.

Where the anchor points are

Lower fixing points: four of them, in the clearance between the rear seat backrest and the seat cushion. Remove the trim cover over each point before first use.

Top tether points: three on the rear side of the rear backrest. Some models carry only two, at the left and right, so check your own vehicle rather than counting on three. ISOFIX and LATCH seats fit in both lateral rear positions.

One warning is worth repeating in full. These fixing points are designed to withstand only the loads imposed by a correctly fitted child seat. Under no circumstances should they be used for adult seat belts, harnesses, or for attaching any other item or equipment to the vehicle.

That includes cargo nets, dog harnesses and tie-down points for gear. It is a common improvisation and a genuinely dangerous one.

ISOFIX size classes that actually fit

The manual splits ISOFIX seats by size module.

  • Portable bed classes ISO/L1 and ISO/L2 are not suitable
  • Rear-facing classes ISO/R1, ISO/R2 and ISO/R3 suit specific restraint systems on the approved list, not all of them
  • Forward-facing classes ISO/F2, ISO/F2X and ISO/F3 suit general forward-facing ISOFIX restraints in the relevant weight group

So a forward-facing ISOFIX seat is the straightforward fit, while a rear-facing installation depends on that model being on the approved list. Check the seat manufacturer's compatibility list before buying.

Fitting a child seat with the seat belt

  1. Move the front passenger seat as far forward as possible, so it cannot contact the child in the rear.
  2. Adjust the backrest angle of the seat taking the child seat, so the backrest supports it stably.
  3. Adjust or remove the headrest if it can be moved. Otherwise the headrest interferes and the child seat cannot sit flat against the backrest.
  4. Route the shoulder belt along the path marked on the child seat and push the locking tab into the buckle until it clicks.
  5. Press down on the child seat with your body weight while the shoulder belt retracts and tightens. There must be no slack at all.
  6. Shake the child seat gently to confirm it is properly secured.

The same first three steps apply to an ISOFIX or LATCH installation.

The booster seat exception

If you are using a raised seat cushion, do not remove the headrest.

Instead, adjust it so the top of the headrest is flush with, or as close as possible to, the top of the child's head. Do not lower the headrest after fastening the seat.

This is the opposite of the headrest advice for a full child seat, which is exactly why it gets mixed up.

Positioning inside the cabin

Keep the child clear of the pillars and roof rail. Even seated correctly, a head or body leaning against the door pillar or roof rail sits in the path of the curtain airbag, and the deployment force can cause severe injury or death.

Leave space around the child seat. Adjust the seat in front if necessary so nothing crowds the installation.

Secure everything, including the accessories

Do not leave unsecured child seat protection devices loose in the vehicle. Under emergency braking or a severe impact, anything unrestrained becomes a projectile. That applies to seat protectors, spare inserts, cushions and anything else living in the back seat between trips. An airbag fault light also needs inspection, as covered in our warning lights guide.

Child safety locks

For child passengers, the rear seats are the safer position, and the rear doors carry child safety locks.

Insert the mechanical key into the lock hole in the door edge and rotate it to engage, or rotate the other way to release. Once engaged, that door cannot be opened from the inside.

Questions owners actually ask

"Can I fit a child seat in the middle rear seat?" No. The rear middle position is marked as unsuitable for every weight group.

"What if I deactivate the front airbag?" The manual advises against installing a child seat on the front passenger seat regardless, because of proximity to the airbag.

"Do I need to remove the headrest?" For a full child seat, adjust or remove it so the seat sits flat. For a booster cushion, leave it fitted and set it level with the child's head.

"Can I use the ISOFIX points to anchor cargo?" No. They are rated only for a correctly fitted child seat.
